Description

Technical Field

[0001] This invention patent relates to the field of feed technology, and more specifically, to a feed for fattening cattle. Background Technology

[0002] During the fattening period of beef cattle, their weight, muscle, and fat tissues undergo further growth and development, thereby improving meat quality and yield. The feeding goal during the fattening period is to fully utilize the cattle's growth potential, rapidly fattening them for slaughter. Improving feeding practices and providing sufficient nutrition during this period allows the cattle to achieve compensatory growth. In recent years, with the continuous development of animal husbandry, beef cattle farming has become increasingly focused on scientific and rigorous fattening methods. Compared to traditional methods, large-scale intensive beef cattle farming places greater emphasis on the use and selection of feed for fattening cattle.

[0003] Currently, most commercially available cattle feeds increase their protein content by adding substances such as soybean meal, rapeseed meal, cottonseed meal, and corn germ meal. While the high-protein substances added to existing cattle feeds provide protein intake, they can also increase the burden on the cattle's digestive system, leading to insufficient nutrient absorption.

[0004] Therefore, this invention, through research and development, provides a feed for fattening cattle to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of this invention is to solve the existing technical problems mentioned in the background section and to provide a feed for fattening cattle.

[0006] The above-mentioned objective of the present invention is achieved as follows:

[0007] A feed for fattening cattle comprises the following components, by weight percentage:

[0008] 20-60 parts fermentation mixture, 10-16 parts modified coconut fiber, 0.5-1.5 parts additives, and 5-10 parts additives;

[0009] The fermentation mixture is made from soybean meal, corn, rice bran, sweet elephant grass, hops, Aspergillus oryzae culture, yeast, Bacillus subtilis, and Bacillus amyloliquefaciens; the mass ratio of soybean meal, corn, rice bran, sweet elephant grass, and hops is 2-4:1-3:3-5:2-4:0.4-0.9.

[0025] The additive is monk fruit residue;

[0026] The additive is a mixture of Codonopsis pilosula and Atractylodes lancea.

[0027] Furthermore, the Codonopsis pilosula and Atractylodes lancea are in powder form and are in a 1:1 ratio.

[0028] Furthermore, the preparation method of the fermentation mixture includes the following steps:

[0029] S1. Mix soybean meal, corn, rice bran, sweet elephant grass, hops and Aspergillus oryzae culture according to the mass ratio, then add 1 volume of deionized water and grind into a mixed slurry;

[0038] 3) The coconut fiber treated material is steam-exploded for 1-4 minutes under a pressure of 2-3 MPa and a temperature of 121℃, and then dried to obtain modified coconut fiber.

[0039] The difficulty and significance of the technical problem solved by this invention lie in:

[0040] Currently, in the breeding of fattening cattle, due to the large feed intake of beef cattle, large-scale farming requires artificial feeding with commercial feed. While commercially available cattle feed can promote protein intake to some extent, it can also increase the burden on the cattle's digestive system, leading to insufficient nutrient absorption. Therefore, based on research into the characteristics of fattening cattle, the inventors of this application have overcome the fixed mindset of traditional feed structures and designed a new formula for fattening cattle feed. This new formula aims to improve the apparent digestibility, growth performance, serum biochemical indicators, and antioxidant indicators of fattening cattle. The solution of this invention is of great significance for improving the quality of fattening cattle.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The feed of the present invention is composed of soybean meal, corn, rice bran, sweet elephant grass and hops, which are then fermented by yeast, Bacillus subtilis and Bacillus amyloliquefaciens. This effectively ensures the protein content while enriching and increasing the beneficial components and nutrients, thus effectively promoting the weight gain of beef cattle during the fattening period.

[0043] 2. The feed of the present invention contains modified coconut fiber, which can effectively absorb excess nutrients from other food substances and reduce the excessive burden on the stomach of cattle caused by excessive nutrients after ingesting food or feed.

[0044] 3. The feed of the present invention contains monk fruit residue, which can improve the apparent digestibility, growth performance, serum biochemical indicators and antioxidant indicators of fattening cattle, thus effectively improving the quality of fattening cattle.

[0070] The efficacy verification test of adding monk fruit residue as an additive in the feed according to the embodiments of the present invention is as follows:

[0071] 1. Materials and Methods

[0072] 1.1 Experimental Materials

[0073] The fattening cattle were provided by a farm in Guilin City, Guangxi Province. The monk fruit residue was purchased from Guilin Jifusi Monk Fruit Biotechnology Co., Ltd., and the ELISA kit for measuring antioxidant capacity was purchased from Shanghai Lianmai Biotechnology Co., Ltd.

[0074] 1.2 Experimental Design

[0075] Sixty healthy Simmental crossbred cattle, weighing approximately 282.0 kg and of similar age, were randomly divided into four groups with 15 replicates per group and one cow per replicate. A 60-day feeding trial was conducted, including a 7-day pre-trial period and a 60-day formal trial period. In the fattening cattle experimental groups, different proportions of Luo Han Guo (monk fruit residue) were used to replace the basal diet in experimental groups 1, 2, and 3, respectively. Groups 1, 2, and 3 received 4%, 8%, and 12% Luo Han Guo residue as basal diet replacements, respectively. The control group was fed only the basal diet (see Table 1). The basal diet was formulated by the large-scale farm according to the nutritional standards of the "Beef Cattle Feeding Standard" (NY / T815-2004) (see Table 2).

[0079]

[0080]

[0081] Note: 1. Nutritional composition is based on actual measured values; 2. Premixed feed was purchased from COFCO (Beijing) Feed Technology Co., Ltd.

[0082] 1.3 Feeding and Management

[0083] After the experimental cattle were put into the pen, they were tethered and fed, with free access to water and feed. They were fed twice a day, from 6:00 to 6:30 and from 17:00 to 17:30. Regular immunization and disinfection were carried out in strict accordance with the cattle farm's rules and regulations. Disease incidence was observed and recorded.

[0084] 1.4. Measurement and Methods of Relevant Indicators

[0085] (1) Measurement of apparent digestibility of nutrients

[0086] Three days before the end of the experiment, one cow was randomly selected from each group and each replicate daily to determine apparent digestibility. Feces were collected manually via rectal extraction, with approximately 200g of fresh feces collected from each cow. The samples were mixed thoroughly, dried in a drying oven, and then pulverized into powder using a fine sieve. The nutrient content of the feed samples was determined according to the "Feed Analysis and Feed Quality Testing Technology," including dry matter, crude protein, crude fat, crude fiber, calcium, and phosphorus, and their apparent digestibility was calculated.

[0087] Apparent nutrient digestibility = (content of a nutrient ingested - content of a nutrient in feces) / content of a nutrient ingested × 100%.

[0088] (2) Growth performance determination

[0089] After the pre-trial period, the trial period began. On the morning of the first day of the trial and the day after the trial ended, the total daily feed intake, remaining feed intake, and total weight gain of the fattening cattle were recorded. The average daily feed intake (ADFI), average daily weight gain (ADG), and feed conversion ratio (F / G) were also calculated.

[0090] ADFI = (Total feed intake - Remaining feed intake) / Total feeding days;

[0091] ADG = Total weight gain / Total feeding days;

[0092] F / G = Total feed consumed / Total weight gain

[0093] (3) Measurement of serum biochemical and antioxidant indicators

[0094] After the formal experiment, approximately 10 mL of fasting jugular vein blood was collected from one cow in each experimental group. After standing for 1 hour, the blood was centrifuged at 3000 rpm for 15 minutes. The supernatant serum was collected, and the levels of total protein, albumin, globulin, total cholesterol, high-density lipoprotein, low-density lipoprotein, glucose, triglycerides, and blood urea nitrogen were measured using a Mindray-420 fully automated biochemical analyzer. ELISA kits were used to detect antioxidant capacity-related indicators in the serum: catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), and malondialdehyde (MDA).

[0095] 1.5 Data Statistics and Analysis

[0096] The raw data were first statistically analyzed using an Excel spreadsheet, then analyzed using SPSS 22.0 software for variance analysis, and finally analyzed using Duncan's algorithm. ’ Multiple comparison analysis was performed using the s-method, and the results are expressed as mean ± standard deviation.

There was no significant difference in the content of malondialdehyde (MDA) in serum between the experimental groups and the control group.

[0115] Table 6. Effects of adding Luo Han Guo pomace to the diet on the antioxidant capacity of fattening cattle.

[0116]

[0117] 3. Mechanism Analysis

[0118] 3.1 Effect of adding Luo Han Cao (Siraitia grosvenorii) residue to the basal diet on the apparent nutrient digestibility of fattening cattle

[0119] The apparent digestibility of nutrients in beef cattle is closely related not only to the type of feed but also to the rumen environment, reflecting the body's ability to digest and utilize the diet. Monk fruit residue contains no anti-nutritional or toxic components and can be used as a high-quality roughage for ruminants. Adding a roughage degrading agent to fresh monk fruit residue and allowing it to ferment can produce a high-quality biological feed for ruminants such as beef cattle, with an optimal concentration of around 8%, which can significantly improve animal digestibility and absorption. The above research results indicate that adding 8% monk fruit residue to the basal diet significantly increases the content of crude protein, crude fat, and calcium, while the crude fiber and phosphorus content of the control group is significantly higher than that of the experimental group. This may be because the quality of processed monk fruit residue is improved, making it more palatable for fattening cattle, thereby increasing the apparent digestibility of nutrients.

[0120] 3.2 Effects of adding Luo Han Cao (Siraitia grosvenorii) residue to the basal diet on the growth performance of fattening cattle

[0121] Monk fruit residue contains a large amount of digestible crude fiber and sugars, providing animals with a certain amount of energy and replacing part of the basal diet. The results of this study indicate that adding 8% monk fruit residue to the basal diet significantly improves the total weight gain, average daily feed intake, and average daily weight gain in fattening cattle, while reducing the feed conversion ratio. This is because the polysaccharide component in monk fruit residue—monokara—can affect rumen microorganisms and enzyme activity in ruminants, improving feed utilization and thus enhancing the growth performance of fattening cattle.

[0122] 3.3 Effects of adding Luo Han Cao (Smilax china) residue to the basal diet on serum biochemical indicators and antioxidant capacity of fattening cattle

[0123] Serum biochemical indicators reflect the physiological functions and metabolic status of animals. Total protein, albumin, and globulin levels are important indicators of normal protein metabolism in animals. In this study, adding 8% *Luo Han Guo* (monk fruit residue) to the basal diet of fattening cattle significantly increased the levels of total protein, globulin, total cholesterol, high-density lipoprotein, glucose, and triglycerides in their serum, while significantly decreasing urea nitrogen levels. Adding traditional Chinese medicine additives to beef cattle diets can increase the levels of total protein, globulin, and glucose in the serum of beef cattle, thereby improving the body's protein metabolism capacity. The results indicate that *Luo Han Guo* residue can improve serum biochemical indicators in fattening cattle.

[0124] Serum antioxidant indicators can reflect the health status of animals. In this study, the serum catalase (CAT), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and total antioxidant capacity (T-AOC) activities were significantly increased after adding 8% monk fruit residue to the basal diet of fattening cattle. The reason for this may be that the flavonoid polysaccharides in monk fruit residue can inhibit peroxidation and the production of reactive oxygen species.

[0125] In summary, the above embodiments of the present invention demonstrate that adding Luo Han Guo (Siraitia grosvenorii) residue to the basal diet of fattening cattle can improve the apparent digestibility, growth performance, serum biochemical indicators, and antioxidant indicators of fattening cattle, with the best effect achieved at an addition amount of 8%. Furthermore, the components of the present invention also include Codonopsis pilosula and Atractylodes lancea. Atractylodes lancea is pungent and bitter in taste, warm in nature, and enters the spleen, stomach, and liver meridians; it dries dampness, strengthens the spleen, dispels wind and cold, and improves eyesight. Codonopsis pilosula is sweet in taste and neutral in nature; it tonifies the middle energizer, replenishes qi, quenches thirst, strengthens the spleen and lungs, nourishes blood, and promotes body fluid production. Adding these two Chinese medicinal herbs can maintain the health of the spleen and stomach of fattening beef cattle, ensuring their overall health.

[0126] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
