Livestock production in Latin America is strongly associated with deforestation. Silvopastoral systems are an alternative; however, the relation between animal welfare and tree coverage has been poorly studied. We hypothesized that a connection between these features exist and that its evaluation...

Abstract

The aim was to study postpartum follicular population dynamics in Brahman cows in the Mexican humid tropics and under different stocking rates. Lactating adult cows (n=104) grazed native grammas (Paspalum spp., Axonopus spp.) under two stocking rates: 2.8 (high) or 1.7 (low) cows/ha. Follicle...

Abstract

Tropical grasses are the primary nutrient resource for cattle production in the tropics, and they provide low-cost nutrients to cattle. However, its production is constrained by seasonal changes and quality; hence, appropriate usage of relatively inexpensive agricultural by-products is important to ...

Abstract

A herd was monitored for two years in order to determine the effect of body condition score on the reproductive performance of Zebu cows managed under continuous mating in the tropics of México. Overall cyclicity and pregnancy rates were 60.5% and 37.1% at four months postpartum, respectively. 62.9 ...
