Effects of Different Nutritional Levels of Diet on the Growth Performance and Organ Indexes in Fattening Hainan Black Goats
摘要
Abstract
This experiment was conducted to investigate the effect of different nutritional levels of concentrate supplementation on the growth performance and organ indexes in Hainan Black goats of three-month-old. The experiment was a 2×3 factorial design. Twenty four lambs with the weight of (10. 56 ± 1. 28)kg were randomly assigned to 6 treatments with 4 replicates in each treatment of 1 lamb per replicate. The 6 treatment groups were shown as follows:concentrate supplementation with 15% CP and 11. 72 MJ/kg DE,15% CP and 12. 55 MJ/kg DE,15% CP and 13. 39 MJ/kg DE,17% CP and 11. 72 MJ/kg DE,17% CP and 12. 55 MJ/kg DE,and 17% CP and 13. 39 MJ/kg DE. The experiment lasted for 90 days. The results showed that different crude protein levels in concentrate supplementation had significant effects on average daily gain (ADG) (P<0. 05). Goats fed concentrate supplementation with 17% crude protein had the higher ADG and the lower feed intake/ body gain (F/ G) (P<0. 05). Different crude protein and digestive energy levels had no significant effects on organ indexes of heart, liver, spleen,lung,kidney and stomach in goats (P>0. 05). The organ indexes of intestine reduced with increasing digestive energy levels in concentrate supplementation (P<0. 05). The results demonstrated that different crude protein and digestive energy levels in concentrate supplementation had significant effects on ADG,F/G and organ indexes and weight of intestine for Hainan Black of three-month-old, while for other organ indexes had no effects (P>0. 05).关键词
