Optimal timing for the slaughter of American bison to obtain high-quality meat

The timing of American bison slaughter directly impacts product characteristics such as tenderness, flavor, and total meat yield. Specialists note that the physiology of these animals differs from that of cattle, which requires a specific approach to determining readiness for slaughter. An optimal age of 2.5–3 years allows for sufficient muscle mass development with a minimal amount of connective tissue.

When assessing an animal's readiness for slaughter, farmers should pay attention to several key indicators: a live weight of 1,000 to 1,200 pounds, a Body Condition Score of 5–6, as well as the presence of well-developed musculature and an adequate layer of fat cover on the carcass. It is also important to consider the sex of the animal: males mature faster and may be ready for slaughter at 2.5 years, whereas females may require more time to grow.

Failure to meet slaughter deadlines leads to economic losses. Slaughtering too early reduces carcass weight and impairs taste qualities due to insufficient muscle and fat development. Delaying slaughter increases feed costs without providing significant gains in quality or product volume. A critical factor influencing development is the diet: a balanced feeding regimen is essential for proper growth and the formation of high-quality meat.

To preserve product characteristics, humane handling and the minimization of pre-slaughter stress are of great importance. Stressful conditions can lead to the "dark cutting" defect (dark, firm, and dry meat), which significantly reduces the value of the carcass. The post-slaughter processing procedure should include rapid cooling to an internal temperature of 40°F within 24 hours followed by meat aging. Utilizing dry or wet aging technologies helps break down connective tissue and improve product flavor profiles. The dry method allows for a more concentrated taste, while the wet method contributes to better moisture retention.
