the families of tgf-β proteins are the most important growth factors in the ovary for growth and differentiation of early ovarian follicles. three related oocyte-derived members of the transforming growth factor-β superfamily namely growth differentiation factor 9 (gdf9), bmp15 and bmpr-ib have been shown to be essential for follicular growth and ovulation. different mutations in the gdf9 gene ...

More than 20.1 million hectares of the territory Republic Uzbekistan are pastures, which 16-17 located in desert region. Karakol sheep, unlike other farm animals, have very valuable biological properties, they able to breed harsh continental climates, sparsely vegetated, saline, arid without consuming absolutely green fodder summer, autumn and winter has ability provide products (astrakhan leat...

Sheep farming has been an important sector of the UK’s economy and rural life for many centuries. It is favored source wool, meat milk products. In era exponential progress in genomic technologies, we can now address questions what special about UK sheep breed genotypes how they differ genetically form one another from other countries. We reflect their natural history determined at level geneti...

Abstract Background Goats, often associated with sheep, are a vital part of the national economy in many countries around world, and goat farming contributes significantly to family economy, sustainable livelihoods poverty reduction. In order study system Algeria, this study, which started between September 2012 June 2015, involved 141 farms 104 villages 21 wilayas Algeria. Results The results ...

The objectives of this study were to 1) evaluate the genetic diversity of Navajo-Churro sheep using pedigree information; 2) examine the distribution of the Navajo-Churro population; and 3) evaluate the effect of breeder dynamics on genetic conservation of the breed. Pedigree data and breeder information (city and state) were obtained from the Navajo-Churro Sheep Breed Association. Inbreeding c...

This study presents a dynamic characterization of the sheep milk transcriptome aiming at achieving a better understanding of the sheep lactating mammary gland. Transcriptome sequencing (RNA-seq) was performed on total RNA extracted from milk somatic cells from ewes on days 10, 50, 120 and 150 after lambing. The experiment was performed in Spanish Churra and Assaf breeds, which differ in their m...

The complete genome sequence of a beak and feather disease virus (BFDV) encoding two major open reading frames (ORFs) was characterized in a wild Moluccan red lory (Eos bornea). This is the first report of a BFDV genome from Indonesia and the first reported BFDV infection for this host species.

We report the occurrence of lung cancer in a six months old lamb of Ouled Djellal breed from Algeria. The main clinical sign was a considerable amount of whitish foamy fluid discharge from the nostrils when the animal head was lowered and the rear end was lifted. The post-mortem examination revealed the presence of enlarged, heavy and edematous lungs with diffuse or foci areas, reddish or white...

the genotypes for beta-lactoglobulin (blg) and calpastatin (cast) were determined by polymerase chain reaction (pcr) and restriction enzyme digestion and genotyped for calpain (capn) by pcr-sscp method in a native iranian breed sheep, kordi. blood samples were collected from 100 pure bred kordi sheep from kordi breeding station located in shirvan, mashhad. the extraction of genomic dna was base...
