Stocking rate effects on intensive-early stocked Kansas Flint Hills range were studied from 1982 tbrougb 1987. Rates were 2X, 2.5X, and 3X normal season-long stocking rates for 200-225 kg steers. Study design was a randomized complete block witb 2 replicates. Grass and forb standing crop (kg/ha) were estimated at the time of livestock removal (mid July) and again in early October. Plant bas81 c...

The present study investigated the interaction of stocking density and cool perch availability on broiler chickens raised at high ambient temperature (>30.8°C). Behavior, live performance, and the incidence of footpad and hock burns and abdominal plumage damage were investigated over a 4-wk experimental period. A total of 1,152 one-day-old Arbor Acres chicks were subjected to a 2 (cool perches)...

Increased stocking densities are frequently reported to depress chicken growth performance, but the mechanisms behind this are not fully understood. This study was conducted to investigate the effects of stocking density on growth performance and digestive microbiota, known to be sensitive to environmental factors. Chickens were reared at 2 stocking densities, 12 or 17 birds/m(2). Growth perfor...

BAKER, P. J. & SCOWCROFT, P. G. 2005. Stocking guidelines for the endemic Hawaiian hardwood, Acacia koa. Stocking relationships are an important tool for foresters because they provide a means for evaluating how effectively the trees in a stand use available growing space. While stocking guidelines are not available for many tropical tree species, readily obtained measurements of stem and crown...

BACKGROUND Inadequate hospital stocking and the unavailability of essential antidotes is a worldwide problem with potentially disastrous repercussions for poisoned patients. Research indicates minimal progress has been made in the resolution of this issue in both urban and rural hospitals. In response to this issue the British Columbia Drug and Poison Information Centre developed provincial ant...

this experiment was conducted to determine the effects of sodium bentonite litter supplement and stoking density on performance and litter quality using a total of 252 broiler chicks in completely randomized design with 6 treatments which were arranged factorially (3×2) and 4 replicates. experimental factors included: stocking density (14; low and 18; high /birds per m2) and three levels of sod...

There has been little examination of the relationship between the stocking of live trees in forests and the associated attributes of dead tree resources which could inform large-scale efforts to estimate and manage deadwood resources. The goal of this study was to examine the relationships between the stocking of standing live trees and attributes of standing dead and downed dead trees using a ...

The stocking of hatchery-produced whitefish is a common practice in most countries of the species' natural range. Rigorous monitoring of the effects of stocking is less common , however, and possible negative impacts of stocking ontlle target population are rarely considered, even though supportive stocking might exelt a series of negative effects. The present study discusses Ulese potentiiLl i...

To evaluate effects of stocking density on welfare of Amur sturgeon (Acipenser schrenckii), an experiment was designed using three initial stocking densities in flow-through tanks (LSD = 3.7 kg m , MSD = 6.9 kg m , and HSD = 9.3 kg m , respectively) for 60 days. Growth, body composition, and haematological and biochemical parameters were monitored. The mortality and feed conversion rate (FCR) w...
