​As we face the increasing size of the human population, it is projected that meat consumption will increase as well. At the same time, consumers are more aware and have increased their interest in traits related to animal welfare and health. By far, most pigs are finishers, kept in groups from 10 to, possibly, 400 or more. In these groups social skills of animals help to reduce stress. Too often we only observe from the negative side: traits like tail biting, aggressive behaviours resulting from stress, aggressive social interactions with other pigs and with humans.Behavioural traits have the potential to change the efficiency of pork production in the future, while at the same time improving welfare and reducing medication. Therefore, they are becoming economically important traits in breeding programs.

The decision to euthanise on farm is a difficult decision every producer has to make. Euthanising on farm may be necessary when a sick or injured animal is unresponsive to treatment, has a poor chance of recovery, and is unfit for transportation. When not performed correctly, on-farm euthanasia can cause unwanted pain and suffering.

Gunshot is one of the most common methods of euthanasia producers perform for production species.Benefits of this method are that it is suitable for all ages (given that the appropriate firearm is used), if properly performed it results in immediate unconsciousness, cost is relatively low, and it does not require the producer to get too close to the animal. This is likely not the most appropriate method for poultry, however. Regardless of the method used, producers must take safety measures for themselves and bystanders. Refer to your species-specific “Code of Practice” for more information on proper placement and appropriate methods of euthanasia (www.nfacc.ca).

​Producers typically castrate their bull calves anywhere between 1 week and 5 months of age and less commonly between 6 to 9 months of age with the exception of bulls destined for breeding. The most common methods used are band castration that restricts blood flow to the testicles and knife castration that involves immediate removal of the testicles by cutting. (more…)
