Solution
(a) Ways in which water is important to farm animals
•It aids digestion of feed.
•It promotes metabolic activities in the body.
•Involved in the formation of products like milk, egg and meat.
•To satisfy thirst/prevent dehydration.
•Helps in regulating temperature.
•Aids in excreting waste products.
•It is source of lubricant.
•Helps to maintain turgidity of body cells.
• It is involved in secretion of hormones and semen.
•Transport nutrients to body tissues.
(b) Activities involved in artificial insemination
•Sterilization of equipment.
•Select proven bull for semen collection.
• Collect semen
• Screen semen for quality.
•Dilute semen.
• Cool to low temperature/cool to appropriate temperature/freezing of semen.
•Storage of semen.
•Restrain the animal
•Introduction/ deposition of screen.
•Thawing.
•Selection of female animals on heat.
(c) Factors that predispose farm animals to diseases.
Poor nutrition / poor feeding: When animals are not properly fed with adequate and balanced ration, they become predisposed and susceptible to diseases. When animals, however, are fed with good and balance diets, their immune systems is strengthened and are not easily exposed to the attack by disease pathogens.
Poor sanitation / poor hygiene condition: The sanitary or hygienic conditions prevailing in the pens and the environment of farm animals greatly influence how animals become susceptible to diseases attack. When animals are exposed to poor environmental conditions (poor hygiene and poor sanitation conditions), they become easily predisposed to diseases. The opposite is true.
Physiological injury/ wounds: When farm animals are injured or have wounds on their skin, it becomes a source entry point to disease pathogens. Thus, when animals become injured they become predisposed to diseases.
Chemical poison: When farm animals are exposed to chemical poisonings, they become easily exposed to diseases. When animals take in poisons, their immune system breakdown and they become easily predisposed to diseases.
Poor housing / overcrowding/ poor ventilation: When animals are exposed to poor housing, overcrowding and poor ventilation conditions, they become easily predisposed to diseases. Such poor housing, overcrowding and poor ventilation create stress to conditions and the animals become susceptible to diseases pathogen attack.
Environmental factors / harsh/unfavourable climatic conditions: Environmental and climatic conditions greatly affects the health status of farm animals. When the environmental conditions are harsh and unfavourable, farm animals become easily predisposed to disease pathogen attack.
Hereditary / genetic condition / breed type: The hereditary, genetic condition, and breed type of farm animals greatly affect their health status. Some animals due to their genetic make-up are easily predisposed to diseases. Some animals are generally hardy others are very susceptible to diseases due to their genetic composition.
Hormonal imbalance: Any imbalances in the hormone secretion of farm animals can easily predispose them to diseases. Insufficient and inadequate secretion of particular hormones usually results in the animals becoming easily susceptible to diseases.
Age: As animals are ageing, they become more predisposed to various disease pathogens. The immune system of farm animals tends to decline sharply with age. Older farm animals are easily predisposed to diseases than younger animals.
Sex: Some diseases are sex linked. Hence some diseases easily attack one particular sex or the other. For example, mastitis- a disease of the udder is very common among the female animals than the male animals.
