The chemical composition and protein quality of 11 alternative protein sources (chicken products, blood products, enzyme-hydrolyzed fish protein concentrate, soybean meal, and spray-dried pork liver) were determined, and an experiment was conducted to determine palatability and digestibility of processed red blood cell-containing diets. Chicken protein sources differed in concentrations of CP, ...

The intent, in this manuscript, is to characterise the United States Department of Agriculture (USDA) andMeat Standards Australia (MSA) systems for assessing beef quality and to describe the research evidence that supports the principles involved in grade application. USDA beef quality grading standards rely on carcass-trait-only assessments of approximate ageof theanimal at harvest andamount o...

An experiment was conducted to investigate pig performance, carcass quality, and palatability of pork from pigs fed distillers dried grains with solubles (DDGS), high-protein distillers dried grains (HPDDG), and corn germ. Eighty-four pigs (initial BW, 22 +/- 1.7 kg) were allotted to 7 dietary treatments with 6 replicates per treatment and 2 pigs per pen. Diets were fed for 114 d in a 3-phase p...

Experiments were performed to study the effect of measurement duration on palatability of eleven range species and to define thereafter a palatability index. The range species were randomly distributed in five combinations (C l to C5) containing each four species. Each combination was tested over a15-day experimental period on four one-year old sheep and five two-year old one-humped camels (cam...

Food palatability acts on the dopaminergic reward system to override homeostatic control; however, whether postingestive calorie load in the absence of taste affects this system remains unclear. In this issue of Neuron, de Araujo et al. show that mice lacking functional "sweet" taste receptors (trpm5-/-) develop a preference for sucrose by activating the mesolimbic dopamine-accumbal pathway, so...

The palatability of various organs (body wall, cuvierian gland, viscera, longitudinal muscle bands and gonads) of sea cucumber Holothuria leucospilota (Brandt) was studied by feeding experiments, performed on a freshwater fish Sarotherodon mossambicus and a marine fish Theraponjarbua. The result shows that the food pellets of the body wall were less toxic and more palatable than the gonads, vis...

It has been hypothesized that brain development during adolescence perturbs reward processing in a way that may ultimately contribute to the risky decision making associated with this stage of life, particularly in young males. To investigate potential reward dysfunction during adolescence, Experiment 1 examined palatable fluid intake in rats as a function of age and sex. During a series of twi...
