1. Analysis of the reasons why sows have little or no milk (1) Nutritional level and feed quality are the main factors that affect lactation, especially if a higher nutritional level is given during pregnancy, it will reduce the lactating sow's lactation; if a lower nutritional level is given, the sow will lose weight More, breast dysplasia. (2) Generally, the lactation ability of primiparous sows is lower than that of multiparous sows. The mammary gland development of primiparous sows is not yet perfect, lack of experience in feeding piglets, stimulates the piglets to suckle, often in a state of excitement or tension, milk expression is slow, the milk production of […]

Raising chickens is a delicate task, especially broiler chickens, which will be released for slaughter in just a few dozen days. Therefore, no errors are allowed during the entire breeding process. Even if there is a mistake in feeding management, it will have an impact on the final production performance, such as increased feed-to-meat ratio, substandard weight, increased rate of dead hunting, uncontrollable disease, and even forced to market early, etc., which will eventually lead to direct breeding failure. Affect economic benefits. Therefore, it is necessary to continuously summarize experience and learn lessons during the breeding process. In actual operation, try to be as reasonable and accurate as possible to

A chicken farmer asked us today, saying that his chickens have no appetite, they like to drink water, their bodies are weak and uncoordinated, and their crops are larger than normal chickens. Anatomy showed that the crop mucosa fell off with mucus inside, the glandular stomach was congested, and the small intestinal mucosa had bleeding spots. According to the performance of the chicken flock and the situation of the chicken farm introduced by the chicken farmers, other possibilities were basically ruled out, and the chicken salt poisoning was temporarily diagnosed. The experience of this chicken farmer reminds me of an article on the Internet advocating feeding chickens with salt. In

Broiler farming is very popular nowadays. People in many areas are raising broiler chickens. Some people are very profitable from breeding, but many others are not very profitable. Why? The conclusion is that the unreasonable feeding management has slowed down the speed of breeding and production, and the profit has become much lower. Today, I will introduce the cultivation technology of broilers. 1. Build a place of broiler production The place to build a chicken farm is very important. It is best to choose a place where the terrain is high, sunny, no pollution, no noise, and a good traffic environment. Such a place is most suitable for building a

Laying hens refer to chickens that are raised to lay eggs to supply eggs. Unlike broiler chickens, the main issue of people raising laying hens is to improve the quality of eggs and maintain or increase egg production, not to improve chicken quality. Eggs are the main source of income for raising laying hens. The technology of laying hen breeding is becoming more and more scientific. Today I will introduce how to breed laying hens in autumn and winter. 1. Always pay attention to layer weight Due to the high temperature in summer, the body weight, physique, immunity, antibody, etc. of the chickens have decreased. Feeding management in the autumn

In chicken production, especially under the conditions of intensive production, chickens have a certain strain and adaptability to the stimulation of stocking density, climate, immunization, transfer, grouping, beak cutting, light and other factors. If the intensity of these stimulations If it is too large or lasts too long, and exceeds the body's physiological tolerance, it will affect the growth, development, reproduction and disease resistance of the chicken, and even directly cause death. In the cold winter, chickens are most susceptible to cold stress, which affects the laying rate of laying hens, reduces benefits and increases costs. In order to avoid cold stress, you should be prepared and take appropriate measures.

1. How to disinfect the newly dug crayfish breeding pond? The newly excavated shrimp pond has no sediment at the bottom of the pond, and there is no need to clean the pond. After the excavation is completed, it can be treated as follows: air drying-water supply-disinfection-detoxification-planting grass-fertilization-fertilizer and hydroponic culture Bacteria-fodder fertilizer. Wait for the pond environment to get better and better, and then enter the seedling preparation. (1) After the new pond is dug, let it dry for half a month or longer to fully expose and oxidize the organic matter in the pond; (2) Drain the water after soaking for a week or more, and continue to

The recovery of everything in spring is a good season for raising pigs. However, as pigs go through a long winter, the body' s disease resistance is weakened, and various pathogens also multiply as the temperature rises. Poor management by farmers can easily cause pigs. When the disease occurs, epidemic prevention is the focus of pig raising work in spring and should be paid attention to. 1. Improve the pig house environment Provide a good growth environment for pigs Keep the pig house warm, dry and ventilated, and improve the sanitation of the pig house. The spring weather in the north is unpredictable, and the temperature difference between day and

In the process of raising pigs, it is inevitable that some diseases will be encountered. Only when the cause of the disease is correctly judged and the right medicine can be cured as soon as possible, otherwise the longer the delay, the growth and development of the pigs will be greatly affected. For farmers, in addition to judging whether the pig is sick by the appearance and mental state of the pig, it can also be judged from the feces what kind of disease the pig is sick. So what diseases can pig feces judge? Only by correctly judging the feces of pigs can we solve the problems of pig

Laying hens are 400 days old, which is the later stage of rearing, and are commonly called "old chickens". At this time, the quality of eggshells generally began to decline, the thickness and strength of the eggshells decreased, the white shells, soft shells, sand shells, thin shells, and cracked eggs increased, and the damage rate increased. The main problem is that the physiological reproductive function of "old chickens" is reduced and the reproductive organs are aging. If precise nutrition adjustment can be carried out, the physiological function can be improved, the quality of eggshells can be improved, the rate of decline of egg production can be delayed, and the egg

1. Breeding site selection and engineering construction （1）Crayfish breeding sites require adequate water sources, convenient irrigation and drainage, and strong flood and drought resistance capabilities. The pH value of the soil is neutral to slightly alkaline, and there is plenty of sunlight and long exposure time, which is conducive to the reproduction of plankton, especially leeward to the sun. In order to ensure that crayfish products meet the pollution-free requirements, the breeding site must be far away from industrial, agricultural and domestic pollution sources, and the environment must meet the pollution-free breeding standards. （2） Reinforce and heighten the ridges, and excavate shrimp trenches and shrimp pits. In order to prevent

During the breeding process of laying hens, the production and maintenance of uniform and effective antibodies such as vaccine itself, immunization method, and immunization dose have an important impact. In addition, diseases of the digestive tract, respiratory tract and reproductive tract will also be synthesized, neutralized and metabolized To affect the uniform and effective antibody production. Therefore, healthy laying hens need to do three health care tasks, namely health care of digestive tract, respiratory tract and reproductive tract. 1. Digestive tract health care The factors that affect the health of the digestive tract include the integrity of the digestive tract, acidity and alkalinity, micro-ecological environment, and soundness of development.
