Low-toxicity and high-fiber feed for pregnant sows

Abstract

The invention relates to low-toxicity feed capable of preventing constipation and improving the number of healthy piglets by 0.5 for pregnant sows. A preparation method of the feed breaks and changesa traditional corn and bean meal type feed formula into a barley and bean meal type daily ration, substitutes barley for corn completely and uses corn germ meal cooperatively. The low-toxicity feed for the pregnant sows has the beneficial effects that the corn germ meal is added to the feed for the pregnant sows to increase the content of fibers, the feed can effectively reduce toxin in a productwhen fed to pigs on the basis of preparation into the feed for the pregnant sows, the sows cannot suffer from constipation after eating the feed, the number of healthy piglets is improved by 0.5, theculture benefit of a livestock farm is improved, and the feed has broad market prospects.

Description

technical field [0001] The invention relates to a low-toxin, high-fiber feed for pregnant sows. Background technique [0002] A variety of reasons will lead to constipation in sows after pregnancy, which will further affect the growth and development of fetuses in the mother. The main factors affecting constipation in sows are as follows: First, the sows restrict the movement of sows after they are bred. And the feed intake is low, which will inevitably lead to the weakening of the digestion and absorption function of the sow, resulting in the decrease of the intestinal function of the sow, and the dryness of the intestinal content, thus causing constipation; The pressure on the rectal wall is increased, rectal peristalsis is reduced, feces stay in the rectum for too long, and water is overabsorbed, causing constipation in sows; third, physiological and psychological stress of sows before delivery, leading to enhanced gastrointestinal peristalsis , the water in the large in...

[0002] A variety of reasons will lead to constipation in sows after pregnancy, which will further affect the growth and development of fetuses in the mother. The main factors affecting constipation in sows are as follows: First, the sows restrict the movement of sows after they are bred. And the feed intake is low, which will inevitably lead to the weakening of the digestion and absorption function of the sow, resulting in the decrease of the intestinal function of the sow, and the dryness of the intestinal content, thus causing constipation; The pressure on the rectal wall is increased, rectal peristalsis is reduced, feces stay in the rectum for too long, and water is overabsorbed, causing constipation in sows; third, physiological and psychological stress of sows before delivery, leading to enhanced gastrointestinal peristalsis , the water in the large intestine is absorbed into the blood too much, causing constipation in sows. When feeding the high-protein diet in the late pregnancy, the ability of the large intestine to absorb and secrete liquid is relatively changed, making the large intestine full and prone to constipation; fifth, some sows suffering from some heat-source diseases can also cause constipation , Infections such as swine fever (more common in mild types), toxoplasmosis and blue ear disease will cause constipation in sows

Constipation in sows leads to increased embryonic mortality in pregnant sows, fewer litters and more weak litters; prolonged labor and suffocation of piglets due to hypoxia, which increases the mortality rate of sows; sows have fever and do not eat, It is easy to cause postpartum agalactia syndrome; increase the difficulty of piglet breeding; postpartum sows cannot go into estrus normally, or even do not go into estrus; increase feed costs, reduce production efficiency and other problems
