Abstract

Background and objectives: Degradation in rumen often results in wastage of dietary proteins, particularly in productive ruminants. For this purpose, protection of proteins is essential for productive animals, where the protein requirement of these animals cannot be met from microbial protein synthesis. Therefore, this study was conducted to investigate the effect of Green tea waste extract on ruminal degradability and intestinal digestibility of soybean meal dry matter and Crude protein. Materials and methods: For extraction from Green tea waste, a solvent was prepared with a ratio of 10 ml of methanol, 10 ml of ethanol and 80 ml of distilled water per 100 ml. The soybean meal treated at 0 (control), 5, 10, 15 and 20 percent of dry matter with this extract. Ruminal degradability of dry matter and Crude protein determined using two Taleshi bulls by Nylon bag method in 0, 2, 4, 6, 8, 12, 24 and 48 hours. Intestinal digestibility measured In vitro. Results: Treatment decreased the amount of dry matter (DM) degradability of soybean meal in all incubation times (P<0. 05). Crude protein (CP) degradability of processing treatments by 5% and 10% extract were not different significantly in comparison to control group (P>0. 05) but 15% and 20% extract significantly reduced CP degradability related to control (P<0. 05). Rapidly degraded fraction (a) of DM degradability of soybean meal in treatments processing with 15% and 20% extract, significantly decreased related to control (P < 0. 05). Fraction of CP degradability significantly reduced by processing in all treated group related to control (P<0. 05). Slowly degraded fraction (b) and potential degradability (a+b) of DM in 5%, 10%, 15% and 20% extract treatments significantly decreased related to control (P<0. 05). b fraction of CP degradability in control, 5% and 10% extract treatments had no significant difference, but 15% and 20% level of extract significantly decreased this fraction related to control (P<0. 05). Constant rate of degradability of DM and CP were not different between treatments. Effective degradability of DM and CP (in 2%, 5% and 8% out flow rates) significantly reduced by treatment (P<0. 05). Intestinal digestibility of DM was significantly higher in soybean meal treated with 5 and 10% extract than other treatments, but 20% extract significantly reduced it (P<0. 05). In addition, intestinal digestibility of CP was significantly higher in soybean meal treated with 5% and 10% extract than other treatments, but 20% extract significantly reduced it (P<0. 05). Conclusion: Soybean meal treatment by Green tea waste extract can decrease its ruminal degradability. According to results from DM and CP intestinal digestibility, 5% and 10% levels of Green tea waste extract improved soybean meal intestinal absorption and can use for protein protection against ruminal degradability.
