Reintroduction of the threatened red-crowned crane has been unsuccessful. Although gut microbiota correlates with host health, there is little information on gut microbiota of cranes under different conservation strategies. The study examined effects of captivity, artificial breeding and life stage on gut microbiota of red-crown cranes. The gut microbiotas of wild, captive adolescent, captive a...

Objective- Acipenser persicus is one of the most important caviar producing fishes in the Caspian Sea and one of the endangered species of the sturgeon fishes. For breeding of sturgeons, large numbers of animals have to be captured and examined to obtain sufficient numbers of mature fishes that will spawn within a few months in captivity. Design- Original study Animals- A total of 66 adult Acip...

Artificial evolution refers to any procedure that uses the mechanism of Darwinian evolution to generate a product. While this definition encompasses the evolution of organic life forms by means of artificial selection (breeding of animals, plants, or microorganisms), artificial evolution commonly refers to the instantiation of evolution within a nonbiological medium. Artificial evolution is som...

A similar proportion of beef cows and heifers exposed to estrous synchronization (ES) and artificial insemination (AI) became pregnant during the breeding season, compared with females bred via natural service breeding. Females in a breeding system that included ES and AI calved earlier in the calving season, compared with females bred with natural service, but no advantage was present for weig...

Background: Due to the seasonality reproduction of albino hamster (April to October in the Northern Hemisphere) and the need to produce blastocysts for research applications, producing and collecting blastocysts by natural mating in non-breeding season is complex in this species. In the present study in vivo blastocysts production and collection using super-ovulation and intrauterine inseminati...

Odorrana ishikawae is listed as a class IB endangered species in the IUCN Red List and is protected by law in both Okinawa and Kagoshima Prefectures, Japan. Here, in an effort to help effectively preserve the genetic diversity of this endangered species in the laboratory, we tested a farming technique involving the artificial breeding of frogs, and also promoted natural breeding in the laborato...

Artificial neural networks learn how to solve new problems through a computationally intense and time consuming process. One way to reduce the amount of time required is to inject preexisting knowledge into the network. To make use of past knowledge, we can take advantage of techniques that transfer the knowledge learned from one task, and reuse it on another (sometimes unrelated) task. In this...

In the breeding process of high quality economy parent fish, the identification and the information storage and management of the parent fish are often through artificial way. This way takes workload too much and is hard to get high reliability. It is difficult to track and manage the breeding process of the parent fish well for us. Based on the RFID (Radio Frequency Identification, RFID) techn...
