摘要: 研究旨在比较大额牛和婆罗门杂交后代(GBF1)与云岭牛肉品质,评估大额牛杂交利用潜能。选择年龄相近、性别相同的GBF1牛和云岭牛进行育肥、屠宰,采集100个肉样冻存。以肉质较好的云岭牛肉为对照,检测GBF1牛肉的剪切力、失水率、系水力、蒸煮损失。结果表明,GBF1牛肩峰剪切力显著高于云岭牛(P< 0.05),其他部位肉剪切力两品种间没有显著差异(P> 0.05)。GBF1牛10个部位肉的平均剪切力、失水率、蒸煮损失分别为3.50 kg、24.15%、27.56%,低于云岭牛;平均系水力64.60%,高于云岭牛,但差异均不显著(P> 0.05)。由此可知,GBF1牛肉品质与云岭牛相似,且均较好。

Abstract: This study was aimed to compare the meat quality of Gayal×Brahman (GBF1) cattle and Yunling cattle, evaluate the potential of crossbreeding utilization of Gayal.GBF1 cattle and Yunling cattle which had same ages and same gender were selected to be fattened and slaughtered.100 meat samples of GBF1 feedlot steers and Yunling feedlot steers were collected and sealed in clean fresh frozen bag.With the meat samples from Yunling feedlot steers as the control, the shear force, lose water ratio, water holding ratio and cooking loss of meat samples from GBF1 were determined.The results showed that the shear force of shoulder crest from GBF1 cattle were significantly higher than that from Yunling cattle (P< 0.05), and there were no significant differences in the others meat samples (P> 0.05).The average shear force, average lose water ratio, average cooking loss of 10 different cuts from GBF1 cattle were 3.50 kg, 24.15%, 27.56%, respectively and lower than that of Yunling cattle (P> 0.05).The average water holding ratio was 64.60% and higher than that of Yunling cattle (P> 0.05).In conclusion, the meat quality of GBF1 cattle was good, similar to that of Yunling cattle.

Key words: Gayal; Brahman; interspecies crossbreeding; GBF1 cattle; Yunling cattle; meat quality
