Embryo Transfer Becomes a Fundamental Tool for Genetic Progress - Dauren Makatbayev

According to Dauren Makatbayev, the traditional breeding model faces several limitations, including data scarcity, high dependency on human factors, and unpredictability of results. In this context, the key task is to shorten the time between generations and increase selection accuracy.

Previously, embryo transfer was considered an additional technology, but today it takes center stage. According to the presented data, the share of IVF in global practice has grown from 8% in the late 1990s to about 80% in recent years.

The key advantage is the significant acceleration of genetic herd renewal by reducing the intergenerational interval and more intensive use of the best animals.

The expert emphasized that the implementation of IVF addresses several tasks simultaneously:

• allows more offspring to be obtained from the best animals in a short period;
• enables work even with pregnant cows;
• ensures maximum utilization of valuable genetics;
• reduces the influence of random factors in reproduction.

Moreover, the technology itself becomes more predictable economically: the production cycle from obtaining an egg to an embryo takes about 7 days, fundamentally changing the speed of decision-making on the farm.

Dauren Makatbayev presented a clear technological process chain consisting of three key stages:

1. egg collection (aspiration);
2. laboratory fertilization;
3. embryo transplantation.

An important feature of the model is the possibility of regular (weekly) material collection without hormonal stimulation, which reduces stress on animals and simplifies process management.

The economic logic is particularly emphasized: payment is only made for first-class embryos, reducing risks for farms and making investments more manageable.

However, the speaker noted that the technology itself is not a "magical solution." Its effectiveness directly depends on herd management quality.

Three basic conditions for successful implementation were highlighted:

• donor management;
• obtaining a high-quality embryo;
• recipient management.

Special attention is given to the selection of animals: age, condition, reproductive status, and health directly affect the result.
