Abstract
Protecting dietary vitamin C and high oleic oil from ruminal degradation by formulating these nutrients within a formaldehyde-free feed supplement and its effects on the nutritional profile of goat milk were investigated. Two protein-oil gel supplements (PGS), both containing high oleic sunflower oil (oleic acid source) and ascorbyl palmitate (vitamin C source), one based on casein (C-PGS) and the other based on keratin (K-PGS), were prepared and included in lactating goat diets. Both increased unsaturated fat content in goat milk, but only feeding with C-PGS resulted in a significant increase. K-PGS increased vitamin C in goat blood serum but not in milk. Blood serum vitamin C concentration for protein-oil gel supplement diets and unprotected ascorbyl palmitate diet were similar, so protection of vitamin C was questionable. The two protein-oil gel supplements increased concentration of oleic acid in both blood serum and milk with a corollary decrease in hypercholesteremic fatty acids.
