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

Force-feeding methods and technical key points for meat-type squab
Meat-type squab at 18 to 25 days of age can reach a body weight of 350 to 500 g, and depending on the situation can be considered ready for market. However, at this time the squab meat has a relatively high water content and little subcutaneous fat. To improve the quality of the pigeon meat, force-fattening can be carried out for 5 to 7 days before sale. After force-fattening, the squab is crisp-skinned, tender-boned and flavorful after cooking. 1 Squab selection: Squab from 10 to 25 days of age can all be force-fattened. Most often, squab at 15 to 20 days of age with a body weight of 350 to 500 g are used for fattening

Feed Formulation and Processing Techniques for Medicinal Silkworm Larvae Infected with Beauveria bassiana
Currently, medicinal silkworm larvae infected with Beauveria bassiana are in strong demand on the Chinese medicinal herb market, and raising and processing them is profitable. The methods for raising and processing them are: 1. Rearing the mature silkworms. Raising and processing medicinal silkworm larvae infected with Beauveria bassiana should be carried out as a specialized operation in non-cocoon-producing areas, so as to avoid a devastating impact on cocoon silkworms. The raising and processing can be carried out throughout the year. As for the feed, besides a small amount of mulberry leaves, more evening primrose, Jiancan grass, white clover, cup plant (Silphium perfoliatum) and the like can be added to replace mulberry leaves, so as to supplement the shortage of mulberry leaves and reduce feeding costs.

What mineral feeds are included in the diet of foxes
Mineral feeds The mineral feeds used for foxes mainly include bone meal and salt, etc. Bone meal: it is the powder made from bones after boiling and drying, and is the main source of calcium and phosphorus. Bone meal contains 40% calcium and 20% phosphorus. Bone meal needs to be supplied year-round, especially during the breeding season, and is even more important for female foxes or growing foxes, so the supply should be appropriately increased. 10-15 grams per fox per day. If the diet can supply fresh crushed bones or feed based mainly on fish, bone meal may be omitted. Salt: it is essential for maintaining the normal physiological osmotic pressure of the body

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

Disease Occurrence and Prevention Methods for Pigs at Different Feeding Stages
Disease occurrence in pigs at different feeding stages. The incidence of the three major infectious diseases of pigs. Swine fever, swine erysipelas and swine pasteurellosis are collectively known as the three major infectious diseases of pigs. In our country, the total mortality rate of affected pigs accounts for about 8% of the total raised population, and in areas with better prevention and control the pig mortality rate is also 5%. Therefore, the level of pig disease prevention and control should be raised. If the total pig mortality rate could be reduced by one percentage point each year, that would be equivalent to an additional 5 million pigs sent to market - what a huge fortune that would be. According to relevant statistics,

How to formulate lactating sow feed scientifically
Sows bear very heavy responsibilities. Lactating sows in particular must not only supply the nutrients they need themselves, but also supply the breast milk on which newborn piglets depend for survival, growth and development. Moreover, lactating sows in the high-temperature season face an even more unfavorable living and production environment, and heat stress is a severe challenge for farrowing sows. Therefore, how to scientifically formulate the summer diet of lactating sows and strengthen feeding management should be a problem that pig producers must actively consider and focus on solving. Optimizing the formulation and raising the energy level should

Which Feeds Are Likely to Poison Pigs? Pig Farmers Must Pay Attention
Pig feed poisoning can occur in all four seasons, but is more common in spring, summer and autumn. Mild poisoning affects growth and development, while severe cases can lead to death. Prevention should be strengthened at ordinary times, and the following feeds must not be used for feeding: 1. Already sprouted potatoes and their stems and leaves. Because the germ contains a large amount of solanine, it can cause toxic paralysis. 2. Fresh tender sorghum seedlings, corn seedlings and fresh flaxseed. They often cause hydrocyanic acid poisoning due to a high content of cyanogenic glycosides. 3. Moldy and deteriorated formula feed, mixed feed, grains, bran, beans, tubers and moldy oilseed meal, etc.

Detailed Explanation of Fox Feed Formulation Methods and Raw Material Ratios
The fox's digestive tract is shorter than that of the raccoon dog, its dental chewing surface is less developed than that of the raccoon dog, and the fox's large colon and cecum are also less developed than those of the raccoon dog. The time food takes to pass through the digestive tract is only 25-30 hours for the fox, while the raccoon dog needs about 40-50 hours. Therefore, the fox's ability to digest and absorb nutrients from feed is weaker than that of the raccoon dog. The fox has higher requirements for animal-based feed and vitamins than the raccoon dog. The fox's demand for feed is greatest in summer and weakens in winter. Nutritional needs differ across different biological periods; generally, they are higher during the breeding season than during the non-breeding season, and the diet should be based mainly on animal-based feed, mixed with some plant-based feed.

Nutritional Requirements of Raccoon Dogs and Scientific Feeding Methods
The survival of raccoon dogs requires 6 nutrients, which can be grouped into three major categories. 1. Animal-based feed is the source of digestible protein. It mainly includes meat, fish, eggs, fish and meat by-products, and dried animal feed. Among these, meat, milk, and offal such as heart, liver, and kidneys are sources of complete protein. They have high nutritional value and should be effectively used during the breeding period and the growing period of young raccoon dogs. Fish and meat by-products are relatively low in price and can serve as the basic protein feed year-round. Dried animal feed and feed yeast can serve as substitutes or supplements for animal protein.
