The Nutrition Characteristics and Application Test on Layer Feed of FH Biological Activity Feed Yeast

The nutrition characteristics of FH biological activity feed yeast are as follow:High quantity of digestive protein,necessity of amino-acid equilibrium ;Contain relatively rich B Species Vitamin and a great number of digestive ferments;it also shows good biological activities as a result of the application of low drying temperature;Contain microelements which can enhance the ferment within the animal body.In breeding experiments, FH biological activity feed yeast and several protein sources which are in spreading at present are combined into five groups of feeds,layers are divided into five groups for the comparative experiment. The result shows that;the group with FH has a higher ratio of egg producing, quantity of egg-producing,feed remuneration and economic benefit than the contrasting group. It is a comparatively ideal protein source and biological additive.
