three experiments of 60 days duration were conducted in post larval stage of indian white shrimp, fenneropenaeus indicus, to explore the appropriate protein: lipid ratios in their diets. a common ingredient mixture consisting of; fish meal, shrimp meal, ground nut oil cake, cholesterol, lecithin, vitamins and minerals blended with chicken egg albumin, tapioca flour and cellulose (filler) was us...

A comprehensive study of feed staff animal origin was carried out to identify the most efficient ways use as components compound feeds. In samples feeds (fish meal, fish extrudate, meat and bone meal), parameters nutritional value safety were determined. It found that stable content crude protein essential critical amino acids characteristic which is advisable be used for purpose balancing youn...

Phytase increases the bioavailability of phytate phosphorus in seed-based animal feeds and reduces the phosphorus pollution of animal waste. Since most animal feeds for pellets are heated up to 65-80 °C, the production of a thermostable structure for phytase can be useful. In this study, we sought to perform bioinformatics analysis of the upstream region and protein structure of fungal phytase ...

Two patients with phenylketonuria (PKU) requiring treatment were fed on low protein milks. Both had blood phenylalanine levels below 1200 micronmol/l (20mg/100 ml) until given a phenylalanine challenge. Phenylalanine content of mature breast milk may provide intakes similar to those used in treating PKU. Diagnosis of PKU is unlikely to be missed if screening is carried out on the sixth or seven...

As an important constituent of animal feeds, fiber represents the portion of feeds that is bulky and difficult to digest. The neutral detergent fiber (NDF) method, developed over 30 years ago, is the method of choice for measuring total fiber in forages and other feeds. Several modifications that were made to improve its general applicability to all feeds and others developed in individual labo...

The aim of this study was to determine the correlations between output parameters in sacco method and CNCPS (Cornell Net Carbohydrate Protein System). Both methods were tested on 106 samples from feeds classified into following categories: extracted meal cakes, cereals, legumes, maize alfalfa silage, other silages, DDGS (dried distiller’s grains with solubles), oilseeds various hays. effective ...

The effect on lactational performance of replacing feed carbohydrate with fat at two different protein levels was studied. Lactating Sprague-Dawley rats with a standardized litter size of thirteen pups were allocated one of eight feeds containing either 300 or 150 g protein/kg organic matter (OM) and ranging in fat content from 100 to 550 g/kg OM from day 2 until day 14 of lactation. Daily food...

The objective of this work was to describe a novel in vitro system based on the subtraction of ammonia pools obtained with and without rumen fluid inoculum to determine the soluble protein fraction of feeds and their degradability, with adjustments for microbial contributions and bacterial contamination. Four corn-milling coproducts were used in this study as random factors. The feeds (Fd) were...
