Abstract: | This study evaluates smallholder pig production systems in North Vietnam, comparing a semi-intensive system near a town with
good market access, where a Vietnamese improved breed has replaced the indigenous pig breed, and an extensive system away
from town, where the indigenous breed still prevails. Fieldwork was conducted in 64 households in four villages. Repeated
farm visits yielded 234 structured interviews. Data were analysed by linear models and non-parametric tests. Production inputs
and outputs were quantified, and feed use efficiency and economic efficiency were assessed. The gross margin was higher for
semi-intensive production with the improved breed, while the benefit–cost ratio was higher under extensive conditions with
the indigenous breed. The net benefit did not differ between systems. Twenty-four per cent of farmers yielded a negative net
benefit. In one village under extensive conditions, live weight output from indigenous sows with crossbred offspring compared
positively with the output from semi-intensive production with improved genotypes, but was associated with high inputs, making
production inefficient. Results indicate that improved genotypes might not be an efficient production alternative for saving-oriented
production with limited resource supply. Suitability of evaluation parameters, farmers’ production aims, and factors impacting
the production success in different systems are discussed. |
