Use of Chick Plasma Non-Protein Nitrogen in Evaluating Fish Meals ,

Access and Rational use of Plasma Protein Therapies (PPTs)

Fish meals, fish components, and fish protein hydrolysates as potential ingredients in pet foods.

An experiment to determine the chemical composition and protein quality of 13 fish substrates (pollock by-products, n = 5; fish protein hydrolysates, n = 5; and fish meals, n = 3) was conducted. Two of these substrates, salmon protein hydrolysate (SPH) and salmon meal with crushed bones (SMB), were used to determine their palatability as components of dog diets. Pollock by-products differed in ...

Protein asymmetry in chick synaptosomal plasma membrane.

The topographical arrangement of chick synaptosomal plasma membrane polypeptides was examined by lactoperoxidase-catalyzed iodination and trypsin digestion of proteins exposed at the exterior surface. The ““I-labeling profile on sucrose gradients of lysed, subfractionated synaptosomes generally coincided with the activity of the membrane marker (Na+-K+)-activated ATPase, which suggested that la...

manufacturing of a slow-release non-protein nitrogen and evaluation of its use in ruminant nutrition

the possibility of manufacturing and effects of a slow release non-protein nitrogen product on ruminant nutrition were evaluated in two separate experiments. in first experiment, making of slow release component was followed by connecting branched carbon chain to the molecule of urea to reduce the degree of solubility. then, the sample product was analyzed to assess its chemical structure, and ...

The Partition of Non-protein Nitrogen in the Blood of Fresh Water Fish

The introduction of microchemical methods has made possible many biological investigations which were formerly precluded by the di5culty of obtaining sufficient amounts of material. This has been the case with studies on the blood and urine of fish. The only accurate quantitative chemical data are found in the recent papers of Dr. Denis’ on marine fish, where she reports results which indicate ...
