Two experiments were conducted during a growout of male and female white pheasants to evaluate brooding space needed the first 6 wk and appropriate phase feeding strategies in the growing-finishing stages of growth. One-day-old chicks were placed into brooder pens with stocking rates of 150, 200 or 250 chicks/pen. Individual body weight and feed conversions for each pen were measured at 3 and 6...

Data on ammonia (NH3) emissions from pullets (hens <18 weeks of>age) are non-existent despite the large differences in nutritional and environmental conditions between raising pullets and laying hens. Different stocking densities (SDs) in housing the birds may be used according to certain industry guidelines on production; however, information concerning the impact of SD on properties of accumu...

A field study was conducted to evaluate the influence of some pre-slaughter factors as journey time, stocking density, and lairage time on mortality, live weight loss and carcass defects on 321 flocks of broiler chickens slaughtered at a commercial processing plant. For each flock, the following traits were evaluated: birds dead-on-arrival (DOA); live weight loss; condemned carcasses; downgrade...

this research represents the first attempt in italy to develop a cage system for adult freshwater mussel stocking, for extensive farming, that was realized from 2003 to 2005 in nw italy. two autochthonous species of italian freshwater mussel were used: anodonta anatina and unio mancus. 5133 mussels were collected and successively stocked in floating cages in 5 different sites in a lake. this st...

Application of organophosphorus (OP) insecticides to agricultural fields during the spring often overlaps the period of spawning, egg incubation, and larval stages of fish species such as walleye (Stizostedion vitreum). Because life stage can affect uptake, distribution, and effects of contaminants, our objective was to identify the most sensitive life stage of walleye tochlorpyrifos, a broad-s...

Animal welfare has generated concerns from both domestic and global market sectors. In growout, stocking density has been regarded as an area of interest for food retailers and wholesalers with welfare audits. This study examined four stocking densities on responses of male broilers during a 49d production cycle. Two trials were conducted and results were pooled. In each trial, 1,488 male chick...

Abstract North American fisheries management agencies commit considerable resources to managing reservoir for Channel Catfish Ictalurus punctatus , which often includes stocking. However, population characteristics vary greatly among reservoirs, resulting in variable and unpredictable fishery quality. We sampled populations 44 Ohio reservoirs with tandem, baited hoop nets understand relationshi...

Adaptations to salinity are reviewed throughout development in both species of the genus Homarus. Some populations of homarid lobsters are known to inhabit coastal and estuarine areas where salinity fluctuates. Salinity tolerance varies during development, with 50 % lethal salinities (LS(50)) ranging from approximately 15-17 in larvae to approximately 12 in postlarvae and 10 in adults. La...
