不同地理条件和营养水平对龙陵黄山羊生产性能的影响
Effect of Different Geographical Environments and Nutrition Levels on Growth Performance of Longling Yellow Goat
摘要
Abstract
The aim of this study was to explore the effects of the suitable geographical environment and nutritional level on the growth of Longling yellow goat. Animal experiments were carried out simultaneously in three goat farms with different geographical environment. The Longling yellow goats of each goat farm were assigned to 2 treatments with 2 or 3 replications per treatment and 6-8 goats per replicate. The treatments were fed low-energy low-protein diet or high-energy high-protein diet. The experiment was conducted for 90 days. Under the low-energy low-protein diet condition,the average daily gain(ADG),average daily intake of concentrate and average daily intake of dry matter of middle altitude group and low altitude group were significantly higher than those of high altitude group(P<0.01). Middle altitude group showed the lowest feed to gain ratio,compared with high altitude group (P<0.05)and low altitude group(P<0.01). The concentrate to gain ratio of low altitude group was significantly higher than those of high altitude group(P<0.01)and middle altitude group(P<0.01). Under the high-energy high-protein diet condition,the ADG, average daily intake of concentrate and average daily intake of dry matter of middle altitude group and low altitude group were significantly higher than those of high altitude group(P<0.01). In conclusion,Longling yellow goat in the middle altitude and low altitude areas(average annual temperature 20℃)showed a better growth rate than in high altitude area. High-energy high-protein diet is beneficial to improve the growth performance of Longling yellow goat.关键词
