The effects of dietary forage, social hierarchy, and stocking density on stress in lactating cows during relocation
… effects of forage fiber, social hierarchy, and stocking density on stress in lactating cows during relocation to new dairy facilities. In experiment one, 23 lactating cows were fed a basal ration, or the basal ration plus grass or alfalfa hay at 10% of DM offered from 3 wk pre-move to 9 wk …

Rainbow Trout Cage Culture and Benthic Production in East-Central South Dakota Dugouts
… feasibility of raising annual fish crops. Growth rates were compared between feeding rate (0, 3, and 5% body weight/day [bwt/day]) and stocking rate (35, 52, and 70 fish/cage). Growth was significantly (P ≤0.05) greater at feeding rates of 3 and 5% bwt/day than 0% bwt/day. The fish fed 0% bwt/day …

Mob stocking effects on herbage nutritive value, herbage accumulation, and plant species composition
Mob stocking is a variation of rotational stocking known for restricting a large number of animals to a small area before being moved to new grass after a few hours. This method allows a long (90-day) recovery period but was hypothesized to diminish the nutritional value of herbage relative to …

Evaluation of quickstand bermudagrass fertilized with two rates of nitrogen and grazed by sheep at different stocking rates in a temperate environment
… (Cynodon dactylon [L.] Pers.) in a cool temperate environment. Four stocking rates and two N fertilization rates (4 x 2 factorial) were replicated three times on .11-ha paddocks. Paddocks were continuously stocked with two, four, six, or eight lambs (light, moderate, heavy, and very heavy …

A systems approach to the economic evaluation of nitrogen fertiliser use in sheep farming enterprises
… which is used iteratively, to determine the stocking rate, stock performance, seasonal pasture production using nitrogen fertiliser and inter-seasonal feed transfer policies in order to, maximise net farm income. The Cornforth-Sinclair phosphate model and the U.K. Agricultural Research …

Next generation dairy systems for Canterbury: A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science with Honours at Lincoln University
… foot print. The two systems where High Stocking rate Efficient (HSE) (5 cows/ha) and Low Stocking rate Efficient (LSE) (3.5 cow/ha). HSE recorded high production per hectare for both milksolids and pasture production (2369 kgMS/ha & 19417 kgDM/ha) pasture quality was also high (11.8 …

Assessment of vegetation diversity and rangeland condition in the Highveld communal grazing lands of Swaziland
Determination of correct stocking rate based on current rangeland condition still remains a big challenge to livestock farmers. Assessment of vegetation diversity and current rangeland condition was carried out in four communal rangelands, namely Siphocosini, Hawane, Motshane and Nkhaba. The …

An analysis of lambing ewes three times in two years in Southland
… critical feeding period, thus determining the stocking rate. The conventional system wintered 19.4 SU/ha under all grass and hay wintering. However the use of a high yielding winter feed crop was necessary to maintain a stocking rate of 13.6 SU/ha through winter for a multiple lambing system. …

Modelling New Zealand dairy farm systems to design greenhouse gas mitigation strategies
… the cost-effectiveness of diverse mitigation strategies for reducing GHG loads between 10–30% within systems of different production intensity in the main dairy farming regions of New Zealand: Waikato and Canterbury. Pastoral dairy farms, as found in New Zealand, are complex farming systems with …

Food Habits and Growth of Rainbow Trout in a Prairie Pond
… into Lower Abbey Pond, South Dakota, at a stocking rate of 772/ha in June 1977. Sampling was begun in January 1978 to determine food habits and growth of the fish. Trout and environmental samples were taken at 10 day or monthly intervals depending upon the season. A linear index of food …

Rainbow Trout Production and Water Quality in Eastern South Dakota Dugouts
… Trout growth was compared between dugouts by stocking rate (1977/ha, 1483/ha, 988/ha, and 494/ha) and feeding combination [fathead minnows (Pimephales promelas) and supplemental feed, supplmental feed, and trout alone]. Chemical physical properties were also monitored in an old and new …

Stocking Density, Strain Performance, and Feeding Method Evaluation of Cage Reared Rainbow Trout (Salmo gairdneri) in Eastern South Dakota
… landowners for personal consumption. Maximum stocking density (fish/m3) was not determined. Densities greater than those used would have been needed to determine the optimum stocking rate. The use of a deeper culture cage (3 m) was justified in this area due to the high water temperatures that …

The Influence of Grazing Treatments on Density of Nesting Burrowing Owls on the Cheyenne River Sioux Reservation
… from 9.3 ha to 160.1 ha. The average year-long stocking rate for each study site was 10.7 hectares/animal unit. I sampled burrowing owl densities, prairie dog activity (inactive and active burrow density) and town size for each study site in 2004 and 2005. There was a significant difference in …
