Opportunity Revenue and the Cost of Intervention

Causes of variation in pig production are many and not well understood. One of the key issues arises from the spread in pig weights which begins through a kind of competitive process among the pigs beginning well before birth. Competition in the uterus and during lactation results in a sometimes widely spread distribution of potential in pigs by the time they reach weaning. Some common management procedures are implemented beginning at birth to attempt to reduce variation but their outcome is often marginal, while others, such as processing and castration introduce new challenges to subsets of pigs. Pigs of different weights require different environmental temperatures, feed types and other conditions, yet as variation increases, "average" conditions are provided which probably miss the ideal environment for all but a very small number of pigs.

Some producers are experimenting with simply euthanizing the smallest pigs either at weaning or prior to weaning. An arbitrary percentage is chosen, such as the smallest 3-5% as candidates for euthanizing. Recently published trials (Wolff, Lehe, Keffaber and Deen, "A Producer's Tool for Measuring Attrition", IPVS, 2006) suggest that the weight of the pig, relative to its cohort at both weaning and the end of nursery phase are sentinel indicators of eventual final quality with the weight at the end of the nursery phase a stronger predictor. The result was obtained with all other things held constant so it isn’t clear if targeted or more intensive individual interventions aimed at the smallest pigs at weaning and feeder pig stages would affect the outcome.
