Problems solved by technology

However, adding antibiotics in large doses for a long time will cause the micro-ecology in the animal's digestive tract to lose its balance, causing infection, and a large amount of antibiotics will cause the generation of drug-resistant pathogenic strains, which may make the antibiotics lose their effectiveness when disease treatment is needed, and cause serious damage to the disease. Difficult to treat and even a threat to animal and human health

Embodiment 1

[0020] Embodiment 1: the preparation of feed additive

[0021] Weigh according to the following weight proportions: 50 parts of D-aspartic acid, 5 parts of Lactobacillus paracasei, 10 parts of Lactobacillus delbrueckii subsp. bulgaricus, 10 parts of Bifidobacterium adolescentis, and 25 parts of carrier soybean meal powder.

Embodiment 2

[0023] Example 2: Effect of Feed Additives on Growth Performance of Weaned Piglets

[0024] Select 28 healthy three-way hybrid (Du×Long×Da) weaned piglets with an average body weight of 9.43±0.35kg, and randomly divide them into 4 groups according to the principle of half male and half female and similar body weight, with 7 replicates in each group. Repeat for 1 pig. Wherein the control group is fed with conventional basal rations, and the other three groups of treatment groups are fed with basal rations mixed with the feed additives prepared in Example 1 in different proportions. By mixing feed additives, the basal rations of the three groups of treatment groups The contained D-aspartic acid (D-Asp) was 50 mg / kg, 500 mg / kg and 5000 mg / kg, respectively. The test period is 28 days.

[0025] The composition and nutrient level of the basal diet were formulated with reference to the nutritional requirements of 10-30kg weaned piglets in the US NRC (2012). The dietary compositi...

Abstract

The invention discloses a feed additive for improving the growth performance of weaned piglets. The feed additive is prepared from D-aspartic acid, lactobacillus paracasei, lactobacillus delbrueckii subspecies bulgaricus, bifidobacterium adolescentis and soybean meal serving as a carrier. Preferably, the feed additive is prepared from the following components in parts by weight: 50 parts of the D-aspartic acid, 5 parts of the lactobacillus paracasei, 10 parts of the lactobacillus delbrueckii subspecies bulgaricus, 10 parts of the bifidobacterium adolescentis and 25 parts of the carrier soybeanmeal powder. The feed additive does not contain any antibiotic component, and has the advantages of no toxicity, no drug residue, no drug resistance, no pollution and the like. Besides, the feed additive contains three probiotics, and due to the unique physiological activity and biological functions of the three probiotics, the feed additive has the effects of improving immunity, maintaining normal flora balance of gastrointestinal tract, helping to generate adhesion resistance and the like.

Description

technical field [0001] The application belongs to the technical field of animal nutrition, and in particular relates to a feed additive for improving the growth performance of weaned piglets and its application. Background technique [0002] After weaning, the immune system of the piglets is immature and their ability to resist diseases is poor, coupled with the interruption of the supply of maternal antibodies and the occurrence of strong stress after weaning, the immunity of the piglets after weaning is reduced, the feed intake is reduced, and the daily gain is reduced. , and even growth stagnation, diarrhea and dehydration, and even cause post-weaning multisystem failure syndrome in severe cases, which seriously affects the production efficiency of the pig industry. [0003] Usually, antibiotics etc. are added as growth promoters during the weaning stage to solve this problem. However, adding antibiotics in large doses for a long time will cause the micro-ecology in the ...
