Description

Technical Field

[0001] The present invention relates to the technical field of broiler feed processing, and particularly relates to a broiler feed containing soy isoflavones, a preparation method thereof, and an application thereof. Background Art

[0002] In the prior art, feeds are generally prepared with corn, soybean meal, soybean oil, corn gluten meal, and DDGS (DDGS is the trade name of distillers dried grains with soluble solids, that is, dried distillers grains containing soluble solids, which is a mixture of dried distillers grains (DDG) and soluble dried distillers grains filtrate.) for raising poultry, such as raising broilers. Among them, the cost and dosage of soybean meal are both large, resulting in a relatively high overall feed cost. However, if the dosage of soybean meal is reduced and replaced with other ingredients, such as increasing the amount of corn, the dosage of antibacterial and disease-preventing agents needs to be increased simultaneously, and the feed safety will be affected. Therefore, the dosage of soybean meal cannot be significantly reduced, and the feed cost cannot be well controlled. Summary of the Invention

[0003] Aiming at the deficiencies in the prior art, the present invention provides a preparation method of a broiler feed containing soy isoflavones, which solves the problems of large dosage of soybean meal and high feed cost in the prior art.

[0004] According to an embodiment of the present invention, a preparation method of a broiler feed containing soy isoflavones, in the feed provided by this method, soy isoflavones are used to partially replace soybean meal, which can reduce the overall cost, thus solving the problems of large dosage of soybean meal and high feed cost in the prior art; the specific preparation method includes: mixing corn, flour, soybean meal, protein powder, DDGS, fine stone powder and / or bentonite, calcium hydrogen carbonate, choline chloride, table salt, baking soda, premix, methionine, lysine, threonine, valine, tryptophan, isoleucine, calcium formate and soy isoflavones evenly, spraying soybean oil during the mixing process, and continuing to mix for 2 - 5 minutes after the spraying of soybean oil is completed to obtain the broiler feed.

[0005] Further, the weight ratio of soy isoflavones is 0.6%, and the weight ratio of soybean meal is 24.6% or 29.15%.

[0006] Further, the soy isoflavones are obtained by fermentation.

[0007] Further, the daidzein content of the soy isoflavones is 97 - 98%.

[0008] According to the embodiment, a broiler feed containing soy isoflavones obtained by the above method is also provided.

[0009] According to the embodiment, the application of the above broiler feed containing soy isoflavones is also provided, which is applied to the raising of broilers aged 1 - 21 days.

[0010] According to an embodiment, there is also provided an application of the above-mentioned broiler feed containing soy isoflavones in the feeding of broilers aged 22 - 42 days.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] The provided method replaces part of the soybean meal by increasing soy isoflavones, and at the same time can be applied to the feeding of broilers of different ages, ensuring the normal growth of broilers throughout the growth period, and at the same time reducing the overall feed cost, solving the problems of large consumption of soybean meal and high feed cost in the prior art. Specific Embodiments

[0013] The technical solutions in the present invention will be further described below in conjunction with embodiments.

[0014] This embodiment provides a preparation method of a broiler feed containing soy isoflavones, and the specific components are shown in Table 1 below:

[0015] Table 1

[0016]

[0017] Note: In the above table, the protein powder is corn protein powder, and the soy isoflavones are prepared by the company using a biological fermentation method with the content of daidzein in soy isoflavones as the target of 97 - 98%.

[0018] In the process of preparing the feed, the components in the above table are stirred and mixed in proportion. Among them, the soybean oil is added in a spraying manner during the stirring and mixing process. After the addition of the soybean oil is completed, the stirring and mixing are continued for 2 - 5 minutes to obtain the feed. The feed provided in the 1 - 21 - day - old stage is particle - broken feed, and the feed provided in the 22 - 42 - day - old stage is pellet feed. In the conventional broiler feed, a large proportion of soybean meal is required to ensure the normal growth of broilers. The feed provided by the present invention can add soy isoflavones to replace part of the soybean meal on the basis of the conventional broiler feed. That is, by adding 6 kg of soy isoflavones, the consumption of 24 kg of soybean meal can be reduced, and the feed cost can be reduced by 29.7 yuan, about 30 yuan (calculated at 3300 yuan per ton of soybean meal). Moreover, the broiler feed provided by the present invention can be provided to broilers of different age segments and can meet the growth requirements.

[0019] Using the broiler feeds provided in Experiment 1, Experiment 2, and Experiment 3 for experiments, the cumulative feed intakes at 21 days old and 42 days old were statistically analyzed to calculate the average daily feed intakes in the 1 - 21 - day - old and 22 - 42 - day - old stages. Sampling and weighing 30% of the chickens randomly at 21 days old and weighing the whole flock at 42 days old in units of weight were used to calculate the average weight and feed - to - meat ratio. The health status of the chicken flock was observed every day, the number of dead chickens was recorded in units of replicates, and the weights of the dead chickens were recorded to calculate the survival rate, mortality rate, feed - to - meat ratio, and European efficiency index, etc. The results are as follows:

[0020] Table 2

[0021]

[0022] Note: 1. Feed to weight ratio (including mortality and culling) = Feed consumption / (Final body weight - Initial body weight)

[0023] 2. Different lowercase letters in the superscript of data in the same row indicate significant differences (P < 0.05), while the same letter or no letter indicates no significant differences (P > 0.05).

[0024] Table 3

[0025]

[0026] Note: Different lowercase letters in the superscript of data in the same row indicate significant differences (P < 0.05), while the same letter or no letter indicates no significant differences (P > 0.05).

[0027] As can be seen from Table 2 and Table 3, adding soybean isoflavone to replace soybean meal in the feed has a significant effect on the body weight, average daily gain and feed to weight ratio of broilers from 1 to 21 days old (P < 0.001). The results show that the body weight and average daily gain of the control group, experimental group 1, experimental group 2 and experimental group 3 are significantly higher than those of the positive control and negative control, and the highest is in experimental group 1; at the same time, the feed to weight ratio of the control group, experimental group 1, experimental group 2 and experimental group 3 is significantly lower than that of the positive control and negative control. There are no significant differences in average daily feed intake, survival rate, mortality and European benefit index (P > 0.05).

[0028] As can be seen from Table 3, there is no significant difference in the slaughter rate between each experimental group and the control group (P > 0.05), among which the slaughter rate of experimental group 3 is relatively high, and the slaughter rate of the positive control group is the lowest (P > 0.05).

[0029] Considering indicators such as market weight, feed to weight ratio and European benefit index comprehensively, the effect of experimental group 1 is the best, followed by the control group and experimental group 2.

[0032] Table 5

[0033]

[0034] Referring to Tables 4 and 5 and considering the above test results comprehensively, (1) The growth performance of the three low-protein test groups is overall better than that of the three control groups. Among them, the growth performance of Test Group 3 (basal diet - 24 kg soybean meal + 6 kg soy isoflavone) is the best, followed by Test Group 2 and Test Group 1; (2) Adding soy isoflavone can promote the growth, development, immunity and antioxidant performance of broilers; (3) Adding soy isoflavone can improve the intestinal microbial composition and function, and adding 6 kg soy isoflavone has a better effect on intestinal health.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
