<jats:p>Milk yield and milk chemical composition are largely affected by the quality
of dairy cattle diet. The chemical composition of milk is dependent upon a
large number of factors, including breed, diet, care, housing system, stage
of lactation, etc. Milk composition is primarily a breed-specific trait. This
study was conducted over a period of 15 months, involving Serbian Spotted
dairy cattle. The experimental animals were assigned to three groups, each
receiving different levels of supplemental zeolite. The control group
comprised cows that received no zeolite supplement. Experimental Groups I and
II were fed compound feeds supplemented with 4% and 2% zeolite, respectively.
Milk samples were analysed for the contents of milk fat, proteins, fat-free
solids and lactose, and density. The results obtained suggest that zeolite
supplementation affects milk chemical composition, depending on the zeolite
level present in livestock feed.</jats:p>
