[Retracted] Study on Various Luteal Characteristics Using Doppler Ultrasonography for Early Pregnancy Diagnosis in Nili-Ravi Buffaloes

Table 1

Comparison of luteal size (LS), plasma progesterone (P⁴) concentration, and luteal blood flow (LBF) monitored with color and power Doppler imaging (CDI and PDI) in nonpregnant Nili-Ravi buffaloes () from day 5 to 21 post-AI.
