Compound feed additive for laying ducks, capable of increasing color of yolk, and use method

Abstract

The invention discloses a green safe laying duck feed additive and a use method. The additive consists of 15-25 parts of alfalfa, 20-30 parts of shrimp shells, 10-20 parts of three-coloured amaranth,10-15 parts of rhizoma coptidis, 10-15 parts of radix curcumae, 5-10 parts of European verbena herbs, 15-25 parts of dried ginger, 15-20 parts of fructus forsythiae, 15-25 parts of radix codonopsis and 5-10 parts of hericium erinaceus. The use method comprises the following steps of adding 20kg of the feed additive disclosed by the invention to 1000kg of a feed to obtain a mixture, and during feeding in the morning, firstly feeding the laying ducks with 30% of a feed fed once on the same day to guarantee that the laying ducks can quickly collect the feed mixed with the additive disclosed by the invention under the hungry foraging state and to guarantee that effective components can enter bodies of the laying ducks at the highest speed. Through adoption of the feed additive disclosed by theinvention, the color of duck egg yolk can be notably increased, production increase of duck eggs is promoted, the immunity of the laying ducks is enhanced, and the raising benefits are increased.

Description

technical field [0001] The invention belongs to the technical field of poultry feed additives, and in particular relates to a compound feed additive for laying ducks and a use method thereof. Background technique [0002] my country is the largest country in the breeding and consumption of laying ducks. In recent years, the overall development of my country's egg duck industry has been stable and has broad prospects. According to statistics, from 2012 to 2014, the average annual breeding volume exceeded 250 million, the annual egg production was more than 5 million tons, and the total output value of the laying duck industry exceeded 33 billion. Duck eggs are rich in nutrients, rich in protein, phospholipids, etc., especially minerals and trace elements are higher than eggs. Duck eggs are suitable for most people, especially for patients with physical weakness after illness, hot and dry cough, dry throat and sore throat, high blood pressure, diarrhea and dysentery. The de...
