A new device for deep cervical artificial insemination in gilts reduces the number of sperm per dose without impairing final reproductive performance

Table 1 Reproductive parameters obtained from gilts inseminated by CAI (2.5 × 10⁹ sperm/85 mL) or Dp-CAI (1.5 × 10⁹ sperm/45 mL). Data show rate (%) or mean ± SD. No statistically significant differences were observed in any of the parameters studied (P > 0.05)
