Civet breeding "four matching"
The selection of civet cats is the prelude to breeding, in order to consolidate and improve the good quality of both parents, to cultivate new beneficial traits purposefully and systematically, and achieve the purpose of obtaining the ideal offspring. The selection is usually considered from several aspects such as the quality, kinship, age, and body type of the major traits of the parents. Matching is divided into quality matching, kin selection, age matching and body shape matching: First, quality selection includes homogenous matching and heterogeneous matching. Homogeneous selection of male and female mate mating with the same advantages as the main selective form aims to consolidate and develop these excellent qualities for future generations. For homogenous selection, the phenotype of the male raccoon must be relatively higher than the phenotype of the female trait in the main traits. Heterogeneous selection mainly selects male and female mate mating with different genetic traits, aiming to enable their offspring to obtain different traits that have both parents, or to combine new parents or breeds to develop new varieties or strains. Second, kin selection is mainly to avoid inbreeding, inbreeding has a negative impact on the lower heritability traits, some of the harmful stability genes, due to inbreeding to achieve homozygosity, so that growth and development are blocked, there is a decline in viability phenomenon. Third, the age matching breed raccoon's age selection and pairing production effect has certain influence. Generally, the genetic performance of the 3-6-year-old species of raccoon is relatively stable, and the matching effect is better. It is usually better to use the young male raccoon as a female cub, a male cub or a female cub or a male cub into a female cub. Fourth, the size of the matching should be a large public veterinary mating with large or medium-sized female veterinary, medium-sized male raccoon mating with a small female raccoon, must not be taken with a big male raccoon with a small female cub and a small male raccoon with a big female cub and a small male raccoon with a small The practice of the beaver. Group mating can be used in production. The method is to classify the female sires with the same genetic traits as a group, and then select a few suitable male raccoons to form a matching group. Random mating can be used in the group. Emergency rescue clothing is one of the important equipments to protect the personal safety of firefighters who are fighting on the front line of fire fighting. From the perspective of protection, it must have fire resistance, heat resistance and heat insulation, as well as strong toughness to prevent the impact and collision of sharp objects, and prevent chemical damage to the skin. emergency rescue suit,Ice Rescue Suit,Rescue Dry Suit,Water Rescue Suit,Good as water rescue rope cutter,Flame Retardant Safety Protective Clothing joho(HK) Technology Co. , Ltd. , https://www.joho-safety.com
