Problems to be noticed in the management of livestock and poultry
In livestock and poultry production, some farmers often complain: the same input, the same market, but the benefits of breeding are always worse than others. Careful analysis of the reasons for the gap is often due to the fact that management is not elaborate and does not attach importance to some “small issuesâ€. In fact, correct understanding and handling of "small problems" is a guarantee for creating high efficiency in livestock and poultry breeding. This article introduced some problems that are easily overlooked in the daily management of livestock and poultry raising, and hoped to arouse the attention of farmers. Chicken immunization should not use disinfectant chicken immunization 7 days - 10 days prohibit the use of disinfectants, especially drinking water immunity. If disinfectant is used, it will kill the disease (bacteria) seedlings, leading to immune failure. Chicken pests should not use trichlorfon: chicken bursal alkaline environment, trichlorfon can generate a strong venom dichlorvos, can easily cause poisoning. Therefore, chickens should not be used to insecticide trichlorfon, available flooding spirit, levamisole, etc. have good effect. Chicken eggs should not be immunized during the prosperous period: When the egg is injected at the height of the egg production, it often causes chicken diarrhea, sagging wings, dullness, deprivation, production of soft-shelled eggs or discontinued production, etc. In severe cases, delirium or paralysis occurs, and even death. Therefore, the chickens should not be immunized during the egg production period, and should be carried out during the rest period. 7 days before and after the immunization, vitamin B2, yeast, and cod liver oil should be added to the feed. Eggs should not be washed with water: There is a layer of colloidal protective film on the surface of the eggs, and the water content and germs invade. If the eggshell protective film is washed off with water, the quality of the eggs will be reduced, affecting the hatching rate and the survival rate of the chicks. Therefore, eggs should not be washed with water and should be disinfected with benzalkonium before disinfection. Egg sheds should not be disinfected with quicklime: Quicklime disinfection of chicken coops will cause chicken toe burns; eating lime into the gastrointestinal cause gastroenteritis, edema, ulcers; stimulate the occurrence of respiratory diseases. Therefore, it should not be disinfected with quicklime and can be formulated as a 10%-20% lime emulsion sprayed chicken house. Furazolin should not be added to the drinking water of chickens: Furazolin is almost insoluble in water and easily precipitates in water. If chickens are added to drinking water, they can easily cause poisoning. Should be fed with spices, stir evenly. The first generation of hybrid pigs could not be used for breeding: the first generation hybrid pigs had strong resistance to disease and were resistant to roughage, but were not suitable for breeding. As the advantage of hybridization is gradually weakened, the offspring individuals are small, and the disease resistance is weak, causing losses to production. The buckwheat tree should not be planted around the pig house: The root bark and fruit of the buckwheat tree contain chemical components such as bupropion, neutral resin, etc. If the pig mistakenly eats fresh root bark or 100 g of fruit to cause poisoning, treatment is not timely and easy. death. For this reason, buckwheat trees should not be planted around the house. Potato stalks should not be fed to pigs: Solanine and nitrate are contained in the skin, shoots, and leaves of potatoes, and pigs are susceptible to excessive consumption. Potato stems and leaves for feed to feed pigs must be cautious, control the amount, now boiled and fed, but can not cook Shabu Guo, or easily cause poisoning. Feed additives for livestock and poultry cannot be “better and betterâ€: Many farmers believe that the more feed additives there are, the more effective they are. In fact, the vast majority of additives are used in excessive quantities, but they are harmful and inhibit livestock growth and even poisoning. For this reason, the use of additives should be reasonable and controlled. Disinfection of livestock and poultry pens should not use pesticides: Dimethoate, trichlorfon, organic phosphorus and other pesticides have a killing effect on crops, flies, etc., and have no killing effect on bacteria and other pathogens, but are only harmful to livestock and poultry. Therefore, disinfection of the pens should not be used pesticides, available 10% -20% of fresh lime milk, 5% -10% bleach and other disinfectants. Young livestock should not use norfloxacin: norfloxacin for long-term development of young animals. Therefore, it is not appropriate to feed norfloxacin in feed during the growth and development period of young livestock and poultry to protect the normal development of bones. The feed of cakes and pans should not be directly fed to livestock and poultry: cakes, cotton cakes, cakes and other cakes contain toxic substances, and they are fed directly to livestock and poultry to reduce the utilization of protein and cause gastrointestinal diseases and even poisoning. Therefore, the feed for the cakes should be processed and fed to livestock and poultry, and the dosage should be strictly controlled. It is not appropriate to add urea to cows in summer and autumn: Urea is a good protein supplement for cattle, but it is suitable for wheat and other feeds in winter and spring. In summer and autumn, the blue-green material and seed material are abundant. If urea is added, the rate of urea synthesis of protein will be reduced, affecting weight gain, and even playing the opposite role. Mild straw should not be fed cattle: cattle eat moldy straw, coupled with excessive labor, malnutrition, easy to cause poisoning. The main performance of hoof leg edema, lameness and so on. Protect the health of grazing cattle and do a good job of storage and storage of rice straw. Cattle should not be fed cooked food: bovine ruminants, feed must be ruminated to digest and absorb. If you often feed cooked food is not conducive to rumination, but also easy to cause ruminal acidosis. Rabbits should not be natural mating: natural mating is conducive to promoting the female estrus period, and timely breeding to prevent leakage. But it is easy to reduce the useful life of rabbits, reduce the conception rate and birth rate, cause inbreeding, early pregnancy and early mating, variety degradation, affect the growth of young rabbits, and spread disease. Therefore, rabbits should not be naturally mated. Pregnant rabbits should not feed oxytetracycline: Many rabbit farmers often mix terramycin in feed to prevent disease. Because oxytetracycline can easily cause stillbirths and deformed fetuses and reduce reproductive ability, it is inappropriate for pregnant rabbits to feed oxytetracycline. Male rabbits should not always feed additives: Commonly used additives for male rabbits used for breeding, will appear snooze, less exercise, reduce the ability to match. Therefore, male rabbits should not be fed with additives. The rice bran should not be over-eating rabbits: more than 30% of the rice bran in the diet will affect the quality of the rabbits and cause dermatitis; the body condition of the rabbits will be too fat and reduce reproductive performance. Therefore, rice bran does not exceed 25% to 30% in the diet, and it is reasonable to use crude rice. Silage should not feed rabbits: silage acidity, feeding rabbits cause indigestion, and even cause acidosis. Therefore, silage should not feed rabbits. Frozen vegetables should not be fed rabbits: rabbits fed frozen vegetables affect chewing, digestive disorders, is not conducive to the absorption of nutrients, causing gastroenteritis, dysentery and so on. The frozen vegetables are chopped and mixed with bran and cornmeal. Pig chicken additives should not be fed rabbits: Many rabbit farmers fed pig chicken additives to rabbits, and the results could not reach the goal. Because the pig chicken additive is formulated according to the growth and development characteristics of the pig chicken, its digestive function is different in each segment. Pig chicken additives should not be fed to rabbits, the amount of harmful, the application of rabbit additives.
