Numerous options are available to assist in the management of trace mineral nutrition of grazing cattle. In recent years, significant research efforts have bee...
متن کاملSupplementation of Concentrate with Different Levels of Protein on Nutrient Intake, Digestibility and Growth of Red Chittagong Heifers
The study was undertaken to investigate the effects of concentrate supplementation with different protein levels on intake, digestibility and growth performance of Red Chittagong (RC) heifers fed urea molasses straw (UMS) based diet. Twelve RC heifers having average live weight of 124.83±43.15 kg and aged between 8 to 14 months were selected for 90 days feeding trial. Animals were divided into ...
متن کاملEscape protein supplementation of yearling steers grazing smooth brome pastures.
Two grazing trials utilizing individually supplemented yearling steers were conducted to study the effect of supplemental escape protein on steer performance during the active growth periods, spring and fall, of smooth brome (Bromus inermis). Graded levels (0, .11, .23 and .34 kg.head-1.d-1) of an equal-protein-basis mixture of bloodmeal and corn gluten meal were offered daily, replacing corn s...
