Within groups of similar proteins-for example whale-meat meals or fish meals of different manufacturethere may be large differences in nutritive quality but only relatively small differences in amino acid composition. From chemical and microbiological tests (Bunyan & Price, 1960; Ford, 1962) it appears that the differences in quality may not be specifically related to any one amino acid but ref...

Information on different rangeland plants’ nutritive values during variousphonological stages is of importance for the rangelands management. This information helpsrangeland managers to choose proper grazing times to achieve higher animal performancewith no detrimental effects on the rangeland vegetations. Effects of various plant parts’phenological stages and vegetation types on reserve carboh...

The importance of sugar as the principal dietary substrate that drives the caries process has led to growing interest in sugar substitutes. Dynamic relation exists between sugars and oral health. Dental profession shares an interest in the search for safe, palatable sugar substitutes to prevent dental caries and have attempted to persuade their patients to adopt special dietary programs to limi...

on three lines?(1) the measurement of the physical indices of the nutritional conditions of the people, (2) the measurement of the prevalence of deficiency diseases, and (3) the estimation of the food values (mainly protein, mineral and vitamin values) of the diets as indicated by their daily or monthly purchases of raw food materials. The deficiencies so ascertained have been sought to be reme...

Sweeteners are divided by their sources into natural and synthetic and by their nutritional values into nutritive and non-nutritive. Xylitol is a five carbon natural sweetener found in fibrous vegetables and fruit, which offers many health benefits to human. On oral health xylitol prevents dental caries, retards demineralization of tooth enamel, promotes remineralization of tooth enamel, increa...

this study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, rubia tinctorum l.  and alfalfa medicago sativa. using in vitro and in situ measurements. the mean values for om, cp, ndf, adf and ee were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg dm for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg dm for alfalfa hay, respectiv...

Purpose: To verify the influence of preterm infants’ behavioral states in non-nutritive sucking, nutritive sucking and feeding performance at the moment of oral feeding release. Methods: Thirty-two preterm infants participated in the study. They were hospitalized in a Neonatal Intensive Care Unit and presented stable clinical conditions. After medical release for oral feeding, the following asp...

Alternative phenotypes are discrete phenotypic differences that develop in response to both genetic and environmental cues. Nutritive embryos, which arrest their development to serve as nutrition for their viable siblings, are an example of an alternative developmental phenotype found in many animal groups. Females of the marine snail, Crepidula navicella, produce broods that consist mainly of ...

In the first paper of this series (Thomson, 1958) I described a survey of the diets of 489 primigravidae living in Aberdeen during the years 1950-3. A straightforward comparison of the nutritive value of the diets with ‘recommended allowances ’ for pregnant women showed that many of the diets were substandard, but a more detailed analysis (Thomson, 1959a) led to the conclusion that they were no...

The great importance of legume hay is recognized by everyone interested in livestock production. Because of this importance, it is highly desirable to obtain data on the nutritive value of the proteins in these hays when they are fed alone and when fed in combination with the protein of corn and other farm-grown grains. It is apparent that the great value of legume hays in stock feeding is larg...
