Problems solved by technology

[0003] Constipation in sows during pregnancy is a common and frequent problem. At present, most of the feeds fed to pregnant sows are extremely low in crude fiber content, which can easily cause constipation in sows to varying degrees.
Common sow feeds in the market only add inorganic minerals, and the absorption rate is generally only 2% to 10%. Most of the inorganic minerals are excreted from the body, which increases the pressure on the environment; Necessary trace elements that can lead to serious consequences
For example: manganese deficiency will lead to slow fetal bone development, severe cases will cause fetal death or premature death; zinc deficiency will lead to reduced litter size and birth weight; selenium deficiency will cause premature birth, abortion and stillbirth in pregnant sows

Embodiment

[0024] A concentrated feed for improving the farrowing performance of pregnant sows, in parts by weight, comprising the following components (see the table below):

[0025]

[0026]

[0027] The multidimensional used in Examples 1-4, per kilogram of multidimensional includes: vitamin A is 22750-30333KIU, vitamin D3 is 4725-6300KIU, vitamin B2≥13.5g, vitamin B6≥2.1g, vitamin E≥189.1g, vitamin K3 ≥6.8g, vitamin B12≥0.05g, niacin≥68.6g, pantothenic acid≥34.9g, folic acid≥1.0g, biotin≥1.0g.

[0028] The polymineral that uses among the embodiment 1-4, comprises in per kilogram polymineral: copper 18.4-22.9g, iron 88.5-110.6g, zinc 28.5-35.6g, manganese 71.8-89.8g, iodine 0.26-0.33g, selenium 0.2 -0.25g.

[0029] The stone powder used in Examples 1-4 is feed grade stone powder, the main component is calcium carbonate, the calcium content is above 38%, the magnesium content is below 0.5%, and the content of other heavy metals is within the national standard.

[0030] Dibasic ...

Embodiment 4

[0034] The polymine described in Example 4 contains per kilogram: copper: 22.9g, iron: 110.6g, zinc: 35.6g, manganese: 89.8g, iodine: 0.33g, selenium: 0.25g, and the balance is carrier.

[0035] The preparation method of the concentrated feed that improves the farrowing performance of pregnant sows that embodiment 1-4 provides is:

[0036] (1) Accurately weigh each component;

[0037] (2) Because there are many raw materials, the proportion and weight of different raw materials are different. In order to ensure the uniformity of mixing, the feed mixer is divided into a small material feeding port and a large material feeding port; the small material feeding port and the large material feeding port are equipped with a screen Net, the feeding order of each component weighed by step (1) is as follows:

[0038] Large material feeding port: carrier, puffed soybean, fish meal, soybean oil, secondary powder, salt, stone powder, calcium hydrogen phosphate;

[0039] Small material fe...

Abstract

The invention discloses concentrated feed for improving the farrowing performance of pregnant sows and a preparation method of the concentrated feed. The concentrated feed mainly comprises extruded soybeans, fish meal, wheat shorts, soybean oil, calcium hydrogen phosphate, limestone powder, salt, lysine, methionine, magnesium sulfate, a phytase 5000, a compound enzyme preparation, a mycotoxin absorbent, a flavoring agent, multiple vitamins, multiple minerals, a carrier and other microelements. The concentrated feed for the pregnant sows can meet the nutrient requirement of the sows and improve the farrowing performance of the pregnant sows and has the significant economic benefit.

Description

technical field [0001] The invention relates to the field of livestock feed, and relates to a concentrated feed for improving the farrowing performance of pregnant sows and a preparation method thereof. Background technique [0002] The farrowing performance of sows is an important production index of a large-scale pig farm, and it is also an important index to measure the production management level of a large-scale pig farm. First-class scale pig farms have an average litter size of more than 10 live litters; the average litter size is 9-10. The nutritional status of the sow significantly affects the physiological status of the sow. The physiological processes of fertilization, embryo implantation, and embryonic development of the sow are inseparable from a good nutritional status; feed nutrition for pregnant sows is to ensure the fecundity of sows, improve Basis for sow litter size. [0003] Constipation in sows during pregnancy is a common and frequent problem. At pres...
