Le poulet de chair a connu une amélioration spectaculaire de sa productivité, grâce aux progrès concomitants des méthodes d’élevage, de la nutrition, de la génétique et de la médecine vétérinaire. Notre travail porte sur l’évaluation des performances technico- économiques des élevages de poulet chair dans la région de Msila. Pour cela, des enquêtes sur terrain ont concernés 33 producteurs avec 80 bâtiments d’élevage. L’étude technique consiste à déterminer les conditions d’élevage (le bâtiment, la construction, la superficie...), l’aspect économique porte sur l’estimation des charges directes et indirectes et les bénéfices réalisés. Les résultats de notre enquête montrent que la densité moyenne au niveau des bâtiments est de 9,73±1,55 sujets/m², le GMQ est de 63,56±4,27 g/sujet/J, le taux de mortalité est de 2,69±1,76 %, l’âge et le poids à l’abattage sont de 46,99±1,97 jours et 3,01±0,25 g. L’indice de consommation moyen est de 1,97±0,04 et l’index de production est estimé à 315,6±22,18. L’observation des résultats du coût de production et du prix de revient chez 4 éleveurs de la région montre que le budget de l’alimentation et celui de l’achat des poussins occupent une part très importante dans les frais d’investissement.

Abstract: The preservation of the Algerian Phoenician heritage and the use of dry dates Hchef variety (Phoenix dactyliferaL.) for ruminant feeding will have a positive impact on the national economy. This co-product of poor quality and low market value has been shown to be rich in various secondary metabolites endowed with anti-oxidant and anti-radical properties. In order to make the most of our Algerian oasian flora, a potential source of bioactive natural molecules, a chemical and biological study of three parts of the fruit (‘N’ stone, ‘P’ pulp and ‘N+P’ date waste) was carried out. After the fruit harvest, a representative sample of date waste (5kg) is recovered from palm groves in the Biskra region (Algeria), for the purpose of conducting phytochemical analyses to assess the secondary metabolites responsible for biological activity. These tests were carried out at the Constantine CRBT biotechnology research centre and at LURPHATOX. Based on Topçu et al. (2007) and Müller et al. (2010), total polyphenol content (TPC) and total flavonoic content (TFC) were determined. The antioxidant activity of extracts (crude and fractions) of declassified dates was evaluated and compared using spectrophotometric methods: DPPH (Blois 1958), ABTS (Re et al., 1999), CUPRAC (Apak et al., 2004) and the 50% inhibitory concentration (IC50). The phytochemical assay revealed a high content of polyphenols for the P+N part of the methyl ethyl ketone (Mec) phase as well as flavonoids for the N part of the Mec fraction. In addition, the Mec phase of date waste showed a better anti-free radical activity with the DPPH test. The bioactive substances isolated in the stone fractions showed excellent antioxidant activity with the ABTS test. Moreover, the raw extract of N showed an excellent anti-oxidant activity superior to that of the standard BHT (Butyl hydroxy toluene) with the CUPRAC test.

Abstract: The present work aims to evaluate the anti-dermatophyte activity and to investigate the chemical composition of Pistacialentiscus leaves (PLE), Lawsoniainermis (LIN) and bark of Juglansregia (JRE). A bioguided phytochemical screening revealed the presence of four major chemical groups (tannins, flavonoids, sterols and terpenoids and saponins) for our three selected plant extracts. These chemical groups are known for their activities could be responsible for antifungal activities observed. CMTC on silica and polyamide gel and HPLC confirmed the results of the reaction characterization. The resulting chromatograms revealed under UV light before and after detection Neu reagent gave an idea about the nature of phenolic compounds, mainly flavonoids. Revelation for Liebermann-Burchard FeCl3 reagent and showed the presence of sterols, terpenes and tannins. Flavonoids extracted from phases of ethyl acetate, DE, water and 1B identified by UV-Visible Atomic to confirm the presence of flavonol, flavone, chalcone, Aurone molecules, present in isoflavonethree plants. The activity of the extract obtained in successive phases of the confrontation was remarkable for the Candida albicans,single strain inhibited by most different fractions (ED, AC, 1B) of three plants. This partition allowed us to cope with the possible consequences of loss and phytochemical fractionation induced activity. Keywords:Juglansregia, Lawsoniainermis, Pistacialentiscus, fractions, antifungalactivity.

Abstract The date palm (Phoenix dactylifera L.) which is the pivot of oasian agriculture, offers a range of agricultural by-products, which remains very poorly exploited and still in a traditional way in the ration of small ruminants. Date waste is the result of sorting after harvest, accounting for 25% of annual date production. This co-product of poor quality and low market value has been shown to be rich in various secondary metabolites endowed with anti-oxidant and anti-radical properties. In order to make the most of our Algerian oasian flora, a potential source of bioactive natural molecules, a chemical and biological study of three parts of the fruit of the Phoenix dactylifera plant (‘N’ stone, ‘P’ pulp and ‘N+P’ date waste) was carried out. After the date harvest (November 2021), a representative sample of date waste (5kg) is recovered from palm groves in the Biskra region (Algeria), for the purpose of conducting forage and phytochemical analyses to assess the nutritional value and secondary metabolites responsible for biological activity. These tests are carried out at the Constantine CRBT biotechnology research centre and at LURPHATOX. Based on Topçu et al. (2007) and Müller et al. (2010), total polyphenol content (TPC) and total flavonoic content (TFC) were determined. According to AOAC (1999), forage analyses were conducted on the determination of dry matter (DM), organic matter (OM), raw ash (CT), Crude protein (MAT) by the Kjeldahl method, parietal carbohydrates (NDF, ADF and ADL) by the Van Soest method, raw cellulose (CT) by the Weende and method and total fat (GM) by the continuous Soxhlet extraction method. The antioxidant activity of extracts (crude and fractions) of declassified dates was evaluated and compared using spectrophotometric methods: the method for determining the oxidation of radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) (Blois 1958), the trapping activity of the radical cation ABTS (2,20-azinobis[3-ethylbenzothiazoline-6-sulfonate]) (Re et al., 1999) and the reduction of the copper-neocuproen complex (CUPRAC) (Apak et al., 2004) and the 50% inhibitory concentration (IC50) is determined.

AbstractAbstract Intra-mammary infections remain a severe issue by which a healthy udder produces hygienic milk. However, in the case of the gland infection or one of itsquarters, the milk is secreted with germs as a result of poor environmental and milking hygiene. In thiscontext, the aim of the followingwork was to evaluate the health management of dairy cattle farms in the M'sila region through the evaluation of the prevalence of mastitis precisely subclinical mastitis,which constitutes a major obstacle to the development of the milk industry in our country. A survey has been conducted through distributing a questionnaire to 22 farms that belong to 5 communes of the Wilaya of M'sila. The survey focused on the hygiene conditions of the building and the milking.The screening of subclinical mastitis was carried out on a population made of 167 cows of different breeds (Holstein, Montbéliarde, Normandes, Red Pie) in lactating, at 07 cattle farms using two tests, which are black plate, and California Mastitis Test CMT. The CMT detection test showed positive results in 20 cows among the 167 cows tested with a frequency of 12%. The infectedcows have a mammary infection, in one or more quarters. In accordance with, from the 668 teatstested, there were 628 teats found to have a score of 0 (negative), that is, a frequency of 94%. 40 teats tested positive for CMT with a frequency of 6%, where 14 teats tested positive for Grade ≥ 2 at CMT and 26 teats tested positive for Grade between 1 and 2. All samples for mastitis screening by the black plate test were negative. The CMT is an interesting test and its results are reliable for the diagnosis of subclinical mastitis in dairy cattle. Keywords: Dairy’s conditions, screening, CMT test, black plate test, dairy cattle, subclinical mastitis.

Le but de notre recherche est de déterminer la dose limite de la toxicité aiguë de l’extrait aqueux (décoction vs. infusion) des feuilles d’Origanummajorana L. administré par voie orale en dose unique chez des souris Albinos Wistar.20souris blanches femelles de la race Albinos Wistarpesant entre 29.29g et 37.02g, récupérées de l’institut Pasteur d’ Alger en février 2022 et réceptionnées et élevés au laboratoire LURPHARTOX. Les animaux sont séparés en 3 lots: un lot recevant le décocté des feuilles de marjolaine (lot de décoction). Un autre lot gavé avec l’infusion de la même plante (lot d’infusion), et un dernierlot témoin.L’extraction par décoction des feuilles d’Origanummajoranaenregistre un rendement plus élevé par rapport à l’extraction par infusion. Ce qui pourrait nous orienter sur le choix de la méthode d’extraction et la richesse de chaque fraction en métabolites secondaires.L’administration par voie orale de dose unique limite d’extrait brut aqueux d’Origanummajorannaaux souris du lot d’infusionprovoque un effet notable sur le système nerveux avec des singes de convulsion et de léthargie pendent les 4 heures qui suit la mort. A l’autopsie,on remarque des lésions d’hépato-toxicitéimportantes et des lésions digestives. Selon les résultats obtenus, le pourcentage de mortalité est plus élevé pour le lot d’infusion comparativement au lot de décoction.Ainsi, la dose de 2000mg/kg de PV est la dose létale DL50. On peut donc dire la plante Origanummajoranaest toxique.

Hydatidosis is a parasitic disease caused by Echinococcus granulosus. It is also among the most prevalent zoonotic diseases with special importance for public health that causes drastic financial losses in both developed and developing countries. Among Algerian governorates, M’Sila region includes an important number of sheep flocks. Thus, an epidemiological survey was conducted on sheep hydatidosis during 5 months between December 2017 and April 2018 at three slaughterhouses of M’sila governorate, situated in municipalities of M’Sila, Boussaâda and Sidi Aissa. In parallel, an epidemiological investigation via interviews and questionnaire was conducted from March to April, 2018 on a sample of 46 sheep breeders located in M’Sila region. The questionnaire treated several risk factors (presence and deworming of dogs, informal slaughtering practices, fiability of preventive measures…etc.). Results showed a general prevalence of 24.80% among 9048 slaughtered sheep, and a seasonal prevalence higher in spring (42.02%) than in winter (21.65%) (p>0.05). Sheep of five to six years old and more are the most parasitized (p<0.0001). The lungs (38. 24%) and the livers (30.39%) were the most affected organs, while 31.24% of sheep were affected simultaneously in both organs (liver and lungs). Furthermore, females are more affected (97.99%) than males (2.01%) (p<0.0001). Keywords: Epidemiological survey, sheep hydatidosis, Echinococcus granulosus, slautherhouses.

Abstract The purpose of this study is to evaluate the effect of housing systems (free vs. tie-stall) and season (winter vs. spring) on the welfare of dairy cows through indices of cleanliness, leg health (straightness, hocks and knees), lameness score, body condition and milk production. This is to test the hypothesis that dairy cows in spring and free-stalls have a better quality of well-being than those kept in tie stalls in winter. For that, 299 dairy cows of the Holstein and Montbeliard breeds were selected from dairy farms in 6 communes of the Constantine governorate in eastern Algeria. The results showed that tie-stalled farms in winter were characterized by a lack of hygiene (P <0.001), with a stall cleanliness score of 7.62 and a frequency of 32.60% of dirty to very dirty cows. In the spring, the incidence of severe lameness does not exceed 9% in farms with tie stalls and more than 41% in mild lameness in housing with free stalls (P <0.001). Cows in tie stalls show a deviation of legs of 17° to 24° (57.97%). On the other hand, more than half of cows in free stalls show integumentary lesions (alopecia and swelling) of the carpal (60.25%) and tarsal joints (54.22%) (P <0.001). The percentage of fairly lean cows (score 2-2.5), housed in tie stalls, was significantly higher (18 to 44%) with a significantly low milk production (P <0.001). These results reflect a lack of comfort in tie-stall farms during winter which has an impact on dairy performance. Keywords: Welfare; dairy cows; housing type; season; Algeria.

A study was conducted in order to determine the prevalence and risk factors associated with abortion in ewes in the region of M’sila located in central Eastern of Algeria. A questionnaire was carried out to obtain informations about the occurrence of abortion, sheep housing conditions, vaccination, feeding and management practices, and whether the farmers kept other livestock.. This cross sectional study was conducted during 36 months (between 2016 and 2019). A total of 71 sheep flocks were visited. Among 8168 ewes, we recorded 734 (8.99%) abortions. The risk factor analysis using multivariable logistic regression showed association between abortion and vaccination against brucellosis (CI 95%= 2,76-1,35; p<0,001). There was association between flock size and abortion (CI 95%= 2,07-,36; p<0,001). Abortion decreased when dogs are owned (CI 95%= 0,36-0,84; p= 0.006), however, abortion increased with the presence of cats in farms (CI 95%= 1,24-2,8; p=0.003). There was a significant association between abortion and keeping goats (CI 95%= 1,18-2,40; p= 0.004), bovins (CI 95%= 0,3-0,68; p<0,001) and poultry CI 95%= 0,39-0,77; p= 0.001) in farms. We noticed a strong association between the occurrence of abortion and estrus synchronization, stillbirth occurrence, and feed supplementation (p<0.05). Identification of the causes of abortion is an important task to reduce foetal losses and to improve livestock productivity.

There was association between flock size and abortion (CI 95%= 2,07-,36; p<0,001). Abortion decreased when dogs are owned (CI 95%= 0,36-0,84; p= 0.006), however, abortion increased with the presence of cats in farms (CI 95%= 1,24-2,8; p=0.003). There was a significant association between abortion and keeping goats (CI 95%= 1,18-2,40; p= 0.004), bovins (CI 95%= 0,3-0,68; p<0,001) and poultry CI 95%= 0,39-0,77; p= 0.001) in farms. We noticed a strong association between the occurrence of abortion and estrus synchronization, stillbirth occurrence, and feed supplementation (p<0.05). Identification of the causes of abortion is an important task to reduce foetal losses and to improve livestock productivity. Keywords: Abortion, ewes, questionnaire, risk factors.

Abstract The purpose of this study is to evaluate the effect of housing systems (free vs. tie-stall) and season (winter vs. spring) on the welfare of dairy cows through indices of cleanliness, leg health (straightness, hocks and knees), lameness score, body condition and milk production. This is to test the hypothesis that dairy cows in spring and free-stalls have a better quality of well-being than those kept in tie stalls in winter. For that, 299 dairy cows of the Holstein and Montbeliard breeds were selected from dairy farms in 6 communes of the Constantine governorate in eastern Algeria. The results showed that tie-stalled farms in winter were characterized by a lack of hygiene (P <0.001), with a stall cleanliness score of 7.62 and a frequency of 32.60% of dirty to very dirty cows. In the spring, the incidence of severe lameness does not exceed 9% in farms with tie stalls and more than 41% in mild lameness in housing with free stalls (P <0.001). Cows in tie stalls show a deviation of legs of 17° to 24° (57.97%). On the other hand, more than half of cows in free stalls show integumentary lesions (alopecia and swelling) of the carpal (60.25%) and tarsal joints (54.22%) (P <0.001). The percentage of fairly lean cows (score 2-2.5), housed in tie stalls, was significantly higher (18 to 44%) with a significantly low milk production (P <0.001). These results reflect a lack of comfort in tie-stall farms during winter which has an impact on dairy performance. Keywords: Welfare; dairy cows; housing type; season; Algeria.

Abstract Hydatidosis is a parasitic disease caused by Echinococcus granulosus. It is also among the most prevalent zoonotic diseases with special importance for public health that causes drastic financial losses in both developed and developing countries. Among Algerian governorates, M’Sila region includes an important number of sheep flocks. Thus, an epidemiological survey was conducted on sheep hydatidosis during 5 months between December 2017 and April 2018 at three slaughterhouses of M’sila governorate, situated in municipalities of M’Sila, Boussaâda and Sidi Aissa. In parallel, an epidemiological investigation via interviews and questionnaire was conducted from March to April, 2018 on a sample of 46 sheep breeders located in M’Sila region. The questionnaire treated several risk factors (presence and deworming of dogs, informal slaughtering practices, fiability of preventive measures…etc.). Results showed a general prevalence of 24.80% among 9048 slaughtered sheep, and a seasonal prevalence higher in spring (42.02%) than in winter (21.65%) (p>0.05). Sheep of five to six years old and more are the most parasitized (p<0.0001). The lungs (38. 24%) and the livers (30.39%) were the most affected organs, while 31.24% of sheep were affected simultaneously in both organs (liver and lungs). Furthermore, females are more affected (97.99%) than males (2.01%) (p<0.0001). Keywords: Epidemiological survey, sheep hydatidosis, Echinococcus granulosus, slautherhouses, Algeria.

Foetal fluids are important in preventing mechanical shock to the developing foetus during entire gestation. Amniotic and allantoic fluids are actively involved in constant exchange of biochemical substance between foetus and maternal circulation. The estimation of composition of the foetal fluid is important for understanding foetal metabolism and diagnosis of pathological conditions during gestation. The purpose of the study was to determine the biochemical composition of the foetal fluids and to make comparison with the composition of the maternal plasma. A study was conducted in one hundred two gravid sheep uteri. The four stages of gestation as Stage – I (0-60 days), Stage - II (61-90 days), Stage - III (91-120 days) and Stage - IV (121-145 days) were identified based on crown anus length of the embryo/foetus. The amniotic and allantoic fluids collected from the gravid uteri of each group were subjected to biochemical analysis of glucose, cholesterol, triglyceride, total protein and urea. The levels of glucose and triglyceride in maternal plasma decreased significantly with advancement of pregnancy as well as in amniotic and allantoic fluids. In maternal plasma, levels of total protein and urea decresed significantly with advancement of pregnancy. There were however during the same period, a significant increase of total protein and urea concentrations in fœtal fluids. Cholesterol concentrations of fetal fluids were higher in advanced pregnancies. Key words: Amniotic fluid, Allantoic fluid, biochemical parameters, ewes, plasma.

L’analyse physico-chimique des aliments a montré que le concentré et le foin sont les plus riches en matière sèche, en matière organique et en parois cellulaires (NDF et ADF). Les fourrages verts sont les plus riches en matières azotées totales et en cendres totales, contrairement aux rebuts de dattes qui sont les plus lignifiés (ADL). La composition chimique des rations (0%R, 25%R, 50%R et 75%R) distribuées en fin de gestation est équivalente sauf pour la ration incorporée à 100% de rebuts de dattes qui présente le taux le plus élevé en ADF et en cellulose et le taux le plus faible en hémicellulose.

L’objectif de notre étude consiste à étudier l’impact du stade physiologique de la brebis sur les variations de quelques indices du profil biochimique (glucose, cholestérol, triglycérides, urée, créatinine et calcium) afin d’évaluer l’état métabolique et d’identifier lesquels de ces paramètres pourraient être utilisés comme indicateurs pour la prédiction du statut métabolique de la brebis au cours d’un cycle reproductif. Ce dosage combiné à la notation de l’état corporelle (NEC) des brebis permet de mieux connaître le statut nutritionnel de ces brebis. L’analyse des résultats a montré que le stade physiologique des brebis à une grande influence (P<0.05) sur la glycémie, la triglycéridémie, l’urémie, la Créatinémie et la calcémie; par contre, aucun effet significatif sur la cholestérolémie n’a pu être observé durant notre étude.

Objective: To evaluate the energetic profile of fetal fluids and to make comparisons of the concentrations of the constituents present with those in the maternal plasma. Methods: A study was conducted in 102 gravid sheep uteri. The four stages of gestation as Stage I (0–60 days), Stage II (61–90 days), Stage III (91–120 days) and Stage IV (121– 145 days) were identified based on the crown anus length of the embryo/fetus. The amniotic and allantoic fluids collected from the gravid uteri of each group were subjected to biochemical analysis of glucose, cholesterol and triglyceride. Results: The levels of glucose and triglyceride in maternal plasma were lower (P < 0.05) on late pregnancy as well as in amniotic and allantoic fluids. No significant variation (P > 0.05) of plasma cholesterol levels was detected between the sampling periods. Contrariwise, cholesterol concentrations of fetal fluids were higher in Stages III and IV of pregnancy when compared with the Stages I and II. Conclusions: The influence of pregnancy on the biochemical composition of fetal fluids was statistically significan

The study aimed to estimate the mineral status of the sheep breed Ouled Djellal depending on the physiological and nutritional state. The plasma level of some minerals was established to determine the effectiveness of digestion and assimilation of nutrients ewe during peripartum. The assessment of nutritional or metabolic state was highlighted by the physico-chemical analysis of the ration. The results showed that green fodder is richer in crude protein and ash mainly Mg, Na, K, Cu and Zn. The concentrate is the most energy food and that by its high content of organic matter and dietary fiber. By cons, hay despite its woody character, contains the highest levels of Ca and P. In sheep, a significant decrease (P <0.01) in serum calcium and magnesium is observed in late pregnancy. However, plasmatic phosphate increased significantly (P <0.01) in lactation phase. It should be noted that the plasma levels of sodium, potassium and chlorine does not show significant differences (P> 0.05) depending on the physiological stage. It is necessary to bring a correction of food with mineral intakes that are consistent with the critical periods of the sheep mitigating the metabolic requirements imposed.

The increase of the nutritive needs in ewes at the end of pregnancy, period where the feeding has a determinant action on the strength of lambs and on the preparation of ewes to lactating, emposes a food complementation particularly on extensive system. In order to determinate the effect of supplementation of date wastes on the variation of energetic and nitrogenic metabolism parameters, 45 pregnant ewes were distributed randomly in three groups; two experimental groups (25%R et 50%R) received during the last two months of pregnancy, a complementation after grazing based mainly on date wastes whereas the control group (0%R) does not receive any complementation. During the incorporation of date wastes at 25% mixed with concentrate, the females showed high plasmatic level of cholesterol (p<0.001) and triglycerides (p<0.001) and a low level of glucose (p<0.001) comparatively to the group 50%R and to the control group 0%R that did not vary significantly. However, the low plasmatic levels of total proteins (p<0.0001), of albumin (p<0.001) and of urea (p<0.01) were observed in females receiving a complementation of 50%. The date wastes remain protein’s deficient, which could be corrected by a simple protein intake making them interesting in their incorporation in animals feed. The replacement of date wastes to concentrate classically used would be of an economical interest

Objectif. The purpose of the present investigation was to determine the biochemical composition of the foetal fluids during differents stages of pregnancy Materiels and methods. The amniotic and allantoic fluids collected from gravid uteri of ewes in the beginning, mid and late pregnancy were subjected to biochemical analysis of glucose, cholesterol, triglyceride, total protein and urea. Results. The levels of glucose and triglyceride in fœtal fluids decreased significantly with advancement of pregnancy. The levels of total protein and urea incresed significantly with advancement of pregnancy. Cholesterol concentrations of fetal fluids were higher in advanced pregnancies when compared with the earlier gestations. Conclusion. It was concluded that the concentrations of glucose, cholesterol and triglycerides in foetal fluids of pregnant ewes may be changed with advancing the gestation stages. Based upon the evaluation of some metabolites, it may be possible to detect the early aberations in metabolism and thereby appropriate corrections could be made to overcome the metabolic disturbances during pregnancy.

Abstract The aim of this study was to investigate the impact of the péripartum period on the concentrations of the various blood parameters considered as good biological markers of the foeto-maternal metabolism of the ewes. The plasma concentrations of glucose, cholésterol, triglycerides, the total lipids, total proteins, urea, albumin, the globulins and creatinin were determined as well as minerals (Ca, P, Mg, Na, K, Cl and Fe) were measured. In parallel, the chemical and mineral composition of the feed ration was given. No significant variation (P>0.05) of plasma cholésterol, total lipids, total proteins and sodium levels was detected between the periods of taking away. While glucose, urea, albumin, calcium and magnesium levels were lower (P<0.05) on late pregnancy, triglycerides, potassium and phosphorus were significantly higher (P<0.05) during the same period. Moreover, the results of the study showed a significant increase (P<0,05) in albumin and the urea concentration during the post partum period. There were however during this period a significant reduction (P<0,05) in the plasma concentrations of creatinin, triglycerides, globulins, phosphorus, magnesium, chlore and potassium. Compared to the values of reference, the calcium concentration was noted very weak during all the probation period. Key words: profiles biochemical and mineral, ewe, péripartum, metabolism.

La teneur en cellulose brute de la paille est de 43,16 ± 0,36, elle est similaire à celle de Jarrige (1988) ; Chachoua (2005) ; Yakhlef et Triki (2007) qui sont respectivement 42% ; 42.94 ± 1.95% ; 41.35 ± 0.13% Sur le plan minéral, les analyses chimiques ont montré que la ration présente des valeurs acceptables en la comparant avec les normes bibliographiques établies par plusieurs auteures sauf, pour le calcium où nous avons noté des teneurs très faible dans le concentré et la paille qui sont respectivement 0.43 ± 0.57 et 0.91 ± 0.05 g/kg MS, plus faibles que celles de Jarrige (1988) à savoir 3.5 g/kg MS pour la paille et de 1.4 à 23 g/kg MS pour le concentré, et celles de Taghipoor et al. (2010) à savoir 0.9 g/kg de MS. Meziane (2001) a montré dans son étude que la paille est déficitaire en calcium (0.64 ± 0.04 et 0.73 ± 0.30 g/kg MS) avec un excès de phosphore (1.40 ± 0.30 et 2.50 ± 0.60 g/kg MS).

The aim of this study was to investigate the impact of the peripartum period on the concentrations of the various blood parameters considered as good biological markers of the foeto-maternal metabolism of the ewes. The plasma concentrations of glucose, cholésterol, triglycerides, the total lipids, total proteins, urea, albumin, the globulins and creatinin were determined as well as minerals (Ca, P, Mg, Na, K, Cl and Fe). In parallel, the chemical and mineral composition of the feed ration was determined. No significant variation (P>0.05) of plasma cholésterol, total lipids and sodium levels was detected between the sampling periods. While glucose, total proteins, urea, albumin, calcium and magnesium levels were lower (P<0.05) on late pregnancy, triglycerides, potassium and phosphorus were significantly higher (P<0.05) during the same period. Moreover, the results of the study showed a significant increase (P<0.05) in albumin and urea concentrations during the post partum period. There were however, during this period a significant reduction (P<0.05) in the plasma concentrations of creatinin, triglycerides, globulins, phosphorus, magnesium, chlore and potassium. Compared to the values of reference, the calcium concentration was very low during all the probation period.
