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.
在735头母猪中研究了断奶期间给母猪额外注射维生素对断奶至发情间隔以及下一窝产活仔猪数目的影响。在五个商业农场，共735头母猪被分为3组。第一组注射10毫升AD3E制剂。第二组注射10毫升多种维生素。第三组不进行处理。得出的结论是，额外注射维生素对断奶至发情间隔以及下一窝产活仔猪数目没有任何影响。
