摘要:
为研究在饲粮中补饲非常规饲料对山羊屠宰性能、血液生化指标以及肉品质的影响，选择28只体质量为（21.27±2.67）kg的波杂羊（波尔山羊×徐淮山羊），随机分成4组，分别饲喂4种不同饲粮，以高精料A组（精料所占比例70%）为对照组，饲粮B组、C组和D组为试验组，在高精料A基础上补饲非常规饲料，其中B组精料所占比例50%，C组精料所占比例20%，D组精料所占比例0。精料由玉米、豆粕、麸皮和小麦为主要原料配制，非常规饲料来源于大豆皮、橘子皮、醋糟、喷浆玉米皮。试验羊单独饲喂，在60 d后进行屠宰。结果表明：1）C组和D组的山羊屠宰率均显著高于A组和B组（P<0.05），4组饲粮处理的山羊眼肌面积差异不显著（P>0.05）；2）C组山羊血液中葡萄糖含量显著高于A组和B组（P<0.05），A组、B组和D组的山羊血液中尿素氮含量均显著高于C组，4组饲粮处理山羊血液中低密度脂蛋白胆固醇、高密度脂蛋白胆固醇以及总胆固醇的含量差异不显著（P>0.05）；3）4组饲粮处理的山羊宰后45 min、24 h的pH值及屠宰后12 h、24 h、48 h的滴水损失、蒸煮损失以及山羊肉的L*、a*、b*、弹性和内聚性差异不显著（P>0.05），A组羊肉的剪切力、硬度和咀嚼性显著高于C组和D组；4）4组饲粮处理的山羊肉中水分、干物质差异不显著（P>0.05），A组山羊肉中粗灰分显著高于C组和D组（P<0.05），C组山羊肉中有机物显著高于A组（P<0.05），4组饲粮处理山羊肉中粗蛋白差异不显著（P>0.05），C组和D组的山羊肉中粗脂肪含量均显著高于A组和B组（P<0.05）。说明，在本试验研究背景下，在高精料中补饲非常规饲料，可以提高山羊屠宰性能以及肉品质，并且对血液生化指标未产生不良影响，其中以精料所占比例20%（饲粮处理C）具有较好的改善效果。
Abstract:
The experiment was conducted to investigate the effects of supplementary feeding with un-conventional feeds on slaughter performance, blood biochemical index and meat quality of goats (Boer goats × Xuhuai goats). A total of 28 healthy goats with an average body weight of (21.27±2.67) kg were randomly allotted to four groups, with seven replicates per group. Goats were fed four kinds of diets, with high concentrate as the control group (proportion of concentrate 70%), diet B, diet C and diet D feeding with un-conventional feeds, which were used as the experimental diets. Diet B contained 50% concentrate, diet C contained 20% concentrate, diet D contained 0 concentrate. The un-conventional feed was from soybean hulls, orange peel, vinegar, the corn husk of spray. Concentrate made from corn, soybean meal, bran and wheat. Sheep were fed individually and slaughtered at the end of the experiment (60 days). The results showed dressing percentage under the treatment of diet C and diet D was significant higher than that under the treatments of diet A and diet B (P<0.05), the four treatments had no effect on the loin-eye area (P>0.05). The content of glucose under the treatment of diet C was significant higher than that under the treatments of diet A and diet B (P<0.05), diet A, diet B and diet D was significant higher than that under the treatment of diet C (P<0.05). The contents of HDL-C, LDL-C and total cholesterol in goats under four different treatments had no difference (P>0.05). There was no difference on the pH45 min, pH24 h drip loss, at 12 h, 24 h and 48 h, cooking loss, a* (redness), b* (yellowness), L* (lightness), springiness and cohesiveness under four different treatments(P>0.05), the shear force, hardness and chewiness under the treatment of diet A were significant higher than under four different treatments diet C and diet D (P<0.05). There was no difference on the mutton water and dry matter under four different treatments(P>0.05), the crude ash under the treatment of diet A was significant higher than that under the treatments of diet C and diet D (P<0.05), the content of organic matter under the treatment of diet C was significant higher than that under the treatment of diet A (P<0.05), the content of crude protein in goats under four different treatments had no difference (P>0.05), the content of crude fat under the treatments of diet C and diet D was significant higher than that under the treatments of diet A and diet B (P<0.05). It was concluded that supplementary feeding the un-conventional feeds in high concentrate, could improve the goat slaughter performance and meat quality, and it hadn’t adverse effects on blood biochemical index， the treatment of diet C (concentrate accounted for 20%) had a better improvement.
