Genetic aspects of calving, growth, and carcass traits in beef cattle [PDF]

open access: yes, 2003
The aim of this thesis was to learn more about the genetic background of calving, growth and carcass traits of beef cattle breeds in Sweden, and to assess the possibility of including calving traits and commercial carcass traits in the genetic evaluation.

Factors influencing survival of rescued Amazonian manatees (Trichechus inunguis) during clinical rehabilitation in Peru

open access: yesConservation Science and Practice, EarlyView.
The Amazonian manatee (Trichechus inunguis) faces threats like habitat loss, illegal hunting, and pollution. Our analysis of 54 rescued manatees in a Peruvian Amazon rehabilitation center revealed that initial weight and rate of weight gain significantly influenced survival during rehabilitation, while intestinal obstruction, often from prior ...

Drying off the dairy cow [PDF]

open access: yes, 2006
Most dairy cows generally have a non-lactating, “dry period” prior to parturition. As the milk production of dairy cows has increased dramatically during the last decades, cows managed conventionally with a 12 to 13 month-calving interval are dried off ...

CALVING INTERVAL IN NELORE CATTLE

open access: yes, 2007
The work presents the study of 368 calving intervals data in Nelore cattle of Goiânia - Goiás. It was observed that the average calving intervals were 16.15 +/- 0.22 months.

Plasma C‐reactive protein and interleukin‐6 concentrations in foals during health and respiratory disease

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Early and specific diagnosis of bronchopneumonia in foals is important to prevent severe disease. In human medicine, C‐reactive protein (CRP) and interleukin‐6 (IL‐6) are important diagnostic and prognostic biomarkers in neonatal pneumonia in other species.

Unravelling Twin Births in German Holstein Cows: Phenotypic Associations, Genetic Analysis and Potential Underlying Genes and Hormones

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Twin births in dairy cattle are rare but present significant challenges for animal welfare, as both the health of the cow and the calves are affected. This causes economic losses, which prompts breeders to select against twin births and identify associated risk factors.

Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.
