Abstract

The invention discloses a preparation method of a feed additive for laying hens. Palm meal and a mixture of cassava residues and potato residues which are mixed in a discretionary ratio are used as fermentation substrates, and fermentation is performed through mixed bacterium fluid, so that the feed additive is prepared, wherein the mixed bacterium fluid consists of aspergillus niger, viridin andcandida utilis or consists of aspergillus niger, viridin and beer yeast. The invention further provides the feed additive for the laying hens, and a laying hen feed comprising the feed additive for the laying hens. The feed additive for laying hens is completely free from antibiotics and animal-derived protein, so that when the feed additive is added to the laying hen feed, nutritional requirements of the laying hens can be met, and the laying hen feed is easy to absorb and high in utilization rate and has the effect of enhancing the immunity.

Description

technical field [0001] The invention belongs to the technical field of laying hen breeding, and relates to a laying hen feed additive used to replace protein feeds such as antibiotics and animal source bone meal and fish meal, a preparation method thereof, and a laying hen feed containing the additive. Background technique [0002] In recent years, with the development of science and technology and economy, and the improvement of people's living standards, consumers' consumption of animal-derived foods has increased sharply, and higher and higher requirements have been put forward for the quality of animal-derived foods. Chicken and eggs are the main animal source foods for humans. Since the 1980s, the rise of my country's large-scale and industrialized chicken industry has greatly eased the contradiction between urban and rural residents' demand for eggs and chicken. However, diseases have become a bottleneck restricting its development. Although the emergence of antibioti...
