Abstract

Chemical composition of milk as affected by using vegetables and
fruits market waste (VFMW) in feeding cows was examined over a period of
12 weeks. The use of VFMW in a silage in (Treatment I) to replace 15% of
the control ration (Ammonia-treated rice straw and concentrate) resulted in an
increase in fat, lactose, protein, casein and whey protein content of milk. Non-
protein N and non-casein N were lower. In treatment (II), VMW and EI-
Mufeed was used to replace 15% of the control ration, whereas in treatment
(III), VMW and ground yellow corn was used to replace 5% of the control
ration. Results showed that treatment (II) gave the highest fat and lactose
content followed by treatment (I), whereas treatment (I) gave the highest
protein and casein content followed by treatment (II). In all cases, the control
milk samples had the lowest values of fat, protein, casein and whey protein
content.
