Abstract
A study has been carried out to find out the chemical composition and in vitro fermentation characteristic of dried distillers grain soluble (DDGs). Six DDGs feeds samples were collected from different parts (feed mills) of Namakkal district. The samples were ground to pass through a 2-mm screen and then analysed for chemical analysis and in vitro dry matter digestibility. In the present study the Crude protein, Crude fibre, Ether extract, Total ash, Sand and silica content of DDGs are 47.95, 1.12, 1.19, 4.77 and 0.058% respectively. The calcium, phosphorous, magnesium and potassium content of DDGs were 0.16 %, 0.63%, 0.31% and 0.98% respectively. Similarly the trace mineral like zinc, copper and manganese are 23 ppm, 7.4 ppm and 26 ppm respectively. The traces of aflotoxinB1 (0.5 ppb) also noticed in the DDGs samples. In vitro DM digestibility of DDGs at 24 and 48 hrs was 38 and 42 % respectively. Hence, the present study showed that DDGs had relatively high protein content and in vitro DMD and thus have the potential to be good alternate feed source for livestock.
