Livestock Inventory Estimates

The January 1, 2016 Canadian livestock inventory estimates were released by Statistics Canada and Jason Wood, provincial livestock market analyst with Alberta Agriculture and Forestry says there were marginal changes and few surprises.
 
“Due to lower domestic slaughter and exports, inventory estimates reported a marginal increase in Canadian cattle. In Alberta, total cattle inventories saw a 0.4 per cent increase, while hogs increased 1.7 per cent in numbers. Conversely, Alberta sheep decreased 6.9 per cent from the previous year as farmers reduced herds” says Wood.
 
Beef replacement heifers were up 4.0 per cent on a national scale, and comparatively in Alberta at 5.2 per cent. 
 
“Alberta had the strongest retention of beef replacement heifers, followed by Saskatchewan and Manitoba.” Nationally, calf inventories increased 0.9 per cent to 3.8 million, while feeder heifers and steers dropped 1.2 per cent and 0.7 per cent, respectively. 
 
Hogs inventories were up in Canada and Alberta from January 1, 2015 due to sow and gilt retention and increasing litter rates (which in turn increases supplies for slaughter and exports). Domestic slaughter increased 4.2 per cent from 2014, and exports were up 16.4 per cent during the same period.

Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Video: Swine Industry Advances: Biodigesters Lower Emissions and Increase Profits

Analysis of greenhouse gas (GHG emissions) in the Canadian swine sector found that CH4 emissions from manure were the largest contributor to the overall emissions, followed by emissions from energy use and crop production.

This innovative project, "Improving Swine Manure-Digestate Management Practices Towards Carbon Neutrality With Net Zero Emission Concepts," from Dr. Rajinikanth Rajagopal, under Swine Cluster 4, seeks to develop strategies to mitigate greenhouse gas emissions.

While the management of manure can be very demanding and expensive for swine operations, it can also be viewed as an opportunity for GHG mitigation, as manure storage is an emission source built and managed by swine producers. Moreover, the majority of CH4 emissions from manure occur during a short period of time in the summer, which can potentially be mitigated with targeted intervention.

In tandem with understanding baseline emissions, Dr. Rajagopal's work focuses on evaluating emission mitigation options. Manure additives have the potential of reducing manure methane emissions. Additives can be deployed relatively quickly, enabling near-term emission reductions while biodigesters are being built. Furthermore, additives can be a long-term solution at farms where biogas is not feasible (e.g., when it’s too far from a central digester). Similarly, after biodigestion, additives can also be used to further reduce emissions from storage to minimize the carbon intensity of the bioenergy.
