Physiological Limitations to Using Concentrates to Increase the Digestible Energy Intake of Ruminants given Roughage Based Diets
The low intake and digestibility of low-quality roughages such as mature forages or crop residues often results in a digestible energy intake insufficient for a desired level of production. One alternative to increase digestible energy intake is to provide supplementary concentrates of high digestibility. ‘ Associative effects on forage fibre digestion may occur when roughage and concentrate ar...
متن کاملSteam-rolled wheat diets for finishing cattle: effects of dietary roughage and feed intake on finishing steer performance and ruminal metabolism.
Two experiments were conducted to determine the influence of dietary roughage concentration and feed intake on finishing steer performance and ruminal metabolism. In Exp. 1, 126 steers (334 kg) were used in a completely randomized design and fed (120 d) diets of steam-rolled wheat without roughage or containing 5, 10 or 15% roughage (50% alfalfa hay:50% corn silage). Steers fed 5 or 10% roughag...
متن کاملThe effect of water availability on feed intake and digestion in sheep.
Six castrated male Karagouniko sheep, offered three levels of water, were used in a 3x3 Latin Square design to study the effects of mild water restriction on roughage intake and digestion. The three treatments were offered water ad libitum throughout the day (A), made available to the animals for 1h daily (B) or 65% of the water consumed ad libitum (C). Sheep in Treatment A consumed more water ...
متن کاملThe influence of roughage intake on the occurrence of oral disturbances in captive giraffids
Feeding behaviour of giraffe and okapi in captivity can differ significantly from the state in the wild. Duration and complexity of feeding and ruminating behaviour, and total amount of food ingested, are o�en reduced, while the energy content of the diet is increased compared to the wild. As known from domestic ca�le in intensive keeping systems, oral disturbances like tongue-playing or lickin...
متن کاملEffects of calcium magnesium carbonate and roughage level on feedlot performance, ruminal metabolism, and site and extent of digestion in steers fed high-grain diets.
A feedlot growth performance experiment and 2 metabolism experiments were conducted to evaluate dietary roughage concentration and calcium magnesium carbonate in steers fed a high-grain diet. In Exp. 1, one hundred ninety-two crossbred yearling steers (320 +/- 10 kg of initial BW) were fed diets based on steam-flaked corn with 0, 0.75, or 1.5% CaMg(CO(3))(2). There were no effects (P > or = 0.1...
