Small intestinal fermentation contributes substantially to starch disappearance in milk-fed calves of starch (66%) was lower than that of glucose (85%) when infused in the abomasum of steers (Kreikemeier and Harmon, 1995), indicating that enzyme activity required for the hydrolysis of starch to glucose limits starch digestion. Which enzyme system is limiting starch digestion in milk-fed calves i

Nutrient digestion by dairy cows fed diets replacing starch with non- forage fiberimpacts on lactating dairy cows, such as ruminal acidosis and laminitis along with higher feed costs and lower income from reduced milk components. Dried distillers grains with solubles (DG), a co-product of the ethanol industry, is an excellent source of energy. Ranathunga . (2010) demonstrated tha

Effect of different dietary levels of Quebracho tannin extract on nitrogen and fiber digestibility asidered to increase rumen-escape protein, higher CT intakes may inhibit microbial crude protein (MCP) synthesis and decrease nutrient digestibility (Barry and McNabb, 1999). Our aim was thus to determine how graded dosages of a Quebracho tannin extract (QTE; 75% total phenolic content) influence MCP

Performance, efficiency and estimated maintenance energy requirements of , and , cattleny difference between breed types (Tedeschi .., 2002). A recent focus on genetic selection for increased feed efficiency has led to greater efforts to quantify individual feed intakes on farms and research institutes. This study has combined several of those data sets, including . and . cattle, in h
