Goat research in the United States has increased but at a rate less than that in production. Research on goat meat includes nutritional quality, packaging, color, sensory characteristics, and preslaughter management. Goat skins have value for leather, but quality of goat leather has not been extensively studied. Research in the production, quality, antibiotic residues, and sensory characteristi...

Cashmere is only produced from Maraz (Kurdi) goat breed in Iraqi Kurdistan Region. The objective of this study was to assess the genetic diversity of different Maraz color types, black goat and Shami breeds using random amplified polymorphic DNA (RAPD) markers. Fourteen primers were used and nine out of them were selected based on their number of bands (NB) and polymorphic characteristics. Thes...

p70 ribosomal S6 kinase (p70S6K) can integrate nutrient and growth factor signals to promote cell growth and survival. We report our molecular characterization of the complementary DNA (cDNA) that encodes the goat p70S6K gene 40S ribosomal S6 kinase 1 (S6K1) (GenBank accession GU144017) and its 3' noncoding sequence in Inner Mongolia Cashmere goats (Capra hircus). Goat S6K1 cDNA was 2,272 bp an...

Fiber diameter, a quantitative trait, is controlled by minor effect polygenes. Keratin-associated proteins (KRTAPs) are an important part of hair, and their rich polymorphisms facilitate the mining cashmere trait molecular markers. In this study, Jiangnan Tibetan goats were taken as research object; multiplex PCR exome sequencing technology used to identify exon regional KRTAP15-1, KRTAP13.1, K...

One hundred eighty (180) skin samples were taken from the mid-right side of 30 Raieni Cashmere goat male and female kids at 1 mo, 1.5 mo, 2 mo, 2.5 mo, 3 mo and 3.5 mo of age. Numbers of primary and secondary skin follicles were determined for each sample. Numbers of secondary follicles increased until 3 mo of age, but numbers of primary follicles did not change after birth of the kids. The ski...

Cashmere goat skin contains two types of hair follicles (HF): primary hair follicles (PHF) and secondary hair follicles (SHF). Although multiple genetic determinants associated with HF formation have been identified, the molecules that determine the independent morphogenesis of HF in cashmere goats remain elusive. The growth and development of SHF directly influence the quantity and quality of ...

Previous molecular genetic studies of the goat hair life cycle have focused primarily on a limited number of genes and proteins. To identify additional genes that may play important roles in hair follicle cycle regulation, Illumina sequencing technology was used to catalog differential gene expression profiles in the hair growth cycle (anagen to catagen) of goat, comparing the primary hair foll...
