[International Livestock] The use of targeting enzymes in broiler diets can bring economic benefits without affecting the growth rate and meat production rate of broilers.
By better understanding the phytate and non-starch polysaccharide (NSP) composition of the feed, the use of targeted enzymes can reduce feed costs and phosphorus and nitrogen emissions from poultry farms.
Determine the composition of the diet substrate and its phytate and fiber content, and on this basis obtain the benefits of "overdosing" enzyme preparations - high dose or "overdosing" phytase to break down phytic acid ( Inositol hexaphosphate, IP6), maximizes the nutritional content of the diet through the combination of phytase and xylanase, and has been shown to maximize inositol hexaphosphate in the intestines of poultry Almost completely converted to inositol.
According to current standards, the addition of phytase/xylanase to the phytic acid and non-starch polysaccharide components in the diet can more stably reproduce the production performance under extreme nutrient levels. Moreover, research trials have shown that this method can reduce feed costs without affecting the growth rate and meat production rate of broilers.
In addition, the economic benefits of such a large nutrient component are directly proportional to the nutritional contribution of the current enzyme formulation application and the amount of phytate and fiber in the feed.
Phytate
The low phytate of phytate and phytate, a byproduct of phytase degradation, has a direct or indirect adverse effect on the utilization of minerals, proteins and amino acids and energy by poultry. However, by using an appropriate dose of phytase, phytate and its low ester compound, it can be rapidly degraded to inositol in the muscle and stomach of broilers.
Significantly improve feed utilization by increasing the utilization of mineral elements and amino acids, saving energy and providing inositol.
fiber
In addition to phytate, fiber is a major component of poultry feed. Xylanase promotes the degradation of soluble and insoluble fibers to form smaller and more fermentable fiber components. These smaller fiber components are capable of being fermented by the gut microbiota to produce volatile fatty acids and to allow the microbial population to evolve in a direction more suitable for fiber fermentation.
It has also been found that xylanase can increase the residence time of food in the intestine and promote the decomposition of the cell wall through the mechanical action of the stomach or stomach.
The overall effect of xylanase is improved nutrient digestibility, increased energy digestibility, and overall improvement in intestinal physiology.
Precise combination
By setting a 90% confidence interval and a significant margin of safety for the nutritional criteria, conducting animal experiments, and understanding the levels of phytate and fiber in the feed, the risk of an accurate combination strategy can be reduced.
Near-infrared spectroscopy is used to enable real-time analysis of phytic acid and fiber content in raw materials. Understanding and understanding the phytate and fiber content and variability of the raw materials in the final broiler feed will directly affect the amount of nutrients that can be saved in the feed.
The economic benefits of using a properly calibrated, appropriate complex phytase xylanase outweigh the benefits of simple “overdosing” phytase while reducing phosphorus and nitrogen excretion.
