Effect of barley worm meal on growth performance,meat quality,and economic benefits of finishing pigs
摘要
Abstract
The purpose of this experiment was to study the effects of different proportions of barley worm meal on the growth performance,meat quality,and economic benefits of finishing pigs,and to determine the optimal proportion of barley worm meal in finishing pigs production.In the experiment,120 healthy'Duroc × Landrace × Yorkshire'finishing pigs were randomly divided into four groups,with three replicates in each group and 10 pigs in each replicate.The control finishing pigs were fed a basal feed,and the experimental finishing pigs were fed the experimental diet containing 2.5％,5.0％,and 10.0％barley worm meal,respectively.The pre-trial period was one week,and the formal trial period was eight weeks.The results showed that the average daily gain of finishing pigs in the 5.0％barley insect meal group was significantly higher than that of the control group(P＜0.05),the carcass weight was significantly higher than that of the control group(P＜0.05),the pH24h value of muscle after slaughter was significantly higher than that of the control group(P＜0.05),and the drip loss was significantly lower than that of the control group(P＜0.05).The contentrations of glutamic acid,tyrosine,aspartic acid,arginine,threonine,leucine,total amino acids,total essential amino acids,and the umami amino acids in the longissimus dorsi muscle in the 5.0％and 10.0％barley worm meal groups were significantly higher than those in the control group(P＜0.05).The contentrations of leucine and arginine in the 2.5％barley worm meal group were significantly higher than those in the control group(P＜0.05).The 5％barley wormmeal group had the highest breeding profit,which was 11.74％higher than that of the control group.Studies has shown that an appropriate amount of barley insect meal can improve the growth performance,improve meat quality,and increase breeding profits of finishing pigs,and the addition amount of 5％is more appropriate.关键词
