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 ...

We modeled the cost-effectiveness of rearing Anastrepha ludens, a major fruit fly pest currently mass reared for sterilization and release in pest control programs implementing the sterile insect technique (SIT). An optimization model was generated by combining response surface models of artificial diet cost savings with models of A. ludens pupation, pupal weight, larval development time and ad...

To avoid nutrient limitations, MP requirements are often overestimated in the formulation of dairy cow rations. Overfeeding of N results in increased expenses for producers and increased N excretion to the environment. Thus, improvements in the efficiency of dairy cow feeding provide economic and environmental incentives. Previous improvements in feed efficiency have come via the dilution of ma...

A recently developed oral formulation in the form of coated tablets (Monoselect Camellia) (MonCam) containing highly bioavailable green tea extract (GreenSelect Phytosome) was tested in obese subjects (n=100) of both genders on a hypocaloric diet. Fifty subjects were assigned to the green tea extract plus hypocaloric diet, while the other 50 subjects followed the hypocaloric diet only. After 90...

Over 350 species of birds make up the order Psittaciformes; many of these are maintained in captive environments. Malnutrition is commonly diagnosed in captive psittacine birds; therefore, providing nutritionally adequate diets must be a primary concern. This review integrates quantitative information on the dietary habits and nutritional requirements of psittacine birds to facilitate the formu...

Adding attractants can improve acceptability of artificial diets by carnivorous fish fry and fingerlings, increasing intake of unpalatable feeds and improving growth rate, while reducing feeding time and feeding wastes. This study aimed to evaluate the effects of levels of inclusion of different attractants in plant protein-based diets on the performance of largemouth bass Micropterus salmoides...

In this study, we examined the activity of two serine proteases (chymotrypsin and trypsin) and two metalloproteases (carboxypeptidases A and B) during larval development in Anastrepha obliqua fed natural (mango fruit) and artificial (formulation used in mass-rearing) diets. Proteolytic activity of chymotrypsin, trypsin, carboxypeptidase A, and carboxypeptidase B was detected in the midgut of d...

objective(s): irinotecan is a potent anti-cancer drug from camptothecin group which inhibits topoisomerase i. recently, biodegradable and biocompatible polymers such as poly lactide-co-glycolides (plga) have been considered for the preparation of nanoparticles (nps). materials and methods: in this study, irinotecan loaded plga nps were fabricated by an emulsification/solvent diffusion method to...

Abstract The present study aims at the identification and investigation of fatty acid and amino acid profiles in male and female Liza aurata in the southern part of the Caspian Sea, in reproductive (autumn) and non-reproductive (spring) seasons. The results showed difference between the total fatty acids levels in the sexes. Analyses of fatty acids indicated a higher percentage of C16:0, C...
