ANIMAL SCIENCE PRACTICAL ANSWERS
(1a)
A milk churn or milk collection container
(1b)
It is used for removing impurities such as dirt, hair, or other particles during the milking process.
(1c)
A: Neck of the churn
B: Body of the churn
C: Base of the churn
D: Handle
(1d)
In dairy farming, particularly with cows, this structure is used to ensure that milk collected during milking is free of contaminants like dust, straw, or foreign particles.
(1e)
The milk in the churn is preserved by keeping it at low temperatures to slow bacterial growth.
(1f)

ADVANTAGES;
(i) Hygienic milk collection and storage
(ii) Easy to transport milk over short distances
(iii)
Durable and reusable for multiple uses.
DISADVANTAGES;
(i) Limited capacity for milk storage.
(ii) Requires regular cleaning to avoid spoilage
(iii) Can be heavy when filled with milk.
=======================================
(2a)
A male reproductive system
(2b)
A - Glans
B - Epididymis
C - Scrotum
D - Testis
E - Cowper's gland
F - Vas deferens
(2c)
A (Glans): It contains a high concentration of nerve endings, making it sensitive to touch and stimulation.
B (Epididymis): It transports sperm to the vas deferens during ejaculation.
D (Testis): It produces testosterone, which regulates male characteristics, libido, and fertility.
(2d)
In a bull, the testis produces sperm, which is essential for the fertilization of the cow's egg during breeding.
(2e)
Testosterone
=======================================
(3a)
Chicken egg
(3b)
A - Germinal disc
B - Shell membrane
C - Chalaza
D - Air cell
E - Egg Shell
F - Albumen
G - Yolk
(3c)
(i) Eggs are a source of protein and nutrients.
(ii) Fertilized eggs are incubated to produce chicks.
(iii) Eggs are used as a binding agent in baking
(3d)
(i) Leghorn
(ii) Rhode Island Red
(iii) Barred Plymouth Rock
(iv) Golden Comet
(3e)
(i) Lack of essential nutrients in the hen's diet.
(ii) Infections or illnesses affecting the hen's reproductive system.
(iii) Environmental stressors such as overcrowding or extreme temperatures.
(3f)
(i) Fertilization: The egg must be fertilized by a rooster.
(ii) Incubation: The egg must be incubated at the correct temperature and humidity.
