EVALUATION OF RICE BASED DRY DISTILLERS GRAINS WITH SOLUBLE AND ITS IMPACT ON EGG CHOLESTEROL, SENSORY ATTRIBUTES, SERUM BIOCHEMICAL AND HEMATOLOGICAL PROFILE IN LAYING HENS.

A biological experiment was undertaken with (4x2) factorial CRD in 26 wk old CARI Sonali layers (n=120) assigned to eight treatments (i.e. 2 control + 6 test diets) having 15 replicates with one layer in each replicate for ten weeks (26th-35th week of age). Eight experimental diets (D1 to D8) were prepared by incorporating rice dry distiller grain with soluble (DDGS) without and with enzyme at 0, 5, 7.5 and 10% level. Weighed amount of respective diet was offered to individual birds daily. All diets had been kept isocaloric and isonitrogenous in nature. Findings through experiment I revealed that rice DDGS employed in this study contained CP 45.0% which is almost at par of fish meal protein and slightly lower to SBM. However, the gross energy is higher than FM and SBM but lower than maize. In vitro pepsin-pancreatin digestibility and available carbohydrate contents (ACHO) of rice DDGS was found 78.05 and 23.25% respectively. Phytate phosphorus content in rice DDGS was 0.44%. However non-phytate phosphorus was 0.33% which is 57.14% of total phosphorus. Different levels of rice DDGS either sole or in combination with enzyme did not have any significant (P>0.05) effect on egg cholesterol, sensory attributes except appearance and colour of boiled egg, however significantly (P<0.01) increased the haematological, serum protein profile and have lowering effect on serum lipid profile, which was found better effect after dietary addition of enzyme during II experiment.
