In this study, four different biodiesel fuels obtained from corn oil, safflower-rapeseed oil mixture (50%-50% v/v), waste chicken fat, and fleshing were tested in a six-cylinder, water-cooled, TDI diesel engine. Vegetable animal fat origin fuels’ effects on the performance, injection, combustion emission characteristics of test engine compared with each other petroleum-based fuel as reference f...

OBJECTIVE Fast foods are often energy dense and offered in large serving sizes. Observational data have linked the consumption of fast foods to an increased risk of obesity and related diseases. DESIGN We surveyed the reported energy, total fat and saturated fat contents, and serving sizes, of fast-food items from five major chains across ten countries, comparing product categories as well as...

The effect of in ovo administration of antiadipocyte monoclonal antibodies (MAb) on growth and adipose tissue development in chickens was investigated. In Trial 1, 60 fertilized eggs from layer-type chickens were injected into allantoic circulation with different amounts of MAb against chicken adipocyte plasma membranes (0, 0.05, 0.1, 0.2, and 0.4 mg) on Day 15 of embryogenesis. In Trial 2, 180...

Major objectives of the poultry industry are to increase meat production and to reduce carcass fatness, mainly abdominal fat. Information on growth performance and carcass composition are important for the selection of leaner meat chickens. To enhance our understanding of the genetic architecture underlying the chemical composition of chicken carcasses, an F(2) population developed from a broil...

A radial basis function neural network (RBFN) approach was used to develop a multi-input, multi-output model for the effect of diets varying in the percentage of ME provided by protein (% ME(P)), fat (% ME(F)), and carbohydrate (% ME(C)) on live weight gain, protein gain, and fat gain in growing chickens. Thirty-three data lines representing response of the White Leghorn male chickens during 23...

production of chicken meat is an important branch of food industry. generally, poultry meat farmers aim to produce birds with superior body weight and feed conversion ratio. however, in line with current developments, there are other parameters that must to be taken into account such as lower body fat deposition and improvement in the nutrient composition of products corresponding to consumer r...

We studied the influence of dietary fat source and dl-α-tocopheryl acetate and ascorbic acid supplementation on the sensory quality of cooked dark chicken meat stored at −20 C for different periods. Results showed that dietary fat source and α-tocopheryl acetate supplementation influenced sensory scores (rancid flavor and aroma and acceptability). Ascorbic acid had no influence on these scores....

This paper described a fast, simple, and small scale method of sample preparation followed by High-Performance Liquid Chromatography (HPLC) coupled Photo-Diode Array (PDA) detector for quantification of canthaxanthin in chicken liver and fat, and hen’s egg yolk. The HPLC-PDA was performed on a C18 column with an isocratic mobile phase. Analyte was extracted from the sample using a handheld ultr...

The feed restriction program is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken. Quantities and qualitative feed restriction are procedures that can be used to manipulate the feeding strategies of poultry in order to decrease growth and metabolic rate to some extent and so alleviate the incidence of some metabolic diseases such as a...
