exam 1 cow-calf 1 Nutritionists recommend dividing the beef cow's annual production cycle into periods corresponding with the cow's nutrient needs. Divide a cow's annual production cycle into reasonable periods and describe the cow's nutrient requirements during each period. Suggest a few feeds that would be appropriate for each period. Explain the relationship between the cow's body condition score and pregnancy rate. How does cow size and level of milk production affect profitability of cow-calf operations? Make a list of management tools available to cattle producers to change the cows nutrient requirements to match the nutrients supplied by their forage. Explain in detail for 3 of these tools how they could be used in a particular setting to increase profitability. What is the most useful tool available to cattle producers to assess the adequacy of their nutritional program? Why is it the most useful tool and how is it best applied
