Intensive production systems require that inputs and facilities be used in the most efficient manner. Stocking strategy can have a significant effect on the output from pig units. Crowding can result in depressed pig performance while understocking can cause reduced pigmeat output. Alternatively, split-marketing pigs on a number of days (SM) can result in lower within pen variation in pig weight and improved growth rate of pigs remaining behind. Two experiments were conducted to determine if performance of pigs and pigmeat output per unit area could be improved either by varying the stocking density (by increasing group size) or by engaging in split-marketing.
