Changes in cow-calf operations and management need to be deliberate and focus on consumer preferences that are substantive and enduring. For the sake of argument these preference changes could include: 1) continued erosion of the image of the cattle

The mature size (MS) of cows in the United States is diverse, which leads to diversity in the MS of feeder cattle and hot carcass weights (HCW) of fed cattle. Cattle feeders must manage this inherent variation. Given that implants alter MS, they may

The objective of this experiment was to determine the effects of cow energy status during mid-gestation on progeny growth performance and health. To alter maternal energy status, cows (n = 151) were either fed to achieve or maintain BCS 5.0 to 5.5 (p

Heat stress (HS) can be a significant source of risk for Midwestern cattle feeders. Feedlot managers (n = 46) from South Dakota, Minnesota, and Nebraska were surveyed regarding facilities, HS mitigation strategies, perceived success or failure, and s

Research has suggested that maternal undernutrition may cause the development of a thrifty phenotype in the offspring, potentially resulting in greater adiposity and reduced muscle mass. These alterations in adipose and muscle development could have

Subcutaneous fat and marbling both increase in beef cattle during the feeding phase but are antagonistic in regard to their contribution to beef carcass value. The objective of this study was to determine whether cellular factors associated with marb

Crossbred beef heifers [n = 96; initial shrunk BW=238 kg (SD 21.5)] were used in a completely randomized design to evaluate climatic effects on feedlot heifer growth and efficiency. The study was conducted from November 8, 1991 to May 11, 1992. Heife

The objective of this study was to determine if maternal energy status during mid-gestation influences the expression of genes regulating muscle and fat development, and muscle characteristics that may impact meat tenderness. Cows grazed dormant, nat

Angus and Angus x Limousin cross steers (n = 182; initial BW = 309 +/- 27.8 kg) were used to evaluate the influence of an estradiol-trenbolone acetate implant (containing 24 mg of estradiol and 125 mg of trenbolone acetate) on production efficiency a

Angus steers of known age (265 +/- 17 d) and parentage were used in a 2-yr study (yr 1, n = 40; yr 2, n = 45) to evaluate the relationship between percentage of i.m. fat content of the longissimus dorsi at the 12th rib and carcass characteristics dur
