The Bovine Respiratory Disease Complex Coordinated Agricultural Project (BRD CAP) is a 5-year USDA-funded Coordinated Agricultural Project to develop genetic markers associated with bovine respiratory disease (BRD) to identify cattle that are less susceptible to BRD. Ultimately the aim of this project is to integrate predictive markers for BRD susceptibility into genetic tests and national catt...
BACKGROUND Breeds with small population size are in danger of an increased inbreeding rate and loss of genetic diversity, which puts them at risk for extinction. In Sweden there are a number of local breeds, native breeds which have adapted to specific areas in Sweden, for which efforts are being made to keep them pure and healthy over time. One example of such a breed is the Swedish Gute sheep...
Abstract The chemical composition of goat milk, especially fatty acid profile is recently renewed due to the role monosaturated and polyunsaturated acids in human nutrition. These nutrients are important analysed connection with different breeds receiving same breeding feed. aim this study was analyse milk relation breeds. Specimens for analyses were collected from individual animals like Latvi...
The goal of this study was to assess SARS-CoV-2 seroprevalence in pet dogs and cats during the coronavirus disease (COVID-19) pandemic Iraq. Serum samples were collected from 180 animals, including 96 84 cats. All animals included owned a household with at least one COVID-19 patient. screened for antibodies against using commercial ELISA assay (ID Screen® Double Antigen Multi-species) according...
Genomic structural variation is an important and abundant source of genetic and phenotypic variation. Here, we describe the first systematic and genome-wide analysis of copy number variations (CNVs) in modern domesticated cattle using array comparative genomic hybridization (array CGH), quantitative PCR (qPCR), and fluorescent in situ hybridization (FISH). The array CGH panel included 90 animal...
The International Society of Animal Genetics (ISAG) has chosen nine microsatellites (international marker set) as a standard that should be included in all cattle parentage studies. They are BM1824, BM2113, INRA023, SPS115, TGLA122, TGLA126, TGLA227, ETH10, and ETH225. We decided to ascertain whether this microsatellite set could be used to determine ancestral proportions in individual animals ...
The aim of this study was to obtain unbiased estimates of the diversity parameters, the population history, and the degree of admixture in Cika cattle which represents the local admixed breeds at risk of extinction undergoing challenging conservation programs. Genetic analyses were performed on the genome-wide Single Nucleotide Polymorphism (SNP) Illumina Bovine SNP50 array data of 76 Cika anim...
Male reproductive performance has more impact on overall herd productivity than in the female. In order to assess herd productivity in cattle in Nyagatare, Eastern Rwanda, the proportional distribution of male reproductive organ abnormalities was investigated in 3087 bulls slaughtered over a 4-year period. The aim of the study was to investigate the proportional distribution of male reproductiv...
The objective this study was to evaluate the effects of incidence of bovine respiratory disease (BRD) and overall incidence of pathogenic diseases (IPD) on carcass traits. Two independent populations were used. The first population included crossbred steers (GPE7; n = 642) derived from sires of 7 Bos taurus breeds: Angus, Charolais, Gelbvieh, Hereford, Limousin, Red Angus, and Simmental. The se...
Estimating the energy expenditure of farm animals at pasture is important for efficient animal management. In recent years, an alternative technique for estimating energy expenditure by measuring body acceleration has been widely performed in wildlife and human studies, but the availability of the technique in farm animals has not yet been examined. In the present study, we tested the potential...
