Snake breeding and selection is carried out in three steps, with the specific methods explained in detail
Strengthening the artificial breeding and selection of snakes is of great significance for improving the reproductive survival rate, growth and development speed, product quality and economic benefits of snakes. It is a task that cannot be neglected in a snake farm and must be carried out year-round with persistent effort. In breeding and selection, the following three points should be done well: 1. Selection of breeding eggs. The breeding eggs placed in incubation must be fresh and of high quality. Eggs stored for a long time have a low hatching rate and a high mortality rate, and the hatchling snakes are weak and grow slowly. Therefore, the female snake should be checked frequently before laying eggs, and when the eggs are found to be approaching the cloaca,

The key to precision sowing of wheat with reduced seed rates lies in accuracy
When mechanical precision sowing with reduced seed rates is used for the three wheat crops, it can save 5 kg of seed per mu compared with conventional mechanical drilling, save 10 yuan in costs, and increase yield by 50 kg. But to truly achieve this effect, the word "precision" must be emphasized during sowing. 1. Fine seedbed preparation. The wheat field soil is required to be "deep, level, fine, and clean," with the mature soil layer reaching more than 8 cm deep, the surface level with no depressions, clods broken down until there are no "egg clods," and no exposed stubble, waste film, or other debris on the surface. Farmyard manure should be applied heavily all at once before sowing.

There's an art to feeding pigs with homemade feed: keep these three precautions in mind
Whether for family or intensive pig farming, using homemade pig feed can greatly reduce feeding costs. However, when feeding homemade pig feed, you must grasp three "precautions." Pay attention to the types and proportions of raw materials. The commonly used raw material proportions for pig feed are: grains such as corn, rice, barley, and sorghum, which should generally account for 50%-70%; bran types such as wheat bran and rice bran, which should generally account for 10%-20%; toxic cottonseed cake, meal, and rapeseed cake, etc., should be less than 10%. Animal protein feeds such as fish meal

Can Keeping Chickens, Ducks, and Geese Together with Pigs Lead to Highly Pathogenic Avian Influenza?
Poultry should not be kept together with pigs, because influenza viruses from poultry can infect pigs, and human influenza viruses can also infect pigs. Since influenza viruses have 8 different nucleic acid segments, when these two different virus particles infect a single cell together, their nucleic acid segments undergo reassortment and rearrangement to produce new types of influenza virus particles. These new influenza virus particles can often cause major epidemics in humans, resulting in great harm. In addition, chickens should not be kept together with waterfowl such as ducks and geese, because

Disinfection with chickens present is an important measure for green product production
Disinfection with chickens present is an effective measure for preventing and controlling avian influenza and Newcastle disease on large-scale chicken farms. It is especially necessary during periods with more spring winds, and for chicken houses housing flocks of different ages. The specific method of operation: choose an appropriate time. In winter, when temperatures are low, it is best to choose midday when the temperature is high, so the aerosol evaporates quickly, the chickens breathe it in quickly, absorb it quickly, and it takes effect quickly. In spring and summer, when the normal temperature is above 20°C, it is best to choose the afternoon or evening, when the temperature is constant and the aerosol evaporates slowly, so the floating disinfection time inside the house is long.

Seed dressing for cotton has many benefits; the right method gets twice the result with half the effort
Many years of practice have proven that proper seed dressing at cotton sowing time is one of the important measures to ensure full stands and strong cotton seedlings. It can economically, safely and effectively control or reduce damage from cotton seedling diseases, cotton aphids, soil pests and other diseases and pests, achieving twice the result with half the effort. Now that Qingming has passed, cotton sowing work across the city has been fully launched. This technique is briefly introduced as follows: 1. Choose disease-resistant or disease-tolerant varieties or sow coated seeds, which can advance emergence by 3 to 4 days and reduce disease incidence. 2. Use 75% phorate

Method for treating night sweats in livestock with Danggui Liuhuang Tang
Night sweats are mostly caused by yin deficiency with disturbed heat, so that the heart fluid cannot be restrained and stored. In livestock with yin deficiency and internal heat, during the day the defensive qi is firmly secured on the exterior, and even though internal heat steams the fluids, sweating cannot occur; at night the defensive qi moves into the yin division, and without the support of yang qi, the fluids cannot be stored internally, so they leak outward and become night sweats. Treatment principles: nourish yin and clear heat, restrain yin and stop sweating to secure the exterior. Prescription: Angelica sinensis (dong quai) and prepared Rehmannia each 50g, Scutellaria baicalensis and Phellodendron amurense each 40g, Coptis chinensis 30g, Astragalus membranaceus 100g, fossilized bone and oyster shell each 70g, Ephedra root and floating wheat each 80g, one dose daily; after one oral dose the sweating is greatly reduced, and after three doses the condition is cured.
