Problems solved by technology

In recent years, the excessive and irregular use of various drug additives and hormone growth substances has improved the economic benefits of pig production to a certain extent, but their residues in pork products have seriously threatened human health. Therefore, The healthy breeding of live pigs and the production of safe and high-quality pork products are the goals that the pig industry is striving to achieve at present

Embodiment Construction

[0019] A preparation method for a novel growth regulator for pigs, the steps are as follows:

[0020] (1) Preparation of cAMP

[0021] Using ATP as raw material, add Ba(OH) 2 , dissolved in distilled water, heated at 96°C for 40 minutes, then rapidly cooled to room temperature, centrifuged and the supernatant was taken as the cAMP sample;

[0022] (2) cAMP into salt

[0023] Add cAMP, 0.4mol / L triethylamine and anhydrous pyridine at a ratio of 1:7.2:5.3 (w / v / v), add 0.4mol / L triethylamine solution to the cAMP solution under freezing, and remove under reduced pressure at room temperature Continue to concentrate under reduced pressure to yellow oil at 55°C until the excess triethylamine has no odor, add anhydrous pyridine, shake and dehydrate, continue to remove pyridine under reduced pressure at 55°C, and then use anhydrous Repeated dehydration with pyridine once, vacuum-dried at 55°C to form a sponge, and cAMP triethylamine salt was obtained after drying;

[0024] (3) Acyl...

Abstract

The invention discloses a novel method for preparing a growth regulator used for pig. The method comprises the following steps: taking ATP as a raw material, adding Ba(OH)2 into the ATP to be dissolved in distilled water, distilling and heating the mixed solution at 96 DEG C for 40 minutes, and cooling and centrifugating the solution to obtain cAMP; preparing cAMP triethylamine salt by cAMP, 0.4mol/L triethylamine and absolute pyridine according to a proportion, and preparing DBC through acidylation and hydrolyzation; preparing DBC sodium salt by the DBC, sodium chloride, absolute ether and absolute ethanol according to a proportion; and mixing the DBC sodium salt and different assistant agents according to a proportion to prepare DBC growth regulator for feed addition and hypodermic injection. Animal experiments prove that the DBC growth regulator for the feed addition and the hypodermic injection can be effectively absorbed by animals with good stability, can remarkably improve the growth performance of pigs, can improve carcass quality without residue in animal body, and has higher safety compared with other chemical drug additives.

Description

1. Technical field [0001] The invention relates to a production method of a feed additive for livestock and poultry feeding, in particular to a preparation method of a growth regulator specially used for edible pigs. 2. Technical background [0002] At present, problems such as slow growth rate, excessive carcass backfat, and low lean meat rate are common in my country's pig production, especially in the production of local breeds, which seriously restrict the efficient development of my country's pig industry. Therefore, improving the growth rate of local breed pigs, reducing excessive fat deposition, and improving carcass quality are major problems to be solved urgently in pig production. In recent years, the excessive and irregular use of various drug additives and hormone growth substances has improved the economic benefits of pig production to a certain extent, but their residues in pork products have seriously threatened human health. Therefore, The healthy farming of...
