 en Performance of Grazing Growing Cattle Supplemented With Cocoite Foliage ( Gliricidia Sepium check for this species in other resources ), Multinutritional Blocks, and Commercial Diet in the Mexican Humid Tropic
Montes, Francisco Reyes; Nava, Guillermo & González, Roberto

Abstract

This study was aimed to evaluate the performance of growing cattle supplemented with cocoite foliage ( Gliricidia sepium check for this species in other resources ), multinutritional blocks formulated with bran cocoite, and commercial diet during the dry season (april to may) in a humid tropic condition. The experiment was carried out in an area at Teapa municipality, Tabasco, Mexico. Twenty growing cattle breed of Cebu x Holstein x Simmental with average weight of 230.5 kg were used in rotational grazing of star grass ( Cynodon nlemfuensis check for this species in other resources ). A random design corrected by weight covariance was used. Four treatments (T1: control, only grazing, T2: grazing + commercial diet, T3: grazing + multinutritional blocks, and T4: grazing + cocoite foliage) and five repetitions were used. The experiment was conduced during 10 adaptation days and 56 experimental days. In this period the consumption was measurement by the difference between offered and refused. The daily weight gains were 0.664, 1.071, 0.767, and 0.617 kg/anim to T1, T2, T3, and T4, respectively. The costs of supplementation per animal were 1.4, 0.05, and 0.49 USD for T2, T3, and T4, respectively. The results obtained showed that the multinutritional blocks could be incorporated into the grazing growing cattle fattening system.

 es Respuesta de Toretes en Pastoreo a la Suplementación Con Follaje de Cocoite ( Gliricidia Sepium check for this species in other resources ), Bloques Multinutiricionales y Alimento Comercial en el Trópico Húmedo de México
Montes, Francisco Reyes; Nava, Guillermo & González, Roberto

Resumen

El objetivo del presente trabajo fue evaluar la respuesta animal a la suplementación de follaje de cocoite ( Gliricidia sepium check for this species in other resources ), bloques multinutricionales a base de harina de cocoite y alimento comercial, durante la temporada seca (abril a mayo) en condiciones de trópico húmedo. El experimento se realizó en un área ubicada en el municipio de Teapa, Tabasco, México. Se utilizaron 20 novillos con diferentes encastes de Cebú x Holstein x Simmental con un peso promedio de 230,5 kg en pastoreo rotacional con cerco eléctrico y pasto estrella ( Cynodon nlemfuensis check for this species in other resources ). El experimento tuvo un diseño completamente al azar, con cuatro tratamientos y cinco repeticiones por tratamiento: T1: Pastoreo (testigo), T2: Pastoreo + alimento comercial, T3: Pastoreo + bloques multinutricionales y T4: Pastoreo + follaje de cocoite. La evaluación se llevó a cabo en 56 días, más 10 de adaptación. El consumo se calculó con la diferencia de lo ofrecido y lo rechazado. Se utilizó un DCA con análisis de varianza y una prueba de medias corregida por covariable de peso inicial, para la ganancia de peso. Las ganancias diarias de peso obtenidas fueron 0,664 1,071 0,767 y 0,617 kg/animal para T1, T2, T3 y T4, respectivamente. El costo de suplementación por animal fue de 1,4 0,05 y 0,49 USD para T2, T3 y T4. Los resultados anteriores indican el potencial de los BMN para ser incorporados en los sistemas de engorda de toretes en pastoreo.

Palabras-clave
ganancia de peso, bloques multinutricionales, follaje de cocoite, toretes en pastoreo.
