6 reasons piglets grow slowly, pig farmers should learn about them early
1. Improper weaning: Farmers often use the one-time weaning method, and the piglets are sold immediately after weaning, causing the piglets' original living conditions - centered on the mother and living together with littermates in a stable and comfortable environment - to suddenly change, making it difficult for them to adapt for a time and affecting weight gain. The number of sucklings given to piglets should be gradually reduced 5 to 6 days before weaning until weaning is complete. 2. Delayed supplementary feeding: If piglets are not given supplementary feed in time during the suckling stage, they cannot eat well after weaning, resulting in slow growth and stunted development. Generally, supplementary feeding should start when piglets are 10 days old

How to fertilize cotton reasonably? A detailed practical guide
Apply flower and boll fertilizer heavily. The flowering and boll stage is the most vigorous growth period in the entire life of cotton. Both the vegetative growth and reproductive growth of cotton reach their peaks, and nutrient demand is greatest. Timely fertilizer supplementation plays a key role in promoting cotton bolls, preventing premature senescence, setting more bolls on all three fruiting branches, and increasing boll weight. In fertilization, the cotton plants should be kept from excessive vegetative growth. For cotton fields with high fertility and vigorous plant growth, topdressing can be delayed until the full flowering stage when 1 to 2 large bolls have formed on the lower part of the plant; for cotton fields with low fertility and weak growth, flower and boll fertilizer should be applied early and heavily at the initial flowering stage. Generally, in mid-to-late July, apply urea per mu

Detailed Explanation of Key Points for Reasonable Fertilization Techniques for Cotton
Vigorously promoting scientific fertilization techniques for cotton is an important measure to increase the yield per unit area and product quality of cotton fields. The demand of cotton for the three major elements of nitrogen, phosphorus, and potassium and fertilizer application techniques. Field fertilizer efficiency test results prove that for every 100 kg of seed cotton produced, 5.0 kg of pure nitrogen, 1.8 kg of phosphorus pentoxide, and 4.0 kg of potassium oxide are required, with the ratio of nitrogen : phosphorus pentoxide : potassium oxide being 1 : 0.36 : 0.8. Reasonable application of base fertilizer. Base fertilizer should be mainly organic fertilizer, combined with a certain proportion of chemical fertilizer. Generally, per mu, use pig and cattle manure

How to reasonably choose a scientific formula for oyster mushroom cultivation?
Oyster mushrooms have low requirements for raw materials, and many industrial and agricultural by-products can be used as raw materials. However, whether the carbon-to-nitrogen ratio in the growing medium is scientific and whether the amounts of other supplementary materials added are reasonable are issues that cannot be ignored in oyster mushroom production. At present, bag-cultivated oyster mushrooms mainly use cottonseed hulls as the raw material, so the quality of the cottonseed hulls directly affects the level of oyster mushroom yield and even whether cultivation can succeed. Fresh, high-quality cottonseed hulls should be selected; if moldy and deteriorated cottonseed hulls are used, it will cause contamination by weed molds and may even lead to cultivation failure. Pesticides or other

Pigs need a reasonable water supply, and pig farmers must pay attention to it
I. The harm of insufficient drinking water for pigs. At present, in pig raising there is a widespread phenomenon of only paying attention to feeding while neglecting drinking water, not realizing that drinking water for pigs is equally important as feeding, or even more important than feeding. The main harms of insufficient drinking water are: 1. Insufficient drinking water can lead to an increased incidence of intestinal diseases in pigs. In household pig farming by farmers, most use the traditional feeding method of supplying water and feed all at once, and between meals, regardless of the weather conditions and regardless of the type of feed, no drinking water is given. Because pigs are thirsty due to insufficient drinking water, especially in hot summer, they often drink dirty water

Pigs rooting at the pen and gnawing at soil are not just mischief; the reasons behind it need to be understood
Pigs rooting at the pen and gnawing at wood and soil are not just playing around; it is an abnormal phenomenon that affects the pigs' normal growth and development. The main causes are: first, growing-finishing piglets lack the mineral feed needed for growth; lactating sows and pregnant sows use their own mineral elements for the normal growth of suckling piglets and fetuses, and the minerals in the feed are hard to meet the demand. Second, the feeding is unreasonable: too little feed is given, the pigs do not eat their fill, and no water is provided with the feed. Third, sick pigs also show pen-rooting and gnawing at wood and soil. Prevention methods: first, pay attention to the feed mixing ratio and add mineral

What are the reasons fish frequently get sick?
In aquaculture practice, a phenomenon is often observed: species with strong disease resistance in the wild become prone to disease after living in aquaculture environments for a long time. The strength of a fish's disease resistance is mainly determined by its genetic factors, but whether it ultimately becomes ill is determined by the environment. Various stimuli from the environment to fish are called environmental stress factors. In aquaculture ecosystems, the stress that fish experience is often caused by environmental factors such as non-ionized ammonia, dissolved oxygen, pH, and water temperature. Generally speaking, aquac

Why do crystal shrimp die? You need to know these few reasons
The causes of death in crystal shrimp boil down to the following types: 1. Cannibalism - often occurs when stocking density is too high; the targets of attack are usually individuals that have just finished molting, because they carry a slight fishy smell that triggers attacks from their own kind. The prevention method is to plant dense aquatic plants so the shrimp have hiding places! 2. Death from cold - water temperature that is too low will affect the activity level of crystal shrimp; their limit is 10°C, and below 10°C it will cause death! 3. Attacks by planarians - planarians in the tank pose a threat to crystal shrimp, especially

Reasons Why Azaleas Die and How to Prevent and Treat Them
Azaleas suffer from many common diseases and pests. Having grown flowers for many years, the author has summed up eight causes from practical experience. 1. Diseases. Black spot is the main disease of azaleas, with outbreaks being more serious from June to August, and most severe when the temperature is between 25°C and 32°C. When the temperature is below 10°C, the disease can stop spreading. After infection, black spots form on the leaves, which gradually dry up and fall off. This is the main cause of azalea death. Prevention and treatment: 1. Burn the diseased leaves. 2. Chemical control. ① Spray the leaves with a 600-800 times dilution of 50% wettable carbendazim or tuijunte

Reasonable spraying of brassin with Shuofeng 481 on cotton gives good results
Shuofeng 481 is a brassinolide product extracted from plant pollen and its derivatives. It comes from plants and acts on plants, with functions such as promoting cell division and elongation, promoting photosynthesis, delaying senescence and improving stress resistance, and combines multiple effects of auxin, gibberellin and cytokinin. Cotton is a crop with a relatively long growth period, and its growing season goes through a process from low temperature to high temperature and then to low temperature, and from high humidity to drought. Reasonably spraying brassin Shuofeng 481 throughout the whole growth period of cotton promotes cotton growth and improves its
