Response of Slow-Growing Pigs to Antibiotic Supplementation

As pigs approach market weight, the range in weight within a pen often increases with the slow grower lagging further and further behind. These slow growers represent a management problem for producers because they occupy expensive pen space and continue to consume feed for body maintenance needs even though they may not be growing. The objective of the study reported herein was to determine if pigs identified as slow growers during ·the growing period would respond to high levels of dietary antibiotics during the finishing period
