Things to note when raising piglets in spring and summer, farmers should grasp them in advance
First, pay attention to temperature changes. In spring and summer, temperatures vary greatly, there is a lot of rain, and humidity is relatively high. Pigs prefer a dry environment, have little fat tissue, and piglets are prone to feeling cold. Therefore, the temperature inside the shed and the dry environment of the pen should be maintained. Second, pay attention to increasing protein feed. Especially for piglets that have undergone long-distance transport, due to stimulation such as wind-cold and the bumping of vehicles and boats, some piglets develop dysentery and diarrhea, reduced appetite, and weight loss. In addition to doing a good job of keeping the pen dry and warm, nutrition should also be supplemented in a timely manner.

Technical key points for raising growing pigs well in summer and autumn
Piglets are weaned at 3-6 weeks of age and kept in the nursery house for 4 weeks. When body weight is 20-50 kg, because bone and muscle growth is relatively fast, they are called growing pigs. At this stage, the protein level is 16% and the lysine content is 0.8%. At 50-110 kg, adipose tissue is deposited in large amounts, so the protein and lysine levels can be appropriately reduced to 14% and 0.65% respectively. Ordinary pig farmers are accustomed to using concentrate or premix combined with corn, bran and other raw materials for feeding, but attention should be paid to the fact that the premix produced by some manufacturers is not up to standard, resulting in pigs

What are the prevention and treatment methods for heatstroke in pigs in summer
As the global climate warms, summer temperatures rise year by year, and pigs with poorer heat dissipation capacity are more prone to heatstroke. Farmers should take measures to prevent and treat heatstroke in pigs. Clinical symptoms: sudden onset, sharp rise in body temperature, rapid and difficult breathing, highly depressed spirits, weakness of the limbs, ataxia, and profuse sweating over the whole body. If treatment is not timely or is unreasonable, the animal lies down and cannot rise, and dies from spasms or coma. Prevention: 1. The pig house must have good ventilation, and a shed should be built for shade to prevent direct

How to care for tulips in summer? Detailed explanation of care points
The flowering period of tulips is from March to May each year. After tulips bloom, the new bulbs in the underground part develop rapidly, and the mother bulb that served as the planting bulb disappears. Therefore, after tulips fade, the flower stems should be cut off immediately, and the leafy bulbs should be planted in pots (they can also be planted in the ground). When planting, base fertilizer should be added first, preferably soybean cake crumbs and bone meal, to promote the growth of the small bulbs that have split off. The new bulbs develop from the lateral buds in the leaf axils of the fleshy scale leaves of the mother bulb. After the terminal bud of the mother bulb forms a flower bud, the lateral buds sprout. During the period of promoting the sprouting of the lateral buds, thin fertilizer should also be applied two

Land preparation and sowing methods for spring sesame and summer sesame
Spring sesame should adopt the "plowed furrow slice" method. The so-called "plowed furrow slice" means that after the previous crop is harvested, fertilizer is applied, the soil is plowed and harrowed, and then sesame is sown. The advantages of "plowed furrow slice" are: it can turn the soil and loosen it, increasing soil temperature; bury the base fertilizer, improving fertilizer efficiency; reduce weeds, making intertillage convenient; and the soil has good aeration, which can improve the soil's water storage and fertilizer retention capacity. Therefore, planting "plowed furrow slice" sesame is a key measure for increasing yield. For summer sesame, "iron stubble" sowing should be advocated, with rough sowing and careful management. "Iron stubble" sowing means that after the previous wheat crop is harvested, there is no further plowing, plowing or harrowing; as long as it is raked

Techniques for rearing summer fry fish: stock one main fish species, do not introduce carp, and combine feed with fertiliser for intensive feeding
Summer fry fish are small and delicate, with a weak ability to withstand adverse environments. In addition, at this stage the summer fry undergo a dietary transition, and their digestive system structure and function are not yet fully developed, so their digestive capacity is poor. If rearing methods are improper, mass mortality will occur. Through experiments, the author found that adopting the following rearing methods can significantly increase the survival rate and rearing efficiency of summer fry. Scientific stocking and rational matching: the traditional rearing method is mainly polyculture of multiple species. However, from production practice, because fish have different feeding habits, this kind of rearing

How to feed silkworms well in summer and autumn? All the nutritional formulas are here
The main feed for silkworms is mulberry leaves. Because the quality of mulberry leaves varies greatly from season to season, it has a considerable impact on cocoon yield and quality. If nutritional supplements are fed to summer and autumn silkworms, the yield can be increased by 10%-20%. The formula techniques are introduced as follows: 1. Additive formulas and feeding methods. (1) Glucose solution additive. During the silkworm rearing period, if there is continuous rainy weather, the mulberry leaves are tender in texture due to insufficient sunlight, high in moisture content, and low in carbohydrates. At this time, a 5% glucose solution can be sprayed on the harvested mulberry leaves, and after they are air-dried, they can be fed to the silkworms, which can

Six Key Prevention Techniques for Introducing Straw Mushrooms in Midsummer
Straw mushroom, also known as orchid mushroom, is one of the more commonly cultivated mushroom varieties in China. Straw mushroom contains Vc and a variety of amino acids, is rich in nutrients, and has a unique flavor; it is a variety with a short production cycle, quick results, low investment, and high returns. In the hot summer, fresh mushroom varieties are already rare on the market, but straw mushroom can not only regulate the supply of mushrooms during the off-season and meet people's growing living needs, but can also generate foreign exchange through export after deep processing. Straw mushroom is a saprophytic fungus, and it must absorb ready-made nutrients and water from dead plant matter and soil in order to live.

Chemical weed control in summer sesame fields should be carried out at the right time
The seedling stage of summer sesame coincides with the hot, rainy season. The roots are few and the growth is weak, while weeds emerge quickly, are dense, and grow vigorously, easily shading the sesame seedlings and causing a weed infestation. Corresponding herbicides should be selected for chemical control at different stages. 1. Soil closure treatment after sowing but before emergence. After sowing sesame, use 100 ml of 50% acetochlor emulsifiable concentrate or 200 ml of Dual (72% metolachlor emulsifiable concentrate) per mu, add 50 kg of water, and spray evenly. This can control foxtail grass, crabgrass, shortawn foxtail, goosegrass, and many other annual grass weeds, and also has a certain control effect on many broadleaf weeds propagated by small seeds.

Key Points and Methods of Fertilization Techniques for Summer Sesame
To achieve higher yields of summer sesame, nitrogen, phosphorus, and potassium fertilizers need to be applied skillfully at the right time. When fertilizing, attention should be paid to mastering the principles of one steady, two precise, and three heavy. One steady means fertilization at the seedling stage should be steady. Summer sesame grows slowly at the seedling stage, and the root's ability to absorb nutrients is weak. If the base fertilizer is insufficient, it will cause the seedlings to be thin and weak. The seedling-promoting fertilizer should be topdressed as early as possible, but the amount of fertilizer used should be small, otherwise it is very easy to cause leggy seedlings. Two precise means topdressing at the bud stage should be precise. From the bud stage to the early flowering stage of summer sesame, the growth rate noticeably accelerates. If topdressing is timely at this time, it can promote flower bud differentiation and increase
