| 摘 要： | 利用 6月龄夏西本、皮西本、利西本、西杂二代各 1 0头进行 36 5天育肥 ,研究不同杂交组合对肉牛生长发育及饲料消耗的影响。结果表明 ,1 8月龄各组试验牛体重分别达到 ( 5 2 9 5 0± 2 3 38)kg、( 5 82 2 5±2 9 2 5 )kg、( 5 35 6 3± 2 7 88)kg、( 5 0 4 0 0± 2 4 2 5 )kg,平均日增重以皮西本、利西本和夏西本较高 ,分别为 0 96kg、0 90kg和 0 83kg,皮西本、利西本与西杂二代 ( 0 77kg)比较 ,差异显著 (P <0 0 5 ) ;饲料报酬以皮西本较好 ,每公斤增重消耗精、粗饲料分别为 4 0 3kg和 5 98kg。 3个三元杂交组合体尺均大于对照组 (西杂二代 ) ,但各项体尺指数均差异不显著 (P >0 0 5 )。

Comparison of growth and feed efficiency of crossbred beef cattles from different combinations |
| |
| Abstract: | The body weight gain, body size parameters and feed efficiency of the three-way cross beef cattles were measured and analyzed from 6-month-old to 18-month-old, and the crossbred beef cattles were the progenies of Charolais, Simmental and local yellow cattle(CSB), Piemontese, Simmental and local yellow cattle(PSB), Limousin, Simmental and local yellow cattle(LSB),and crossbred F 2 of Simmental and local yellow cattle(SSB). The results showed that their body weights at 18 months old were (529.50±23.38)kg, (582.25±29.25)kg, (535.63±27.88)kg and (504.00±24.25)kg respectively. The daily body weight gains of PSB, LSB and CSB were 0.96kg, 0.90kg and 0.83kg respectively. And the feed efficiency of PSB was relatively higher. All these beef cattles had better beef type based on their indexes of body size, but no significant difference (P>0.05). |
