| Abstract: | Six Holstein bulls and their 40 mated cows and 40 daughters were selected in this experiment.Cattle blood was sampled both in heat stress and nonheat stress period.The heredity of the potassiumcontent in erythrocytes was determined,and its heredity reliability as a heat tolerant index was examined byother assessing indexes.The potassium content showed a heredity to some extent.Estimates of heritabilitywere 0.248 and 0.387 with regard to the father and mother respectively.Both parents'cooperative heredityis more significant than single parent's.Heredity reliability and significance of the potassium content inerytyrocytes as a selecting index of dairy cattle's heat tolerance were discussed,and theoretical evidence forbreeding heat tolerant strains in Holstein carrles was provided. |
