Question

In poultry industry, production of hatching eggs is more expensive than the production of market eggs mainly because
a. Cost of males and their depreciation value is high.
b. Mortality among females is usually lower when they are mated with males.
c. The number of eggs produced by hatchery flock are to be sold only as market eggs.
d. Some of the eggs produced by hatchery flocks are not acceptable for incubation.

Answer 1

Poultry farming is the act of raising fowl for egg production and chicken meat. Poultry birds exclusively grown for meat are called broilers (e.g., Plymouth rock). Layers are female fowls raised for egg production. (e.g., White leghorn).

Complete answer:
- Production of hatching eggs is more expensive in the poultry industry because it requires an optimum temperature for its incubation.
- Weight of the hatching egg and chick weight play an important role in this. Under optimal incubation temperature and conditions, the weight of the chick is 67-69% of the weight of the egg. Uniformity of the egg weight results in uniformity of the chick weight.
- Breeder uniformity is responsible for the uniformity in the hatching eggs and the more uniform the breeder flock, the more uniform is the weight of the eggs.
- Thus, some of the eggs produced by hatchery flocks are not acceptable for incubation and are rejected. This makes the production of hatching eggs more expensive than the production of market eggs.

Hence, the correct answer is option (D).

Note: Culling are infected birds that are removed from the flock and killed because they can pass on the infection from their saliva, nasal secretions, and feces.
- Bird flu is avian influenza which can also attack human beings. It was caused by (H5N1) influenza virus in 2003 (Thailand).
- In 1918, bird flu attacked human beings and killed about 50 million humans.
- Some indigenous breeds are Aseel, Busra, Chittagaon, Kadaknath, Ghagus.
- Aseel fowls are used in cock fighting.
