General Community / Extrusion processing of feed making
« เมื่อ: 16/01/23, 10:42:13 »There has been better performance in swine, fish and poultry fed on extruded pellets than those fed on the mash. The better performance can be attributed to:
The heat used in feed conditioning breaks down starch into its constituent monomers that are further broken down to monosaccharaides. On the other hand proteins are broken down into smaller polypeptides. Is cattle feed business profitable? This enhances feed digestibility due to the large surface area exposed to the enzyme hydrolysis, hence better performance of animals fed these feeds.
During pelleting, the nutrients tend to concentrate in the product and pellets are also bound together. This minimises wastage during feeding and transportation hence increasing average daily gain.
It improves energy digestibility in cereal based diets due to starch gelatinisation, unlike in the mash leading to better performance of early weaned pigs fed extruded feeds.
Helps in improved faecal digestibility of some amino acids in chicken.
Increases digestibility of proteins, amino acids and nitrogen by denaturing of the former and modifying side chains of amino acids. Starch gelatinisation together with the above changes on proteins results in better digestibility, increase feed intake, improved feed conversion ratio and performance in chicken.
Extrusion results in starch gelatinization which makes it more susceptible to amylase, this enhances starch digestibility. This improves poultry performance.
