Evidence & Trials: FemEXX in Cows and Buffaloes

FemEXX is not a theoretical concept. Its performance has been evaluated through field trials, university research, and international collaborations across cows and buffaloes. These studies consistently show a higher proportion of female calves in FemEXX-treated groups compared to typical expectations and control groups.

Case Study 1

Trial conducted by KMF, Karnataka Milk Federation, 2022

  • Conducted with Karnataka Milk Federation (KMF)
  • Species: Dairy cows (HF & Jersey crossbred)
  • Outcome:
  • Female calves born: 78%
  • Male calves born: 22%

This trial shows substantially higher female calf rates than the ~50:50 ratio seen under conventional conditions.

Study Results Table
Particulars Control Group Trial Group (FemEXX)
Total Confirmed Pregnancy 219 225
No. of Animal Calves 217 218
No. of Female Calves Born 108 169
No. of Male Calves Born 109 49
Case Study 2

Trial conducted @ LPM Dept, Bidar, Karnataka veterinary Animal & Fishery Sciences University ( KVAFSU), 2024

  • Conducted with Karnataka Veterinary, Animal & Fisheries Sciences University (KVAFSU), Bidar
  • Species: Dairy cows (HF & Jersey)
  • Total animals: 170
  • Outcomes:
  • Female calves born: 120 (71%)
  • Male calves born: 50 (29%)

This research setting provides strong academic validation of FemEXX as a female sex ratio enhancer in dairy cows.

FemEXX 60 53 38 71.7 30 78.94
FemEXX + Suppl 57 47 35 74.5 27 77.14
Suppl 55 53 41 77.4 17 41.46
Control 60 48 40 83.3 17 47.5
Case Study 3

Trial Conducted @ AFU Nepal in collboration with ILRI, International Livestock Research Institute, 2025

  • Conducted with Agriculture & Forestry University (AFU) in collaboration with International Livestock Research Institute (ILRI)
  • Species: Dairy buffaloes
  • Outcome:
  • Female calves born: 79%
  • Male calves born: 21%

These results confirm that FemEXX’s concept also applies to buffaloes, extending its relevance to buffalo-dominant dairy regions.

Male Calves Born 65 50
Summary

Summary of FemEXX Trial Results

All last 3-5 years trial summary proved female sex ratio way higher than control group. FemEXX results are very much comaprable vis a vis to Sexed semen technology with distinct advantage of having trial animals between 1st lactation to 5th Lactation
