Description
The influence of feeding the sows by diets supplemented with natural immunomodulators on fertility parameters, were investigated on one large pig farm in AP Vojvodina (Serbia). The diets of pregnant, lactating and weaned sows (in the period weaning-to-fertile estrus) were suplemented with preparations containing premium colostrum, yets and herbal extracts, to stimulate immune system. Farrowing rate ( AI within ≤ 7 days after weaning), in treated sows was significantly (p<0.01) greater (87.6%, 204/233) then in
kontrol (untreated) sows (83.7%, 160/205). Average total born and liveborn piglets per litter, in treated (10.4 and 10,3 resp.) and in control sows (10.2 and 10.0 resp.) was not significant different (p>0.05), but the average stillborn piglets per litter was significantly (p<0.05) lower in treated (0.14), compared with control sows (0.21). Our data suggest that the application of natural immunodulators
can increase the sows fertility in the intensive pig production.
