Abstract
This study aims to assess the impact of adding yeast and date waste to meals on the biochemical parameters related to minerals in sheep at the end of gestation and during lactation, as well as to valorize by-products of the agro-industry. Thirty pregnant ewes belonging to the "Ouled Djellal" breed of Algerian sheep were split into five groups at random. Wheat straw (1 kg/sheep) was given as roughage to every ewe. In addition to wheat straw, the control group, designated as T0, was given a ration consisting of 500g of concentrate. A combination of date waste (DW) and concentrate was supplied to the first group (T1) at a ratio of 8.33% to 25%. the second group (T2) received 8.33% concentrate and 25% date waste. The third group (T3) was given 2 grams of yeast per ewes along with an equal proportion of concentrate and DW (16.6% to 16.6%). Without yeast, the fourth group (T4) was given the same ration as the third group (T3). The blood metabolic profile of nursing ewes and the physico-chemical analysis of the ration's dry matter, organic matter, mineral matter, crude protein, and crude fiber were both carried out. Three biochemical factors were examined: magnesium, calcium, and phosphorus. Significant variations (P<0.05) were noted in the levels of biochemical parameters, predominantly related to the ratios of date waste and yeast supplementation at the conclusion of gestation and during lactation. Serum levels were lower in ewes fed the T1, T2, T3, and T4 meals than in the T0 control group. Nonetheless, these values persisted within the physiologically permissible limits, suggesting that ewes have adapted to this byproduct. The metabolic profile of pregnant ewes seems to benefit from the feeding of yeast and date waste. Thus, it may be said that date waste, a locally available sustainable resource, could be valued and given to sheep in place of concentrate, saving money on costly imported barley.
