Managing variability in decision making in swine growing-finishing units

BACKGROUND Analysis of data collected from pig farms may be useful to understand factors affecting pig health and productive performance. However, obtaining these data and drawing conclusions from them can be done at different levels and presents several challenges. In the present study, information from 688 batches of growing-finishing (GF) pigs (average initial and final body weight of 19.1 a...

Benchmark Forecasting in Data Envelopment Analysis for Decision Making Units

Although DEA is a powerful method in evaluating DMUs, it does have some limitations. One of the limitations of this method is the result of the evaluation is based on previously data and the results are not proper for forecasting the future changes. So For this purpose, we design feedback loops for forecasting inputs and outputs through system dynamics and simulation. Then we use DEA model to f...

Effects of supplemental selenium on swine. II. Growing-finishing.

The effects of dietary selenium (Se), copper (Cu) and zinc (Zn) on growth characteristics, selected blood parameters and carcass traits in growing-finishing swine were evaluated in two experiments. In the first experiment, 48 Duroc barrows and gilts weighing approximately 30 kg were al lot ted by sex and weight to six dietary treatments. They were fed a basal 16% crude protein diet containing ....
