“…Furthermore, the addition of tannins did not alter the NDF and ADF contents, which has also been reported by other studies [28,29]. Such unchanged NDF and ADF contents in silage indicate the lower affinity of tannins on fiber components compared to protein [9].…”

“…Tannins are a naturally occurring polyphenol that have the ability to interact with other molecules, particularly protein, due to the presence of hydroxyl groups in their structure [8]. A previous study reported that tannin extract from chestnuts could inhibit proteolysis in Moringa and Indigofera leaf silages, as indicated by the lower ammonia (NH 3 ) concentration [9]. Furthermore, a meta-analysis revealed that higher tannin levels in the ensiled material resulted in lower NH 3 and butyrate concentrations [10], indicating its potential application as a silage additive.…”

Aim: The present experiment aimed to evaluate the use of different additives, i.e., lactic acid bacteria (LAB) inoculant, tannin extract, and propionic acid, on the chemical composition, fermentative characteristics, and in vitro ruminal fermentation of soy sauce by-product (SSB) silage. Materials and Methods: SSB was subjected to seven silage additive treatments: Fresh SSB, ensiled SSB, ensiled SSB+LAB, ensiled SSB+2% acacia tannin, ensiled SSB+2% chestnut tannin, ensiled SSB+0.5% propionic acid, and ensiled SSB+1% acacia tannin+1% chestnut tannin+0.5% propionic acid. Ensiling was performed for 30 days in three replicates, and each replicate was made in duplicate. The samples were evaluated for their chemical composition and silage fermentation characteristics and were tested in an in vitro rumen fermentation system. Results: In general, the nutrient compositions did not differ among the tested SSBs in response to the different additives used. The addition of tannins, either acacia or chestnut, and propionic acid significantly decreased the pH of the ensiled SSB (p<0.05). The addition of several additives (except LAB) decreased the ammonia concentration in SSB silage (p<0.05). The total volatile fatty acids in the in vitro rumen fermentation profile of the ensiled SSB were not significantly altered by the various additives applied. The addition of some additives, i.e., ensiled SSB+LAB and ensiled SSB+2% acacia tannin, reduced the digestibility values of the SSB (p<0.05). Different silage additives did not significantly affect methane production, although the addition of acacia tannins tended to result in the lowest methane production among treatments. Conclusion: The use of additives, particularly 2% acacia tannins, can reduce proteolysis in SSB silage.

“…In this study, the best pH, total VFA, and NH 3 values were achieved using the rations with I. zollingeriana (IZ I and IZ II). In this study, the pH range (6.9 to 7) of the rumen fluid on the basis of the I. zollingeriana (freshly cut) ration was at an ideal level compared to the pH ranges reported by the previous studies that used feed preservation technology in the form of Indigofera silage and pellet [36,37]. The NH 3 production differed significantly (p<0.05) among groups and was highest in IZ I.…”

Aim: The aim of this study was to evaluate the effects of various combinations of tropical grass-legume species in rations on the biohydrogenation (BH) activity of unsaturated fatty acids (FAs), C18:0 composition, and fermentation profile in an in vitro rumen system. Materials and Methods: Samples of the following five fodder plants were used: One species of grass (Pennisetum purpureum) and four species of tree legumes (Leucaena leucocephala, Gliricidia sepium, Calliandra calothyrsus, and Indigofera zollingeriana). The following eight experimental diets were evaluated: 50% P. purpureum + 50% L. leucocephala (LL I); 50% P. purpureum + 50% G. sepium (GS I); 50% P. purpureum + 50% C. calothyrsus (CC I); 50% P. purpureum + 50% I. zollingeriana (IZ I); 75% P. purpureum + 25% L. leucocephala (LL II); 75% P. purpureum + 25% G. sepium (GS II); 75% P. purpureum + 25% C. calothyrsus (CC II); and 75% P. purpureum + 25% I. zollingeriana (IZ II). Each ration was replicated 3 times. In vitro rumen incubation was performed for 48 h, according to the Tilley and Terry method. Determination of the FA profiles of the forage materials and rumen fluid samples was performed using gas chromatography. Results: The percentage of polyunsaturated FA (PUFA) in the forage materials ranged from 34.18% (P. purpureum) to 74.51% (C. calothyrsus). The percentage of monounsaturated FA (MUFA) ranged from 5.06% (P. purpureum) to 8.71% (L. leucocephala). The percentage of saturated FA (SFA) was the lowest at 19.12% (C. calothyrsus) and highest at 60.76% (P. purpureum). In vitro BH of C18:3 n-3, C18:2 n-6, C18:1 n-9, and C18 PUFA in the experimental diets ranged from 72% to 100%. The BH of C18:1 n-9 in GS I (80%) and IZ I (72%) was significantly different (p<0.05). The percentage of C18:0 was 10-50% and significantly different (p<0.05) among treatments, with the highest (of 50%) in GS II. No significant differences (p>0.05) were observed in the fermentation parameters (pH, total volatile FAs, in vitro dry matter digestibility, and in vitro organic matter digestibility) among the treatments, except in NH3 concentration (p<0.05). Conclusion: The various combinations of tropical legumes do not have significant inhibitory effects on the BH of C18:2 n-6, C18:3 n-3, and C18 PUFA after in vitro incubation for 48 h. Furthermore, an increase in the tropical legume ratio in the ration tends to suppress C18:0 formation after the fermentation simulation process. IZ I has the potential to reduce C18:1 n-9 (MUFA) disappearance and yield an ideal rumen fermentation profile.

“…This tannin can only release its bonds with feed ingredients by enzymes in the small intestine and low pH levels, while in the rumen, tannins are problematic in the rumen bacterial break and normal rumen pH (Jamarun and Zain 2013). Tannin addition increased neutral detergent insoluble crude protein (NDICP) and acid detergent insoluble CP (ADICP) (Jayanegara et al 2019). However, the levels should not be excessive because if excessive phytochemicals can hurt livestock productivity.…”

Abstract. Jamarun N, Pazla R, Arief, Jayanegara A, Yanti G. 2020. Chemical composition and rumen fermentation profile of mangrove leaves (Avicennia marina) from West Sumatra, Indonesia. Biodiversitas 21: 5230-5236. This study aimed to determine the potential of mangrove leaves of Avicennia marina for ruminant animal feed. Laboratory tests were carried out on A. marina with three replicates. Parameters measured were proximate and fiber contents, rumen fluid profile (pH, NH3 and VFA), digestibility of nutrients (DM, Ash, CP, CF, NDF, ADF, cellulose, and hemicellulose), macro and micro mineral contents, and phytochemical compounds. The results showed the nutritional content of A. marina were CP 13.37%; Ash 7.17%; lignin 7.34%; TDN 79%, rumen fluid profile is in reasonable condition, digestibility of food substances is more than 50%, rich in macro and micro minerals and contains phytochemical compounds such as phenols, steroids, triterpenoids, and tannins. Macro and micro minerals content of Ca 0.38%, Na 0.20%, Mg 0.20%, K 0.48%, P 0.51%, S 0.01%, Cl 1.03%, Fe 388 ppm, Zn 164 ppm, Mn 211 ppm, and Cu 128 ppm. This research concludes that A. marina is very potential to be used as a ruminant animal feed.
