Changing global animal husbandry and social problems are driving the future direction of poultry nutrition. In the future, we may have to change the feed formulation to meet the needs of science and society and strengthen the role of feed enzymes in poultry nutrition.
1. Feed antibiotics: the main concerns of consumers
The EU ban and the voluntary discontinuation of feeding antibiotics in other parts of the world to varying degrees will put additional pressure on animal intestinal and systemic health.
There is growing concern about antibiotic substitutes that can maintain good flora and intestinal health. These substitutes include enzymes, probiotics, essential oils, plant drugs and organic acids. These alternatives have been extensively tested over the past 10 years and will continue to be evaluated in the future.
In addition to antibiotic substitutes, comprehensive nutritional and management measures are needed to promote intestinal health and maintain good intestinal flora. These measures include:
1) Use more digestible diets.
2) Reduce dietary protein level and improving amino acid balance.
3) Whole grain feeding can promote the development of muscles and stomach.
2. Importance of intestinal integrity
Intestinal integrity is often neglected in intestinal health, but it is important to realize the genetic potential of poultry. Maintaining intestinal integrity of commercial poultry can maintain intestinal health, fully express the growth and production genetic potential of poultry, and make full use of the nutritional components of feed enzymes.
3. Environment and Sustainability
In the past, the main objective of formula feeding was to provide nutrients (nutrient intake). If there were doubts about the utilization of key nutrients or the nutrient requirement was uncertain, diets were often over-matched. This practice is no longer recognized, because it not only causes waste, but also excess nutrients are discharged in feces and eventually become a source of pollution.
From the nutritional point of view, the best measure is to provide fowl with feed enzymes that match the requirements, and improve the utilization efficiency of nutrients, thereby reducing fecal discharge. Feed enzymes are the most promising products to improve the utilization efficiency of nutrients.
5. Feed Additives and Sustainability
Feed enzymes play an important role in maximizing the release of nutrients. It can be predicted that the development of feed enzymes will play a role in various dietary formulations.
