Short-chain fatty acids (SCFAs), primarily acetate, propionate, and butyrate, are metabolites formed by gut microbiota from complex dietary carbohydrates. Butyrate and acetate were reported to protect against diet-induced obesity without causing hypophagia, while propionate was shown to reduce food intake. However, the underlying mechanisms for these effects are unclear. It was suggested that S...

The presence of mycotoxins in feed has the potential to cause significant detriment animal and human health, even severe economic implications. Previous studies on effects mainly focused addition commercially available into feeds animals. In present study, corn meal cottonseed were kept warm humid conditions allow for produced then used substitute 50% 100% normal diets lactating cows 14 days. r...

Acetate, propionate, and butyrate are the main short-chain fatty acids (SCFAs) that arise from the fermentation of fibers by the colonic microbiota. While many studies focus on the regulatory role of SCFAs, their quantitative role as a catabolic or anabolic substrate for the host has received relatively little attention. To investigate this aspect, we infused conscious mice with physiological q...

OBJECTIVE This study was to examine in vivo digestibility, nitrogen balance and ruminal fermentation of tamarind (Tamarind indica) kernel powder extract residue (TKPER) compared to soybean products and by-products in wethers. METHODS Four wethers with initial body weight (BW) of 51.6±5.5 kg were assigned in a 4×4 Latin square design to investigate nutritional characteristics of TKPER, dry hea...

Two in vitro studies were carried out on nonlactating dairy cows. Experiment 1 compared the methanogenesis and rumen fermentation parameters of various microalgae (Spirulina platensis, Chlorella vulgaris, Schizochytrium spp.) protein feeds (sunflower meal, soybean alfalfa hay) with monensin (MON). Rumen determined by an gas production system. 2 ability three to prevent acidosis. They tested for...

Saponins are secondary plant metabolites binding hydrophobic non-sugar components that can reduce ruminant methane (CH4) production. Previous studies revealed tea saponin is one of the common sources saponins used to enteric CH4 However, effect different levels dietary on rumen fermentation remains inconclusive. This study aimed investigate in vitro and production through a meta-analysis approa...

The objective of this study was to systematically evaluate and compare the effects of select antimethanogen compounds on methane production, feed digestion and fermentation, and populations of ruminal bacteria and methanogens using in vitro cultures. Seven compounds, including 2-bromoethanesulphonate (BES), propynoic acid (PA), nitroethane (NE), ethyl trans-2-butenoate (ETB), 2-nitroethanol (2N...

The biosynthesis of monensin by Streptomyces cinnamonensis was studied by using (14)C-labeled glucose, acetate, propionate, butyrate, and methionine. The results indicated that the antibiotic is synthesized from five acetate, seven propionate, and one butyrate molecules. The o-methyl group of monensin is derived from methionine, whereas the terminal hydroxymethyl group is incorporated from acet...
