Evidently, feeding alone accounts for about 60-70% of the total cost of raising the stock. Decreasing area under grass lands, combined with an increasing diversion of crop residues for fuel and industrial uses, is creating an acute shortage of fodder supply for India’s livestock. Non-availability of quality fodder in sufficient quantities, in the medium to long term, could negatively affect the health of livestock and, consequently, the production of milk, eggs and meat. However, what has occurred over the past several decades is that the abundance and generally favorable pricing of corn and soybean meal have led to a situation in which other ingredients, which may have been widely studied, have been International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 09 (2018) Journal homepage: http://www.ijcmas.com Thirty two (32) no. of 6 to 9 months of age average body weight 88 kg were brought from a private dairy farm and were grouped into four (4 x 4). The treatment groups calf’s diet were formulated on iso-caloric and iso- protein basis with the graded level of inclusion dried rice distillers grains and solubles (DRDGS) @ 0% (TD0), 5% (TD5), 10% (TD10), 15%(TD15) respectively. Both concentrate and roughages were offered as per body weight of calves. Fortnightly feed intake, body weight gain and average daily gain (ADG) were calculated. Feed intake was not significantly (P>0.90) differ among treatment groups but the group receiving 5% DRDGS attained highest body weight and the control group attained the least. The average daily gain (ADG) was not affected by dietary supplementation of DRDGS at graded level. The highest ADG was found in TD5 group lowest in control (TD0) group. Overall, the ADG was numerically differ in various experimental groups but statistically not significant (P>0.07). Again feed intake per unit gain was highest in TD0 group and better was in TD5 group. The TD10 and TD15 group did not show any significant (P>0.05) result. The dry matter, crude protein, crude fiber, N- free extract, neutral detergent fiber and cellulose digestibility was significantly (P<0.05) affected by dietary inclusion of graded level of DRDGS in the ration and values were always in higher side but ether extract and hemi-cellulose digestibility was not statistically significant.
