Variation, heritability and relationships of reproductive traits in Large White pigs



Variation, heritability and relationships of reproductive traits in Large White pigs



Nauchnye Trudy Leningradskogo Sel' skokhozyaistvennogo Instituta 355: 61-66



Data on 56 dam-daughter pairs of sows that had produced more than or equal to 2 litters were analysed. For dams and daughters resp., litter size averaged 10.76 and 10.54 (CVs = 6.93 and 10.82%), litter weight at 21 days of age 43.02 and 41.95 kg (5.69 and 9.48%), and litter weight at weaning (2 mth of age) 131.60 and 121.62 kg (16.24 and 17.31%). The h2s of the 3 traits were 0.29, 0.17 and 0.80.
