马铃薯淀粉浓缩蛋白复合饲料对良凤花肉鸡生长性能和屠宰性能的影响
Study on Effect of Compound Protein Feedstuff of the Highly Concentrated Potato Starch on Growth and Slaughter Performance of Liangfeng Chicken
摘要
Abstract
180 one-day-old Liangfeng chicken were selected and randomly divided into four groups,the chicken were fed with the daily ration for 42 days,in which the soybean meal was substituted with the different concentration of potato protein. The growth and slaughter performance of chicken was studied. Compared with the control,all trial groups of daily gain of the starter and finisher were significantly high.The daily gain of the trial groupⅢwas signif-icantly higher than the trial groupⅠwhich was same as the trial groupⅡin the starter. Apparently,the trial groupⅢ was also the highest in the finisher. Feed intake was not significant between trial groupⅠand groupⅡin star-ter higher. In finisher and all period, trial group Ⅰ and trial group Ⅱwas significantly different. Group Ⅲ was much higher than group I andⅡin every period. For feed-gain ratio,the trial groups was lower than the control in the starter,and the trial group Ⅲwas the lowest in all groups in the starter and finisher. After a slaughter trial was performed,weight,carcass percentage,eviscerated percentage,semi-eviscerated percentage,leg muscle percentage and chest muscle percentage was not apparently different between the trial groups and the control. In pH trial,sig-nificant differences were found between the control and trial group Ⅰ. Besides,the control group had a slight dif-ferent with the trial group Ⅱ and Ⅲ. In the shear force,the trial group Ⅰ was not significantly different with the control and the trial groupⅢwas lower than other groups. The results showed that,compared with control group,it was statistically significant for the daily feed intake,daily gain increased,and feed conversion rate decreased that chicks was fed with the daily ration including 4% -12% potato protein.关键词
