A multifactorial disease of CATTLE resulting from complex interactions between environmental factors, host factors, and pathogens. The environmental factors act as stressors adversely affecting the IMMUNE SYSTEM and other host defenses and enhancing transmission of infecting agents.

A species of gram-negative, facultatively anaerobic, rod-shaped bacteria normally commensal in the flora of CATTLE and SHEEP. But under conditions of physical or PHYSIOLOGICAL STRESS, it can cause MASTITIS in sheep and SHIPPING FEVER or ENZOOTIC CALF PNEUMONIA in cattle. Its former name was Pasteurella haemolytica.

A species of gram-negative bacteria that causes MYCOPLASMA PNEUMONIA OF SWINE. The organism damages the CILIA in the airways of the pig, and thus compromises one of the most effective mechanical barriers against invading pathogens. The resulting weakening of the IMMUNE SYSTEM can encourage secondary infections, leading to porcine respiratory disease complex.

A sulfanilamide that is used as an anti-infective agent.

A chronic, clinically mild, infectious pneumonia of PIGS caused by MYCOPLASMA HYOPNEUMONIAE. Ninety percent of swine herds worldwide are infected with this economically costly disease that primarily affects animals aged two to six months old. The disease can be associated with porcine respiratory disease complex. PASTEURELLA MULTOCIDA is often found as a secondary infection.

Infections with bacteria of the family PASTEURELLACEAE.

Diseases of domestic cattle of the genus Bos. It includes diseases of cows, yaks, and zebus.

Domesticated bovine animals of the genus Bos, usually kept on a farm or ranch and used for the production of meat or dairy products or for heavy labor.

A species of gram-negative bacteria causing MASTITIS; ARTHRITIS; and RESPIRATORY TRACT DISEASES in CATTLE.

Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.

A species of gram-negative, facultatively anaerobic, rod-shaped bacteria normally found in the flora of the mouth and respiratory tract of animals and birds. It causes shipping fever (see PASTEURELLOSIS, PNEUMONIC); HEMORRHAGIC BACTEREMIA; and intestinal disease in animals. In humans, disease usually arises from a wound infection following a bite or scratch from domesticated animals.

A cholinesterase inhibitor that is used as a systemic insecticide, an acaricide, and nematocide. (From Merck Index, 11th ed)

Macrolide antibiotic obtained from cultures of Streptomyces fradiae. The drug is effective against many microorganisms in animals but not in humans.

A methylsulfonyl analog of CHLORAMPHENICOL. It is an antibiotic and immunosuppressive agent.

The reduction or regulation of the population of noxious, destructive, or dangerous plants, insects, or other animals. This includes control of plants that serve as habitats or food sources for animal pests.

Infections with bacteria of the genus PASTEURELLA.

A species of RESPIROVIRUS, subfamily PARAMYXOVIRINAE, most often seen in conjunction with a secondary infection of MANNHEIMIA HAEMOLYTICA resulting in pneumonic pasteurellosis (PASTEURELLOSIS, PNEUMONIC).

A species of CORONAVIRUS infecting neonatal calves, presenting as acute diarrhea, and frequently leading to death.

A species of PNEUMOVIRUS causing an important respiratory infection in cattle. Symptoms include fever, conjunctivitis, and respiratory distress.

Permanent deprivation of breast milk and commencement of nourishment with other food. (From Stedman, 25th ed)

Observation and acquisition of physical data from a distance by viewing and making measurements from a distance or receiving transmitted data from observations made at distant location.

Foodstuff used especially for domestic and laboratory animals, or livestock.

A large family of narrow-leaved herbaceous grasses of the order Cyperales, subclass Commelinidae, class Liliopsida (monocotyledons). Food grains (EDIBLE GRAIN) come from members of this family. RHINITIS, ALLERGIC, SEASONAL can be induced by POLLEN of many of the grasses.

Increase in BODY WEIGHT over existing weight.

Nutritional physiology of animals.

A process involving chance used in therapeutic trials or other research endeavor for allocating experimental subjects, human or animal, between treatment and control groups, or among treatment groups. It may also apply to experiments on inanimate objects.

The science of breeding, feeding and care of domestic animals; includes housing and nutrition.

A disease of the horny parts and of the adjacent soft structures of the feet of cattle, swine, and sheep. It is usually caused by Corynebacterium pyogenes or Bacteroides nodosus (see DICHELOBACTER NODOSUS). It is also known as interdigital necrobacillosis. (From Black's Veterinary Dictionary, 18th ed)

The group in which legal authority is vested for the control of health-related institutions and organizations.

The faculty of expressing the amusing, clever, or comical or the keen perception and cleverly apt expression of connections between ideas that awaken amusement and pleasure. (From Random House Unabridged Dictionary, 2d ed)

Examination of the mouth and teeth toward the identification and diagnosis of intraoral disease or manifestation of non-oral conditions.

Images used to comment on such things as contemporary events, social habits, or political trends; usually executed in a broad or abbreviated manner.

The distal extremity of the leg in vertebrates, consisting of the tarsus (ANKLE); METATARSUS; phalanges; and the soft tissues surrounding these bones.
