Abstract
Esta investigación se ha realizado para determinar la densidad de gorrinos cruce Pietrain-Duroc, en velocidad de crecimiento y conversión alimenticia en etapa de crecimiento. Se evaluaron 76 cerdos machos y hembras de 71 días de edad, distribuidos en un diseño de bloques completamente al azar con dos repeticiones. Se usaron tres tratamientos con diferentes áreas efectivas: T1 con 1,00 m2 por animal, T2 con 0,94 m2 por animal y T3 con 0,87 m2 por animal, durante un periodo de 29 días. Se determinó velocidad de crecimiento, conversión alimenticia, eficiencia económica, incremento de peso y consumo de alimento. El tratamiento T1 obtuvo la mayor velocidad de crecimiento (870 ± 0.09 g macho y 850 ± 0.11 g hembra), la mejor conversión alimenticia (1.92 ± 0.018 macho y 1.94 ± 0.024 hembra), eficiencia económica (1.64 macho y 49.05 ± 1.58 hembra), el mayor incremento de peso (51.24 ± 0.476 Kg macho y 49.05 ± 0.615 Kg hembra) y consumo de alimento (49.33 ± 0.221 Kg macho y 49.05 ± 0.615 Kg hembra) (p < 0.05). En todos parámetros productivos se estableció una diferencia estadística entre sexos (p < 0.05). En conclusión, el tratamiento T1 con una densidad de 1,00 m2 de área efectiva por cerdo, logró obtener la mejor velocidad de crecimiento y conversión alimenticia; por lo que, la densidad, es un factor importante en la crianza de porcinos.
ABSTRACT The aim of this research was determining the density of Pietrain-Duroc crossbreed pigs, in growth speed and feed conversion in growth stage. 76 pigs of 71-day-old between male and female were evaluated, distributed in a completely randomized block design with two repetitions. Three treatments were used with different effective areas: T1 with 1.00 m2 per animal, T2 with 0.94 m2 per animal and T3 with 0.87 m2 per animal, during a period of 29 days. Growth speed, feed conversion, economic profitability and other productive parameters were determined. Treatment T1 obtained the greatest weight gain (51.24 ± 0.476 Kg Male and 49.05 ± 0.615 Kg Female), growth speed (870 ± 0.09 g Male and 850 ± 0.11 g Female), feed intake (49.33 ± 0.221 Kg Male and 49.05 ± 0.615 Kg Female), the best feed conversion (1.92 ± 0.018 Male and 1.94 ± 0.024 Female) and economic efficiency (1.64 Male and 49.05 ± 1.58 Female) (p <0.05). In addition, in all productive parameters a statistical difference was established between the sexes (p<0.05). In conclusion, the T1 treatment with a density of 1.00 m2 of effective area per pig, achieved the best growth rate and feed conversion; so, density, is an important factor in pig farming.
