This was all of information i was given.. i need help with step 7 which is all of fourth picture

AnSc 318 Problem Set Il-Equine Ration Balancing Equine Ration Balancing 1. Horses are typically fed forages and grain concentrate mixes separately (unlike total mixed rations used in feeding finishing cattle or dairy cows). If horses are fed in confinement, they should be given a minimum of 1 kg of a forage per 100 kg body weight (1% BW). Estimated feed consumptions are given in table 5-4 (see attached) for various borse classes. A grain concentrate mix is provided if the forage is unable to supply all required nutrients. In formulating a grain concentrate mix for a horse, one must consider: (1) the total nutrient requirements of the horse and (2) the nutritional contributions of the forage. 2. A portion of the new NRC (1989) requirements for horses is attached to this problem set. In balancing horse rations, use the attached tables or the computer program "Equine" to determine nutrient requirements. An example output from "Equine" is attached, Digestible energy is used to balance borse rations for energy. The following equations derived from NRC (1989) are used to estimate DE requirements (Mcal/day) in borses. a. De maintenance: DEm = 1.4 +.03.BW where: BW = body weight, kg b. Stallions (breeding season): DE = 1.25 [DEm c. Pregnant mate: 9 mo-> DE = 1.11. [DE] 10 mo-> DE = 1.13. (DEm] 11 mo-> DE = 1.20. (DE) d.

We will balance rations for horses on an as-fed basis. Make sure to record the as-fed nutritional content of feeds. When having a forage analyzed for use in horse diets it is important to realize that the TDN values typically given are for cattle. The TDN value of a low- to medium quality forage will be lower for horses than for cattle. Use the following equation to estimate the TDN value of a low-or medium quality forage for horses: TDN (horse] = TDN [cattle) 8 To convert TDN to DE: DE [Mcal/kg) = [%TDN + 100). 44 89 Problem Set #11--Equine Ration Balancing Problem Exercise 1: Formulate a ration for a 400 kg mature horse performing at a moderate work level. Use coastal bermuda grass hay, soybean meal, limestone, dicalcium phosphate and a 2:1 grain mix of corn and oats. For purposes of this lab and the homework on balancing horse rations assume that a trace mineral/vitamin premix will be added to the diet to meet all of the horse's trace mineral and vitamin needs.
