Abstract

Amino acid protection is one of the efforts to improve livestock feed quality. Lysine is one of the limiting amino acids, which is easily degraded in the rumen, and thus requires a protection. This study aimed to determine the effect of protected lysine on cattle's digestive system and ruminal ecology in vitro. This study used encapsulation using xanthan gum and tannin (2% w/v) to protect lysine. The treatments consisted of P0 = unprotected amino acids; P1 = amino acids + 2 g xanthan gum; P2 = amino acids + 2 g tannin; P3 = amino acids + 2 g xanthan gum + 2 g tannin. Parameters observed included nutrient content, chemical activity, degradability of organic matter (OM) and crude protein (CP), and rumen fermentability (pH, N-NH3, VFA, gas kinetics, and CH4). A combination of xanthan gum and tannin coatings (P3) resulted in a higher effect (p<0.05) on rumen fermentation compared to others. The Undegraded DM and CP values in the rumen were 48% and 32%, respectively, and in the pepsin-HCl were 15% and 89%. All treatments did not change the rumen fermentability. In conclusion, protected amino acids has a effect on the cattle digestion system without disturbing the rumen ecology. Combining xanthan gum and tannin coatings provides the best results than using a single type of coating. Key words: amino acids, encapsulation, rumen fermentation, tannin, xanthan gum

Abstract

The Borneo earless monitor lizard (Lanthanotus borneensis) is one of the endemic animals of Indonesia. In 2019, the IUCN listed L. borneensis as an ‘endangered’ species. The declining population of the L. borneensis is a major concern for conservation efforts. One of the efforts to conserve endangered wild animals is to know the gut microbiome profile and the relationship between the host and the bacterial community in the body, which is associated with an influence on health. This research aims to determine the gut microbiome profile of animals with metagenomic analysis using Next-Generation Sequencing (NGS). This research was carried out by providing three feed types: earthworms, shrimp, and fish. Sample feces was collected by cloacal swabs and the DNA was sequenced using the Illumina NGS technique in the V4 16S rRNA region to examine the gut microbiome. The results of the metagenomic analysis showed differences in bacterial abundance in each feed treatment. The L. borneensis treated with earthworms and fish were dominated at the phylum level by Proteobacteria and Bacteriodota, while in shrimp, the phyla were Proteobacteria and Firmicutes. Index Shanon, Simpson, and the rarefaction curve also showed the highest bacterial diversity found in the fish treatment. This study can be used as a reference in designing suitable feed formulations for effective captive breeding for the conservation of L. borneensis

Abstract

The purpose of this study was to determine how common Succinivibrionaceae bacteria are in calf feces. Four female calves, with an average age of 6.48 ± 0.51 months, participated in a Latin square trial featuring four dietary treatments: control (C), tannin (T), amino acid (AA), and a tannin-amino acid mixture (TM). Duration of each treatment was 14 days whereby faecal samples were that were harvested on day 14. The treatment trial for 14 days included the collection of faecal samples on day 14 for the extraction of DNA to conduct Next-Generation Sequencing (NGS) analysis. Results showed that the Succinivibrionaceae population grew extensively when treated with T and AA and TM compared with C while AA was most effective. Analysis of bacteria detected five genera and five species. The bacterial genus Ruminobacter dominated in the C (53%) and AA (62%) and TM (58%) treatment groups while Succinivibrio dominated the T treatment group (78%). The species Ruminobacter amylophilus dominated treatments C, AA, and TM but the species Succinivibrio dextrinsolvens dominated treatment T. The results infer that the addition of tannins or amino acids or their combination to the gut environment may help in reducing methane emissions through an alteration in the microbiome composition.

Abstract

Saponins are secondary plant metabolites binding hydrophobic non-sugar components that can reduce ruminant methane (CH4) production. Previous studies revealed that tea saponin is one of the common sources of saponins used to reduce enteric CH4 production. However, the effect of different levels of dietary tea saponin on rumen fermentation remains inconclusive. This study aimed to investigate the effect of tea saponin on in vitro rumen fermentation and methane production through a meta-analysis approach. A total of 6 articles were selected and included in the meta-analysis database, continued by the statistical analysis using SAS software through mixed model formula. The results showed that tea saponin levels lowered in vitro organic matter degradability (IVOMD) and in vitro dried matter degradability (IVDMD; P=0.01) by a linear response. Furthermore, increased tea saponin levels in the diet reduced enteric CH4 emission expressed as CH4/DM substrate and CH4/IVOMD by a quadratic (P=0.01) and a linear response (P=0.04), respectively. Increased tea saponin levels also tended to decrease gas production linearly (P=0.08). Tea saponins inclusion also decreased pH levels linearly (P=0.04) but increased NH3 quadratically (P=0.01). Moreover, total VFA concentration in the rumen also raised quadratically, followed by the increased acetate (C2) and propionate (C3) proportion by a linear response (P<0.05). As a result, the C2/C3 ratio was decreased in a linear response (P=0.01) by the increased tea saponin levels, where the protozoa population was also diminished by a quadratic response (P=0.01). In conclusion, tea saponin levels directly reduced enteric CH4 production by diminishing microbial populations.
