Effects of supplemental glucose and degradable intake protein on nutrient digestion and urea kinetics in steers (Bos taurus) given ad libitum access to prairie hay (4.7% CP) were quantified. Six ruminally and duodenally cannulated steers (initial BW 391 kg) were used in a 4 × 4 Latin square with 2 extra steers. Treatments were arranged as a 2 × 2 factorial and included 0 or 1.2 kg of glucose an...

Nitrogen components of yoghurt milk samples and resulting probiotic set yoghurt weredetermined. Analyses included total nitrogen (TN), non-casein nitrogen (NCN), non-proteinnitrogen (NPN), casein nitrogen (CN) and proteolysis index (PI). Yoghurt samples wereanalyzed 1, 7, 14 and 21days after production and storage at 5±1°C. TN, CN and PI contentsof yoghurt milk samples with high Somatic Cell SC...

The functionality of casein that was precipitated by batch by a novel process using CO2 was investigated for solubility in water and NaCl, foam stability, overrun, emulsion activity index, and emulsion stability. These properties were compared with those of acidified casein and Na caseinate prepared in the laboratory, commercial acid casein, and commercial Na caseinate and Ca caseinates. The pH...

A method was devised to construct stable and steep chemical gradients in slide cultures to study the movements of gliding cells. The movement of Myxococcus xanthus individual cells and small swarms was studied in these gradients. There was no response to gradients of Casitone and yeast extract that were previously reported to stimulate a positive chemotactic response with M. xanthus.

In the food industry, production processes and products are subjected to highest possible quality control requirements. order safeguard of a certain product along chain, it is important know its composition. This, for instance, especially applies natural like milk further processing in efficiently cheese quark. Milk contains an protein that responsible essential curdling process during cheese: ...

Due to their excellent nutritional (e.g., high calcium) and functional heat stability gelation) properties, the use of protein-enriched, micellar casein-dominant dairy powders, including milk protein concentrate/isolate casein concentrate, has increased considerably among food beverage manufacturers. However, poor often inconsistent rehydration properties these powders in water, specifically lo...

κ-casein is a glycosilated protein in mammalian milk that plays an essential role in the milk micelles. control of κ-casein expression reflects this essential role, although an understanding of the mechanisms involved lags behind that of the other milk protein genes. transcriptional regulation, a first mechanism for controlling the development of organisms, is carried out by transcription facto...

A protein kinase, able to phosphorylate casein, phosvitin, and glycogen synthase, was purified approximately 9000-fold from rabbit liver, and appeared analogous to an enzyme studied by Itarte and Huang (Itarte, E., and Huang, K.-P. (1979) J. Biol. Chem. 254, 4052-4057). This enzyme, designated here casein kinase-1, was shown to be a distinct glycogen synthase kinase and in particular to be diff...
