Each week increase in the age at weaning increased ADG
(Po0.001) and ADFI(Po0.001)from weaning to 2weeks
postweaning, from 2 weeks postweaning to 10 weeks of
age and from weaning to 10 weeks of age. Weaning age did
not affect FCR in the period from weaning to 2 weeks
postweaning (P40.05) or from 2 weeks postweaning to 10
weeks of age(P40.05); however,during the period from
weaning to 10 weeks of age,FCR of pigs weaned at 5
weeks of age was improved compared with pigs weaned at
3 and 4 weeks of age(Po0.05).
Multiple regression analysis yielded the following prediction equations:
