Diagnosis and treatment of pig distiller's grains poisoning
Pig lees poisoning is often caused by lack of other feed combinations due to long-term feeding of lees, or sudden feeding of a large number of lees or moldy lees. The toxic components of distiller's grains are alcohol remaining in distillers' grains, and organic acids and fusel oils produced by continuous fermentation and rancidity of distillers' grains, such as acetic acid, n-propanol, isobutanol and so on. 1. Clinical symptoms 6 35kg~45kg fattening pigs raised by a farmer showed poisoning symptoms after eating wine trough, and one of them died. At the initial stage of poisoning, the feed intake of pigs dropped sharply.

Why do piglets grow slowly?
Some farmers reflect that the piglets raised at home grow very slowly. What on earth is the reason? According to the analysis, there are the following reasons. 1. Unreasonable weaning farmers adopt one more weaning method to raise pigs, and immediately after weaning, the piglets' original maternal-centered, cohabiting, stable and comfortable living conditions of piglets have suddenly changed, which is difficult to adapt and affect weight gain. The times of lactation of piglets should be gradually reduced within 5-6 days before weaning until they are completely weaned. 2. the feeding is not timely and the piglets are breastfeeding.

There are 10 dietary taboos for pigs after taking medicine.
1. Mung beans: mung beans can be used as antidotes and antidotes. Pigs should be fasted after taking medicine. 2. Sorghum: sorghum contains tannic acid, which has a strong convergence effect, which is prohibited when pigs take laxatives; in addition, tannic acid can denature iron preparations and cannot be eaten in the treatment of iron deficiency anemia. 3. Soybeans and bean cakes: because soybeans contain calcium, magnesium, iron and other minerals, such as taking tetracycline drugs (such as tetracycline, oxytetracycline, etc.) and feeding bean cakes at the same time, they can form water-insoluble complexes and reduce the curative effect, so they should be banned.

The layout of goose farm is exquisite.
1. Site selection. The site is close to the water source, the water surface is as wide as possible, the water depth is 1-2 meters, the water quality is good, far away from the residential area; the soil quality is preferably sandy loam, the transportation is convenient, the direction faces south. 2. The scale is determined. The production scale is determined by investment capacity, feeding conditions, technical strength, source of goose seedlings and product sales, etc. Only by forming mass production can there be greater feeding benefit. 3. Overall planning. First of all, the housing should be divided into production areas and administrative areas, living areas, more than 50 meters apart between the two areas, separated by walls.

Prevention of osteomalacia in pregnant sheep in winter
At present, dairy goats have entered the pregnant winter period. In these years, many farmers lack the knowledge of ewes 'reproductive health care and do not realize the importance of preventing and controlling osteomalacia of pregnant sheep to ensure safe childbirth, resulting in dystocia and postpartum paralysis. Therefore, pregnant sheep osteomalacia should be prevented in winter. Pregnant sheep osteomalacia, is the lack of vitamin D and calcium phosphorus in the body. Pregnant sheep not only need their own nutrition, but also to supply the growth and development of the lambs of the material, so pregnant sheep feed to maintain a different rich nutrition.

Feed formula for pigs during lactation
Sows need a lot of nutrients to satisfy lactation during lactation. During the peak period of lactation, the lactation ability of sows was higher than that of feed intake and less than that of nutrients excluded from milk, and the body condition of sows decreased rapidly. Feeding lactating sows with high quality and high nutrient concentration feed is the best way to solve this contradiction. Feed formula 1: lactation feed formula 1 in Table 4-3 avoids the use of large solvent feed such as alfalfa, bran, etc. In the formula design of lactation feed, the unknown factor of nutrition is not very important, and this formula uses high energy as far as possible.

Breeding of introduced Pig breeds and Application of New breeding techniques
The continuous development and progress of science and technology make it possible for people to explore the laws of nature and reveal biodiversity. The greatest progress of pig breeding in the 20th century is that the daily gain of pigs exceeded 800g / day, the lean meat rate reached more than 60%, the ratio of feed to meat reached 2.8g / ∶ 1, and the body weight of pigs reached more than 90kg in 156days. In recent years, with the continuous development of breeding theory and practice, pig breeding in developed countries has gradually changed from breed selection to specialized breeding.

Why do pigs grind their teeth at night?
First, the feed is single, it is best to feed the pig with nutritious compound feed at full price. Concentrate feed should be matched with green roughage, and appropriate amount of minerals and trace elements should be added. Adding 1%-2% mineral feed to pig diet, such as bone meal, calcium hydrogen phosphate, eggshell powder, etc., and adding 0.25%-0.5% salt, etc., has a certain effect on preventing pig tooth grinding at night. The phenomenon of tooth grinding at night can be eliminated by supplying bone meal or eggshell powder, calcium bicarbonate powder 30g to 50g and salt 6g to 19g in the feed of each pig every day for 7 days.

Diagnosis and treatment of Porcine Neurological symptom Blight
Pig raising often encounters the occurrence of pig disease with "dyspnea" as the main symptom. There are 6 kinds of epidemic diseases that show "dyspnea" symptoms, which are easy to be confused in clinic, resulting in misdiagnosis. Especially for pig farms, households or rural veterinarians who lack laboratory conditions, clinical differential diagnosis is particularly important. 1. The pathogen of swine edema disease is septic Escherichia coli. It is easy to occur under stress conditions such as temperature change, weaning and refeeding, and most of them are pigs that eat more and grow faster than those who eat more than 20kg of 30kg after weaning. Sick pigs show low body temperature, agitation, walking blindly and turning in circles.

Five methods for prevention and treatment of metamorphosis in sows
In pig production, the phenomenon of low litter birth rate of sows is often encountered. In addition to the low fertilization rate, the early death of embryos caused by fertilized eggs in the process of development and absorption by sows (commonly known as metamorphosis) is also an important reason. This problem can be solved by the following methods. 1. Strengthen the feeding and management of Konghuai sows, increase protein feed and energy feed 3-14 days before breeding, and add minerals and vitamins at the same time, so that they can quickly enter the best state of mating; for the poor fat sows, the one that can be longer before mating
