3. LIVESTOCK NUTRITION
3.1. Nutrient Requirements for Different Species
Livestock species differ in their nutrient needs based on their digestive systems, production purposes, and physiology.
1. Cattle
Nutrient |
Requirement |
Notes |
Energy |
High, especially for lactating or growing animals |
From carbohydrates and fats |
Protein |
Moderate to high (10-20%) |
Important for growth, milk production |
Fiber |
High (minimum 18% in diet) |
Essential for rumen function |
Minerals & Vitamins |
Balanced calcium, phosphorus, magnesium |
Vital for bone development and metabolism |
Water |
30-50 liters/day |
Depends on climate, feed, production level |
2. Sheep
Nutrient |
Requirement |
Notes |
Energy |
Moderate |
Depends on growth, pregnancy, lactation |
Protein |
8-16% |
Higher during pregnancy and lactation |
Fiber |
High |
Essential for rumen health |
Minerals & Vitamins |
Adequate calcium, phosphorus |
Important for wool production and reproduction |
Water |
4-10 liters/day |
Essential for digestion and metabolism |
3. Goats
Nutrient |
Requirement |
Notes |
Energy |
Moderate to high |
For milk production and growth |
Protein |
10-18% |
Important for reproduction and growth |
Fiber |
High |
Needed for rumen fermentation |
Minerals & Vitamins |
Balanced mineral intake |
Essential for bone and horn growth |
Water |
5-15 liters/day |
Varies with production and environment |
4. Pigs
Nutrient |
Requirement |
Notes |
Energy |
High (mainly carbohydrates) |
Supports fast growth and reproduction |
Protein |
15-22% |
Critical for muscle development |
Fiber |
Low |
Limited fiber tolerated |
Minerals & Vitamins |
Balanced calcium, phosphorus, salt |
Important for bone and overall health |
Water |
4-10 liters/day |
Depends on age and environment |
5. Poultry
Nutrient |
Requirement |
Notes |
Energy |
High (mainly carbohydrates and fats) |
Supports rapid growth and egg production |
Protein |
16-22% |
Critical for feather and muscle development |
Fiber |
Very low |
High fiber reduces digestibility |
Minerals & Vitamins |
Calcium (high for layers), phosphorus |
Essential for eggshell formation and growth |
Water |
0.5-1 liter/day per bird |
Critical for metabolism and egg production |
