“…STF was recorded in order to estimate its relationship with body reserves as an eventual alternative anatomical site (sternal region) to lumbar region to assess BCS. In goats, sternal region was found to provide greater precision on the prediction of body reserves than lumbar or caudal regions (Santucci and Maestrini, 1985;Morand-Fehr et al, 1989;Amaro and Caldeira, 1991). The proportion of remaining variation accounted for by STF on the prediction of TF and muscle weights, and on the percentage of TF in EBW (Table 12), showed that sternal region could eventually be an alternative site to evaluate BCS, although it has revealed to be a poorer predictor of body reserves than LJ.…”

Twenty eight non-lactating and non-pregnant adult Serra da Estrela ewes, ranging in body condition score (BCS) from 1 to 4 were used to study the relationships between BCS, live weight (LW), body composition and fat partition. Ewes were slaughtered and their kidney knob and channel fat (KKCF), sternal fat (STF) and omental plus mesenteric fat (OMF) were separated and weighed. Left sides of carcasses as well as the respective lumbar joints were then dissected into muscle, bone and subcutaneous (SCF) and intermuscular fat (IMF). The relationship between LW and BCS was studied using data from 1,396 observations on 63 ewes from the same flock and it was found to be linear. Regression analysis was also used to describe the relationships among BCS and/or LW and weights (kg) and percentages in empty body weight (EBW) of dissected tissues. The prediction of weights and percentages in EBW of total fat (TF) and of all fat depots afforded by BCS was better than that provided by LW. Only the weight of muscle and the percentage of bone in the EBW were more efficiently predicted by LW than by BCS. IMF represented the largest fat depot with a BCS of 1 and 2, whereas SCF was the most important site of fat deposition with a BCS of 3 and 4. Allometric coefficients for each fat depot in TF suggest that the fat deposition order in ewes from this breed is: IMF, OMF, SCF and KKCF. Results demonstrate that BCS is a better predictor than LW of body reserves in this breed and that LJ is a suitable anatomical region to evaluate BCS.

“…Lumbar joint (LJ), which is handled to assess BCS, was studied by others authors in order to predict the body composition of ewes (Delfa et al, 1989;Frutos et al, 1997) and goats (Amaro, 1990), as well as sternal fat in goats (Santucci and Maestrini, 1985;Morand-Fehr et al, 1989;Amaro and Caldeira, 1991).…”

“…Le maintien de l'état corporel est largement assuré pour les brebis ayant reçu une complémentation au pâturage aussi bien en caroube qu'en orge. Ceci s'explique sans doute par les bonnes valeurs énergétiques des deux compléments qui ont permis le maintien, voire une légère augmentation des réserves corporelles en énergie sous forme de lipides, les NEC étant corrélées avec la teneur en lipides de l'organisme entier (Morand-Fehr et al, 1990). effet du régime AlimentAire sur les performAnCes de reproduCtion des brebis Les paramètres de reproduction des brebis en fonction de la nature du complément énergétique sont présentés respectivement dans le tableau III.…”

La présente étude a pour but la substitution d'un concentré à base de caroube entière à un concentré à base d'orge. Elle a concerné cinquante brebis, réparties aléatoirement en deux lots: un lot témoin ayant reçu une complémentation à base d'une ration R1 constituée de 30 % son de blé et de 70 % d'orge en grains au flushing puis au steaming, et un lot expérimental qui a reçu un concentré R2 à base de 30 % de son de blé et de 70 % de caroube entière. L'impact de cette complémentation a été évalué par les notes d'état corporel (NEC) à la lutte et à la mise bas, les performances de reproduction ainsi que la croissance des agneaux.Les NEC ont été significativement identiques entre les deux lots à la lutte (3,33 vs. 3,48) et à la mise bas (2,87 vs. 2,94). De même, les vitesses de croissance ont été significativement similaires (p>0,05). Ainsi, les compléments énergétiques (orge vs. caroube) peuvent se substituer. Test of supplementation Ouled Djellal ewes by carob at flushing and steaming inforMación Cronología del artículo. Recibido/suMMarYThis study aims to substitute a concentrate containing whole carob food to the concentrate containing barley. It concerned fifty ewes, randomly divided into two groups : a control group that received supplementation based on a ration R1 containing wheat bran (30 %) and barley grains (70 %) in the flushing and steaming, while experimental group received at the same time a ration R2 containing wheat bran (30 %) and whole carob (70 %). The impact of this complementation was evaluated by body condition score at mating, before lambing, reproductive performance and lamb growth.The body condition scores in breeding were significantly identical between the two groups (3.33 vs. 3.48) and at lambing (2.87 vs. 2.94). Similarly, growth rates of lambs were not significantly different (p>0.05). Thus, the energy supplements (barley vs. carob) can be substituted. additional keYwords

Estimation de la teneur en lipides des chèvres laitières par diverses méthodes informant sur le métabolisme lipidique ou l'état corporel

Abstract: Summary ― In 10 lactating goats, the body condition score was well correlated (r = from 0.80 to O.B3) to the empty body lipid content measured chemically after slaughtering. A good evaluation (r = 0.83) can be obtained from the total fatty acid content of oleic acid in milk.
