In beef and dairy cattle, one of the main limitations of the reproductive efficiency and genetic improvement is the gap of generations. Historically speaking, this intermission has been mostly reduced through the development of reproductive biotechnologies, in which the in vitro Fertilization – IVF – outstands. What makes this biotechnology unique is that it:
- Provides the biggest number of descendents of genetically superior animals in the same period of time, rising the profitability per animal;
- Reduces gap and generations;
- Is applicable in several reproductive phases of the female bovine: prepubescent heifer, pregnant (until 100 days), after parturition, cyclic and senile cows;
- Exempts the intensive hormone use;
- Utilizes animals that do not respond to superovulation;
- Optimizes the semen use and the mating planning;
- Presents the best cost-benefit relationship when compared the other existent techniques.
