reported here are a mix of real (albeit sometime outdated) and ad hoc generated information, but while the numerical results might be unrealistic (and surely oversimplified since there are several other factors and costs that we do not take into consideration) when compared to actual market situation, the basic approach remains valid. We can assume (for the purpose of this exercise) that feeding a cow is a problem of supplying the necessary nutrients with a mix of what is called roughage and concentrates (this is called a Feeding Ration ): 1. Roughage – Feeds that generally are high in fiber and include: Alfalfa, Clover, Soybean and Silage; 2. Concentrate – Feeds that generally are high in energy and low in fiber. They include: Corn, Cottonseed, Barley and Oats.

- 2 - Each of the feeds above is characterized by the concentration of: a. Dry Matter (DM) – what remains after all of the water is evaporated out of a feed. Livestock need to consume a certain amount of dry matter per day (measured in lbs. or kg/day) to maintain health and production. It is related to the total nutrient content of a feed. b. Proteins – organic compounds that contain carbon, hydrogen, oxygen, and nitrogen ( ± iron, phosphorus, and sulfur). They are needed to grow new tissues and to repair old tissues in an animal. c. Carbohydrates (Carbs) – major macronutrient that is one of the main source of energy for animals. d. Fats – major macronutrient that is one of the main source of energy for animals It has also been recognized that in an animal body, proteins serve special growth functions that cannot be performed by the other nutrients (which are more important for fattening), so there’s the need to express the value of a feeding ration as a function of the protein content vs the other major nutrients. This is accomplished using the Nutritive Ratio (N.R.): ࠵?. ࠵? = ࠵?࠵?࠵?࠵?࠵? + (࠵?࠵?࠵? ∗ 2.25) ࠵?࠵?࠵?࠵?࠵?࠵?࠵?࠵? Problem 1 : Formulate a daily Feeding Ration for a lactating cow of 1,000 lb., so that it will have enough energy to produce 22 lb. of milk daily. [ You will need to set up your calculations in the Excel ä file downloaded from the module and save them. The Excel ä file will have to be then uploaded in the class site for this assignment 1 ] a. Identify the nutritional needs for the cow (Table 1) 2 ; b.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
