Problems solved by technology

[0003] In the prior art, due to the different sizes of shell meal and bone meal, which affect the pecking effect, other fine powder calcium feeds are not suitable for supplementary feeding, which in turn leads to the effect of free-range laying hens on calcium intake when eating feed. Not good, it affects the egg production rate of free-range laying hens; moreover, the current feed nutrition is not balanced enough

Abstract

The invention discloses feed suitable for free-range laying hens in the technical field of feed production. The feed comprises the following raw materials in percentage by weight: 62-67% of corn, 18-24% of soybean meal, 0-6% of bran, 4-8% of stone powder and 3-7% of a premix, wherein the sum of the weight percentages of the raw materials is 100%. An eggshell powder is added in the feed. The pecking effect is affected due to different sizes of shell powder, bone meal and the like, and other fine powdery calcium feed are not suitable for supplementary feeding, so that the calcium feeding effectof the free-range laying hens is poor when the free-range laying hens eat the feed, and the problem can be effectively solved by additionally adding 4% of the eggshell powder in the premix. The addedeggshell powder is sufficient in the content of inorganic salts, the content of calcium carbonate is about 95%, the total content of magnesium carbonate and calcium phosphate is about 4%, and the balance is a small amount of organic substances, so that the calcium content in the feed is supplemented, the feed is easily absorbed by the free-range laying hens, the growth and development of the free-range laying hens are promoted, and the egg yield is improved.

Description

technical field [0001] The invention relates to the technical field of feed production, in particular to a feed suitable for free-range laying hens. Background technique [0002] Feed is the general term for the food of animals raised by all people. In a narrower sense, general feed mainly refers to the food of animals raised in agriculture or animal husbandry. The feed includes soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives and more than ten varieties of feed materials. my country's feed industry is an emerging industry. In 2016, the total output of commercial feed in the country reached 209.18 million tons, with a total output value of 801.4 billion yuan. According to the level of meeting the nutritional needs of animals, feed products can be divided into: (1) full-price compound feed. Contains feed that meets the needs of animals for protein, energy, macro minerals, trace minerals, vit...
