Effects of Replacing Some Corn and Soybean Meal with Bran or Alfalfa Pellets on Growth Performance,Serum Biochemical Indexes and Economic Benefits of Finishing Pigs
摘要
Abstract
The aim of the experiment was to study the effects of replacing part of corn and soybean meal with bran or alfalfa pellets on the growth performance,serum biochemical indexes and economic ben-efits of finishing pigs.A total of 240 healthy Duroc× Landrace × Yorkshire crossbred pigs,with an average weight of 36.74+0.18 kg and around 104 days of age,were randomly divided into three groups,namely,the control group,the bran group and the alfalfa group,with five replicates per group and 16 pigs(half male and half females)per replicate.The control group was fed a corn-soybean meal basal diet based on the NRC(2012)nutritional standards,and the experimental group was fed 10％bran or alfalfa pellets instead of corn and soybean meal in the basal diet.The pigs were pre-fed for 7 days and then formally fed for 96 days.The results showed that:(1)There were no significant differences in initial and final body weights a-mong the three groups(P＞0.05).Compared with the control group,both the bran group and the alfalfa group had significantly increased average daily feed intake of the finishing pigs from 61～96 d and from 0～96 d(P＜0.05).The feed-to-meat ratio of the finishing pigs from 34～61 d were significantly increased(P＜0.05).(2)There were no significant differences in live weight,carcass weight,slaughter rate and back-fat thickness among the groups(P＞0.05).(3)Compared with the control group,the gluten group exhibi-ted significantly increased activities of alanine aminotransferase and glutamine aminotransferase as well as the concentration of albumin(P＜0.05);the activity of alkaline phosphatase in alfalfa group was signifi-cantly increased(P＜0.05);and the content of high-density cholesterol in the serum of the two experimen-tal groups was significantly increased(P＜0.05).(4)For economic benefits,the average profit per pig in the bran group was 27.63 yuan higher than that in the control group,and the average profit per pig in the alfalfa group was 38.38 yuan higher than that in the control group.These results indicate that replacing corn and soybean meal in some of the basal diets with 10％bran or alfalfa pellets can improve the growth performance of finishing pigs,and have no effect on carcass traits,both of which significantly increased the content of high-density cholesterol in the serum of finishing pigs,and were able to reduce the feed cost of finishing pigs,and improve the breeding efficiency.关键词
