Problems solved by technology

Every year, as many as 200,000 tons of discarded tea leaves are pruned from tea trees. Most of these tea leaves are directly left in the fields as fertilizers, resulting in a huge waste of resources. This part of resources should be rationally used in the breeding industry to improve breeding performance and production. Green and healthy edible products have very broad prospects

Effect test

Embodiment 1

[0024] A total of 240 healthy growing pigs with a body weight of 60±3.0kg were randomly divided into 4 treatment groups, each treatment group had 6 replicates, and each replicate had 10 pigs. The composition of the experimental diet was prepared according to the nutritional requirements of pigs in the US NRC (2012). The specific ingredients of the diet are shown in Table 1.

[0025] Wherein, treatment 1 is the control group, treatment 2, treatment 3 and treatment 4 are the test groups, and different weight percentages of tea powder a or tea powder b are added to the diets of the test groups, and the test period is 60 days. During the experiment, the feeding management procedures and immunization procedures were carried out according to the conventional commercial pig feeding management manual.

[0026] In the diet, the tea powder a made by conventional crushing method is as follows:

[0027] (1) Place the fresh tea leaves in the sun to dry naturally or at 65°C until the water...

Embodiment 2

[0055] In this embodiment, the composition of the diet and feed used in the test is shown in Table 6, wherein the composition of the premix in the diet and feed is shown in Table 7, treatment 1a is the control group, treatment 2a, treatment 3a and treatment 4a are all experimental Different weight percentages of tea powder a or tea powder b were added to the diet of the test group.

[0056] The preparation method of the fattening pig diet is as follows:

[0057] Weigh corn, 46.5% soybean meal, premix, wheat bran and tea powder according to the weight percentage of the composition feed, add them into the mixer, and stir for 4 minutes; then add salt, lysine, Methionine, threonine, soybean oil, calcium hydrogen phosphate and stone powder, continue to stir for 5 minutes; then, put them in a dryer and dry them at 70°C.

[0058] The test period is 60 days, and the pig breeds, test methods and test detection items for the breeding test are the same as in Example 1.

Embodiment 3

[0065] In this embodiment, the composition of the diet and feed used in the test is shown in Table 8, wherein the composition of the premix in the diet and feed is shown in Table 9, treatment 1b is the control group, treatment 2b, treatment 3b and treatment 4b are all experimental Different weight percentages of tea powder a or tea powder b were added to the diet of the test group.

[0066] The preparation method of the fattening pig diet is as follows:

[0067] Weigh corn, 46.5% soybean meal, premix, wheat bran and tea powder according to the weight percentage of the composition feed, add them to the mixer, and stir for 3 minutes; then add salt, lysine, Methionine, threonine, soybean oil, calcium hydrogen phosphate and stone powder, continue to stir for 4 minutes; then, put them in a dryer and dry them at 65°C.

[0068] The test period is 60 days, and the pig breeds, test methods and test detection items for the breeding test are the same as in Example 1.

Abstract

The invention relates to a fattening pig feed for improving the pork quality. The feed comprises the following components in percentage by weight: 72%-75% of corns, 10%-13% of 46.5% bean pulp, 1%-6% of wheat bran, 3%-7% of tea leaf powder, 1.2%-1.5% of bean oil, 1%-1.4% of stone powder, 1.2%-1.4% of calcium hydrogen phosphate, 0.3%-0.6% of salt, 3%-4% of premix, 0.2%-0.3% of lysine, 0.1%-0.2% of methionine and 0.1%-0.2% of threonine. Compared with the prior art, the feed is prepared by drying branches and leaves cut from tea trees, performing conventional or superfine grinding to prepare the tea leaf powder, and adding the tea leaf powder into the fattening pig feed instead of the bran according to a certain ratio; the prepared feed contains not only special nutritional ingredients such as protein, fat, carbohydrate and the like in the tea leaves but also medicinal ingredients such as caffeine, tea polyphenol, lipopolysaccharide, aromatic compounds and the like, and can effectively promote the growth performance of a fattening pig, enhance the anti-stress capability and improve the quality, flavor and mouth feel of pork.

Description

technical field [0001] The invention relates to a feed for pigs, in particular to a feed for fattening pigs for improving meat quality. Background technique [0002] With the development of science and technology, the breeds of pigs have been continuously improved, and the high-yield and excellent genes of various breeds of pigs have been hybridized and integrated. Now the production potential of pigs is increasing. In order to give full play to the production potential of fine breed pigs, animal nutrition research has also been obtained. A great breakthrough has been made, and the research has reached the molecular level. The result of the synchronization of pig breed improvement and animal nutrition is that the production performance of fine breed pigs has been greatly improved compared with before, such as the growth cycle of commercial pigs has been continuously shortened from the original one year to the current five to five years. After six months, the feeding efficie...
