Evaluation of Goat Milk Containing Galactooligosaccharides After Supplementing the Ration with Amino Acids

Mervat I. Foda, S.M. Kholif and A.M. Kholif
The aim of this study was to evaluate the effect of supplementing goat’s ration with different forms of lysine and methionine on milk production, its chemical composition and consumer’s acceptability. To maximize goat milk benefits, different concentration of β-D-galactosidase were used to form galacto-oligosaccharides after supplementing the ration with lysine and methionine in protected and unprotected forms. Milk acceptability and its chemical composition were evaluated compared to control samples. The results showed that milk fat, lactose, total protein and milk yield were increased by adding the amino acids in both different forms. Organoleptic evaluation indicated significant increase in taste and overall acceptability of goat milk containing higher concentration of galactooligosaccharides. Also, supplementing goat ration with these amino acids should be recommended to increase milk production and its contents. Formation of galactooligosaccharides in goat milk could be recommended to decrease most of infant’s allergy and diseases.
