Sugar beet tops including leaves and crown harvested and chopped into 3-6 cm, mixed with sugar cane pulp and sugar cane molasses （about 5% of the total mass） to provide a mixture contained 30-35 percent dry mater. After two months of ensiling, the silage was evaluated and used in the ration of lactating buffaloes. A Latin square experiment in a changeover design, with three periods of time, each with 20 days for adaptation and 10 days for recording data, was conducted in which 15 multiparous lactating buffloes were used in three similar groups, each with five animals. The prepared silage was included in the diet of lactating buffaloes where a control diet （A） was compared with treatment diets contained 25% （B） and 50% （C） silage （DM basis） respectively. Milk yield was recorded, sampled and analysed for fat, protein, solid not-fat and total solids-content. The maximum daily rough milk yield per animal was obtained on diet C while minimum on diet A （P 〈 0.05）. Similar trends were observed for 4% fat corrected milk, and 3.5% fat corrected milk that were significantly different between the treatments （P 〈 0.05）. The percentage of crude fat and daily fat yield per animal were significantly （P 〈 0.05） higher in treatment C comparing to A and B. An increasingly trend of milk and fat yield was observed when the animals received silage contained diets but statistically it was significant only for the diets contained 50% silage. In addition, the fat percentage was significantly （P 〈 0.05） increased when the buffaloes received diet containing 50% silage. The highest （P 〈 0.05） amount of protein and total solid yield obtained, when the animals received high （50%） silage diet.
