Improving dairy production in Tanzania
Most milk in Tanzania is produced by cattle in low input, low yielding systems. Dairy production & household income can be increased by using higher yielding breeds and feeding better quality diets.
Here we use production systems from Mbeya as an example of how milk yields and income from dairy production can be improved in the southern highlands of Tanzania.
Current production systems in Mbeya
Most milk in the southern highlands is produced in intensive smallholder production systems. These systems are based on cut and carry of native grasses and crop residues with minimal grazing. Crossbred and improved cattle breeds are common, and milk is sold into formal value chains.
Issues limiting milk production
Animal genetics
Local cattle breeds have low milk yields.
Feed shortages & costs
Seasonal feed shortages. Decreased land area available for grazing. Cost & quality of concentrate feeds is variable.
High animal mortality & low reproduction rates
Largely caused by disease & poor nutrition.
Modelled baseline household
- 6 Tanzania Shorthorn Zebu cows (local cattle)
- Cows fed native grass + home-grown crop residues in a cut & carry system
Modelled interventions to increase production
Improved genetics
Local cattle replaced with Friesian cross cattle.
High quality forage
Cows supplemented with high quality, home-grown legume forage.
Supplementation with concentrate
Cows supplemented with purchased concentrates:
- Low concentrate: 3 kg maize bran/cow.day
- High concentrate: 5 kg maize bran + 1 kg cottonseed cake/cow.day
Combined interventions
Improved genetics + provision of high quality forage & concentrate.
Interventions can increase production and profitability

Key messages
Modelling of interventions for dairy systems in the Mbeya region shows the greatest increases in production come from combining multiple interventions.
Improved breeds such as Friesian cattle have higher genetic potential but are bigger and have higher nutrition and health care requirements compared to local cattle.
The biggest increases in household income are associated with high individual milk yields combined with improved reproduction and lower mortality rates, resulting in more cows lactating each year and more offspring available for sale.
Combined interventions are more successful than single interventions.
The highest milk yields are achieved when higher yielding cattle breeds are fed high quality diets, particularly concentrate feeds.
