【摘要】：本实验以817肉仔鸡为试验动物,研究在日粮中添加不同水平的中草药饲料添加剂观察其对肉鸡生产性能、胴体品质、肉质风味的影响。实验采用单因素多水平设计,分两批屠宰,1~35天设19个处理,1~48天设21个处理。其中有一个空白对照组和两个分别加入50mg/kg、12.5mg/kg抗生素添加剂组。通过实验数据证明得出:部分实验所用中药添加剂能提高817肉鸡屠宰指标。中草药饲料添加剂在滴水损失和水分含量实验中各组内差异不明显,且与对照组和抗生素组比较无显著差异(P0.05)。实验所用部分中药添加剂能改善817肉鸡的蒸煮损失和肉质嫩度,但均能提高817肉鸡脂肪和蛋白含量。在对不同组817肉鸡胸肉中的核苷酸含量检测结果表明:35天肉鸡日粮中添加中草药添加剂,除组17外均不同程度地提高了肌肉中的核苷酸含量,实验表明实验所用中药添加剂均能提高35天817肉鸡肌肉中核苷酸的含量。在对48天肉鸡胸肌中核苷酸(IMP和GMP)含量方面实验中,组方2发酵后按0.3%的比例对核苷酸(IMP和GMP)改善极显著(P0.01)。其他各组与对照组和抗生素组相比无明显差异。从上述结论结果来看,组10(0.3%配方四)对817肉鸡的生产性能、胴体品质和肉质风味的影响最为显著,最适宜当作中草药饲料添加剂代替抗生素饲料添加剂在实际生产中应用。
[Abstract]:In this experiment, 817 broilers as experimental animal, the study of Chinese herb feed additives with different levels in the diets were observed on production performance, carcass quality, meat quality and flavor. The effect of using multi level single factor design, two batches of slaughter, 1~35 day 19, 1~48 days with 21 treatments. One control group and two 50mg/kg were added, 12.5mg/kg antibiotic additive group. Through the experimental data show that part of the traditional Chinese medicine additive can improve 817 broiler slaughter index. Chinese herbal feed additive groups in drip loss and water content in the experiment was not significantly different, and compared with the control group and the antibiotic there was no significant difference (P0.05). The experiment uses part of traditional Chinese medicine additive can improve the cooking loss and 817 broiler meat tenderness, but could increase 817 broiler fat and protein content. In different groups of 817 meat The nucleotide content detection results showed that the addition of chicken breast in the Chinese herbal medicine additive in broiler diets for 35 days, in addition to the group 17 increased different nucleotide content in muscle, the results show that the experimental use of traditional Chinese medicine additive could improve the content of 35 days and 817 nucleotides in the muscle of chicken. In 48 days of nucleotide in broilers the pectoral muscles (IMP and GMP) content in the experiment, 2 after fermentation prescription according to the proportion of 0.3% of nucleotide (IMP and GMP) improved significantly (P0.01). There was no significant difference between other groups and the control group and the antibiotic group. Conclusion from the above results, group 10 (0.3% formula four) production performance of 817 broiler, affect carcass quality and flavor of meat is the most significant and most suitable as a feed additive of Chinese herbal medicine instead of antibiotic feed additives in actual production.
