Technical Field
The invention relates to the technical field of feed production, in particular to a feed suitable for free-range laying hens.
Background
The term "feed" is a general term for food of all human-raised animals, and in a narrow sense, a general feed mainly refers to food of agricultural or animal-raised animals. The feed comprises more than ten kinds of feed raw materials such as soybean, soybean meal, corn, fish meal, amino acid, miscellaneous meal, whey powder, grease, meat and bone meal, grains, feed additives and the like. The feed industry in China is a new industry, the total yield of commercial feed in 2016 years in China reaches 20918 ten thousand t, and the total yield is 8014 hundred million yuan. Classified according to the level of meeting the nutritional needs of animals, feed products can be divided into: (1) complete compound feed. Contains feed meeting the requirements of animals on protein, energy, macrominerals, trace minerals, vitamins and various nutritional and non-nutritional additives. Can be directly fed to animals. (2) And (4) concentrating the feed. Usually, the energy feed in the feed formula, such as corn, wheat, bran, etc., accounts for more than 50% of the formula, and the raw materials are most purchased by breeding manufacturers or other manufacturers, in order to reduce the transportation cost, the feed manufacturers design feed products without energy raw materials, and the breeding manufacturers can produce complete compound feed with relatively low cost after purchasing the products and mixing the products with the self-produced or self-purchased energy raw materials. (3) And (4) premixing feed. In order to further meet the requirements of scale feeders on refined feeding and cost reduction, feed producers design premixed feed products, which mainly contain minerals, vitamins and various nutritional and non-nutritional additives.
In the prior art, since shell powder, bone meal and the like are different in size, the pecking effect is influenced, other fine powdery calcium feeds are not suitable for supplementary feeding, the calcium feeding effect is not good when the free-range laying hens feed the feeds, and the laying rate of the free-range laying hens is influenced; moreover, the nutrition of the current feed is not balanced enough.
Therefore, a feed suitable for free-range laying hens is provided to solve the problems.

The feed for the free-range laying hens prepared in the embodiment is used in the late peak period of the free-range laying hens.
Comparative example
The raw materials and the preparation method are the same as those of the two examples, but the feed with the grain diameter of 3-4mm prepared in the comparative example is used for free-range laying hens in the estimated laying period, the peak period and the later peak period.
Result detection
1. In the experimental method, 2000 laying hens are separately raised in the first henhouse and the second henhouse, the feed prepared in the first embodiment, the second embodiment and the third embodiment is respectively used for feeding the free-range laying hens in the first henhouse in the pre-delivery period, the peak period and the later period of the peak period, and the free-range laying hens in the second henhouse are respectively fed by adopting the method in the comparative example in the pre-delivery period, the peak period and the later period of the peak period, and the average egg laying rate in months is calculated. Specific data are shown in table 1 below.
Table 1 egg production rates
From the above table it follows: the feed prepared by the three proportions is correspondingly fed in three stages, and the average egg laying rate per month is higher.
