Oestrus cycle is a reproductive cycle that occurs in most female mammals including humans. It refers to the regular pattern of hormonal changes and physiological events that prepare the female for reproduction.
(1b)
(i) Antibodies: Colostrum is rich in antibodies also known as immunoglobulins which help provide passive immunity to newborns. These antibodies are transferred from the mother to the baby and help protect against various infectious diseases by enhancing the baby’s immune system.
(ii) Growth factors: Colostrum contains essential growth factors that aid in the growth and development of the newborn. These growth factors stimulate the production of new cells enhance tissue repair and regeneration and promote overall growth and development in the early stages of life.
(1c)
(PICK ANY THREE)
(i) Progesterone maintains pregnancy in mammals.
(ii) Progesterone is essential for the development and maintenance of the uterine lining.
(iii) Progesterone helps prevent uterine contractions ensuring the stability of the pregnancy.
(iv) Progesterone stimulates mammary gland development.
(v) Progesterone suppresses the immune response.
(vi) Progesterone affects metabolism in farm animals by promoting the utilization of fat as an energy source.
(vii) Progesterone helps regulate blood glucose levels and maintain overall metabolic balance.
(1d)

(i) Nesting behavior
(ii) Restlessness
(iii) Swollen udder
(iv) Vulvar swelling
(v) Milk production
(vi) Behavior changes

Livestock management refers to the practice of raising breeding and caring for animals that are raised for agricultural purposes such as food production fiber production or labor.
(2b)
(i) Ear notching: Ear notching is a management practice commonly used in livestock farming, especially in pigs. It involves making unique and permanent cuts or notches on a pig’s ear using special notching pliers. This practice allows farmers to keep track of various aspects such as breeding history health records and ownership making it easier to manage and organize the herd.
(ii) Branding: Branding is a traditional method of marking animals by burning a specific pattern or code onto their skin using a hot branding iron. It is commonly used in livestock farming for cattle and horses. The branding iron is heated in a fire and then pressed onto the animal’s skin leaving a permanent mark.
(2c)
(PICK ANY TWO)
(i) Restraint ensures the safety of both the cow and the person performing the ear notching.
(ii) Restraint allows for greater precision and accuracy during the ear-notching process.
(iii) Restraining the cow can help minimize its stress and anxiety during the procedure.
(iv) Proper restraint can significantly improve the efficiency of the ear-notching process.
(v) Restraint helps prevent complications associated with the cow’s movement during ear notching.
(2d)
(PICK ANY TWO)
(i) The burdizzo crushes and closes off blood vessels simultaneously during castration leading to reduced bleeding compared to using a scalpel.
(ii) The use of a burdizzo eliminates the need for an incision or an open wound reducing the risk of infection compared to using a scalpel.
(iii) The burdizzo is a one-time purchase while using a scalpel requires regular blade replacements and sterilization.
(iv) The burdizzo causes less pain and stress to the animal compared to using a scalpel.
(v) The use of a burdizzo is a quicker and simpler technique compared to using a scalpel.

Animal improvement refers to the process of selectively breeding animals to enhance desirable traits such as productivity health temperament and appearance.
(4b)
(PICK ANY TWO)
(i) Animal improvement aims to increase the productivity of animals by improving their genetic potential for traits.
(ii) Animal improvement focuses on developing animals that have greater resistance to diseases and parasites.
(iii) Animal improvement aims to develop animals with improved fertility rates and reproductive efficiency.
(iv) Animal improvement programs strive to produce animals with desirable quality traits.
(v) Animal improvement aims to develop animals that perform well in different climates and resist extreme temperatures.

(i) Selective breeding
(ii) Hybridization
(iii) Genetic modification

(4d)
(PICK ANY TWO)
(i) Artificial insemination allows for the rapid dissemination of superior genetics enabling breeders to effectively produce offspring with highly desirable traits.
(ii) Artificial insemination allows for the use of semen from superior males that might otherwise be geographically limited or unavailable due to various constraints.
(iii) Artificial insemination reduces the risk of transmitting sexually transmitted diseases and other infections between animals during breeding.
(iv) Artificial insemination is more cost-effective compared to natural mating in terms of transportation housing and management of breeding animals.
(v) Artificial insemination allows for the simultaneous use of semen from a single male on multiple females.
