Evaluation of First Treatment Timing, Fatal Disease Onset, and Days from First Treatment to Death Associated with Bovine Respiratory Disease in Feedlot Cattle.

Bovine respiratory disease (BRD) is a frequent beef cattle syndrome. Improved understanding of the timing of BRD events, including subsequent deleterious outcomes, promotes efficient resource allocation. This study's objective was to determine differences in timing distributions of initial BRD treatments (Tx1), days to death after initial treatment (DTD), and days after arrival to fatal disease onset (FDO).

Effects of early or conventional weaning on beef cow and calf performance in pasture or drylot environments.

Performance of cows and calves during 63-d early or conventional weaning periods was evaluated. Spring-calving beef cows ( = 167) of similar age, body condition score (BCS), and body weight (BW = 599 ± 54.5 kg), and their calves (initial BW = 204 ± 26.

Effects of weaning method on postweaning performance by early weaned beef calves.

Health and performance of early-weaned steers were evaluated during a 56-d weaning period, a 56-d feedlot receiving period, and a 165-d feedlot finishing period. Steers ( = 239; 128 ± 14 d of age) were assigned to a 56-d weaning treatment: drylot weaning (D) or pasture weaning (P). Pasture steers grazed mature, native tallgrass range (89.

Feeding and Watering Beef Cattle During Disasters.

Animal care, feeding, and nutrition in the wake of a natural disaster or emergency situation are difficult and require resourcefulness. Immediately following the event, the most basic needs essential for survival of cattle (ie, water, feed, rest, and recovery) should be addressed. Once these basic needs have been addressed, the primary objective then becomes to maintain the present condition of the animals to reduce the potential for negative production outcomes.

Post-ruminal branched-chain amino acid supplementation and intravenous lipopolysaccharide infusion alter blood metabolites, rumen fermentation, and nitrogen balance of beef steers.

Steers exposed to an endotoxin may require additional branched-chain AA (BCAA) to support an increase in synthesis of immune proteins. This study evaluated effects of bacterial lipopolysaccharide (LPS) and BCAA supplementation on blood metabolites and N balance of 20 ruminally-cannulated steers (177 ± 4.2 kg BW).
