Description
Technical Field
The invention relates to the technical field of poultry feed, in particular to premix for laying hens in the initial stage of laying, a preparation method thereof, complete feed thereof and application thereof.
Background
Laying hen breeding is an important component of livestock husbandry in China, in 2019, 14 hundred million laying hens are bred in China, and the number of laying hens fed is the first in the world. The monthly stock of commercial laying hens is increased in China compared with 2018, the prices of fresh eggs are increased comparably, the profit level of commercial laying hen farms is abnormally high, and the number of supplemented stocks of the laying hens in each laying farm is gradually increased. However, in the period of laying eggs for the first time of laying hen breeding, the phenomenon that the diarrhea rate of the laying hens before and after the first time is high and the number of abnormal eggs is large in many laying hen farms causes the phenomenon that the laying rate of the laying hens rises slowly, the laying hens are difficult to enter the egg laying peak period, and the egg qualification rate is low, so that the economic benefit of the laying hen farms is seriously affected.
The diarrhea of the laying hens in the initial stage and the low qualification rate of eggs are related to various factors such as feed nutrition, feeding management, diseases and the like. If the nutrition of the feed is low and unbalanced, the feed can not meet the nutritional requirement of primary egg laying, and the reproductive organ function of the chicken is low, so that the abnormal eggs are increased. In addition, the feed has the problems of substandard chicken group weight, reduced body resistance, diarrhea in the early laying period, slow growth and development and the like caused by unbalanced nutrition, and the increase of the egg laying curve is influenced. According to statistics, the animal breeding cost is 60-70% and is derived from feed cost, and under the condition of certain quality of laying hens, breeding environment and breeding management, the high-quality reasonable premix and the complete feed formula are key points for improving the quality of eggs, saving the breeding cost and improving the breeding benefit. The diarrhea problem of laying hens in the initial period and the high abnormal egg rate have obvious influence on the feeding benefit, the increase of the egg rate in the whole laying period is caused, and the benefit of the whole farm is influenced. In the layer chicken of intensive cultivation, because the feed quality has certain limitation, especially in the initial laying period of the layer chicken, unreasonable feed supply can further aggravate diarrhea and the production of special-shaped eggs, and simultaneously, the laying rate and the egg weight are reduced, the body constitution and the disease resistance are reduced, the laying period is shortened, and the income of a chicken farm is influenced.

TABLE 1 complete feed formulation
(2) Analysis of influence of Hailan brown shell primary laying hens on diarrhea rate
The calculation method of diarrhea rate comprises the following steps:
observing the color and shape of the excrement of the chicken, recording the water sample excrement, the excrement which are not formed and the feed which is overfeeded as diarrhea laying hens, counting the number of the diarrhea laying hens in each test group, and dividing the number by the total number of the laying hens to obtain the diarrhea rate of the laying hens.
The effect of the premix of the present invention on diarrhea rate of the Hailan brown shell early laying hens is shown in Table 2.
TABLE 2 Effect on diarrhea Rate
As can be seen from table 2, compared with the control group, the premix of the present invention significantly reduces the diarrhea rate of the layer for laying hens at the beginning of the second week of the test by 30.4 to 33.3%, and by the third week, the premix of the present invention can reduce the diarrhea rate by 58.7 to 61%, and the average diarrhea rate is reduced by 60%, which has a very significant difference (P < 0.01) compared with the control group.
