摘要
为研究饲料中添加不同比例的玉米柠檬酸渣对育肥猪增重效果的影响,试验选取40头60 kg左右的育肥猪,采用单因素完全随机分为5个处理组,每个处理组8头猪。对照组饲喂“玉米+豆粕”型基础日粮,4个试验组分别饲喂含有3%、6%、9%和12%的玉米柠檬酸渣饲粮。结果表明:(1)4个试验组与对照组平均日采食量差异不显著(P>0.05);(2)A组、B组平均日增重、料肉比与对照组差异不显著(P>0.05),A组、B组平均日增重分别比对照组高0.77%、1.24%(P>0.05),料肉比较对照组分别低1.63%、2.29%(P>0.05);(3)C组、D组平均日增重、料肉比与对照组差异显著(P<0.05),C组、D组平均日增重分别比对照组低2.73%、4.39%,料肉比较对照组分别高3.59%、4.9%(P<0.05);(4)A组、B组育肥猪每增重1|kg所需的饲料成本分别降低2.52%、4.4%。说明在日粮中添加一定量的玉米柠檬酸渣,对育肥猪生长性能有一定的促进作用,养殖经济效益显著,其中以6%的添加量较为适宜。
In order to study the effect of adding different proportions of corn citric acid residue in feed on the weight gain of fattening pigs,40 fattening pigs of about 60 kg were selected in the experiment,and were completely randomly divided into 5 treatment groups with 8 pigs in each treatment group by single factor.The control group was fed corn-soybean meal basal diet,and the four experimental groups were fed diets containing 3%,6%,9% and 12% corn citric acid residue,respectively.The results showed that:(1)there was no significant difference in average daily feed intake between the four experiment groups and the control group(P>0.05);(2)the average daily weight gain and feed meat ratio of group A and B were not significantly different from the control group(P> 0.05).The average daily weight gain of group A and B was 0.77% and 1.24% higher than that of the control group respectively(P>0.05).The feed meat ratio of group A and B was 1.63% and 2.29% lower than that of the control group(P>0.05).(3)the average daily weight gain and feed meat ratio in group C and D were significantly different from those in the control group(P<0.05).The average daily weight gain in group C and D was 2.73% and 4.39% lower than that of the control group,and the feed meat ratio of group C and D was 3.59% and 4.9% higher than that of the control group(P<0.05).(4)the feed cost of fattening pigs in group A and Group B decreased by 2.52% and 4.4% respectively for each 1 kg gain.The results showed that adding a certain amount of corn citric acid residue to the diet had a certain promoting effect on the growth performance of fattening pigs,and the economic benefit of breeding was significant,among which 6% was more suitable.
