CPT CPT Flock Management & Production Systems 1 — Questions and Answers
Question 1: What is the standard stocking density recommendation for broiler production in the US to maintain bird welfare?
- 6 lbs/sq ft (Correct answer)
- 8 lbs/sq ft
- 4 lbs/sq ft
- 10 lbs/sq ft
Correct answer: 6 lbs/sq ft
The standard broiler stocking density is approximately 6 lbs per square foot of floor space to balance welfare and production efficiency.
Question 2: Which lighting program is most commonly used during the grow-out phase of broiler production to promote feed intake?
- Continuous 24-hour light
- 23 hours light / 1 hour dark (Correct answer)
- 16 hours light / 8 hours dark
- 12 hours light / 12 hours dark
Correct answer: 23 hours light / 1 hour dark
A 23L:1D photoperiod is widely used in broiler grow-out to maximize feed intake while providing a brief dark period for birds to rest.
Question 3: What internal temperature should a poultry house be maintained at during the first week of broiler chick placement?
- 85-90°F (29-32°C)
- 75-80°F (24-27°C)
- 95-100°F (35-38°C) (Correct answer)
- 70-75°F (21-24°C)
Correct answer: 95-100°F (35-38°C)
Day-old chicks require brooding temperatures of 95-100°F (35-38°C) during the first week because they cannot yet thermoregulate effectively.
Question 4: Which production system uses a multi-age site arrangement where different flocks of varying ages are housed on the same farm?
- All-in/all-out
- Multi-age production (Correct answer)
- Cage-free system
- Free-range system
Correct answer: Multi-age production
Multi-age production places flocks of different ages on the same site, increasing disease transmission risk compared to all-in/all-out systems.
Question 5: What is the primary purpose of litter management in broiler houses?
- Improve bird coloring
- Reduce ammonia levels and maintain flock health (Correct answer)
- Increase feed efficiency
- Lower electricity costs
Correct answer: Reduce ammonia levels and maintain flock health
Proper litter management reduces ammonia accumulation, controls moisture, and limits pathogen load, all of which directly impact flock health.
Question 6: In a pullet house, at what age are laying hens typically transferred to the layer house in commercial egg production?
- 8-10 weeks
- 14-16 weeks (Correct answer)
- 4-6 weeks
- 20-22 weeks
Correct answer: 14-16 weeks
Pullets are typically moved to the layer house at 14-16 weeks of age to allow them to acclimate before onset of egg production around 18-20 weeks.
