(ii) Oxytocin: Stimulates uterine contractions during parturition (birth) and milk letdown during lactation.
(iii) Relaxin: Relaxes the pelvic muscles and widens the pelvis to facilitate parturition.
(iv) Testosterone: Regulates male reproductive traits and secondary sex characteristics.
(1c)
(i) Food source: Snails are a protein-rich food source, consumed in many parts of the world.
(ii) Medicinal value: Snail slime has medicinal properties, used in skincare and wound healing.
(iii) Economic benefits: Snail farming can provide income and employment opportunities.
(iv) Environmental benefits: Snails help control pest populations and maintain ecosystem balance.

QUESTION 2
(2ai)
Piglet at birth:
-Colostrum management
-Farrowing management
(2aii)
Kitten after weaning:
-Vaccination and health management
-Nutrition and feeding management
(2b)
(i) Improved nutrition and feeding practices.
(ii) Enhanced cow comfort and welfare.
(iii) Regular health monitoring and disease prevention.
(2c)
(i) Traditional markets: Local markets where hides and skin are sold to traders and artisans.
(ii) Auctions: Organized sales where hides and skin are sold to the highest bidder.

QUESTION 3
(3a)
Diet in animal nutrition refers to the combination of foods and nutrients that an animal consumes to meet its nutritional needs for maintenance, growth, and production.
(3b)
(i) Energy source: Molasses provides a readily available energy source for microorganisms during fermentation, promoting a desirable acidic environment.
(ii) Palatability: Molasses adds sweetness, making the silage more appealing to animals, which can improve feed intake and digestion.
(3c)
(i) High yield: Produces a large quantity of forage to support animal production.
(ii) Nutritional quality: Provides a balanced mix of nutrients, including protein, energy, and minerals.
(iii) Persistence: Remains productive and healthy over time, withstanding grazing and environmental stresses.
(3d)
(i) Rotational grazing: Managing grazing periods and rest periods to prevent overgrazing and allow vegetation recovery.
(ii) Re-seeding and re-vegetation: Introducing new grass species and re-vegetating degraded areas to enhance pasture quality and productivity.
(iii) Brush control: Managing woody plants and brush to reduce competition and promote grass growth.
===================================================
QUESTION 4
(4a)
In animal improvement, a gene is a fundamental unit of heredity located on chromosomes that contains the DNA sequence which encodes the information necessary for the synthesis of proteins and ultimately determines specific traits in an animal.
(4b)
Diagram
(4c)
(i) Low conception rate: Failure to achieve pregnancy despite successful insemination.
(ii) Semen quality issues: Poor semen quality or quantity can reduce fertility.
(iii) Inaccurate heat detection: Failure to detect the optimal breeding time, reducing conception chances.
(iv) Insemination technique errors: Improper insemination technique can lead to reduced fertility.
(v) Disease transmission: Risk of transmitting diseases or infections through semen or insemination equipment.

(ii) Health status determination: Observing animals for signs of disease or infection before introducing them to a new herd or flock.
(5c)
(i) Anemia: Mite feeding can lead to blood loss and anemia.
(ii) Weight loss: Infested animals may lose weight due to discomfort and reduced feed intake.
(iii) Skin irritation: Mite bites can cause skin irritation, inflammation, and lesions.
(iv) Reduced productivity: Infested animals may experience reduced milk production, egg laying, or growth rates.
(v) Stress and discomfort: Mite infestation can cause significant stress and discomfort for the animals.
