Milk production and body weight changes were studied in the Algerian Rembi sheep breed. Thirty two lactating ewes, 3 to 5 years old, were divided into two groups of heavier (HG) and lighter (LG) body weights. The average weights were 56.6±2.4 and 47.5±3.9 kg for HG and LG groups, respectively. Milk yield was measured using oxytocin plus hand milking method and ewes were weighed weekly. Daily and total milk yield were 587±200g and 63.9 kg; 527±202g and 57.3 kg, for heavy and low ewes, respectively, with 10.3% difference (p>0.05), in spite of a highly significant difference in means of live weights between both groups (p<0.001). During the first 7 suckling weeks, mean weight loss for HG and LG groups was 6.3% (p<0.001) and 6.9% (p<0.05), respectively. Body weight variations during the whole suckling period were not important in both groups; hence, ewes recovered almost all the initial live weight in the late experiment period. © iForest – Biogeosciences and Forestry.
