What is a challenge of traditional body weight measurement methods in livestock?

Traditional body weight measurement methods in livestock often involve physically handling the animals, either by using a scale or a weighing platform that requires the animals to be moved into a specific area. This process can indeed be time-consuming, as it may involve rounding up and transporting livestock, which can take considerable time and effort from the handler’s perspective.

Moreover, the act of handling and moving livestock can be stressful for the animals themselves, leading to potential inaccuracies in weight measurements due to stress-induced physiological changes. Stress in livestock can cause fluctuations in weight and health indicators, thus affecting the reliability of the readings obtained. Therefore, traditional methods not only disrupt the routine of the animals but may also compromise their welfare, making this a significant challenge in livestock management.

The other choices reflect issues related to advanced technology, inefficiency regarding relocation, and the reliability of data, but the aspects of time consumption and animal stress are particularly relevant to traditional practices and highlight a major drawback in terms of both efficiency and animal welfare.
