Technical Field
[0001] The invention relates to the technical field of feed, and in particular to a koi color-enhancing high-fat compound feed and a preparation method thereof. Background Art
[0002] Koi Color Yang High-Fat Formula Feed is a feed specifically designed for koi, designed to promote vibrant coloration and healthy growth. Key features of this Koi Color Yang High-Fat Formula Feed include: 1. High fat content, optimized for fat ratio, achieving energy efficiency by replacing protein with fat, reducing feed costs; 2. Enhanced color development. Natural pigments such as spirulina and astaxanthin are added to thicken the red disc and enhance the red color; 3. Functional additives are added to help regulate fat deposition in koi, preventing problems such as increased abdominal fat and abnormal body shape caused by high-fat diets.
[0003] Patent application CN119563802A discloses a high-fat formula feed for koi carp coloring and its preparation method. The use of crude protein, such as fish meal, soybean meal, rapeseed meal, and peanut meal, can reduce production costs; while pigments, such as capsanthin, green algae, and lutein, can enhance koi coloring. However, crude protein and pigments are susceptible to environmental factors such as light, heat, and pH, which can reduce the activity and efficacy of the prepared formula feed.

[0009] S2. Add the compound feed into deionized water and mix thoroughly to obtain raw materials; add the raw materials into an extruder and granulate to obtain granular feed; dry the granular feed to prepare the Koi Color Yang high-fat compound feed.
[0010] Furthermore, in step S1, the method for preparing the oil swelling agent comprises the following steps:
[0011] A1, peony seed oil and olive oil are mixed to obtain a mixed oil; fish meal, soybean meal, shrimp meal and peanut meal are mixed to obtain a mixed core material powder;
[0012] A2. Select a Wurster device with a side-spray fluidized bed; add the mixed oil to the fluidized bed, which generates air to suspend the mixed oil; spray the mixed core material powder through a spray tube and be coated with the mixed oil to prepare a oil expander.
[0013] Furthermore, in step A1, the mass ratio of peony seed oil to olive oil is 1:1, and the mass ratio of fish meal, soybean meal, shrimp meal and peanut meal is 1:1:1-2:1; in step A2, the mass ratio of mixed oil and mixed core material powder is 2-3:1.
[0014] Furthermore, the preparation method of the pigment complex comprises the following steps:
[0015] B1, spirulina, astaxanthin, green algae and lutein are blended to obtain a pigment mixture; the pigment mixture is added to deionized water and stirred until the pigment mixture is completely dissolved to obtain a core material; the core material, chloroform and cyclohexane are blended to form an organic matter;
[0016] B2. Add an emulsifier to the organic matter, stir at high speed, then add a cyanoacrylate monomer, react at 25-35° C., and then filter to remove chloroform and cyclohexane to obtain microcapsules; wash the microcapsules with deionized water to prepare a pigment complex.
[0017] Furthermore, in step B1, the mass ratio of spirulina, astaxanthin, green algae and lutein is 1:2-3:1:2-3, the mass ratio of the pigment mixture and deionized water is 1:30-50; and the mass ratio of the core material, chloroform and cyclohexane is 1:1:3-4.
[0018] Furthermore, in step B2, the ratio of the organic matter, emulsifier and cyanoacrylate monomer is 10 mL: 0.1-0.2 g: 5-10 mL; the speed of high-speed stirring is 1000-2000 r / min, and the duration of high-speed stirring is 5-10 min.

The mixed oil is coated with the above-mentioned crude protein composition to avoid oxidative inactivation of the crude protein powder composition during granulation and drying and solidification; in addition, the oil wall material can improve its own taste. The feed formula of the present invention contains various nutrients, which has the effects of enhancing color, avoiding fat deposition of koi, and balancing and enriching various nutrients.

[0061] Comparative Example 1
[0062] The difference between this comparative example and Example 9 is that step A2 is omitted, the mixed oil and the mixed core material powder are blended in a mass ratio of 2:1 to obtain a compound; and the compound of equal mass is used to replace the oil expander.
[0063] Comparative Example 2
[0064] The difference between this comparative example and Example 9 is that the preparation method of the pigment complex is different, and specifically comprises the following steps:
[0065] Spirulina, astaxanthin, green algae and lutein are blended in a mass ratio of 1:2:1:2 to obtain a pigment complex.
[0066] Performance test: One-year-old red and white koi with an initial body weight of 30±0.5g were selected as experimental subjects. 10 red and white koi were selected for each group. Examples 7-9, Comparative Examples 1-3 and 7 blank control groups were set up in sequence. The blank control group was fed with commercially available koi basic feed (purchased from Zhongshan Wanao Pet Products Co., Ltd., Crazy Water Grass Koi Fish Feed). In a 500L breeding water bucket at a water temperature of 25°C, continuous oxygen was added for 24 hours, and 1 / 3 of the tap water was replaced every two days after being exposed to direct sunlight for more than 24 hours of continuous oxygen. The red and white koi of Examples 7-9, Comparative Examples 1-3 and the blank control group were fed at 500mg / kg; they were fed three times a day for one month.
[0067] 1. Use a colorimeter to record the colorimetric values of the skin of all grouped fish, including the values of skin brightness L*, head redness a*, and head yellowness b*.
[0068] 2. Record the weight gain of the koi in Examples 7-9 and Comparative Examples 1-3. See Table 1 below for the specific test results.
[0069] Table 1. Performance test data of samples
[0070]
[0071] Data Analysis: A comparative analysis of the data in Table 1 above shows that feeding the high-fat formula feeds prepared in Examples 7-9 to enhance the color of both red and white koi carp enhances their body color. This is demonstrated by significant increases in skin brightness, head redness, and head yellowness after feeding the formula feeds prepared in Examples 7-9. However, in Comparative Example 2, the pigment mixture was not coated with an organic monomer, which resulted in partial inactivation of the pigment mixture, resulting in decreased skin brightness, head redness, and head yellowness values for the koi.
[0072] The high-fat, color-enhancing formula feeds for koi prepared in Examples 7-9 of the present invention all exhibited significant weight-gain efficiency. However, in Comparative Example 1, the mixed core material powder was not coated with a mixed oil, but was simply blended. This resulted in partial inactivation of the crude protein during pelleting and feeding, and the resulting formula feed compromised the weight-gain effect on koi.
