Abstract

Forage diversity in the grazing diet of ruminants is an area of growing interest as it could provide key nutritional benefits in animal production. The objective of this study was to determine if there is a positive correlation between the presence of a wide range of chemically rich forages and the health of growing goats. This idea was assessed by comparing physiological responses to vaccination challenges of animals fed differing diets. In two separate trials, goats were placed in individual pens and fed one of three treatments in a completely randomized design. Treatments in Trial 1 consisted of redberry juniper and shin oak. In Trial 2, goats were fed totally mixed rations containing grape and blueberry pomace at an inclusion rate of 20%. Average daily gain, intake, and blood chemistries were assessed following a vaccination health challenge. In Trial 1, goats fed shinoak had higher (P<0.05) globulins and total protein of blood serum. Trial 2 revealed no differences in ADG, intake, or blood parameters evaluated. In conclusion, phytochemical compounds may have the ability to enhance the health of goats, but the health effects may be dependent upon the source and structure of the chemical components offered.
