To raise pigs well, feed formulation is the key
First, it must be varied and reasonable to ensure comprehensive nutrition. Among the three types of feed for pigs - green feed, roughage and concentrate - green feed contains more water, is bulky, easy to digest and highly palatable, and contains a variety of vitamins, minerals and protein; roughage is bulky and has a relatively high crude fiber content, and when reasonably combined it can increase the contact surface between feed and digestive juices and has a laxative effect, easily giving pigs a feeling of fullness, but it is difficult to digest; concentrate is characterized by small volume, high nutritional value and easy digestion, but is relatively lacking in minerals and vitamins. Second, pay attention

What causes deformed oyster mushrooms?
The occurrence of deformed oyster mushrooms should be largely related to the large temperature difference between day and night. Since the arrival of winter, temperatures have remained low. In order to make oyster mushrooms grow quickly, many mushroom growers deliberately raise the greenhouse temperature during the day. Generally, after about three o'clock in the afternoon, because ventilation continues, the temperature inside the greenhouse begins to drop rapidly. Since most of the mushroom greenhouses currently used are relatively simple and have poor insulation, at night the temperature can drop to 4-5°C or even lower. Because the temperature is low and the substrate temperature is low, the mycelium's ability to transport nutrients is very poor. When the daytime temperature is briefly higher,

How to prevent deformity in winter oyster mushrooms? These measures must be mastered
1. Blue mushroom: During the growth of the fruiting body, a blue halo forms at the edge of the cap, and even the entire fruiting body turns blue-black, without fading until harvest. Preventive measures: For warming measures, methods such as sunlight, heating, and electric heating are preferable. If burning wood or coal is used for warming, closed heat-transfer and smoke-exhaust pipes should be installed, and it is not advisable to build a stove directly in the mushroom house. 2. Big-foot mushroom: After the primordium forms, the differentiation and development speed of the cap is inconsistent, showing only the stipe growing, thick at the bottom and thin at the top, with no mushroom umbrella growing, and the cap

How to prevent deformities in oyster mushroom cultivation in winter?
After the primordia of thick-stemmed mushrooms appear, the differentiation and development speed of the cap is abnormal, manifesting as a small cap, a long stem, and a thick, hard stem, with relatively low commercial value. The main cause is the use of closed insulation and cold protection measures, which leads to insufficient oxygen supply and loss of balance in nutrient transport within the mushroom body. Preventive measures: during continuous low-temperature weather, when the mushroom greenhouse adopts closed insulation and cold protection, attention should be paid to short periods of ventilation at noon, but avoid strong winds blowing directly on the substrate surface, to prevent young mushrooms from dying. Blue mushroom: when the mushroom body grows, a blue halo appears on the edge of the cap,

Why should dog sterilization surgery be performed as early as possible?
Dogs generally reach sexual maturity at around 8 months after birth. Female dogs experience their first estrus at this time, and thereafter it occurs twice a year, which is known as the "heat period," the time when pregnancy is possible. On the other hand, after male dogs reach sexual maturity, in order to induce the arrival of the female dog's "heat period," they display a series of behaviors pursuing female dogs. For example, barking, going to places where there are female dogs, fighting with other male dogs over female dogs, and so on. In short, it is very difficult for them to settle down.

What causes secondary branching and deformed scapes in garlic? Here's how to prevent it
Every year during the scape-elongation stage of garlic, a certain proportion of garlic plants develop secondary branching and deformed scapes, seriously affecting the yield and quality of garlic scapes. In recent years, we have carried out investigations and research, and have explored effective agricultural measures to control the occurrence of secondary branching and deformed scapes in garlic, which have played a very significant role in improving the economic benefits of garlic growers. 1 The harm caused by secondary branching and deformed scapes in garlic. Secondary branching in garlic is also called secondary growth or branching, and growers call it "horsetail garlic". There are generally two phenomena: first, branches differentiate from the outer leaf sheath,
