| HSP70-2 is well accepted as an indicator of heat stress. The purpose of this study was to investigate the physiological responses to heat stress of differential genotypes of HSP70-2 in dairy cattle. Thirty two female Holstein Friesian (HF) crossbred heifers, 2-3 years of age, 266 ± 5.6 kg body weight were placed outdoor with partial roof. Blood samples were collected to do genotyping of HSP70-2 using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. Ambient temperature, relative humidity and physiological responses, including rectal temperature, respiration rate, sweating rate, pulse rate, skin temperature, and N/L ratio were examined at 06.00, 14.00, 18.00 and 22.00. Genotyping revealed that there were 14 and 18... |

| Eight improved clones of forage-cane were evaluated for biomass yield performance under irrigatedcondition at Kasetsart University, Kamphaeng Saen campus, Nakhon Pathom during 2011-2012. The study wasdesigned with randomized complete blocks design with 4 replications in 3 crop-cycles, newly planted, first-ratoon and second ratoon that harvested at 6, 4 and 4 month after planting/ratooning, respectively. Total fresh biomass yield from 3 crop-cycles was 40.47 ton/rai. The total yield of 3 crop-cycles varied between 27.44 and 46.46 ton/rai. High biomass yield obtained from the new clones 28-2113, 28-2114 and 28-1727 that were equal to 46.46, 44.86 and 42.96 ton/rai, respectively. Although, three new forage-cane clones had high potential of biomass yield.... |

| 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... |
