| 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... |

| The sixty-two of the exotic germplasms waxy corn were performed. The agronomic characters were averaged 45 - 52 days to flowerings, opaque and small kernel. Almost all plant aspects were green and less uniformity, unfortunately, downy mildew was susceptible. Three methods for S1 selection were (1) half - sib (HS) (2) full - sib (FS) and (3) S1 (S1) progeny test. Each method was received for two ears. Also, the agronomic characters were recorded, 45 - 52 days to tasseling and 46 - 52 days to silking. Economic yields, green and white weight were 588 - 1,063 and 340 - 631 kg/rai, namely, UPDW-0013 was showed the best of both. Furthermore, UPCW-0004 showed that the best shelling (71.16%). And, cutting trait was UPWC-0002 (66.67%). Afterward, 26 lines are... |
