Using a multi-breed reference population might be way of increasing the accuracy genomic breeding values in small breeds. Models involving mixed-breed data do not take into account fact that marker effects may differ among This study was aimed at investigating impact on number genotyped candidates training set by using population, contrast to single-breed evaluations. Three traits (milk production, fat content and female fertility) were analyzed mixed linear models Bayesian methodology....

Abstract Background As consumers continue to request food products that have health advantages, it will be important for the livestock industry supply a product meet these demands. One such nutrient is fatty acids, which been implicated as playing role in cardiovascular disease. Therefore, objective of this study was determine extent molecular markers could account variation acid composition skeletal muscle and identify genomic regions harbor genetic variation. Results Subsets on Illumina...

This paper aimed at investigating the potential use of sperm DNA fragmentation (SDF) to improve routine screening infertility Holstein bulls. Cryopreserved samples from 201 bulls provided by an AI center were used in analyses SDF 0 (SDF_0) and 6 (SDF_6) h incubation 37°C. A refinement chromatin dispersion test implemented Sperm-Halomax kit was employed measure SDF. Records on routinely collected semen traits (volume, concentration, mass individual motility evaluated fresh ejaculate,...

Transmission ratio distortion (TRD) is the departure from expected Mendelian in offspring, a poorly investigated biological phenomenon livestock species. Given current availability of specific parametric methods for analysis segregation data, this study focused on screening TRD 602 402 single nucleotide polymorphisms covering all autosomal chromosomes seven Spanish beef cattle breeds. On average, 0.13% (n = 786) and 0.01% 29) genetic markers evidenced sire- or dam-specific respectively....

Data from 4049 Romanov sheep belonging to a flock affected by natural scrapie were analysed using survival-analysis techniques. Failure time was defined as the period of between first exposure infection and date that animals left with signs. Four hundred forty-seven identified ‘scrapie animals’. Several models, including level time-dependent effect, PrP genotype, sex, age at exposure, litter size factors related vertical transmission, tested. The best model extended sire–dam frailty model,...

The availability of SNP chips for massive genotyping has proven to be useful genetically characterize populations domestic cattle and assess their degree divergence. In this study, the Illumina BovineHD BeadChip array was used describe genetic variability divergence among 7 important autochthonous Spanish beef breeds. within-breed diversity, measured as marker expected heterozygosity, around 0.30, similar other European analysis molecular variance revealed that 94.22% total explained by...

Procedures for the detection of signatures selection can be classified according to source information they use reject null hypothesis absence selection. Three main groups tests identified that are based on: (1) analysis site frequency spectrum, (2) study extension linkage disequilibrium across length haplotypes surround polymorphism, and (3) differentiation among populations. The aim this was compare performance a subset these procedures by using dataset on seven Spanish autochthonous beef...

Within the EURECA project (Towards self-sustainable EUropean REgional CAttle breeds), we interviewed a total of 371 farmers 15 local cattle breeds in eight European countries. Besides collecting data on farmers, land use, herd composition and economic role cattle, aimed at understanding farmers' motives values keeping cattle. The most frequent first reason to keep breed was productivity, followed by tradition. When comparing with mainstream breed, only four productivity considered same,...

While physiological differences across skeletal muscles have been described, the differential gene expression underlying them and discovery of how they interact to perform specific biological processes are largely be elucidated. The purpose present study was, firstly, profile by cDNA microarrays between two muscle types, Psoas major (PM) Flexor digitorum (FD), in beef cattle then interpret results context a bovine coexpression network, detecting possible changes connectivity system.

Summary Recognizing cultural diversity among local breed farmers is crucial for the successful development and implementation of farm animal genetic resources FAnGr conservation policies programmes. In this study based on survey data collected in EUropean REgional CAttle breeds project from six European countries, a typology was designed profiles each farmer types were developed to assist these policy needs. Three main constructed: production‐oriented, product service‐oriented hobby‐oriented...

Genetic Analyses in large sample populations are important for a better understanding of the variation between populations, designing conservation programs, detecting rare mutations which may be risk factors variety diseases, among other reasons. However these analyses frequently assume that participating individuals or animals mutually unrelated not case samples, leading to erroneous conclusions. In order retain as much data possible while minimizing false positives it is useful identify...

Livestock breed-related public good functions are often used to justify support for endangered breed conservation despite the fact that little is known about such non-market values. We show how stated preference techniques can be assess values people place on livestock breeds. Through application of a case study choice experiment survey in Zamora province, Spain, total economic value (TEV) threatened Alistana–Sanabresa (AS) cattle was investigated. An analysis relative importance components...

SWOT (Strengths, Weaknesses, Opportunities and Threats) analysis is a tool widely used to help in decision making complex systems. It suits exploring the issues measures related conservation development of local breeds, as it allows integration many driving factors influencing breed dynamics. We developed quantified method decision-making for identification ranking strategies applied set 13 cattle breeds six European countries. The has four steps: definition system, grouping factors,...
