The objective of this work was to study the effect of the incorporation of argane by-products (meal and pulp) in ewe's diet on the production and quality of milk and the performance of lambs in the lactation phase. Twenty ewes were divided into two equal groups. The first one has been fed with argane by-product diet (AD), and the second with a control diet (CD). The results showed an improvement in milk production with an average of 26.3% for AD compared with the CD group. AD group lambs showed a significant difference (p < 0.05) compared with the CD group during lactation phase. The ash and protein levels were not affected by treatments; however, fat, lactose, density, and fusion point content show more fluctuations for both treatments (p < 0.05). The physicochemical parameters of sheep milk showed high (p < 0.01) to very high (p < 0.001) significant change, along the lactation weeks. Except the Zn which showed no significant difference (p > 0.05), the mineral composition of both milks (Na, K, Ca, Mg, P, and Fe) was significant (p < 0.05). It is concluded that, in terms of performances, argane by-products could replace the conventional diet for ewes without substantial detrimental effects. Therefore, argane by-product could be used as a cost-effective feed for sheep in dry areas.
这项工作的目的是研究在母羊日粮中添加阿甘油副产品（粕和果肉）对产奶量、奶品质以及泌乳期羔羊性能的影响。将20只母羊平均分为两组。第一组饲喂阿甘油副产品日粮（AD），第二组饲喂对照日粮（CD）。结果表明，与CD组相比，AD组的产奶量提高，平均提高了26.3%。AD组羔羊在泌乳期与CD组相比有显著差异（p < 0.05）。处理对灰分和蛋白质水平没有影响；然而，两种处理的脂肪、乳糖、密度和熔点含量波动更大（p < 0.05）。绵羊奶的理化参数在泌乳周期间显示出高（p < 0.01）到非常高（p < 0.001）的显著变化。除锌无显著差异（p > 0.05）外，两种奶的矿物质组成（钠、钾、钙、镁、磷和铁）均有显著差异（p < 0.05）。得出的结论是，在性能方面，阿甘油副产品可以替代母羊的传统日粮而不会产生实质性的有害影响。因此，阿甘油副产品可以用作干旱地区绵羊的经济高效饲料。
