OBJECTIVE To analyze the influence of food preparation methods on the composition of fatty acids and cholesterol in foods. METHODS The chemical composition of cholesterol and fatty acids was analyzed in eight different types of meat and feijoada in relation to different methods of preparation. RESULTS Feijoada, when prepared with the beans and meats in separate pots, has less cholesterol (1...

Chicken has been used as a suitable model for lipid metabolism studies, because dietary modifications especially dietary fat type can change chicken body composition. Fats act as a condense source of energy and certain fatty acids such as polyunsaturated fatty acids (PUFAs) are required for both animal and human health. The n-3 PUFAs, especially, eicosapentaenoic acid (EPA) and docosahexaenoic ...

A cell-free translation assay was applied for the quick detection of ricin in food samples. Three economically important foods-ground beef, low-fat milk, and liquid chicken egg--were tested. The results indicated that ground beef had very little matrix effect on the assay, whereas low-fat milk and liquid chicken egg showed clear interference on the protein translation. A simple dilution in phos...

The aim of the research was to determine live body weight, carcass percentage, and percentage abdominal fat in broiler chicken affected by herbal drinks.One hundred twenty birds DOC used research. Basal diet contain metabolizable energy 3000 kcal/kg crude protein 22%.Experimental design completely Randomized Designed with 6 treatments 4 replicates, every replicates consist five 5 birds. were as...

Ghrelin (GHRL) and its receptor (GHSR) are involved in various bioactivities. In this study, the complete cDNA and 5' flanking region of the duck GHRL (dGHRL) gene and a 3717 bp fragment of the duck GHSR (dGHSR) gene were obtained. A total of 19, 8, 43, and 48 SNPs identified in 2751, 1358, 3671, and 3567 bp of the chicken GHRL (cGHRL), chicken GHSR (cGHSR), dGHRL, and dGHSR genes, respectively...

this study aims to compare anatomies of madagascar chickens (indigenous race and starbro strain). with 8,262 individuals of either indigenous races or starbro strain chickens raised in a suburban environment, the weights of different pieces of cut as well as the live weights before slaughter were determined. results showed that breast development presents a positive linear relationship with thi...
