Influence of prepartum diet type on cow performance and subsequent calf performance
… utilized to evaluate the effects of prepartum diet type on cow and subsequent calf performance. Cows were blocked by BW and calving date into 16 pens and allotted to isocaloric, isonitrogenous dietary treatments: corn coproducts and ground cornstalks (COP) or ground hay (Hay). Treatment diets …

Longitudinal gene networks, canonical pathways and functional analysis of microarray data from Longissimus thoracis et lumborum muscle samples of early-weaned Angus steers
… +/- 10 d age at weaning) Angus steers (n = 7/diet) fed a high-starch (HiS, NEG = 5.98 MJ/kg diet dry matter) or low-starch (LoS, NEG = 4.97 MJ/kg) diet for 120 d, at which point all steers were switched to a common feedlot diet until slaughter. Muscle samples biopsies for transcript profiling …

Improving fiber by-product utilization in high concentrate diets
The effects of starch and fiber combinations in feedlot diets were examined to determine maximum whole shell corn (WSC) inclusion rate in high fiber diets and determine the effects of fibrolytic enzyme addition to WSC diets with increasing fiber inclusion. Soybean hull (SH) diets with increasing …

Ruminal degradation of protein and carbohydrate using a batch culture system, and response to roughage removal, rumen modifier inclusion and postruminal amino acid supply in feedlot cattle
… inclusion and postruminal amino acid supply in feedlot cattle. The objective of the first study was to characterize rumen N, starch, and NDF degradation rate (k[subscript d]), and further calculate ruminal degradable, undegradable and extent of digestion of those nutrients using a batch culture …

Enhancing the feeding value of corn crop residues to improve beef cattle production
Corn has been used in cattle diets for more the 50 years in the United States. However, since 2005 when the “Ethanol Era” started, the demand for corn to be converted in to ethanol has been increasing. The increased demand for corn to be converted into ethanol, led to increased corn prices. When …

Effects of dietary fat and protein from corn coproducts on growth, carcass characteristics, ruminal metabolism, and genomic regulation of marbling development in early-weaned beef cattle
… were conducted to evaluate the effects of dietary fat and protein from corn coproducts on growth, carcass characteristics, ruminal metabolism, methane production, and transcriptional regulation of marbling. In Exp. 1, crossbred heifers (n = 150) and steers (n = 100) were used to evaluate 1 …
