Description

Technical Field

[0001] This application relates to the field of feed processing technology, specifically to a quail feed that can improve egg production rate and egg quality, and a method for preparing the same. Background Technology

[0002] Quail eggs, also known as quail bird eggs or quail ova, are nearly round in shape and small in size, generally weighing only about 10g. Quail eggs contain a complete range of amino acids, are rich in lecithin and cephalin, and have a low cholesterol content. Compared to chicken eggs, they are more easily absorbed by the human body, and therefore, due to their extremely high nutritional value, they are known as "ginseng among animals."

[0003] Studies show that quails typically begin laying eggs at 40 days old and can continue to do so for more than 10 months. Although the scale of quail farming in my country is gradually expanding and farming conditions have improved significantly, extending the egg-laying cycle and increasing egg production remains a pressing technical challenge.

[0004] Therefore, there is an urgent need in the field for a quail feed that can solve the above problems, hence this application is filed.

[0187] Inoculum: 0.1 parts Bacillus subtilis and 0.1 parts Escherichia coli; wherein the viable count of each inoculum is approximately 1.0 × 10⁻⁶. 8 cfu / g (9.0×10) 7 cfu / g -1.1×10 8 cfu / g).

[0188] The above-mentioned feed matrix, eggshell fortifier, sodium chloride, vitamins, amino acids, sugars, and microbial agents are mixed evenly and then crushed to obtain the feed product.

[0189] Among them, the components used in formulas 6-9 are all from the same batch.

[0190] Formula 13

[0191] It is basically the same as formula 5, except that the lactose metabolism rate of the tested lactobacilli is 25%.

[0192] Formula 14

[0193] It is basically the same as formula 5, except that the lactose metabolism rate of the lactobacillus was 35%.

[0194] Formula 15

[0195] It is basically the same as formula 5, except that the lactose metabolism rate of the lactobacillus was 30%.

[0196] In this application, the lactose metabolism rate of Lactobacillus can be calculated as follows: 100 μl of 1×10 9 CFU / ml bacterial culture was inoculated into 2.5ml of sterile MRS broth containing lactose and incubated at 37℃ for 24h. The remaining lactose content in the culture medium was determined by the anthrone colorimetric method. The formula for calculating the lactose metabolism rate is as follows:

[0197] Lactose metabolism rate = (1-P1 / P0)×100%, where P0 and P1 are the amount of residual lactose (g / mL) in the broth culture medium at 0h and 24h, respectively.

[0198] In addition, this experiment was conducted using the same components as formulations 1-3. The experimental results are shown in Table 2.

[0199] Table 2. Experimental Results on the Relationship between Feed Consumption and Quail Egg Production

[0200] Group Egg-to-feed ratio (%) Formula 1 42.0 Formula 2 41.4 Formula 3 40.9 Formula 9 43.3 Formula 10 43.8 Formula 11 44.2 Formula 12 42.7 Formula 13 45.1 Formula 14 44.5 Formula 15 47.0 control group 42.2

[0201] This application uses the egg-to-feed ratio to measure the relationship between quail feed intake and egg production rate; the higher the egg-to-feed ratio, the higher the feed conversion rate. According to the results in Table 2, comparing formulas 13-15, when using the components of formula 5 of this application, and with a lactose metabolism rate of 30% for its Lactobacillus, the egg-to-feed ratio is higher. However, comparing formulas 15 and formulas 9-11, although their Lactose metabolism rates for Lactobacillus are all 30%, there is still a significant difference in the egg-to-feed ratio, proving that each strain in the microbial agent is indispensable for achieving the desired technical effect.

[0285] Example 16

[0286] Female Korean quails aged 50 days were caged throughout their lifespan, with no restrictions on their food or water intake. They were grouped into groups of 30 quails each, based on the feeds prepared in Examples 1-15 and Comparative Examples 1-5.

[0287] During the experiment, the temperature was controlled at 25±2℃, and the quail were raised for 30 days. Egg production rate and feed conversion ratio were calculated according to the method described in this application. Egg weight and eggshell strength were calculated using existing methods. The experimental results are shown in Table 3, where the egg weight and eggshell strength are the average values ​​of 10 randomly selected quail eggs.

[0288] Table 3 evaluates the performance indicators of the feeds prepared in Examples 1-13 and Comparative Examples 1-4.

[0289]

[0290]

[0291] Based on the experimental results in Table 3, the following preliminary conclusions can be drawn:

[0292] First, the feed provided in this application is safe, and no quails died after consuming the feed during the experiment.

[0293] Second, the quails fed with the feed provided in the embodiments of this application have a significantly higher egg production rate compared with the quails fed with the feed of the prior art (Comparative Example 1, Comparative Example 2), and the data are statistically significant.

[0294] Third, the quails fed with the feed provided in the embodiments of this application had a significantly higher feed conversion ratio than the quails fed with the feeds in Comparative Examples 1-4, and the data were statistically significant. Among them, Comparative Examples 3 and 4 were cases where monosaccharides and polysaccharides were missing in the carbohydrate components, respectively, indicating that both monosaccharides and polysaccharides in component A have a certain promoting effect on the feed conversion ratio.

[0295] Fourth, the quails fed the feed provided in the embodiments of this application had significantly higher egg weights compared to the quails fed the feed of the prior art (Comparative Example 1), and the data was statistically significant. Furthermore, comparing Examples 4-6 with Examples 1-3 and 7-15, the egg weights obtained in Examples 4-6 were significantly lower than those in other examples, while the content of polar amino acids (glutamic acid) in Examples 4-6 exceeded 30%. Therefore, this application should try to control the proportion of polar amino acids in the amino acid composition to be no higher than 30% when formulating the feed.

[0296] Fifth, the quails fed the feed provided in the embodiments of this application have significantly higher eggshell strength compared to quails fed the feed of the prior art (Comparative Example 1), and the data is statistically significant. Furthermore, comparing Examples 4-10 with Examples 1-3 and 11-15, the eggshell strength of Examples 4-10 is significantly lower than that of the other examples, while the content of polar amino acids (glutamic acid) in Examples 4-6 exceeds 30%, and the ratio of monosaccharides to polysaccharides in Examples 7-10 does not fall within the range of 1:2-1:5. Therefore, when formulating the feed, this application should try to control the proportion of polar amino acids in the amino acid component to be no higher than 30%, and the ratio of monosaccharides to polysaccharides in the carbohydrate component to be between 1:2 and 1:5.

[0297] Sixth, the egg production rate and egg-to-feed ratio of Examples 13-15 are superior to those of the prior art and other examples, which also shows that the preparation method of the above components proposed in this application is superior to the preparation method of direct mixing.

[0298] Seventh, the egg-to-feed ratio in Examples 11-12 is better than that in Example 2, indicating that the microbial agent components in Examples 11-12 can further optimize the egg-to-feed ratio of the product, making it more suitable for promotion and application;

[0299] Eighth, comparing Example 2 and Comparative Example 5, when the feed matrix is ​​only corn, the egg production rate, feed conversion ratio, egg weight, eggshell strength and other indicators of the finished feed are significantly lower than those of the examples in this application. This shows that the feed matrix components in this application have a synergistic effect with other components.
