Please help! I am so lost

Formulate a ration for each of the following scenarios. Your final answer should be expressed in kilograms, on both a DM and As-Fed basis. Lastly show that your final ration meets DE, CP, Ca, Cu and vitamin E requirements. 1. Your horse has requirements for gestation month 3 (See Table 2). The available feeds are hay #1 and grain-mix-concentrate (See Table 1). Use the following questions to guide you through the problem. 1.1) How many Mcals of DE will the horse consume if it eats its entire DM intake in hay #1? Mcals of DE 1.2) Does the above DE intake meet or exceed the DE requirement for a 500 kg horse with requirements for the third month of gestation? If yes, skip to line 1.5 below. If not what is the deficiency? Mcals of DE deficient 1.3) Calculate the advantage for hay #1 and the grain-mix-concentrate. Advantage, Mcals 1.4) Calculate the amount of grain-mix-concentrate and hay #1 on both a DM and as-fed basis. Skip to line 1.6 next. 1.4) Calculate the amount of grain-mix-concentrate and hay #1 on both a DM and as-fed basis. Skip to line 1.6 next. Grain-mix-concentrate: kg DM kg as-fed Hay: kg DM kg as-fed 1.5) How much of the hay must the mare consume to exactly meet her DE requirement (amount of hay required to meet DE = Mcals DE required divided by Mcals DE per kg DM hay). kg DM kg as-fed 1.6) Given the amounts of hay and grain calculated above in line 1.4 or the amount of hay in line 1.5, are the protein, mineral and vitamin requirements met? (amount of feed x concentration of nutrient in the feed = amount of nutrient consumed; is this amount greater than or equal to the requirement listed in Table 2?) Nutrient consumed Nutrient Required Difference CP Ca Cu Vit. E 1.7) If any of the nutrient consumed above is less than the nutrient required, how much mineral-vitamin supplement should be fed. (Deficiency divided by nutrient concentration of the supplement = amount of supplement to be fed) 1.8) List the amounts of hay + mineral-vitamin supplement or hay + grain to be fed in the final ration.
