"I think using animals for food is an ethical thing to do, but we've got to do it right. We've got to give those animals a decent life and we've got to give them a painless death. We owe the animal respect."

7Beef Cattle Cow/Calf ProducersNE,TX, KS
- Before the feedlot, spend most of their time in
open range or field settings. - Handled and restrained only occasionally
vaccination and deworming. - Suspicious of humans and enclosures (pens and
chutes), and are usually more difficult to
segregate and restrain. - Caution Beef bulls and cows with calves
8Dairy cattle
- Temperament
- nervous cow
- the docile cow
- the balker (obstinate)

9Dairy Cattle
- Dairy cattle are handled more frequently and
spend much less time in open settings. - Dairy cows are milked twice daily while
lactating, and the lactation cycle lasts on
average 8-10 months of the year. - Breeding is done by artificial insemination.
- Calves are often reared in enclosures with
frequent human contact. - In generaL, dairy cattle tend to be much easier
to handle and restrain. (Caution on dairy bulls
and mums)
10Cattle Restraint
- Stress
- Loss of production results in lower profits.
- Increased feed requirements result in increased
cost. - Decreased immunity results in increased illness.
- Death results in lower profits.
11Cattle Restraint (contd)
- Stress
- Increased respiration
- High mortality
- Teeth grinding
- Poor product quality
- Nervousness
- Poor growth rate
- Poor reproduction
- Increased flight zone
12Most veterinarian procedures required two stages
of animal handling
- The individual most be separate from the herd
(herding instinct) - The individual must then be restrained
appropriately for the procedure
13Restraint
- Chemical and physical restraint
- Prepare
