For a long time, the larvae are difficult to peel off, and they are prone to cause common diseases of sudden death. Therefore, in the breeding practice, doing the following five points will improve the survival rate of pups.
Temperature requirements. The independent living young cubs begin to peel off after about 50 days of growth. At this time, the ideal peeling site for young cubs should be a multi-layered multi-layer stone cement board culture method in a plastic greenhouse. It is ideal for the larvae to be peeled off in this way. The growth was significantly accelerated, and the disease-resistance capability was enhanced. There was almost no mutual killing. At this time, the temperature of the breeding site is maintained at about 33°C, which is a good temperature for the larvae to peel off.
Suitable humidity. During depilation, the soil moisture in the active area should be slightly higher than those of other ages, especially in the dehulling stage. The young deer needs a certain amount of humidity in order to peel off smoothly. At this time, the soil moisture content should be about 20%. The relative humidity of indoor air is between 75% and 85%.
Diversification of feed. Before the larvae are dehulled, a sufficient variety of feeds should be fed to meet their nutritional needs during peeling. Feeds for this period include: Tenebrio larvae, spiders, cockroaches, maggots, terrestrial earthworms, cockroaches, aphids, and rice moths. These insects contain different hormones in their bodies. Different hormones can play a key role in the dehiscence of young calves.
Stocking density. During the dehydration of pups, the smaller the stocking density, the higher the survival rate of pups, the faster the growth rate, and the lower the dehydration mortality rate. The stocking density is about 3000 pieces per cubic meter.
Careful management. The cubs are no longer eating 7 days before peeling. At this time, the feed should be replaced with fly maggots, rice moths, spiders, and small earth elements. The cubs have completely lost their ability to defend themselves during peeling and cannot protect their own safety. Therefore, Tenebrio more than 1.5 cm should be bred and fed before 10 days of depilation to prevent Tenebrio bite or eat the peeling lice.
Multi Span Plastic Film Greenhouse
Arch greenhouse is a kind of economical greenhouse, which is welcomed by the users with graceful curve form and low cost. It has beautiful appearance, fluent visual, reasonable structure and good performance for keep temperature. It is economical greenhouse because of its relatively low manufacturing cost. It can be applied in most areas of China. Double membrane greenhouse is used more in north of China, while single film greenhouse is used more in southern region. It can get maximum sunlight when visible light is within the scope of 0.4 to 0.7 microns and form a thick envelope, which can effectively prevent heat loss and prevent the invasion of cold air. Adopting a double membrane can greatly improve heat preservation performance of the greenhouse and save operating cost. The top cover material is polyethylene lifelong anti-fog and anti-dipping film po-covering. The outer of it has the function of UV protection and the inner has the function of preventing from the sets of dew. According to the needs of customers, the sides of the greenhouse can be covered with polyethylene lifelong anti-fog and anti-dripping po-covering or polycarbonate hollow plate.
