Comparative examination of performance test results of gilts castrated and entire males of different pig breeds

Comparative examination of performance test results of gilts castrated and entire males of different pig breeds

Allattenyesztes es Takarmanyozas 31(4): 333-344

The data of 123 Hungarian Large White (HLW) (41 gilts, 41 castrated males and 41 entire males), 141 (3 .times. 47) Duroc (D) and 36 (3 .times. 12) Swedish Landrace (SL) were examined. Castrated HLW, D and SL males consumed 8.0, 3.0 and 8.5% more compound feed, respectively, than boars of the same breed. No significant difference was found between daily body gain of castrated and entire males of either breed tested. HLW and D entire males produced significantly better FCR than castrated males. HLW, D and SL boars produced less fat than castrated males, the difference was statistically significant at levels of P < 0.1%, P < 1.0% and P < 5.0%, respectively. HLW and D males produced more valuable meat than castrated males of the same breed, the difference was statistically significant at P < 0.1% and P < 5.0%, respectively. No difference in lean production of SL pigs was found. The higher the genetically determined capacity for meat production, the smaller difference can be expected in lean meat and fat production of castrated and entire males. The substitution of castrated males by boars in the performance test carried out by ad lib feeding is not suggested. Decision needs further examinations.
