Piglet mixed feed additive for improving feed intake and application thereof

Abstract

The invention provides a piglet mixed feed additive for improving feed intake and an application thereof. The additive comprises the following components in parts by weight: 5-8 parts of Bacillus subtilis, 2-4 parts of Lactobacillus acidophilus, 30-40 parts of Acremonium acremonium culture, 5-8 parts of vitamin C, 2-4 parts of lysozyme, 4-6 parts of calcium formate, 2-4 parts of glucose oxidase, and 40-50 parts of milk powder. The piglet mixed feed additive is mainly directed to the post-weaning stress of piglets, and ensures the safety, effectiveness and stability of the feed additive compounding through clear formula ratio and the action mechanism of components, and significantly improves the feed intake of the nursery pigs, and the effect is stable and reliable; the piglet mixed feed additive has a strong target for the weaning stress period of the piglets, is stable and effective for the suckling piglets to pass from a lactation period to a feed feeding stage, significantly improves the growth performance of the nursery pigs, and improves the economic benefits of the farmers.

Description

technical field

[0001] The invention relates to the field of piglet feed additives, in particular to a piglet mixed feed additive for improving feed intake and its application. Background technique

[0002] During the weaning period of piglets, their physiology, immunity, etc. are not fully developed, and their digestive system is due to factors such as weaning stress, inadaptation to solid feed, and environmental changes, which lead to a significant decrease in feed intake of piglets. With the continuous improvement of the pig industry's requirements for production scale and production efficiency, how to solve the problem of feeding connection when piglets are weaned has become the key to breaking through the existing production efficiency.

[0003] At present, there are some related feed additives on the market to solve the problem of low feed intake of piglets. However, the formulations of these feed additives are relatively complex, the cost is high, and the mechanism o...

Examples

Embodiment 1

[0020] The mixed feed additive for piglets of this embodiment comprises the following components by weight: 5 parts of Bacillus subtilis, 2 parts of Lactobacillus acidophilus, 30 parts of Acremonium acremonium culture, 5 parts of vitamin C, lysozyme 2 parts, 4 parts of calcium formate, 2 parts of glucose oxidase, 50 parts of milk powder. The raw materials are uniformly mixed to obtain the mixed feed additive.

Embodiment 2

[0022] The piglet mixed feed additive of the present embodiment comprises the following components by weight components: 8 parts of Bacillus subtilis, 4 parts of Lactobacillus acidophilus, 40 parts of Acremonium acremonium culture, 8 parts of vitamin C, lysozyme 4 parts, 6 parts of calcium formate, 4 parts of glucose oxidase, 40 parts of milk powder. The raw materials are uniformly mixed to obtain the mixed feed additive.

Embodiment 3

[0023] Embodiment 3 feeding test

[0024] Test period: December 20, 2018 to January 17, 2019 (28 days).

[0025] Test location: pig farm in Xinji City, Hebei Province.

[0026] Selection of test objects: 160 healthy Dudu long-term three-way hybrid pigs aged 21-25 days and weighing 8.00kg±0.57kg were selected; they were randomly divided into two groups according to body weight and sex, one group was the test group, and the other was the test group. Control group, 80 piglets in each group, 8 replicates, 10 piglets in each replicate. Control group: diet is 60% corn + 40% suckling pig concentrate mixture of a certain company in Shijiazhuang; test group: diet is 59.5% corn + 40% suckling pig concentrate + 0.5% feed additive (Example 1 formula); except for the above-mentioned settings, feeding, management, and immunization were carried out according to the same daily procedures of the pig farm during the experiment.
