Effect of Mixed Storage of Hypsizygus Marmoreus Waste Substrate on Growth Performance, Slaughter Traits and Meat Quality Index on the Lambs
摘要
Abstract
This experiment was to study the impacts of mixed storage of hypsizygus marmoreus waste substrate on the lambs' growth performance,slaughter traits and meat quality index,and determine the suitable proportion of the mixing storage.32 healthy Bore crossbred goats with similar weight at nearly 3 months were chosen,and randomly divided into 4 groups of A,B,C and D,eight in each group.During the testing process,the diets were fed respectively containing 0％ (control group),16％,32％ and 48％ storage feed of hypsizygus marmoreus waste substrate for 60d.The results showed that the daily gain of the three experimental groups Ⅰ,Ⅱ and Ⅲ were respectively 9.52％,19.14％ and 11.29％ higher than the control (P＜0.05),and the daily profit of each lamb increased by 0.43,0.81 and 0.43 yuan,respectively,compared with the control.In the meanwhile,the slaughtering performances,such as the net meat rate,slaughter rate and eye muscle area,were not significantly different (P＞0.05).In the mutton experimentalgroup Ⅱ,the crude fat content was the highest and it was 20.1％ higher than the control (P＜0.05).The cholesterol levels were 16.6％,21.3％ and 27.2％ (P＜0.05)lower than the control,but other nutrients in the mutton were not significantly different.The contents of calcium,phosphorus,copper,manganese and selenium were higher than the control (P＜0.05),and as for the contents of iron and zinc,they were lower than the control (P＜0.05).Except the contents of serine amino acids and proline in mutton from experimental group Ⅲ,and the valine in experimental group Ⅰ were all lower than the control,the methionine was higher than the control (P＜0.05),other amino acids were not significantly different (P＞0.05).The contents of oleic acid in experimental groups Ⅱ and Ⅲ were 17.3％ and 13.5％ higher than the con trol(P＜0.05),and other fatty acids were of no significant differences (P＞0.05).The results indicate that it is effective to feed lambs with hypsizygus marmoreus waste substrate and residue resource stored after fermentation with an appropriate proportion of 32％.关键词
