Brahman cattle are tolerant to parasite challenges and heat stress. Yunling cattle are three-way hybrids that are half Brahman cattle, a fourth Murray Grey cattle and a fourth Yunnan Yellow cattle, with good beef performance. The hematological and biochemical parameters can reflect the physiology and metabolic conditions of cattle, and there are valuable indicators of production performance and adaptability that can be found by studying the cattle. To assess the health status and differences, we compared 55 hematological and biochemical parameters of 28 Brahman cattle and 65 Yunling cattle using an automatic biochemical analyzer. Our results showed that 27 hematological and biochemical indices of Brahman cattle were lower than those of Yunling cattle, whereas the other parameters were higher. There are 20 indices with significant differences that were detected between Brahman and Yunling cattle (with p ≤ 0.01 or 0.01 ≤ p ≤ 0.05, respectively), and no significant differences were found for other indices (p > 0.05). Based on these results, Yunling cattle may have a better physical condition than Brahman cattle, may be better at adapting to local environments, and can maintain a good production and reproduction performance. As a new breed that is half Brahman, the abilities of Yunling cattle, including adaptability, stress resistance and tolerance to crude feed, were better than Brahman cattle under the same management conditions.
婆罗门牛对寄生虫侵袭和热应激具有耐受性。云岭牛是三元杂交牛,含有一半婆罗门牛血统、四分之一墨累灰牛血统和四分之一云南黄牛血统,具有良好的产肉性能。血液学和生化参数能够反映牛的生理和代谢状况,通过对牛的研究可以找到生产性能和适应性方面的有价值指标。为了评估健康状况和差异,我们使用自动生化分析仪比较了28头婆罗门牛和65头云岭牛的55项血液学和生化参数。我们的结果表明,婆罗门牛的27项血液学和生化指标低于云岭牛,而其他参数则更高。在婆罗门牛和云岭牛之间检测到20项有显著差异的指标(分别为p≤0.01或0.01≤p≤0.05),其他指标未发现显著差异(p>0.05)。基于这些结果,云岭牛的身体状况可能比婆罗门牛更好,可能更能适应当地环境,并且能够保持良好的生产和繁殖性能。作为一种含有一半婆罗门血统的新品种,在相同管理条件下,云岭牛的适应能力、抗应激能力和对粗饲料的耐受性均优于婆罗门牛。
