PROTEOLYTIC enzymes in milk in relation to infant feeding.
Proteolytic Enzymes in Milk in Relation to Infant Feeding A REVIVAL of interest in the old practice’ of treating milk with proteolytic enzvmes for feeding infants has stimulated the Committee on Nutrition of the Amencan Academy of Pediatrics to undertake an appraisal of the significance of proteolytic enzymes in human and cow’s milk. It has been known for a long time that enzymic activity may b...
متن کاملffects of Using Wheat Gluten and Rice Protein Concentrate in Dairy Calf Milk Replacers
There is a limited amount of peer reviewed data on feeding milk replacers (MR) containing either hydrolyzed wheat gluten (HWG; 80% CP) or rice protein concentrate (RPC; 80% CP) to calves under 2 mo of age. Male Holstein calves less than 7 d old from multiple farms (trial 1) and 2to 3-d-old calves from one dairy farm (trials 2 and 3) were used. Trial 1 compared feeding 0.454 kg/d of 20% CP, 20% ...
متن کاملAntimicrobial Peptides Derived from Goat’s Milk Whey Proteins Obtained by Enzymatic Hydrolysis
In this study the bacterial growth inhibitory activity of peptide fragments produced from goat’s milk whey proteins by enzymatic hydrolysis using trypsin, ficin and a combination of both was investigated. Goat’s milk whey proteins were isolated and subjected to enzymatic hydrolysis and peptides were purified by ultrafiltration followed by reverse-phase high-performance liquid chromatography (RP...
متن کاملLiquid egg as an alternative protein source in calf milk replacers.
The use of alternative proteins in milk replacer has been evaluated for their ability to decrease the cost of milk replacers without negatively impacting performance of the calf. Three studies were conducted to evaluate the performance of calves fed milk replacer utilizing liquid egg as an alternative protein and to determine the optimal concentration of liquid egg to include in milk replacers....
متن کاملStudies on the production of milk-clotting enzymes, proteolytic enzymes and mucilage by fungi.
Of 48 fungal isolates, 28 (including one Penicillium and three Aspergilli) secreted milk-clotting enzymes. This activity was in general related to the mycelial growth of a given isolate, but not with pH change of the culture filtrate during incubation. It was not found when mucilage was formed by isolates capable of doing so. The ratio of general proteolytic activity to milk-clotting activity v...
