The invention discloses a method for producing a laying hen
feed additive by efficiently utilizing orange peel and shaddock peel. The method comprises the steps that firstly, raw materials which comprise, by weight, 15-17 parts of orange peel
powder, 20-22 parts of soybean dreg
powder, 24-26 parts of shaddock peel
powder, 4-6 parts of camellia seed powder, 5.6 parts of
isochrysis galbana powder and 9 parts of auxiliaries are prepared, wherein the auxiliaries comprise
montmorillonite, L-
leucine and
chitosan according to the ratio of 1.7:1.1:1.6; secondly, all
raw material coarse powder is mixed and then evenly mixed with the auxiliaries; thirdly, the mixture is processed with a high-energy vibrating mill for 15-30 min, the high-energy vibrating mill is halted for 2.5 min, then the mixture is processed for 12-13 min, two times of different
solid-state mechanical chemical reactions take place in all the raw materials, screening is performed with a 400-mesh screen, and the finished product is obtained. According to the method,
carotenoid components in the shaddock peel and the orange peel can be efficiently released, and the
bitter taste is significantly reduced; by using the laying hen
feed additive, the color of egg
yolk is obviously increased, economic benefit can be brought to enterprises, and the
environmental protection pressure can be relieved.
