Methods used by Ute Lemke, [smallholder]
1. Evaluation of smallholder pig production systems in North Vietnam
1.1 Pig production management and pig performances
1.1.1 structured household interviews
1.1.2 recording of pig live weights (EziWeigh weighing system, Tru-Test, New Zealand)
- socio-economic characterisitcs of households
- pig production and management: pig keeping, breeding, additional weaner - fattener production, housing, veterinary service
- pig performance: reproduction, growth, live weight output
1.2 Assessment of input, output, economic and biological efficiency
1.2.1 structured household interviews
1.2.2 recording of pig live weights (EziWeigh weighing system, Tru-Test, New Zealand)
- socio-economic characterisitcs of households
- pig production management
- Inputs into pig production/variable cash costs: feed costs, purchase of weaners for fattening, mating costs, veterinary costs
- offtake from pig production
- feed use efficiency
- economic benefit and efficiency
2. Pig production systems as part of smallholder livestock production systems in mountainous areas of North Vietnam – comp
2.1 structured household interviews
2.2 Rapid Rural Appraisal (RRA) tools
- resource flow in small-scale agricultural production system
- socio-economic conditions of farm households
- smallholder livestock keeping: herd sizes, utilisation of livestock species
- input into livestock/feed resources: ruminants, pigs, poultry, fish, utilisation of limited feed resources (maize, rice)
- input into livestock/monetary resources: feed costs, veterinary expenses, purchase of animals
- output from livestock: cash revenue, consumption of animal products, draught, manure
- comparative evaluation of different livestock production enterprises
3. Dynamics and developmental trends of smallholder pig production systems in North Vietnam
3.1 structured household interviews

- socio-economic characteristics of investigated pig keepers
- current pig production management
- development of smallholder pig production until today
- future development of smallholder pig production
roduction, housing, veterinary service, feeding, offtake
ening, mating costs, veterinary costs
inous areas of North Vietnam – competition for household resources
