Increasing Creep Feed Intake by Stimulating Exploratory Behaviour using Enrichment

Multiple significant changes occur simultaneously during weaning making it a highly stressful time for piglets. Increased cortisol levels and weight loss are often noted after weaning, resulting in increased disease risk and mortality. Providing creep feed before weaning promotes solid feed intake and when consumed shows improved growth rate and better feed intake post-weaning. Many piglets fail to consume creep feed and when they do the consumption levels are often...

Impact of Calcium and Phosphorus on Sow Lameness and Sow Longevity

As sow productivity continues to improve, dietary mineral recommendations are evolving. Physiological and anatomical demands on the skeletal system are increasing so higher dietary levels of minerals like phosphorus and calcium are recommended. The modern, highly prolific sow has not had much research done on the calcium requirement needed. It may differ as milk requirements are for a larger litter now and sows may need to mobilize calcium from their...

Early Detection and Interventions for Reducing Lameness in Gestating Sows

One of the most common reasons for culling sows in lameness. Overall herd productivity, sow welfare and sow productivity can be increased if treatment and prevention of lameness is implemented. In order for sows to generate profit, they must remain in the herd for a minimum of three parities. With the move to group housing, sow mobility will be a more important issue, so options are needed to benefit the...

Investigation of Translactational Analgesia for Reducing Piglet Pain at Castration

Painful livestock procedure concern is increasing, with one of pig productions key issues being castration of piglets. Castration is done in male piglets to avoid 'boar taint' which is the development of undesirable odours that can occur in the meat of adult boars. Piglet castration is typically done without analgesic use. The main reason for this is the time and cost required to administer pain medication. A more practical and...

Dietary Omega-6 to Omega-3 Fatty Acid Ratios Affect Body Fat Mobilization During Lactation

Litter sizes have increased due to improved management practices and genetics, though pre-weaning mortality is even higher now. This may be due to sows not being able to keep up with the energy demands of the litter. Over subsequent parities, loss of body condition and severe negative energy balance have negative impacts on rebreeding performance and may lead to early culling. The ability to mobilize body fat can be done...

Evaluation of Heat Exchanger, Ground Source Heat Pump, and Conventional Heating Systems

A production cost that can be further reduced is energy cost. This can be done by reducing overall energy consumption or using energy more efficiently. Space heating is an area of interest for energy reduction. The performance of a heat recovery ventilator, a conventional heating system and a ground source heat pump in grow-finish rooms were evaluated over several seasons. Compared to the conventional heater, the heat exchanger and ground...

Comparative Evaluation of the Use of Heat Exchanger, Ground Source Heat Pump and Conventional Heating Systems in Grow-Finish Rooms

Profitability of swine production will be improved with any measure that reduces production cost. Using energy efficiently will help reduce the cost of energy. This can be done in the area of space heating. Energy consumption, in barn environment and animal productivity were observed when using different space heating options. Compared to the conventional heater, the heat exchanger and ground source heat pump led to reductions of 52% and 39%...

Canadian Hog Journal Summer 2019

Articles in the Summer 2019 Canadian Hog Journal Include: For the Love of Science: What is the Long-Term Production and Economic Impact of Feeding Deoxynivalenol-Contaminated Feed to Finisher Pigs? Mycotoxins continue to be a concern for agriculture. It may be possible to feed diets with higher levels of DON than currently recommended, but adjustments may be needed for reduced performance. Practical Environment Enrichment Strategies for Piglets Less pen-mate manipulation such as tail-biting,...

Canadian Hog Journal Spring 2019

Articles in the Spring 2019 Canadian Hog Journal Include: Hot Issues: Canada Food Guide Isn't Bringing Home the Bacon, African Swine Fever - Can it Be Stopped? Changes have been made to the Canada Food Guide with only three food groups now, with milk and meat combined into 'protein'. Plant-based protein is emphasized as well. Transmission of African Swine Fever  is through direct contact with infected pigs, ticks or stable...
