Description

Composite microecological preparation for epidemic prevention of suckling pigs
Technical Field
The invention belongs to the field of composite microecologics in the field of breeding, and particularly relates to a composite microecologics for epidemic prevention of porkets.
Background
Suckling pigs refer to piglets which have not yet been completely weaned, generally pigs born less than two months. In the process of weaning the suckling pigs, due to the fact that the suckling pigs are often influenced by factors such as hunger and stress, overfeeding is very easy to cause diarrhea, and therefore feeding is seldom carried out, on one hand, freshness of feed can be guaranteed, appetite can be increased, the appetite of the suckling pigs can be effectively stimulated, feed intake can be increased, the digestion capacity of the suckling pigs can be exercised as soon as possible, and the fastest growth speed is guaranteed. Meanwhile, clean drinking water is provided, and the trough is guaranteed to be clean. The feeding method of free feeding is adopted immediately after weaning, but the method is not beneficial to improving the feed intake of the suckling pigs.
For selecting the piglet feed, on one hand, the piglet feed needs to be considered from the surface, such as easy digestion, no diarrhea and large feed intake; on the other hand, the growth performance needs to be evaluated, and for the suckling pigs, the most important is the growth speed of the suckling pigs, the suckling pigs grow fast, and the marketing time of the whole fattening period is shortened. Therefore, the choice of piglet feed is very important for the growth of the piglets. The existing commercial suckling pig feed can ensure the growth speed of suckling pigs to a certain extent, but cannot provide enough nutrient substances for the suckling pigs, so that the suckling pigs have poor resistance, are easily interfered by diseases, and sometimes cannot even survive.
Based on this, chinese patent CN103444784B discloses a compound microecological preparation for adjuvant epidemic prevention of live pigs, which can block the transmission of pathogenic bacteria in ecological pig farms, thereby improving the disease resistance of live pigs, but the preparation can not block the pathogenic bacteria infection well, only reduces the transmission process, and the preparation is generally suitable for pigs after weaning completely, while the suckling pigs need to be more careful in the feed selection process due to poor resistance per se.
Meanwhile, the chinese patent application CN105285399A discloses a liquid composite microecological preparation for piglets and a preparation method thereof, wherein the composite microecological preparation is developed by enhancing the stability of microecological preparations, especially the stability of lactic acid bacteria, through chitosan oligosaccharide aiming at the characteristics of piglet intestinal flora development and piglet feeding management, and can effectively maintain the balance of strains in vivo, but cannot resist the infection of external bacteria and viruses, easily causes various diseases, and causes harm to the body of pigs.
In conclusion, the prior art generally lacks a microecological preparation which can be used for epidemic prevention of the suckling pigs, so that the resistance of the suckling pigs to foreign germs is improved, and the occurrence of diseases is reduced.

2. test animals: 70 piglets which are born for half a month and have the weight of 15 +/-1 kg are averagely divided into 7 groups of 10 pigs, and the following requirements are met: each pig is healthy and has no hereditary diseases;
3. the test method comprises the following steps: the complex probiotics prepared in examples 1-3 and comparative examples 1-3 were added as feed additives to the piglet care concentrate, and the ratio of the two was 6: 94, feeding 12kg of the test feed described in examples 1-3 and comparative examples 1-3 per group per day, feeding only the piglet nursing concentrated feed to the control group, renewing the feed per day, freely drinking water, continuously measuring the weight and the food intake 2 times per day for 10 days, calculating the average weight, the weight gain, the total food intake and the food utilization of the piglets in each group at the end of the test, and taking the average values as the final weight; daily gain and daily food intake were averaged over 10 animals per group.
4. And (3) test results: the specific test results are shown in table 1.
Figure BDA0002701340580000081
As can be seen from Table 1, the daily gain of the experimental group, to which the feed prepared according to examples 1-3 of the present invention was added, was significantly increased and the average daily food consumption was not greatly different from that of the control group, indicating that the digestive absorption capacity of the piglets fed with the feed of examples of the present invention was higher, particularly the daily gain of 736.42g in example 3, which is the best example of the present invention, whereas the digestive absorption capacity of the comparative examples 1-4 was significantly decreased due to the removal of allicin, which is caused by the change of the ingredients of the digestion promoter.
Test example 2 resistance test
1. Test samples: composite probiotics prepared in examples 1 to 3 and comparative examples 1 to 8; concentrated piglet nursing feed purchased from Henan and North agricultural big feed Co., Ltd, license number: (2015) 01092; alpha-hemolytic streptococcus, beta-hemolytic streptococcus available from Shanghai-Yizhao Biotechnology Ltd;
2. test animals: 120 male piglets, with body weight of 15 ± 1kg, were evenly divided into 12 groups, requiring: the health is good, and no obvious genetic disease exists;
3. the test method comprises the following steps: the complex probiotics prepared in examples 1-3 and comparative examples 1-3 were added as feed additives to the piglet care concentrate, and the ratio of the two was 6: 94; mixing alpha-hemolytic streptococcus and beta-hemolytic streptococcus according to the weight ratio of 1: 1 mixing to obtain mixed bacterial powder.
The experiment is divided into an experiment group and a control group, the experiment group is fed with the feed added with the composite microecologics of the invention in examples 1-3 and comparative examples 1-8 every day, the control group is fed with the concentrated feed for nursing the ordinary suckling pigs, and enough feed is fed every day for freely drinking water and eating; meanwhile, 200mg of the mixed bacterial powder (completely eaten) was administered twice a day for 10 consecutive days to each group of suckling pigs. After continuous 3 months, the immunopotentiation effect on the suckling pigs was observed. The immune enhancement index is determined by measuring leukocytes in blood collected from pigs before and after administration of the "mixed bacterial powder"; the average value of each group was taken as the final value.
White blood cell change value-final white blood cell number-initial white blood cell number.
4. And (3) test results: the specific test results are shown in Table 2.
