Q: A poultry farm wants to calculate the stocking density using the following data: average body weight (BW) is 2 kg/bird, total number of birds (n) is 5000, and total available area (A) is 1000 $$m^2. $$What is the stocking density ($$SD$$)? $$SD = \frac{BW \times n}{A}$$

$$SD = \frac{2 \times 5000}{1000} = 10$$

Q: A welfare assessment protocol uses the following formula to determine the measure score for the absence of hunger: $$I = 6.5 - \frac{p}{6.5} \times 100. If 1$$% of birds are emaciated ($$p = 1$$), what is the measure score $$I$$?

$$I = 6.5 - \frac{1}{6.5} \times 100 = 6.5 - 15.38 = -8.88$$

Question 1

A poultry farm wants to calculate the stocking density using the following data: average body weight (BW) is 2 kg/bird, total number of birds (n) is 5000, and total available area (A) is 1000 $$m^2. $$What is the stocking density ($$SD$$)?

$$SD = \frac{BW 	imes n}{A}$$

Accepted Answer

$$SD = \frac{2 	imes 5000}{1000} = 10$$

Question 2

Why is it not recommended to use a hook to catch broiler chickens in commercial systems?

Accepted Answer

Broilers are young and their bones are not strong

Question 3

Which of the following is a disadvantage of the cage system for laying hens?

Accepted Answer

Limited living space and enrichments

Question 4

A welfare assessment protocol uses the following formula to determine the measure score for the absence of hunger: $$I = 6.5 - \frac{p}{6.5} 	imes 100. If 1$$% of birds are emaciated ($$p = 1$$), what is the measure score $$I$$?

Accepted Answer

$$I = 6.5 - \frac{1}{6.5} 	imes 100 = 6.5 - 15.38 = -8.88$$

Question 5

Which welfare principle is assessed by measuring the absence of prolonged thirst and drinker space?

Accepted Answer

Good feeding (& drinking)

Question 6

A poultry house is evaluated for litter quality at 20 spots. The 15th percentile spot has a scale of 3. According to the scoring table (4=0, 3=14, 2=34, 1=67, 0=100), what is the litter quality score for the house?

Accepted Answer

14

Question 7

Which of the following is a welfare concern specifically associated with broiler chickens?

Accepted Answer

Walking ability due to rapid growth

Question 8

Which of the following is a correct interpretation of the Global Animal Partnership (GAP) 5-step® Animal Welfare Program?

Accepted Answer

Higher step numbers indicate higher welfare standards and more natural environments

Question 9

Which poultry body part can be used to predict the color of eggs a hen will lay?

Accepted Answer

Earlobe

Question 10

A farm receives the following principle scores: Feeding/Drinking = 80, Housing = 70, Health = 70, Behavior = 60. According to the welfare category criteria, what is the farm's welfare category?

Accepted Answer

Enhanced

Question 11

Which of the following is a direct advantage of the cage system for laying hens?

Accepted Answer

Separation from manure, reducing ammonia concentration

Question 12

Which welfare measure is most likely to be affected if the poultry house has poor ventilation and high humidity?

Accepted Answer

Litter quality

Question 13

If a poultry house has a high percentage of birds with severe plumage dirtiness, how will this affect the plumage cleanliness score using the formula $$I = 100 - 2 	imes \%slight + 7 	imes \%moderate + 13 	imes \%severe / 13$$?

Accepted Answer

The score will decrease, indicating poorer welfare

Question 14

Which of the following is NOT a welfare criterion under the principle of 'Good health'?

Accepted Answer

Absence of prolonged thirst

Question 15

A poultry house is assessed for panting and huddling. In one area, more than half the birds are panting. According to the scoring table (4=19, 3=29, 2=39, 1=69, 0=100), what is the score for this area?

Accepted Answer

29

Question 16

Which of the following is a real-world consequence of high stocking density in broiler production?

Accepted Answer

Reduced walking ability and increased risk of lameness

Question 17

Which poultry body part is commonly evaluated as part of welfare assessment due to its susceptibility to injury or dermatitis?

Accepted Answer

Hock

Question 18

Which of the following best describes the bottom-up strategy for welfare assessment?
