Previous studies show that children who are sensitive to the bitter taste of 6-n-propylthiouracil (PROP) report more frequent intake of sweets and less frequent intake of meats (savory fats) relative to children who are PROP insensitive. Laboratory studies are needed to confirm these findings. In this study, seventy-nine 4- to 6-year-olds from diverse(More)
A Probabilistic Neural Network (PNN) was trained to predict ascites in broilers based on minimally invasive inputs (i.e., physiological factors that do not require the death of the bird). A PNN is a supervised, three-layer, artificial neural network that classifies input patterns (e.g., physiological data) into specific output categories (e.g., ascites or(More)
An artificial neural network was trained to predict the presence or absence of ascites in broiler chickens. The neural network was a three-layer back-propagation neural network with an input layer of 15 neurons (defining 15 physiological variables), a hidden layer of 16 neurons, and an output layer of 2 neurons (the presence or absence of ascites). Male(More)
The influence of population density on the growth performance and stress level of Hubbard x Hubbard chicks of equally mixed sex was studied. Six hundred and sixteen birds were housed under .05, .07, .09, or .11 m2 per bird (four replicates per density) from 0 to 7 wk. There were no treatment effects on feed conversion at 6 or 7 wk. Birds housed at .07, .09,(More)
A system was designed to facilitate the chronic infusion and/or serial blood sampling of rapidly growing, meat-type chickens with little or no stress to the bird. Techniques for surgically preparing an indwelling catheter, fabricating a harness system to protect this catheter, utilizing a miniature fluid swivel to provide free movement and infusing(More)
A replicated experiment (two, 1-yr trials) was conducted to define colony size and cage space requirements of laying hens. DeKalb XL pullets, 19 wk of age, were randomly assigned to cages sized 1548, 3097, and 4645 cm2 at population densities of 2, 3, 4, or 5 hens. Membership values for fuzzy decision analysis were related to the performance of birds as(More)

have that luxury in commercial fl ocks, and in extreme situations, this leads to unintentional feed restriction. It is very unusual for young broilers to be intentionally feed restricted, although very short day lengths — a practice that was common 10 years ago to combat ascites — had this intentional effect. Likewise, limiting feed intake of birds as early(More)
Daily BW velocity (BWV) and acceleration (BWA) of individual birds have been demonstrated to be oscillatory. Daily feed intake velocity (FIV) and acceleration (FIA) were hypothesized to be oscillatory and to have a positive relationship with BWV and BWA, respectively. Forty-eight male broiler chicks were individually caged and provided a commercial starter(More)
