Panda milk preservation method

Abstract

The invention discloses a panda milk preservation method. The method comprises the following steps: storing panda milk at -80 DEG C for 24 h, and then putting and storing the panda milk in liquid nitrogen. The preservation method makes the panda milk preserved for a long time, and results of analysis show that the panda milk preserved by using the method can effectively improve the cell viabilityin the panda milk, and the preservation method is more beneficial to healthy growth and development of young pandas compared with a conventional storage mode.

Description

technical field [0001] The invention relates to a method for preserving animal milk, in particular to a method for preserving giant panda milk. Background technique [0002] The giant panda (Ailuropoda melanoleuca) is a rare animal unique to my country. Improving the success rate of giant panda breeding and raising young has always been the focus of captive giant panda conservation work, and it is also a difficult research point. Giant panda cubs are born prematurely, and their later development is completely dependent on breastfeeding. Breastfeeding of giant panda cubs plays a very important role in the survival rate and healthy growth of giant panda cubs. Because the composition of giant panda breast milk is complex and diverse, and has many biological functions, it not only provides nutrients for the growth and development of cubs, but also has immune protection functions. Some previous studies have analyzed some nutritional components in captive giant panda breast milk,...

Problems solved by technology

[0004] At present, conventional milk preservation methods include cold storage and cryopreservation, but these conventional preservation methods have some problems in the preservation of giant panda milk

For example, refrigerated storage at 4°C can better preserve the main nutrients of milk, but the storage time is short, generally only about 3 days, which is suitable for short-term storage; direct frozen storage, such as -20°C, -80°C or -196 ℃ freezing, it can be stored for a long time, but this kind of preservation can only preserve the nutrients in the milk, and the cell viability in the milk has no advantage

However, there is no report on the effect of breast milk cryopreservation on the cells in milk
