Abstract

Tofu dregs are one of the high-protein feed ingredients and it is highly palatable for livestock, particularly ruminants. However, tofu dregs have the main disadvantage, i.e., they easily deteriorate due to their high water and protein contents. Fermentation of tofu dregs may be applied in order to prevent such deterioration. The aim of this experiment was to evaluate tofu dregs as influenced by fermentation and tannin extract from acacia bark on in vitro rumen fermentation and digestibility parameters. The experimental treatments were: NK (tofu dregs without fermentation and 0% tannin), NA (tofu dregs without fermentation and 2% tannin), FK (tofu dregs with fermentation and 0% tannin), and FA (tofu dregs with fermentation and 2% tannin). Data were analyzed by analysis of variance according to a randomized complete block design with four treatments and four replications. Results revealed tofu dregs with fermentation treatment have a significant increase (P<0.05) in gas production, and ammonia but do not affect other parameters such as propionic acid and butyric acid on fermentation products. Opposite to the rumen fermentation product, the tannin gives a significant effect (P<0.05) on all digestibility parameters so can be concluded tofu dregs with fermentation and tannin approaches affect to rumen fermentation product and tannin has a weaker effect than fermentation even though 20 g/kg addition decrease digestibility of rumen in vitro.Keywords: ruminal fermentation product, silage, tannin, tofu dregs

Abstract

Background. The large number of species spread across Indonesia cannot be separated from the domestication process which helps improve and maintain livestock species by humans to maintain food needs for animals such as the domestication of the Sentul chicken. Poor feed efficiency for Sentul chickens has caused Sentul chickens to depend on antibiotics and has been banned since 2018. Lactic acid is believed to be an alternative to antibiotics and has been studied for a long time. The liver is an organ that can represent the state of the chicken if lactic acid is identified as a hazardous substance through the content of SGPT and SGOT. This study aims to evaluate the use of lactic acid as an acidifier in sentul chickens found in the liver seen from the content of SGOT and SGPT. Materials and Methods. There were 60 Sentul chickens used in this study which measured the content of SGOT and SGPT. Results. The addition of lactic acid significantly (p>0.05) did not have a negative effect on the liver in both SGOT and SGPT at administration levels up to 2% (v/g). SGOT and SGPT in the negative control were 232.9 and 39.68 mmol/L while the addition of lactic acid was still in a range that was not too far away, namely for SGOT in the range of 234.6-281.2 mmol/L and SGPT 35.15-56.96 mmol/L. Conclusion. The use of lactic acid in Sentul chicken feed does not cause liver damage which can be seen in SGOT and SGPT levels.
