“…The production of ammonia (NH 3 ) in the rumen was also an important parameter because NH 3 is a compound produced from the protein degradation process in the rumen (Suryani et al 2020). Suryapratama and Suhartati (2012) stated that NH 3 in the rumen was needed as a nitrogen source for rumen microbes.…”

Abstract. Agustina S, Wiryawan KG, Suharti S, Meryandini A. 2021. The enrichment process and morphological identification of anaerobic fungi isolated from buffalo rumen. Biodiversitas 23: 469-477. Anaerobic fungi are one of the microbes that have an important role in rumen fiber degradation because they can produce cellulase enzymes and penetrate feed particles. Nevertheless, few studies were performed to test the potential of anaerobic fungi in Indonesia. Therefore, the present study was carried out to evaluate the impact of the enrichment process on pH value, the zoospores population, NH3 (ammonia) concentration, and VFA (Volatile Fatty Acid) proportion. In addition, this research was also performed to isolate anaerobic fungi from buffalo rumen and identify their morphological characteristics. The enrichment stage of anaerobic fungi was carried out using the Hungate method. Results showed that the population of fungi zoospores, pH value, ammonia concentration, the proportion of acetate, and total VFA were significantly affected by the incubation time (P<0.01). In addition, Caecomyces, Neocallimastix, and Piromyces were rumen anaerobic fungi isolated from buffalo rumen with different morphological characteristics. It can be concluded that the incubation time increased the zoospore population, the concentration of NH3, acetate proportion, and total VFA but decreased media's pH value.

“…The primary products of microbial fermentation are volatile fatty acid (VFA) and ammonia (NH3), and their production represents diet degradation in the rumen. Soluble carbohydrates and protein content in the feed are the main factors influencing VFA and NH3 concentrations in the rumen [28,29]. Therefore, in this study, we employed the MSC+SG+D1 spectra correction technique to build VFA, NH3 and pH calibration models for predicting the level of feed degradation.…”

This study elucidates the application of near-infrared spectroscopy (NIRS) and multivariate analysis for the rapid, non-destructive determination of animal feed nutritive parameters, specifically pH, NH3, and volatile fatty acid (VFA) values. NIRS spectra within the 1000-2500 nm range, coupled with reference methods, were employed for parameter determination. To enhance prediction accuracy, spectral pre-processing was undertaken using multiplicative scatter correction (MSC), Savitzky-Golay (SG) smoothing, and first-derivative methods. Simultaneous determination of nutritive parameters was achieved through the establishment of prediction models employing three multivariate analyses: principal component regression (PCR), partial least squares regression (PLSR), and support vector machine regression (SVMR). The results indicated superior pH (r=0.993) and NH3 (r=0.987) predictions using SVMR, while PLSR yielded the lowest root mean square error (RMSE) for VFA (r=0.998). These findings suggest that with appropriate spectral corrections and regression methodologies, NIRS can be effectively utilized for the rapid, simultaneous determination of animal feed nutritive parameters.

This study aimed to study the botanical composition and feed quality for swamp buffalo in Jembrana Regency, province of Bali - Indonesia. Research using the survey method use samples obtained by proportional stratified sampling for the five districts in Jembrana Regency. Measuring the production and botanical composition of forage was carried out by using the square in the “Actual Weight Estimate” method. Chemical analysis of the feed carried out at the Laboratory of Nutrition and Animal Feed Science, Faculty of Animal Husbandry, University of Udayana. The results showed that the botanical composition of forage for swamp buffalo consisted of Brachiaria reptans, Panikum repen, Lercia Hexandra, Cynodon dactylon, Ischainum sp, Digitaria sp, Alysicarpus vaginalis, and weed. Only Alysicarpus vaginalis as leguminous plants have been detected. The crude protein content of the ration was quite high, namely 12.94% with a digestibility of 66.73%. Based on the results of the study, it can be concluded that the botanical composition of forage for swamp buffalo in Jembrana Regency is quite diverse with good quality. Leguminous plant introduction needs to be done to improve feed quality.
