Embodiment 1
[0022] The feed additive for improving pig reproductive performance in Example 1 of the present invention includes the following raw materials in parts by weight:
[0023] 10 parts of mugwort leaves, 10 parts of Moringa leaves, 8 parts of Eucommia, 10 parts of Luo Han Guo, 6 parts of pine needle powder, 6 parts of yeast powder and 4 parts of β-mannanase.
[0024] Preparation:
[0025] S1: Take Artemisia argyi leaves, Moringa leaves, Eucommia ulmoides and Luo Han Guo respectively, wash away impurities, dry and crush, pass through an 80-mesh sieve, combine the coarse powder, add water 10 times the total weight of the coarse powder, and then add 1.0% of the total coarse powder The cellulase was extracted at 45°C for 3 hours, then refluxed at 90°C for 4 hours, filtered, the filtrate was concentrated under reduced pressure to an extract with a relative density of 0.90 at 60°C, and the extract was dried and crushed to obtain a coarse powder for later use ;

Embodiment 2
[0028] The feed additive for improving pig reproductive performance in Example 2 of the present invention includes the following raw materials in parts by weight:
[0029] 6 parts of mugwort leaves, 8 parts of Moringa leaves, 6 parts of Eucommia ulmoides, 8 parts of Luo Han Guo, 4 parts of pine needle powder, 4 parts of yeast powder and 2 parts of β-mannanase.
[0030] The preparation method is the same as in Example 1.
Embodiment 3
[0032] The feed additive for improving pig reproductive performance in Example 3 of the present invention includes the following raw materials in parts by weight:
[0033] 12 parts of mugwort leaves, 12 parts of Moringa leaves, 10 parts of Eucommia ulmoides, 12 parts of Luo Han Guo, 8 parts of pine needle powder, 8 parts of yeast powder and 6 parts of β-mannanase.
[0034] The preparation method is the same as in Example 1.

Abstract
The invention relates to the field of livestock farming, in particular to a feed additive for improving swine reproductive performance and a preparation method thereof.The feed additive comprises the following materials for preparation: leaves of Artemisia Argyi, leaves of Moringa oleifera, bark of Eucommia, fruit of Momordica grosvenori, pine needle meal, yeast powder, beta-mannosidase and a milk flavoring agent.The additive of the invention has the effects of preventing miscarriage, fighting bacteria and diminishing inflammation, relaxing the bowels, inducing diuresis, expelling parasite and improving sleep and also improves appetite of a pig, increases feeding quantity of the pig and promotes growth and development by improving the tasting and smelling sensations of the pig for feed.The additive of the invention can significantly increase litter size of a sow, reduce miscarriage and reduce fetal mortality, can increase milk volume of a sow and daily weight gain of a piglet, has significant effect of improving swine reproductive performance, and is simple to prepare, high in safety, free of irritation and worthy of popularization.
Description
technical field [0001] The invention relates to the field of livestock breeding, in particular to a feed additive for improving pig reproductive performance and a preparation method thereof. Background technique [0002] my country is a big pork producing country in the world, and its annual pork production accounts for more than half of the world's total pork production. The level of pig production has progressed rapidly, but there is still a gap with advanced countries. The breeding performance of imported breeding pigs is low, and the annual parity of sows is less than 2. At present, each sow in my country produces an average of 13-15 piglets, the level of the United States is 22-25, and that of Europe is 25-30, which is quite different from foreign countries, and the problem of pig reproduction is prominent. [0003] There are infectious factors and non-infectious factors that cause the decline of pig reproductive ability. Among them, infectious factors include virus in...
