QUEZADA-FRAIDE, Elizabeth Araceli et al. Productive performance and costs of swine farms with different PRRS virus vaccination protocols. Rev. mex. de cienc. pecuarias [online]. 2021, vol.12, n.1, pp.205-216. Epub 20-Set-2021. ISSN 2448-6698. https://doi.org/10.22319/rmcp.v12i1.5377.
In order to evaluate the productive performance and production costs per weaned piglet and finished pig in swine farms with different PRRS virus vaccination protocols under field conditions, the indicators total piglets born alive, stillborn piglets, weaned piglets, birth and weaning weights, fattening days and final weight, as well as the costs per weaned piglet and finished pig of two farms under a semi-technification regime were analyzed: a) Protocol 1 (P1), a farm with vaccination of breeding sows and piglets; and b) Protocol 2 (P2), vaccination of breeding sows only. The productivity indicators up to weaning were evaluated with a Time-Repeated Measures Design, and the fattening indicators were evaluated with an analysis of variance with comparison of means. The costs were determined using the general cost formula. It was possible to observe differences in total number of piglets born and of mummies (P<0.05) in favor of P2, weaned piglets, as well as in birth and weaning weights in favor of P1, but no differences in the rest of the variables. Pigs finished in P1 resulted in 12 more days of fattening and a final weight of 3.13 kg more than P2. The costs per weaned piglet were $389.55 and $424.25 Mexican pesos, and the average cost per day of fattening were $10.01 and $11.43, respectively.
