The Analysis of Hybrid Effects of Different Hybridization Combination Using Semental Cattle and Angus Cattle
【Objective】To evaluate the hybridization effects of the different hybridization combination using Semental cattle and Angus cattle.【Method】Three hybridization combination(I,II and III),namely, male Simental cattle hybridizing with female local-high-hybridized cattle with the Simental cattle's blood(group I),female Simental cattle hybridizing with male local-high-hybridized cattle with the Angus cattle's blood(group II),male Angus cattle hybridizing with female local-high-hybridized cattle with Simental cattle's blood(goup III)were designed and were used to evaluate the hybridization effects.【Results】In the same management,the birth weight and average body weight of the 6month old,12month old,18month old and 24month from the group II cattle were significantly weigher than other groups(P0.05),respectively.These indexes from the group I cattle was obviously better than those from the group III.There was no significant difference in the daily gain of the 6month old,18month old between the group I and group III,but the the daily gain of the 12month old and 24month old from the group I were obviously better than those of Group III.Moreover,the daily gain of the 6month old,12month old,18month old and 24 month from group II were better than those from group I and III.【Conclusion】Simental cattle and Angus cattle demonstrated better hybridizing effect,and Simental cattle showed better the hybridization effect than the Angus when they hybridized with the local cattle.
