With Jelto another interesting Jesther son is tested. He is out of the well-known Marconi daughter Aurora from the farm Hol-Stiens from the Netherlands. Jelto sires a very high milk yield with good protein weight. His daughters are uniform, capacity cows with good strength and well-sloped rumps. The feet & legs convince with very good hooves.The highlight of his transmission are his faultless udders. Jelto is recommended for the use on heifers and shows good figures for cell count and fertility.
