in a 2  3  2 factorial arrangement, 144, fifty–four-week-old laying hens, in 12 treatments with 12 replicates for each treatment, received one of 12 diets based on maize or wheat containing three levels of dried tomato pomace (dtp: 0, 50 and 100 g/kg) as a substitute for wheat bran, and two levels of pigment (0 and 900 mg/kg), for 9 weeks. weight gain (wg), egg production (ep), egg weight (ew...

colour is one of the most important quality factors that can influence and determine the shelf life of canned chicken kebab. colour change is considered as unsuitable distasteful to consumers, indicating the end of a product's shelf life. in this study quality aspects of samples were examined over one month intervals after being prepared and while being stored under accelerated (44 °c) con...

This study investigates the influence of some chemical additives such as methanol, ethanol, sodium oleat, chloroform and sodium hexametaphosphate (SHMP) on the dry fine grinding of calcite (X50= 33 µm) using a stirred media mill. The experiments were carried out by a batch operation, and the change in colour properties (Ry, whiteness and yellowness) of calcite powder. The results showed that th...

Food Sci., 29: 212–218. A few selected methods of the meat colour change determination were compared with regard to their usefulness in the assessment of the quality of minced pork. The study was carried ou...

the study evaluated the body weight during growth (bwg), body weight at slaughter (bws), breast meat yield (bmyg), percent breast meat yield (bmy) and breast meat quality (colour and drip loss) of genetically featherless (scsc) broilers compared to their feathered sibs under hot conditions. two hundred featherless chicks and 200 feathered sibs were reared under hot conditions in two rooms (aver...

The goals of this research were to estimate the phenotypic relationship among various breat meat quality traits, blood parameters and tonic immobility from a broiler and to describe the relation among these variables. Broiler chicks were devided into different groups: (1) colour clothing groups represented four different colours as red, blue, green, and gray and (2) the chicks that were subject...

this study describes the effects of different stocking densities on texture/colour characteristics, protein content /amino acid and lipid content/fatty acid composition of rainbow trout fillet.stocking density was selected 5 (group a), 15 (group b), 25 (group c) kg fish m−3.tukey’s multiple comparison test showed insignificant differences between measured size/weight measurement and condition fac...

http://dx.doi.org/10.1016/j.anbehav.2014.12.016 0003-3472/© 2014 The Association for the Study of A Foraging decisions can be influenced by innate biases, previous individual experience and social information acquired from conspecifics. We examined how these factors interact to affect flower colour preference in the large earth bumblebee, Bombus terrestris dalmatinus. Individual bees with no ex...

The quality of several colour image difference metrics, pixelwise CIELAB DEab, S-CIELAB, iCAM, Structural Similarity Index, Universal Image Quality and the hue-angle algorithm, have been investigated. These results were compared with the results from a psychophysical experiment in which the perceptual image difference was evaluated. Six original images were reproduced using six different colour...
