Silage and alfalfa for dairy cows and their values as compared to other crops, pp. 91-96 PDF (1.2 MB)
94 Fortieth Annual Report of the The question may be asked: Will cows do well if fed the entire year upon silage and alfalfa? To this it may be said that in ex- periments carried on by the Illinois Experiment Station cows fed en- tirely upon silage and alfalfa for a year were at the end of that itme in good physical condition and produced creditable yields of mila Cow No. 1 produced 8,735 lbs. of milk containing 351 lbs. of fat; she consumed 14,880 lbs. of silage and 1,672 lbs. of green crops and 6,396 lbs. of alfalfa. In other words for each 100 lbs. of milk produced, she consumed 170 lbs. corn silage, 19 lbs. of green crops and 73 lbs. alfalfa hay. Cow No. 2 produced in one year 7,434 lbs. of milk con- taining 259 lbs. of fat. She ate 14,862 lbs. of silage, 1,612 lbs. green crops and 5,588 lbs. of alfalfa hay. In comparing the relative value of timothy hay and alfalfa it was found that when milk was worth $1.30 per hundred and timothy hay valued at $10.00 per ton, that alfalfa was worth $20.86 per ton and gave a return per acre of $68.44 more than an acre of timothy. In briefly summing up this subject, I can say: First: There are no crops grown upon the farm more important to the dairy farmer than alfalfa and corn. Second: Alfalfa will produce more digestible nutrients per acre than any other agricultural crop. A yield of 4 tons of alfalfa hay per acre produces 4,000 lbs. of digestible nutrients, 880 lbs. of which are digestible protein. Third: Corn comes next to alfalfa in the production of nutrients for the cow. An acre yielding ten tons of green corn will produce 3,440 lbs. of digestible nutrients, 280 lbs. of which are digestible pro- tein. Fourth: No crops .compliment each other better for feeding the dairy cow than silage and alfalfa. The silage furnishes succulence for the cow and a large amount of heat producing elements. Alfalfa provides the dry roughage; is rich in the element protein and mineral, matter which are so important to the growing of animals and to cows producing milk. In short: Alfalfa and silage have a productive feeding value that cannot be excelled by any other combination of roughage grown on the farm. Fifth: When alfalfa is used properly in a rotation, it is beneficial to the soil but it is a mistaken idea to think that the alfalfa plant enriches the soil. It must be fed to live stock on the farm if the greatest value is to be obtained as a soil improver.
