TUT İPƏKQURDUNUN SƏNAYE YEMLƏMƏLƏRİ ÜÇÜN OPTİMAL BƏSLƏNMƏ NORMALARI

Abstract

The article notes that non-regulation of temperature and relative humidity in silkworm feeds can lead to malnutrition, digestive disorders, edema and inhibition of growth, as well as to a number of diseases. To avoid this, the heat in the greenhouse should be adjusted according to optimal temperature norms. In the first years I-II-III the average temperature in the greenhouse is 25.5° C, in IV-23.5 ° C, in V-24 ° C. Normal relative humidity should be adjusted during feeding in the greenhouse to avoid the above. In the first I-II-III years it is normal when the relative humidity in the greenhouse is 70%, in the IV age 70% and in the V age 65%. If the temperature and humidity are not in the normal range during the cocoon transition process, the turnover breaks, resulting in loss of product. The normal temperature during the cocoon transition process should be 23.50 C and the relative humidity should be 65%. One of the main factors affecting the yield of silkworms is the correct regulation of field norms at different ages. If an age-appropriate area is not created, the silkworm becomes ill, leading to malnutrition. Normal field units (per 1 box of silkworms) were assigned at different ages: I year-2.5 m2, II year 6-7 m2, III year 15-17 m2, IV year 30-35 m2, V year 55-60 m2. The amount of greenhouse gases, the flow rate and the volume of air should be normal during feeding in the greenhouse. Therefore, the greenhouse air must be changed frequently during feeding. The presence of toxic gases, such as ammonia, hydrogen sulfide, is unacceptable. The speed or lack of airflow is harmful to the silkworm. During feeding, the airflow rate is 0.1 m/s. When feeding of silkworms is applying in accordance with established norms, biological and technological indicators of silkworms are high. Key words: Bombyxi mori, silk, temperature, relative humidity
