Description

Traditional Chinese medicine composition for improving laying performance of laying hens as well as preparation method and application of traditional Chinese medicine composition
Technical Field
The invention belongs to the technical field of traditional Chinese veterinary medicines, and particularly relates to a traditional Chinese medicine composition for improving the production performance of laying hens, and a preparation method and application thereof.
Background
Eggs are indispensable protein food in daily life of people, the breeding economic benefit and the quality safety of the eggs are the most concerned problems of farmers and consumers respectively, and the key to improving the breeding benefit is how to improve the production performance of laying hens and the quality of the eggs. In the traditional breeding industry, in order to improve the production benefit, farmers often add antibiotics to feed regularly for disease prevention, which invisibly increases the risk of drug residues in livestock and poultry products, and long-term use of the antibiotics often causes the appearance of drug-resistant strains, thus causing serious reduction in livestock and poultry production performance and livestock and poultry product quality and serious loss to livestock and poultry industry in China.
Therefore, new drugs or technologies are urgently needed to be researched to replace antibiotics, and adverse consequences and harm brought by the antibiotics are reduced. The traditional Chinese medicine and the preparation thereof become increasingly concerned objects by the advantages of pure nature, no toxicity, no residue, no drug resistance and the like, and are one of effective ways for solving the problems existing in the current laying hen production. The traditional Chinese medicine has the effects of tonifying middle-jiao and Qi, activating blood and dissolving stasis, is rich in various amino acids and mineral elements, and plays a great role in improving the production performance and the egg quality of the laying hens. The traditional Chinese medicine has a conditioning effect mainly by improving the physique of the laying hens, and a plurality of active ingredients have a certain antibacterial effect, so that the morbidity of common diseases such as enteritis, vitelline peritonitis and salpingitis caused by escherichia coli, salmonella and the like can be reduced, and a certain treatment effect can be achieved. Meanwhile, the traditional Chinese medicine can improve the immunity of animal organisms and improve the production performance. Modern researchers are also continuously researching and developing novel traditional Chinese veterinary medicine preparations for improving the production performance of laying hens, replacing antibiotics and reducing the loss of animal husbandry.
At present, the conventional traditional Chinese medicine extraction process generally adopts a decoction method, a reflux method and an immersion method to extract medicinal materials or decoction pieces, and has the characteristics of long extraction time and higher extraction temperature. Therefore, the active ingredients in the traditional Chinese medicine are damaged more, and the extraction yield is lower. The extracted dregs have high water content, and generally when solid wastes are treated, certain pressure is brought to environmental protection. Therefore, the invention provides a traditional Chinese medicine composition for improving the laying performance of laying hens and a preparation method and application thereof.

Example 5: clinical validation
360 300 days old new poplar black feather laying hens which are similar in weight, healthy and normal in ingestion are selected and randomly divided into 4 groups (blank control group, high dose group, medium dose group and low dose group), and each group contains 90 chickens (each group contains 3 replicates, each replicate contains 30 chickens, and each group contains 90 chickens). The pre-feeding period is 7 days, the basic ration is fed uniformly in the pre-feeding period, the laying rate, the egg weight and the feed intake of each repeated egg are recorded, and each treatment is carried out according to the recorded data. The adjustment is repeated until the difference is not obvious. The regular period starts to feed basic ration (blank control group) daily, or the traditional Chinese medicine compound extract obtained in example 2 is fed according to ration (high dose group, medium dose group and low dose group) of 0.1%, 0.05% and 0.025% feed addition for 10 days continuously, and then the basic ration is fed for 20 days, and the three periods are repeated for 30 days to obtain 90 days in total. The experimental design is shown in table 2.
Table 2 experimental groups and diet treatment

Figure BDA0003404514480000071
During the test period, the number of eggs laid, the total egg weight, the number of broken soft eggs, the number of sand shell eggs and the number of dead and culled chickens on the day are recorded by taking the repetition as a unit every day. The laying rate and the average egg weight are calculated by taking the repetition as a unit every day, and the soft egg breaking rate, the eggshell egg rate, the average daily feed intake and the feed-egg ratio are calculated by taking the repetition as a unit every five days.
Laying rate (%) < total number of eggs laid per day/(number of chickens participating in production per day) × 100%
Average egg weight (g/egg) — total egg weight per day/total egg count per day
The soft egg breaking rate (%) is the total number of soft eggs broken every five days/the total number of eggs laid every five days x 100%
The eggshell egg rate (%) -, the total eggshell egg number per five days/the total egg number per five days × 100%
The test results show that
(1) Compared with the blank control group, the medium dose group greatly improves the laying rate of the laying hens at 30 days and 90 days of the test (P <0.01 (Table 3).
Table 3 laying rate (%)

Note: indicates that the difference was very significant compared to the control group (P < 0.01).
(2) The medium dose group significantly increased the feed intake of the layers (P <0.05) at day 90 compared to the blank control group (table 4).

Note: data in the table are mean ± sd, with data in the same column being annotated with no identical letters to indicate significant differences (P < 0.05).
(3) Compared with a blank control group, the medicine groups both significantly reduce the egg breaking rate of the laying hens (P <0.05), wherein the egg breaking rate of the high-dose group and the middle-dose group is significantly reduced (P <0.01) (Table 5).

Note: indicates significant difference (P <0.05) compared to the blank control group, and indicates very significant difference (P <0.01) compared to the blank control group.
(4) Each test group significantly reduced the eggshell egg rate (P <0.05) of the layers compared to the blank control group, wherein the medium and low dose groups significantly reduced the eggshell egg rate (P <0.01) (table 6).

Note: indicates significant difference (P <0.05) compared to the control group, and indicates very significant difference (P <0.01) compared to the blank control group.
(5) The high and medium dose groups significantly improved eggshell strength (P <0.05) of the laying hens at 60 days compared to the control group (table 7).

(6) Compared with a blank control group, the high-dose group remarkably improves the CAT content (P <0.05) in the serum of the laying hen at 30 days, and the high-dose group and the medium-dose group remarkably improve the CAT content (P <0.05) in the serum of the laying hen at 60 days. The high dose group significantly reduced the MDA content in the hen serum at 90 days (P <0.05) compared to the blank control group (table 8).
