Description

Technical Field

[0001] The invention relates to a beef cattle feed and also to a method for preparing the beef cattle feed, belonging to the technical field of feed and its preparation. Background Art

[0002] Beef has high protein content and low fat content. It is also rich in creatine that promotes muscle growth, vitamin B6 that enhances immunity, carnitine that promotes fat metabolism, and hemoglobin iron that is easily absorbed by the human body. It has high nutritional value. With the development of social economy, people's demand for beef is getting higher and higher. At present, the per capita consumption of beef is second only to pork and is showing a steady growth trend. It has become one of the common meats for consumers. The gradual increase in beef consumption has driven the development of beef cattle breeding industry, and the breeding volume of beef cattle is increasing.

[0003] Beef cattle are cattle used for meat, which are mainly used to produce beef. They are characterized by plump bodies, fast weight gain, high feed utilization, good meat production performance, and good meat taste. Beef cattle not only provide people with meat products, but also provide people with other side dishes. In the process of raising beef cattle, feed is indispensable. Only sufficient feed intake and sufficient digestion and absorption can promote the growth of beef cattle. Feed, as the most direct and important factor affecting the growth of beef cattle, affects the growth and production of beef cattle. Among them, silage feed can retain the nutrients in green feed to the maximum extent. The oxidation and decomposition of the material is relatively weak, and the nutrient loss is small. The silage material is fresh and juicy and has a long shelf life. It can adjust the imbalance of green feed supply. Therefore, a large amount of silage feed will be stored in large-scale feed farms for convenient use.

[0004] Traditional silage is mostly cut silage. Cut silage is coarse, which will increase the chewing amount of animals. The chewing muscles on both sides of the mouth chew vigorously, causing unnecessary energy loss. When the cut silage is put into the pit, bundled or bagged, hard and coarse feeds such as straw are not easy to compact. There is more air in it, which can easily lead to strong and active respiration of aerobic bacteria in the raw materials when the silage begins to ferment, causing a sharp rise in temperature. The high temperature almost kills all anaerobic fermentation bacteria, especially lactic acid bacteria. The silage produced in this way has a large loss of nutrients and low nutritional value. There is also a technology of kneading silage, but the silage is too fine and too short, the livestock does not chew enough, the saliva cannot be fully secreted, and it is unevenly mixed with the feed, which may cause the feed to pass quickly in the rumen. The fermentation time is too short, which will reduce the effective conversion rate of the feed, and even cause slow forestomach, rumen food accumulation or abomasum blockage. In addition, kneading silage may cause excessive water loss during kneading, mixing and filling and compacting, or cause part of the silage raw materials to undergo aerobic fermentation and begin to rot, producing a moldy layer. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the present invention is to solve the problem that the existing silage feed for beef cattle has an unreasonable structure, and the fermentation effect and the edible intake effect of beef cattle need to be improved.

[0007] (II) Technical solution

[0008] In order to solve the above technical problems, the present invention provides a beef cattle feed, comprising the following raw materials in parts by weight: 600-800 parts of plant feed, 0.75-5 parts of fermentation liquid and 6-10 parts of additives.

[0009] The plant feed can be used to make silage, which is prepared by mixing 20-50% by weight of kneaded material and 50-80% by weight of chopped material. The kneaded material is prepared by kneading the chopped material. The width of the kneaded material does not exceed 5 mm, and the length of the chopped material is 1-5 cm.

[0010] The fermentation liquid includes at least one of yeast, lactic acid bacteria and Bacillus subtilis.

[0011] The additives include trace elements and brown sugar.

[0013] Furthermore, the plant feed is prepared in one go using a grass-chopping and kneading mixer. When preparing the plant feed, the raw materials of the plant feed are fed into the grass-chopping and kneading mixer, which first chops the raw materials of the plant feed into chopped segments, then kneads one third of the chopped segments into kneaded segments, and finally mixes the un-kneaded segments and the kneaded segments and outputs them.

[0014] More specifically, the plant-based feed is prepared in one go using a grass-chopping and kneading mixer. The grass-chopping and kneading mixer for preparing the plant-based feed of the present invention in one go includes a frame, a shell, a conveying mechanism, a chopping mechanism, a dividing plate, a kneading mechanism and a mixing section. The shell is installed on the frame, a material channel is arranged in the middle of the shell, a conveying mechanism is installed at the front end of the material channel, a chopping mechanism is arranged downstream of the conveying mechanism, a dividing plate and a kneading mechanism are arranged downstream of the chopping mechanism, the dividing plate divides the material channel at the location of the kneading mechanism into a kneading channel and a chopping section channel, the cross-sectional ratio of the kneading channel and the chopping section channel is 1:2, a kneading mechanism is arranged in the kneading channel, a mixing section is arranged at the end of the material channel, the mixing section is a trumpet-shaped structure, and the mixing section guides the material coming out of the end of the material channel to the middle of the material channel for mixing and discharging.

[0015] More specifically, the grass chopping and kneading mixer for preparing the plant feed at one time also includes a transmission mechanism and a driving mechanism. The driving mechanism is connected to the transmission mechanism to drive its operation, and the conveying mechanism, chopping mechanism and kneading mechanism are respectively connected to the transmission mechanism to respectively convey, chop and knead the raw materials of the plant feed.

[0016] More specifically, the grass-chopping and kneading mixer for preparing the plant-based feed at one time has a kneading mechanism including a kneading shaft, which penetrates into the chopping section channel, and fan plates are respectively provided on the kneading shaft in the kneading channel and the chopping section channel.

[0017] Furthermore, the fermentation broth is prepared by mixing fermentation bacteria, cellulase, hemicellulase, amylase, lipase and xylanase as fermentation broth raw materials, and the fermentation bacteria include at least one of yeast, lactic acid bacteria and Bacillus subtilis.

[0018] Furthermore, the trace elements include yeast selenium with a purity of 0.4% and methionine zinc with a purity of 20%.

[0019] The present invention also provides a method for preparing beef cattle feed, which comprises the following steps:

[0020] S1. Raw material selection: select one or any combination of two or more of aquatic plants, alfalfa, ryegrass, awnless brome, corn stalks, sweet potato vines, pumpkin vines, clover and vegetable leaves as the raw materials of plant feed, and adjust the water content of the selected raw materials to between 60% and 70%;

[0021] S2, preparing the raw materials in step S1 into a mixed plant feed of kneaded silk material and chopped segment material at one time through a grass-cutting and kneading mixer;

[0022] S3. Mix the plant feed, fermentation liquid and additives in proportion and press them into bales or send them to silage pits. After fermentation at 25-45°C for 30-50 days, silage is obtained.

[0023] Furthermore, in the above-mentioned method for preparing beef cattle feed, the fermentation bacteria of the fermentation liquid are composed of 50% Bacillus licheniformis, 25% Lactobacillus plantarum, and 25% Candida albicans.

[0024] (III) Beneficial effects

[0025] The above technical solution of the present invention has the following advantages:

[0026] The silage of the present invention is a mixture of kneaded silk material and chopped segment material. The kneaded silk material and the chopped segment material are easy to compact during filling and fermentation, which reduces the air in the feed, reduces mildew and decay, and reduces premature loss of water, reduces the loss of nutrients in the produced silage, improves the quality of the silage, and ensures the nutritional value. In addition, the kneaded silk material and the chopped segment material are matched with coarse and fine materials. When the beef cattle ingest the feed, the amount of chewing is more reasonable, avoiding unnecessary energy loss caused by vigorous chewing; it also avoids the silage being too thin and too short, the livestock not chewing enough, the saliva cannot be fully secreted, and the feed is unevenly mixed, which may cause the feed to pass quickly in the rumen, and the fermentation time is too short, which will reduce the effective conversion rate of the feed, and even cause problems such as forestomach sluggishness, rumen food accumulation or abomasum blockage. The silage of the present invention is produced by a special grass-cutting, kneading and mixing machine, which simplifies the preparation process and improves the feed production efficiency. The kneading channel and the ratio of the chopping channel are set according to the required ratio of the kneading material and the chopping material, so that the kneading material and the chopping material can be matched quickly and the ratio is accurate. The processing steps of cutting, kneading and mixing the feed raw materials are completed in one go, which reduces manual operation and workload, and the production efficiency of the preparation method of beef cattle feed can also be guaranteed.

[0027] The silage prepared by the invention is of higher quality, more sour and fragrant, soft and juicy, has good palatability and is rich in nutrition, so that the growth nutrition of beef cattle is more balanced and the appetite of beef cattle is promoted, thereby achieving the purpose of promoting the feeding of beef cattle and improving the meat quality of beef cattle, thereby greatly improving the efficiency of beef cattle breeding.

[0028] The silage feed of the present invention has a reasonable structure and excellent fermentation effect, so only a small amount of fermentation liquid and additives are needed, which reduces the cost, and the preparation method is simple and has a higher market value.

[0029] In addition to the technical problems solved by the present invention, the technical features of the technical solutions constituted by the present invention, and the advantages brought about by the technical features of these technical solutions described above, other technical features of the present invention and the advantages brought about by these technical features will be further explained in conjunction with the accompanying drawings.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] Embodiment 1: A beef cattle feed, comprising the following raw materials in parts by weight: 600-800 parts of plant feed, 0.75-5 parts of fermentation liquid and 6-10 parts of additives. The plant feed can be used to make silage, that is, all plants that can be used to make silage can be used as raw materials for the plant feed of this embodiment. The plant feed is mixed with 20-50% kneaded silk material and 50-80% chopped segment material by mass percentage, that is, in the plant feed, the kneaded silk material accounts for 20-50%, and the chopped segment material accounts for 50-80%, such as the kneaded silk material accounts for 20%, 25%, 30%, 35%, 40%, 45%, 50%, and correspondingly, the chopped segment material accounts for 80%, 75%, 70%, 65%, 60%, 55%, 50%. The kneaded silk material is prepared by kneading the chopped segment material, so that the kneaded silk material is not too long, which is convenient for filling and compacting, and is convenient for filling the gaps between the chopped segment materials, reducing air retention, and improving the fermentation quality. The width of the kneaded material does not exceed 5mm, and the length of the chopped material is 1 to 5cm; the silage prepared by combining the kneaded material and the chopped material in this size range is of higher quality.

[0038] The fermentation liquid includes at least one of yeast, lactic acid bacteria and Bacillus subtilis; and the additives include trace elements and brown sugar.

[0039] Embodiment 2: This embodiment is based on the embodiment 1, and further optimizes the plant feed, specifically:

[0040] The mass ratio of kneaded silk material and chopped material in the plant feed is 1:2. The silage prepared by combining kneaded silk material and chopped material at this ratio is of higher quality. The amount of kneaded silk material is sufficient to fill the gap of chopped material, and the chewing amount is reasonably reduced for the intake of beef cattle, but it does not cause the silage to be too fine or too short, the livestock does not chew enough, the saliva cannot be fully secreted, and the silage is not mixed evenly with the feed, which may cause the feed to pass through the rumen quickly, the fermentation time is too short, and the effective conversion rate of the feed will be reduced, and even problems such as slow forestomach, rumen food accumulation or true stomach blockage will be caused. The raw materials of the plant feed include one or any combination of two or more of aquatic plants, alfalfa, ryegrass, awnless brome, corn stalks, sweet potato vines, pumpkin vines, clover and vegetable leaves, preferably corn stalks with green leaves and green stalks after de-earing, which has more sufficient and extensive raw materials and lower costs.

[0041] Embodiment 3: This embodiment provides a technical solution for quickly obtaining the required plant feed based on Embodiment 2, specifically:

[0042] The plant feed is prepared in one go by using a grass-chopping, kneading and mixing machine. When preparing the plant feed, the raw material of the plant feed is fed into the grass-chopping, kneading and mixing machine, which first chops the raw material of the plant feed into chopped segments, then kneads one third of the chopped segments into kneaded segments, and finally mixes the un-kneaded segments and the kneaded segments and outputs them. The plant feed with the required mass ratio of kneaded segments and chopped segments is quickly prepared.

[0043] like Figure 2-3As shown, the grass-cutting and shredding mixer for preparing the plant-based feed at one time comprises a frame 1, a shell 2, a conveying mechanism 3, a chopping mechanism 4, a dividing plate 5, a shredding mechanism 6 and a mixing part 7. The shell 2 is installed on the frame 1, and a material channel 8 is arranged in the middle of the shell 2. The material channel 8 passes through the shell 2 front and back. The conveying mechanism 3 is installed on the shell 2 at the front end of the material channel 8, and the chopping mechanism 4 is arranged on the shell 2 downstream of the conveying mechanism 3. The dividing plate 5 and the shredding mechanism 6 are arranged on the shell 2 downstream of the chopping mechanism 4. The dividing plate 5 divides the material channel 8 at the position of the shredding mechanism 6 into a shredding channel 9 and a chopping section channel 10. The cross-sectional ratio of the shredding channel 9 to the chopping section channel 10 is 1:2, and the shredding mechanism 6 is arranged in the shredding channel 9. A mixing section 7 is arranged at the end of the material channel 8, and the mixing section 7 is a trumpet-shaped structure, i.e., a closed structure. The mixing section 7 guides the material coming out of the end of the material channel 8 to the middle of the material channel 8 for mixing and discharging. That is, in the process of the material discharging from the material channel 8, the material is guided by the plates obliquely arranged on both sides of the mixing section 7, so that the kneaded material and the chopped material are gathered to the middle position of the material channel 8 (or the mixing section 7), and discharged from the mixing section 7 at the same time. In this process, the kneaded material and the chopped material are evenly mixed.

[0044] In this embodiment, the grass chopping and kneading mixer for preparing the plant feed at one time also includes a transmission mechanism 11 and a driving mechanism. The driving mechanism is a driving motor (not shown in the drawings). The transmission mechanism 11 is arranged on both sides of the rear half of the shell 2 and is provided with a protective shell. The driving mechanism is connected to the transmission mechanism 11 to drive it to operate. The conveying mechanism 3, the chopping mechanism 4 and the kneading mechanism 6 are respectively connected to the transmission mechanism 11 to respectively convey, chop and knead the raw materials of the plant feed.

[0045] It can be understood that the structural composition of the above-mentioned conveying mechanism 3, chopping mechanism 4, kneading mechanism 6, driving mechanism and transmission mechanism 11 can adopt the technology corresponding to the existing technology of the grass chopping and kneading machine, but it should be noted that the span setting of the kneading mechanism 6 is different from the existing technology. It is specially made for the beef cattle feed preparation of the present invention, and it is also an important invention technology point that is different from the existing technology. Its use in conjunction with the beef cattle feed preparation of the present invention can greatly improve the quality of silage (reducing artificial mixing, reducing the contact time between materials and the outside world, reducing the introduction of foreign matter, mixing more evenly, etc., thereby improving the quality of silage fermentation).

[0046] In the present embodiment, the grass-chopping and kneading mixer for preparing the plant-based feed at one time has a kneading mechanism 6 including a kneading shaft 12, which penetrates into the chopping section channel 10, that is, the kneading shaft 12 penetrates the dividing plate 5, and fan plates 13 are respectively provided on the kneading shaft 12 located in the kneading channel 9 and the chopping section channel 10. The rotation of the kneading shaft 12 drives the fan plate 13 to rotate, thereby facilitating the rapid discharge of materials in the kneading channel 9 and the chopping section channel 10.

[0047] Embodiment 4: This embodiment provides a preferred technical solution for fermentation broth based on Embodiment 3, specifically:

[0048] The fermentation broth is prepared by mixing fermentation bacteria, cellulase, hemicellulase, amylase, lipase and xylanase as fermentation broth raw materials, and the fermentation bacteria include at least one of yeast, lactic acid bacteria and Bacillus subtilis.

[0049] It is understandable that, according to the different raw materials of the selected plant feed and the different quantity of raw materials, the distribution ratio of each group of fermentation liquid raw materials can be appropriately adjusted to obtain the best gain effect. If the raw material of the selected plant feed is only corn straw, the fermentation strains: cellulase: hemicellulase: amylase: lipase: xylanase = 1.5: 2: 2: 2: 0.3: 0.3. Amylase, cellulase, and hemicellulase, as the main corn straw fermentation enzymes, can degrade polysaccharides such as cellulose, hemicellulose, and starch in the straw into monosaccharides, so that the utilization rate of straw feed and the production performance of animals can reach a considerable level.

[0050] Embodiment 5: This embodiment provides a preferred technical solution for trace elements based on Embodiment 4, specifically:

[0051] The trace elements include yeast selenium with a purity of 0.4% and methionine zinc with a purity of 20%. The usage of selenium and zinc elements is increased; the immunity and disease resistance of beef cattle are improved. In addition, brown sugar can be made into sugar water and sprayed evenly. The mass ratio of the trace elements in the additive to the brown sugar is 12:1.
