Animal Agriculture in the Developing World Jake Hooper
Overview of Animal Agriculture
Uses of livestock
Large ruminants are kept for work
Meat and milk are by-products
Kept primarily for meat and milk is a by-product
Crop residues are the main source of feeds
Problem: not enough for a year-round supply
In Africa, grasslands are heavily grazed to feed livestock
Problem: over-grazing has damaged the grasslands
Adding back to Agriculture and Society
Waste from livestock:
Returns nutrients to soil
Cheap source of fertilizer
More, higher yielding crops
More food for people and feed for livestock
Sustaining Animal Agriculture
Difficult to sustain because of:
High grain prices
Combat animal illness (costly)
Veterinarians (many animals to only a few vets)
Correct animals in their optimum environment
High grain prices competing with fuel production
Land, feed, animals, equipment
Breeding programs, efficient animals
Education is a MUST!!
Correct feeding strategies
Special attention to economics
