Why animal raisers prefared to sell whole rather than to slaughtered?
5 answers
Animal raisers prefer to sell whole animals rather than slaughtered ones due to various reasons. Selling whole animals can reduce stress and aggressive behavior, as seen in intact groups of entire male pigs compared to mixed control pigs. Additionally, the handling and transportation processes involved in sending animals to the abattoir can induce stress, affecting liveweight, carcass traits, and muscle properties. The pre-slaughter period is particularly stressful for animals due to changes in environment, social disturbances, handling, and physical stress factors like food deprivation and climatic conditions. Implementing pre-slaughter practices based on animal behavior and proper staff training can help reduce stress, prevent unnecessary suffering, and improve overall meat quality. Therefore, selling whole animals can contribute to better animal welfare and potentially enhance meat quality.
