Livestock Manure Storage
Posted in: Environment by admin on January 1, 2004 | No Comments
Specific government regulations are in place for th construction and the operation of manure storage structures. Producers must be capable of storing livestock manure until it can be applied to crop land. This fact sheet serves to answer basic question people may have regrading the development of intensive hog facilities. Why is Manure Stored? What are the environmental concerns about manure storage? What about odour from stored manure? How is Manure stored? Are there specific reuirements for manure storage? How big must liquid manure storage structure be? Are manure storage structures inspected? Livestock manure can be managed in an environmentally sound manner. By storing manure the farmer can use as fertilizer as the most appropriate and effective time in the crop production cycle. When constructed in accodance with regulation, inspected annually and operated with care, manure storage structures provide environmental proection during the expected life time of the operation.

On-farm comparison of incinerators for dead animal
Posted in: Environment by admin on | No Comments
The recent increase in cost of dead stock collection services on the farm has made incineration become an interesting alternative. Three manufacturers of Québec’s province designed on-farm incinerators and had them evaluated under the instigation of the FPPQ (Québec’s Pork Producers’ Federation). The three incinerators assayed in this campaign were the Brûle-Ô-Max, Éco-Concept and Max-Flame apparatus. According to the assay, these three models showed, respectively: a capacity of 454kg, 454kg and 350kg, an average loading rate (relatively to their maximum capacity) of 83%, 86% and 91%, a cycle duration of 6h20min, 6h18min and 5h09min, an incineration rate of 63,6kg/h, 62,6kg/h and 41,2kg/h, and a propane consumption rate of 0,17, 0,16 and 0,40 liter of propane per kilogram of dead stock. All three incinerators had the two combustion chambers and the particle emission rate required by Québec’s regulations, did not emit any smoke or odours during incineration and maintained a temperature of 1000°C in the gas combustion chamber (where the residence time was around one second). The ashes produced represented 3 to 4% of the incinerated material’s mass. Fissuring of the firebricks and airtightness problems were noted on the Éco-Concept and Brûle-Ô-Max incinerators, which would require monitoring of the inner covering durability. Considering the building of a shelter, the addition of a temperature recorder and performing an atmospheric emission test every five years, the incineration costs varied from $0,14/kg to $0,25/kg for a farrow-to-finish farm with 600 sows, to over $1,00/kg for a finisher pig farm of 1000 pigs.

Managing Livestock Mortalities
Posted in: Environment by admin on | No Comments
Mortalities occur sooner or later in all livestock production. Becuae of the relative numbers involved, large scale operations will have more dead animals requiring disposal than smaller frms. Mortality tends to be greater among some types of livestock such as poultry than other types such as beef cattle. Mass mortality may occur in livestock confined in structures such as barns but less likely to occur among livestock on the range. The regulation requires that mortalities be stored in a secure manner. Mortalities must be stored in a frozen state or kept refridgerated if they cannot be disposed of within 48 hours of death. Many intensive livestock operations have a separate freezer or refridgerated storage for this purpose. Producers who are able to dispose of mortalities within 48 hours of death rely on specially designed, covered steel or heavy duty plastic bins for secure storage.
