Abstract

The study's objectives are to determine the impact of adding date pits to pregnant and lactating ewes' diets on milk production and to value agro-industry byproducts. Twenty-four pregnant Algerian "Ouled Djellal" ewes were split into two groups at random. A meal consisting of 500g of concentrate and 1.5 kg of vetch-oat hay was given to the first group (75 CON). In addition to 500g of concentrate, the animals in the second group (75MIX-CON) were fed a diet consisting of 1.5 kg of vetch-oat hay and date pits at a ratio of 46.7 to 53.3%. The concentration is made up of 50% barley grains and 50% wheat bran. The lambs' live weight, the volume of milk, the physico-chemical analysis of the ration's feed components (dry matter, organic matter, mineral matter, crude protein, and crude fiber), and the physico-chemical analysis of the milk (fat and protein levels) were the main objectives of the study. The results of the statistical analysis (Minitab16) showed that the growth performance of the lambs in the experimental and control groups differed significantly (P=0.05) (147.2 vs. 185.73 g/day). With an average milk output of 0.59 l/d compared to 0.47 l/d, the experimental group's milk production significantly increased. In conclusion, it appears that supplementing females with date pits at the end of gestation improves both the mothers' dairy performance and the lambs' growth performance.
