Nutritional supplement for sows

Abstract

The invention discloses a nutritional supplement for sows. The nutritional supplement comprises, by weight, 5-20 parts of calcium gluconate, 5-20 parts of calcium lactate, 0.01-1 part of zinc lactate, 5-20 parts of glucose, 5-20 parts of maltose, 5-20 parts of saccharose, 0.2-2 parts of feed acidifiers and 0.03-1.6 parts of scent attractants. The nutritional supplement does not occupy the abdominal volume and convenient to feed, the sows like to eat the nutritional supplement, and the functions of supplementing nutrients, improving the stamina, improving the appetite, helping digestion, preventing constipation, promoting normal peristalsis and constriction of uteri and birth canals, helping eutocia, shortening the birth process and reducing the probability of birth canal injuries are achieved by applying the nutritional supplement before delivery; and by applying the nutritional supplement after delivery, the sows can start eating early, the stamina is good, the milk amount is large, recovery is fast, growing and weight increment of all piglets are facilitated, and arrival of the normal oestrus of the next farrow is facilitated.

Description

technical field [0001] The invention relates to a comprehensive nutritional supplement for sows with prenatal constipation, poor feed intake, labor fatigue, long labor process, postpartum non-eating, and weak milk. Background technique [0002] Modern industrialized pig farming has extremely high production efficiency. Sows have many offspring (12-16 per litter), high body consumption, frequent parity, short recovery intervals, and great physiological pressure on sows. [0003] Before the sow gives birth, more than a dozen fetuses in the abdomen have grown to a large size, occupying the space in the abdominal cavity, oppressing the digestive tract, and reducing the feed intake of the sow. But at this time, the fetus in the abdomen needs a lot of nutrition, which creates a contradiction, resulting in a group of prenatal and postpartum symptoms: [0004] ① This contradiction caused the minerals, especially calcium, of sows to make ends meet, the smooth muscle peristalsis of t...

Problems solved by technology

[0006] ③Long labor process and dystocia also aggravate the injury of the birth canal of sows

[0008] The existing pig raising technology has not been able to find the root cause of the above problems, so it is difficult to solve the problem completely:

[0009] 1) In order to solve the problem of decreased feed intake of sows before delivery, "prenatal food intake restriction" is generally adopted, and some limit feeding for several days, making sows more nutritionally deficient, and more likely to cause weak delivery, dystocia, and less postpartum milk

[0010] 2) To solve the constipation of sows: the current methods include giving the sows some grass, increasing the water supply, exercising the sows, or injecting drugs to stimulate them. Insufficient gastrointestinal volume is only effective for some pigs, and in many areas there is no fresh grass in winter; to let sows exercise, many pig farms do not have space and manpower, and it takes extra time and energy for breeders; increasing water supply is wishful thinking. Sows do not necessarily drink it, and it has little effect on constipated pigs; drug injection costs are high, operation is troublesome, and the effect is not obvious

[0011] 3) The problem of too long delivery process of sows has attracted more and more attention, but there is no good solution

The current method of pig farms is just to wait, and some will fight and force to exercise
