Problems solved by technology

[0004] In the current feed formulation, the main problem is that Nα + 、K + The ion content is low, Cl - The ion content is high, which makes it difficult for the electrolyte balance value to exceed 150mEq / kg
On the other hand, the effect of electrolyte balance agents on the market is not obvious, and the function is single. The commonly used electrolytes mainly include sodium bicarbonate and potassium chloride. However, for young animals, due to insufficient gastric acid secretion, low-acid diets are The problem that must be considered, adding sodium bicarbonate will increase the acidity of the diet system, but the content of chloride ions in potassium chloride is too high, and the adjustment effect is not obvious
However, there is no literature report on the application of disodium α-ketoglutarate in pig feed

Embodiment 1

[0012] Disodium α-ketoglutarate is added to drinking water in an amount of 0.1-0.5% and mixed well; then fed to suckling piglets, weaned piglets, growing pigs and breeding pigs together with feed; it can effectively relieve pig stress , reducing the diarrhea rate of piglets after weaning, improving their production performance, and also significantly improving the meat quality.

Embodiment 2

[0014] The disodium alpha-ketoglutarate is compounded with carriers such as diatomite or stone powder in a ratio of 1:1 to 4:1 to make a compound: powder premix or granular premix. The obtained compound is added to the feed to feed suckling piglets, weaned piglets, growing pigs and breeding pigs, and the amount of the compound is 0.1-1% of the total weight of the feed; it can effectively slow down suckling piglets, weaned piglets and growing pigs. And the stress of breeding pigs, reduce the diarrhea rate of piglets after weaning, improve their production performance, and also have a significant improvement in the improvement of meat quality.

Embodiment 3

[0016] Compound disodium α-ketoglutarate and stearic acid and other carriers in a ratio of 1:1 to 4:1, and through a freeze-spray drying process, a compound is prepared: microcapsule particle premix; The compound is added to the feed for feeding suckling piglets, weaned piglets, growing pigs and breeding pigs. The amount of the compound added is 0.1-0.8% of the total weight of the feed; it can effectively relieve the stress of suckling piglets, weaned piglets, growing pigs and breeding pigs. , reducing the diarrhea rate of piglets after weaning, improving their production performance, and also significantly improving the meat quality.

Abstract

The invention discloses a preparation method for alpha-oxoglutarate disodium and application of alpha-oxoglutarate disodium in a pig feed. A test shows that when alpha-oxoglutarate disodium is applied to the pig feed, the pig stress condition can be obviously alleviated, the productivity performance of pigs is obviously improved, and the meat quality is also obviously improved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to the application of disodium α-ketoglutarate in preparing pig feed. Background technique [0002] Electrolyte balance in organisms plays a very important role in the life activities and production performance of animals. In addition to maintaining osmotic pressure in the body, regulating acid-base balance, controlling water metabolism and constituting the necessary components of certain enzymes, Appropriate electrolyte content can protect the suitable metabolic environment of nutrients and prevent important nutrients (such as lysine, etc.) from acting as alkaline ions in the body to reduce their utilization efficiency. [0003] A large number of studies have shown that the most important factor in determining the acid-base balance in animals is Nα + 、K + , Cl - Three kinds of ions are basically provided by the diet, and the electrolyte balance value of the diet can be ex...
