Figure 1From: Practical starter pig amino acid requirements in relation to immunity, gut health and growth performanceThe effects of immune system activation and diet complexity on average daily gain. Dietary treatments include feeding a complex starter diet, a medium complexity diet, and a low complexity diet. Immune activation includes control pigs fed ad libitum, LPS injected pigs fed ad libitum, and control pigs pair-fed to that of the LPS challenged pigs. Main effects of diet complexity and immune system activation are significant (P < 0.01). There was no immune system by diet complexity interactions (Adapted from Dritz et al., 1996 [4]).Back to article page
