Problems solved by technology

Oysters are the food with the most zinc content, followed by beef, lamb, animal liver, duck egg yolk, etc. The zinc content in plants is low, and the absorption and utilization rate in the human body is low. Therefore, people who often eat vegetables are prone to deficiency. zinc

Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific examples.

[0012] A high-zinc egg-duck feed contains the following components in air-dried weight percent: 30% corn, 26% wheat, 3% high-quality fish meal, 15% soybean meal, 5% DDGS, 5% rapeseed meal, and 5% cotton meal , soybean oil 0.5%, calcium carbonate 8%, calcium hydrogen phosphate 1.2%, additives 1%, zinc sulfate 0.1%, zinc methionine 0.2%.

[0013] The ratio of feed ingredients in this embodiment is reasonable, wherein crude protein is 18.84%, moisture is 11.12%, crude fat is 3.18%, crude ash is 12.63%, calcium is 3.61%, total phosphorus is 0.67%, and methionine is 0.42%. Metabolizable energy is 10.78 kJ / g.

[0014] Using the feed of this embodiment, 2,000 laying ducks were cultured in the Huizhou market. After 50 days, the egg production rate of the laying ducks was the same as before using the feed of the embodiment, and remained at a high level of about 91%, and the zinc conte...

Abstract

The invention relates to laying duck feed, in particular to laying duck compound feed, by which the laying duck can lay eggs with high zinc content. The high-zinc feed for laying duck is prepared from energy feed, an animal protein source, a plant protein source, a fat source, a calcium source, a phosphor source, an additive, zinc sulfate and zinc methionine. The invention adds the zinc sulfate and the zinc methionine in the feed and adopts the way of combined addition of inorganic zinc and organic zinc, so the increment of the feed cost is small, the influence on other metal element absorption is also prevented, and the regular egg laying property of the laying duck is guaranteed; in addition, the high absorption and utilization rate of the organic zinc has remarkable effect on the improvement of the zinc content of the duck egg.

Description

【Technical field】 [0001] The invention relates to a compound feed for laying ducks, in particular to a compound feed for laying ducks which can make duck eggs produced by laying ducks have higher zinc content. 【Background technique】 [0002] According to the national sample survey, the Chinese people's intake of zinc is obviously insufficient, which is only about 80% of the standard intake. Zinc is an essential trace element for the human body, and it is closely related to the growth and development of children. Zinc deficiency in children will cause symptoms such as loss of appetite, repeated infections, growth retardation, backward sexual development, and mental retardation. Adults need 13 to 15 mg of zinc per day. Lack of it can lead to loss of appetite, rough skin, growth retardation, and anemia. Long-term zinc deficiency can also cause sexual dysfunction and infertility. Oysters are the food with the most zinc content, followed by beef, lamb, animal liver, duck egg yo...
