Abstract

The invention provides a mixed feed for increasing sow milk yield. The mixed feed contains vitamins, organic trace elements and a carrier, and also contains the following components by weight percent: 30-40% of arginine and 25-35% of valine. The mixed feed is used from the sow gestation period of 80 days to the sow weaning period. The premix mainly contains the following components: the vitamins, the organic trace elements and the carrier, and especially contains arginine and valine. Compared with the conventional premix, the product provided by the invention contains arginine and valine, and the piglet birth weight and the sow milk yield can be effectively increased after the product is combined with a large amount of raw materials-maize, bean pulp, fish meal and expanded soybean.

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, mainly is vitamin, trace element and amino acid premixed feed at the milking sow stage.

Background technology

Sow is in the lactation stage, and vitamin is the necessary nutrient of sow, and reasonably the vitamin level is extremely important to the high yield sow.Because people are clear inadequately 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 is kept permeability of cell membrane and brought into play important anti-oxidation function in sow mammary gland; And the lactating sow daily ration of corn dregs of beans type lacks valine usually, needs additionally to replenish.At latter half of gestation, because the arginine deficiency causes the piglet birth weight to descend, therefore to improve the piglet birth and weigh, the sow lactation amount just need replenish valine and arginine in daily ration; Can efficiently provide arginine and valine by plasma protein.

Summary of the invention

The invention provides vitamin, trace element and the amino acid premixed feed in 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, is used for sow gestation 80 days to the sow weaning stage.This pre-mixing agent mainly contains following component: multivitamin, multiple organic trace element, carrier, especially contain arginine and valine.

The usefulness of technique scheme is:

The present invention compares 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 improve the heavy and sow output of milk of piglet birth effectively.

The specific embodiment

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 adjust accordingly according to the design needs of oneself, and is not limited to the experimental condition of present embodiment.

Embodiment 1

Concrete proportioning and process conditions such as table 1

Test method:

Test one:

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

Gestation made the test sow enter standardized obstetric table in the time of 90 days, freely drank water feed intake 3.0kg/ days.Vaccine and feeding and management are carried out with reference to the commodity pig farm binary sow feeding management rules of routine.

The test daily ration substitutes the vitamin a level that interpolation pre-mixing agent moderate zeolite powder obtains to design by adding required vitamin(e) A acetate.

Adopt the ANOVA process analysis test data among the SAS 9.0, and with Duncan formula multiple ratio, the level of signifiance 0.05.Screen best proportioning.

During off-test, each repeats 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 the blood, preparation serum, with SABC immunohistochemical staining kit and method, measure T lymphocyte CD 4, CD8 subgroup ratio and CD4/CD8 ratio in the serum.

Result of the test:

Conclusion:

By the analysis to production performance and serum biochemistry index, the result shows that 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.When it lacked, balance was destroyed between Gegenbaur's cell and osteoclast, or owing to the movable enhancing of skeletonization makes the sclerotin hyper-proliferative, or established sclerotin is not absorbed.If the sow hypovitaminosis A can directly influence development of fetus, even stillborn foetus takes place.Vitamin A helps cell proliferation and growth.When animal is deficient in vitamin A, growth retardation obviously occurs, may descend relevant with the reduction of animal appetite and protein utilization rate.During VAD, influence buck spermatic cord epithelium and produce sperm mother cell, the female vagina epithelium cycle changes, and also influences the placenta epithelium, the embryo is formed be obstructed.VAD also causes the activity reduction that forms needed enzyme such as catalysis progesterone precursor, and the generation of steroids in adrenal gland, gonad and the placenta is reduced, and may be the reason that influences reproductive function.

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

Annotate: vitamin A, cholecalciferol, vitamin E, vitamin K, vitamin B1, vitamin B2, vitamin B6, cobalamin, nicotinic acid, pantothenic acid, folic acid, vitamins such as biotin are referred to as the multidimensional pre-mixing agent, and the adding proportion in the sow pre-mixing agent can be 15%-30%, and the present invention preferred 20%.
