Fighting Behavior Isolation Test Skin Lesion Score Heart Rate Variability Autonomic Nervous System
2017/3/9
The objective of this study was to investigate the effect of 20-day litter weight on behavior and heart rate variability (HRV) of piglets under stress.
Expression analysis of the porcine Homeobox A11 gene and its association with litter size in Large White pigs
endometrium HOXA11 qPCR single nucleotide polymorphism litter size
2016/6/3
The homeobox A11 (HOXA11) gene, a well-known transcriptional regulator, plays a critical role in normal development of the uterus. In this study, the porcine HOXA11 gene, including its promoter region...
Breeding value evaluation in Polish fur animals: Estimates of direct heritability and portion of litter variation of fur coat and reproduction traits
arctic fox fur coat heritability
2015/6/1
The study presents estimates of heritability for fur coat and reproduction traits in arctic and silver foxes kept on Polish farms. The estimates of variance components were calculated using the DFREML...
Genetic parameters for litter size in Black Slavonian pigs
multiple trait model random regression model
2014/10/23
The objective of this study was to estimate genetic parameters for litter size of Black Slavonian pigs using the repeatability, multiple trait, and random regression models, and to consider the possib...
Prolificacy and Its Relationship with Age, Body Weight, Parity, Previous Litter Size and Body Linear Type Traits in Meat-type Goats
Goat, Black Bengal Prolificacy Linear Type Traits Litter Size Pregnancy
2016/5/16
Data on age and body weight at breeding, parity, previous litter size, days open and some descriptive body linear traits from 389 meat-type, prolific Black Bengal goats in Tripura State of India, were...
Influence of Rabbit Sire Genetic Origin, Season of Birth and Parity Order on Doe and Litter Performance in an Organic Production System
Rabbit Organic Production System Reproduction Genetic Origin
2016/5/11
The aim of this study was to compare both the performance of litters derived from two sire genetic origins (SGO), Vienna Blue (VB) and Burgundy Fawn (BF), along successive seasons of birth (SB; winter...
Association of Polymorphisms in Fecundity Genes of GDF9, BMP15 and BMP15-1B with Litter Size in Iranian Baluchi Sheep
BMP15 BMP15-1B GDF9 Litter Size Baluchi Sheep
2016/5/6
The incidence of mutation in three loci of GDF9, BMP15 and BMP15-1B and their effects on litter sizes was evaluated in Baluchi sheep. Wild-type alleles were detected for BMP15 and BMP15-1B loci and al...
Genetic parameters for Finnish blue fox population: litter size, age at first insemination and pelt size
fertility fur animals genetic correlations heritability pelt size variance components
2010/8/9
Pelt size has increased rapidly in the Finnish blue fox population during the last decade. However, average number of pups per mated female has slightly decreased after the mid-1990抯. In this study we...
Oviduct-specific Glycoprotein 1 Locus is Associated with Litter Size and Weight of Ovaries in Pigs
Oviduct-specific Glycoprotein 1 Litter Size Female Reproductive Tract Components Pigs
2016/4/21
Oviduct-specific glycoprotein 1 (OVGP1) is implicated in playing a role in fertilization and early embryo development. In this study, we have obtained the sequence of intron 9 of OVGP1 gene in swine. ...
