Sobre IBD

Niniejsze badanie miało na celu zbadanie wpływu iniekcji PGF2α lub GnRH w okresie poporodowym na inwolucję macicy, długość okresu poporodowego, liczbę usług na poczęcie, dni otwarte i odstępy między wycieleniami u krzyżowanych sudańskich krów mlecznych.Wyniki tego eksperymentu wyjaśniły, że wstrzyknięcie GnRH znacząco skraca czas potrzebny na inwolucję macicy, okres poporodowy, dni otwarte i okres między wycieleniami w porównaniu z kontrolą (odpowiednio P < 0,005, p < 0,05, P < 0,001 i P < 0,001). Co więcej, liczba usług na poczęcie uległa znacznej poprawie (P < 0,04).Stwierdzono, że stosowanie PGF2α lub GnRH w pierwszym, drugim lub trzecim tygodniu po porodzie poprawia wydajność reprodukcyjną krzyżowanych krów mlecznych. W ten sposób można wyprodukować jedno cielę na krowę rocznie, jeśli zastosuje się ten system. Jednak pojedyncza iniekcja PGF2α już po 7 dniach nie ma wpływu na powyższe parametry.
