Abstract

Background. This study aims to examine the effect of using pineapple leaf waste silage as a substitute for elephant grass based on levels of Nitrogen-ammonia (N-NH3) and Volatile Fatty Acid (VFA) concentration in total rumen fluid of beef cattle in vitro. The research was conducted from August 25 to September 20, 2022 at the Laboratory of Nutrition and Animal Feed Science, Faculty of Animal Science, Jenderal Sudirman University, Purwokerto. Materials and methods. The study using an in vitro method with a completely randomized design, 5 treatments and each treatment was repeated 4 times so that there were 20 research units. The treatments used consisted of P0 (60% concentrate + 40% elephant grass), P1 (60% concentrate + 30% elephant grass + 10% pineapple leaf silage), P2 (60% concentrate + 20% elephant grass + 20% pineapple leaf silage), P3 (60% concentrate + 10% elephant grass + 30% pineapple leaf silage), and P4 (60% concentrate and 40% pineapple leaf silage). Results. The results showed that the treatment had no significant effect (P>0.05) on the levels of N-NH3 and the concentration of VFA. Conclusion. It was concluded that the use of pineapple leaf silage at a balance of 40% elephant grass and 60% concentrate could replace elephant grass in beef cattle feed up to 100% based on in vitro measurements of N-NH3 levels and total VFA concentrations.

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.
