Embodiment 1

[0070] Embodiment 1—preparation of feed additive of the present invention

[0071] The feed additive comprises 80% by weight of Bacillus metabolic peptide, 50 mg / kg of organic selenium, 40 mg / kg of organic chromium, 1% by weight of organic zinc, 1% by weight of organic iron, 0.7% by weight of organic manganese, 0.5% by weight organic copper, 200mg / kg of vitamin E and 30mg / kg of vitamin C and the rest of soybean protein, the total of the above ingredients is 100% by weight.

[0072] The above weight percentages are all based on the total weight of the feed additive.

[0073] Among them, the Bacillus metabolic peptide is produced by the following method:

[0074] 1) Preparation of culture medium: 50kg of soybean meal with a crude protein content of 46%, 20kg of corn gluten meal with a crude protein content of 50%, 15kg of rapeseed meal with a crude protein content of 35%, 20kg of peanut meal with a crude protein content of 48%, 95kg of rice protein powder with a crude protein co...

Embodiment 2

[0084] Embodiment 2—commercial pig fattening

[0085] In this example, three yuan pigs with a body weight of about 80 kg (±5 kg) were fattened, and the feeding time was 40 days.

[0086] Grouping and management of commercial pigs

[0087] Choose 8 pens of healthy fat pigs, 25 pigs in each pen. Divide the 8 columns into 2 parts, 4 columns for the control group and 4 columns for the test group.

[0088] The pigs in the control group were fed with the control diet (feed for fattening pigs produced by Guangxi GL Company), and the pigs in the test group were fed with the feed additive prepared in Example 1 on the basis of the pig farm control diet. Soybean meal was obtained from the diet of the experimental group for feeding. Feed additives were added in an amount of about 3 kg per ton of the control diet.

[0089] The composition and nutritional standards of the control diet are shown in Table 1 below.

Embodiment 3

[0121] Embodiment 3—Preparation of control feed additive and commercial pig fattening

[0122] In this example, the same ingredients and steps as in Example 1 were used to prepare the control feed additive, wherein control 1 added insufficient amount of Bacillus metabolic peptide; control 2 did not add organic selenium; control 3 did not add organic chromium; control 4 did not add organic zinc ; The specific feed additive ingredients (vitamins E and C omitted) are listed in Table 6 below.

[0123] Table 6:

[0124]

[0125] According to the commercial pig fattening method in Example 2, the above five feed additives were applied to the fattening of ternary pigs weighing about 80 kg (±5 kg), and the feeding time was the same as in Example 2.

[0126] Compared with the ternary pigs fattened with the feed additive of the present invention in Example 1, the ternary pigs obtained by feeding the control 1 deteriorated in evaluation method 3) muscle drip loss evaluation and evalua...

Abstract

The invention belongs to the feed field and in particular relates to a feed additive, a feed comprising the feed additive as well as a method for improving pork meat quality by using the feed. Based on the total weight of the feed additive, the feed additive comprises the following components: 75wt%-90wt% of bacillus subtilis metabolism peptides, more than 0-100mg / kg organic selenium, more than 0-40mg / kg organic chromium, more than 0%-7wt% of organic copper, 0%-2.0wt% of organic iron, more than 0%-1.0wt% of organic manganese, 0.5wt%-1.5wt% of organic zinc and optional vitamin E and / or vitamin C. The feed additive has the advantages of being capable of improving the meat quality of pork to provide healthy pork which is juicy, fresh and crisp in mouthfeel, and rich in selenium and zinc.

Description

technical field [0001] The invention belongs to the field of feed, and in particular relates to a feed additive, a feed containing the feed additive, and a method for improving pork meat quality by using the feed. Background technique [0002] Over the past half a century, the swine industry around the world has developed rapidly, and both hog production and pork production have increased significantly. However, while the quantity increased, serious problems such as the decline of pork quality, the addition of clenbuterol, water-injected meat, and dead pork appeared successively, which brought direct and indirect harm to people's health and the natural environment. Pork quality issues have attracted widespread attention from producers, consumers and nutritionists: from the 1980s when people called for eating "lean pork", to the 1990s when people called for eating "safe meat", and since entering the 21st century, people have been It is even more urgent to eat "safe meat" and...
