| Outline of Final Research Achievements |
(1) Play behavior in Japanese Black calves gradually declines as they mature and that it may be controlled by variations in the MAOA gene. (2) Facial hair whorl location may be effective to predict temperament in cattle, but that there are some temperaments to change under the influence of environment and/or handlings. (3) By analyzing the association between the polymorphisms and temperament scores of behavioral tests, significant effects of CRH polymorphism and interaction were not detected but cattle with wild homo-type of LEP tended to permit the contact of stranger when feeding (4) SNPs (calpastin, Leptin and acylCoA- diacylglycerol-acyltransferase) affect temperament in Japanese Black cattle. (5) Thermotolerance scores, cattle without the wild-type allele of UCP and NPY showed low scores of thermotolerance and disease resistance.
