- Abstract:
- ... The alpaca (Vicugna pacos) is a ruminant livestock species in the South American camelid family. There are more than 9 million South American camelids globally that make important contributions to the livelihoods of rural farmers through conversion of low quality roughages to high quality food and fibre. Reproductive biotechnologies for alpacas are not well developed compared with those for other ...

- Abstract:
- ... Alpacas, like other camelids, are classified as induced ovulators because an external stimulus is required for the occurrence of ovulation. Recent studies have identified the β-nerve growth factor (β-NGF), a protein present in the seminal plasma (SP), as responsible for inducing ovulation in this species and having potent luteotropic function. We speculate that SP can be used in reproductive biote ...

- Abstract:
- ... The objective of this study was to compare the effectiveness of cryopreserving in vivo-produced alpaca embryos by slow freezing v. vitrification. The embryos were produced from 9 female alpacas at Fundo Mallkini, Puno, Peru, located at 4300m elevation. The donor alpacas were synchronized by induction to ovulate with an injection of gonadotropin-releasing hormone (0.0084mg of buserelin acetate) and ...

- Abstract:
- ... Alpacas can only produce one offspring per year. In order to accelerate the genetic gain of a herd, superovulation and embryo transfer can be used to produce multiple embryos from superior females. We hypothesized that the use of dual siring with superovulation would result in the production of multiple embryos sired by different males. After administration of the superovulation protocol, receptiv ...

- Abstract:
- ... Over the past 3 decades, and similar to the horse industry, fresh embryo transfer has been widely practiced on large commercial scales in different camelid species, especially the dromedary camel and alpaca. However, the inability to cryopreserve embryos significantly reduces its broader application, and as such limits the capacity to utilize elite genetic resources internationally. In addition, c ...

- Abstract:
- ... Intraspecific and interspecific embryo transfer in domestic South American camelids is developing into a well-established technique. Reports reveal many benefits of using reproductive biotechnologies to allow rapid propagation of alpacas and llamas of high genetic merit (e.g., high fiber quality, preserve color variation). The objective of this review is to provide up-to-date information about emb ...

- Abstract:
- ... Embryo transfer offers great advantages to South American camelid farmers to reach their breeding goals but the technology still plays a relatively minor role in comparison to other domestic farm animals like cattle. The aim of the present study was to analyse a data set of 5547 single or multiple ovulation embryo transfers performed in commercial alpaca farms in Australia to determine the factors ...

- Abstract:
- ... The development of assisted reproductive technologies such as embryo transfer (ET), artificial insemination (AI) and in vitro fertilization (IVF) in South American camelids is considerably behind that of other livestock species. Poor success of the embryo transfer technique has been related to a lack of an effective superstimulatory treatment, low embryo recovery rate, and the recovery of hatched ...
