Breeding goals in pigs are subject to change and directed much more toward retail carcass yield meat quality because of the high economic value these traits. The objective this study was estimate genetic parameters growth, carcass, Carcass components included ham loin weights as primal cuts, which were further dissected into boneless subprimal cuts. Meat traits pH, drip loss, purge, firmness, color marbling both loin. Phenotypic measurements collected on a commercial crossbred pig population...
The objective of the present experiment was to study physiological changes elicited in response stress immediate preslaughter period and link them pork quality characteristics. Crossbred, halothane-free pigs (n = 192) were processed eight groups (24 per group) on various days at one two commercial processing plants operating different stunning systems (electrical CO2 Plants A B, respectively). In each group, half exposed either minimal or high stress. Blood samples taken exsanguination,...
Osteochondrosis (OC) is the most important orthopaedic developmental disorder in horses and may manifest several different forms. No detailed study on prevalence and/or interrelation of these forms available, even though data are a prerequisite for conclusive genetic studies.To assess various manifestations OC as detected radiographically to evaluate possible relationships between their occurrence within same joint joints.The FP (femoropatellar), TC (tarsocrural) MCP/MTP...
Abstract Objective —To determine incidence, risk factors, and heritability estimates of hind limb lameness caused by hip dysplasia in a birth cohort Boxers. Animals —1,733 Boxers from 325 litters. Procedure —Status with respect to clinical signs canine (cCHD) was registered during an 8-year period. Survival analysis accounted for dogs lost follow-up. Effective developing cCHD estimated use proportional hazard model on the basis Weibull distribution. Parametric survival models were developed...
The objective of the current study was to estimate genetic and phenotypic correlations among feather pecking (FP) behavior stress response, immune egg quality parameters. These traits have been measured in an F2 cross, coming from a cross between high low FP line laying hens. Heritabilities (h2) response (32 wk), primary keyhole limpet hemocyanin (KLH) (36 wk) Mycobacterium butyricum (39 parameters (35, 44, 50 wk age) were calculated. h2 0.05 ± (SE) for 0.15 0.07 antibody KLH, 0.08 0.06 M....
Summary Reasons for performing study : It is expected that climate and habitat factors influence the prevalence of culicoides and, therefore, insect bite hypersensitivity (IBH), but very little described in literature to prove association these factors. Prevalence varies widely from 3% certain areas Great Britain 60% parts Australia. Objectives To describe environmental on IBH Shetland ponies Friesian horses Netherlands. Methods Data 3284 2824 mares (n = 6108) were collected Netherlands,...
Insect bite hypersensitivity is a common allergic disease in horse populations worldwide. affected by both environmental and genetic factors. However, little known about genes contributing to the variance associated with insect hypersensitivity. Therefore, aim of our study was identify quantify genomic associations Shetland pony mares Icelandic horses Netherlands.Data on 200 146 were collected according matched case-control design. Cases controls various factors (e.g. region, sire) minimize...
Turkey is an important agricultural species and largely used as a meat bird. In 2004, turkey represented 6.5% of the world poultry production. The world-wide population has rapidly grown due to increased commercial farming. Due high demand for from both consumers industry global stocks 100 million in 1970 over 276 2004. This increasing importance turkeys was reason design this study estimation genetic parameters that control body weight, composition, quality traits shape growth curve birds....
Summary The recent completion of the horse genome and commercial availability an equine SNP genotyping array has facilitated mapping disease genes. We report putative localization gene responsible for dwarfism, a trait in Friesian horses that is thought to have recessive mode inheritance, 2‐ MB region chromosome 14 using just 10 affected animals controls. successfully genotyped 34 429 SNPs were tested association with dwarfism chi‐square tests. most significant our study, BIEC2‐239376 ( P...
Inbreeding and population bottlenecks in the ancestry of Friesian horses has led to health issues such as dwarfism. The limbs dwarfs are short ribs protruding inwards at costochondral junction, while head back appear normal. A striking feature condition is flexor tendon laxity that leads hyperextension fetlock joints. growth plates display disorganized thickened chondrocyte columns. aim this study was identify gene defect causes recessively inherited trait understand disease process...
While susceptibility to hypersensitive reactions is a common problem amongst humans and animals alike, the population structure of certain animal species breeds provides more advantageous route better understanding biology underpinning these conditions. The current study uses Exmoor ponies, highly inbred breed horse known frequently suffer from insect bite hypersensitivity, identify genomic regions associated with type I IV reaction. A total 110 cases 170 controls were genotyped on 670K...
Abstract Background The effect of heat stress on livestock production is a worldwide issue. Animal performance influenced by exposure to harsh environmental conditions potentially causing genotype-by-environment interactions (G × E), especially in highproducing animals. In this context, the main objectives study were (1) detect time periods which heifer fertility traits are more sensitive high temperature and/or humidity, (2) investigate G E due traits, and, (3) identify genomic regions...
ABSTRACT Holstein cattle account for the largest proportion of dairy in China. The current China Performance Index (CPI) consists mainly production traits. To derive economic values (EV) additional traits balanced breeding programs, a bio‐economic model is necessary. Landless and intensive farms are dominant China, wherein all feed purchased, in‐farm technicians veterinarians employed. Therefore, present study, tailored was developed using parameters typical farm North had 1500 cows 1400...
Hydrocephalus in Friesian horses is a developmental disorder that often results stillbirth of affected foals and dystocia dams. The occurrence probably related to founder effect inbreeding the population. aim our study was find genomic associations, investigate mode inheritance, allow DNA test for hydrocephalus be developed. In case monogenic inheritance we aimed identify causal mutation. A genome-wide association 13 cases 69 controls using 29,720 SNPs indicated involvement region on ECA1 (P...
Many common and relevant diseases affecting equine welfare have yet to be tested regarding structural variants such as copy number variations (CNVs). CNVs make up a substantial proportion of total genetic variability in populations many species, resulting more sequence differences between individuals than SNPs. Associations disease phenotypes been established several but CNV studies limited. Aim this study was identify perform genome-wide association (GWA) Friesian horses genomic loci...
Most breeding companies evaluate economically important traits in males and females as a single trait, assuming genetic correlation of 1 between phenotypes measured both sexes. This assumption may not be true because genes differently expressed females. We estimated correlations for growth efficiency broiler chickens, American Angus beef cattle, birth weight preweaning mortality purebred pigs; therefore, each trait was treated Variance components were single- multiple-trait models, jointly...
