Analysis of the effect of Berkshire hybrid introduction on the growth and fattening traits of Suzi pigs
摘要
Abstract
In order to understand whether the growth and fattening traits of Suzi pigs were affected by hybridization introduction of Berkshire pigs,68 different types of Suzi pigs were selected with an initial body weight of around 30 kg,in the experiment.The production performance of these pigs was measured using an automatic breeding performance measurement system by batch.130 700 pieces of effective feeding and weighing data were obtained.In-depth analysis of these data showed that Suzi pigs with different levels of Berkshire bloodline had different day ages in reaching relevant body weight.For the age days at 60 kg body weight and age at 90 kg body weight,Suzi pigs possessing 50%Berkshire bloodline had the biggest age period,significantly bigger than that of Suzi pigs with no Berkshire bloodline(P＜0.05).Secondly,Suzi pigs with different levels of Berkshire bloodline also had different daily gains.During the 30-60 kg growth stage,the daily gain of Suzi pigs containing 25%Berkshire bloodline and Suzi pigs containing none Berkshire bloodline were significantly higher than that of Suzi pigs containing 50%Berkshire bloodline(P＜0.05).During the 30-90 kg and 30-110 kg growth stage,the daily gain of Suzi pigs containing none Berkshire bloodline was the highest,significantly higher than that of Suzi pigs containing 50%Berkshire bloodline(P＜0.05).Lastly,Suzi pigs with different levels of Berkshire bloodline also had different feed conversion ratios.During the 30-90 kg and 30-100 kg growth stage,the feed conversion ratio of Suzi pigs containing 50%Berkshire bloodline was the lowest,and it was significantly lower than that of Su-zi pigs containing 25%Berkshire bloodline and Suzi pigs containing no Berkshire bloodline(P＜0.05).In short,the introduction of Berk-shire bloodline through hybridization did not significantly improve the growth rate of Suzi pigs,but significantly promoted their feed conversion ratio.And Suzi pigs containing 25%Berkshire bloodline showed relatively balanced growth performance and enjoyed prior breeding in the fu-ture.关键词
