Abstract
of part ictlly cmbst itut ing milk proto inc; by plant proteins in C8.ll
milk replacc:;rs. ·The IJlanL p:cotein :::-~ource>5 used were ;
a) Locally produced soybean meal (ESP) •
b) Imported soybean flour (ASP).
c) Corn glutine (GP) •
Anim<~ls were bought from locel markets and transferert to +:he
experimental i’arm station of Faculty of Agriculture Ain Shams Univ.
at Shoubra :<;1-Kheima, Cairo , Ee;ypt •
Milk replacGrs --,ere offered in buckets twice daily. A calf stA.rter
