Nonlinear models of Brazilian sheep in adjustment of growth curves
body weight Gompertz growth rate mature weight thoracic circumference
2018/11/23
Growth curves of the Morada Nova sheep males and females were described using nonlinear models and the relationships between body weight and thoracic circumference were evaluated. Altogether 1516 repe...
Complete Mitochondrial Genome Sequences of Chinese Indigenous Sheep with Different Tail Types and an Analysis of Phylogenetic Evolution in Domestic Sheep
Mitochondrial DNA Mitogenome Sheep Phylogenetic Mitochondrial Control Region
2016/5/20
China has a long history of sheep (Ovis aries [O. aries]) breeding and an abundance of sheep genetic resources. Knowledge of the complete O. aries mitogenome should facilitate the study of the evoluti...
Targeted Editing of Myostatin Gene in Sheep by Transcription Activator-like Effector Nucleases
Myostatin Targeted Gene Editing Sheep Primary Fibroblasts
2016/5/19
Myostatin (MSTN) is a secreted growth factor expressed in skeletal muscle and adipose tissue that negatively regulates skeletal muscle mass. Gene knockout of MSTN can result in increasing muscle mass ...

Sheep Milk Composition Test Day Model Variance Ratios Heritability Genetic Correlations
2016/5/19
The objective of this study was to assess variance components and genetic parameters for fat and protein content in Tsigai sheep using multivariate animal models in which fat and protein content in in...
Molecular Cloning, mRNA Expression,and Localization of the G-protein Subunit Galphaq in Sheep Testis and Epididymis
Epididymis G-protein Subunit Galphaq [GNAQ] Sheep Testis
2016/12/28
The reproductive function of G-protein subunit Galphaq (GNAQ), a member of the G protein alpha subunit family, has been extensively studied in humans and rats. However, no data is available on its sta...
Inbreeding not to blame for Colorado’s bighorn sheep population decline,CU-Boulder study finds
Inbreeding not to blame Colorado’s bighorn sheep population decline CU-Boulder
2015/8/4
The health of Colorado’s bighorn sheep population remains as precarious as the steep alpine terrain the animals inhabit, but a new study led by researchers at the University of Colorado Boulder has fo...
Activity time budget patterns of sheep and goats co-grazing on semi-natural species-rich dry grassland
animal behaviour activity pattern small ruminant mixed pasture semi-natural grassland
2015/6/24
Activity time budget patterns and grazing response to sward and environmental conditions were investigated for paddocks of sheep and goats co-grazing for conservation purposes on a semi-natural specie...
Analysis of genetic polymorphism in six meat sheep breeds and genetic distances between them
sheep microsatellite DNA genetic polymorphism
2015/6/8
The genomes of 6 sheep populations (Dorset, Texel, Black-Suffolk, Tan sheep, Small-tailed Han sheep, Tan and Small-tailed Han hybrid sheep) were screened using 7 microsatellite DNA markers to estimate...
Asymmetries in Chickens from Lines Selected and Relaxed for High or Low Antibody Titers to Sheep Red Blood Cells
Chicken Asymmetry Selection Wattle Stress
2016/5/17
Wattle length, width, and area were measured to classify bilateral asymmetries in four lines of chickens. The lines were the S26 generation of White Leghorns selected for high (HAS) or low (LAS) respo...
