TL;DR: Results indicate that DHA-G can be successfully included in the diets of growing lambs, up to 3% DM, with the potential to improve carcass characteristics and the FA profile of adipose tissue and muscle.

TL;DR: Antimicrobial administration was not found to be essential for the maintenance of inherently ampicillin-resistant and tetracycline-resistant (Tetr) E. coli in control animals; however, higher TetrE.

TL;DR: Examination of carcass and meat quality traits of cattle fed diets containing corn or wheat (20% or 40%) DDGS (DM basis) as compared to a standard barley-based finishing diet (control) found that feeding wheat DDGS had no negative effects, and feeding cornDDGS had some positive effects on meat quality characteristics of beef.

TL;DR: Evaluated feed intake, ADG, carcass quality, eating behavior, and blood metabolites in feedlot beef steers fed diets that varied in proportion of wheat dried distillers grains with solubles (DDGS) indicate that wheat DDGS can be used effectively in feedLot diets, decreasing the need for barley grain or silage without negatively affecting growth performance and carcass characteristics.

TL;DR: Southern Alberta, which has a cold climate dominated by strong chinook winds, has the highest density of feedlot cattle in Canada, and runoff from beef cattle feedlots in this unique region has not been investigated, and curve numbers between 52 and 96 were required to match the USDA Natural Resources Conservation Service predicted runoff and actual runoff volumes.
