Resumen
El presente trabajo de investigación se realizó en la en la granja de la Facultad de Veterinaria
Facultad de Veterinaria y Zootecnia de la Universidad Nacional San Luis Gonzaga de Ica,
ubicado en el distrito de Alto Larán provincia de Chincha, departamento de ICA, con el
objetivo de evaluar tres niveles de gallinaza al 0, 5 y 10 % en dietas para cuyes en crecimiento
con exclusión de forraje, con los que se formaron tres tratamientos en la etapa de
crecimiento.
El método que se él se emplearon 60 cuyes todos machos, los animales seleccionados fueron
de líneas mejoradas obtenidos de cruces con raza Perú, de 14 ± 3 días de edad.
Los resultados no indican diferencias estadísticas significativas para el peso inicial entre
tratamientos, pero si en el peso final, obteniéndose: T1 826 g (0% G), T2 838 g (5% G), T3
875 g (10% G). En cuanto a la conversión alimenticia, se obtuvieron mejores resultados en
los tratamientos cuyos niveles de gallinaza fueron al 5 y 10% siendo estos de 3.7 y 3.6
respectivamente. Asimismo, se encontró diferencias estadísticas significativas para el
consumo de materia seca total (solo alimento balanceado) registrándose alrededor de 2025
a 2171 g.
Los rendimientos de carcasa alcanzados fueron de 69.25% y 69.30% para los tratamientos
cuyos niveles de HG fueron los que obtuvieron mejor respuesta en ganancia de peso T2 y
T3 (5 y 10% HG); en cuanto a la grasa de cobertura que presenta la carcasa este disminuyó
en los tratamientos cuyo nivel de HG fue mayor.
The present research work was carried out on the farm of the Faculty of Veterinary Medicine, Faculty of Veterinary Medicine and Zootechnics of the National University San Luis Gonzaga de Ica, located in the district of Alto Larán, province of Chincha, department of ICA, with the objective to evaluate three levels of chicken manure at 0, 5 and 10% in diets for growing guinea pigs with exclusion of forage, with which three treatments were formed in the growth stage. The method used was 60 guinea pigs, all males, the selected animals were from improved lines obtained from crosses with the Peru breed, 14 ± 3 days old. The results do not indicate significant statistical differences for the initial weight between treatments, but in the final weight, obtaining: T1 826 g (0% G), T2 838 g (5% G), T3 875 g (10% G). Regarding feed conversion, better results were obtained in the treatments whose chicken manure levels were 5 and 10%, these being 3.7 and 3.6 respectively. Likewise, significant statistical differences were found for the consumption of total dry matter (balanced food only), registering around 2025 to 2171 g. The carcass yields achieved were 69.25% and 69.30% for the treatments whose HG levels were those that obtained the best response in weight gain T2 and T3 (5 and 10% HG); Regarding the covering fat of the carcass, it was reduced in the treatments whose HG level was higher.
