Abstract:
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.
