Analysis of Key Points in Winter Management Techniques for Live pigs
The arrival of winter brings some problems to pig farm management. Diarrhea has become an unavoidable and most headache-inducing problem on pig farms, and insulation work will become one of the most important tasks in pig farm management. But before many pig farms have fully solved the diarrhea problem in pigs, respiratory problems in pigs quietly arrive. Like diarrhea in pigs, in recent years pig respiratory diseases have become a very headache-inducing problem on pig farms, bringing major economic losses to the pig industry. Properly handling the issues of warmth and ventilation in pig farms is directly related to controlling diarrhea and respiratory syndrome, and is

Beware of Vitamin B Deficiency in Pigs in Winter
Symptoms: When vitamin B2 (riboflavin) is deficient, sick pigs grow slowly, vomit, develop skin rashes, and lose hair, etc. When vitamin B3 (pantothenic acid) is deficient, sick pigs have poor appetite, poor growth, diarrhea, coughing, hair loss, and poor coordination, especially showing a "goose-step" gait. When vitamin PP (niacin) is deficient, sick pigs completely lose appetite, become emaciated, have severe diarrhea, cracked skin covered with black scabs, nervous disorders, and anemia. Prevention and treatment: When preparing pig rations, pay attention to fully supplying bran and green

Why should sheep drink enough warm water in winter and spring?
In winter and spring, because the temperature is relatively low, if sheep are given cold water or even water with ice particles, they are unwilling to drink it, which will cause insufficient water intake. This not only slows down the digestion of sheep feed, blocks metabolism in the body, and reduces body condition, but also causes various diseases. Therefore, in production, drinking water conditions must be created for sheep to ensure clean and sufficient drinking water. Drinking water temperature: if the water the sheep drink is too low in temperature, the water will absorb the heat that the sheep itself converts from feed, which will reduce feed utilization. Therefore, in winter and spring, the best drinking water temperature for sheep is 20-30°C

Detailed Explanation of the Intercropping Model of Honeysuckle and Medicinal Herbs
Intercropping Model of Honeysuckle and Medicinal Herbs Honeysuckle is a commonly used bulk medicinal herb with wide uses and high value. It can be cultivated throughout the country. However, due to its long growth cycle and inconspicuous short-term benefits, people are deterred despite knowing that planting honeysuckle is profitable and can lead to prosperity. Now, based on the growth characteristics of honeysuckle, an efficient intercropping model of expanding rows, reducing plant spacing, rational close planting, intercropping medicinal herbs, and using "medicinal herbs" to nourish "flowers" has been adopted, achieving the goal of "planting flowers in the same year, seeing results in the same year," providing an effective path for the large-scale and modern development of honeysuckle.

Detailed Explanation of the Key Points of Winter Pruning Techniques for Honeysuckle (Japanese Honeysuckle)
Winter pruning mainly involves cutting off the branches that grow from the main trunk, and selecting and keeping a small number of mother branches on the main branches that can flower the following year. For young plants, select 4-5 robust branches on the main branches and cut off the upper ends at 3-7cm. Winter pruning can only be delayed, not advanced. Pruning of adult trees is mainly carried out in winter. In addition to mastering the essentials of removing the weak and keeping the strong, removing the curved and keeping the straight, and thinning out the overlapping ones, the number of mother branches should also be determined according to water and fertilizer conditions. After pruning, apply fertilizer once and water thoroughly with freezing water.

How to safely overwinter shiitake mushrooms through summer? These management points must be mastered
The quality of summer management for shiitake mushrooms directly affects yield and profitability. Doing a good job of summer management is a key step in shiitake mushroom production, and two methods can be used: indoor and outdoor. I. Indoor spawn running for summer survival (1) Minimize the number of shiitake bags indoors and the number of bag layers. Stack two bags in a cross pattern, with no more than 5 layers at most, and keep the spacing between stacks at more than 20 cm to facilitate ventilation and heat dissipation. (2) Build a shade canopy outside the window so that sunlight does not shine directly onto the window or indoors. (3) In hot weather, close doors and windows at 7 a.m. to prevent outside hot air from entering indoors, and in the evening

Control Recommendations for the Overwintering Generation of the Box Tree Pyralid Moth
The box tree pyralid moth (Glyphodes perspectalis) is one of the important leaf-eating pests of forestry plants in this district, mainly damaging Chinese box (Buxus sinica var. parvifolia) and Japanese box (Buxus bodinieri). Since early spring this year, the whole district has carried out 2-3 rounds of comprehensive control against this pest, effectively bringing the damage under control; however, since the damage period of this pest is long and can last until the end of October, continued follow-up monitoring of this pest is still needed. According to monitoring at two sites, the Anting Ginkgo Garden and the Fangtai Flowers and Plants Horticultural Farm, a moth peak appeared under the forecasting lamp in early to mid-September, with the highest moth numbers on September 7-9, averaging 22.3 moths per lamp per day

Detailed Explanation of the Winter Trunk-Cutting Planting Method for Black Locust
Planting black locust by trunk cutting in late autumn and early winter has several major advantages: First, it avoids the spring tree-planting peak and the busy farming season, making full use of the winter slack period, so that planting time and quality are fully guaranteed. Second, according to the physiological characteristics of black locust, the average daily temperature required for root growth is relatively low; after leaf fall in autumn the above-ground part stops growing while the underground part continues to grow for a period, and when the leaves fall the mobile nutrients in the branches and leaves return to the trunk and roots, at which time the roots are rich in stored nutrients, which precisely gives the root system a stage for growth. Third, the plots where black locust is planted are generally

Feeding and management methods for autumn lambs to safely overwinter
Sheep estrus and mating occur mainly in spring and autumn, and the gestation period averages around 150 days, so spring and autumn are also the seasons when lambing is more concentrated. According to surveys, the overwintering survival rate of autumn lambs born in various places is significantly lower than that of spring lambs. The main reasons: 1. Environment. When autumn lambs overwinter, they are in the suckling period or weaning period. In winter, green fodder is scarce, forage quality is poor, ewes' milk is insufficient, and lambs are malnourished, weak in constitution, and poor in disease resistance. Moreover, the long dry and cold winter climate very easily causes respiratory infections in lambs, and many lambs die from pneumonia infection. Due to the cold climate

Sarcoptic mange in pigs is common in winter, pig farmers should take preventive measures
Sarcoptic mange in pigs, also called scabies, commonly known as mange, is caused by Sarcoptes scabiei mites parasitizing in the pig's skin, causing skin lesions such as red spots, pustules, crusts and fissures. It is characterized by intense itching, restlessness, reduced appetite, slow growth and decreased feed conversion, and is one of the diseases that seriously harm pig production. It is widespread in some farms and difficult to cure. The severity of its clinical symptoms is related to the pig's resistance. When climatic conditions are suitable and feeding management is good, the pig's resistance is strong and there are generally no obvious symptoms. In the high-temperature summer season, frequently washing the pig pens and pig bodies helps
