Ambiente ruminal, consumo, digestión y metabolismo del nitrógeno en bovinos alimentados con niveles de Leucaena
El objetivo del estudio fue evaluar indicadores del ambiente ruminal, consumo, digestión y metabolismo del N en bovinos alimentados con niveles crecientes de L. leucocephala y pasto P. purpureum. Se utilizaron cuatro vacas ... -
Comportamiento productivo de vacas cruzadas en un sistema de doble propósito en Yucatán, México
Se analizó la información de producción y reproducción de vacas con 50 y 75% de genes Holstein, manejados en hatos de doble propósito en Yucatán, México. El trabajo consistió en un estudio retrospectivo de 222 lactancias ... -
Consumo de mimosina en el desarrollo de glándulas endometriales de vacas en postparto temprano
Leucaena leucocephala es un arbusto rico en proteína y mimosina que se cultiva en altas densidades para incrementar la ingesta de proteína en sistemas de producción bovina. La mimosina es un antimitótico cuyo efecto sobre ... -
Effect of dried leaves of Leucaena leucocephala on rumen fermentation, rumen microbial population, and enteric methane production in crossbred heifers
The objective of the experiment was to evaluate the effects of dietary supplementation of heifers with increasing levels of dried Leucaena leucocephala leaves (DLL) on nutrient digestibility, fermentation parameters, ... -

Evaluation of milk composition and fresh soft cheese from an intensive silvopastoral system in the tropics
Intensive silvopastoral system (ISS) is a successful sustainable grazing system for dual-purpose cattle with growing adoption in the tropics; however, there is a concern on the quality of dairy products from this system. ... -
Fatty acids profile of fresh cheese produced in an intensive silvopastoral system in the tropics
Intensive silvopastoral systems are being increasingly disseminated in the tropical areas of Mexico, Central and South America, so it is important to know the quality of the animal products generated in these systems. Fatty ... -

Leucaena leucocephala feeding systems for cattle production in Mexico
The impacts of leucaena (Leucaena leucocephala) feeding systems on cattle production, environmental services and animal welfare in Mexico are discussed. A total of about 12,000 ha of leucaena have been established in the ... -
Manipulation of the energy metabolism of ruminants in the tropics: options for improving meat and milk production and quality
Ruminant feeding in tropical regions is characterized by grass grazing. Throughout the year, grasses show variations in their availability and quality. Therefore, modern feeding systems must consider the energy requirements ... -
