Background: Fatty acid mobilization and inflammatory response of adipose tissues vary in various depots, hence the response of fat-tailed and thin-tailed sheep breeds to different energy balances was hypothesized to be different due to differences in proportion and metabolism of various adipose depots in these breeds which may affect whole body insulin sensitivity. Objective: Current study aime...

Chinese indigenous sheep can be classified into three types based on tail morphology: fat-tailed, fat-rumped, and thin-tailed sheep, of which the typical breeds are large-tailed Han sheep, Altay sheep, and Tibetan sheep, respectively. To unravel the genetic mechanisms underlying the phenotypic differences among Chinese indigenous sheep with tails of three different types, we used ovine high-den...

Five microsatellite markers were selected for studying the DNA polymorphism of fat-tailed sheep, aiming to understand the genetic diversity of this species. The genetic diversity of five microsatellite markers (BL1038, BM757, BM4621, OarFCB304 and OarFCB48) in fat-tailed sheep population was detected through the native polyacrylamide gel electrophoresis. The results indicated that fat-tailed sh...

Sheep in Ethiopia are adapted to a wide range of environments, including extreme habitats. Elucidating their genetic diversity is critical for improving breeding strategies and mapping quantitative trait loci associated with productivity. To this end, the present study investigated the genetic diversity and population structure of five Ethiopian sheep populations exhibiting distinct phenotypes ...

In the present study, the effect of tail fat on recovery times in intact sheep and sheep with a ligated median sacral artery following similar anesthetic exposure with isoflurane was investigated. This study was performed using seven healthy fat-tailed Iranian Lori-Bakhtiyari ewe lambs. The lambs were anesthetized twice at two week intervals (the experiment was performed in two stages). After m...

the objective of this study was to estimate variance components and genetic parameters for growth curve parameters in shall sheep. studied traits were parameters of brody growth model which included a (asymptotic mature weight), b (initial animal weight) and k (maturation rate). the data set and pedigree information used in this study were obtained from the animal breeding center of iran and co...

Research on gene regulation has been made possible with the help of RNA sequencing applications such as RNA-Seq technology for high-throughput sequencing platforms. Recent studies have explored the transcriptomes from different tissues of domestic animals using RNA-Seq technology, but little research has been done to study the transcriptomes of breeds of sheep having different adipose tissue de...

this blinded, randomized experimental study was designed to evaluate the analgesic effects of adding epinephrine or xylazine to lidocaine solution for brachial plexus block (bpb) in sheep. nine healthy, fat-tailed female lambs (26.6 ± 1.5 kg) were randomly allocated into three groups: lidocaine 2%, 5 mg kg-1 (lid, n = 6), lidocaine (5 mg kg-1) with epinephrine 5 µg ml-1 (lidep, n = 6) or lidoca...

With climate change bound to affect food and feed production, emphasis will shift resilient adapted indigenous livestock sustain animal production. However, comprise several varieties, strains ecotypes whose genomes are poorly characterized. Here, we investigated genomic variation in an African thin-tailed Desert Sheep sampled Sudan, using 600K genotype data generated from 92 individuals repres...
