Description

Technical Field

[0001] The invention belongs to the technical field of feed preparation, and specifically relates to a piglet starter feed and a preparation method thereof. Background Art

[0002] Piglet starter feed, also known as creep feed or newborn piglet feed, refers to a feed specially designed for newborn piglets to help them transition from breast milk to solid food. This feed is usually introduced shortly after the piglets are born, and is generally tried to be supplied when the piglets are about one week old until around weaning. The purpose of the design of the starter feed is to adapt to the digestive system of piglets, ensure that the nutrition is sufficient and easy to digest and absorb, and help piglets gradually adapt to the process of eating solid food. Piglet starter feed has the characteristics of easy digestion and absorption, comprehensive nutrition, good palatability, and disease prevention; starter feed usually uses easily digestible raw materials, such as wheat flour, corn flour, etc., and undergoes certain processing, such as puffing, spray drying, etc., to make the feed easier for piglets to digest; some feeds contain protein, energy, vitamins, minerals and other essential nutrients required for piglet growth to support the healthy growth of piglets; starter feeds usually add some flavors or other ingredients that attract piglets' appetite to increase piglets' feed intake; some starter feeds may also contain probiotics or antibiotics to help piglets establish a healthy intestinal microbial community and prevent diseases such as diarrhea. However, there is still much room for improvement in the current piglet starter feed in terms of digestion and absorption, nutrition and disease prevention. Summary of the invention

[0020] Comparative Example 1 The difference between this comparative example and Example 1 is that in step S1, the compound vitamins only contain 30000 IU vitamin A, 2000 IU vitamin D, 80 mg vitamin E, and 4 mg vitamin K, and the other steps are the same.

[0021] Comparative Example 2 The difference between this comparative example and Example 1 is that in step S1, the multivitamin only contains 30000 IU vitamin A, 2000 IU vitamin D, 35 mg vitamin B2, 25 mg vitamin B6 and 70 mg vitamin C, and the other steps are the same.

[0022] Comparative Example 3 The difference between this comparative example and Example 1 is that in step S1, only 40 mg of niacin, 10 mg of copper, 35 mg of iron, 30 mg of zinc and 20 mg of manganese are taken in the composite trace elements, and the other steps are the same.

[0023] Comparative Example 4 The difference between this comparative example and Example 1 is that the composite trace elements in step S1 are only 40 mg niacin, 10 mg copper, 35 mg iron, 1 mg iodine, 0.1 mg selenium and 0.5 mg chromium, and the other steps are the same.

[0024] Comparative Example 5 The difference between this comparative example and Example 1 is that in step S1, only 1 mg of lysine and 2 mg of methionine are taken in the composite amino acid, and the other steps are the same.

[0025] Comparative Example 6 The difference between this comparative example and Example 1 is that yeast and bran powder carrier enzyme preparation are not added in step S1, and the other steps are the same.

[0026] Performance Test: Determination of starter feed intake: During the test period, the feed intake and the remaining feed amount were recorded every day; the difference between the feed intake and the remaining feed amount was the feed intake. Growth performance: The weight of each piglet was accurately measured before the start of the test period, on the 31st, 38th, 46th and 53rd days of the test period. The measurement was carried out before morning feeding to see the increase.

[0027] The results are shown in the table below: Table 1 Performance test results

[0028] It can be seen from the above performance test results that the starter feed increase and average daily weight gain of Examples 1-3 are relatively good. In particular, the comprehensive performance of Example 3 is the most outstanding. Compared with the Examples, the comparative examples are significantly worse than the Examples in the corresponding performance tests due to the different compositions of composite vitamins, composite trace elements, and composite amino acids. The above experimental results further prove the importance of the technical solution defined in the present invention for its technical effect.

[0029] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
