Problems solved by technology

The amount of the piglet feed additive added is 5-10% of the total mass of the feed. It has been clinically proven that the feed added with the piglet feed additive can promote the growth of piglets and increase the weight of the piglets when they are weaned. However, the use of the piglet feed additive, Increased piglet production costs

Embodiment 1

[0019] The production method of the suckling piglet of the present embodiment, comprises the following steps:

[0020] 1) Prepare licorice extract

[0021] Take 1kg of licorice, use a slicer to cut the raw material into 2-3mm slices, add 1kg of water to soak for 4 hours, microwave in batches, 500g each time, then add 3 times more water, first heat with strong fire, and then use slow fire after boiling Heat for 2h, pour out the fried liquid.

[0022] Then decoct the dregs twice, combine the decocted liquid, filter out the dregs, heat and concentrate the filtrate in a vacuum, and then concentrate in a water bath at 60°C until the crude drug content is 1g·mL -1 , and then centrifuged at a speed of 3000 rpm for 20 min and then suction filtered to obtain a filtrate.

[0023] Slowly add an aqueous ethanol solution with an ethanol volume fraction of 95% to an ethanol volume fraction of 60% in the above-mentioned filtrate, then refrigerate overnight, then carry out suction filtratio...

Embodiment 2

[0030] The difference between the production method of suckling piglets in this embodiment and the production method of suckling piglets in Example 1 is that the quality of the licorice extract added in every 100 kg of basal diet is 2.5 kg.

Embodiment 3

[0032] The difference between the production method of suckling piglets in this embodiment and the production method of suckling piglets in Example 1 is that the quality of the licorice extract added in every 100 kg of basal diet is 0.5 kg.

Abstract

The invention relates to a production method for suckling piglets, belonging to the technical field of vertebrate breeding. The production method of the present invention comprises the following steps: adding additives mainly composed of licorice polysaccharide and glycyrrhizic acid to the basal ration of suckling piglets for free feeding of suckling piglets; the added amount of licorice polysaccharide is 0.275-2.95 %; the mass ratio of glycyrrhizic polysaccharide and glycyrrhizic acid in the additive is 5~16:1. In the production method of the present invention, additives whose main components are glycyrrhizic polysaccharide and glycyrrhizic acid are added to the basal ration of suckling piglets, so that the suckling piglets can eat freely, which can increase the feed intake of piglets, and improve the blood sugar level and serum antioxidant capacity , so as to increase the weight of suckling piglets when they are transferred to the group, improve the production performance of piglets as a whole, and at the same time improve the disease resistance of suckling piglets, reduce the mortality rate of piglets, and enhance the body's antioxidant capacity.

Description

technical field [0001] The invention relates to a production method for suckling piglets, belonging to the technical field of vertebrate breeding. Background technique [0002] The growth performance of piglets during lactation affects the final growth performance, slaughter performance and meat quality of commercial pigs, and is a critical stage of pig production. The birth weight of suckling piglets is relatively light, even less than 1% of adult pigs, but the growth rate is fast and the metabolism is strong. At the age of 30 days, the weight of piglets can reach 6-7 times the weight at birth. After 2 months, The weight of the piglets will reach 10 to 13 times that at birth. However, the digestive organs of suckling piglets are not perfect, and their digestion ability is poor; their body temperature regulation center is not fully developed, and their body stores less energy; they lack antibodies in their bodies, and their resistance to diseases is also poor. If the pigle...
