Poster Information
Abstract: Whey can be fed to animals in different forms such as: liquid whey, condensed whey, or dried whey. In Egypt, whey drying, concentration or fractionation are too costly. Mainly, two types of whey are produced in the Egyptian dairy factories : sweet and permeate whey resulting from hard and white cheese , respectively.Whey products for calves and kids:
Whey can be used as a milk replacer for the young animals, promoting optimal performance and health .Sweet whey as water for lactating cattle : liquid whey should be offered gradually; at the onset 20% whey and 80% water; then whey should be increased by 20% every 3 days

whey as a water is conditioned by:
Whey pH at farm gate must be 5.5-6
Whey pH is not allowed to drop below 4-4.5
Drinking basins should be corrosion resistant
Total coliform counts must not exceed 30/100ml
Roughage must be fed pre whey drinking
Whey must not be introduced over a few weeks
