Carbohydrate utilization in the pre-ruminant calf.
3. Maltose and fructose utilization was low in young calves and increased slightly with age. 4. Sucrose and starch were not utilized. 5. Studies with three older pre-ruminant calves (aged 53, 88 and 106 days) in which the carbohydrates were infused into the proximal duodenum showed that glucose, galactose, lactose and xylose all caused marked increases in the level of blood reducing sugar, wher...
متن کاملThe effect of environmental temperature on the performance and health of the pre-ruminant and ruminant calf.

متن کاملRuminant Nutrition: Nitrogen Sources and Utilization
The objective of this study was to evaluate the effects of replacing protein sources that are commonly used in North America with triticale dried distillers grains with solubles (TDDGS) as a source of dietary N on the productivity of lactating dairy cows. Experimental diets contained 17.1% TDDGS, 17.5% Corn DDGS (CDDGS), 13.1% canola meal (CM), or 10.2% soybean meal (SBM) on a DM basis so that ...
