13. In vitro rumen fermentation and effect of protein fractions of canola meals on methane production
ABSTRACT: Canola provides oil for human consumption and a by-product from the extraction of its oil canola meal (CM), is used as a good quality protein and lipid supplement for ruminants. The aim of this study was to determine the chemical composition and fermentation profile associated with the potential for methane production of three types of CM: solvent-

14. In vitro fermentation characteristics of ruminant diets using ethanol extract of brown propolis as a nutritional additive
ABSTRACT The addition of levels of ethanol extract of brown propolis was evaluated by assessing diet degradation in rumen fluid and predicting cumulative in vitro gas production by nonlinear (dual pool logistic and exponential) models. A total of 35 g of crude propolis were extracted in 65 mL of cereal alcohol (95% ethanol). In a completely randomized factor

15. Effects of Yucca schidigera on gas mitigation in livestock production: A review
ABSTRACT Yucca schidigera extract (YSE) has received much interest in the application of manure deodorization and hazardous gas mitigation in livestock rearing conditions. The main objective of this review article was to summarize the current knowledge regarding YSE towards its gas mitigation from livestock excrement. Saponins have been considered to be vita

16. Effect of calcium propionate and monensin on in vitro digestibility and gas production
ABSTRACT An evaluation of the effects of monensin and calcium propionate on the in vitro kinetics of gas production, digestibility, carbon dioxide, and minor gas production on different days was performed using the ruminal fluid from eight Suffolk lamb donors, after receiving additives for 1, 10, and 20 days. Treatments consisted of a control ration of 40% g

17. Additives on in vitro ruminal fermentation characteristics of rice straw
ABSTRACT The objective of this study was to evaluate the effects of mineral and protein-energy (MPES), exogenous fibrolytic enzyme supplements (ES), combination of MPES + ES, and straw without supplement (WS) on digestibility, fermentation kinetic parameters, cumulative gas production, methane, CO2 production, and volatile fatty acid concentration of rice st

18. Isolation and characterization of yeasts from fermented apple bagasse as additives for ruminant feeding
Abstract Solid-state fermentation can be used to produce feeds for ruminants, which can provide an enriched population of yeasts to improve ruminal fermentation. Fermentation of apple bagasse was performed to obtain a yeast-rich product, with the objective of isolating, identifying, and characterizing yeast strains and testing their capability to enhance in

19. In vitro effects of Melaleuca alternifolia essential oil on growth and production of volatile sulphur compounds by oral bacteria
ABSTRACT Objective Halitosis can be caused by microorganisms that produce volatile sulphur compounds (VSCs), which colonize the surface of the tongue and subgingival sites. Studies have reported that the use of natural products can reduce the bacterial load and, consequently, the development of halitosis. The aim of this study was to evaluate the antimicro

20. In-vitro screening of Kalahari browse species for rumen methane mitigation
The nutritional value of browse foliage from the Thorny Kalahari Dune Bush veld of South Africa is not characterized. Most of this browse species is rich in tannin, but still palatable, and is consumed by ruminants during the dry season, as well as having a role to play in mitigating enteric methane emission from ruminants. In this study, the rumen methane m

21. Antileishmanial activity of the essential oil from Tetradenia riparia obtained in different seasons
The herbaceous shrub Tetradenia riparia has been traditionally used to treat inflammatory and infectious diseases. Recently, a study showed that T. riparia essential oil (TrEO) obtained in summer has antileishmanial effects, although these results could be influenced by seasonal variation. This study evaluated the activity of the TrEO obtained in different s

22. Degradação e produção de gases in vitro de glicerina da cadeia produtiva do biodiesel
his study was realized to evaluate the production of gas and volatile fatty acids when glycerin was used to replace four forage species through the use of a semi-automated technique in vitro. The experimental design included 4 treatments and 4 replications. The treatments consisted of increasing levels of glycerin (0, 30, 50 and 70%), which was used to repla

23. Wasted cabbage (Brassica oleracea) silages treated with different levels of ground corn andsilage inoculant
Our objective was to evaluate the chemical composition, fermentation profile, and aerobic stability of cabbage silages treated with ground corn and inoculant. The evaluated treatments were: addition of 200, 300, 400, 500, and 600 g of ground corn per kilogram of cabbage (fresh matter basis), with or without a bacterial inoculant composed of Lactobacillus pla

24. Cinética ruminal de dietas contendo farelo de mamona destoxificado
The kinetics of gas production and in vitro ruminal degradation of diets contained replacement of soybean meal (SBM) by detoxicated castorbean meal (DCBM) (0, 15, 30 and 45% of substitution) were evaluated in this study. Values of gas production of non-fibrous carbohydrates (Vf1), fibrous carbohydrates (Vf2) and total carbohydrates (V) showed quadratic behav
