Technical Field
The invention relates to the technical field of cultivation, and particularly relates to a composition for improving the production performance of laying quails and application thereof.
Background
Quail (Coturnix) is small and round, has dark and dark feathers, and is usually slightly different between male and female. The small brown color band has obvious straw yellow spear stripes and irregular stripes, and the male and female bodies have reddish brown and black transverse stripes. The male chin is dark brown, and the midline of the larynx bends upwards to the ear pinna and is tightly attached to the yellowish necklace. The yellowish eyebrows contrast significantly with the brown tops of the heads and the lines of the eyes. Female birds also had similar patterns but the control was not obvious.
Quail eggs are considered as 'ginseng in animals' and are suitable for being eaten as nourishing dietary therapy products frequently, and are called 'good in egg' because of having unique nutrition. The egg quail is the main part of laying quail eggs, and the prior art is less to the research of the production performance of egg quail, leads to egg quail production performance relatively poor, can't satisfy social demand.

The invention also improves the application of the feed additive in improving the production performance of the laying quails. When the feed additive is added into basic ration of egg-laying quails, the ability of resisting the environment in the growth process of the egg-laying quails can be obviously improved, the immunity of the egg-laying quails is improved, and meanwhile, the production performance of the egg-laying quails can also be improved.
Preferably, the feed additive is used for improving the production performance of the laying quails, wherein the production performance comprises average egg weight, number of stockings, material-egg ratio and death rate. The application of the feed additive can obviously improve the production performance of laying quails.
Specifically, the feed additive is applied to improving the production performance of the laying quails, and is added into the basic ration of the laying quails. More specifically, the addition amount is 3-8% of the mass of the basic ration.
Compared with the prior art, the invention has the following beneficial effects:
the invention provides a feed additive for improving the production performance of laying quails, which comprises the following substances in parts by weight: 0.01-0.05 part of xylooligosaccharide, 0.06-0.1 part of mannooligosaccharide, 1-3 parts of bacillus subtilis, 1-3 parts of bacillus licheniformis, 0.5-2 parts of compound lactic acid bacteria and 10-15 parts of hermetia illucens dry insect powder; the black soldier fly has high protein content and can be used as an excellent source for animal protein supplement, and a plurality of antibacterial peptides can be generated in the black soldier fly, so that the black soldier fly and oligosaccharides such as xylo-oligosaccharide and mannooligosaccharide can synergistically enhance the immunity of the laying quails; in addition, the oligosaccharide substances can improve the quantity of beneficial bacteria in animal intestinal tracts, but the effect is not obvious, and the invention selects the oligosaccharide substances with specific molecular weights and additionally adds some compound lactic acid bacteria, bacillus subtilis and bacillus licheniformis in vitro, so that the beneficial bacteria can be planted in the animal intestinal tracts, the quantity of the beneficial bacteria in the animal intestinal tracts is obviously improved, and the invention is beneficial to improving the immunity of the laying quails.

Experiment of quail: self-matched yellow feather male and female lines capable of laying eggs for 1 month.
The experimental method comprises the following steps: 49000 feather-laying quails in the same house are randomly divided into a 25000 feather test group and a 24000 feather control group, the test group adds the feed additives of the above examples 1 to 3 into basic daily ration, the addition amount is 5 percent of the mass of the basic daily ration, and the control group feeds the basic daily ration. The pre-test period is 10 days, the trial period is 49 days, and the feed consumption, the egg production, the feed-egg ratio, the egg production rate and the death and culling rate of each group of the ten thousand feathers per week and the feed-egg ratio, the death and culling rate and the profit of each group of the whole period are calculated by taking the week as a unit. Conventional breeding management is adopted, and each group with diseases is treated according to symptoms. Data were statistically analyzed using SPSS software and data are presented as "mean ± standard deviation".
The results of the experiment are shown in table 1, and the data in table 1 were analyzed: the feed additive of the group of the embodiment is added into basic ration, the full-period feed-egg ratio and the week feed-egg ratio of the laying quail are respectively reduced by 3.45%, 3.94% and 3.45%, and the requirement of reducing the feed-egg ratio by 3% in the project contract index is met. The weekly mortality rate of the example groups is reduced by more than 15%, the full-period mortality rate is reduced by more than 10%, and the requirements that the project index mortality rate is reduced by more than 10% are met. The full-season ten-thousand-feather profit of the embodiment group is improved by about 15 percent, and the requirement that the project index is higher than 10 percent is met.
In the experimental period, the control group has 2 times of medication, the cost is 420 yuan, the costs of the examples 1 to 3 are respectively 170 yuan, 180 yuan and 150 yuan, because the antibiotics are forbidden to the egg-laying poultry, the Chinese herbal medicine preparations are adopted, the cost of the medicines of the examples 1 to 3 is respectively reduced by 61.9 percent, 63.09 percent and 64.3 percent compared with the control group, and the requirement of reducing the contract requirement by more than 60 percent is achieved. The weight of defective eggs in the example group is reduced by 33.37 percent, 34.55 percent and 40 percent respectively compared with the control group, which indicates that the eggs in the control group have more fallopian tube diseases than the control group.
TABLE 1
Experimental example 2
Selecting the egg quails fed in the examples 1 to 3 and the control group, taking 0.1g of cecal content under aseptic condition, washing the cecal content clean with sterile normal saline, then sucking the cecal content dry with filter paper, placing the cecal content in a sterilized glass homogenizer filled with glass beads, adding a small amount of sterile normal saline (0.85% NaCl) for homogenizing, fixing the volume to 1mL after homogenizing, performing gradient dilution by taking the homogenized sample as a stock solution, selecting the dilution degree of bacterial colonies, respectively coating 0.1mL of the cecal content on a BS culture medium (selected bifidobacterium), an LBS culture medium (selected lactobacillus), an EMB culture medium (selected enterobacteria) and EC enterococcus (selected enterococcus), coating 3 plates on each group, performing inverted culture at 28 ℃ for 24 hours, and calculating the average bacterial colony number (X) of the same dilution degree by using a colony counter. CFU/g samples were calculated using the CFU formula, and the calculation results were expressed in logarithmic form (logN/g), and the results are shown in Table 2. The CFU calculation formula is as follows:
CFU/g specimen ═ X/0.1 × dilution factor × 1/specimen weight (g).
TABLE 2
As can be seen from Table 2, the number of bifidobacteria and lactobacilli in intestinal tracts of the laying quails of the example group is remarkably increased, which shows that the feed additive provided by the invention can regulate the structure of intestinal flora of the laying quails, improve intestinal microenvironment, improve the immunity of the laying quails, and also remarkably improve the capability of the laying quails in digesting and absorbing nutrient substances in the feed, thereby improving the production performance of the laying quails.
Experimental example 3
The egg quails fed in examples 1 to 3 and the control group were selected, 10 eggs were randomly selected from each group, weighed on empty stomach, slaughtered according to a conventional method, bursa and spleen were taken and weighed, and immune organ index was calculated. The results are shown in table 3, and it can be seen from table 3 that the feed supplement of the present invention can increase spleen and bursa of fabricius of laying quails, indicating that it can significantly enhance immune status of laying quails.
Immune organ index is the wet weight of immune organ (mg)/body weight (g).
