【摘要】 为了解加系母猪经过国内饲养管理后,其后代的采食行为和生产性能情况,对其采食行为和饲料转化率进行测定。利用全自动种猪生产性能测定系统(FIRE),对加系杜洛克(5头)、大白(32头)和长白(10头)进行日采食量、日采食次数、每次采食时间、体重、平均日增重和料重比等数据进行测定和分析。结果表明:体重在30~100kg,日龄在63~158d范围,杜洛克、大白和长白平均日增重分别是0.99kg、0.95kg和0.97kg;料重比分别是2.34、2.33和2.42。不同品种母猪及个体间的采食行为存在差异,每次采食时间主要分布在3-8min,日采食次数在7~21次,每次采食时间与日采食次数呈反比。每次采食时间、日采食次数及日采食量对平均日增重和料重比具有一定的影响。更多还原

【Abstract】 In order to master the production performance of the feeding behaviors and production performance of the Canadian sows offspring,the feeding behaviors and feed conversion rate were measured.The data of Duroc(5),Large white(32)and Landrace(10)including daily feed intake,number of visits per day,time spent eating per visit,body weight,average daily gain and feed conversion rate of the cows,were measured and analyzed by using the automatic pig production performance measurement system(feed intake recording equipment).The results showed that,the average daily gain of the Duroc,Large white and Landrace were 0.99 kg,0.95 kg and 0.97 kg,and the feed conversion rate of them were 2.34,2.33 and 2.42,whose body weight were from 30 to 100 kg and date was from 63 to 158 d,respectively.There were significant differences in the feeding behavior among different varieties of strain sows and individuals.The time spent eating per visit was mainly distributed at 3-8 min,and the number of visits per day was between 7-21 times.The time spent eating per visit was inversely proportional to the number of visits per day.Daily feed intake,the number of visits per day,and time spent eating per visit have a certain impact on average daily gain and feed conversion rate.更多还原
