Estimation of crossbreeding and genetic parameters for reproductive traits of Boer x Central Highland goats in Ethiopia.

PLoS ONE, 2023
Additive genetic and non-additive parameters for reproductive traits of Boer x Central Highland goats were estimated. Pedigree and performance records comprised of Central Highland and their crosses with Boer goats were collected from 2009 to 2018 in the

Leveraging low-density crossbred genotypes to offset crossbred phenotypes and their impact on purebred predictions

Journal of Animal Science, 2022
The objectives of this study were to 1) investigate the predictability and bias of genomic breeding values (GEBV) of purebred (PB) sires for CB performance when CB genotypes imputed from a low-density panel are available, 2) assess if the availability of

Carcass characteristics of cattle differing in Jersey proportion [PDF]

, 2018
peer-reviewedComparison of alternative dairy (cross-)breeding programs requires full appraisals of all revenues and costs, including beef merit. Few studies exist on carcass characteristics of crossbred dairy progeny originating from dairy herds as well ...

Prevalence of and risk factors for degenerative mitral valve disease in dogs attending primary-care veterinary practices in england [PDF]

, 2015
Background To date, epidemiological studies on degenerative mitral valve disease (DMVD) in dogs have largely reported referral caseloads or been limited to predisposed breeds.

PSV-16 Validation of an algorithm to assess feedbunk replacement events in beef cattle using an electronic feeding system

Journal of Animal Science, 2021
Visual observations of social behavior and dominance relationships in cattle have been used to examine associations with productivity and well-being. This method is time consuming limiting the number of animals that can be evaluated.

The inheritance of fibre traits in a crossbred population of cashmere goats [PDF]

, 1996
Genetic parameters were calculated for fibre traits measured on patch samples taken at 5 months of age on a crossbred population of cashmere goats, comprising goats of Scottish feral, Icelandic, Tasmanian, New Zealand and Siberian origin.

Haplotype inference in crossbred populations without pedigree information

Genetics Selection Evolution, 2009
Background Current methods for haplotype inference without pedigree information assume random mating populations. In animal and plant breeding, however, mating is often not random. A particular form of nonrandom mating occurs when parental individuals of

Eimeria species occurrence varies between geographic regions and poultry production systems and may influence parasite genetic diversity [PDF]

, 2017
Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in

A comparison of alternative methods to compute conditional genotype probabilities for genetic evaluation with finite locus models

Genetics Selection Evolution, 2003
An increased availability of genotypes at marker loci has prompted the development of models that include the effect of individual genes. Selection based on these models is known as marker-assisted selection (MAS). MAS is known to be efficient especially
