Abstract

Objectives: To evaluate the effects of the season of the year and farrowing number on the reproductive and productive characteristics of the Camborough 29 swine genetic line. Methodology: Records of 85 sows from a commercial farm in Huaral (Lima, Peru) were evaluated, from a period of three years (2011-2013), to determinate the effect of the season of the year (SY, winter and summer) and the number of farrowing (NF, 1 to 5) on the reproductive characteristics: fertility rate (FR) and parturition rate (PR) and productive: weaning-conception interval (WCI), Live born piglets (LBP), litter size at weaning (LSW), average weaning weight (AWW) and percentage of stillborn piglets (% SP). The data were analyzed using the chi square test and the analysis of variance. Results: SY did not influence (P>0.05) on FR (97 vs 99) and PR (96 vs 97); but there was a influence (P<0.05) on the WCI (14.8 vs 9.4 days). NF influenced (P<0.05) in LBP (12.91; 12.90; 13.87; 15.38 and 14.53), % SP (3.09, 2.87, 2.39, 6.50 and 5.72) and in the AWW (6.04; 6.53; 6.64; 6.49 and 6.85 kg) but it did not statistically influence (P>0.05) in the LSW (11.46; 11.36; 11.42; 10.73 and 12.35). Conclusions: The season of the year only influenced in the WCI while the number farrowing had effect on the LBP, %SP and AWW.
