Symposium: 'Nutrient requirements and animal health'

A large variation in the production performance of pigs and poultry between farms is observed in practice. This is related to variation in environmental and management factors and to variation in health status of animals.

In a low or sub-optimal health status the immune system of the animal is activated. An activated immune system has specific nutrient requirements and increases the competition between nutrients available for maintenance purposes, functioning of the immune system and for body protein deposition in growing animals. The former indicates that nutrient requirements can be affected by health status and indicates that diets should be optimized taking into account health status of the animals on farm. The latter will not only result in an improved nutritional support of the animal under a variety of health conditions but also contributes to an overall improvement of nutrient utilization and resource efficiency as well as to a reduction of nutrient excretion into the environment.

At the symposium international acknowledged experts from abroad and scientists from Wageningen UR will present their views on this topic.
