Aflatoxicosis in feedlot cattle

Journal of the American Veterinary Medical Association, 1985
Aflatoxicosis was diagnosed in lightweight feedlot cattle fed aflatoxin-contaminated cottonseed or gin trash. Clinical signs of hepatic damage and death were recorded for more than 200 of the 14,000 animals in a feedlot. Aflatoxin concentration in feedlot products fed to these cattle ranged from 96 to 1,700 ng/g.

Osteochondrosis in Feedlot Cattle

Veterinary Pathology, 1981
Beginning in summer 1977 and continuing through four consecutive seasons, we examined lame limb joints from 106 partially fattened cattle and 28,235 pairs of occipital condyles from fully fattened cattle for osteochondrosis. Of the 106 lame cattle, nine (8.5%) had characteristic lesions, usually in their stifle joints, and of the 28,235 atlanto ...

Acidosis in Feedlot Cattle

Veterinary Clinics of North America: Food Animal Practice, 2007
Mortality from digestive diseases in feedlot cattle is second only to that from respiratory diseases. Acidosis is a major digestive disorder and is likely to continue because of ongoing attempts to improve the efficiency of beef production by feeding more grain and less roughage.

Hypovitaminosis A in feedlot cattle

Journal of the American Veterinary Medical Association, 1987
Hypovitaminosis A was diagnosed in a group of feedlot cattle that had been fed a diet low in carotene for 18 months. The primary signs of disease in the cattle were poor weight gain, ataxia, convulsions, night blindness, and total blindness. Serum vitamin A concentrations were used to confirm the diagnosis.

Bronchiectasis in Yearling Feedlot Cattle

Journal of the American Veterinary Medical Association, 1976
SUMMARY Throughout all of 1974, we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle. From the 3,943 dead cattle, 1,988 necropsies were made; of the cattle necropsied, 32 (1.6%) had bronchiectasis. In this disease, the permanently dilated small bronchi and bronchioles, located in ventral parts of the lungs, were filled with ...

Liver Abscesses in Feedlot Cattle

Veterinary Clinics of North America: Food Animal Practice, 2007
Liver abscesses in feedlot cattle result from aggressive grain-feeding programs and are influenced by a number of dietary and management factors. They have a major economic impact on the feedlot industry because of liver condemnation and reduced animal performance and carcass yield.

Dust Emissions in Cattle Feedlots

Veterinary Clinics of North America: Food Animal Practice, 1988
Dust emissions were measured at three Texas cattle feedlots on 15 occasions in 1987 to determine concentrations of total suspended particulate matter (TSP) and dust with 10 microns or less aerodynamic particle size (PM-10). Net feedlot dust concentrations (downwind minus upwind) ranged from 15.7 to 1,700.1 micrograms per m3 and averaged 412.4 +/- 271.2

Abomasal erosions in feedlot cattle

American Journal of Veterinary Research, 1992
Summary The abomasa of 1,949 slaughtered feedlot cattle, 45 necropsied feedlot cattle that died 2 to 45 days after arrival, and 45 necropsied pastured cattle were opened and examined. Of these organs, 484,1, and none, respectively, contained erosions. The slaughtered cattle were fattened at 3 locations: 1,305 with 430 eroded abomasa were fed a ration ...

Zygomycotic Lymphadenitis in Slaughtered Feedlot Cattle

Veterinary Pathology, 2009
During the 12 months of 2006, zygomycotic lymphadenitis was diagnosed in 194 of 198 feedlot steers (0.04% of cattle slaughtered during that period) in a California slaughterhouse as part of bovine tuberculosis surveillance. Mesenteric lymph nodes were involved in 190 cases.
