two experiments were conducted to determine lysine (lys) requirements of two commercial strains, ross 308 and cobb 500, from 15 to 28d of age. basal diet was formulated to be adequate in all nutrients except for lys. incremental levels of supplemental lys were added to the basal diet generating six experimental treatments in a range from 0.60 to 1.20% digestible lys. birds were randomized acros...

Background A number of commercial diet and exercise programs are promoted to help people lose weight and improve fitness. However, few studies have compared the effects of following different types of exercise and diet interventions on weight loss. The purpose of this study was to compare the efficacy of a more structured meal plan based diet intervention and supervised exercise program that in...

Weight-loss diets restrict intakes of energy and macronutrients but overlook micronutrient profiles. Commercial diet plans may provide insufficient micronutrients. We analyzed nutrient profiles of three plans and compared their micronutrient sufficiency to Dietary Reference Intakes (DRIs) for male U.S. adults. Hypocaloric vegan (Eat to Live-Vegan, Aggressive Weight Loss; ETL-VAWL), high-animal-...

Objective 1. Identify diet formulations to improve reproductive performance (egg biochemical composition, fecundity, egg and fry quality) of catfish and determine associated effects on production costs. a. Manipulate dietary protein concentration and lipid sources and assess reproductive performance and diet effects on production costs (Tank Trial 1). b. Refine dietary protein and lipid sources...

The present study was carried out to evaluate the effects of thymol and carvacrol supplementation on performance, immune response, antioxidant enzyme activity and blood parameters of heat stressed broilers. Broilers were fed with commercial diet till 25 d of age, then they were allocated to a completely randomized design with a 3 × 2 factorial arrangement with 6 treatments including 3 levels of...

Taurine (Tau) deficiencies have been associated with the feeding of commercial lamb-meal and rice diets to dogs. We hypothesized that the poor digestibility of some lamb-meals may limit sulphur amino acids availability for Tau synthesis and/or increase of Tau degradation in the gut. Growing dogs were fed either a lamb-meal-based (Diet A) or poultry by-product-based (Diet B) commercial diet. Pla...

The effect of diet on the occurrence of canine atopic dermatitis (CAD) in the high-risk breeds boxer, English bull terrier and West Highland white terrier was investigated as part of an extensive case-control study. In that study, a sparing association was seen for feeding the bitch a diet containing non-commercial ingredients during lactation and the subsequent development of CAD in the offspr...

A dog's nutrient requirements can theoretically be met from a properly balanced meat-free diet; however, proof for this is lacking. Exercise places additional demands on the body, and dogs fed a meat-free diet may be at increased risk of developing sports anaemia. We hypothesised that exercising dogs would remain in good health and not develop anaemia when fed a nutritionally balanced meat-free...

background and objectives evaluation of protein quality in food is of great importance due to the biological and economical impacts of food proteins. this study has been conducted with the aim of comparing the protein quality of homemade food (mixture of macaroni and soy bean) with commercial baby food (cerelac wheat) using casein as the refference point.   methods this study was conducted on 6...

Two experiments were conducted to study the effect of phytase supplementation to lowphosphorus starter and finisher broiler diets on mineral utilization and growth performance. All diets in this study were isonitrogenous, isocaloric and corn-soybean diets. In Experiment 1, four replicate groups of 15 commercial broiler chicks, one-day old, were randomly assigned to each of two dietary treatment...
