A 4-year-old Holstein dairy cow in peak lactation is losing body weight at a faster rate than desired. The farmer has asked for your help in rebalancing the cow's ration. The cow needs a ration that provides 2.65 Mcal/kg of metabolizable energy. The feed will be provided as a total mixed ration (TMR) with the forage/roughage mixed with the concentrate, and at least 50% of the TMR needs to be forage/roughage for rumen health.

Sorghum silage O f. Corn silage Which concentrate would you recommend for the new ration? O a. Soybean meal O b. Cotton seeds O c. Dried distillers grains with solubles O d. Corn and cob meal O O f.
