How to raise nursing puppies? A complete guide to scientific rearing methods
Puppy: refers to a dog from birth to weaning (around 45 days of age); puppies do not open their eyes until 12-15 days after birth, have poor mobility, but grow fast and have relatively high nutritional needs. Therefore, the rearing of puppies should be done as follows: 1. Get colostrum in time. The milk secreted by the mother dog within 1 week after giving birth is colostrum. Colostrum is rich in gamma globulin, which after being absorbed by the intestinal tract forms antibodies in the puppy's body and can enhance the puppy's disease resistance. Puppies must get colostrum in time, otherwise the gamma globulin will be destroyed by digestive juices

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

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.

Detailed Guide to Potato Storage Methods: Teaching You How to Store Scientifically
I. Chemical and Physiological Changes During Storage. When potatoes are harvested, the tubers generally contain about 75% moisture. During storage, they have very strict requirements for temperature, humidity, light and air conditions. If these are not adjusted properly, they will cause adverse changes in physiological state and chemical composition. During storage, the physiological and chemical composition of potatoes is constantly changing. With changes in temperature, humidity and light, their respiration intensity changes accordingly. Due to respiration, weight can be reduced by 6.5-11%. If maturity is insufficient, nitrogen fertilizer is excessive, or potassium chloride alone is used, the weight loss will be greater.

How to Scientifically Choose Rice Varieties for Planting
How to scientifically choose rice varieties for planting should follow these principles: (1) Certified varieties with strong resistance. (2) In the same village or town, large-scale planting of a single variety should be avoided; 3-4 varieties should be mainly promoted and planted in combination. (3) Since this year's climatic conditions are not very favorable, varieties with a slightly earlier maturity period should be chosen. (4) Choose varieties sold by legitimate manufacturers. It is best to buy seeds from the breeding unit, because the breeding unit understands the characteristics of the varieties and the suitable regions. The seed purity is relatively good,

How to Care for Feverish Sick Pigs? A Detailed Guide to Scientific Care Methods
The normal body temperature of pigs is 38°C-40°C; if it persistently exceeds 40°C, it is fever. Prolonged continuous high fever accelerates the body's catabolism, disrupts digestive function, lowers resistance, and can even cause coma or heart failure. The treatment principles for feverish sick pigs are as follows: immediately isolate feverish sick pigs, and thoroughly disinfect the contaminated environment. Before the cause is identified, as long as the fever is not excessively high, generally do not use antipyretic drugs at will. While using antibacterial drugs, attention should be paid to supplementing nutrients.

A Comprehensive Guide to Scientific Control Methods for Soybean Aphids
Soybean aphids are commonly known as "ni chong" (greasy bugs) or "mi chong" (honey bugs). They mostly gather on the growing points, top leaves and backs of young tender leaves of soybean plants, piercing and sucking sap to cause damage. This results in leaf curling, plant stunting and reduced yield, and they can also transmit viral diseases, causing yield loss and quality decline. This pest begins to appear in soybean fields in mid-to-late June, and causes severe damage during hot, dry weather. Soybean aphids have a very strong reproductive capacity; a single female can produce 50-60 offspring, and under suitable conditions, young aphids can give birth after about 4-5 days, and can reproduce 15

How to fertilize rice? Mastering scientific fertilization methods is key
Use organic fertilizer together with chemical fertilizer. Organic fertilizer is rich in organic matter, can build up soil fertility, provide a variety of nutrients, and also supply compounds with auxin- and hormone-like properties. Applying organic fertilizer helps maintain the nitrogen reserves in rice paddy soil. Organic fertilizer releases nutrients slowly, while chemical fertilizers are mostly quick-acting fertilizers that supply nutrients rapidly; using the two together makes the nutrient supply relatively steady. The organic acids and humic acids in organic fertilizer can bind with iron and aluminum in the soil, reducing the fixation of phosphate fertilizer by the soil and increasing the amount of available phosphorus and the

Scientific Feeding Methods and Technical Key Points for Growing Sheep
Whether the feeding of growing sheep is reasonable plays a decisive role in body conformation and growth rate. Improper feeding can cause sheep to be too fat, too thin, or experience stunted growth at a certain stage, resulting in undesirable conformations such as long legs, short body, and pendulous belly. Formula for growing sheep concentrate supplement Feed type Roughage type High-quality hay type Corn silage type Dry corn stalk type (%) (%) (%) Corn 60.00 58.50 58.50 Wheat bran 15

Detailed Explanation of Key Technical Points for Scientific Application of Fishery Drugs
Fishery drugs are all substances used to prevent, control and treat diseases, pests and harm of aquatic animals and plants, promote healthy growth of cultured species, enhance the body's disease resistance and improve the quality of aquaculture water. Here we specifically introduce several correct medication methods for the prevention and treatment of aquatic animal diseases: 1. Apply drugs according to the disease. There are many varieties of fishery drugs, and their physical and chemical properties differ. Therefore, before using fishery drugs, the main diseases and pathogens of the cultured prevention and treatment targets must first be accurately diagnosed, a treatment plan must be made, and then a suitable drug variety must be selected for targeted treatment; otherwise, it will not only fail
