This study attempted to clarify the appearance of 70 kDa heat shock protein (HSP70) in spermatozoa and its relationship with the semen quality in crossbred Holstein Friesian (HF) bulls. Semen from 10 HF bulls was collected 8 weeks during rainy (THI = 79.06), winter (THI = 74.30), and summer (THI = 80.05). Semen quality was evaluated in terms of semen volume, sperm concentration, sperm motility, sperm viability, and percentage of abnormal spermatozoa. It was found that mass movement of sperm in the summer and rainy seasons were significantly lower than in the winter (P<0.01). The percentage of abnormal sperm were significantly lowest in the summer (P<0.01). The western blot analysis of the levels of HSP70 in spermatozoa found that it was significantly... |

Objective of this study was to detect the SNPs of GHSR, IGFI, cGH and IGFBP2 genes and their association with growth traits (body weight at 0, 4, 8, 12 and 16 weeks of age, ADG during 0-4, 0-8, 0-12 and 0-16 weeks of growth) and carcass trait (breast width) of Thai native chickens (Chee and Pradu Hang Dam). Blood samples were randomly collected from 60 chickens/breed. The genotypes were detected using PCR-RFLP methods with specific primers for each gene. A mixed model was used to analyze the associations of candidate genes with growth traits. In Chee, the GHSR gene was not significantly associated with growth traits, while, the IGFI gene was significantly associated with body weight at 12 and 16 weeks of age and ADG during 0-12 and 0-16 weeks of age. The... |
