In Chubut, a team of researchers from the INTA Animal Reproduction Center presented the first Patagonian lambs obtained by an advanced method. We’re talking about in vitro reproductive biotechnology. This is an innovative technique that accelerates the obtaining of improved genetic material and at a lower cost, compared to traditional techniques. “We achieved something new and innovative for the region,” said Andrés Buffoni, director of the INTA Chubut Animal Reproduction Center (CRA).

“ They are techniques applied to animal reproduction that seek to obtain, in a rapid and massive way, selected genetic material . Such techniques contain certain desirable characteristics for wool and meat production,” Buffoni said. The INTA Animal Reproduction Centre together with the Corporación de Fomento (CORFO) worked on the procedures of embryonic culture in laboratory. In this sense, Livio Sala, researcher at the CRA, pointed out the importance of the work. “We managed to produce sheep embryos, transfer them to the receiving females and record the birth of two twin females and one male, in good health.”

Benefits of biotechnology

After the gestation period, the pregnant females gave birth three lambs in vitro. Two twin females weighing 4 and 4.6 kilograms, respectively, and a male of 5.6 kilograms.

Among other benefits, in vitro reproductive biotechnology reduces the cost for obtaining embryos. In addition, it avoids the use of hormones in donor females and there is a greater use of semen. The procedure is minimally invasive and is performed by laparoscopic follicular aspiration. The one that can be done every ten or fifteen days on the same donor sheep. Its implementation aims to obtain eggs from genetically superior females.

This progress was made possible thanks to a technological linkage agreement signed between various actors. The province of Chubut, the Development Corporation and INTA for the breeding of sheep in the region.
