热应激下猪生长性能及繁殖能力分析
Growth Performance and Reproductive Ability of Pigs under Heat Stress
摘要
Abstract
In order to explore the characteristics of growth performance and reproductive ability of fattening pigs and sows under heat stress and their relationship,this study collected and compiled the related literature of pig growth performance and reproductive capacity published from 2000 to 2021.The discrete coefficient was used to test the discreteness of the data,and Pearson coefficient was used for correlation analysis.The results showed that heat stress had the most significant effect on the average daily feed intake(ADFI)of fattening pigs(P<0.01).When temperature was 18.50-28.40℃and relative humidity was 67.00%-84.00%,feed utilization rate was the highest,and the ra-tio of feed to gain reached 2.20-2.86.Among the effects of heat stress on reproductive performance of sows,the weight of weaned piglets was the most significant(P<0.01),and the maximum weight of weaned piglets was maintained at 6.32-6.90 kg when temperature was 19.00-25.00℃and relative humidity was 45.00%-85.00%.It is suggested that reasonable environmental regulation should be carried out in the optimal range of temperature and humidity to reduce the adverse effects of heat stress during pig breeding.关键词
