Continuous chromatographic separator techniques have allowed the extraction of more simple sugars from molasses (MOL). The resultant byproduct, concentrated separator byproduct (CSB), has reduced readily fermentable carbohydrates but elevated CP and mineral content. The feed value of CSB was compared to that of MOL in two separate trials. In Trial 1, a chopped forage mixture containing 8 4 O/O ...

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...

A study was conducted to evaluate the main effects of dietary nitrate adaptation by cattle and alfalfa cell wall to starch ratio in in vitro substrates on nitrate disappearance and nitrite and volatile fatty acid (VFA) concentrations, as well as hydrogen (H2) and methane (CH4) accumulations. Rumen fluid from steers fed diets containing urea or nitrate was added into in vitro incubations contain...

AIM The present study was conducted to examine the rumen modulatory effect of thyme, clove and peppermint oils on rumen fermentation pattern in vitro using roughage based diet. MATERIALS AND METHODS Thyme, clove and peppermint oils were tested at concentration of 0, 30, 300 and 600 mg/l (ppm) of total culture fluid using in vitro gas production technique in wheat straw based diet (concentrate...

the effect of phosphorus supplementation to ammoniated rice straw was studied. the in vitro experiment was carried out following the first stage of tilley and terry method. the treatments consisting of four diets were a= 50% ammoniated rice straw + 50% concentrate (control), b= a + 0.2% phosphorus (p) supplement, c= a + 0.4% phosphorus (p) supplement, and d= a + 0.6% phosphorus (p) supplement o...


 This study aims to determine the physical quality, dry matter digestibility, organic N-NH3, and total VFA of rice straw silage added with various legumes. research was conducted at Farm Sesetan Laboratory Animal Nutrition Forage Laboratory, Faculty Husbandry Udayana University from No- vember December 2020. The design used a completely randomized (CRD) five treatments four replications w...

the experiment was designed to investigate the effects of saccharomyces cerevisiae supplementation on the efficiency of rations containing different levels of concentrate in male holstein calves. 36 male holstein calves (average body weight of 175. 9 ± 5.54 kg) were allocated into six treatments of 60, 70 and 80 percent of concentrate with or without yeast culture based on a 2 x 3 factorial des...

The objectives of this study were to evaluate the influence of diet composition on ruminal parameters, more particularly redox potential (Eh). Four Holstein dry dairy cows, fitted with ruminal cannulas, were allocated in a 4 × 4 Latin square design. They were given four experimental hay-based diets D0, D25, D42 and D56 consisting of 0%, 25%, 42% and 56% of ground wheat and barley concentrate mi...

The effect of different phytogenic feed additives on reducing odorous compounds in swine was investigated using in vitro fermentation and analyzed their microbial communities. Soybean meal (1%) added with 0.1% different phytogenic feed additives (FA) were in vitro fermented using swine fecal slurries and anaerobically incubated for 12 and 24 h. The phytogenic FAs used were red ginseng barn powd...
