Feed and processing of medicinal Bombyx mori
At present, the demand for medicinal Bombyx mori is booming in the market of traditional Chinese medicine, and it is profitable to raise and process it. The methods of feeding and processing are as follows: first, adult silkworms are reared. The feeding and processing of medicinal Bombyx mori should be carried out professionally in non-cocoon producing areas so as to avoid devastating effects on cocoon silkworms. The time of raising and processing can be carried out all year round. In addition to a small amount of mulberry leaves, more evening primrose, silkworm grass, white clover and cross-leaf pine vanilla can be added to replace mulberry leaves to supplement the deficiency of mulberry leaves and reduce the feeding cost.

Forced fattening of meat pigeons
The meat pigeon is 18 ~ 25 days old and its weight can reach 350 to 500g. It can be sold on the market according to the situation. But at this time, the moisture content in the meat of pigeons was higher and the subcutaneous fat was less. In order to improve the meat quality of pigeons, fattening can be forced for 5 or 7 days before sale. After forced fattening, the pigeons have crisp skin, soft bones and fragrant meat after cooking. 1 pigeons from 10 to 25 days of age can be forced to be fattened. Most pigeons of 15 ~ 20 days old and weighing 350 to 500g are used for breeding.

Prevention and control methods of silkworm without cocooning
First, the reasons why silkworms do not cocoon: 1. Pathological factors. For example, purulent disease and malacia are easy to be infected before the upper cluster, which destroys the secretory function of silk glands of silkworm, or pathogens produce a large number of toxic metabolites in silkworm body, so that the nerves of silkworms are paralyzed and cannot be cocooned. 2, physiological factors. The first is the abnormality of the central silk gland, mainly because the feeding temperature is too high or too low, the leaf quality is too tender, and the secretory gland is maladjusted, which causes abnormal silk gland, and the second is the abnormal silk gland in the anterior part, mainly because of feeding.

What if silkworms don't cocoon?
First, the main reason 1. Pathological factors. Such as purulent disease, malacia is infected before shanghai, it destroys the secretory function of silkworm silk glands, or pathogens produce a large number of toxic metabolites in the silkworm body, so that the nerves of silkworms are paralyzed and cannot be cocooned. two。 Physiological factors. The silk gland in the middle part is abnormal, mainly because the feeding temperature is too high, the leaf quality is too tender, the secretory gland is out of balance and so on. The second is the abnormality of the anterior silk gland, mainly due to exposure to a large amount of gas, fishy gas,

Nutritional formula for feeding silkworms in summer and autumn
The main feed of silkworm is mulberry leaf. Because the quality of mulberry leaf varies greatly in different seasons, it has a great influence on the yield and quality of cocoon. If the summer and autumn silkworms are fed with nutrition, the yield can be increased by 10% to 20%. The formula technology is introduced as follows: 1. Formula and feeding method of feeding agent. ① glucose solution additive. During the silkworm rearing period, if there is continuous overcast and rainy weather, the texture of mulberry leaves is tender due to lack of light, the moisture content is high, and carbohydrates are reduced. At this time, the picked mulberry leaves can be sprayed with 5% glucose solution and fed to silkworms after drying.

The breed knowledge of silkworm
The varieties of silkworms can be divided into three categories: 1. Due to different varieties, only one generation of diapause eggs occurs in a year. This variety develops slowly, after many days, the larva eats a large amount of mulberry, the silkworm body and cocoon shape are also large, and the silk is the most, but its physique is weak and can not adapt to the climatic conditions of high temperature and humidity, so it is suitable for breeding in temperate zones. 2. The second generation of diapause silkworm varieties occurs within one year, that is, the first generation produces non-diapause eggs and the second generation produces diapause eggs. This kind of product

Self-propagation and autotrophic management techniques of snakes
The following points should be paid attention to in the self-propagation and autotrophy technology of snakes: First, seed selection: Healthy and plump female snakes should be selected as seed snakes every spring. No matter poisonous snakes or non-poisonous snakes, they generally lay eggs from late June to July. The female snakes should be fed nutritious and calcium-rich food before and after laying eggs, so as to make them full and drink as much as possible. The female snake does not need to consider whether mating, female snake mating once can lay five years of fertilized eggs. 2. incubation: in order to prevent the snake eggs from drying up and sinking, the produced snake eggs should be put into the incubation tank in time for artificial incubation.

Why the old dead chicken?
Before getting ready to enter the chicks, the henhouse was not thoroughly disinfected, the heat preservation equipment was lacking, and the chicks did not drink and eat as soon as possible after entering the house, failing to raise chicks carefully and cultivate strong seedlings. In winter, only pay attention to the heat preservation of chicks, while ignoring the heat preservation of medium and big chickens, resulting in a large number of chicken deaths. Lack of long-term planning, the chicken house is simple, the basic facilities and technical conditions are poor, and it is greatly affected by the external environment. For example, the heating of coal stove is often used during the breeding period, and the temperature can not be adjusted automatically, and the temperature will rise and fall, which can easily lead to the disease and death of chickens. Do not know the technology of raising chickens. Many chicken farmers only talk about efficiency.
