Impact of LEP and LEPR gene polymorphisms on functional traits in Polish Holstein-Friesian cattle
Journal Title: Animal Science Papers and Reports - Year 2010, Vol 28, Issue 2
Abstract
Five single nucleotide polymorphisms in leptin and leptin receptor genes were analysed for their possible impact on estimating breeding values for somatic cell count score (SCS) in milk, longevity and reproductive traits. Used were 309 active Polish Holstein-Friesian bulls. The LEP-C(-963)T, LEP-Y7F, LEP-R25C, LEP-A80V, and LEPR-T945M genotypes were identified using the PCRRFLP method. For linked leptin mutations, the additional haplotype analysis was performed. The results obtained suggest that three polymorphisms of bovine LEP gene may be associated with nonreturn rate in cows. The most significant effect was found for LEP-A80V. Moreover, the LEPRT945M mutation seemed to be related to the age at first insemination.

Influence of selected factors upon the blood loss from the carcasses of pigs free of the stress susceptibility gene (RYR1T)
The aim of the study was to determine the effect of road transport, lairage time, meat % and carcass weight, sex, and PPARGC1A gene polymorphism on the degree of blood loss after slaughter. The study was conducted on 350...
Application of chicken microsatellite markers to molecular monitoring of the experimental population of Japanese quail (Coturnix japonica)
Chromosome homology is highly conserved between chicken (Gallus gallus) and Japanese quail (Coturnix japonica) and a few chromosome rearrangements occurred in the evolution of these two species. Microsatellite markers ar...
