Abstract

The invention relates to a feed and specifically to a duck feed and a preparation method. The feed is prepared from the following raw materials by weight: 47.6 parts of corn flour, 19.7 parts of soybean flour, 10.0 parts of wheat bran, 5.4 parts of fish meal, 1.5 parts of calcium hydrogen phosphate, 6.0 parts of limestone powder, 0.3 part of iodized salt, 5.7 parts of beef tallow, 0.3 part of vitamin premix and 0.1 part of mineral premix. The preparation method comprises the following steps: preparing a fermented feed, that is, with corn flour, soybean flour and wheat bran as base materials, adding lactic acid bacteria and yeast and carrying out fermentation at a constant temperature of 30 to 32 DEG C for 25 to 30 days so as to prepare the fermented feed; adding fish meal, calcium hydrogen phosphate, limestone powder, iodized salt, beef tallow, vitamin premix and mineral premix into the fermented feed and carrying out uniform mixing so as to obtain a finished product of the duck feed. The beneficial effects of the invention are as follows: the raw materials are fermented, which enables ducks' absorption of nutritional components to be promoted and is favorable for ducks' absorption of nutrients and for growth of ducks.

Description

A kind of duck feed and preparation method

Technical field

The present invention relates to a kind of feed, specifically is a kind of duck feed and preparation method.

Background technology

At present general duck feed is premix+add energy feed+protein feed to process.Also with good grounds needs add some trace elements again, and the egg that duck is given birth to also increases the material composition of interpolation, thereby reach the purpose that improves the duck's egg nutritional labeling.But the weak point of above-mentioned feed is to be unfavorable for the effective absorption of duck to nutritional labeling.So far not the duck feed is not produced in fermentation.

Summary of the invention

The present invention provides a kind of duck feed and preparation method, is of value to promoting the absorption of duck to nutrition to promote the growth of duck.

Technical scheme of the present invention is following: a kind of duck feed has the raw material of subordinate's weight portion to process: 47.6 parts of corn flour, 19.7 parts of soy meals, 10.0 parts in wheat bran, 5.4 parts of fish meal, 1.5 parts of calcium monohydrogen phosphates, 6.0 parts of agstones, 0.3 part of iodized salt, 5.7 parts in butter, 0.3 part of vitamin premix, 0.1 part of mineral pre-mix.

A kind of preparation method of above-mentioned duck feed, concrete steps are following:

(1) preparation fermented feed: as base-material, add lactic acid bacteria, saccharomycete with corn flour, soy meal, wheat bran, processed fermented feed at 30-32 ℃ of following ferment at constant temperature 25-30 days;

(2) fermented feed is added fish meal, calcium monohydrogen phosphate, agstone, iodized salt, butter, vitamin premix and mineral pre-mix, mix thoroughly and be finished product.

The invention has the beneficial effects as follows:, help absorption and the growth of duck nutrition owing to, promote the absorption of duck to nutrition with fermenting raw materials.

The specific embodiment
