A PREPARATION METHOD OF PELLET BINDER USING SPENT LIQUOR OBTAINED FROM ALKALINE SULFITE ANTHRAQUINONE COOKING OF PINE BARK WASTE

摘要

The present invention relates to a method for preparing a pellet feed for chicken feed from waste liquor obtained from alkaline sulfite-anthraquinone-digesting pine bark and at a high possible dilignin possible cooking condition. Alkaline sulfite-anthraquinone effluent from pine bark can be neutralized with acid and added to the feed binder as 0.25-2.0% per feed weight to maintain good pellet durability. The pellets thus prepared are fed to broilers to obtain good weight gain and feed rate. When these pellets are fed to laying hens, they can be used for laying hens because they maintain egg laying rates of more than 95% and increase egg weight as well as egg yolk coefficient, egg coloration and haugh unit, which affect egg quality. .
