Technical measures to prevent secondary cocoons of silkworm, Bombyx mori
Raising silkworms and choosing high-yield and high-quality cocoons is the key to high yield and harvest. In the process of sericulture, many factors will produce many cocoons and reduce the benefit of sericulture. In order to avoid the occurrence of secondary cocoons, increase the cocoon rate and reduce the secondary cocoon rate are important links to further increase the economic benefits of sericulture households. The related technical points of preventing secondary cocoons are briefly introduced as follows: 1 strengthening the feeding and management of 1.1 small silkworms are covered with plastic film, which can not only keep the mulberry leaves fresh, but also promote the larvae to like to eat, which is beneficial to the larvae to eat and lift.

Adjustment of feed formula by damp-heat measures for pigs
1. Adjust the feed formula to increase the feed intake of pigs. 1. Under the condition of high temperature, in order to reduce body heat gain and heat dissipation burden, it is bound to reduce feed intake, resulting in insufficient intake of nutrients such as energy and protein in pigs, and make necessary adjustments to the feed formula. it has become one of the effective measures to overcome heat stress. The more the body heat of nutrients increases in ①, the more serious the heat stress after feeding. Fat has the advantages of small volume, high net energy value and less body heating. it is an ideal energy source for pigs under high temperature, and can be added less than 5% to feed.
