Matters needing attention in Pig Immunization
Pig farmers vaccinate pigs once, twice or more times every year, but pigs still have immunized infectious diseases, resulting in great losses. What's the reason? This has a lot to do with the matters needing attention that do not pay attention to immunization. As a result, we give a reminder to the vast number of pig farmers. First, pay attention to buying vaccines from reliable departments. Vaccines or vaccines need to be managed in a special way so that they do not fail. Before purchasing a vaccine or vaccine, it is necessary to confirm whether the department that sells the vaccine has a certain technical strength to ensure the epidemic.

How to prevent and cure swine pox
The disease is an acute and febrile infectious disease caused by swine pox virus. Acne rash occurs on the mucous membrane of some parts of the skin. When the weather is cloudy and rainy and cold, the pigsty is damp and filthy and pigs are malnourished, the epidemic is serious, and the morbidity and fatality rate are high. It often occurs in piglets of 4-6 weeks old. During the onset of the disease, the body temperature of the diseased pig increased by more than 41 ℃ and did not eat. The inflamed eyelids were stuck by secretions, the nostrils were runny or blocked, and erythema appeared in the sparse parts of the body, such as the nasal disc, eyelids, medial thigh, lower abdomen, etc.

Occurrence and integrated control of sheep nose fly
Sheep nose fly is a disease caused by sheep nose fly larvae parasitic in the nasal cavity of sheep, which mainly harms sheep. The adults of sheep nose flies produce larvae directly, and the larvae change into adults by pupa. The adult sheep nose fly appears from May to September every year. After mating between male and female, the male fly dies and the female flies perch. After the larvae in the body develop, they fly and breed maggots and larvae in the nostrils of sheep. The first stage larvae attached to the nasal mucosa of sheep, and gradually migrated intranasally, until they degenerated into the second stage larvae in the nasal cavity and frontal sinus, and developed into mature third stage larvae in the spring of the second year.

Treatment of cold diarrhea in pigs
Cold diarrhea in pigs has been confirmed to be caused by transmissible gastroenteritis and epidemic diarrhea in pigs, which is easy to get in cold weather. Once pigs get this disease, in addition to severe diarrhea and death of pigs (the mortality rate of suckling pigs can be up to 100%), it also seriously affects the growth of pigs and increases the elimination rate of pigs. In order to effectively control the occurrence of the disease, the pathological features and control measures of the disease are introduced as follows: pathological characteristics of gastroenteritis and gastroenteritis in pigs

Two Key Control Chains in Porcine Artificial Fertilization
In recent years, pig artificial insemination technology has developed rapidly, large-scale pig farms have basically carried out artificial insemination work, and there have been some large-scale boar breeding stations (companies) mainly selling boar semen, mainly including SPF boar breeding stations in the northern region of the Ministry of Agriculture affiliated to Beijing Pig Breeding Center and Beijing Haobang Pig Artificial Insemination Service Co., Ltd. At the same time, in rural areas where individual pig farmers are concentrated, small boar stations with 3 to 5 boars invested by individual farmers appear like bamboo shoots. The author concludes in

Causes and prevention methods of chicken pecking jar
First, the reason is that the feeding density is too high. The feeding density is too high, the trough and material trough are insufficient, and the chickens compete for water, so that some chickens are lack of nutrition and are prone to pecking. 2. Improper environmental regulation of chicken house. If the air in the henhouse is dirty and the harmful gas exceeds the standard, the chickens will be restless and pecker; the temperature is uneven, cold and hot, which will cause great stress to the chickens. 3. Dietary nutrition is unreasonable. Chickens should not have insufficient animal protein or amino acid imbalance in the diet.

Technical essentials of lamb delivery in spring
February to March every year is the peak lambing season for sheep. To give birth to ewes, it is necessary to master four main points: first, prenatal preparation. At this time, the weather is warm and cold, ewes should prepare the delivery room before lambing, keep the temperature above 5 ℃, and disinfect it with 2% Murray, 4% laisu water or 15% Murray 20% plant ash water. Cover the floor of the delivery room with hay or sand to keep it dry. At the same time, some disinfectants (such as alcohol, iodine tincture, etc.) and other tools should be prepared appropriately.

Key points of cultivation techniques of Abrus cantoniensis
The adaptability of chicken bone grass is strong, the soil requirements are not strict, general dry land (flat land, sloping land) can be planted, sandy loam is good, drought resistance, fear of waterlogging, planting land to be well drained, sufficient sunshine. 1, seedling (solar calendar 3~4 months sowing is appropriate), chicken bone grass seed coat smooth and hard, must be treated before sowing, otherwise the germination rate is not high. Treatment method: Mix the seeds with twice the amount of fine sand, put them in mortar holes or bamboo tubes, pound them with round-headed wood for 20 minutes, or rub them with hands for 30 minutes, and sift out the sand.

Insert esophagus or trachea to inject drugs into pigs and be careful.
Pigs often lose their appetite and even do not eat when they get sick, which makes it difficult for artificial forced drug administration. So, how can we solve this problem? First of all, hold the sick pig and make it stand or lie on its back. Then, use the mouth opener to pry open the pig's mouth and quickly insert the gastric tube into the esophagus along the tongue surface through the root of the tongue. When the position of the inserted gastric tube is correct, the pre-dissolved drug can be injected, and then a small amount of gas is filled into the tube after filling, so that the drug in the gastric tube is emptied. Finally, pull out the stomach tube quickly. Special attention is required.

Concentrate feed should be matched with green roughage, and an appropriate amount of minerals and trace elements should be added, such as adding 1% 2% bone meal and 0.25% 0.5% salt, which has a certain effect on preventing pig molars at night. Once the phenomenon of grinding teeth at night occurs in pigs, each pig is fed with bone meal or eggshell powder, calcium bicarbonate powder 30g, salt 6g, and salt 7g every day.

Other effects of feed on egg quality
Egg weight is affected to some extent by dietary protein levels. Increasing dietary protein levels, especially animal protein levels, contributes to increased egg weight. Some trace elements are related to the internal quality of eggs. Dietary supplementation of iron, copper, zinc and selenium can improve the internal quality of eggs. If the feed is contaminated with pesticides or heavy metal toxins, it will also affect the quality of eggs.
