Problems solved by technology

Although the feed additive formula disclosed in this patent contains a variety of amino acids, vitamins and trace elements, and adding it to the feed can improve the taste of the feed, but the formula uses Chinese herbal medicine raw materials such as Radix Astragali, Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizoma Atractylodes Rhizome and other Chinese herbal medicine raw materials, This will significantly increase the use cost of feed additives and affect the palatability (bitter taste), and the use of manganese sulfate, ferrous sulfate, copper oxide and other inorganic trace elements, the absorption efficiency is low, the environmental pollution is greater, and it will also affect the feed. Nutritional value of additives

Embodiment 1～5

[0027] Select 48 "grown up" binary sows with 70 days of gestation, and randomly divide them into 6 groups. The pregnant sows are fed with the pregnant sow feed 555 produced by Nanchang Aonong as the diet, and the pregnant sows are fed 4.5 catties per day. In the diets of the group, the feed additives were added according to the component weight formulas of the feed additives in Table 1, and the amount of feed additives added was 1 kg of feed additives per ton of the diets. Pregnant sows had free access to water, and the litter size, birth weight and weaning weight of the sows were recorded respectively. The test results are shown in Table 2.

[0028] In each embodiment group, the feed additive is prepared by the following method:

[0029] (1) prepare materials according to the parts by weight of the corresponding components in each group of feed additive formulas;

[0030] (2) each component raw material in step (1) is crossed 40 mesh sieves;

[0031] (3) First place the carr...

Embodiment 6

[0040] In this example, the feed additive for pregnant sows includes the following components and parts by weight: 16 parts of 98% lysine, 12 parts of threonine, 5 parts of tryptophan, 8 parts of methionine, 7 parts of arginine 2 parts of multivitamin, 0.6 part of copper methionine, 0.6 part of chelated iron methionine, 0.5 part of zinc glycinate, 0.1 part of yeast selenium, 0.2 part of manganese glycinate and 30 parts of carrier.

[0041] Among them, the composition of multivitamin is: every 1kg contains 20 million IU vitamin A, 2 million IU vitamin D 3 , 30g vitamin E, 20g vitamin C, 1000mg vitamin K, 2g vitamin B 1 , 5g vitamin B 2 , 2g vitamin B 6 , 5mg vitamin B 12 , 800mg folic acid and 500mg biotin, and the rest is system bran.

[0042] The carrier is made by mixing puffed soybeans and zeolite powder, and the specific preparation method is: mix the puffed soybeans and zeolite powder evenly according to the mass ratio of 1:6, and crush until the particle size is 200 ...

Embodiment 7

[0050] In this example, the feed additive for pregnant sows includes the following components and parts by weight: 12 parts of 98% lysine, 3 parts of threonine, 6 parts of tryptophan, 8 parts of methionine, 7 parts of arginine 3 parts of multivitamins, 0.7 parts of copper methionine, 0.8 parts of chelated iron methionine, 0.3 parts of zinc glycinate, 0.07 parts of yeast selenium, 0.2 parts of manganese glycinate and 48 parts of carriers.

[0051] Among them, the composition of multivitamin is: every 1kg contains 20 million IU vitamin A, 2 million IU vitamin D 3 , 30g vitamin E, 20g vitamin C, 1000mg vitamin K, 2g vitamin B 1 , 5g vitamin B 2 , 2g vitamin B 6 , 5mg vitamin B 12 , 800mg folic acid and 500mg biotin, and the rest is system bran.

[0052] The carrier is made by mixing puffed soybeans and zeolite powder, and the specific preparation method is: mix the puffed soybeans and zeolite powder evenly according to the mass ratio of 1:4, and crush until the particle size ...

Abstract

The invention relates to a feed additive used for a pregnant sow. The feed additive comprises the following components in parts by weight: 5-20 parts of 98% lysine, 3-15 parts of threonine, 2-6 parts of tryptophan, 5-20 parts of methionine, 2-9 parts of arginine, 1-3 parts of decavitamin, 0.3-0.8 part of copper methionine, 0.4-1 part of iron methionine chelate, 0.1-0.5 part of zinc glycine, 0.05-0.1 part of selenium yeast, 0.1-0.3 part of manganese glycine and 30-80 parts of a carrier. The preparation method comprises the following steps: preparing the materials in parts by weight, sieving the raw materials with a 40-mesh sieve, then adding to a blender together, stirring and mixing uniformly to prepare the feed additive used for the pregnant sow. Compared with the prior art, the preparation process is simple, complicated raw material pre-treatment process is not needed, the raw materials only need to be sieved and then uniformly mixed, the feed additive is easily absorbed by a pregnant sow body, the use ratio of a feed for feeding the pregnant sow can be also improved, the raw materials are easy in source, and the feed additive is beneficial to popularization and utilization.

Description

technical field [0001] The invention belongs to the technical field of feed additives and relates to a feed additive, in particular to a feed additive for pregnant sows and a preparation method thereof. Background technique [0002] In the field of pig breeding technology, the embryonic development of pregnant sows plays a vital role in the weight of newborn piglets. Due to the enhanced pregnancy metabolism of pregnant sows, the prenatal development of the fetus is slow. Therefore, the sows have very high requirements on the nutritional level during pregnancy, but too high a nutritional level will reduce the feed utilization rate, and at the same time, it will easily make the sows fat, resulting in embryo Mortality increases, and the number of litters is reduced, and even the next reproductive cycle will be affected, and estrus will stop; on the contrary, if the nutritional level is insufficient, it will affect the litter size, the birth weight of the litters, and the milk p...
