Total mixed ration (TMR) samples (n = 110) were analyzed for dry matter (DM), crude protein (CP), soluble CP, neutral detergent fiber (NDF), NDF CP, starch, ash, fat, total ethanol-soluble carbohydrate, and nonfiber carbohydrate (NFC). Rapidly and slowly degraded and undegraded in situ CP fractions and in vitro DM, organic matter, and NDF digestibility were determined on each TMR. The TMR were ...

The effects of urea and rumen-degradable protein (RDP) on microbial growth, digestibility, and fermentation were examined using dual-flow continuous culture. The experimental design was a 4 x 4 Latin square with a 2 x 2 factorial arrangement of treatments. Factors were urea infusion (0.4 g/L of artificial saliva) and RDP concentration, and the treatments were as follows: 1) low RDP (8% of dieta...

Materials that display multiple carbohydrate residues have gained much attention due to their potential to inhibit or modulate biological multivalent interactions. These materials can be grouped accordingly to the way they are prepared, as unimolecular or as self-assembled systems. Both systems take advantage of the fact that multivalent interactions have significantly higher binding affinity t...

Light irradiation plays an important role in the growth of microalgae and their nutrient composition. To elucidate effect different LED lights (red, orange, green, blue, purple, simulated sunlight, white) on main nutritional compositions Isochrysis zhanjiangensis, growth, fatty acid composition, soluble carbohydrate, protein contents were studied. The results show that I. zhanjiangensis grew fa...

The impact of water-soluble carbohydrate composition in relation to damage levels of onion thrips (Thrips tabaci Lindeman), were studied under field conditions at the Experimental Field of the Biotechnical Faculty in Ljubljana on 7 cabbage cultivar (Brassica oleracea L. var. capitata). Onion thrips showed weak preference on cabbage heads with high amount of total carbohydrate, fructose and gluc...

Onion bulbs accumulate fructans, a type of soluble carbohydrate associated with lower rates of colorectal cancers. Higher fructan concentrations in bulbs are correlated with higher pungency, longer dormancy, and greater onion-induced antiplatelet activity (OIAA). We analyzed replicated field trials of a segregating family for types and concentrations of soluble carbohydrates in onion bulbs 90 d...

Sugarcane juice contains a lot of sucrose associated with several monosaccharides, defined as low molecular mass carbohydrates (LMMC), as well as some polysaccharides and glycoproteins, which are defined as mid and high molecular mass carbohydrates (MMMC and HMMC, respectively). These three categories of carbohydrates can be separated by size-exclusion chromatography through Sephadex G-10 and S...

1. Optimum conditions, including the effect of media of different pH values, were determined for the incorporation of radioactive precursors into mucoproteins by pig gastric mucosa in vitro. 2. Mucosal scrapings incorporated radioactivity from [U-(14)C]-glucose and from [G-(3)H]threonine or [G-(3)H]serine solely into the carbohydrate and protein portions respectively of the mucoprotein molecule...

The objectives of this study were to partition corn grain into three digestible fractions and to measure the rate of disappearance of these fractions in vitro. Seventeen corn grain samples with varied fiber concentrations were extracted with either 80% ethanol or neutral detergent to obtain estimates of the pool size and digestion kinetics of the A, B1, B2, and C fractions. The carbohydrate sol...
