No impact on reproductive parameters such as the farrowing rate and the total number of piglets born was observed by performing two inseminations in synchronized sows compared with that in the control group (ZAK et al., 2009; ZAK et al., 2010).
A meta-analysis was performed including the studies from 2008 to 2015 (n=5,238), in which the triptorelin protocol was followed in weaned sows, and the traditional farrowing rate was observed to be superior in the control group, compared with that in the triptorelin-induced sows (89.7% vs.
(2017), a lower adjusted farrowing rate was observed in sows inseminated once outside the optimal interval (21%) after buserelin application compared with those inseminated within the optimal time (91.4%).
The biggest challenges in the practical application of FTAI are those related to the possibility of a reduction in the farrowing rate due to certain protocols and field observations.

Socially intermediate sows had lower farrowing rates, fewer pigs born, and fewer pigs weaned/litter.

These factors, while important, should not be the focus of efforts toward increasing PPSY unless the farrowing rate and the number of nonproductive days are already well under control.

In this example, the farrowing rate is a fraction (0.80, not 80%) and crate occupancy is a fraction (1.10, not 110%).
Farrowing rate refers to the number of sows giving birth compared to the number bred.
The farrowing rate is determined in the breeding area.
Different housing systems affect farrowing rates, however results are still inconsistent.
