Abstract
The invention discloses a sow mixed feed improving the reproductive performance of pregnant sows and a preparation method of the sow mixed feed. The sow mixed feed comprises the following components in parts by weight: 55-60 parts of corn, 3-8 parts of barley, 12-17 parts of bran, 2-5 parts of fish meal, 4-8 parts of corn DDGS, 4-6 parts of bean pulp, 1-1.5 parts of calcium hydrophosphate, 0.5-1 part of limestone powder, 1-2 parts of bentonite, 0.2-0.5 part of lysine, 0.5-1 part of arginine, 0.1-0.3 part of methionine, 0.1-0.3 part of threonine, 0.1-0.3 part of choline chloride, 0.5-1 part of an aspartic acid, 0.05-0.1 part of an acidifier, 0.01-0.05 part of a microbial preparation, 0.3-0.5 part of salt, and 1-2 parts of a premixture. The sow mixed feed and the preparation method can balance the level of the amino acid in a sow, increase the amino acid and energy level, improve the immunity and the anti-stress ability of the sow, reduce the residue of toxins and harmful germs in a sow body, reduce the sow constipation, and further improve the reproductive performance of the sow.
Description
Technical field
The present invention relates to broad sow mixed feed and preparation method thereof, belong to mixed feed technical field, refer in particular to a kind of sow mixed feed improving reproduction performance of gestation sow and preparation method thereof.
Background technology
Along with the continuous increase of feeding cost, the reproductive performance of sow is more and more paid attention to by culturist, the height of sow reproductive performance directly determines the economic benefit on pig farm, and the adventive reproductive performance that current intensive pig production place is raised is generally poor, adding the deficiency of managerial skills and the restriction of working condition, there is a certain distance in the production capacity making us current and advanced international standard.Sow is comparatively large to the demand of each nutriment in pregnancy, the deficiency of nutrition add in production management process various stress, have a strong impact on the reproductive performance of sow.But also do not have effective feed to change this phenomenon at present.
On the other hand, research shows, aspartic acid is the synthesis precursor of the amino acid such as lysine in organism, threonine, isoleucine, methionine and purine, pyrimidine bases, participates in many metabolic pathways as supplier amino in organism; Meanwhile, aspartic acid is the main energy sources of chitling mucous membrane, can provide energy for the many metabolic processes of enteron aisle; In addition, aspartic acid also has certain immunization, can alleviate the intestinal tract injury that stress of baby pigs caused ablaction causes, but have not been reported in sow mixed feed.Acidulant can rationally reduce alimentary canal PH, improves the activity of digestive ferment, improves the digestibility of palatability and nutrient, increases immunity and anti-stress ability.Microorganism formulation can improve intestinal microflora, suppresses the generation of harmful bacteria, reduces intestinal contents corrupt, reduces environmental pollution, improves prevention of sow constipation.Therefore, how these components are carried out the purpose that effective proportioning is patent application of the present invention.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of sow mixed feed improving reproduction performance of gestation sow is provided, this mixed feed can balance sow vivo acid level, increase amino acid and energy level, improve immunocompetence and the anti-stress ability of sow, reduce the residual of sow vivotoxin and harmful bacteria, reduce prevention of sow constipation, and then improve the reproductive performance of sow.

This test is carried out on commodity pig farm, Maoming City, and it is close that body weight is chosen in test, and parity is the length × large Suprapubic arch sling 50 of 2-6 tire, test-tube mode is adopted to breed, be divided into 2 groups by body weight and parity, often organize 25 repetitions, each repetition 1 pig.Test group adopts mixed feed of the present invention, with the addition of 1% aspartic acid, 0.07% compound acidulant and 0.03% complex microorganism preparations, control group fed basal diet, carries out process such as nitrogen such as grade with alanine.Test is from insemination of sows to childbirth.
3. feeding and management
Before test, thorough cleaning and sterilizing is carried out to pig house and hopper, adopt gravity-flow ventilation and mechanical assistance to ventilate, test sow 2 first hurdle ground stable breeding, free choice feeding and drinking-water before breeding.After breeding, proceed to positioning rail, feed stage by stage, increase scale of feeding gradually, ensure that feed and drinking-water clean.Childbirth proceeds to childbirth house the last week, and limit is raised, and freely drinks water.Vaccine inoculation is carried out according to pig farm immune programme for children.In whole experimental stage, two processed group carry out feeding and management by identical keeper.Whole process record test pig constipation situation, with gestation 107 days determination test sow thickness of backfats after breeding, gestation 107 days by 10mL syringe jugular vein blood collection, separation of serum, measure sow blood parameters and Antioxidant Indexes, all biochemical indicators and Antioxidant Indexes all adopt kit measurement, and kit is purchased from Nanjing and builds up Bioengineering Research Institute, and preparation of reagents and the equal by specification of operating procedure carry out.
4. Data Collection
Record every sows farrowing sum, number born alive, weigth at birth, the son that lives individual average weight, the thickness of backfat, blood parameters and Antioxidant Indexes, constipation situation.
5. statistical analysis
The data obtained adopts SPSS17.0 to carry out independent sample T inspection, and result adopts mean value ± standard error to represent, using P<0.05 as significance of difference standard.
6. result of the test
Table 2 mixed feed of the present invention is on the impact of sows farrowing situation and nutrition condition
Note: shoulder mark lowercase difference of going together represents significant difference (P<0.05), and nothing shoulder mark then represents that difference is not significantly (P>0.05), and following table is same.
As shown in Table 2, test group is lived, and son is total, always litter weight and young litter weight of living significantly improve (P<0.05), single sows farrowing sum improves 0.72, young individuality of living on average brings up again high 0.03kg, but difference significantly (P>0.05), does not show that the present invention can improve sows farrowing performance; Before breeding, the thickness of backfat is without significant difference, and gestation 107 days test group thickness of backfats are significantly higher than control group (P<0.05), show that the present invention can improve sow nutrition condition.
Table 3 mixed feed of the present invention is on the impact of sow blood parameters and Antioxidant Indexes
As shown in Table 3, test group sow blood albumin, globulin, superoxide dismutase and glutathione peroxidase content are all significantly higher than control group (P<0.05), show that the present invention can improve sow gestation phase immunocompetence and anti-stress ability.
Table 4 mixed feed of the present invention is on the impact (unit: head) of prevention of sow constipation
As shown in Table 4, in the whole gestational period, test group constipation situation is all better than control group, shows that the present invention can improve the constipation situation of sow gestation phase.
In sum, the present invention effectively can improve the reproductive performance of in-pig.
