This study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal pH of sheep. The surface hydrophobicity of protein increased (P

Protein biofortification into crops is a means to combat childhood protein-energy malnutrition (PEM) in developing countries, by increasing the bioavailability of protein in staple plant foods and ensuring sustainability of the crop. Protein biofortification of sorghum has been achieved by both chemically induced mutation and genetic engineering. For this biofortification to be effective, the i...

Different raw materials are routinely used in aquaculture feeds to satisfy the dietary nutrients required by species. There several components that should be taken into account evaluation of a particular ingredient feed formulation, such as digestibility, palatability and nutrient utilization interference. The aim this review was produce global overview about alternative fish meal oil for gilth...

The development, refinement and validation of in vitro digestibility assays for dietary protein and amino acids for single stomached mammals are reviewed. The general principles of in vitro digestibility assays and their limitations are discussed. In vitro protein digestibility assays must be accurate, rapid, cheap, simple, robust, adaptable and relevant to the processes of digestion, absorptio...

BACKGROUND The FAO has recommended replacing the protein digestibility-corrected amino acid score (PDCAAS) with the digestible indispensable amino acid score (DIAAS). OBJECTIVE The objective of this study was to compare aspects underlying the calculation of the DIAAS and PDCAAS, including 1) fecal digestibility vs. ileal digestibility, 2) using a single nitrogen digestibility value for all am...

Experiments were conducted to evaluate the nutritional value of yellow-seeded rapeseed meal (YRSM). In the first experiment nutrient retention was recorded by 48 Arbor Acres-broiler chickens (28-d old) to determine AMEn (nitrogen-corrected apparent metabolizable energy), coefficient of apparent protein digestibility based on ileal digesta nitrogen, excreta nitrogen and uric acid nitrogen. The s...

To elucidate whether the digestibility is responsible for the hypocholesterolemic action of rice protein, the effects of rice proteins extracted by alkali (RP-A) and α-amylase (RP-E) on cholesterol metabolism were investigated in 7-week-old male Wistar rats fed cholesterol-free diets for 3 weeks. The in vitro and in vivo digestibility was significantly reduced by RP-A and RP-E as compared to ca...

persian sturgeon (acipenser persicus) is a valuable fish caught in the caspian sea. in this study, effect of frying, the most common cooking methods on nutritional properties of the persian sturgeon fillet were investigated. the raw and fried samples were analyzed for amino acid composition, protein and fat content, in vitro digestibility and nutritional parameters. the results showed that the ...
