Chemical composition and inherent properties of offal from calves maintained under two production systems.

The aim was to evaluate the influence of organ and calf type on the chemical composition, mineral concentration, fatty acid profile and inherent properties in offal. Organ type influenced (p<0.01) all evaluated characteristics, whereas calf type to a lesser extent affected mineral content. The highest contents of K, Zn and Fe were found in liver. The heart of veal calves contained the highest contents of Mg and Mn. In addition, the most favorable fatty acid profile was also found in hearts, by reason of the lowest SFA and highest PUFA percentage and h/H ratio. Significantly higher values of PUFA percentage, PUFA/SFA ratio, and content of CLA were found in organs of suckler beef, which is associated with the beneficial effects of grazing on the fatty acid profile. Results could help to increase the consumption of calves' offal and its utilization in meat processing.
