A total of 185 German Pomeranian Coarsewool (RPL) sheep were genotyped to evaluate their genetic diversity and assess the possibility of breeding for resistance against maedi-visna virus (MVV).  Breeding for MVV resistance is feasible without reducing genetic diversity, but it is not recommended until further studies confirm the protective effect of theTMEM154 allele K against MVV in this breed. This study pioneers research on selective breeding for disease resistance.

The objectives of this study are to identify a suitable mathematical model for determining the breeding strategies and describing the growth curve of the Kaçkar hair goat.

The pre-weaning and weaning traits of sheep breeds native to Türkiye were studied. The rs427117280 intronic mutation in ENSOARG00020011332 was associated with the weaning weight and average daily gain until weaning in lambs. The weaning weight and average daily gain were higher for the GG genotype than for the TG and TT genotypes.

A mutation in the thioesterase domains of the fatty acid synthase enzyme reduces the percentage of myristic acid. In silico simulations were performed to assess the mutation's impact on the catalytic site's affinity for ligands and its effect on intramuscular fatty acid profiles. Tertiary structures were generated, revealing increased affinity between the mutated enzyme and myristoyl. However, the structural changes have a more significant impact on the fatty acid profile than the altered affinity.

Cameroon local pigs are out-bred and neglected ecotypes, with a consistent variation in coat colours and colour patterns. The phenotypic diversity is an asset for selective breeding and genetic improvement. But it is challenging for accurate information sharing for breed utilisation, improvement and conservation perspectives. This study aimed to describe the genetic resources of pigs and to develop a standard protocol for phenotypic information sharing with the global scientific audience.
