BRD detection in calves: what 100 calves showed
Feeding behavior data picked up 69.9 percent of bovine respiratory disease events in pre-weaned calves in one machine learning study. The most balanced model landed at 56.0 percent alert accuracy and 69.1 percent disease detection accuracy across 223 disease events. Early BRD detection matters because antibiotics and anti-inflammatory drugs such as flunixin need time to work before lung damage sets in. Why BRD is hard to catch early in pre-weaned calves Bovine respiratory disease sits at the top of the health problems that hit young calves. It spreads widely, costs real money, and it leaves a mark on performance that lasts long after the infection clears. A sick calf gives…

Feedlot chronic pens: what 52,886 cattle show
Chronic is not the same as condemned. Most cattle moved to feedlot chronic pens still reach market weight: 62 percent of 52,886 chronic animals tracked across 17 operations and seven years of records shipped at full weight. Respiratory disease led the diagnosis groups at a median 45.2 percent, lameness came second at 23.9 percent, and mortality took 23.1 percent. The spread between yards is wider than any of those figures. Why feedlot chronic pens have been so poorly described Beef production talks about animal welfare constantly. Industry policy books carry sections on cattle well-being, and the international animal health code has a chapter covering beef systems. The animals that actually…
