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 ...

Feedlot Cattle Pneumonias

Veterinary Clinics of North America: Food Animal Practice, 1985
The etiology, epidemiology, clinical signs, and pathology of feedlot cattle pneumonias are discussed. This information enables a clinician with a feedlot cattle pneumonia problem to give prompt, useful advice on cause, prevention, and treatment based on findings of the feedlot visit.

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.

Marbling in feedlot cattle

Australian Journal of Experimental Agriculture and Animal Husbandry, 1974
The degree of marbling and the thickness of subcutaneous fat at the 10th rib cut of the M. longissimus was studied in three groups of 450 kg Santa Gertrudis crossbred and Hereford steers fattened for 120 days on three grain-based diets in a commercial feedlot.

Laryngeal Diphtheria and Papillomatosis in Feedlot Cattle

Veterinary Pathology, 1981
In a random sample of 30,444 larynges from slaughtered beef cattle, 441 (1.4%) had chronic diphtheria and 1,345 (4.4%) had papillomatosis. Both types of lesions were centered in mucous membranes over the vocal processes and medial angles of the arytenoid cartilages.

Processing of Corn and Sorghum for Feedlot Cattle

Veterinary Clinics of North America: Food Animal Practice, 2007
Approximately 75% to 80% of expenses involved in cattle feeding in commercial feedlots are feed costs. Grains are used in feedlot diets to improve the performance and efficiency of feedlot cattle by increasing the energy density of diets. Grains for these diets are commonly processed for various reasons, including improving palatability, altering ...

Feedlot Processing and Arrival Cattle Management

Veterinary Clinics of North America: Food Animal Practice, 2015
Acclimating newly arrived cattle in a feedlot setting can increase cattle confidence, reduce stress, improve immune function, and increase cattle well-being. Understanding cattle instincts and using low-stress handling techniques teaches cattle to trust their caregivers and work efficiently for them throughout the feeding period.

Diseases of Yearling Feedlot Cattle in Colorado

Journal of the American Veterinary Medical Association, 1976
SUMMARY During all of 1974 we surveyed, for illnesses and deaths, about 407,000 yearling feedlot cattle. The morbidity was 5.1%, with a case mortality of 18.9% and a population mortality of 1.0%. Both morbidity and mortality were higher during fall and winter than during spring and summer. Of the 3,943 dead cattle, 1,988 were necropsied.

Suspected monensin toxicosis in feedlot cattle

Australian Veterinary Journal, 1985
SummarySuspected monensin toxicosis was seen in feedlot cattle aged 6 to 9 months. Twenty cattle died following inclusion of monensin in the feed at 400g/tonne, which was 13 times the recommended level. The deaths occurred over 2 weeks. Clinical signs were inappetance, respiratory distress and sudden death.
