| Abstract |
This study was conducted to incorporate soap-stock as non-traditional fat in ruminant rations as source of energy in instead of part of corn. One level used of palm oil soap-stock (PL-SS) and sunflower oil soap-stock (SF-SS) with replacement of yellow corn grain (5% of total DM whole ration). Nine Ossimi male rams were divided randomly into 3 groups and randomly allotted to 3 experimental rations as following; control, PL-SS and SF-SS. Average daily DM intake and nutritive values as TDN, DE and DCP intake decreased with added both source of sop-stock. The values of pH in the rumen liquor increased (P<0.05) with adding soap-stock compared to the control diets (6.74 vs. 6.92 and 6.99 for PL-SS and SF-SS, respectively). The overall mean of TVFA’s values decreased with added fat. The concentration of FFA’s in the rumen liquor was increased with added fat compared with the control diet.
Added either PL-SS or SF-SS increased TL, TG, total cholesterol and FFA’s concentration. Total protein concentration and globulin blood serum were increased with adding either PL-SS or SF-SS compared with control diet, however, albumin values and A/G ratio were not affected with added fat. Both sources of added fat increased alkaline phosphates in serum, however, no effect were noticed on SGPT and SGOT.
DM digestibility coefficients were insignificantly decreased with added fat compared with the control diet. Digestibilities of OM, CP and CF decreased with added SF-SS compared with control and PL-SS, except CP digestibility was decreased with added PL-SS. Feeding PL-SS and SF-SS significantly reduced NDF, ADF and cellulose digestibility coefficient, however, it was no significant effect within sources of fat, except hemi-cellulose with added SF-SS decreased.
Lipids digestibility as AEE, EE and TFA’s were significantly higher with feeding tow sources of fat compared with control diet. The digestion coefficient of EE was less than that of the digestion coefficient of AEE and TFA’s. the values of DE decreased with added fat compared with control diet. Values of DCP were lower significantly with added both source of sop-stock compared with control, and also, significant difference was found between tow sources of soap-stock. Although, lowest values of nitrogen digestibility with added fat, the total nitrogen excretion and nitrogen balance were increased significantly compared with control diet.
In conclusion, the results of this study illustrate that, palm oil soap-stock can be used as a safe non –traditional source of energy in ruminant diets. Supplemented PL-SS could be included up to 5% of the whole ration for sheep.
