Genetics of susceptibility to bloat in cattle. I. An analysis of variation in degree of bloat in cows grazing red clover


, : Genetics of susceptibility to bloat in cattle. I. An analysis of variation in degree of bloat in cows grazing red clover. New Zealand Journal of Agricultural Research 19(2): 177-183

A herd of identical twin cows was graded for degree of bloat when grazing red clover pasture in the spring and autumn of 1972-73 and 1973-74. Sources of variation in the resulting bloat grades were analysed. Observer differences or interactions were very small. The main sources of variation were between grading times (30%) and between cows (20%). Afternoon gradings were, on average, higher than morning gradings.
