Tarine genotyping: an essential lever for optimizing your genetics

Today, genotyping is an indispensable tool for breeders wishing to improve their livestock and optimize the profitability of their operations. This technology makes it possible to evaluate the genetic potential of females and males at an early stage, thus facilitating strategic choices in terms of reproduction and selection.

Growing adoption and enhanced services

The genotyping process is gaining ground in the Tarine breed every year. In the Eleveurs des Savoie area, during the 2023-2024 campaign, 1,391 females were genotyped, an increase of 6% on the previous year and over 66% on the 2019-2020 campaign. At the same time, AURIVA and its partners, in particular EDS, have invested to improve service quality by reducing the average turnaround time for results to 27 days, compared with 39 days in 2021-2022.

Charlotte Rambert, Genetics Coordinator at EDS, emphasizes:

“In the current campaign, 1,244 females have already been genotyped. We are seeing steady progress in the Tarine breed, thanks to breeders’ growing awareness of the positive impact of the technique on herd management and long-term profitability. What’s more, at EDS we’ve dedicated more human resources to genotyping, and invested in new IT tools to improve the speed of results (27 days for the average turnaround time for results today, compared with 39 days 3 years ago). This enables breeders to make faster decisions to optimize their herds.

GENORIZON: simplified access to genomic data

To facilitate the monitoring and use of genotyping results, AURIVA and its partners have developed GENORIZON, an innovative tool for rapid, intuitive consultation of genomic data. This portal offers :

► Reactive availability of results with automatic updates when new indexations are made
► Simplified search for genotyped females and web, excel or pdf display
► A fluid, ergonomic interface where mixed-breed breeders have all results on the same platform,

In the Tarine breed, breeders will find essential information such as ancestry, production, morphology and functional indexes, as well as genes of interest: Kappa Casein and Beta Casein for cheesability, embryonic mortality, future hornlessness…

A winning strategy: genotyping, sexed semen, contribution to the collective, the Tarentais scheme and Yperios crossbreeding.

Genetic optimization involves the use of sexed semen, targeted orientation of females in
conventional semen and YPERIOS terminal crossing. By combining these tools, breeders can maximize the value of their animals:

Short gestation periods, ease of birth, calf viability, weight and conformation: by selecting YPERIOS bulls from the SECURE, OPTIMIZE or MAXIMIZE segments, you can choose which criteria to focus your crossbreeding strategy on.

However, to enable the Tarine breed to continue to progress, to maintain an interesting level of genetic variability, and to keep the economy of the selection scheme satisfactory, it is generally advisable to only crossbreed 10 to 15% of the females that are too far out of step with the dairy strategy of the herds.

Accelerated selection and genetic progress, efficient renewal and reproduction, inbreeding management and control of abnormalities… with genotyping, you can anticipate and control the future of your herd.

Whether you’re looking for functional traits, morphology or production, choose the females that will get the most out of
your system and best match your breeding strategy!
