title: [The effect of vitamin administration to sows during weaning on the weaning-estrus interval and on the number of live piglets in the next litter].
abstract: The effect of injection of additional vitamins in sows during weaning on the weaning-oestrus interval and on the number of piglets born alive in the next litter was studied in 735 sows. On five commercial farms, a total of 735 sows were divided into 3 groups. The first group was injected with 10 ml of a preparation of AD3E. The second group was injected with 10 ml multivitamin. The third group was not treated. It is concluded that injection of additional vitamins did not have any effect on the weaning-oestrus interval and on the number of piglets born alive in the next litter.
