PART - A
What is farm service building and explain in brief.
Answer
A farm service building is a specialized structure designed to support the operational and maintenance activities of a farm, distinct from residential or livestock housing. These buildings are primarily used for the storage, repair, and maintenance of farm machinery, tools, and equipment, as well as for processing or storing farm inputs like seeds and fertilizers. They serve as the central hub for mechanical operations, ensuring that essential agricultural implements are protected from environmental damage and are readily accessible for field work.
How directly affect the temperature on livestock production.
Answer
Temperature directly influences livestock production by affecting their metabolic rate, feed intake, and physiological homeostasis. When environmental temperatures exceed the animal's thermoneutral zone, heat stress occurs, leading to reduced appetite and lower energy intake, which directly suppresses growth rates, milk production, and reproductive efficiency. Conversely, extreme cold forces animals to divert energy from production (meat or milk) toward thermogenesis to maintain body temperature, thereby increasing maintenance requirements and reducing overall productivity.
