Reproductive Functions of Sows When Using a Probiotic in the Diet

This paper presents data on the use of the Bifidum Bag probiotic in the diets of pregnant sows and piglets of the preweaning period. The highest average daily gain in live weight during the pregnancy period and loss of live weight over the lactation period are observed in sows of the II experimental group, which received the Bifidum Bag probiotic feed additive. Consequently, the Bifidum Bag feed additive in the diets of pregnant sows, against the background of a balanced feeding, has a positive effect on the average daily gain in live weight of pregnant sows. A positive effect can also be traced in the survivability of piglets. The survivability of piglets of the II experimental group was higher by 5.7%, the average daily gain of piglets of the II experimental group at the time of weaning exceeded the piglets of the I control group by 300 g. As a result, the studied Bifidum Bag probiotic feed additive has a positive effect on the reproductive functions of sows, the growth and development of piglets of the preweaning period.
