The effect of cereal grain type on production performance and Clostridium perfringens colonization in cattle
MetadataShow full item record
Three experiments were conducted to investigate the effects of various cereal grain types on the production performance of dairy cattle and the colonization of Clostridium perfringens in the intestinal tract of cattle. The first experiment investigated the effect of feeding two different cultivars of barley (cv. Harrington and Valier) and two different cultivars oat (cv. Derby and AC Assiniboia) grain on feed intake, milk yield and milk constituents. It was found that barley or oat may both be successfully incorporated into the concentrate portion of western Canadian dairy rations. NRC Dairy 2001 predictions for both oat and barley diets very closely predicted dry matter intake and milk production. AC Assiniboia oat fed cows produced the lowest percentage of fat (P
