Health & Behavior
• Alert• Ears ‘normal’• Bright eyes• Head up• Contented,
productive• Playful, easy
movement
• Listless• Dull eyes, pallid skin• Thin, no appetite• Diarrhea or no
bowel movements• Skin rashes,
blemishes• ‘Unkept’ haircoat

![Page 5: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/5.jpg)
• Observe an animals bowel movements– A change (looser, firmer, different color)
can indicate a coming change in health
![Page 6: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/6.jpg)
4 Good Rules

• Reduce Animal Stress– Protection from environment, parasites,
injury
• Know WHEN to call for help

To REPEAT
• ANTIBIOTICS ARE NOT EFFECTIVE AGAINST VIRUSES
• Some antiviral agents do now exist, but are not yet used routinely for animals, except for testing for human use.

• Vaccination
• Castration
• Isolation
• Sanitation
• Herd replacement
![Page 31: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/31.jpg)

• Properly dispose of manure, bedding, and dead animals
• Allow buildings to remain empty (3 wks) to break disease cycle
![Page 33: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/33.jpg)
• Quarantine NEW and DISEASED animals
• Limit movement or contact with man and animals that my carry disease
![Page 34: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/34.jpg)
Keeping Animals HealthyCattle - Prevention
• Buy or breed healthy animals– If possible buy direct from breeder– When animals are sent to concentration
points• Unfavorable environment• Fed, watered irregularly• Mixed with other animals
![Page 35: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/35.jpg)
Preconditioning
• Prior to placing in feedlot– Varies with:
• Age• Origin• Procurement method• Vaccination history• Mgmt procedures applied
• MORE than just a NEEDLE program
![Page 36: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/36.jpg)
• Carefully timed program of:– Weaning– Feed and water adaptation– Immunization– Treatment & reduced marketing stresses
• Want a healthy, disease resistant animal that will readily adjust
![Page 37: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/37.jpg)
Preconditioning Practices
• Surgical procedures– Castrate & dehorn well in advance of
shipping
• Parasite control– Treat for internal parasites– Treat for grubs & lice
![Page 38: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/38.jpg)
• Vaccinations– Blackleg – malignant edema – clostridium– Parainfluenza 3– Pasteurella– IBR– BVD– PROBABLY – work list with your VET
![Page 39: Health Animal Health and Disease. Sources of Information Keeping Livestock Healthy: A Vet guide to Horses, Cattle, Pigs, Goats & Sheep. Haynes. Publisher:](https://reader036.fdocuments.in/reader036/viewer/2022062314/56649e185503460f94b045f7/html5/thumbnails/39.jpg)
• Wean calves at least 3 weeks before shipping
• Feeding– Start on hay and grain at least 3 weeks
ahead
• Feeder must expect and be willing to pay more for preconditioned animals

• Transport animals under the best possible conditions
• Inspect animals immediately upon arrival
• Give cattle access to water & long hay– Also protein supplement– Antibiotics help reduce disease
