The problem with early weaned piglets is that the passive immunity acquired by the piglets through mother's milk is interrupted, while the piglet's own immune system is not yet fully developed
[0005] (3) Decreased activity of digestive enzymes
[0006] (4) Other unfavorable external conditions: bad microclimate such as low temperature and humidity, unbalanced supplementary feeding, sudden change of diet, moldy and deteriorating feeding, lack of trace elements and vitamins in feed, and bacterial contamination of drinking water, will aggravate piglets' health problems. stress level

Embodiment 1
[0104] Weaning Protection Powder is composed of ingredients in the following weights:
[0111] Preparation method of additive for reducing stress of weaned piglets:
[0112] (1) Separation of oil cakes: The jujube seeds are separated from the oil cakes by mechanical pressing. Firstly, the jujube kernels are screened to remove impurities, and divided into two pieces, then check that the water content of the jujube kernels is 3-5% (W / W), and then directly enter the oil press for pressing, and then squeeze twice. Finally, filter to remove impurities, and put the separated jujube kernel cake and jujube kernel oil for later use.
[0113] (2) Grinding and sieving: the wild jujube kernel cake is crushed through a 150-mesh sieve with an ordinary low-temperature grinder; the remaining medicines are respectively crushed with a small low-temperature fixed hammer mill, and passed through a 120-mesh sieve for later use;
[0114] (3) Mixing amount: first add Suanzaoren and Poria cocos into the mixer and mix evenly, then add Anemarrhena, Chuanxiong, Shengdi, and Codonopsis int...

Abstract
The invention discloses an additive for reducing the weaning stress of a piglet, as well as a preparation method and application thereof. The additive is prepared from 15 to 25 grams of semen ziziphi spinosae (roasted), 6 to 9 grams of rhizoma anemarrhenae, 6 to 9 grams of poria cocos, 3 to 6 grams of rhizoma chuanxiong, 3 to 6 grams of dried rehmannia root, 6 to 12 grams of radix codonopsis, 6 to 9 grams of pericarpium citri reticulatae, 3 to 5 grams of radix platycodonis and 3 to 5 grams of radix et rhizoma glycyrrhizae. The invention further discloses the application of the additive for reducing the weaning stress of the piglet to reduction of the stress degree of a weaned piglet, regulation of the central nervous system and the endocrine of the piglet and improvement of the anti-stress capability of an organism. A result shows that weaning protection powder is added into feeds for the weaned piglet to achieve the effect of regulating the central nervous system and the endocrine of the piglet and simultaneously reduce occurrence of the weaning stress syndrome of the piglet.
Description
technical field [0001] The invention belongs to the field of animal nutrition technology research in animal husbandry, and relates to an additive for reducing weaning stress of piglets, a preparation method and application thereof. Background technique [0002] Early weaning stress of piglets can cause feed intake of weaned piglets to decrease by 15%-20%, growth stagnation, and prolonged feeding period. Early weaning stress syndrome in piglets is a major problem in pig production worldwide. The reasons include the following aspects. [0003] (1) Environment replacement. Early weaning stress mainly includes separation of mother and offspring, nutritional transition from breast milk to formula ration, and environmental change of piglets from farrowing pen to nursery pen. The results of its impact are clinically manifested as decreased feed intake and feed utilization efficiency in weaned piglets, dyspepsia, and the occurrence of diarrhea. [0004] (2) Immunosuppression. E...
