Effect of microecological preparations on piglet rearing

Modern animal husbandry characterized by intensive farming, in order to maintain the "health" of animals, in the face of environmental degradation, disease transmission, the abuse of antibiotics seems to be the only choice. The deterioration of the breeding environment and the abuse of antibiotics pose a great threat to animal production, food safety and the environment.

The probiotics contained in the microecological preparations are gradually being widely used in pig production for their superior performance. It has improved pig health, improved production performance, prevention and control of diarrhea, improved sow constipation, reduced ammonia concentration in livestock houses, and reduced production costs. At present, microecological preparations are gradually accepted by the majority of farm owners. Ryz China Feed Industry Information Network - based on feed, serving animal husbandry

1. Experimental method. Ten sows with similar breeds, parity, body weight, age and childbirth were randomly divided into two groups. The experimental group and the control group were basically consistent with the management conditions of the real animals. After the production of the sows in the experimental group, 5 ml of the health liquid containing bifidobacteria was administered before the milking, and the milk was fed 2 hours later, and on the third day, once again, 5 ml per head. According to the routine prevention method, the control group was fed with mother and child before and after delivery. The piglets' feces, spirit, appetite, and onset were recorded daily, and the average birth weight of the piglets and the average weaning weight of 30 days old were measured.

2. Experimental results. A total of 36 piglets were tested in the experimental group, 1 in the jaundice, and 3 in the white sputum. The protection rates were 97.2% and 91.6%, respectively. In the control group, 32 piglets were tested, 3 of the jaundice, and 3 of the white sputum, and the protection rates were 90.6% and 90.6%, respectively. Weight gain effect on piglets: The average litter weight of the experimental group increased by 8.71 kg compared with the control group. All the above results show that the use of microecological preparations has a good effect on piglet production. Ryz China Feed Industry Information Network - based on feed, serving animal husbandry

(B) the characteristics of microecological preparations ryz China feed industry information network - based on feed, service animal husbandry

1. Regulate the intestinal environment and maintain the intestinal micro-ecological balance. The diseases that occur in pig breeding, whether they are viral diseases or bacterial diseases, are basically caused by intestinal diseases. The microecological preparations inhibit the reproduction of harmful bacteria by colonizing, breeding and secreting antibacterial substances in the intestinal tract to maintain the balance of intestinal flora. There are reports in foreign countries that feeding newborn piglets with Lactobacillus, the ratio of Lactobacillus and E. coli in feces reaches 1280:1, and the proportion of Lactobacillus not fed is 2:1, which leads to beneficial bacteria. It can effectively prevent the colonization of enteropathogenic Escherichia coli in the intestine. Ryz China Feed Industry Information Network - based on feed, serving animal husbandry

2. Enhance the immune function of animals. Lactobacillus is a good non-specific immunopotentiator, which can activate the systemic immune system through the lymphatic circulation, stimulate the body's humoral immunity and cellular immunity, induce the body to produce interferon and other cytokines, and improve the body's local immune function, thus resisting the wild-type infection. .

At the same time, the microecological preparation has a synergistic effect with the specific vaccine immunization. If it is used in combination with the vaccine, the non-specific and specific immunization can be effectively combined, and the effect of preventing the disease can be greatly improved.

3. It takes a long time to work in animals. Microecological preparations are different from drugs such as antibiotics, but need to colonize and proliferate in the intestines, and rely on metabolites. However, this process takes a certain time, so it is necessary to add long-term feed or drinking water in pig production. The effect will be obvious.

4. Strong adaptability to the environment. The microecological preparation is suitable for various dietary ingredients, and it is resistant to high temperature, acid and alkali, and granulation resistance. The requirements for the ring mirror are lower. Ryz China Feed Industry Information Network - based on feed, serving animal husbandry

(3) Factors affecting the effectiveness of micro-ecological additives ryz China Feed Industry Information Network - based on feed, serving animal husbandry

The use of micro-ecological additives to improve the production level of pigs has been recognized by feed enterprises and farms, but there are also reports of ineffective or negative effects. The reason is that microecological preparations are often affected by some factors in production and use. The product factors include: species, number of viable bacteria in the product, source of the strain, production process, etc.; feed factors include: animal species, feeding stage, physiological state, intestinal flora status, etc.; Etc., will affect the function of beneficial micro-organisms. Therefore, in the selection and use of micro-ecological preparations, it is necessary to analyze the above factors in detail, and based on a detailed understanding of the products, scientific selection and rational use can be made.
