Micro-ecology preparation for pig feed, and preparation method thereof

Abstract

The invention discloses a micro-ecology preparation for pig feed, and a preparation method thereof, and belongs to the technical field of the micro-ecology preparation. The micro-ecology preparation comprises the following raw materials in parts by weight: 0.5-1 part of enterococcus faecalis, 0.2-1.2 parts of lactobacillus johnsonii, 0.5-1.0 part of bacillus subtilis, 0.2-0.5 part of bacillus licheniformis, 1-1.5 parts of clostridium butyricum, 0.5-1.5 parts of lactobacillus acidophilus and 1.5-2.0 parts of clostridium butyricum. The micro-ecology preparation disclosed by the invention can obviously lower the incidence rate of live pig intestinal diseases, improves a piglet growth rate, reduces feed consumption and drug expenditure, and greatly lowers culture cost.

Description

technical field [0001] The invention relates to the technical field of microbial preparations, in particular to a microecological preparation of pig feed and a preparation method thereof. Background technique [0002] With the expansion of the scale of pig raising in my country, the improvement of the degree of intensification, and the adoption of the latest breeding technology, the stress resistance of pigs has become worse and worse, and the requirements for environmental conditions have become higher and higher. In the feeding stage, the decline of pig stress resistance will lead to the slowdown or stagnation of the growth rate of growing pigs under various stress environments, and the reduction of feed remuneration; the resistance and immunity will decrease, and the susceptibility to some infectious diseases and parasitic diseases will increase, resulting in The prevalence of various diseases. In the slaughtering stage, the decline in stress resistance will lead to the ...

AI Technical Summary

Problems solved by technology

[0003] (1) Increased risks in pig farming, affecting pork supply

[0004] The slow growth or stagnation caused by the decline in the stress resistance of live pigs leads to a rapid increase in the cost of breeding such as feed, and the decline in immunity increases the risk of loss of epidemic diseases. operating costs

[0005] (2) Pork quality declines and safety issues occur frequently

PSE pork has a large weight loss and poor water retention, and its water loss rate is 4% to 5% higher than that of normal pork. The loss rate of this stress-induced pig during transportation is as high as 4.7% to 10.3% or more.

In addition, PSE pork is soft and inelastic, with serious loss of gravy, so it is not suitable for intensive processing, and the yield is low. The annual loss of meat quality caused by this is more than 1 billion yuan, which is currently the most risky part of pig farming.

At present, there is no economical and applicable method to solve the problem of PSE pork except for illegal methods such as lean meat essence and antibiotics. It can be seen that it is urgent to improve the stress resistance of pigs. Therefore, the improvement of pig stress resistance based on micro-ecological balance The market demand for technology and related products is immeasurable
