Reproduction in the gilt 6. the effect of various degrees of mature boar contact during rearing on puberty attainment



Reproduction in the gilt 6. the effect of various degrees of mature boar contact during rearing on puberty attainment



Animal Production 43(2): 341-350



Forty-eight Landrace .times. (Landrace .times. Large White) gilts were randomly allocated at 70 days of age to each of three rearing treatments: (1) fence-line contact with a mature boar, (2) olfactory/aural contact with a mature boar, (3) no boar contact. At 160 days of age, all gilts were relocated adjacent to a novel mature boar and exposed to full contact with a mature boar for 30 min each day. At the first, second and third estrus, 16 gilts from each treatment group were mated twice and the reproductive tracts were examined at slaughter 21 days later, to determine ovulation rate and embryo survival. The rearing treatments had no significant effects on the attainment of puberty. Neither rearing treatment nor estrus of mating had any significant effect on behavior, sexual receptivity at first service, conception rate, ovulation rate, the number of embryos and embryo survival at 21 days of pregnancy.
