Introduction
• Background: This is one of the studies under Objective 2 of the project, characterizing pig producers selling in different priced markets.
• Purpose: Exploring the drivers of producers’ choice with respect to breed and feed.
• Approach: Empirical, incorporating simple statistics and econometric analysis (discrete choice frameworks)
• Data: Survey of 1051 households in six provinces of Phu Tho, Ha Tay, Nghe An, Daklak, Dong Nai and Tien Giang, of which 700 are producers.
Hypotheses on the choice of breed and feed
• Breed choice is influenced by:– Demographic, geographic and human capital characteristics– Agricultural land and assets owned and income– Access to suppliers/markets and services– Production system and scale of production
• Feed choice is influenced by:– Demographic, geographic and human capital characteristics– Agricultural land and assets owned and income– Access to suppliers/markets and services– Production system and scale of production– The choice of breed (local, exotic or cross-improved)
Methodology: Simulating households’ decision-making process: A two-stage
procedure
• Stage 1: Raising pigs or not? Characterizing producers vs. non-producers– Assumed to depends on households’ demographic,
geographic and human capital characteristics and possession of resources.
– Modeled as a dichotomous choice problem in a probit framework.
• Stage 2: Which breed and feed system to adopt?– The choice of local breed is modeled as a binary
choice problem in a logit framework.– The choice of feed is modeled as a multiple choice
problem in a multinomial logit framework.

Implications (1)
• Higher-yielding technologies (e.g. improved breed & feed):– Associated with larger scale of production.– Probably beyond the reach of poorer, smaller-scale producers.
• There are still potential market opportunities for smallholder producers: e.g. local breed piglet production
• The shift to higher-value market chains ultimately require:– Changes in the choice of breed toward improved, higher-yielding
genotypes.– Changes in the choice of feed used to optimize the potential of
higher-yielding breeds.– Reduce transition cost of accessing these critical inputs and
extension and other services
Implications (2): Intervention Strategy
• General guidelines:– Must be context specific.– Enhancing access to appropriate inputs and services as
required by specific production conditions.
• Immediate focus:– Must be targeted two types of pig producers.– Easing the transition of smallholder producers to the
state where they are able to effectively engage in modern supply chains of pork.
– Ensuring producers at the lower end of small-scale spectrum of opportunities to embark on modernization pathway or seek for other livelihood options.
