Sow lactation performance is critical to piglet survival and pre-weaning growth. Effective lactogenesis combined with strong piglet vigour at birth will help prevent hypoglycaemia and mortality. In addition, immune protection of the sucking pig is dependant on the acquisition of immunoglobulins from the colostrum of the sow. High milk output in late lactation will ensure greater weaning weights, since piglet growth potential exceeds milk supply by day 10 of lactation (Harrell et al, 1993). Maximising sow feed intake ensures maximum milk production. A variety of plant extracts are recognised for their health and growth promoting properties which include stimulation of the digestive and immune systems (Platel and Srinvansan, 1996). The objective of this study was to evaluate the ability of various plant extracts to stimulate piglet and sow performance when used as supplements in the diets of lactating sows. Three extracts were selected for their potential benefits to health, appetite and digestion, these being Yucca Shidigera, Quillaja Saponaria and Combination (a blend of the spices capsicum 1.0%, cinnamaldehyde 1.25 % and oregano oil 0.85 %).
