Abstract

This study aimed to determine the trends in milk production, fertility, temperature-humidity index (THI), and herd size in dairy herds from the Laguna region in northern Mexico. Records of 16 dairy herds of Holstein cows from January 2002 to December 2016 were used. Milk production was categorized...

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

Reproductive biotechnologies are used for the conservation, expansion and genetic improvement of cattle, and to facilitate the creation of germplasm banks of elite animals and endangered breeds. The objective of this study was to compare the effects of two different doses of follicle stimulating...

Abstract

Yield, chemical composition, fatty acid profile, and sensory acceptability of Panela cheese produced from cows grazing in an intensive silvopastoral system (ISS) with Leucaena leucocephala and Cynodon nlemfuensis were evaluated and compared with Panela cheese from cows grazing a monoculture system...

Abstract

Several studies suggest that reproductive performance in small-scale dairy farms is low reducing the farms' profitability. Therefore, identifying risk factors associated with low reproductive performance is a key step to implement an improved reproductive management program. Accordingly, the aim of ...

Abstract

In the semi-arid highlands of central Mexico, triticale (× Triticosecale L.) is emerging as an alternative, less water-demanding forage crop than alfalfa for dairy cattle. Studies reported here were aimed at evaluating triticale hay (TH) relative to alfalfa hay (AH) for lactating cow performance,...

AbstractFull Text

The objective was to assess the effect of different access times to pasture of grazing dairy cows on milk yield and fatty acid (FA) profile. Six multiparous Holstein cows were used in a repeated 3x3 Latin Square design. Treatments were (1) Eight hours of grazing (8h), (2) Eight hours of grazing...

Abstract

The objective was to estimate a production function that describes the relationship between production and milk production factors in the dual purpose bovine system in the municipality of Ahome, Sinaloa. With information from 74 production units a Cobb Douglas production function was estimated. The ...
