Discuss the function of hormones in animal growth and hormones control What are the factors affecting animal growth

Hormones are chemical messengers that regulate various physiological processes, including animal growth. Key hormones like growth hormone (GH) stimulate cell division, protein synthesis, and bone growth. Thyroid hormones regulate metabolism, which is crucial for energy availability for growth. Sex hormones (like testosterone and estrogen) influence growth spurts during puberty and the closure of growth plates in bones. Hormone control primarily occurs through negative feedback loops, where the presence of a hormone inhibits its further release, maintaining balance.

Several factors affect animal growth. Nutrition is paramount, as adequate intake of proteins, carbohydrates, fats, vitamins, and minerals provides the building blocks and energy for tissue development. Genetics determines an animal's inherent growth potential, influencing factors like mature size and growth rate. Environmental conditions such as temperature, housing, and space can impact growth by affecting metabolism and stress levels. Disease and parasites divert nutrients and energy away from growth, often leading to stunted development. Lastly, stress (e.g., social hierarchy, handling) can release hormones that inhibit growth.
