Characterization of proteoglycan products of naturation of chitosan extraction liquid waste with sulfate ions

The process of naturation of chitosan extraction liquid waste into proteoglycans with various types of binders is an effort to make new materials / materials that are expected to provide benefits to increase livestock productivity. The new material (proteoglycan) is formed through a reaction mechanism that is highly dependent on the original component as well as additional components that function as receptors (inhibitors) or activators (triggers) for the formation / occurrence of molecular adhesion (chelating) to a core chain. In addition, the process of naturation of liquid waste is also an effort to manage or handle the environment from waste which if not handled can have a negative impact on the environment. This can happen because the denaturation of protein components or molecules contained in liquid waste becomes pollution due to the decay process.

The purpose of the study was to obtain the character of proteoglycan quality as a result of the addition of various types of sulphate ion binders through measuring the digestibility and hematologic values of blood in broiler chickens. The study used experimental methods in the laboratory. The experimental design used was a Complete Randomized Design (6 X 4), with six treatments (3 types of chemical product binders and 3 types of biological product binders), which were repeated four times. The effect of the treatment was statistically tested by fingerprint analysis, and the difference between treatments was tested with the Duncan Multiple Distance Test.

The research was carried out in two stages, namely the preparation stage (making proteoglycans with the addition of three types of sulphate ion binders), and the product quality testing stage. Product testing through measurement of digestibility (dry matter and protein) and hematologic (number of erythrocytes, leukocytes, and haematocrits) values of broiler blood.

The results showed that liquid waste extracting chitosan from shrimp shells (both through chemical and biological processes) can be used as a source of making proteoglycans and can be used as a feed supplement in broiler chicken rations. Quality characteristics of proteoglycan products: good quality Proteoglycans of chemical and biological processes with potassium sulphate binders; Moderate quality chemical and biological process proteoglycans with ammonium sulphate binders, and biological process proteoglycans with sodium hydro sulphate binders; and Poor-quality Proteoglycan chemical process with sodium hydro sulphate binder. The number of erythrocytes, leukocytes and haematocrits blood of broiler chickens are normal for all types of products.
