Abstract
El presente estudio se desarrolló en la granja modelo del Pago de Azángaro Grande, Porvenir, Huanta, Ayacucho. Se trabajó con 40 cuyes machos de la raza Perú, de cuatro semanas de edad con un peso promedio de 0,435 Kg, utilizando forraje verde hidropónico (FVH) de cebada (Hordeum vulgare) como base alimenticia de cuatro sistemas de alimentación para evaluar durante 60 días su efecto sobre el comportamiento productivo: consumo de forraje (CF), conversión alimenticia (CA), peso vivo (PV), peso a la canal (PC), rendimiento a la canal (RC) y ganancia de peso (GP), aplicando cuatro tratamientos en un diseño completamente al azar. Los datos se procesaron con el análisis de varianza (ANVA), aplicando la prueba de rangos múltiples de Tukey P≤0,05) para determinar diferencias entre medias de tratamiento. El mayor CF (P<0,01) fue del FVH + concentrado (42,49 g animal-1 día-1), seguidos de los valores 41,07, 40,05 y 36,46 para FVH + follaje de camote, FVH + residuos de molinería y FVH + alfalfa, respectivamente. La dotación de FVH + alfalfa permitió aumentar (P<0,01) el PV (915,70 g); la GP (9,06 g animal-1 día-1) y CA más eficiente (4,24). Se concluye que al suministrar FVH + alfalfa se consigue mayor PV, PC y RC, así como también mejor CA en el engorde de Cavia cobayo.
The present study was developed in the model farm of Pago de Azángaro Grande, Porvenir, Huanta, Ayacucho. We worked with 40 male guinea pigs of the Peru breed, four weeks old with an average weight of 0.435 kg, using hydroponic green fodder (HGF) of barley (Hordeum vulgare) as feed base of four feeding systems to evaluate for 60 days its effect on productive behaviour: forage intake (FI), live weight (LW), feed conversion (FC), carcass weight (CW), carcass yield (CY) and weight gain (WG), applying four treatments in a completely randomized design. Data were processed with analysis of variance (ANOVA), applying Tukey's multiple range test (P≤0.05) to determine differences between treatment means. The highest FI (P<0.01) was for FVH + concentrate (42.49 g animal-1 day-1), followed by 41.07, 40.05 and 36.46 for FVH + sweet potato foliage, FVH + milling residues and FVH + alfalfa, respectively. The provision of FVH + alfalfa allowed an increase (P<0.01) in LW (915.70 g); WG (9.06 g /animal / day) and more efficient FC (4.24). It is concluded that by supplying FVH + alfalfa, higher LW, CW and CY are achieved, as well as better FC in guinea pig fattening.
