A long standing question in range management concerns the relative importance of the stocking rate versus the length of time during which animals graze a particular rangeland. We address this question by analyzing the problem faced by a private rancher who wishes to minimize the long run expected net unit cost from range operations by choosing either the stocking rate or the length of time duri...

The influence of two different stocking densities (0.20 m2/animal and 0.40 m2/animal) in transit under the hot, humid tropical conditions on heat shock protein (hsp) 70 induction was investigated in 60 Boer does. The animals were road transported for 3 h and the control group was kept under normal conditions in the farm. Irrespective of stocking density, transportation significantly increased h...

This study considers a general class of twodimensional, discrete population models where each per capita transition function (fitness) depends on a linear combination of the densities of the interacting populations. The fitness functions are either monotone decreasing functions (pioneer fitnesses) or one-humped functions (climax fitnesses). Conditions are derived which guarantee that an equilib...

and Implications Forage mass and nutritional quality were measured in the total forage monthly from May through September and in live forage in the upper half of the sward in June and August and related to body weights, body condition scores and daily methane emissions in pastures grazed at a stocking rate of 1.98 cows per hectare by continuous, rotational or strip-stocking at a limited forage ...

To examine the long term e ects of fertiliser application on pasture growth under grazing a mathematical representation of the pasture ecosystem is created and analysed mathe matically From this the nutrient application level needed to maintain a given stocking rate can be determined along with its pro tability Feasible stocking levels and fertiliser application rates are investigated and the o...

Background: There are a few studies that evaluate preparedness and availability of antidotes in the emergency setting and none have been conducted in Qatar. Published studies show that timely availability of antidotes in the emergency department setting is a common issue. To address this, we conducted a study to evaluate antidote stocking and utilization in Qatar hospital pharmacies and emergen...

A grazing trial compared the effect of stocking rate on corn residue removal and nutrient quality over a 55 d period. Treatments included no removal (control), light grazing (2.5 animal unit months/ha), heavy grazing (4.9 animal unit months/ha), and baling (bale), that were applied to eight 6.6 ha paddocks (2 replications) on a 53 ha center pivot irrigated field of corn residue from mid-Decembe...

INTRODUCTION Vegetation and livestock responses from a 25 year (1982-2006) grazing system and stocking rate study in the northern mixed-grass prairie at the USDA-Agricultural Research Service, High Plains Grasslands Research Station near Cheyenne, Wyoming are presented here. This study was longest known grazing system X stocking rate study in North America and was one of the few studies to use ...

The biological and anthropogenic (management) factors that may contribute to the expansion of non-native lineages in managed fish have been studied in this work taking brown trout (Salmo trutta) as a model species. The changes of users' opinion about stocking was studied employing social science methodology (surveys). The evolution of hatchery stocks together with the outcome of stocking were a...
