Casing performance of guinea pigs fed with tropical grasses Axonopus scoparius, Pennisetum SP, Pennisetum purpureum and Tripsacum laxum in Morona Santiago

Abstract

The performance of male guinea pigs fed with four tropical grasses in Morona Santiago, was developed in the ESPOCH Morona Sede, for which four pastures were used: Axonopus scoparius (Gramalote - T1), Pennisetum sp (Maralfalfa) (T2), Pennisetum purpureum (Elephant grass) (T3) and Tripsacum laxum (Guatemala grass) (T4) with ten repetitions, giving a total of 40 male guinea pigs, the same ones that consumed the indicated pastures from weaning to slaughter (150 days old) and were distributed completely at random and their results were analyzed through variance and Tukey's test (p <0.05). determining that the use of Axonopus scoparius allowed a weaning weight of 247.84 g, the slaughter weight of 1107.52, 599.63 g of carcass weight and its performance without fasting of 54%, the weight and yield of the viscera, hair and blood was 507.89 g and 45.70%, the weight and yield only of viscera was 375.83 g and 33.80%, the weight and yield of the hair was 78.14 g and 7.06% and the weight and yield of the blood was 53.92 g and 4.84 % respectively, indicating that this pasture was more efficient.
