Feed for sows in suckling period

Abstract

The present invention discloses a feed for sows in a suckling period. The feed comprises the following raw material components in parts by weight: 10-30 parts of bananas, 4-16 parts of valeriana officinalis tea, 5-11 parts of calcium hydrogen phosphate, 6-9 parts of calcium carbonate, 5-8 parts of methionine, 3-6 parts of aureomycin, 12-48 parts of fish meal, 14-54 parts of corn and 3-12 parts of protease. The valeriana officinalis tea can soothe disturbed mood of the sows, reduce stress behavior, can relatively better prevent produced glucocorticoids induced by the stress from penetrating placentas into fetus bodies, thereby prevents the lack of immune globulin G (IgG) in piglets, also reduces the risk of the sows in pressing the piglets dead, and increases milk of the sows.

Description

technical field [0001] The invention belongs to the technical field of poultry feed, in particular to a feed for lactating sows. Background technique [0002] my country is the largest pig-raising country in the world and the second largest feed production country in the world. Among them, pig feed accounts for more than 40% of the total, and the feed industry occupies an important position in the national economy. In the process of raising pigs, the number of weaned piglets provided by each sow per year is the most important economic indicator of a pig farm, that is, the number of weaned piglets = the number of litters per year * the number of live piglets per litter * the survival rate of the farrowing room, but , the number of live piglets in the actual pig farm is about 10, the survival rate in the farrowing room is about 80%, and the number of weaned piglets is only about 8.2. The perinatal period refers to the period from before delivery to the second day after delive...

In the process of raising pigs, the number of weaned piglets provided by each sow per year is the most important economic indicator of a pig farm, that is, the number of weaned piglets = the number of litters per year * the number of live piglets per litter * the survival rate of the farrowing room, but , the number of live piglets in the actual pig farm is about 10, the survival rate in the farrowing room is about 80%, and the number of weaned piglets is only about 8.2. The perinatal period refers to the period from before delivery to the second day after delivery), in a state of physiological stress, and the glucocorticoids induced by stress penetrate the placenta and enter the fetus, which will lead to immune immunity in piglets. Deficiency of globulin G (IgG), therefore, ultimately leads to lower survival rates in the farrowing house. On the other hand, if the sow is constantly stressed, the sow will have a reduced appetite, reduce milk production, and also squeeze the piglets, Reduced survival rate of piglets
