Pay attention to the prevention of rat poisoning before silkworm sericulture, silkworm racks and walls to maintain a certain distance, silkworm frame around the feet to sprinkle with lime powder or silkworm medicine to prevent rats climbing. It is also necessary to prevent flies from entering silkworm and endangering silkworms.
Pay attention to the high temperature in hot summer and autumn. In the morning, spray well water, hang damp cloth or straw curtains in the silkworm room, close the doors and windows during the day to prevent hot air flow into the room, and keep the temperature low at night. Open doors and windows all night. Indoor use of fans blowing breeze, but also conducive to indoor cooling.
Clean up the diseased silkworm in time and find out that the diseased silkworm should be promptly cleaned up and cannot be thrown away. It should be put into a disinfection basin filled with bleach solution or lime slurry.
It cannot be dumped. The silkworm sand contains a large number of pathogens. Therefore, it cannot be thrown in disorder, and it cannot be suntanned around Jamsil. It should be concentrated in the field or placed in a pit to prevent the spread of pathogens.
Pay attention to the reasonable storage of leaves in summer and autumn, high temperature and humidity, rapid pathogen reproduction, should pay attention to planning the collection of leaves, timely transport leaves, can not let the accumulation of excessive thickness, to prevent fever deterioration and induce silkworm disease; do not feed overnight mulberry leaves, avoid feeding wet leaves; The mulberry leaf should not be sprinkled on it, and sand must be removed frequently. Fresh lime powder, dried straw, and other materials should be used to prevent the growth of pathogens.
Additives mainly refer to various antibiotics, antioxidants, mold inhibitors, binders, colorants, flavouring agents, health care and metabolic regulation drugs, etc. are conducive to enhancing feeding effect, conducive to the production and storage of non-nutritive Feed Additives and their formulated products. It is mainly divided into food additives, feed additives, concrete additives, and oil additives.
Food additives refer to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are a term that refers to the chemical synthesis or natural substances added to food to improve the quality, color, aroma and taste of food, as well as the need for preservation and processing technology. Food additives are generally not food and may not have nutritional value, but they must conform to the above definition, that is, they do not affect the nutritional value of food, and can prevent food spoilage, enhance food sensory properties or improve food quality.
Feed additives, also known as feed additives, refer to the general term of additives manually added to formula feed in order to make up for the shortcomings of formula feed and some special needs. The functions of additives include: 1) insufficient nutrients in feed; 2) preventing deterioration of feed quality; 3) improving palatability of feed and utilization rate of feed; 4) enhancing disease resistance of feeding animals, promoting normal development and accelerating growth and production of feeding animals; and 5) increasing the output and quality of feeding animal products. The dosage of these special substances is very small, generally according to a few percent of the formula feed to several parts per million (mg/kg), but the effect is very significant. According to some data at home and abroad, it is considered that the average efficiency can be increased by 5%-7%, sometimes up to 10%-15%.
