Abstract:
At the first fertile services, the dynamics of boars
weight increase was tributary to body weight, which must be over 100 kg.
Different weights resulted in differences of the values of body indices in
female mates. Prolificacy, weight of pigs group at birth, weight of pigs
group at 21 days and weight of pigs group at weaning represented the
parameters influenced by differences in boar weight. Suckling capacity,
weight of pigs at weaning and number of pigs at weaning were the
reproductive parameters influenced by age differences in boars. The
optimum age for reproduction in boars must be of 224-252 days. The
requirements concerning age and body weight must be satisfied at first
fertile periods.
