Description

Technical Field

[0001] The present invention relates to the technical field of feed additives, and particularly relates to a functional additive Qiwei Zhengdan Powder and its application. Background Art

[0002] Eggs are one of the important sources of protein for people. It has important practical significance to improve and enhance the laying performance and egg quality of laying hens and other production traits. Laying rate, egg weight, duration of peak laying period, egg quality, eggshell quality, and feed-to-egg ratio are all the main economic traits of laying hens. However, excessive pursuit of egg production quantity during the peak laying period will affect the physical condition of laying hens, resulting in a decline in egg quality in the later laying period, specifically manifested as an increase in cracked eggs, soft eggs, sandy eggs, and sun eggs, a shorter duration of the peak laying period, a decrease in eggshell strength, a lighter eggshell color, and a duller color, seriously affecting the market sales of eggs.

[0003] Due to the extremely high nutritional requirements of laying hens during egg production and the extreme sensitivity of the reproductive system to changes in internal and external environmental factors, intestinal health is extremely important for the laying performance of laying hens. In the later laying period of laying hens, some adverse changes or weakening may occur in the intestinal structure and function. Mycoplasma synoviae (MS) of the reproductive type in laying hens can cause problems such as sun eggs, sandy eggs, and cracked eggs. This mycoplasma mainly affects the reproductive system of laying hens, resulting in a decline in eggshell quality and a decrease in laying rate; it usually appears during the peak laying period, manifested as an increase in soft-shelled eggs, cracked eggs, sun eggs, and sandy eggs, and a decrease in laying rate. Antibiotics such as tylosin and florfenicol can effectively treat synovial mycoplasma infection, and when combined with vitamin and mineral supplements, they can enhance immunity. However, antibiotics are prone to drug resistance, and the residue amount is likely to exceed the standard, affecting the renal function of the chicken flock, resulting in kidney swelling, etc., seriously endangering the health of the chicken flock. Currently, most antibiotics cannot be used in laying hen production. Adding Chinese herbal medicine components can play a role in alleviating this, thereby improving and enhancing the production performance and egg quality of laying hens in the later laying period, etc.

[0004] Therefore, it is of great significance to research and obtain a functional additive of Chinese herbal medicine components to reduce the decline rate of eggshell quality, improve the laying qualification rate, and extend the peak laying period. Summary of the Invention

[0036] Comparative Example 1

[0037] The Astragalus membranaceus and Ligustrum lucidum in Example 1 are omitted, and the Schisandra chinensis is changed to 2 parts, and other conditions are the same as those in Example 1.

[0038] Comparative Example 2

[0039] The Leonurus japonicus and Rehmannia glutinosa in Example 1 are omitted, and the Astragalus membranaceus is changed to 1 part, and other conditions are the same as those in Example 1.

[0040] The functional additives in Examples 1 - 3 and Comparative Examples 1 - 2 are added to the basal diet to prepare laying hen feed, and the laying hens are fed, and the production performance indexes and egg-laying performance indexes of the laying hens are analyzed.

[0041] The basal diet referred to the feed standards for laying hens in NRC (1994) and the feeding standards for laying hens in China's NY / T 33 - 2004. The mass contents of each component in the basal diet were as follows: corn 63%, wheat bran 2.5%, soybean meal 23.5%, methionine 0.09%, calcium powder 9.7%, calcium hydrophosphate 0.45%, table salt 0.3%, sodium bicarbonate 0.08%, phytase 0.03%, trace mineral element premix 0.2%, multivitamin premix 0.03%, choline chloride 0.12%. The trace mineral element premix provided 90 mg of iron, 12 mg of copper, 120 mg of manganese, 100 mg of zinc, 0.3 mg of selenium, and 1 mg of iodine per kilogram of basal diet; the multivitamin premix provided 12000 IU of VA, 6000 IU of VD, 18 IU of VE, 215 mg of VK3, 3 mg of VB1, 18 mg of VB2, 45 mg of VB6, 18 μg of VB 12 18 μg, 1.8 mg of folic acid, 30 mg of niacin, and 13.5 mg of calcium pantothenate per kilogram of diet.

[0042] The functional additives in Examples 1 - 3 and Comparative Examples 1 - 2 were respectively mixed evenly with the basal diet. The addition amount of the functional additive in the basal diet was 0.8 wt%, and the laying hen feeds corresponding to Examples 1 - 3 and Comparative Examples 1 - 2 were obtained respectively.

[0043] 1500 Hy - line Brown laying hens at 120 days of age were selected in a chicken farm. The laying hens had not used egg - increasing drugs. The laying hens were cage - raised, and the temperature and humidity of the chicken house were adjusted using a water curtain. They were fed and watered freely. They were raised and immunized according to the conventional feeding operation procedures and immunization programs. The laying hens were randomly divided into 5 groups, with 300 hens in each group. Each group was fed the laying hen feeds of Examples 1 - 3 and Comparative Examples 1 - 2 respectively, and the test period was 60 days. After the test, the growth performance index (feed - to - egg ratio) and egg - laying performance indexes (the rates of abnormal eggs such as sandy - shelled eggs, sun - shaped eggs, soft eggs, and cracked eggs, and the duration of the peak egg - laying period) of the laying hens were statistically analyzed, and the rate of abnormal eggs was tested again after 3 months.

[0044] Among them, the feed - to - egg ratio = feed consumption / total egg production weight; the rate of abnormal eggs (%) = (the number of sandy - shelled eggs + the number of sun - shaped eggs + the number of soft eggs + the number of cracked eggs) / total number of eggs produced × 100%; the duration of the peak egg - laying period was the egg - laying time when the laying rate of the laying hens exceeded 90%.

[0046]

[0047] The present invention reasonably selects the Chinese herbal medicine components Astragalus membranaceus, Schisandra chinensis, Ligustrum lucidum, Leonurus japonicus, Rehmannia glutinosa, Gardenia jasminoides, and Glycyrrhiza uralensis, and strictly controls the proportions of each component to obtain the functional additive Qiwei Zhengdan Powder, which enables the rate of abnormal eggs such as sand eggs, sunny-side-up eggs, soft eggs, and cracked eggs not to exceed 1.5%, the peak laying period to be longer than 255 days, the rate of abnormal eggs not to exceed 1.7% after 3 months, and the feed-to-egg ratio not to exceed 2.03. Changing the components or the dosages of the components in the functional additive of the present invention will reduce the growth performance and egg-laying performance of laying hens.

[0048] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
