Abstract
Since decoupling of the CAP, many Scottish suckler cow farms are facing financial
difficulties. In response, many farmers are out-wintering extensively managed suckler
cows to minimise production costs. These systems are of animal welfare concern. A
range of trade-offs between animal welfare indicators and between animal welfare and
farm profitability can be identified. A Dynamic Programming (DP) model was
developed to study these trade-offs. Two herds were modelled assuming their feeding
regimes were either low (LHERD) or high (HHERD). The objective of the DP was to
maximise the expected net margin from a current cow and its successors over an
infinite time horizon. Preliminary results showed that the rate of voluntary culling was
higher in HHERD than in LHERD. Animals in HHERD had shorter life expectancy.
The expected net present value was 58% lower in LHERD than HHERD (-£41.5 and -
£24.3 respectively). These results suggest a heavier culling rate and shorter longevity
for animals in HHERD that compromises animal welfare. Also HHERD had a greater
implied stocking density than LHERD. This increase of the cows’ population may
adversely affect the environment. The presented model provides some of the basic
information required to explore some of the trade-offs between farm profit, animal
welfare and the environment.
