Effects Of Level Of Concentrate And Forage Availability On The Performance Of Beef Cows Grazing Winter Range, M. C. Namminga, R. J. Pruitt, C. A. Tusler, P. S. Johnson
South Dakota Beef Report, 1991
A winter grazing study was conducted using 120 pregnant Simmental x Angus cows to determine the effect of level of concentrate supplement and amount of available forage on cow performance. Concentrate supplements were fed at a high, medium and low level which included corn, corn-soybean meal and soybean meal, respectively, and were formulated to provide .7 Ib of crude protein per cow daily. Two winter pastures with distinctly different amounts of available forage were used in the trial. The amount of available forage had a greater effect on body weight and condition score change than did level of concentrate supplement …
Methionine Addition To A Urea-Grain Supplement For Cows Grazing Dormant Winter Range, P. A. Momont, R. J. Pruitt, P. S. Johnson
Methionine Addition To A Urea-Grain Supplement For Cows Grazing Dormant Winter Range, P. A. Momont, R. J. Pruitt, P. S. Johnson
South Dakota Beef Report, 1991
A 2-year grazing study involving 103 mature pregnant Simmental x Angus cows grazing dormant winter range was conducted to determine the effects of methionine addition to a urea-grain supplement on forage intake and digestibility and on cow performance. Four protein supplements designed to supply .8 1b crude protein per head daily were fed from mid-November to mid-February. Supplements contained (1) urea (CON), (2) urea plus methionine (MET), (3) urea plus sodium sulfate (SUL) and (4) soybean meal (SBM). Twice during the second winter (late November and late January), cows were administered controlled release chromic oxide boluses and fecal samples were …
