Sažetak

Ova ispitivanja su izvedena na 448 ejakulata dobijenih od 41 nerasta rase poljski landras. Ejakulati su uzimani za analizu u jednomesečnim intervalima u toku perioda 10 meseci. Morfometrijska merenja su vršena u svežim ejakulatima upotrebom mikroskopa. Ejakulati su bili klasifikovani u tri grupe na osnovu koncentracije spermatozoida. U ovoj studiji je napravljen pokušaj da se kod nerastova poljskog landrasa utvrdi korelacija između parametara kvaliteta ejakulata, učestalosti morfoloških alteracija spermatozoida i njihovih morfofometrijskih vrednosti sa koncentracijom spermatozoida. Potrebno je naglasiti da su vrednosti morfometrijskih parametara povezane sa koncentracijom. Spermatozoidi iz koncentrovanijih ejakulata su imali manje glave nego oni iz retkih. Ovo bi moglo da znači da je visoka plodnost nerastova koji daju koncentrovane ejaculate, ne samo rezultat visoke koncenracije, već i činjenice da spermatozoidi imaju manje glave. Najveća zastupljenost morfološki pravilno formiranih spermatozoida je utvrđena u ejakulatima sa koncentracijom od 400 do 500 x103/mm3.
