Compound feed for sows at pregnancy period and preparation method of compound feed

Abstract

The invention provides a compound feed for sows at a pregnancy period and a preparation method of the compound feed. Each 100 parts by weight of the compound feed comprises the following components inparts by weight: 16-65 parts of corn, 1.4-10.7 parts of soybean meal, 0-69 parts of barley, 0-37 parts of wheat bran, 0-37 parts of corn germ meal, 0-25.5 parts of corn bran, 1.35-1.55 parts of stonepowder, 0.8-1.1 parts of calcium hydrogen phosphate, 0.25-0.5 part of lysinesulphate, 0.05-0.15 part of baking soda, 0.1-0.6 part of table salt, 0.05-0.15 part of choline chloride and 0.3-0.8 part ofa premix. According to the compound feed for sows at the pregnancy period provided by the invention, the average number of piggies generated by the sows each time can be increased, the weight of thepiggies which are born and the weight of the piggies which are weaned are high, the survival rate of the piggies at the lactation period is high, the mammary development of the sows is good, the milkis sufficient, and the food consumption of the sows at the lactation period is high.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a compound feed for pregnant sows and a preparation method thereof. Background technique [0002] The feeding goals of sows are to increase birth weight, live piglets, and reduce production costs, and the fiber diets that have been reported have a positive effect, especially mentioning that they can improve the stereotyped behavior of sows during pregnancy and increase feed intake during lactation. Improve reproductive performance, etc. In sow breeding, the productivity of multiparous sows is higher than that of primiparous sows, so the management focus of the breeding farm should be to keep the multiparous sows in the herd as long as possible, so attention should be paid to growth, pregnancy The quality and quantity of daily fed feed in various stages such as lactation and lactation, that is, the level of energy, fiber, amino acid and protein, vitamins and minerals of feed....

AI Technical Summary

Problems solved by technology

The feeding of pregnant sows is different from ordinary sows. Pregnant sows have more nutritional needs. However, many domestic farmers and breeding enterprises use the same dietary formula for pregnant sows and ordinary sows, which may easily cause embryo mortality. High piglet size, low litter size, and low birth weight of piglets

At present, most sows are raised in stalls after pregnancy, and the sows lack exercise. At the same time, because the control of body condition needs to limit the feed intake of pregnant sows, the incidence of constipation in pregnant sows is over 60%.

On the one hand, constipation in pregnant sows will lead to insufficient stomach filling and weakened peristalsis, which will affect their feed intake during lactation, and the feed intake of sows during lactation directly affects lactation ability, determines the growth rate of piglets, and affects The economic benefits of breeding; on the other hand, if the harmful metabolites in the body cannot be discharged in time, it will cause harm to the sow, making the sow weak during childbirth, resulting in dystocia or prolonged labor, resulting in stillbirth and great damage to the sow's body , seriously affect reproductive performance
