Abstract

The invention provides a kind of mixed fodder that improves sow milk output, it contains vitamin, organic trace element, carrier, and contains by weight percentage following composition: arginine: 30%-40%, valine: 25%-35%. The present invention for sow gestation 80 days to sow weaning stage. This pre-mixing agent mainly contains following component: multivitamin, organic trace elements, carrier, especially contain arginine and valine. Compared with conventional pre-mixing agent, product of the present invention contains arginine and valine, after bulk raw material corn, dregs of beans, fish meal, expanded soybean combination, can effectively improve piglet birth and weigh and the sow output of milk.

Description

A kind of mixed fodder that improves sow milk output and preparation method thereof

Technical field

The present invention relates to a kind of feed, is mainly vitamin, trace element and amino acid premixed feed for the milking sow stage.

Background technology

Sow is in the lactation stage, and vitamin is the necessary nutrient of sow, and reasonably vitamin level is extremely important to high yield sow. Because people are clear not to the function understanding of liposoluble vitamin, sow produces subnumber and lactation amount is puzzlement Swine Production person's a difficult problem always, wherein vitamin A plays an important role in breeding function, and vitamin E maintains permeability of cell membrane and bringing into play important anti-oxidation function in sow mammary gland; And the lactating sow daily ration of corn bean pulp type lacks valine conventionally, need to additionally supplement. At latter half of gestation, due to arginine deficiency, cause piglet birth weight to decline, therefore to improve piglet birth and weigh, sow lactation amount just need to supplement valine and arginine in daily ration; Can efficiently provide arginine and valine by plasma protein.

Summary of the invention

The vitamin, trace element and the amino acid premixed feed that the invention provides a kind of milking sow stage, be intended to improve piglet birth weight and the sow output of milk.

For achieving the above object, technical solution of the present invention is：

The present invention proposes a kind of vitamin, trace element and amino acid whose pre-mixing agent, for sow gestation 80 days to sow weaning stage. This pre-mixing agent mainly contains following component: multivitamin, organic trace elements, carrier, especially contain arginine and valine.

The usefulness of technique scheme is:

The present invention is compared with conventional pre-mixing agent, and product of the present invention contains arginine and valine, after bulk raw material corn, dregs of beans, fish meal, expanded soybean combination, can effectively improve piglet birth and weigh and the sow output of milk.

Detailed description of the invention

Below in conjunction with specific embodiment, content of the present invention is further described. The every research and development person of experimental condition of the present invention can need to adjust accordingly according to the design of oneself, and is not limited to the experimental condition of the present embodiment.

Embodiment 1

Concrete proportioning and process conditions are as table 1

Embodiment 2

Embodiment 3

Embodiment 4

Test method:

Test one:

160 body weight body weight (150 ± 10kg), parity (the 2nd tire) and the approaching in-pig (binary of growing up) of date of parturition are divided into 8 groups at random, from pregnant 90d start the to feed daily ration of 4 kinds of varying level vitamin Es, be respectively 30mg/kg, 60mg/kg, 120mg/kg, 240mg/kg; In 4, the daily ration of varying level vitamin A, is respectively 4000IU/kg, 8000IU/kg, 16000IU/kg, 20000IU/kg. Experimental basis daily ration is in table 1. Experimental period, finishes in the time that piglet 25d weans, and duration of test is measured every sow born weight, weight of weaning litter and litter size.

Pregnant 90 days time, make to test the obstetric table of sow Engage of standard, freely drink water, feed intake 3.0kg/ days. Vaccine and feeding and management are carried out with reference to conventional commodity pig farm binary sow feeding management code.

Test daily ration obtains the vitamin a level of design by adding the alternative interpolation of required vitamin(e) A acetate pre-mixing agent moderate zeolite powder.

Adopt the ANOVA process analysis test data in SAS9.0, and with Duncan formula multiple ratio, the level of signifiance 0.05. Screen best proportioning.

When off-test, eachly repeat to extract 2 of medium body weight sows, venous blood collection, adopt the full-automatic subclassification blood counting instrument of SE-9000 to measure red blood cell, leucocyte and amount of mononuclear cells, content of hemoglobin and packed cell volume in blood, prepare serum, by SABC immunohistochemical staining kit and method, measure T lymphocyte CD 4, CD8 subgroup ratio and CD4/CD8 ratio in serum.

Result of the test:

Conclusion:

By the analysis to production performance and Biochemical Indices In Serum, result shows, the optimum level of vitamin E in daily ration is 120mg/kg, and the optimum level of vitamin A in daily ration is 16000IU/kg.

Pharmacology analysis:

Vitamin A promotes the biosynthesis of protein and the differentiation of osteocyte. In the time that it lacks, between Gegenbaur's cell and osteoclast, balance is destroyed, or strengthens and make sclerotin hyper-proliferative because skeletonization is movable, or established sclerotin is not absorbed. If sow hypovitaminosis A, can directly affect development of fetus, even there is stillborn foetus. Vitamin A contributes to cell proliferation and growth. When animal is deficient in vitamin A, obviously there is growth retardation, may decline relevant with the reduction of animal appetite and protein utilization rate. When VAD, affect buck spermatic cord epithelium and produce sperm mother cell, the female vagina epithelium cycle changes, and also affects placenta epithelium, embryo is formed and be obstructed. VAD also causes the activity decreased that forms needed enzyme such as catalysis progesterone precursor, and the generation of steroids in adrenal gland, gonad and placenta is reduced, and may be the reason that affects reproductive function.

Vitamin E is tocopherol, can promote sex hormone secretion, and female hormone Enrichment improves reproductive capacity, prevention of miscarriage. When TD, there will be ovarian atrophy and epithelial cell sex change, breed abnormal. Thereby vitamin E can be protected T lymphocyte, protection red blood cell, Green Tea Extract oxidation, suppress the danger of platelet aggregation reduction myocardial infarction and cerebral infarction. Also, to burn, frostbite, capillary hemorrhage, vitamin E can suppress the lipid peroxidation reaction in eye lens, makes peripheral vessel expansion, improves blood circulation.

Note: vitamin A, neo dohyfral D3, vitamin E, vitamin K, vitamin B1, vitamin B2, pyridoxamine, cobalamin, nicotinic acid, pantothenic acid, folic acid, the vitamins such as biotin are referred to as multidimensional pre-mixing agent, and the adding proportion in sow pre-mixing agent can be 15%-30%, and the present invention preferably 20%.
