“…Differences in grape processing could explain the variability in pomace activity due to the fact that content of different by-product compounds (pulp, granilla, stalk), are not always in the same proportions (Hixson et al, 2016) In line with our results, Atalay, 2020, also found differences for both gas and CH4 production after an incubation period of 24 h. In an in vitro fermentation study of dif-ferent grape varieties pomaces, Sofyan et al, 2017, also confirmed that the presence of tannins determines a decrease in gas production, but unlike our results, they find no differences in terms of CH4 production. Other authors such as Moate et al, 2014, demonstrated the reduction effect of grape by-products on CH4 production, by substi-tuting 36% of alfalfa hay with grape byproducts, obtaining a decrease between 20-24% of CH4 emissions in an in vivo study with cows.…”

Agricultural activity contributes actively to global warming by emitting greenhouse gases (GHGs) such as methane (CH4), being ruminants one of the main producers of this gas. On the other hand, there is excess of agro-industrial by-products such as grape pomace with a high polyphenolic concentration. Therefore, it is necessary to develop strategies to reduce both GHGs and agro-industrial residues. In this work, the use of the by-product grape pomace, rich in tannins, is proposed as a nutritional strategy to be incorporated in ruminant feed concentrates to reduce the production of ruminal CH4.For this, four grape pomaces Tempranillo variety (P1, P2, P3, P4) from different wineries, were added to a base concentrate such as barley at four levels (1.25%, 2.5%, 5% and 7.5%).These samples were fermented in vitro in two different periods of time (18 and 96 h). The kinetics of total gas and CH4 production were studied. A quantitative inhibitory effect was observed for both parameters when incorporating 7.5% grape pomace, as well as a variable qualitative effect depending on the fermentation time, being P3 the most effective pomace after 18 h and P2 after 96 h. Therefore, the incorporation of grape pomace in ruminant fattening feed could represent an alternative to the environmental problems of the agricultural sector within a green and circular economy model.

“…RJ0 treatment (basal diet without SCS supplementation) gives the highest gas production than other treatment, while RJ4 (basal diet with 1% commercial chitosan supplementation) give lowest gas production. Gas production is the result of fermentation caused by the amount of microbial activity occurring in the rumen, as well as showing the amount of digested organic material [22]. The gas production kinetics continue to increase from hours 0 to 48 hours.…”

The major goal of this study was to see how adding swimming crab shell to dietary feed affected in vitro gas production and fermentation of feed in ruminal fluid Completely Randomized Design (CRD) with five treatments and four replications was arranged on this research. The treatments are RJ0 as control negative (0% of SCS supplementation of DM), RJ1(10% SCS), RJ2 (20% SCS supplementation), RJ3 (30% SCS supplementation), and RJ4 as possitive control (1% commercial chitosan supplementation). The highest gas production given by RJ0 treatment than other treatment. Total gas production 1-48 hours, rate of gas production (c), microbial cell protein, IVDMD, IVOMD of supplementation of SCS was significantly affected by treatments (P<0.05). Gas production from total fraction (a+b), soluble fraction (a) and insoluble fraction (b), NH3 production, and ammount of protozoa indicated no significant difference (P>0.05) among treatments. In this study basal diets supplemented with 30% SCS treatment had the best result as chitosan source on rumen fermentation properties in vitro.

This experiment aimed to evaluate the effects of chitosan administration to total mixed ration (TMR) silage on ruminal fermentation characteristics and degradability by using both in vitro and in sacco methods. The completely randomized design (CRD) used in this study included five treatments and six replications. The treatments consisted of TMR silage with distilled water as control (SA), TMR with 1% acetic acid (SB), 0.5% chitosan in 1% acetic acid diluent (SC), 1% chitosan in 1% acetic acid diluent (SD), and 1.5% chitosan in 1% acetic acid diluent (SE). The variables observed were ruminal fermentation parameters, methane production and in sacco nutrient degradability. Results revealed that adding 1-1.5% chitosan (SD and SE treatments) reduced (P < 0.05) total protozoa, total gas production, methane production, the percentage of acetic acid, and the ratio of acetic acid to propionic acid, while it increased (P < 0.05) the proportion of propionic acid. The addition of chitosan (SE treatment) decreased (P < 0.05) the degradation of dry matter, but it increased (P < 0.05) the degradability of organic matter and crude protein, as determined by in sacco analysis.
