Feed for laying ducks

Abstract

The invention relates to the technical field of animal feeding, in particular to feed for laying ducks. The feed for the laying ducks is prepared from, by mass, 30-50 parts of corn, 20-40 parts of wheat, 15-25 parts of rapeseed meal, 10-16 parts of mountain flour, 3-5 parts of calcium hydrogen phosphate, 4-8 parts of calcium carbonate, 3-6 parts of salt, 2-6 parts of a vitamin additive, 2-5 partsof an enzyme preparation, and 2-4 parts of a microbial preparation. According to the technical scheme, the feed has the advantages that the formula of the feed is reasonable, the cost is low, the laying rate of the laying ducks fed by the feed reaches 94%, the nutritional value of the laying ducks for production is high, the taste is delicious, and the feed is favored by people.

Description

technical field [0001] The invention relates to the technical field of animal feeding, in particular to a feed for laying ducks. Background technique [0002] Laying duck has excellent characteristics such as high yield and strong disease resistance, and is a kind of poultry with a large number and wide distribution. Nearly 300 million laying ducks are raised in my country, accounting for 80% of the world's total. The variety resources are particularly rich, mainly small and medium-sized individuals. Fresh duck eggs are rich in nutrition, comparable to chicken eggs. Duck eggs have protein, phospholipids, vitamin A, vitamin B 2 , Vitamin B 1 , vitamin D, calcium, potassium, iron, phosphorus and other nutrients. It tastes like eggs, which are oily and have a good taste, and are favored by people. The deep-processing products of duck eggs are also favored in the international market. At present, the global egg duck industry is showing vigorous vitality. [0003] However, ...

Problems solved by technology

[0003] However, the production of laying ducks is uneven, especially in the low quality of input products, and the environment is too extensive, which cannot meet the requirements of intensive production and hinders the development of laying duck production.

For a long time, due to the unreasonable feed structure in the production of laying ducks, the laying ducks have low egg production rate, light egg weight, and low feed output rate in the later stage, making it difficult to exert their genetic potential. Not only the laying cycle is shortened, but the scale production benefits cannot be reflected , and the quality of duck eggs is poor, which has seriously affected the development of the entire laying and duck industry.

[0004] The existing feed for laying ducks has unreasonable composition ratio and high cost, which increases the production cost of laying ducks and limits the development of light and elegant
