Abstract

The study was conducted to evaluate the fattening performance of Arsi, Borana, Harar and HF-Crossbred bulls finished under similar feeding condition at the beef farm in Haramaya University. A total of 24 bulls with age categories of 2-3 and 4-5 years were used in the complete block design for the experiment. Total mixed ration was provided at 3% of their BW during experimental periods. The average daily weight gain of the four breeds range from 0.49 to 0.71 kg. Feed conversion efficiency also ranges from 0.11 – 0.15. Simple linear regression models were used to explore the relationship between live body weight change and change in BCS as well as seven linear body measurements for all age groups. An average change for a unite of body condition score was equivalent to 20.3, 20.61, 22.42 and 27.78kg for Borana, Arsi, Harar and HF-crossbred bulls respectively. BCS was significantly (P<0.01) influenced by breeds. There was a significant (P<0.05) breed by age interaction effect on the initial body condition score of the four breeds. There was a significant and positive strong association between change in BW and BCS. There was a significant and strong correlation between change in BW and change in Total topline, neck length, heart girth, flank circumference and rump length having correlation coefficient ranges (r = 0.57 to 0.97). Higher (P<0.01) net profit of 7,380.47 ETB per head was recorded by Borana bulls followed by Harar bulls, Arsi and HF Crossbred with net profit of 5,406.86, 5193.29 and 3,384.98 ETB per head respectively.
阿西、博拉纳、哈拉尔和hf杂交公牛在相同饲喂条件下的生长性能
本研究在原谷大学肉牛场对Arsi、Borana、Harar和hf杂交公牛在相似饲养条件下的育肥性进行了评价。试验选用24头公牛,年龄分别为2 ~ 3岁和4 ~ 5岁。试验期间,按猪体重的3%饲喂混合日粮。4个品种的平均日增重为0.49 ~ 0.71 kg。饲料转换效率也在0.11 - 0.15之间。采用简单线性回归模型探讨各年龄组活体重变化与BCS变化及7项线性身体测量之间的关系。博拉纳公牛、阿尔西公牛、哈拉尔公牛和hf杂交公牛的体况评分单位平均变化分别为20.3、20.61、22.42和27.78kg。BCS受品种影响极显著(P<0.01)。年龄互作对4个品种初始体况评分的影响显著(P<0.05)。体重变化与BCS之间存在显著的正相关关系。体重变化与总背线、颈长、胸围、腹围、臀长变化呈显著强相关(r = 0.57 ~ 0.97)。博拉纳公牛的净利润最高(P<0.01),为7380.47 ETB /头,其次是哈拉公牛、阿尔西和HF杂交公牛,分别为5406.86、5193.29和3384.98 ETB /头。
