Behaviour of Pigs in Large Group Auto-Sort
A concern for having larger groups of pigs together is a possible rise in aggressive behaviours, however previous research shows the aggression levels are similar in small and large groups. Eating behaviour may change, especially as new technology such as large group auto-sort (LGAS) systems...
Free Space Utilization of Sows in Free Access Stalls
Group housing systems can produce more active and social sows, leading to a healthier pigs. It will increase muscle strength and decrease lameness with stronger bones from the ability to move around. An example of a group housing system is free access stalls. The degree...
The Plant Extract Micro-Aid‚ has Unexpected Effects on Litter Size
Micro-Aid® helps reduce ammonia emission and odours from livestock production facilities and is a natural plant extract. When sows are fed Micro-Aid®, their colostrum has increased levels of immunoglobulins. This may help piglets gain weight. The impact on their piglets is that litter size increased...
Assessing Enrichment for Sows
Most research on the different forms of enrichment are done on piglets and growing pigs. In these pigs, some benefits include reduced aggression and fear, fewer behavioural vices and improved growth. Older animals such as sows differ and generally prefer manipulable and destructible enrichments compared...
Early Detection and Interventions for Reducing Lameness in Gestating Sows
The second most common cause of culling is sow lameness, after reproductive failure. Hoof problems are related to good conformation and genetics, but also fully slatted concrete systems. Horn growth increases due to higher pressure exerted from the concrete floor. Claw overgrowth and heel erosion...
Using ‘Translactational Analgesia’ to Reduce Piglet Pain at Castration
Increasing concern from the public is found regarding painful livestock procedures such as castration. Pain medication is not commonly used in piglet castration. Affordable and practical methods for pain medication delivery are needed to increase the acceptance by producers. In cattle, analgesics can be transferred...
Loading Facilities for Market Hogs: Saskatchewan’s Top 10
Loading facilities can result in longer loading times, increased incidence of rough handling and prod use if poorly designed. Stress associated with this can affect meat quality, carcass and also increase the amount of downer pigs and losses. Ten Saskatchewan barns were observed to see...
Validation of Sampling Techniques for Assessing Stress in Pigs by Salivary Cortisol
Cortisol is often used as a measure of stress in pigs. Multiple samples are often taken to see how long it is elevated and when the peak of the stress response was. Adrenal function tests are used when studying long term stressors to see if...
Stress Response and Meat Quality of Pigs Transported in a Pot-Belly Truck During Summer and Winter
Transport of pigs involves a large number of potential stressors that could have an effect on meat quality and value of the carcass. Long distances and extreme weather conditions are often present in western Canada transportation. Dual purpose trailers can accommodate pigs or cattle, with...
Handling Stress During Marketing of Pigs from Large Groups
Pigs from conventional small groups are less socially tolerant compared to pigs from larger groups and fight more when in re-grouping scenarios such as marketing. Pigs from large groups are easier to load and handle as well. Fewer deaths have been recorded during marketing when...
