Progeny selection is a breeding method where animals are selected based on the performance and characteristics of their offspring. This method is used to determine the genetic quality of a parent by observing the traits expressed in its progeny. It is commonly used in livestock improvement programs to enhance productivity traits like milk yield, weight gain, or egg production.

(4aii)
Crossbreeding involves mating animals from two different breeds to combine desirable traits from both parents. It is commonly used to improve hybrid vigor or heterosis, which leads to healthier and more productive offspring. Crossbreeding helps to improve traits such as disease resistance, growth rate, fertility, and adaptability to environmental conditions.

(4b)
(PICK ANY FOUR)
(i) It requires highly skilled personnel for proper handling and insemination.
(ii) The success rate can be low if insemination is not done at the right time.
(iii) Equipment used can be expensive to purchase and maintain.
(iv) There is a risk of spreading diseases if proper hygiene is not maintained.
(v) It reduces genetic diversity when a few selected males are overused.
(vi) The semen may be damaged during storage or transportation, reducing fertility.
(vii) It may cause stress to animals if not handled gently.
(viii) In rural areas, facilities for semen storage (like liquid nitrogen) may be unavailable.

(4c)
Genes are segments of DNA that carry instructions for the development of specific traits in an organism, WHILE alleles are the different forms or variations of a gene that determine how the trait is expressed. For example, a gene may control flower color, while the alleles may result in red or white flowers.

=============

(5a)
(PICK ANY TWO)
(i) Vaccination of animals to prevent infections
(ii) Regular sanitation and proper hygiene practices
(iii) Quarantine of infected or new animals before mixing
(iv) Proper disposal of dead animals and waste
(v) Routine veterinary check-ups and treatment
(vi) Providing clean water and balanced nutrition to boost immunity

(5bi)
Deworming is the process of giving animals medication to remove internal parasites such as roundworms, tapeworms, and flukes from their digestive system. Regular deworming helps improve the animal’s health, promotes better feed utilization, increases productivity, and prevents disease outbreaks on the farm.

(5bii)
Drenching is the method of administering liquid medicine directly into the mouth of an animal using a drenching gun or syringe. It is commonly used to treat internal parasites and other infections. Proper drenching ensures accurate dosage and helps maintain the overall health and performance of the animal.

(5c)
(i) Virus – Newcastle Disease
(ii) Bacterium – Fowl Cholera
(iii) Fungus – Aspergillosis
(iv) Protozoan – Coccidiosis
