CattleMaster Gold FP5 VL5
several injectable products are used in pre-calving and post-calving protocol that are not considered vaccines. Name one of these products and describe specifically what the possible benefit to the cow or calf might be
Multimin
this injection helps the cow get zinc, copper, selenium, and manganese for proper nutrition
provides supplementation
What are the numerical body condition scores for beef cattle? What is the optimal BCS range for a group of cows near calving?
1-9
5-7 is optimum for breeding
We body condition score all of close-up pregnant cows in lab. BCS is typically done prior to calving but can be useful during other times of the production year. What would be one example of a production problem associated with cows that are too thin at calving?
They may be fatigued while calving and will need assistance during delivery
fail to conceive and cycle
What was the commercial name of the dewormer used in pre-calving protocol? How was the product administered to the cows?
SafeGuard
orally
Which vaccine was used in the pre-calving processing that will help protect against late term abortions
Cattlemaster gold FP5 VL5
what is the term used to describe the distance that cattle can be from the handlers and still feel comfortable?
flight zone
What is the term used to describe the location of the handler relative to the animals shoulder where movement forward or backward can be infulenced ?
point of balance
What is a toxoid vaccine? Name one we used in our pre-calving processing
when vaccine protects against specific toxinx by rcontaining anitbodies
ScourBos 9
On a score on 1-6, which score represents the mildest disposition?
1
what is the temperament classification of disposition
very aggressive
Since cattle are not able to talk, how do they communicate with each other?
by signaling with body movement and calling out
Stress can compromise the health of otherwise normal cattle. What would be two examples of ways to reduce stress when handling cattle
move quietly
work in groups
We vaccinate all cows and heifers prior to calving with Covexin 8. Name two diseases targeted by Covexin 8 vaccine

tetanus
how to use calf puller
place on back side of cow, chain over the hops, being sure the tail isnt caught. Then you attach the chain on the feet of the calf to the puller and crank while stationing the puller at a down angle
What does EID represent
Electronic identification

First clean the exposed area, then you would carefully push the prolapse back in, stitching is needed to make sure the prolapse does not reoccur
what is calf head snare used for
make sure head placement stays correct during birth
briefly describe the most important steps of freeze branding starting with
a. cool the branding irons and restrain the animal
b. shave a square in desire area
c. clean area with alcohol to remove oils
d. align and firmly press brand with rocking motion to area for 45 sec
e. place branding irons back into coolant
What is OB chains and puller used for
used to pull the calf out of the cow if there is difficulty during birth
what is the most significant difference between using liquid nitrogen or dry ice and alcohol for freeze branding?
liquid nitrogen will get colder faster
dry ice and alcohol will stay colder longer
Which type of RFID ear tag allows for reading from 3 ft away
half duplex
Which type if RFID ear tag is approved by the USDA animal disease and traceability identification
half duplex
If done properly, a freeze brand will be visible as what on black cattle? What actually happens to the skin of a colored calf if freeze branded properly
it will be visible as white hair where the brand was
the color pigment in the hair follicle is destroyed which results in growth of white hair
You observe a cow giving birth. You see two feet coming out. If the tips of the feet are pointing down and the hoof sole is pointing up, is delivery normal or breech?
breech
Why is it more likely for a first calf heifer to have calving difficulties than the cow?
It is easier for the calf to get stuck, since the first calf heifer is smaller
If you were to sample your forages and send those samples off to a forage analysis lab to determine the nutrient composition, what would be the two most important nutrients in the feed that help you balance a ration
protein and energy
If you harvested 100 large round bales of first cutting hay, how many bales (min) should you core sample and compile for an accurate forage analysis
10 bales minimum
