Types of Livestock - JSS3 Agricultural Science Past Questions and Answers - page 2

Livestock production plays a vital role in global agriculture and economies by providing food, income, and raw materials. It contributes to human nutrition through protein-rich meat, eggs, and dairy products. Livestock also serve as sources of employment and support various industries, fostering economic development in rural areas.

Sustainable livestock farming practices, such as rotational grazing and agroforestry, promote environmental conservation by enhancing soil health, biodiversity, and water retention. These practices reduce the environmental footprint of livestock operations, mitigate greenhouse gas emissions, and prevent soil erosion. Additionally, efficient feed management minimises resource waste and pollution.

Domesticated livestock yield a range of products essential for human consumption and industrial use. These include meat from cattle, sheep, goats, and pigs, which serve as significant protein sources. Additionally, dairy products such as milk, cheese, and yoghurt contribute essential nutrients like calcium and vitamins. Other products include wool from sheep, eggs from poultry, and honey from bees.

Integrated crop management (ICM) employs holistic approaches to enhance agricultural sustainability by combining various practices. These include crop rotation to prevent pest and disease buildup, precision farming for efficient resource use, and soil health management for improved fertility.

Ethical considerations in livestock farming encompass animal welfare, proper handling, veterinary care, and ethical sourcing. Adhering to animal welfare standards ensures humane treatment throughout the animals' lives, from housing to transportation and slaughter.
