Earthen Manure Storage Monitoring – PSC Elstow Research Farm

Posted in: Environment by admin on | No Comments

Introduction
Rapid growth in the Saskatchewan hog industry has caused an increase in environmental awareness among the public. This had led to more
stringent environmental standards being imposed on the construction of earthen manure storages. Most storages are now required to have a minimum 600-mm thick liner made of recompacted in situ soils. More extreme cases require a geotextile liner. These recommendations have resullted in a significant improvement over the unlined and uncompacted storages constructed in the past. Unfortunately, these improved liners have done little to alleviate public concern in some areas. In answer to this concern, a program was initiated to monitor solute migration through the liners of different hog lagoon storages throughout Saskatchewan.

Objectives
The main objectives of this project are to:
1. Determine changes in groundwater chemistry with depth over time,
2. Determine effectiveness of clay liners and clarify liner requirements, and,
3. Determine safe separation distance between EMSa

LABORATORY MEASUREMENT OF HYDROGEN SULFIDE AND SULFUR DIOXIDE RELEASES FROM SWINE MANURE OF DIFFERENT SOLID CONTENTS

Posted in: Environment by admin on | No Comments

Releases rates of hydrogen sulfide (H2S) and sulfur dioxide (SO2) from finishing swine manure of two
different solid contents and two initial manure accumulation days were measured under laboratory
conditions for one month. Manure was stored in reactors of 122 cm height and 38 cm diameter. The
reactors were continuously ventilated with 7.7 L/m of fresh air. Temperature was controlled at 20 A

Characterizing and Manipulating Energy Content of Ingredients

Posted in: Prairie Swine Centre by admin on | No Comments

Characterizing the energy content of ingredients included into swine diets is important for accurate diet formulation. Methods to characterize the energy content of ingredients will be illustrated with data from large collaborative study with barley. Potential use of characterizing information for manipulating the energy content will be discussed in this presentation.
