Efecto de la inclusión de papa (solanum tuberosum) en el concentrado comercial sobre el desempeño productivo de cerdos castrados y no castrados en fase de crecimiento.

Abstract

The increase in the world population and the high cost of commercial feed leads to the search for cheaper alternative sources of energy for feeding pigs, the present investigation aimed to evaluate the effect of the inclusion of cooked potato in commercial concentrate on productive parameters: feed conversion, weight gain, feed efficiency, productivity index comparing castrated pigs with non-castrated pigs, as well as the economic benefits. In this research, 12 landrace breed pigs were used per pietrain in the growth phase with an age of 75 days and an initial body weight of 20 kg. The animals were distributed in a completely randomized design in a 2 x 2 factorial scheme, with 4 treatments and 3 repetitions. The evaluated treatments were: non-casted pigs receiving commercial concentrate including 40% cooked potato; castrated pigs receiving commercial concentrate including 40% cooked potato; non-castrated pigs receiving 100% with commercial concentrate and; castrated pigs receiving 100% with commercial concentrate. Statistical procedures were analyzed by PROC MIXED of the SAS (Version 9.4), weight gain, final body weight, consumption, conversion and feed efficiency were subjected to ANOVA, adopting the initial body weight as a covariate. Statistical significance will be considered when P≤0.05, and trend when 0.05≤P≤0.10
