Analysis of the Causes of Explosive Fish Mortality and Prevention and Control Measures
2. Countermeasures for bacterial and parasitic diseases. For bacterial diseases, the main approach is to control the reproduction of pathogenic bacteria in the pond water and keep their numbers below the disease-causing threshold. This requires routine regular disinfection, using "Yujunjing", "Yujunjing No. 2", "Jundi" or strong chlorine powder once every 7-10 days to prevent excessive reproduction of pathogenic bacteria. After a bacterial disease occurs, disinfect continuously 2 times with a disinfectant, and at the same time mix drugs such as "Chuxueping", "Jingbo Baoxueping", "Yubingkang", "Yufubao" or "Jianyule" into the feed

Analysis of Factors Affecting the Pigmentation of Sanhuang Chickens and Existing Problems
In recent years, with the development of the domestic poultry industry and the continuous improvement of people's living and consumption standards, consumers have become increasingly discerning in their demand for meat products, and people in East China are particularly fond of Sanhuang chickens. In fact, the yellow color deposited in the shanks and subcutaneous fat of chickens is all lutein, and lutein is a general term for a class of natural pigments. Since chickens cannot synthesize lutein themselves, all lutein present in the chicken body comes from the feed. So, what causes the differences in chicken pigmentation? The following analysis examines this one by one.

Analysis of the Causes of Mushroom Death and Control Measures
Mycelium aging causes mushroom death. When the mushroom spawn is subcultured too many generations, or the spawn is produced at too high a temperature, stored improperly, or kept for too long, the mycelium can degenerate and age, its vitality declines, and insufficient nutrient accumulation within the body leads to the shrinkage and death of mushroom buds. Countermeasures: Select high-quality spawn and promptly discard contaminated spawn; create conditions suitable for mycelial growth and development, keep the room clean and hygienic with fresh air, and strictly prevent high-temperature culturing; use spawn as soon as it is prepared and avoid long-term storage. Continuous high temperature causes mushroom death. Before fruiting,

How to Increase Royal Jelly Production? Analysis of Practical Technical Measures
Increasing royal jelly production is an important guarantee for improving the economic benefits of beekeeping. To increase royal jelly production, the following 5 technical measures should be implemented well. 1. Cultivate strong colonies, bringing the bee colony strength to a full colony of 12 frames or more. Among bees, royal jelly is secreted by young bees and is the main food supplied to the queen bee and bee larvae. Therefore, to increase royal jelly production, there must be strong colonies with more young bees, and the royal jelly production colonies must be adjusted in a timely manner. If there are only 6-7 frames of full bees, it will be impossible to achieve high royal jelly production. For this reason, it is necessary to increase young

A Comprehensive Analysis of the Current Status of New Peach Variety Breeding in China
I. Breeding of Fresh-eating Peach Varieties with Different Maturity Periods The breeding of fresh-eating peach varieties has always occupied a dominant position in China. Over the past 50 years, a large number of excellent new varieties (lines) with different maturity periods have been bred, which to a certain extent has changed the situation of overly concentrated market supply. 1. Breeding of early-maturing varieties. Since there are relatively few early-maturing peach varieties in production, early maturity and high quality have become the main goals of peach breeding. Through the efforts of breeders, a number of excellent early-maturing varieties have been bred using crossbreeding and bud sport selection methods. Most of these new varieties
