Optimizing Ruminal Fermentation with Organic Acids
Much interest has been generated over the past few years aimed at evaluating alternative means to manipulate the gastrointestinal microflora in production livestock. Motivation for examining these alternatives comes from increasing public scrutiny about the use of antibiotics in the animal feed industry. However, compared to the amount of information available detailing the effects of antimicro...
متن کاملIn Vitro Stimulation of Forage Fiber Degradation by Ruminal Microorganisms with Aspergillus oryzae Fermentation Extract.
Aspergillus oryzae fermentation extract (Amaferm) was evaluated for its ability to influence degradation of brome grass and switchgrass fiber fractions by mixed ruminal microorganisms in vitro. Addition of Amaferm at a concentration of 0.067 mg/ml, which is approximately the concentration found in the rumen ecosystem (0.06 mg/ml), increased the degradation of brome grass neutral detergent fiber...
متن کاملIn vitro Assessment of Adsorbents to Counteract Lead Toxicity in Ruminal Fermentation
An in vitro gas production technique was used to evaluate the effects of different adsorbents on the gas production parameters of lead-exposed diet. Ruminal fluid, obtained from fistulated sheep (3-4 years of age and 40±5 kg BW), and experimental diets samples, 200 ± 0.2 mg DM, were incubated in 100 mL glass bottles. To each bottle, one of the following treatments was applied: 1) control (no Pb...
متن کاملEffect of Aflatoxin B1 on In Vitro Digestibility and Ruminal Fermentation of Sheep Diet
The aim of this study was to investigate the effect of different levels of aflatoxin on the gas production, in vitro fermentation parameters, dry matter and organic matter digestibility of sheep's diet. This experiment was conducted in a completely randomized design with 5 treatments and 4 replicate per treatment. The treatments included 1.diet without aflatoxin and methanol (control), 2.c...
متن کاملEffects of Branched-chain Amino Acids on In vitro Ruminal Fermentation of Wheat Straw
This study investigates the effects of three branched-chain amino acids (BCAA; valine, leucine, and isoleucine) on the in vitro ruminal fermentation of wheat straw using batch cultures of mixed ruminal microorganisms. BCAA were added to the buffered ruminal fluid at a concentration of 0, 2, 4, 7, or 10 mmol/L. After 72 h of anaerobic incubation, pH, volatile fatty acids (VFA), and ammonia nitro...
