Q

Is Fecal egg count reflective of the number of adults in the GIT

A

No it is no because the parasites make eggs at different rates and the number of eggs is not pathogenic

Q

Strongylids horses and hypobiosis with the weather

A

Cold: parasites die or slow development
 Fall : high L3 and eggs
 Winter : decrease in L3 and eggs

Warm: speeds development
 Winter to spring :
• Eggs develop in warm weather
• L3 released in fall are gone by spring ; then new L3 develop in spring

Q

Is there a consistent vaccination protocol in cattle?

A

NO
Every farm, every operation will have DIFFERENT needs, methods of management and production goals – therefore each farm will need a vaccination protocol tailored to their system.

30
During small ruminant quarantine after purchase
Vaccinate  Gradually adjust grain diet (if receiving grain)  Serology– Johne’s, CL, CAE/ OPP  Deworm (epg reduction test)  Trim feet —Foot rot
31
How many acres per small ruminant vs cow calf
5 small ruminants = 1 cow/calf unit 1 cow/ calf unit requires 2-3 acres pasture
32
Do you prefer colostrum replacer or supplement for small ruminant?
Colostrum replaces 200ml/kg in first 12 hours
33
When to castrate small ruminant?
1st week of life Dam needs tetanus toxoid vaccine so the small ruminant baby is too young and give young antitoxin at band placement —banding
34
Cattle 5 freedoms from
Hunger/thirst Discomfort Pain or injury Fear or stress To express normal behavior
35
Hay vs straw Hay vs haylage
Hay : to eat the grass part Straw : Stalk tubular and warmer for bedding [sometimes horses are stupid and eat this] Hay vs haylage: haylage has less storage and field losses
36
Is a trace mineral salt or block enough as mineral supplementation for cattle?
NO They need minerals that is NOT that much NaCl
37
Nutrition of cattle is best checked by… What do you use to tell if a beef cow is 4/9 or 5/9
Beef cattle = BCS — use the tail head to tell —4/9 the transverse processes visible but not individually vs 5/9 not visible Dairy cattle = Monitor weight not BCS Energy reserve eval =BCS
38
Beef vs Dairy : Breed season vs the breeding year How long is the calving interval
The breeding season over 65 days for the beef cattle =12 months — live cover The breeding year for the diary cattle =13.5 months — AI
39
What are the goals of a beef cow
Get pregnant Calve well Nurse till weaning
40
When to give cattle vaccine
◦ Frequent Diseases ◦ Fatal Diseases ◦ Financially sound ◦ EFFective vaccines
41
what type of vaccine stimulates IGA production in very young calves under a week old
intranasal vaccine of modified live For IBR PI3 BRSV —-this is because the IGA that is gotten from colostrum is gone by 3 to 4 days
42
When is active immunity the highest versus passive immunity?
Active immunity is getting higher than passive at weaning The switch happens at 3 to 4 months
43
Postpartum anestrus duration is affected by
the age of the cow and the body condition of the cow at Calving Thinner cows have a longer anestrus . Cows that are giving birth for the first time have a longer time till they return to cycling120d vs 50-80

• To make cattle **speed up, walk against their direction of travel** • To make them **slow down, walk with them.** • To make them **go forward, walk towards their tail** • To make them go backwards, walk towards their head
47
Why is colostrum so important?
Cattle are born without active immunity so they have to survive with passive immunity from colostrum for the first 4 to 5 weeks FEED 4L IN AT BIRTH [<1-2hr] — 5.2 g/dl TOTAL PROTEIN
48
How does heat treatment affect the immunoglobulins that colostrum offers?
Heat treatment of colostrum decreases the bacteria which enables better absorption It doesn’t affect the amount of immunoglobulins

• FAMACHA system is different than using the FAMACHA card o The system is to use the card on every animal every 2 weeks throughout the grazing season from may to September
51
Best tool for generic selection in sheep
Fecal egg count- this is because there is a hearibility of immunity from haemonchus contortus — the egg count illustrates the animals that have fewer worms and are more tolerant —good relation to the worm burden unlike in horses
52

58
What type of Ketosis is more likely to happen right at calving?
Secondary Ketosis be cause it is another issue that is not letting the cow eat as much as it needs to Primary – occurs @ peak lactation; cow CANNOT eat enough to support heavy milking Secondary – occurs in the fresh period; something is causing cow to NOT eat enough

65
Main reason for culling a sow is ’ Poor performance ’ Fail to return to heat ’ Lameness
Lameness!! But all are reasons

71
American foulbrood versus European foulbrood
The American Food is spore forming so you have to incinerate to get rid of the bacteria Where is the European foulbrood is not spore forming so if possible just isolate the queen and don’t let her create a new brood and the bacteria will leave
