Abstract
In a 90-day growth trial, 18 Murrah buffalo bull calves were randomly
allotted to three dietary treatments (T1 to T3) comprising of Super Napier green
fodder and concentrate mixture containing RDDGS at 0 (T1), 15 (T2) and 30
(T3) percent levels to meet the nutrient requirements (ICAR, 2013). All the
three diets were evaluated for their effect on growth, nutrient utilization, serum
biochemical profile in buffalo bull calves.
The per cent DM, OM, CP, EE, CF, NFE, TA, NDF, ADF, hemi
cellulose, cellulose, ADL, and silica of RDDGS were 94.08, 93.97, 48.33,
5.15, 4.91, 38.18, 6.03, 41.29, 21.12, 20.17, 8.01 and 4.87, respectively. The
percent calcium and phosphorous content of RDDGS were 0.96 and 1.37,
respectively. The study indicated that feeding diets containing RDDGS up to
30% level in the concentrate mixture had no effect (P>0.05) on body weight
gains, ADG, feed conversion ratio in buffalo bull calves as compared to the
control. The cost of feed / kg gain decreased (P<0.05) by 6.61 and 7.18 in
T2 and T3, respectively as compared to T1.
Feeding diets containing RDDGS up to 30% level in the concentrate
mixture had no effect (P>0.05) on DM, OM, CP, EE, CF, NFE, NDF, ADF,
cellulose and hemi-cellulose digestibility as compared to the control. The
average DMI of buffalo bull calves expressed as kg/d or as % body weight was
similar among the treatments. Inclusion of RDDGS up to 30% level in the
concentrate mixture had no effect (P>0.05) on DCP and TDN contents
expressed either as intake (kg/d) or as % in the diet consumed. The DM, DCP
and TDN intakes expressed as g/kg W075 and ME intake (M Cal / kg W075)
were similar among all the treatments and were higher than the values
recommended by ICAR (2013) standards.
The study revealed that feeding diets containing RDDGS at 15 and 30%
level replacing soybean and gingelly cake at 50 and 100% level in the
concentrate mixture had no effect (P>0.05) on serum biochemical profile in
buffalo bull calves as compared to the control. Thus, it can be concluded that
RDDGS can be included up to 30% level replacing conventional protein
supplements up to 100% level in the concentrate mixture for feeding buffalo
bull calves to decrease the cost of feeding without any adverse effects.
