Increasing productivity is one of the main objectives in animal production. Traditional
breeding methods have led to increased gains in some traits but gains are not easily …

Fat affects meat quality, value and production efficiency as well as providing energy
reserves for pregnancy and lactation in farm livestock. Leptin, the adipocyte product of the …

Background Leptin modulates appetite, energy expenditure and the reproductive axis by
signalling via its receptor the status of body energy stores to the brain. The present study …

RFLP method. For linked leptin mutations, the additional haplotype analysis was performed.
The results obtained suggest that three polymorphisms of bovine LEP gene may be …

In order to detect polymorphism in TGF-b3 loci and effect of this gene on phenotypic and
breeding values of body weight traits, blood samples were collected randomly from 120 …

The aim was to investigate the effect of the genetic polymorphisms of leptin (LEP) and
stearoyl-CoA desaturase (SCD1) genes on the fatty acid (FA) composition of the muscle of …

Leptin is the hormone product of the obese gene and is synthesized and secreted
predominantly by white adipocytes and relates to the feedback system that regulates long …

In this work, the genetic variation of milk FA was investigated in three different bovine
breeds, the Jersey, the Piedmontese and the Valdostana, and at different lactation stages …

HIGHLIGHTS The CC genotype of the LEP gene decreases 28.71 days of the calving to
conception interval. The AA genotype of the Pit-1 gene decreases 41.36 days the age at first …

The aim of the study was to analyse the relationship between the Arg4Cys and Ala59Val
polymorphisms of the bovine leptin gene, and the milk traits, based on the breeding values …
