embryo transfer - Opis:
- Alpacas are new breeding species in Poland. They have been bred for over a decade and interest in them is constantly growing. It is estimated that their number in our country may already reach 3000 individuals. As knowledge of the reproductive physiology of South American Camelids (SACs), progresses, it becomes clear that those processes in other livestock cannot be extrapolated to camelids. Due to that fact, the authors decided to present the specificity of alpacas reproduction. The first part of current article presents the general understanding of sexual dimorphism, fertilization and the course of pregnancy, which in alpacas takes from 327 to 346 days (mean 340). Females become pregnant as a result of natural mating. The own, breeding male, as well as the male from other farm can be used. The male should be healthy, proven and of high breeding quality, since genetically transmitted defects are very common in alpacas. Breeding females in good condition should produce the offspring (Spanish: cria), every year. This article describes an important topic of research into reproductive biotechnologies such as artificial insemination and embryo transfer. Insemination is not commonly used in alpacas and is believed to have a low overall performance. Despite numerous difficulties in supporting reproduction through insemination, embryo transfer technology in alpacas develops excellently. Embryo transfer is applied for the better use of genetic potential of high-quality females and for obtaining more young ones.
