The meat is delicate and delicious, and it is a good tonic for the game. It not only has fast growth and development but also has strong disease resistance and high egg production rate. However, how to improve the fertilization rate of egg-laying is a concern for many farmers.

First, light: Sexual maturity for about 6 months, that is to begin mating and production of eggs, during the production of eggs to maintain 18 hours of light every day, artificial light to be added to the time, the light should be stable, the light time suddenly changes, the light suddenly Obvious and dim will affect the normal fertility and the fertilization rate of eggs, generally 3 watts per square meter, bulbs from the ground 1.8 to 2 meters is appropriate.

2. Density: 20 to 30 animals per square meter for breeding commodities, 10 breeding animals per square meter, and no more than 15 at most. If the density is too high, the mating ability of each male can not be fully utilized to reduce the fertilization rate of the breeding eggs. , affect the hatching effect.

3. Drinking Water: As the temperature rises, the demand for water is increasing. You must keep enough clean drinking water, change the water once a day, and wash the sink with 0.1% potassium permanganate solution to ensure the species. The health of the cricket grows, thereby increasing the mating ability of the male cricket and the egg production rate of the female cricket.

Feed: While maintaining adequate drinking water, attention must be paid to the feeding of the feed, during the breeding period, the nutrients should be comprehensive, metabolic energy 2750 ~ 2800 kcal, crude protein more than 18%, full of essential amino acids, and pay attention to trace elements And vitamins added during this period of feed formulation: yellow corn (crush) 50%, wheat flour 11%, bean cake 16%, imported fish meal 10%, bone meal 3%, shell powder 1.1% salt 0.4%, additive 0.5%, mixed Evenly feeding 3 to 4 times a day, only the amount of 30-35 grams a day.

Fifth, the proportion of male and female: In order to improve the fertilization rate of male eggs, male and female fertilization is the key, and the ratio of male and female is 1:4. Since the male fertilized can produce 8 to 10 fertile eggs at a time, press 1:4. The ratio ensures that the fertilization rate of eggs is above 90%. If too much public money is raised, the raising cost will increase, which will reduce the economic benefits.

6. Feeding methods: Cockroaches can be kept in a free range or in cages. Generally, cages are raised in large numbers. Due to the three-dimensional culture of cages, the breeding area can be fully utilized. The ratio of 1:4 (1 group) per square meter of cages Can raise 2 to 3 groups, this can help mothers who do not want to mate to evade the pursuit of public funds, in order to achieve the purpose of improving the fertilization rate of eggs.

Stevia

Stevia sweeteners are derived from the leaves of the Stevia rebaudiana (Bertoni) plant, an herbal shrub native to South America. The stevia plant has been used for food and medicinal purposes for hundreds of years, and its leaves and crude extracts have been sold as dietary supplements. Purified extracts of the sweet substances found in the stevia leaf, called steviol glycosides, are considered to be generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA). However, whole stevia leaves and crude leaf extracts are not permitted to be sold as sweeteners in the U.S. because there is not enough toxicological information on these products, according to the FDA. Stevia sweeteners are made by extracting steviol glycosides from the leaves of the stevia plant and purifying them to remove some of the bitter attributes found in the crude extract.
