The effect of peanut meal on the growth performance,meat quality,and economic benefits of fattening pigs
This experiment aims to investigate the effects of Peanut Meal(PM)on the growth performance,meat quality,and economic benefits of fattening pigs. Method:120 healthy and disease-free pigs with an initial weight of(87.15±2.63) kg were selected and randomly divided into 4 groups,each with 3 replicates and 10 pigs per replicate. The CON group used a basic diet,while the other three groups used 20％(20 PM group),40％(40 PM group),60％(60 PM group)peanut meal and other nitrogen to replace soybean meal in the basic diet. The experiment lasted for 30 days. Result:(1)Compared with the CON group,the average daily weight gain of the 20 PM group significantly increased by 9.42％(P<0.05),and the feed to weight ratio significantly decreased by 8.88％(P<0.05);The average daily weight gain of the 40 PM group significantly increased by 11.97％(P<0.05),while the feed to weight ratio significantly decreased by 9.92％(P<0.05).(2)Compared with the CON group,the drip loss and shear force in the 60 PM group were significantly increased(P<0.05).(3)The gross profit of CON group,20 PM group,40 PM group,and 60 PM group were 28.54 yuan,67.32 yuan,74.61 yuan,and 32.17 yuan,respectively. Conclusion:Peanut meal has a medium to low substitution level(20％～40％)for soybean meal,which improves the growth performance of fattening pigs. But the high substitution level of peanut meal for soybean meal(60％)reduces the meat quality of fattening pigs. From the perspective of economic benefits alone,the suitable substitution level of peanut meal for soybean meal is 40％.
