Genomic data Genotypes for about 40,000 single nucleotide polymorphisms (SNP) now act as a third source of data for national genetic evaluations of dairy cattle, in addition to phenotypes and pedigrees that were the basis of selection for the previous 100 years. Rapid developments in genotyping tools have lowered the cost of obtaining this genomic data to just over $200 per animal. The Illumina...

Livestock keepers in southwestern Burkina Faso hold the local Lobi taurine breed, Zebu cattle, and their crosses. Some communities region have begun to implement community-based cattle breeding programs (CBBPs), which involve animal tagging recording and, potentially, also bull sharing. Based on hypothesis that participation of livestock CBBPs depends attitudes towards these programs, we used q...

The purpose of this study is to identify pathological findings among pigeon breeders in the Salonica area. Fifty-four volunteer breeders with varying intensity of contact with pigeons participated in the study. All the breeders, after filling in a questionnaire that included questions about the existence of conjunctivitis, rhinitis, chronic cough and sputum, were subjected to clinical examinati...

Coastal cattle are livestock that have economic value, such as selling beef and breeds. Cow disease can cause the quality of its sales to decrease. This study aims help breeders determine type cow disease, from symptoms exist in these cows. So prevention risk be avoided. All data used sourced experts. In determining cows, Forward Chaining method is used. The fact-finding technique then put into...

Pathology data have been reported to be important for surveillance, as they are crucial correctly recognizing and identifying new or re-emerging diseases in animal populations. However, there no reports the literature of necropsy being compared complemented with other data. In our study, we cattle extracted from 3 laboratories Swiss fallen stock clinical collected by association Cattle Breeders...

Implementation of genomic selection in sheep breeding provides a number of challenges, compared to dairy cattle, because of the higher genetic diversity between and within sheep breeds, the cost of maintaining reference populations and the limited ability of individual breeders to invest in genotyping. Within this study, we compare theoretical and realized genomic prediction accuracies for trai...

To investigate the congenital complex vertebral malformation syndrome (CVM) in Holstein calves, two breeding studies were performed including 262 and 363 cows, respectively. Cows were selected from the Danish Cattle Database based on pedigree and insemination records. Selected cows were progeny of sires with an established heterozygous CVM genotype and pregnant after insemination with semen fro...
