Numerous physical, biological and socio-economic factors interact to influence the nature and extent of animal agriculture practiced in any region. Climate, which includes both temperature and precipitation, can affect any animals’ ability to survive and to be productive in many ways.

What is the main reason for growth in animals?

Animal growth is determined by a complex variety of factors but these can be reduced to three main categories: the animal’s gene pool, the nutrients with which it is supplied, and its environment. The common factor linking and communicating these is the endocrine system.

How does growth happen?

The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis. … Hence, a cycle consisting of cell growth and cell division is established.

What are hereditary factors?

Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents. … The study of heredity in biology is genetics.

How different animals grow and develop?

The primary way that animals grow and develop is by building more cells. When an animal eats food, its body breaks the food down and uses it to fuel its energy requirements and build new cells through the process of mitosis. … To produce more cells, animal cells divide in two.

What factors contribute to the way organisms grow and develop?

Organisms have unique and diverse life cycles. Animals engage in behaviors that increase the odds of reproduction. An organism’s growth is affected by both genetic and environmental factors. Growth and division of cells in organisms occurs by mitosis and differentiation for specific cell types.

What are the five factors that influence growth and development?

Five main factors identified in contributing to growth and developments at early childhood are nutrition, parent’s behaviours, parenting, social and cultural practices, and environment.

How do biological factors influence development?

Biological factors include genetic influences, brain chemistry, hormone levels, nutrition, and gender. Here is a closer look at nutrition and gender and how they affect development.

How do animals use matter for growth?

Growth and repair of body parts requires matter, which for animals are raw materials. When food is eaten, matter is broken down into simpler forms. These can be used to build or repair an animal’s body. Growth, repair, and other life processes also require energy.

How do genetic factors affect animal growth?

The growth and development of meat animals are largely affected by two important factors. The firs one is genetic factors, which it includes disease resistance, feed conversion efficiency, breed, and abnormal growth rates. … In plant feed animals, environmental factors influence the availability of nutrients.

How do genetic factors influence growth?
