Studied traits were litter size at birth (LSB), litter size at weaning (LSW), litter mean weight per lamb born (LMWLB), litter mean weight per lamb weaned (LMWLW), total litter weight at birth (TLWB...
The melatonin receptors are G protein-coupled receptors (GPCR) that bind melatonin. Three types of melatonin receptors have been cloned. The MTNR1A (or Mel1A or MT1) and MTNR1B (or Mel1B or MT2) recep...
Genetic parameters were estimated for four basic and two composite traits. Year of lambing and age of ewe were used as fixed effects. Due to repeated record of ewe animal direct genetic effect...
Microsatellite FSHBMS polymorphism at the 5’ flanking region of FSHB gene was genotyped and associations with reproductive traits in several pig populations and with reproductive tract components in t...
The experiment involved observations of 2,514 Holstein-Friesian cows to determine the effects of environmental factors (cow’s age, calving season, weight and sex of calves, housing system) and genetic...
Gonadotropin-releasing hormone receptor (GnRHR) gene is expressed at the anterior pituitary gland and plays a key role in gonad development. This study aimed to investigate molecular genetic character...
Establishment of small body size poultry is an important strategy, which leads to effective management of bird-colonies and less feed consumption. And also it would be a useful experimental tool for ...
The objective of this study was to link productive life of Tunisian dairy cows to their performances of milk, fat, and protein yields and fertility traits. Data included 128,652 records collected fr...
We investigated the effect of the prolactin receptor gene (PRLR) on total number of born (TNB), number of born alive (NBA) and number of weaned (NW) piglets in Large White (LW), White Meaty (WM) and L...
We investigated the effect of ESR gene-based selection on an improvement of litter size in the herds in real (non-experimental) conditions. The pigs were selected for three years. In the tested popula...
We investigated the effect of oestrogen receptor (ESR) gene on total number of born (TNB), number of born alive (NBA) and number of weaned (NW) piglets in Large White (LW), White Meaty (WM) and Landra...
The objective of this study was to estimate genetic parameters between first and later parities as different traits in reproductive traits of pigs using multiple trait animal model procedures. Data re...
