AbstractFull Text

A total of 245187 records of the first three lactations of 131126 Holstein cows in tropical conditions were used to estimate the genetic (co)variance components between age at calving and its respective milk productions. A multivariate analysis of six traits was performed. Heritability for age at...

Abstract

The aim of the study was to assess milk yields, estimate the intake of crude protein (CP) and determine the concentrations of blood urea nitrogen (BUN) in early post-partum crossbred cows grazing irrigated Leucaena leucocephala (leucaena) in a silvopastoral system relative to those in an irrigated...

Abstract

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. The aim of this study was to compare the ISS with the traditional monoculture...

Abstract

The objective of the study was to determine the effect of routine intramuscular injection of oxytocin to induce milk ejection on behavior assessed in terms of stress and rectal temperature in crossbred cows (Bos indicus × Bos taurus) in the tropics of Veracruz, México. Immediately after calving,...

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 ...
