Genomic Diversity of U.S. Katahdin Hair Sheep. [PDF]
J Anim Breed GenetABSTRACTIn the late 1950s, Katahdin hair sheep were developed as a composite breed of medium size and moderate prolificacy, with potential to express resistance to gastrointestinal nematodes. With increasing popularity and the recent adoption of genomic prediction in their genetic evaluation, there is a risk of decreasing variation with selection based

Strategic vaccination of hair sheep against Haemonchus contortus
Parasitology Research, 2019 In this study, we evaluated in two trials a protocol designed to protect hair sheep using Barbervax®, a vaccine containing Haemonchus contortus gut membrane glycoprotein antigens. Results indicated that naturally infected vaccinated sheep had significant egg count reductions (90.2 ± 4.03%) compared with controls, although blood parameters remained ...

Transcriptome Analysis Reveals Candidate Genes Regulating the Skin and Hair Diversity of Xinji Fine-Wool Sheep and Tan Sheep [PDF]
Agriculture, 2021 The hair follicle is a complex mini-organ in the skin that undergoes organ induction, morphogenesis, and regeneration. However, the accurate molecular mechanism of skin and hair diversity regulation is still elusive. The sheep is an animal model that can

Heat tolerance in Brazilian hair sheep
Asian-Australasian Journal of Animal Sciences, 2016 The aim of this study was to evaluate heat tolerance using heat tolerance indices, physiological, physical, thermographic, and hematological parameters in Santa Ines and Morada Nova sheep breeds in the Federal District, Brazil.Twenty-six adult hair sheep, one and a half years old, from two genetic groups (Santa Ines: 12 males and 4 females; Morada Nova:

EVALUATION OF MODELS TO ESTIMATE EMPTY BODY WEIGHT IN HAIR SHEEP RAISED IN A FEEDLOT SYSTEM
Tropical and Subtropical Agroecosystems, 2022 Background. The empty body weight (EBW) represents exactly the animal mass and is used as a base to calculate most of the nutrient requirements in most feeding systems. Objective.

Prediction of Carcass Traits of Hair Sheep Lambs Using Body Measurements. [PDF]
Animals (Basel), 2020 The present study was designed to evaluate the relationship between the body measurements (BMs) and carcass characteristics of hair sheep lambs. Twenty hours before slaughter, the shrunk body weight (SBW) and BMs were recorded. The BMs involved were height at withers (HW), rib depth (RD), body diagonal length (BDL), body length (BL), pelvic girdle ...

'Meta-analysis of dry matter intake and neutral detergent fiber intake of hair sheep raised in tropical areas'. [PDF]
PLoS ONE, 2020 Inadequate estimates of fiber and dry matter intake of sheep raised in tropical conditions may explain part of the inefficiency of those production systems. Therefore, we aimed to estimate dry matter intake (DMI) and neutral detergent fiber intake (NDFI)
