iCEV Unit 1 Quiz

Why would a farmer choose artificial insemination over natural breeding methods for their dairy operation?

• It is less expensive than keeping male animals
• It produces more offspring per breeding cycle
• It eliminates the need for pregnancy monitoring
• It allows access to superior genetics without housing bulls
• It requires less veterinary supervision

A dairy farmer notices that milk production drops significantly after 305 days. What management decision should they make and why?

• Switch to beef production
• Supplement with artificial hormones
• Immediately breed the cow again
• Increase feed rations to boost production
• Allow the cow to become dry to prepare for next calf

Compare the gestation periods: If a farmer breeds a cow, mare, and sow on the same day, which sequence represents when each will give birth?

• Mare (336 days), cow (283 days), sow (114 days)
• All three will give birth within the same month
• Sow (114 days), cow (283 days), mare (336 days)
• Sow (114 days), mare (336 days), cow (283 days)
• Cow (283 days), sow (114 days), mare (336 days)

Why is colostrum critical for newborn survival compared to regular milk?

• It provides essential antibodies and disease resistance
• It contains more water to prevent dehydration
• It is easier for newborns to digest
• It stimulates faster muscle development
• It contains more calories for rapid growth

How does the four-compartment stomach system benefit cattle production compared to single-stomach animals?

• It produces higher quality meat products
• It enables digestion of grasses and fibrous materials humans cannot use
• It allows for faster weight gain
• It allows cattle to eat less food overall
• It reduces the need for veterinary care

A livestock producer wants to maximize efficiency in their swine operation. What advantage does litter bearing provide?

• Disease transmission is minimized
• Individual piglets are larger at birth
• Gestation period is significantly shorter
• Multiple offspring per breeding cycle increases productivity
• Feed costs are reduced per animal

Why are hog organs particularly valuable for medical research and treatment?

• They contain unique proteins not found elsewhere
• They are easier to harvest and preserve
• They are larger than other animal organs
• They closely resemble human organs in structure and function
• They regenerate faster than other animal tissues

What economic factor likely contributed to chicken becoming 'America's white meat' in the early 1990s?

• Health concerns about red meat consumption
• International trade agreements favoring poultry
• Government subsidies for poultry farmers
• Mass-production operations reducing costs and increasing availability
• Technological advances in refrigeration

A farmer has both fertilized and unfertilized chicken eggs. How should they manage these for maximum economic benefit?

• Sell fertilized eggs for food and incubate unfertilized ones
• Incubate all eggs to produce more chickens
• Use fertilized eggs for chick production and unfertilized for food
• Mix both types together for uniform products
• Store all eggs until market prices improve

Which factor most significantly impacts the terminology used for cattle at different life stages?

• Geographic location of the farm
• Intended market purpose
• Weight and size of the animal
• Age and reproductive status
• Breed and genetic background
