Abstract
The possibility of improving sows reproductive indexes by supple-mentation of feed mixtures with Probiodor containig diatomite and bipolarity microelements was investigated in the experiment carried out on 58 sowe (PL x PLW) fed ecologically.
Sows in control group (21 animals) were fed restricted standard feed mixture. Sows in the group II in addition to experimental feed mixture received ad libitum silage made of whole maize plants, and group III - grass silage. The Probiodor supplement was used for 9 sows in control group, 8 sows in group II and 7 in group III. All piglets were weaned at 42nd day of age and the experiment lasted till 84th day of age.
Results of the experiment show that sows receiving Probiodor charsad higher body weight gains between mating and farrowing (by 9 - 13 kg) and from mating to weaning (by 1.2 - 10.9 kg). However, bigger body weight loss during lactation was observed in experimental sows when compared with controls. Probiodor supplementation increased the number of born piglets in litter by 0.35 in the control group 0.73 in group II and 1.12 in group III. A little lower mortality was noticed in piglets of sows receiving Probiodor. Their body weight was higher, especially between 42nd - 63rd day of age by 29 g in group II and 113 g in group III.
