Forage Allowance and Daily Gain Relationships on Rye-Ryegrass Pastures at Different Stocking Rates with Continuous and Rotational Stocking

XXV International Grassland Congress (IGC 2023), 2023
‘Maton’ cereal rye (Secale cereale L.) and ‘TAM-90’ annual ryegrass (Lolium multiflorum Lam.) are used for winter annual pastures to background stocker cattle in the southeastern US. Rye and ryegrass were sod-seeded into bermudagrass [Cynodon dactylon (L.) Pers.] pastures and fixed-stocked at different rates under continuous and 8-paddock rotation ...

A comparison of continuous and rotational grazing on veld at two stocking rates

Journal of the Grassland Society of Southern Africa, 1991
Two rotational grazing procedures, a four-paddock system with a 10-day period of stay and an eight-paddock system with a 5-day period of stay, were compared with continuous grazing on veld. The trial was conducted 40 km south of Bulawayo in Zimbabwe, over the six-year period 1975-81.

Cutting Stock with Rotation: Packing Square Items into Square Bins

2020
In the square packing problem, the goal is to place a multi-set of square-items of various sizes into a minimum number of square-bins of equal size. Items are assumed to have various side-lengths of at most 1, and bins have uniform side-length 1. Despite being studied previously, the existing models for the problem do not allow rotation of items.

A Comparison between rotational grazing and set stocking with ewes and lambs at three stocking rates

Animal Science, 1975
SUMMARYIn 1972 a comparison was made between rotational creep grazing (R—8 paddocks) and set stocking (S—2 paddocks) for ewes and their twin lambs at 3 stocking rates viz. 20 (H), 17 (M) and 14 (L) ewes/ha.The herbage intakes/kg live weight of the R ewes were similar to those of the S ewes in period 1 (c. 7th week of lactation) but higher i n period 2 (

Stock Selection, Style Rotation

Journal of Empirical Finance, 2002
Using US data from June 1984 to July 1999, we show that the impact of firm-specific characteristics like size and book-to-price on future excess stock returns varies considerably over time. The impact can be either positive or negative at different times. This time variation is partially predictable.

Mathematical optimization of rolling stock rotations

2017
We show how to optimize rolling stock rotations that are required for the operation of a passenger timetable. The underlying mathematical ptimization problem is called rolling stock rotation problem (RSRP) and the leitmotiv of the thesis is RotOR, i.e., a highly integrated optimization algorithm for the RSRP. RotOR is used by DB Fernverkehr AG (DBF) in

The study of style rotation in chinese stock market

Proceedings of the 3rd International Conference on Business and Information Management, 2019
Many academic studies on stock markets provide evidence of style rotation and methods of style investing. However, most of the researches are based on U.S. Domestic equity mutual funds. In this paper, we present that the existence of this phenomenon in Chinese stock markets and propose a new index, named stock market characteristics index (SMCI) to ...

Setting safety stocks for stable rotation cycle schedules

International Journal of Production Economics, 2014
Abstract In the process industries, specialized equipment and production processes often necessitate the manufacture of products in a pre-determined sequence to minimize changeover time and to simplify scheduling complexity; these types of schedules are referred to as pure rotation schedules, or product wheels, where the circumference of the wheel is

Optimal Stocking Levels and Rotation Under Uncertainty

Forest Science, 1984
Abstract Decision making under uncertainty involves making decisions in situations where there is no information concerning future events. To resolve this problem in optimal stocking control when the growth function of a species is initially unavailable and the decision maker is risk neutral, adaptive optimization can be used which ...

Optimal Stocking Levels and Rotation Under Risk

Forest Science, 1982
Abstract The usual joint optimization of stocking levels and rotation length discussed under the deterministic assumption is generalized to probabilistic cases. A probabilistic dynamic programming model is constructed to resolve the difficulties introduced. Every value in the deterministic model is replaced by an expected value in the
