Sites, rates, and limits of starch digestion and glucose metabolism in growing cattle.
TLDR
The main limit to use of dietary starch to support live weight gain is digestion and absorption from the small intestine, and increased oxidation of glucose at greater starch intakes may alter energetic efficiency by sparing other oxidizable substrates, like amino acids.
Effect of level and type of fat on subacute acidosis in cattle fed dry-rolled corn finishing diets.
TLDR
Five experiments were conducted to determine the effect of fat addition to dry-rolled corn finishing diets on subacute acidosis and area below pH 6 was determined to quantify the total decrease in ruminal pH over a 24-h period.
Effect of bovine respiratory disease during preconditioning on subsequent feedlot performance, carcass characteristics, and beef attributes.
TLDR
Segregating animals with multiple BRD treatments and feeding them to an acceptable carcass endpoint may be a viable strategy for increasing value of animals treated for BRD.
Rumen temperature change monitored with remote rumen temperature boluses after challenges with bovine viral diarrhea virus and Mannheimia haemolytica.
TLDR
Rumen temperature boluses appear to have potential as a tool for detecting temperature changes associated with adverse health events such as exposure to bovine respiratory disease and BVDV.
Influence of soybean hull supplementation on rumen fermentation and digestibility in steers consuming freshly clipped, endophyte-infected tall fescue.
TLDR
Six steers fitted with rumen and duodenal cannulas were used in a crossover design to evaluate intake, rumen fermentation, and site of nutrient digestion of freshly clipped, endophyte-infected E+ tall fescue with or without soybean hull (SH) supplementation at 0.60% of BW (OM basis).
Growth and Development Symposium: Impacts of inflammation on cattle growth and carcass merit.
TLDR
The objective of this paper is to review data to help explain the economical and physiological effects of inflammation on cattle growth and carcass merit.
Pancreatic exocrine secretion in steers infused postruminally with casein and cornstarch.
TLDR
Abomasal infusion of protein with starch stimulated a greater pancreatic secretion of alpha-amylase activity into the intestine than infusion of starch alone, and postruminal protein infusion on pancreatic exocrine secretions was evaluated.
