La agilidad es la capacidad para anticiparse a los cambios, responder, adaptarse rápidamente y prosperar en un entorno difícil. La agilidad intestinal es un nuevo término acuñado para describir la capacidad del ave para adaptarse a los factores de estrés nutricional con una respuesta más eficiente energéticamente y de forma más rápida de lo que lo haría normalmente.
There is scientific evidence suggesting that for genetic selection, improving the ability of pigs to cope with stressors may be a better way of improving pig performance than selecting only for increased growth potential.
In recent years a better understanding of the phytate molecule has lead to the realization that novel phytases have benefits beyond phosphorus release. Phytases have been shown to reduce the anti-nutrient effects of phytate in animal diets by degrading it, thereby, increasing the availability of energy and amino acids and providing the potential for phytases to further reduce the cost of feed.
Energy is an expensive ingredient in today's pig diets. The downside of cheaper feed energy sources is often a reduced availability of nutrients, resulting in a trade-off between cost of diet and animal performance. Carbohydrase enzymes are recognized for their ability to increase the flexibility to use less digestible energy sources in feed formulations without compromising animal performance in several markets.
The days are gone where formulating pig diets was a simple calculation exercise in least cost diet formulation. The future requires creativity in feed formulation as well as a much deeper understanding of how nutrients are processed and how they interact within the animal in order to stay ahead of the game in profitable pig production.
