3. Livestock Production to 2050:
TRENDS
GLOBAL TRENDS: The Livestock
Revolution
• Livestock demand and
production are increasing rapidly
in developing countries, and will
continue to rise (with some
differences for commodities)
• Global per capita consumption
2% in meat, 61% milk,
• 2000 less consumption of ASF in
Africa than EC, but in 2050 this
will be reversed

6. Projections of livestock production increases at global
level: 2000–2050
In half a century, total livestock
commodity production is
projected to increase by 92%:
+ 106% for monogastric meat
(pig and poultry) and poultry
eggs
+ 88% for ruminant meat (cow,
sheep, goat, camel, water
buffalo)
+ 85% for milk
With large regional differences

10. Trajectories of growth for the livestock sector
Strong growth
Intensifying and making
increasingly market
oriented, often
transforming smallholder
systems
Fragile growth
Where remoteness,
marginal land resources or
agro climatic vulnerability
restricts intensification
High growth
with externalities
Intensified livestock
systems with diverse
challenges, including
the environment and
human health

12. Constraints in smallholder pig production systems
in Sub-Saharan Africa
Feeds and feeding (Seasonality, poor
quality of feeds)
Disease control measurements (parasites,
viral & bacterial infections)
Genetics & breeding (Inbreeding, poor
quality animals)
Husbandry and management (deficient
corrals, if available)
Poor management of excreta (pollution,
could lead to social conflicts)
Human and Cultural Capitals
Pezo and Waiswa, 2012
13. Constraints in smallholder pig production systems
in Sub-Saharan Africa
Technology transfer bias (mostly focused on
males, although women manage the pigs)
Limited knowledge on new options for
improving productivity and profit
Poor access to information services
(technology, markets)
Absence of organizational strategies to achieve
economies of scale
Sector largely ignored by policy makers
Limited access to credit
Social & Financial Capitals

21. How to incorporate forage crops in smallholder
pig systems in Uganda?
Planting forages – Limited land
(Rural: 1.4 – 3.3 acres; Urban: 1.4 – 1.8 acres;
most don’t have area dedicated to forages)
Forages have to be inter-cropped or
as hedgerows
For what group of animals?
• Breeding stock, less for growers, &
fatteners
• NOT for piglets and weaners (limited
intake and fiber digestion capacity)
Which forages should we focus?
Those with at least similar quality than the
crop residues commonly used. Those able to
produce when crop residues are not available.

D. velutinum, F. macrophylla, Cannavalia brasiliensis,
Centrosema brasilianum, S. guyanensis (Heinritz et al., 2012)
25. Nutritional limitations while using forages for pigs
High fiber content, limits voluntary intake
Low energy density, along with limited gut capacity
does not allow pigs to cover energy requirements
Requirement of essential amino acids by pigs
Presence of toxic or inhibitory factors
Lectins in soybean and Amaranthus cruentus
Tannins in several legumes (herbaceous and shrubs)
Saponins in B. brizantha, B. decumbens, Amaranthus
hypochondriacus
Phytates and oxalates in S. sphacelata, Vigna unguiculata,
Lablab purpureus.
