Description

Technical Field

[0001] The invention relates to the technical field of feed preparation, and in particular to a method for preparing broiler feed containing anti-stress ingredients. Background Art

[0002] Chicken meat is soft and easily digested and absorbed by the human body. Drinking chicken soup and eating chicken often can not only supplement the nutrition of elderly diabetic patients, but also control the development of the disease. It is suitable for people with weak body, insufficient blood, and malnutrition, and is suitable for winter tonic. Faced with the increasing demand in the broiler market, farmers achieve higher economic income by raising broilers. As people have higher and higher requirements for meat products, green, healthy and safe food has become more and more important. Therefore, farmers are required to strictly demand themselves in the process of raising broilers, because raising broilers is inseparable from chicken feed. The chicken feed used not only allows the chicken to grow quickly, but also ensures the taste and nutrition of the chicken. At the same time, the chicken feed must be able to improve the physique of broilers, enhance the immunity of chickens, prevent the occurrence of chicken diseases, and reduce the mortality rate, so as to truly achieve high yield and high quality of broilers, so as to bring stable economic benefits to the farmers themselves.

[0003] In the prior art, in order to solve the oxidative stress effect in the broiler breeding process, anti-stress additives are added to the feed. The anti-stress additives are mainly various vitamins, trace elements, etc., which are used to regulate the activity of insulin and immune response to improve the meat and egg production of livestock. Directly adding anti-stress additives to the feed is prone to uneven mixing, resulting in different contents of anti-stress additives in the feed, and the intake is difficult to control.

[0004] The invention patent with publication number: CN110692853A discloses a broiler feed, which is mainly composed of meal, limestone powder, fish meal, corn alcohol grains, calcium hydrogen phosphate, salt, biological additives and nutritional additives. The broiler feed of the present invention has a reasonable formula and rich nutrition. The biological additive contains Chinese medicinal ingredients, which can improve the immunity of broilers and effectively improve the growth rate of broilers, so that the survival rate of broilers is high and the growth is fast. The meat of the fed broilers is delicious, and the preparation method of the broiler feed is simple, has no toxic side effects, and is safe and reliable.

[0005] The invention patent with the publication number CN103504149B discloses a starter feed for white-feathered broilers, whose components are mixed by weight as follows: corn, flour, corn oil, soybean meal, brewer's yeast powder, corn protein powder, hemoglobin powder, stone powder, calcium hydrogen phosphate, salt, 70% lysine sulfate, 98% methionine, 98% threonine, phytase, complex enzyme, broiler complex vitamins, broiler complex trace elements, 60% choline chloride, mold adsorbent, Xinlaiwang, antioxidants, and Yijunle. The starter feed for broilers does not contain any prohibited ingredients. While improving disease resistance, it can meet the needs of rapid growth and development of white-feathered broiler chicks in the early stage and reduce the occurrence of stress reactions in the later stage. The broilers fed fully meet the standards for export to Japan, South Korea and other countries.

[0006] In the prior art, anti-stress additives are added during the preparation of feed, which can improve the mixing effect of the feed so that the anti-stress additives and the feed can be fully mixed; however, since the feed and the anti-stress additives are directly mixed, the feed is in contact with air for a long time, which can easily cause oxidation of the feed and affect the use effect.

[0066] Embodiment 4

[0067] The present embodiment discloses a method for preparing an anti-stress broiler feed. The broiler feed comprises a basic feed and an anti-stress additive. The basic feed comprises 50 parts of corn, 10 parts of wheat, 5 parts of bran, 20 parts of soybean meal, 5 parts of fish meal, and 6 parts of pectin; the anti-stress additive comprises 2 parts of yeast powder, 3 parts of calcium hydrogen phosphate, 1 part of eggshell powder, 0.2 parts of sodium chloride, 0.1 parts of vitamin C, 0.2 parts of vitamin E, 1 part of guanidine acetic acid, 0.3 parts of KCl, 0.1 parts of amino acids, and 0.1 parts of minerals.

[0068] During preparation, the basic feed and the anti-stress additive are mixed as a whole and then pelletized.

[0069] In actual use, 500 healthy white-feathered broilers of basically the same weight at 10 days of age were randomly divided into experimental groups 1-4 and a control group, and raised in the same chicken house environment. The experimental groups 1-4 were fed with the feed prepared in Examples 1-4, respectively; the control group was fed with ordinary broiler feed, and the control group feed was selected from Chia Tai Broiler Feed 510.

[0072] Embodiment 5

[0073] This embodiment is substantially the same as the first embodiment, except that, in this embodiment, the anti-stress additive further comprises 3-4 portions of yucca extract.

[0074] In this embodiment, 3.5 parts of yucca extract are used, the total dissolved yucca solids TDS in the yucca extract is ≥40%, saponin (Saponin) is ≥10.8%, and the moisture is ≤8%; TDS is an indicator for detecting how much yucca extract is contained in the yucca product, and the amount of total soluble solids contained in the sample is expressed as a mass percentage, which can be determined in the laboratory through sample water solubility test, evaporation test or spectrophotometry.

[0075] The saponins in yucca extract can reduce the surface tension in the intestine and improve the emulsification capacity of nutrients, thereby improving the digestion and absorption rate of nutrients in the intestine, especially the absorption rate of fat and fat-soluble substances. At the same time, saponins can form complexes with sterols on the cell membrane, thereby effectively improving the permeability of the intestinal mucosa and facilitating the absorption of nutrients. It can also improve the structure of the intestinal mucosa of animals, promote the growth and development of the intestinal mucosa, and enhance the absorption function of the intestine.

[0076] The added yucca extract has a broad-spectrum antibacterial effect, which can significantly inhibit the reproduction of protozoa and other harmful bacteria, promote the proliferation of beneficial bacteria, and maintain the balance of intestinal flora; it can also significantly improve the absorption and utilization rate of nutrients, improve animal immunity, and reduce the incidence of diseases. Therefore, it can replace antibiotics, maintain animal health, and improve animal production performance. It is not absorbed by the gastrointestinal tract of animals and will not remain in meat and tissues. It is a green and safe feed additive.

[0077] In actual use, the feed prepared in Example 5 was used to raise 50 healthy white-feathered broilers of substantially the same weight at 10 days old in the same chicken house environment, and the control group was fed with the feed prepared in Example 1; the effect on the production performance of broilers is shown in the following figure. Figure 2 As shown. Figure 2 It can be seen that the feed with added yucca extract has a better promoting effect on the growth of broiler chickens. Figure 2 In the table, the same shoulder letters indicate no significant difference, otherwise it indicates a significant difference.

[0078] Although the preferred embodiments of the present invention have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0079] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
