Thirty-six Spanish goat wethers (196 12.9 days of age and 17.5 4.60 kg BW at experiment initiation) from a herd previously selected for cashmere growth were used to determine effects and interactions of ad libitum consumption of diets differing in concentrations of CP (10% and 15%) and ME (2.00, 2.35 and 2.70 Mcal/kg; DM basis) on growth and cashmere ®ber production in an 84-day, fall-season ex...

Growth hormone (GH) has an effect on a broad variety of physiological parameters such as lactation, reproduction, growth and metabolism. Thus, the aim of this study was to detect GH gene polymorphism and its association with breeding values of production and reproduction traits in Raini Cashmere goat. Breeding values were estimated using records on 26731 Raini Cashmere goats. To study GH gene p...

The insulin-like growth factor-binding protein-5 (IGFBP-5) is one of the 6 members of the IGFBP family and is involved in the regulation of cell growth, apoptosis, and other IGF-stimulated signaling pathways. To determine the significance of IGFBP-5 in the Inner Mongolia Cashmere goat (Capra hircus), a hair follicle-specific expression vector of IGFBP-5, pCDsRed2-K-IGFBP5 (6.7 kb), was construc...

the effect of melatonin and bromocryptine on body weight, fibre shedding and cashmere traits was investigated by using 24 raeini female goats (2-3 years old) in four experimental groups: control (c); melatonin (mi) implant (18 mg at first and repeated after 40 days), bromocryptine (b) injection, (0.5 mg/kg bw per three days) melatonin and bromocryptine implant and injection (mib). all goats wer...

BACKGROUND MicroRNAs (miRNAs) are small noncoding RNA molecules that serve as important post-transcriptional gene expression regulators by targeting messenger RNAs for post-transcriptional endonucleolytic cleavage or translational inhibition. miRNAs play important roles in many biological processes. Extensive high-throughput sequencing studies of miRNAs have been performed in several animal mod...

Cashmere goat (Capra hircus) hair follicle development and cycling can be divided into three stages: anagen, catagen and telogen. To elucidate the genes involved in hair follicle development and cycling in cashmere goats, transcriptome profiling of skin was carried out by analysing samples from three hair follicle developmental stages using RNA-Seq. The RNA-Seq analysis generated 8487344, 81425...

As a member of the POU-domain family, the POU1F1 is a positive regulator for growth hormone, prolactin and thyroid-stimulating hormone b, by binding to target DNA promoters as a dimer in mammals. This study described the polymorphisms at the goat POU1F1-DdeI locus and analyzed the distribution of alleles in 15 indigenous Chinese goat breeds. The PCR-RFLP analysis showed a predominance of the D1...

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...
