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...

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 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 tropical regions of México, where most of the information for the current...

Abstract

This study investigated exposure to gastrointestinal (GI) nematodes on dairy cattle farms by antibody level determination in bulk tank milk (BTM) samples and its influence on production to detect the risk factors for infection in different climate regions in three states of Mexico. From January to...

Abstract

In order to estimate the genetic parameters and correlations between total lactation milk yield and growth traits in a multiracial population of dual purpose cattle in tropical environments of Mexico, genetic variances and covariances were estimated between total milk yield during the first (PTL1...

Abstract

Background: A concern for breeders is whether an animal ranking based on genetic evaluations is similar to that obtained from show-ring judging. Objective: to determine the association between rankings for Braunvieh (BR) and Brown Swiss (BS) cattle of Mexico based on show-ring judging and their...

Abstract

In a first study, 231 cows with retained placenta (RP) were assigned to four groups and their reproductive performance after treatment was studied. Group 1 received 2.0 mg/kg ceftiofur hydrochloride (CH), 10 mg estradiol cypionate (ECP) and 100 IU oxytocin for three consecutive days (CEO-3; n=63)....
