The objective of this study was to investigate the effects 11 active compounds essential oils (ACEO) on rumen fermentation characteristics and methane production. Two trials were conducted. In trial 1, ACEO (eugenol, carvacrol, citral, limonene, 1,4-cineole, p-cymene, linalool, bornyl acetate, α-pinene, β-pinene) at a dose 1,000 μL/L incubated for 24 h in diluted fluid with 70:30 forage:concentrate substrate (16.2% crude protein; 36.6% neutral detergent fiber). Three fistulated Holstein cows...
Summary In this study, the effects of seven pure plant secondary metabolites ( PSM s) on rumen fermentation, methane (CH 4 ) production and bacterial community composition were determined. Two in vitro trials conducted. trial 1, nine concentrations 8‐hydroxyquinoline, α ‐ terpineol, camphor, bornyl acetate, pinene, thymoquinone thymol incubated separate days using 24‐hr batch incubations. All compounds tested demonstrated ability to alter fermentation parameters decrease CH production....
Abstract This study investigated the combined effects of nitrate (NT) and medium-chain fatty acids (MCFA), including C8, C10, C12, C14, on methane (CH 4 ) production, rumen fermentation characteristics, bacteria using a 24 h batch incubation technique. Four types treatments were used: control (no nitrate, no MCFA), NT (nitrate at 3.65 mM), + MCFA mM one four 500 mg/L), MCFA/MCFA binary combination 250 mg/L). All decreased ( P < 0.001) methanogenesis (mL/g dry matter incubated) compared...
The aim of this study was to validate selected precision livestock farming (PLF) methods nutrition and feeding management high-yielding Holstein dairy cows. In a trial with 36 cows, the effect replacing 0.1 kg sodium bicarbonate in control total mixed ration (TMR-C) 1 wheat straw experimental (TMR-S) on physiological status cows amount milk produced (milk yield, MY) investigated. Feed intake time (FT), as measured using tensometric feed troughs (TFT), significantly longer TMR-S (188 min)...
Abstract The intestinal microbiota represents the largest and most complex microbial community inhabiting human body. Bifidobacteria lactobacilli represent important commensal bacteria with ability to utilize carbohydrates. main fermentation products from breakdown of dietary carbohydrates are short chain fatty acids (SCFAs). We examined faecal samples vegetarians (n = 10) conventional omnivores evaluate counts occurrence cultivable bacteria, especially bifidobacteria lactobacilli, using...
Objective: An experiment was conducted to determine the effect of partial replacement soybean meal (SBM) by white lupine seeds (WLS) on milk yield and quality, feed efficiency rumen fermentation high-yielding dairy cows.Methods: Thirty multiparous cows two breeds (20 Holstein 10 Czech Pied cows) in early mid-lactation received three diets (treatments) a 3×3 Latin square design with 28-d period. The dietary treatments were as follows: CON (control total mixed ration SBM, no WLS), WLS30 (30%...
Abstract The aim of this study was to evaluate the effects increasing concentrations three pure statins on in vitro methane production and rumen fermentation. atorvastatin, rosuvastatin simvastatin at (1, 10, 100 mg/L culture fluid) were evaluated using 24 h batch incubation buffered fluid with a 70:30 forage:concentrate substrate. All tested demonstrated ability reduce methanogenesis. Methane inhibition potential decreasing following order: simvastatin>atorvastatin>rosuvastatin....
Abstract This study aimed to evaluate the methane-reducing potential of individual and combined treatments low levels nitrate (NIT) a mixture capric/lauric acid (CL) in dairy cows. Both vitro vivo experiments were conducted. In experiment, anti-methanogenic effects NIT (1.825 mmol/l) CL (250 mg/l; capric acid, 125 mg/l + lauric mg/l) evaluated 2 × factorial design using consecutive batch incubations with rumen fluid. The reduced (P<0.05) methane production by 9.2% 21.3%, respectively....
Clostridium butyricum CBM 588 is used as a probiotic in eastern Asian countries and has been recently approved an animal feed additive the European Union. The purpose of this study was to evaluate effect C. MIYAIRI (CBM 588) on abundance selected genera caecal crop bacteria, volatile fatty acids growth performance broiler chickens. We studied counts anaerobic bacteria caeca crops chickens by plate-count method evaluated their performance. significantly reduced E. coli at days 10 42 also...
Abstract The objective of this study was to determine the effects geraniol and camphene at three dosages (300, 600, 900 mg l -1 ) on rumen microbial fermentation methane emission in vitro batch culture fluid supplied with a 60 : 40 forage concentrate substrate (16.2% crude protein, 33.1% neutral detergent fibre). ionophore antibiotic monensin (8 mg/l) used as positive control. Compared control, significantly (P < 0.05) reduced production increasing doses, reductions by 10.2, 66.9, 97.9%....
Abstract The inhibitory effect of four trace elements on production volatile fatty acids (VFA) and lactate was evaluated in cultures rumen contents containing lead, mercury, cadmium arsenic at 50, 100 250 μg/ml. VFA Pb 2+ , Hg Cd As 5+ 50 μg/ml decreased by 15.9, 40.0, 29.1 35.6%, respectively. molar profile variable, which suggests a different toxic tested groups microorganisms. Increasing concentrations proportion acetate increased that butyrate, whereas 2 percentages butyrate. Lactate...
This study used next-generation sequencing to assess the impact of combined capric acid (C10) and lauric (C12) on ruminal bacterial composition. Eight Holstein cows were randomly assigned two groups using a cross-over design. The fed silage-based diets with addition either 100 g stearic per cow day (control), or 50 (C10 + C12). On 18, 250 mL rumen fluid was collected from each cow, DNA isolated, amplified, sequenced. Treatment did not alter diversity indices, relative abundance archaea, nor...
Corn shredlage is a whole-plant corn silage with greater proportion of long particles and intensively processed stalks (by shredding peeling) kernels thorough crushing). may improve rumen function milk performance dairy cows, especially in low-fibre diets. Paradoxically, little known about the specific effects on fermentation. This study aimed to understand how dietary replacement changes feed intake, fermentation, rumination time, cows fed diet. Thirty-four lactating were allocated two...
