A method for artificially assisted breeding of tigers

Abstract

The invention discloses an artificial assisted breeding method for tigers, which adjusts the formula milk powder of tiger cubs and the formula of nutritional additives for tigers such as South China tigers in the breeding period. By adding probiotics, digestive enzymes, DHA, vitamins and trace elements, the focus is to solve the problem of feed The formula cannot meet the growth and development needs of cubs, and problems such as cub absorption and indigestion. The survival rate of newborn cubs at 0-120 days old is 90%, and the survival rate of cubs at one year is 90%. The added nutritional additives make the pregnancy rate of paired South China tigers more than 50%, and the incidence of stillbirth or weak fetus is lower than 30%.

Description

technical field [0001] The invention relates to an artificial assisted breeding method for tigers. Background technique [0002] The South China tiger Panthera tigris amoyensis is a unique tiger subspecies in my country and the common ancestor of all tiger subspecies in the world (Herrington, 1987). At the same time, the South China tiger is also the most endangered among the five existing tiger subspecies (Tilsonet x1., 1997). The International Union for Conservation of Nature (IUCN) has listed the South China tiger in the "Red Data Book of Endangered Species" in 1999, and the endangered level is E (endangered level). The risk of extinction is greater than that of any other taxa at the same level. According to the principle of priority protection for taxa units in the world, it should be protected first. [0003] Due to indiscriminate hunting and deforestation of mountain forests, the habitats of South China tigers have been continuously reduced, and the number of wild re...

Problems solved by technology

[0004] Many researchers have conducted research on the artificial assisted breeding technology of South China tigers, and they often adopt the phenomenon of breeding tigers in cages since childhood, but this practice often leads to premature mating of tigers, and it is inevitable that tigers will attack each other and become disabled. The phenomenon

Difficulty conceiving, miscarriage, or stillbirth in captive tigers is mostly related to the fact that the tiger’s nutritional needs are not met. Most captive tigers only provide chicken skeletons, pork and beef, and rarely provide other nutritional supplements. Insufficient levels of sulfonic acid, arginine, vitamin A and arachidonic acid, which are key nutritional factors affecting tiger breeding

Studies on artificial breeding of South China tigers, but most of them use goat's milk or cat milk powder imported from abroad as the artificial milk source. Because the composition of goat's fresh milk is quite different from that of tiger's self-secreted milk and sweat, it is necessary to use The success rate of artificial breeding method of goat fresh milk as an alternative milk source for tigers is not high

Using foreign cat substitute milk powder as an artificial milk source can improve the survival rate of tigers, but there is also a certain difference in the milk composition of cats and tigers. At the same time, the growth and development needs of tigers are much higher than those of cats. Therefore, in the process of raising young Diseases such as inability to stand and walk, visual impairment, and indigestion are prone to occur in Zhongzhong. More importantly, this alternative milk powder has no independent intellectual property rights, which makes the source difficult and the price remains high.

Secondly, the unreasonable design of the rearing cage is also an important reason. When the South China tiger cubs are born, their body temperature regulation ability is not strong, they cannot stand and walk, they need light to promote calcium absorption, and they are prone to frostbite and crush injuries during artificial rearing. , rickets, and skin damage and infection, which are also one of the key factors restricting the success of artificial breeding of South China tigers
