It is beneficial for the Ontario swine industry to know how it compares relative to producers in other major swine producing regions and other Ontario commodities in terms of their debt levels and their ability to meet financial repayments should interest rates rise from their current historically low levels. As well, it is important to know how Ontario swine producers compare across different farm sizes and production types.
A tool has been developed that allows comparison with industry averages. Depending on what the comparison reveals to the producers it may encourage them to develop business rick management strategies, or seek out training and business management advice. Debt Comparison Tool
The research tests the hypothesis that the immune response (IR) of newborn pigs which is in adverse type 2 bias, can be modulated towards type 1 bias by repeated 1) intramuscular injections of killed bacteria or their molecular components or 2) oral treatments with the live bacterial probiotic Lactococcus lacits.
Determination of Optimal True Digestible Calcium (Ca) to Phosphorus (P) Ratio in Grower-Finishing Pigs for Minimizing Phosphorus Excretion
Final Report
Final Report: Effect of Tillage and Timing of Liquid Manure Application on the Transport of N, P and Bacteria to Surface and Subsurface Waters
The focus of this research was the assessment of different management practices for their ability to mitigate transport of nitrogen, phosphorus and pathogens to surface water, tile water and groundwater from land application of liquid swine manure.
In the study a controlled level of immune system stimulation (ISS) was achieved based on a repeated injection of increasing doses of inactivated microbial wall material (lipo-polysaccharides from coliform bacteria). It was shown that systemic ISS reduces the pig’s growth performance potential, but does not influence nutrient digestibility. It was demonstrated that the dietary requirements for methionine plus cysteine and for tryptophan for supporting body maintenance functions were increased during ISS. In metabolism and gene expression studies it was shown that ISS up-regulates metabolic pathways that utilize methionine and cysteine, reducing the availability of these amino acids for supporting accretion of body protein (e.g. muscle mass). Based on this research practical recommendations were made to adjust intake of these three key amino acids to optimize the pig’s response to sub-clinical levels of disease.
Development of an Integrated Mycotoxin Management System in Ontario Grains
Development of Fusarium resistant corn inbreds for pork production
The University of Guelph in conjunction with OMAFRA and Ontario Pork wish to establish baseline values for Ontario producers for pre-weaning, mortality, nursery mortality, and finisher mortality. Enrolment in this study requires simple weekly reporting of mortalities in the farrowing, nursery, and finisher areas of production. Enrolment is open to all producers regardless of farm size or type provided that weekly mortality in at least one of the 3 areas of production (farrowing, nursery, and/or finishing) can be recorded and reported weekly.
In livestock species, the sex of an animal is arguably the most important genetic trait with considerable influence on profit. Although current sperm sex-sorting methods by flow-cytometry are well established and functional, the development of sex-specific probes could improve efficiency of current methods, or allow the development of new sperm sorting strategies. Previous efforts to resolve differences in X- and Y-sperm have ultimately failed to identify any sex-specific molecular marker in sperm.
The OPIC Swine Health Advisory Board (OSHAB) has received a $25,000 grant from the Ontario Pork Producers’ Marketing Board to develop a centralized Ontario PRRSV database in collaboration with the Animal Health Laboratory (AHL), Laboratory Services Division, University of Guelph. This tool has been designed to allow comparisons of percent similarity between PPRSV isolates from farms throughout Ontario. The database is being used by Ontario swine veterinarians and producers to help in understanding viral spread, prevalence and severity of clinical signs seen with specific variants, and is facilitating improved communications between veterinarians.
In vitro-studies were conducted to assess the impact of using bacterial inoculants and enzymes on degradation of starch and phytate-phosphorus and appearance of organic acids and alcohol in high-moisture corn mixed with water in a 1 to 2 ratio. Four starter pig performance studies have been conducted at the Arkell Swine Research Station using the liquid feeding system.
A cross-sectional prevalence study was conducted, based on a convenience sample of 20 pig farms from south-western Ontario, Canada. Nasal and rectal swabs were collected from pigs of three different age groups (suckling pigs, weanling pigs and grower-finisher hogs). Whenever possible, five pigs from each age group were selected using a convenience sampling scheme that avoided sampling more than one pig in co-mingled groups.
