Problems solved by technology

At the same time, improper nutrient levels of laying hen feed are likely to cause poor bone development of laying hens, especially poor development of long bones, and the amount of calcium reserves will be small. When eggshells are formed at night, calcium deficiency will result, resulting in poor eggshell quality. Difference

preparation example Construction

[0049] In order to better understand the laying hen feed of the present invention, the application also provides a preparation method of the laying hen feed. The above-mentioned preparation method of laying hen feed comprises the following steps: rice husk powder, 25-hydroxyvitamin D3, mineral elements and calcium hydrogen phosphate according to (20-35): (0.5-2): (3-6) : (15~30) mass ratio is carried out pre-mixing operation, obtains pre-mixture; Composite enzyme preparation, feed additive, salt and solvent are according to (2~5):(25~40):(6~15):(30 ~60) in the mass proportion of the pre-mixture is sequentially added into the pre-mixture and stirred to obtain a stirred mixture; the stirred mixture is granulated to obtain a granular feed; the granular feed is sieved and classified to obtain the obtained The feed for laying hens during laying period.

[0050] The above-mentioned laying hen feed has a simple preparation method, is easy to operate, and has high preparation efficie...

Embodiment 1

[0064] The rice husk powder, 25-hydroxyvitamin D3, multivitamins, mineral elements and calcium hydrogen phosphate are premixed according to the mass ratio of 20:0.5:3:15 to obtain the premixture. Then the compound enzyme preparation, feed additive, salt and solvent are sequentially added to the pre-mixture according to the mass ratio of 2:25:6:30, and the stirring operation is carried out, wherein the stirring speed is 200 rpm, and the stirring time is 2 minutes. After the stirring operation was completed, the stirred mixture was put into a granulator for granulation operation, wherein the granulation temperature was 75°C. After the granular feed is obtained through the pelletizing operation, the granular feed is sieved and classified to obtain the laying hen feed.

Embodiment 2

[0066] The rice husk powder, 25-hydroxyvitamin D3, multivitamins, mineral elements and calcium hydrogen phosphate are premixed according to the mass ratio of 35:2:6:30 to obtain the premixture. Then add the compound enzyme preparation, feed additive, salt and solvent into the premix in sequence according to the mass ratio of 5:40:15:60, and carry out stirring operation, wherein the stirring speed is 300 rpm, and the stirring time is 5 minutes. After the stirring operation was completed, the stirred mixture was put into a granulator for granulation operation, wherein the granulation temperature was 105°C. After the granular feed is obtained through the pelletizing operation, the granular feed is sieved and classified to obtain the laying hen feed.

Abstract

The invention provides a feed for laying hens in an egg producing period and a preparation method of the feed. The feed for the laying hens in the egg producing period comprises 0.5-2 parts of 25-hydroxyvitamin D3, 1-3 parts of complex vitamins, 3-6 parts of mineral elements, 2-5 parts of a complex enzyme preparation, 25-40 parts of a feed additive, 20-35 parts of rice hull powder, 15-30 parts of dicalcium phosphate and 6-15 parts of table salt. According to the feed for the laying hens in the egg producing period disclosed by the invention, the problem that the laying hens are separated from anuses in the raising process can be solved, the intensity of eggshells can be improved, and the egg breaking rate can be greatly reduced.

Description

technical field [0001] The invention relates to the field of chicken feed preparation, in particular to a laying hen feed and a preparation method thereof. Background technique [0002] Laying hens refer to chickens that are raised to lay eggs to supply eggs. Unlike broiler chickens, the main issue of people raising laying hens is to improve egg quality and maintain or increase egg production, not to improve chicken quality. Eggs are the main source of income for laying hens. [0003] However, at present, laying hens are prone to prolapse of the anus during the breeding process. Prolapse of the anus means that the cloaca or oviduct cannot retract normally after the laying hen lays eggs, and a part of it stays outside the anus. It is more common in the primiparous period or the rich period after the opening of production, and it is more common in high-yielding chickens. The incidence rate is 1%-2%, and some chickens are as high as 3%-5%. If the prevention is not timely, it ...
