Abstract

ABSTRACT The objective of this study was to assess the chemical composition and in vitro digestibility of residues of five pearl millet varieties and to investigate their effect on the performance of sheep. Thirty castrated male Bali-Bali sheep were randomly assigned to five treatments. Four dual-purpose millet varieties and one local variety-Somno were used. Sheep were fed ad libitum for 90 days with the stover of five millet varieties, complemented with cowpea hay. Stover of varieties ICMV167005 and ICMV167002 showed a tendency for a higher nitrogen content (1.0%) and in vitro digestibility (51.3% and 51.8%, respectively) compared to stover of other varieties. Significant differences were observed in average daily live weight gain. The animals fed with stover of the variety ICMV167005 in their diet had higher average daily live weight gain compared with others. We conclude that ICMV167005 is a promising variety for improving the productive performance of sheep.

西非萨赫勒地区不同珍珠粟品种秸秆化学成分和体外消化率评价及其对绵羊生产性能的影响

摘要本试验旨在研究5个珍珠粟品种的化学成分和体外消化率，并探讨其对绵羊生产性能的影响。30只阉割的雄性Bali-Bali羊随机分为5个处理。使用了四种两用小米品种和一种当地品种- somno。试验用5个谷子品种的秸秆和豇豆干草进行90 d的自由饲喂。与其他品种相比，ICMV167005和ICMV167002的含氮量(1.0%)和体外消化率(51.3%和51.8%)均有较高的趋势。在平均日活增重方面观察到显著差异。饲粮中饲喂ICMV167005品种秸秆的动物平均日活增重高于其他品种。综上所述，ICMV167005是一个很有希望提高绵羊生产性能的品种。
