Abstract
Description
Technical Field
[0001] The present application relates to the technical field of beef cattle breeding, and in particular to a feed additive and a preparation method thereof, and an application of the feed additive in beef cattle feed for improving beef quality. Background Art
[0002] In the process of raising beef cattle, improving meat quality has always been the focus of farmers. The growth, development and reproduction of beef cattle require adequate nutrition, and feed is the main way for beef cattle to obtain these nutrients. Reasonable feed formula can provide the energy, protein, vitamins, minerals and other nutrients required by beef cattle to ensure their normal physiological functions and growth needs. Traditional feeding methods may not meet the needs of modern consumers for high-quality meat. Feed affects the physiological functions of beef cattle. Different types of feed will have unique effects on the metabolism, immune system and digestive system of animals, which in turn affects the meat quality of beef cattle. There are many types of feed on the market, but many of them cannot effectively improve meat quality.
[0003] Therefore, there is an urgent need to develop a beef cattle feed and a feeding method thereof to improve the economic benefits and market competitiveness of beef cattle breeding. Summary of the invention
[0004] In order to solve the above technical problems, the present application provides a feed additive and a preparation method thereof and application in beef cattle feed for improving beef quality.
[0005] The present application provides a beef cattle feed additive, which specifically includes the following components in parts by weight: 4-8 parts of coix seed fermentation, 1-5 parts of traditional Chinese medicine oil, 0.08-0.20 parts of amino acids, 0.04-0.08 parts of trace elements, and 20-40 parts of carriers; The preparation method of the coix seed fermented product is as follows: taking 10 parts of coix seed powder by weight, fully soaking it in water, steaming it, and then placing it in a fermentation container, adding 0.01-0.02 parts of Lactobacillus rhamnosus and 0.001-0.003 parts of Rhizopus powder, and performing closed fermentation at a temperature of 26-35° C., and drying and sterilizing it to obtain the product; The preparation method of the Chinese medicine oil is as follows: according to weight parts, 5-15 parts of Sanguisorba officinalis and 5-15 parts of aloe vera are taken, crushed and mixed, added into 8-12 times the weight of the Chinese medicine vegetable oil and mixed evenly, treated in a constant temperature box at 60-90°C for 48-72h, and the residues are filtered out to obtain the carrier, which is composed of a mixture of biowax and castor oil in a weight ratio of 10:0.2-1.2.
[0006] The present application optimizes the nutritional structure of animals by adjusting the formula of feed additives by adopting the above-mentioned technical scheme. When used in combination with the basic daily diet and used to feed beef cattle, the intestinal microecological balance of beef cattle can be improved, the feed digestion and absorption rate can be increased, and the daily weight gain of the experimental beef cattle can be significantly increased, the feed-to-weight ratio can be reduced, and the feed conversion rate of beef cattle can be increased. In addition, the feed additives of the present application can significantly increase the back fat thickness of the experimental beef cattle, reduce the shear force of beef, and increase the fat content, thereby significantly improving the quality of beef, thereby enhancing the economic benefits and market competitiveness of beef cattle breeding.
[0007] The enzymes and probiotics in the fermented barley can help improve the balance of intestinal flora of beef cattle and increase the digestion and absorption rate of feed, which can not only promote the growth of beef cattle, but also help reduce feed waste and reduce breeding costs; through the fermentation process, the nutrients in the barley are more fully released and utilized, which can help improve the muscle fiber structure of beef cattle, make the meat more tender and juicy, and improve the taste and quality of meat; the probiotics and immune active substances in the fermented barley can enhance the immune function of beef cattle and reduce the occurrence of diseases. This not only ensures the health of beef cattle, but also reduces breeding risks.
[0008] The present application attempts to use coix seed fermented product and Chinese medicinal oil in combination to examine the effect of the combination on the feed conversion rate of beef cattle and the quality of beef; during the experiment, it was found that: the functions of coix seed fermented product and Chinese medicinal oil are complex and diverse, the immune activation and regulation mechanisms of coix seed fermented product prepared by different methods and different types of Chinese medicinal oil are different, and the immunoregulatory effect of the combination of coix seed fermented product and Chinese medicinal oil is multifaceted; therefore, the development of an efficient combination of coix seed fermented product-Chinese medicinal oil-carrier is the technical difficulty of the present application.
[0009] After many experiments, the inventor explored the synergistic mechanism between coix seed fermentation and the composite Chinese medicine oil. In the preparation method of coix seed fermentation, the synergistic fermentation of Lactobacillus rhamnosus and Rhizopus powder is used to improve the fermentation efficiency and product quality. The two strains can promote each other during the fermentation process to produce more abundant metabolites, which helps to improve the nutritional value of the feed. The Chinese medicine oil prepared by the composite of Sanguisorba officinalis and aloe vera, combined with coix seed extract, can further promote the gastrointestinal motility of beef cattle, help more comprehensive absorption of nutrients in feed, thereby improving the growth rate and feed conversion rate of beef cattle; Aloe vera contains a variety of nutrients that are beneficial to the human body. These ingredients are digested and absorbed by beef cattle and may be deposited in muscle tissue, thereby improving the taste and nutritional value of meat; Sanguisorba officinalis has the effect of improving the blood circulation of beef cattle, which helps the uniform development of muscle fibers and makes the meat more tender. At the same time, the Chinese medicinal oils of Sanguisorba officinalis and aloe vera have certain antibacterial and anti-inflammatory effects. They work together with the nutrients and probiotics in coix seed fermentation products to significantly enhance the immune function of beef cattle, reduce the risk of disease in beef cattle, and ensure the healthy growth of beef cattle.
[0010] This application uses a mixture of biowax and castor oil to form a carrier, which improves the texture and taste of the feed on the one hand: the addition of biowax can increase the lubricity of the feed, making the feed easier for beef cattle to chew and swallow; the unique aroma of castor oil can enhance the taste of the feed, stimulate the appetite of beef cattle, and thus promote their feed intake. Secondly, the carrier can improve the efficiency of nutrient absorption: castor oil is rich in unsaturated fatty acids, which can be converted into easily absorbed energy in the body of beef cattle; biowax may form a protective film in the intestine, reducing the direct contact between nutrients in the feed and digestive enzymes, thereby reducing the loss of nutrients and improving nutrient absorption efficiency. In addition, the carrier can promote intestinal health: the mixture of biowax and castor oil may have a certain laxative effect, which helps beef cattle expel toxins and waste in the intestine, maintain intestinal cleanliness, and may also promote the growth of beneficial bacteria in the intestine and inhibit the reproduction of harmful bacteria, thereby maintaining the balance of intestinal microecology.
[0011] Preferably, the beef cattle feed additive specifically comprises the following components in parts by weight: 5-7 parts of coix seed fermentation product, 2-4 parts of traditional Chinese medicine oil, 0.12-0.16 parts of amino acids, 0.04-0.08 parts of trace elements, and 20-40 parts of carriers.
[0012] Preferably, the preparation method of the coix seed fermented product is: take 20 parts of coix seed powder by weight, soak it in water for 12-24 hours, then place it in a fermentation container, add 0.012-0.018 parts of Lactobacillus rhamnosus and 0.0015-0.0025 parts of Rhizopus powder, and perform closed fermentation at a temperature of 28-32°C for 60-84 hours, and obtain it after drying and sterilization.
[0013] Preferably, the preparation method of the Chinese medicine oil is as follows: according to weight, take 5-8 parts of Sanguisorba officinalis and 12-15 parts of aloe vera, crush and mix them evenly, add them into 8-12 times the weight of the Chinese medicine vegetable oil and mix them evenly, treat them in a constant temperature box at 70-80°C for 54-66h, filter out the residues, and obtain the oil.
[0014] Preferably, the biowax is selected from one or more of beeswax, palm wax, wool wax, soybean wax, wood wax, nutshell wax, flax wax, etc. Preferably, the carrier is composed of a mixture of flax wax and castor oil in a weight ratio of 10:0.5-0.9.
[0015] Preferably, the amino acids are composed of a mixture of lysine, tryptophan, amino acids and methionine in a weight ratio of 20-30:20-30:10-16:2-8.
[0016] Preferably, the trace elements are composed of a mixture of copper sulfate, zinc oxide, sodium selenite and ferrous sulfate in a weight ratio of 10-15:10-15:5-10:1-4.
[0017] In the second aspect, the present application provides a method for preparing the above-mentioned feed additive, and the specific steps are: weighing the corresponding weight of coix seed fermentation product and compound Chinese medicinal oil respectively, adding them to the carrier, mixing and stirring evenly, and then adding the corresponding weight of amino acids and trace elements to obtain the feed additive.
[0018] In a third aspect, the present application provides a beef cattle feed, specifically comprising the following components in parts by weight: 90-100 parts of corn flour, 14-20 parts of soybean meal, 10-15 parts of soybean oil, and 3-5 parts of the beef cattle feed additive according to any one of claims 1-8.
[0019] In summary, the technical solution of this application has the following effects: This application optimizes the nutritional structure of animals by adjusting the formula of feed additives, using Lactobacillus rhamnosus and Rhizopus powder to prepare coix seed fermentation, using Sanguisorba officinalis and Aloe vera to prepare composite Chinese medicine oil, mixing biowax and castor oil in a weight ratio of 10:0.2-1.2 to form a carrier, and then preparing a feed additive in a specific proportion with a specific amount of amino acids and trace elements as raw material components. When the feed additive is used in conjunction with the basic diet to feed beef cattle, it can improve the intestinal microecological balance of beef cattle, improve the digestion and absorption rate of feed, and thus significantly increase the daily weight gain of the test beef cattle, reduce the feed-to-weight ratio, and thus increase the feed reward of beef cattle; in addition, the feed additive of this application can significantly increase the backfat thickness of the test beef cattle, reduce the shear force of beef, and increase the fat content, thereby significantly improving the quality of beef, thereby improving the economic benefits and market competitiveness of beef cattle breeding.

[0058] In Comparative Example 8: the carrier is composed of a mixture of biowax and castor oil in a weight ratio of 0.7:10.
[0059] The dosage of each raw material, the preparation method of the feed additive and the preparation method of the beef cattle feed in the above comparative example are the same as those in Example 2.
[0060] The performance test was conducted using the beef cattle feed provided in Examples 1-18 and Comparative Examples 1-8 as test objects, and the performance of the beef cattle feed after being used to feed beef cattle was tested.
[0061] Experimental method: In a beef cattle farm, select local fattening beef cattle with a body weight of 400±10kg and randomly group them. According to the nutritional needs and feeding standards of beef cattle, the beef cattle feed provided in the embodiment and the comparative example is used. The experimental cattle are fed twice a day, once at 8 am and 17 pm each day. Feed water 3 times a day, at 8 am, 12 pm and 19 pm respectively. According to the conventional management methods of the beef cattle farm, the cowshed environment is cleaned and disinfected every day; wherein, the feeding temperature is 20-28 ℃, and the feeding relative humidity is 50-60%. At the same time, the beef cattle are fed with a basic feed (prepared by mixing 95 kg of corn flour, 17 kg of soybean meal, and 12 kg of soybean oil) without adding feed additives as a blank group.
[0062] The experiment lasted 112 days, and the cattle were allowed to eat and drink freely. During this period, the feed intake and weight gain were recorded, and the average daily weight gain and feed-to-weight ratio of the cattle during the experiment were calculated. Blood was collected from the cattle one day before the end of the feeding experiment for blood index analysis. After the experiment, all meat was slaughtered according to the conventional method, and 24 hours after the carcass was acid-excreted, the longest back muscle sample was collected for meat quality index analysis.
[0063] The specific indicators for determining meat quality are: (1) Measure the back fat thickness at the cross section of the eye muscle between the 12th and 13th ribs.
[0064] (2) Use a tenderizer to measure the shear force. The smaller the shear force value, the more tender the meat is.
[0065] (3) The fat content was determined by Soxhlet extraction.
[0066] Test results: as shown in Table 2.
[0067] Table 2 Performance test results of beef cattle feed in Examples 1-17 and Comparative Examples 1-8 Combined with Table 2, by comparing the test results of Examples 1-18 with Comparative Examples 1-8 and the blank group, the beef cattle feed prepared by the technical solution of the present application, which is used to feed beef cattle, can significantly increase the daily weight gain of the test beef cattle, and the feed-to-weight ratio of the test cattle during growth and fattening is significantly reduced; in addition, the technical solution of the present application can significantly increase the back fat thickness of the test beef cattle, reduce the shear force of beef, and increase the fat content. The above test results show that the technical solution of the present application can significantly improve the feed return of beef cattle and significantly improve the quality of beef.
[0068] The feed additive of Comparative Example 1 does not contain coix seed fermentation product, and the feed additive of Comparative Example 2 does not contain the composite Chinese medicine oil, and the application effect of the prepared feed for feeding beef cattle is poor.
[0069] By comparing the test results of Examples 1-5 with those of Comparative Example 3, it can be seen that the dosage of each raw material component in the feed additive has a great influence on the feeding effect of the feed. The present application significantly improves the feed conversion rate of beef cattle and improves the quality of beef by reasonably optimizing the dosage of the raw material components.
[0070] By comparing the test results of Examples 2, 6-9 with Comparative Examples 4-5, it can be found that in the process of preparing coix seed fermentation product in Comparative Examples 4-5, the types of fermentation agents are not matched, and the application effect of the feed is not ideal; in contrast, the present application prepares coix seed fermentation product by fermenting 10 parts of coix seed powder with specifically matching 0.01-0.02 parts of Lactobacillus rhamnosus and 0.001-0.003 parts of Rhizopus powder, which can cooperate with other raw materials in the feed additive to obtain a feed additive with excellent application effect.
[0071] By comparing the test results of Examples 2, 10-14 with Comparative Examples 6-7, it can be found that in Comparative Example 6, an equal amount of cinnamon is used instead of Sanguisorba officinalis in the process of preparing the traditional Chinese medicine oil. In Comparative Example 7, the dosage of Sanguisorba officinalis and aloe vera shreds and the extraction temperature are not matched in the process of preparing the traditional Chinese medicine oil, and the application effect of the feed is not ideal. In contrast, the present application prepares the traditional Chinese medicine oil by specifically matching the types of traditional Chinese medicines to Sanguisorba officinalis and aloe vera shreds, and matching the dosage of the two traditional Chinese medicines and the extraction temperature, which significantly improves the feed conversion rate of beef cattle and improves the quality of beef.
[0072] By comparing the test results of Examples 2, 15-18 with Comparative Example 8, in the selection of carrier types, the present application significantly improves the feed conversion rate of beef cattle and improves the quality of beef by selecting a carrier composed of a mixture of bio-wax and castor oil in a weight ratio of 10:0.2-1.2.
[0073] Although the present invention has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements may be made thereto based on the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection claimed by the present invention.
