Evaluación de un alimento peletizado a base de forraje para conejos en fase de levante y ceba en la Granja Experimental Villa Marina

The objective of this study is to evaluate a pelleted feed based on fodder for rabbits in the uprising and fattening phase in the Villa Marina Experimental Farm on the productive parameters of weight gain, feed conversion, feed efficiency, carcass yield and costs per concept of supplementation. The trichanthera gigantea, Tithonia diversifolia, Paspalum dilatatum and Erythrina edulis forages were included in the production of the pellets. The inclusion percentages were obtained through a Composite Pearson Square and subsequently a sample of the pellet made was sent to the Animal Nutrition laboratory of the University of Tolima to determine its nutritional composition. A randomized complete block design with two treatments was used, one with 100% of the forage-based pellet and the second with 50% of this pellet and 50% of commercial feed and a witness, five animals for each of them . The investigation period was 60 days and the data were taken seven days. Finally, descriptive statistics tests, analysis of variance were applied, using the Tukey test with a significance of 5% and Pearson's correlation to estimate the effect of race or crossing and sex on the productive parameters. The parameters evaluated did not show significant statistical differences (P> 0.05). The channel performance was varied, with the control predominant with 52.50%. The value of kg of rabbit meat for food was estimated at $ 5,083 with the supply of forage-based pellets at 100%, being cheaper than treatment 1 and the control at $ 1,533 and $ 3,327 respectively. The results show that the forage-based pellets do not affect the productive yields in rabbits in the fattening phase obtained with the commercial balanced feed. El objetivo del presente estudio es evaluar un alimento peletizado a base de forraje para conejos en fase de levante y ceba en la Granja Experimental Villa Marina sobre los parámetros productivos de ganancia de peso, conversión alimenticia, eficiencia alimenticia, rendimiento en canal y costos por concepto de suplementación. En la elaboración de los pellets se incluyeron los forrajes Trichanthera gigantea, Tithonia diversifolia, Paspalum dilatatum y Erythrina edulis. Los porcentajes de inclusión se obtuvieron a través de un Cuadrado de Pearson Compuesto y posteriormente se remitió una muestra del pellet elaborado al laboratorio de Nutrición Animal de la Universidad del Tolima para determinar su composición nutricional. Se empleó un diseño de bloques completos aleatorizado
