Feed additive for sows at lactation period

Abstract

The invention mainly relates to the technical field of raising of pigs, and discloses a feed additive for sows at a lactation period. The feed additive is prepared from the following raw materials in parts by weight: 26-28 parts of spirulina, 17-19 parts of pumpkin seed oil, 11-13 parts of soybean protein, 5-7 parts of calcium gluconate, 2.3-2.5 parts of zinc sulfate, 1.2-1.4 parts of sodium selenite, 1.1-1.3 parts of lycopene and 13-15 parts of lactic acid bacteria. The feed additive is balanced in nutrients, rich in fragrance, good in palatability and easy to absorb, the quality of milk of the sows can be improved, the survival rate of piggies can reach 100%, the number of born fetuses of the sows can be increased to 12-13, the replacement frequency of the sows is obviously reduced, and the economic returns are increased by 10.4%; and the calcium gluconate, the zinc sulfate and the sodium selenite are added, so that the losses of mineral elements, caused by long-term lactation of the sows, can be complemented, the disease resistance of the sows is strengthened, nutrient components of the milk can be balanced, the absorption of the piggies can be promoted, the immunity of the piggies can be enhanced, and the survival rate of the piggies can be increased.

Description

technical field [0001] The invention mainly relates to the technical field of pig raising, in particular to a feed additive for lactating sows. Background technique [0002] In the process of raising pigs, the quality of the sow directly determines the growth of the piglets, and the milk quality of the lactating sow directly determines the survival rate of the piglets. In the traditional breeding process, the first lactation volume of the lactating sow Insufficient, after maintaining 5-6 births, the lactation volume began to decline again. At present, most sows will be eliminated after 7-8 births in industrialized pig farming, and the sows will be replaced frequently, which will significantly increase the cost of raising pigs. Therefore, There is a need for a feed additive that improves the milk quality of sows and reduces the replacement times of sows. Contents of the invention [0003] In order to remedy the defects of the prior art, the purpose of the present invention...
