Nutritionists should first develop confidence in the quality of the alternative ingredients and reduce the risk by formulating low inclusion levels.
The poultry industry continues to face many challenges to obtain maximum profits. It’s an industry that relies on maximum efficiency and small margins. Feed accounts to nearly 70% of the total production cost (Photo 1).
Therefore, the impact that feed cost has on input costs and profitability is constantly being scrutinized and considered by many as a “pressure point” in decision making.
It is the responsibility of the nutritionist to constantly evaluate alternatives that may reduce feed costs without affecting maximum profitability.
From a nutritional standpoint:
Feed enzymes largely focus on improved feed cost-savings (through improved feed utilization), rather than increases in live performance. They represent one of the greatest tools available to nutritionists to improve feed utilization.
Improving nutrient digestibility of phytate bound phosphorus
Removal of non-starch polysaccharides (NSP) that interfere with energy utilization and protein digestion, respectively
Today, phytases are commonly used in the industry and recently, carbohydrases and proteases have become very attractive to nutritionists. Current increases in corn and soybean meal costs have presented an opportunity for nutritionist to use carbohydrases and proteases.
Cereals, such as corn and wheat, contain a high amount of arabinoxylans, with wheat arabinoxylans almost doubling the amount of
