How we manage birds has a huge impact on their productivity, health, behaviour, and profitability. Lighting programs are an important management tool for poultry production. Traditionally, broiler chickens have been raised with little (1 hour) or no dark, with the belief this allowed them full visual access to their environment now know that birds need a period of darkness for optimal welfare and production. When birds are given a continuous period of 4-6 hours of darkness in a 24 hour period, they are more productive, healthier, more active, and sleep better.

The objective of this research was to understand the effects of different durations of darkness on broiler performance, feeding behaviour, and feed rates.

Stocking density has the ability to directly influence economic return for producers however, it is important to consider other factors that may be affected by stocking density. While the majority of stocking density studies were conducted in the 1990’s or earlier, past studies have well documented the effects of stocking density on performance. There are few studies that evaluate how stocking density impacts the health, behaviour and overall well-being of the bird.

Another issue with stocking density research is that there are many other factors linked to stocking density that contribute to negative bird performance and welfare, such as feeder and drinker space, poor air quality, and poor litter quality. This study attempted to account for these factors by equalizing feeder and drinker space on a per bird basis, monitoring air quality for CO₂ and ammonia and adjusting ventilation based on stocking density, and by evaluating litter moisture.

The aim of this research was to study the effects of stocking density with a comprehensive approach, ensuring that confounding factors were accounted for.

Thirty-two livestock industry professionals and stakeholders took part in a daylong conversation around strategies to mitigate pain for livestock. The emphasis was on sharing and confirming current issues, identifying knowledge gaps and exploring ways to reach the desired goal of mitigating pain. Contributors represented livestock researchers, veterinarians, animal welfare specialists, academia, government, industry organizations and pharmaceutical companies. Participants shared updates on the present state of pain control in the livestock industry in Alberta.

I fell in love with honey bees after having the opportunity to do a couple hive inspections with a professor while I was studying abroad. When I returned to Canada to finish the second half of my masters degree on an invasive fish species in Alberta, I decided to take a beginner beekeeping course. Needless to say, my fascination with these creatures only grew stronger. A year after I graduated, I was lucky to land a job working as an apiculture research technician at Alberta Agriculture and Forestry. As of right now, I am hoping to expand my knowledge of honey bees and colony management, as well as develop specific technical skills to help the industry diagnose and manage pests and diseases. 

The beekeeping industry in Alberta is the largest in Canada, and is home to over 315,000 honey bee colonies. Both honey production and the provision of pollination services to crops in Alberta and British Columbia are key aspects of the industry. Our goal at Alberta Agriculture and Forestry is to support Alberta’s beekeepers to ensure the industry is strong and resilient, and honey bees are healthy for the future. One of our primary objectives is to assist beekeepers in developing and applying Integrated Pest Management (IPM) systems in their operations to reduce the risks and costs associated with colony loss from disease outbreak.

The livestock industry is making great strides in decreasing antimicrobial usage which indirectly helps with antimicrobial resistance. From veterinarians setting the example, to cow-calf and feedlot operations implementing effective coping strategies, huge progress is being made. There are management changes which can be made to minimize disease incidence. The policymakers can also look at ways to increase research in antimicrobials or alternative treatment methods. Monitoring and surveillance of drug resistance such as an antimicrobial task force headed by the veterinary colleges, look at the evolution of antibiotic resistance. What can you do today as a cattle producer in whichever segment of the cattle industry you are involved? This article will address changes you can make that may decrease disease incidence and therefore the need for antimicrobial use in your calves.
