The aim of the present study was to assess whether near infrared reflectance spectroscopy (NIRS) and regression equations are the practical and accurate approach of nutritional assessment of common feedstuffs. Therefore two experiments were conducted to study the effect of amino acid determination methods on broiler performance. In experiment I, two hundred thirty four male Ross broiler chicks ...

INTRODUCTION There is an increasing use of enteral therapy at home, which reduces costs and improves patients' quality of life. Homemade food diets are being commonly used in the households of undeveloped countries, but those diets vary in composition and characteristics depending on the ingredients and preparation procedures adopted in its preparation, which influences the quality of the diet ...

Susceptibility to the Cry1Ac toxin from Bacillus thuringiensis in tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is usually measured by performing bioassays under laboratory conditions. Accurate comparison of Cry1Ac susceptibility among H. virescens samples conducted in different places is challenged by several important methodological aspects, especially if different insec...

Companion animal owners are increasingly concerned about the links between degenerative health conditions, farm animal welfare problems, environmental degradation, fertilizers and herbicides, climate change, and causative factors; such as animal farming and the consumption of animal products. Accordingly, many owners are increasingly interested in vegetarian diets for themselves and their compa...

This study investigates the effects of dietary lipid sources on the growth and reproductive performance of Nile tilapia over three consecutive spawnings. Fish were reared using three experimental diets, with the goal of replacing dietary fish oil with palm oil. Three experimental diets and a commercial   trout diet was used as the control. The effect of dietary lipid on the growth performance, ...

Substantial interaction was observed in 3 inbred strains of mice maintained on 5 normal commercial pelleted diets. Strain 0 to.OR was most sensitive to the unknown dietary factor, and the ranking of 0 tO.BR and A2G was reversed across the array of diets, There was no apparent relationship between the 'biological' value of the diet and 21 dietary ingredients determined chemically, The study show...

Commercial poultry operations involve four types of birds: broiler (meat producing) chickens, layer (table egg) chickens, turkeys, and ducks. Each type differs greatly in size and nutrient requirements. Breeder flocks for each of the species are a major part of the industry, and those flocks also have different nutrient requirements. Distinctly different diets are required for each species and ...
