摘要:

为了解长期高营养饲喂对婆罗门育肥牛健康的影响,为生产健康、优质牛肉提供理论指导,试验采用自动生化分析仪和试剂盒,以12头相同饲养环境和不同营养水平下饲养的去势婆罗门牛为研究对象,在为期24个月育肥后,分别检测其血液理化指标,并与传统放牧组婆罗门牛的血液理化指标进行了比较。结果表明:测定53个指标中有18个指标随着营养水平的升高有逐渐增加的趋势,即WBC、RBC、HB、HCT、MCHC、PLT、PCT、MPV、P-LCR、TG、TBA、GLU、Cr、HCY、CK、ALP、K+、P5+等,而TP、AST、ALT、GGT和HCO3- 5个指标等指标随营养水平的升高而降低;其余指标在组间无显著差异。总之,通过加强营养和饲养管理后,育肥牛的血液指标得到改善,提高了动物机体各种脏器功能,更有利于脂肪和肌肉的沉积。去势婆罗门公牛经过长时间(2.5年)的高营养、中营养饲养条件下进行强度直线育肥生产出的优质、高档牛是健康的。

Abstract:

The aim is to clarify the effect of long-term high nutritional level on the health of fattening Brahman cattle, and provide theoretical support for the production of healthy and high-quality beef. Automatic biochemical analyzer and kit were used in this study. 12 castrated Brahman bulls under different nutritional levels with same pen-feeding management were used as materials. After 24-month fattening, the blood physicochemical indicators were tested and compared with the traditional grazing group. The results showed that 18 of 53 biochemical indicators increased with the increase of diet nutritional level, including WBC, RBC, HB, HCT, MCHC, PLT, PCT, MPV, P-LCR, TG, TBA, GLU, Cr, HCY, CK, ALP, K +, P 5+, while 5 indicators (TP, AST, ALT, GGT, and HCO3 -) decreased. Other indicators had no significant difference between the groups. In conclusion, through strengthening nutrition and feeding management, the blood indicators are improved in Brahman cattle and the functions of various organs are enhanced to favor the fat deposition and muscle growth. The castrated Brahman bulls could be high-quality and high-grade cattle by direct intensive fattening under the condition of medium and high nutritional levels for a period of 30-month.

Key words: Brahman, high nutritional, biochemical indicators, pen-feeding, grazing
