OBJECTIVE To compare the ileal digestibility of protein and amino acids in parental rice and rice genetically modified with sck gene. METHODS Six experimental swines were surgically fixed with a simple T-cannula at the terminal ileum and fed with parental rice and rice genetically modified with sck gene alternately. The ileum digesta were collected and analyzed for determination of apparent a...

The need of quality protein in the aquaculture sector has forced the incorporation of alternative plant proteins into feeding diets. However, most plant proteins show lower digestibility levels than fish meal proteins, especially in carnivorous fishes. Manipulation of protein content by plant breeding can improve the digestibility rate of plant proteins in fish, but the identification of low di...

The protein digestibility-corrected amino acid score (PDCAAS) has been recommended to be the most suitable method for routine evaluation of protein quality of foods by FAO/WHO. The PDCAAS method includes the use of young rats for predicting protein digestibility of foods for all ages including the elderly. To assess the usefulness of protein digestibility in old rats in the calculation of PDCAA...

Two trials were conducted to determine the adequacy of ADIN as an indicator of N digestibility. In Trial 1, eight nonforage plant protein sources were heated at 150 degrees C for 90 min in the presence of xylose (12.8% of CP, DM basis) to produce heat damage. Thirty-four wethers (average BW 40 kg +/- 9.9) were used to determine the effect of heat on N digestibility. Differences in ADIN were evi...

abstract- annual medicago species (medicago spp.) are native to the mediterranean region and widely used in fields and pastures in iran. there are several methods of sowing annual medicago species, each with different effects on the performance. however, there is currently no sufficient information about the appropriate methods for sowing medicago species. in order to evaluate methods of sowing...
