Description

Technical Field

[0001] The present application relates to the field of feed, and in particular to an ecologically nutritious high-quality protein feed and a preparation method thereof. Background Art

[0002] Pigs are one of the important sources of meat. They are tender, delicious and nutritious, and are loved by consumers. The market demand for pork is large, and pig farming is an important source of economic income for farmers. Therefore, pig breeding is of great significance to the development of agricultural breeding and food production.

[0003] In the traditional agricultural breeding process, the feed ingredients of pigs are relatively simple, often only including fine bran or other grains. The growth of pigs is slow, and the problem of protein deficiency is particularly obvious when pigs grow. Later, scholars and farmers have made efforts to solve the problem of protein deficiency in pig growth, but the results are not significant. With the continuous development of agricultural breeding, protein feed with soybean cake as the main raw material has gradually attracted everyone's attention. Protein feed with soybean cake as the main raw material has the following advantages: First, soybean cake is an important source of plant protein, with high protein content and good quality. The content of lysine, methionine, tryptophan and cystine is higher than that of soybeans, which can make up for the lack of animal protein and meet the growth needs of pigs. Secondly, soybean cake has high energy and good palatability. Bean cake contains high fat and carbohydrates, which can provide sufficient energy. At the same time, its natural fragrance and high palatability can promote the appetite of pigs. In addition, soybean cake is easy to obtain and relatively low in price, which can reduce the cost of feeding.

[0004] However, the above-mentioned protein feed protein with soybean cake as the main raw material still has the following problems:

[0005] First, although the protein content in soybean cake is high, its amino acid ratio is unbalanced, such as the low methionine content. Therefore, when soybean cake is used as feed, it is usually necessary to feed it with some animal protein feed to achieve protein complementation. However, there are many types of animal protein feed, and there is no standardization on which type to choose and how much to add.

[0006] Secondly, the nutritional components of different types of soybean cakes are not exactly the same. The choice of soybean cake needs to be determined based on the growth stage and nutritional needs of the pigs. This problem is not easy to overcome in the actual breeding process.

[0007] In summary, although protein feed with soybean cake as the main raw material has various advantages, its defects such as variety and difficulty in selection and imperfect nutritional components still need to be made up. Based on this, the present application provides an ecological nutrition high-quality protein feed and a preparation method thereof. Summary of the invention

[0008] In order to improve the defects of protein feed in the related art which uses soybean cake as the main raw material, such as the variety of types that are difficult to select, and the uneven nutritional components, the present application provides an ecologically nutritious high-quality protein feed and a preparation method thereof.

[0100] Detection test:

[0101] Twelve healthy Taihu pigs with complete vaccines were selected. Before testing, the pig house was cleaned and disinfected, and the temperature and harmful gas (ammonia) concentration in the pig house were monitored. After reaching the standard, the 12 pigs were weighed and divided into four groups for feeding, wherein the first group was fed with the feed prepared in Example 1, the second group was fed with the feed prepared in Example 2, the third group was fed with the feed prepared in Example 3, and the fourth group was fed with the feed of the comparative example. The feeding period was 7 days, and each pig was weighed every day to calculate its average daily weight gain and 7-day weight gain.

[0102] The test results are shown in Table 1.

[0103] Table 1

[0104] sample Average original body weight / kg Body weight after 7 days / kg Average daily weight gain / kg Group 1 65.34 70.54 0.743 Group 2 65.47 71.54 0.867 Group 3 65.28 65.84 0.651 Group 4 65.51 69.12 0.515

[0105] Combining Table 1 and the embodiments and comparative examples, it can be seen that the weight gain of the first, second and third groups is good. Seven days later, a random pig of the second group was slaughtered, and 500g of the longest muscle between the fifth rib and the last rib was taken and sent for inspection according to the experimental requirements. The meat color, marbling, muscle pH, shear force, water holding capacity, cooked meat rate, intramuscular fat, inosinic acid, cholesterol, and amino acids were tested. The test results were not significantly different from the known test data of Taihu pigs, which shows that the weight gain effect of the data of the second group is better than that of the protein feed in the prior art under the premise of ensuring the health of the pig body and good meat quality.

[0106] Result analysis:

[0107] The feed of the present application adopts a variety of different raw material combinations, including fermented soybean cake, fermented grass feed, rapeseed meal, corn flour, oats, sweet potato flour, soybean oil, fish meal, etc., which can provide more comprehensive and rich nutrients. At the same time, compared with the protein feed in the prior art, although the present application also uses soybean cake, the proportion of soybean cake in the feed is greatly reduced. Fermented soybean cake, fermented grass feed and corn flour are used as the main ingredients of the feed, and the component contains fish meal, which can supplement plant protein and animal protein and is nutritionally balanced.

[0108] The corn flour raw material of the three main components of the present application is easy to obtain, and the fermented soybean cake and the fermented grass feed are fermented to degrade the anti-nutritional factors in the two, thereby increasing the absorbability and nutritional utilization rate of the feed.

[0109] The feed of the present application contains allicin, vitamins, sweeteners, spices and probiotics: allicin contains natural antibacterial and antioxidant activity, which helps to enhance the immunity and digestive function of pigs. Vitamins are essential substances for the normal physiological functions of pigs and can promote the growth and healthy development of pigs. Sweeteners and spices can improve the appetite of feed and increase the food intake of pigs. Probiotics can maintain the intestinal health of pigs and promote nutrient absorption.

[0110] In summary, the protein feed provided by the present application provides comprehensive nutrition, including protein, carbohydrates, fat, vitamins and microorganisms. This balanced diet contributes to the overall growth and development of Taihu pigs and improves their average daily weight gain rate.

[0111] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
