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

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.

Practical technical points for heatstroke prevention and cooling in summer chicken raising
The most suitable temperature for laying hen production is 17°C to 28°C, and the temperature range with little effect on production is roughly 7°C to 27°C. When summer temperatures in Shandong generally exceed 35°C, chickens will faint, and when they reach 40°C, chickens will die. Experiments have shown that when the temperature inside the chicken house reaches above 30°C, rooster sperm decreases, hen sexual maturity is delayed, the fertilization rate drops by 60%, and laying by laying hens generally declines. At the same time, due to a drop in blood calcium and an imbalance in acid-base balance, other diseases are easily induced, such as E. coli and mycoplasma disease. Because broiler chickens are large in body size, prone to fat

Four-spored mushroom cultivation in summer is difficult, but mastering the techniques brings high returns
Summer cultivation of the four-spored mushroom (Agaricus bisporus) is more difficult than that of the common button mushroom. If cultivation techniques are careless, or if the temperature during the fruiting period is too high or too low, failure will result. The high-yield secrets for summer cultivation of the four-spored mushroom are described below: 1. Plant early at the right time. Planting too early means low temperatures in the early stage, which is unfavorable for the growth of summer mushroom mycelium; planting too late means that timely feeding for the autumn mushroom will shorten the harvesting period of the summer mushroom. Therefore, after cleaning the spring mushroom growing room in late April, the summer mushroom compost can be pre-wetted and stacked. 2. Compost fermentation. 1. Compost formula (calculated for 110 sq m). Rice straw 2000 kg, gypsum 7

Understanding High-Fever Diseases in Pigs in Summer and Autumn in One Article
For the pig industry, summer and autumn can span from May to early November each year. Over this half-year period, pig diseases are commonly seen and frequently occur for many reasons. According to rough statistics, the incidence of pig diseases in summer and autumn accounts for about 70% of the whole year. The notable feature of pig diseases during this period is that clinically they are mainly characterized by high fever, with body temperature mostly rising above 41°C, presenting as continued fever or recurrent high fever. Among the commonly occurring high-fever diseases are: swine fever, swine erysipelas, swine pasteurellosis, piglet paratyphoid, swine septicemic streptococcosis

How to manage cherry blossoms in summer? A detailed guide to care methods
1. Mulching with straw to prevent drought. In summer, temperatures are high and evaporation is fast, so the amount of watering is greater than in other seasons, but the principle of "do not water if not dry, and water thoroughly when you do" should still be followed. Cherry blossoms are shallow-rooted plants, and their growing roots are close to the soil surface and dry out easily. Straw can be used to cover the base of the tree, which not only retains moisture and resists drought, but also prevents the cherry tree's fine roots from being washed out and exposed, while greatly reducing evaporation of soil moisture. 2. Wrapping the trunk to prevent drought. Within 2 to 3 years after planting, to prevent the trunk from drying out, it can be wrapped with straw. Because the bark of cherry trees is relatively thin, wrapping the bark can prevent

What harm does excessively high temperature in a snake enclosure in summer do to snakes?
In captive snake breeding, whether in indoor housing or outdoor snake enclosures, the stocking density is generally quite high. In summer, if the temperature inside the snake enclosure is too high, or before and after heavy rain when high temperature and high humidity with poor ventilation easily occur, the snakes being kept will refuse to eat, become inactive, and fail to shed their skin; some may even adopt a passive heat-avoidance strategy and enter "summer dormancy," which will inevitably affect their normal growth and development. Because snakes themselves have no sweat glands, they cannot regulate their own temperature and humidity. When the temperature inside the enclosure approaches 30°C, the snakes' water intake will increase, their breathing will speed up, they will become listless, and their activity will become irregular; in severe cases they will vomit mucus and phlegm (caused by pneumonia), which can lead to death. Diseases contracted by snakes in this season are often highly contagious and tend to cause relatively large economic losses, so medication should be administered promptly for treatment.

Key Points for Summer Management of Scorpions, a Must-Read for Breeders
In southern China, summer lasts a long time, and in July to August the temperature is often above 30°C, while the relative humidity of the air is often around 85%-90%. In such a hot and humid season, the management of scorpions cannot be neglected. The summer management measures for scorpions are described below. 1. Increase the amount of feed supplied. When the temperature is above 25°C, scorpions become more active as the temperature rises, and their food intake also increases. At this time, they are also in a vigorous period of growth and development, with high consumption, and their bodies need a large amount of nutrition and water

Rabbits Are Prone to Heatstroke in the Hot Summer, Rabbit Farmers Must Not Forget Prevention
Heatstroke is a common disease of domestic rabbits in summer, and simply because rabbit farmers often take it lightly, cases of rabbits dying from heatstroke are frequently seen. Therefore, as the hot summer arrives, rabbit farmers are especially reminded never to forget to guard against heatstroke in rabbits. Precautions: set up simple shade shelters around the rabbit hutch or spread shade netting. Open all doors and windows of the hutch to let the air circulate; splash well water on the walls and floor inside the hutch to cool it down; provide the rabbits with plenty of clean drinking water, and feed more fresh green forage and an appropriate amount of watermelon rind, cucumber peel, etc., to help the rabbits quench their thirst and prevent heatstroke.

Cyanobacteria in mussel ponds tend to overproliferate in midsummer; pay attention to prevention and control
Summer has high water temperatures and strong light, making it a season of high cyanobacteria incidence. Once cyanobacteria proliferate heavily on the water surface, the water quality becomes lean; after pearl mussels ingest cyanobacteria, it is not easy for them to digest (cyanobacteria have thick cell walls), and cyanobacteria adhere to the mussels' gills, affecting respiration. At the same time, after cyanobacteria die, protein decomposition produces hydroxylamine, which combines with toxic substances such as hydrogen sulfide in the water and can poison the pearl-culturing mussels to death. Therefore, in summer, the excessive proliferation of cyanobacteria must be strictly controlled, with targeted prevention and treatment. 1. Summer temperatures are high, and at the bottom
