[0021] Prepare 490 kg corn, 80 kg wheat, 200 kg fresh wolfberry leaves, 40 kg soybean meal, 140 kg rapeseed meal, 30 kg cottonseed meal, 10 kg salt and 10 kg baking soda. Select ferrous sulfate, zinc sulfate, manganese sulfate, copper sulfate, sodium selenite, potassium iodide and other trace element additives, and accurately weigh them according to the proportion that can provide 5% of the total trace element amount.

[0022] Use a hammer mill to grind corn and wheat to a particle size of 2-3 mm. Dry fresh wolfberry leaves in a well-ventilated area for 3 days until the moisture content drops to about 12%, then grind them with a grinder to pass through a 50-mesh screen.

[0023] Initial mixing:

[0024] Put the crushed corn, wheat, wolfberry leaves, soybean meal, rapeseed meal and cottonseed meal into the horizontal ribbon mixer in turn. Set the mixer speed to 25 rpm and stir for 18 minutes to make the raw materials preliminarily mixed and evenly formed a mixture.

[0025] Trace element addition and premixing:

[0026] Use a high-precision electronic scale to accurately weigh salt, baking soda and various trace element additives in strict accordance with the recipe, ensuring that the error is controlled within ±0.1 gram.

[0027] Put the weighed trace element additives and 5 kg of corn flour into a small mixing container and stir manually for 8 minutes to evenly disperse the trace elements in the corn flour carrier.

[0028] Secondary mixing:

[0029] Add the pre-mixed trace element mixture to the preliminarily mixed raw materials, turn on the horizontal ribbon mixer again, adjust the speed to 35 rpm, and stir for 25 minutes to ensure that all ingredients are fully mixed.

[0030] Granulation:

[0031] A ring die pelletizer was selected and a ring die with an aperture of 5 mm was installed. Before the material entered the pelletizer, it was tempered by a steam conditioner with the steam pressure controlled at 0.25 MPa, so that the material temperature reached 80°C and the moisture content reached 17%.

[0032] The pelletized feed is cooled by a cooler to reduce the pellet temperature to room temperature and the moisture content to 13%. Then it is screened to remove unqualified large particles and fine powder to obtain finished pellet feed.

[0033] Experimental method: wolfberry leaves were added to the feed formula of the experimental group, and wolfberry leaves were not added to the feed formula of the control group. Two-month-old weaned lambs were fattened for 4 months with different formula feeds, and finally the weight gain and price were compared. The conclusion was drawn that the specific reference table of the formula is as follows:

[0036] Test results

[0037] 1. Comparison of weight gain effect: The experimental flock consisted of 2-month-old weaned lambs. After being divided into groups, the experimental group and the control group were fed with different formula feeds, weighed every 2 months, and fattened and marketed after 4 months. The results showed that the experimental group was basically above 35kg, 2.1kg higher than the control group on average, with significant weight gain effect.

[0038] 2. Comparison of feed prices: The formula feed of the experimental group is 3083 yuan / ton, and the formula feed of the control group is 3282 yuan / ton (calculated based on the market price in 2024). The experimental group is 199 yuan / ton less than the control group.

[0039] As a plant raw material with rich nutritional value and unique bioactive ingredients, wolfberry leaves are gradually entering the field of feed research and development. Wolfberry leaves are rich in vitamins, minerals and bioactive substances, such as flavonoids, polysaccharides, etc., and have antioxidant and immunomodulatory effects. Applying wolfberry leaves to lamb feed can not only provide additional nutritional support for lambs, but also help improve the immunity and health level of lambs.

[0040] The present invention aims to provide a lamb animal feed based on wolfberry leaves with comprehensive nutrition and good quality by accurately adjusting the proportions of raw materials such as corn, wheat, wolfberry leaves, soybean meal, rapeseed meal, cottonseed meal, etc., and reasonably supplementing trace elements such as Fe, Zn, Mn, Cu, Se, I, etc. At the same time, by optimizing the preparation process and improving the quality and stability of the feed, a better feed solution is provided for the lamb breeding industry, promoting the healthy development of the lamb breeding industry.

[0041] Combined with the results of this experiment, it is shown that wolfberry leaves, as a feed raw material, have high crude protein content and low fiber content, and are rich in nutrients and have high feeding value. When applied to feed in proportion, it has the advantages of fast weight gain and low price. In addition, the source of wolfberry leaves in Dulan County is abundant, which can not only solve the problem of forage shortage, but also increase the income of wolfberry growers. In addition, the price is low. Therefore, wolfberry leaves have broad application prospects in feed. In the future, the optimal addition amount and compatibility ratio of wolfberry leaves in different animal feeds can be further studied to provide a more scientific basis for the feed industry. At the same time, the composite application of wolfberry leaves and other feed raw materials can also be explored to improve the overall quality of feed and animal production performance.

[0042] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
