Abstract

Pig Respiratory and Reproductive Syndrome (PRRS) is an en- demic disease in pigs that tends to become chronic. Efforts are focused on prevention and control to minimize damage, as no treatment exists. The effect of adding docosahexaenoic acid (DHA) and turmeric oleoresin and capsicum (plant extracts, PE) in the feeding of breeding sows affected with PRRS on their productive performance, health and progeny was evaluated. Forty-eight first-parturition sows were randomly distributed into four treatments (Tr1, control; Tr2, DHA; Tr3, PE; Tr4, DHA+PE). The second parturition assay followed the same design. Tr3 and Tr4 got more piglet weight at birth in both parturitions (P < 0.05) than the others. In both deliveries, the addition of DHA and PE resulted in fewer mummies (P < 0.05) and lower cost than the other treatments. Tr3 had a higher number of live piglets in both parturitions, while Tr4 only got that in the second parturition (P < 0.05). More piglets were weaned in Tr2 and Tr3 (P > 0.05) in the first parturition; but Tr2 outperformed the others in the second parturition (P > 0.05). By ELISA, all pigs developed antibodies against PRRS. The groups receiving DHA and/or PE had higher serum IgG concentrations than control (P < 0.05). It is concluded that the addition of DHA and PE improves the productive response and induced higher concentrations of IgG in both parturitions, in addition to reducing the production cost of sows.
