Description

Nonreactive premix for later-period feed of dry-fed meat ducks and use method thereof
Technical Field
The invention belongs to the technical field of animal feeding, and particularly relates to an antibiotic-free premix for later-stage feed of dry-fed meat ducks and a using method thereof.
Background
Duck is an indispensable meat food in daily life of people, is also a delicious dish, is suitable for nourishing, is a main raw material of various delicious famous dishes, and has a ancient character: the duck meat is delicious and is favored by the domestic ducks. The duck meat has much higher protein content than livestock meat, moderate fat content, uniform distribution, and good taste. Contains more vitamins B and vitamin E than other meat, and has effects in resisting beriberi, neuritis and various inflammations, and resisting aging. Duck meat contains rich nicotinic acid, which is one of two important coenzymes in human body and has protective effect on heart diseases such as myocardial infarction.
Meat duck breeding is one of traditional breeding. The addition of antibiotics in the feed has become a habit of livestock breeding, however, the long-term use of antibiotics can cause serious harm to livestock: firstly, drug-resistant bacteria are generated in an animal body, so that cellular immunity and humoral immunity are inhibited, the immune cell function of the animal body is seriously damaged, the immunity and disease resistance of the animal are reduced, and even the immune failure is caused; secondly, the excessive use of antibiotics in the feed, the additive and the veterinary drug can enter the human body through a food chain, so that people indirectly contact the antibiotics, the effect of the treatment with the antibiotics disappears when the human body is ill, and meanwhile, the antibiotics destroy intestinal microorganisms to influence the digestion capability of animals on nutrient substances and the growth performance of the animals; third, some antibiotics themselves have toxic effects, such as streptomycin, kanamycin, gentamicin, polymyxin, and the like.
The abuse of antibiotics causes pathogenic bacteria to generate drug resistance, causes the imbalance of animal intestinal flora, reduces the immunity and influences the production performance and the product quality. The micro-ecological live bacteria become relatively ideal products for replacing antibiotics. However, some common microecologics in the current market are still limited in popularization and application due to the influence of temperature, pH value, antibiotic intolerance and the like.

Feeding experiment
1. Test method
The test selects the 4000-feather 14-day-old cherry valley meat ducks (half of male and half of female) with the body weight of about 640g (P >0.05), and carries out corresponding immunization programs.
Experimental groups: the large material prepared in the embodiment 1-5 of the invention;
control group: the macro-aggregate prepared in comparative examples 1-5;
basic macro-ingredient formula: 330 parts of corn, 215 parts of barley, 50 parts of wheat, 120 parts of 43% soybean meal, 75 parts of brewer's grains, 50 parts of corn fiber, 50 parts of corn germ meal, 20 parts of palm kernel meal, 40 parts of soybean oil, 10 parts of bentonite, 12 parts of stone powder and 8 parts of calcium hydrophosphate.
2. The test ducks were randomly divided into 10 groups, 5 experimental groups, 5 control groups, 2 replicates each, and 200 feathers each. The raising mode is dry raising in a ground fence, has the measures of sun protection, rain protection, heat preservation and temperature reduction, and is characterized in that each repeated group is fed independently, and the test ducks are fed with free food and water during the test period. The pre-test period is 7 days, and the main test period is 21 days. During the test, the room temperature is controlled to be 22-25 ℃, feeding and related vaccine immunization are carried out according to a conventional feeding mode, and the total feed consumption of each repetition is recorded every day. The influence of each feed on the production performance of the meat ducks is detected by counting indexes of 14-day-old weight, 42-day-old weight, death and culling number, survival rate, total weight gain, total feed consumption and feed-meat ratio of the meat ducks, and scientific basis is provided for production and utilization. The results of the effect of each macro-material on the production performance index are shown in the following table.
Figure BDA0003321948110000131
Figure BDA0003321948110000141
As can be seen from the above table, example 5 is the most preferred example, and compared with comparative example 1, each index is improved, and it can be seen that the non-premix formula can completely replace the premix formula with the premix in the production practice. Compared with the comparative example 2, the indexes of the example 5, the comparative example 2, the comparative example 3 and the comparative example 4 are all improved, and in the indexes of 3 indexes of 42 days old weight, total weight gain and total material consumption, the synergistic effect of the example 5 relative to the comparative example 5 is more than 10% higher than the sum of the synergistic effects of the comparative examples 2-4 relative to the comparative example 5. This is due to: the feed additive mainly comprises macleaya cordata powder, tributyrin and gamma-aminobutyric acid, wherein the tributyrin mainly supplies energy to the intestinal tract, repairs the intestinal tract and resists stress, and can be matched with digestive enzyme to improve the digestibility of nutrient substances and promote the growth of animals, so that the growth-promoting antibiotic in the feed is finally replaced; the gamma-aminobutyric acid maintains the regulation of the center on each system of the organism, and the growth of pituitary gland, thyroid gland and the like and the secretion of hormone are influenced, so that the secretion of the growth hormone is increased, and the growth is promoted; particularly, the pancreatic lipase secretion of pancreas can be promoted, so that the decomposition of tributyrin is promoted; macleaya cordata powder mainly plays roles in regulating intestines, resisting inflammation and promoting growth, and the macleaya cordata powder mainly contains sanguinarine which is not easy to be absorbed by organisms, more than 98 percent of sanguinarine is discharged in an original substance form, and the rest macleaya cordata powder is metabolized by livers, acts on digestive tracts and is absorbed by gastrointestinal tracts, enters blood plasma, can improve the oxidation resistance of the organisms and has no influence on small intestine mucosal epithelium; tributerol butyrate and gamma-aminobutyric acid can regulate intestinal tracts, provide energy for organisms and stimulate hormone secretion, so that sanguinarine absorption and digestion are promoted.
In conclusion, the overall production performance of the test group is superior to that of the control group, the weight gain effect is obviously increased, the disease resistance is enhanced, the feed-meat ratio is reduced, and the survival rate is improved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
