长白山野猪不同杂交组合生长性能比较研究

本试验选择体重30Kg左右的野杂猪，野×丹（18头），野×长×丹（18头），野×丹×丹（18头），野×野×丹×丹（18头）分4组进行饲养试验。结果表明：野×长×丹组和野×丹×丹组的日增重最高，极显著（P〈0．01）高于另外两组；野×野×丹×丹组次之，极显著（P〈0．01）高于野×丹组；野×丹组最低，仅为521g；野×长×丹组与野×丹×丹组之间差异不显著（P〉0．05）。说明长白山野猪不同杂交组合的生长性能与野猪的血缘比例呈负相关，随着野猪血缘比例的降低，生长性能明显提高。

Comparative Study on the Growth Performance of Different Hybrid Combinations of Clmngbai Mountain Boar

In this experiment, hybridism boar, about 30 Kg weight were divided into 4 groups of breed experiment： The first group of boar x Dandong black swine（18） ;The second group of boar × Changbai Mountain Boar swine × Changhai Mountain Boar black swine（18） ;The third group of boar× Dandong black swine × Dandong black swine （ 18）and the fourth group of boar x boar × Dandong black swine × Dandong black swine（18）. Results showed that： difference of compared the second and the third groups with other groups were very predominance（P 〈 0.01 ）, add weight per day was topmost; Difference of compared the fourth group with the first group was very predominance（P 〈 0.01）, The first group was lowest, add weight per day was 521g; difference of compared the second group with the third group was not predominance （ P 〉 0.05）. Demonstration that hybridized combination of Changbai Mountain Boar relation growth efficiency with boar blood relationship proportional was negative correlation, growth efficiency was raised obviously, along with boar blood relationship proportional cut down.
