Optimun Levels Of Dietary Crude Protein And Monensin For Steer Calves On Limit-Fed, High Concentrate Diets, M.L. Sip, R.H. Pritchard, M.A. Robbins
South Dakota Beef Report, 1987
One hundred ninety-two Angus and Angus x Limousin calves (611 lb) were randomly allotted to one of four Levels of crude protein intake and three dosages of monensin in an 80% concentrate diet. Intake of the complete diet was restricted to allow 2.2 lb average daily gain over an 86-day period. Crude protein was fed at 90, 100, 110 or 120% of the gram daily requirement described by NRC. Monensin was fed at 120, 180 or 240 mg/head/day. Each 10% increase in dietary crude protein caused a .13 lb increase in ADG, a .34 unit improvement in feed efficiency and …

Limit-Fed, High Energy Diets For Growing Cattle, J.J. Wagner, T.L. Mader
South Dakota Beef Report, 1987
Limit-fed, high energy (57 Mcal per cwt dry matter) diets were compared to full - fed, Low energy (46 Mcal per cwt dry matter) corn silage and alfalfa hay diets. Feed conversions were 5.68 and 5.78 lb of dry matter per lb of gain for the limit-fed silage and alfalfa diets vs 6.86 and 7.45 lb of dry matter per lb o f gain for the full - fed silage and alfalfa hay diets, respectively. Break-even roughage prices were calculated from feed efficiency and ration cost information. If corn is valued to the bunk at 31.50 per bushel and soybean …
