Abstract


The associative analysis of the potassium phenotypes with the quantitativeproduction traits in adult sheep of the Botoşani Karakul breed pointed out theproduction superiority of the HK phenotype in rams concerning the both bodyweight and wool production. The ewes with HK phenotype are slightly moreproductive than the LK ewes concerning the wool production. The productionsuperiority of the LK phenotype was found in females for body weight and totalmilk quantity. Statistically, the difference values of the quantitative productionsbetween the two potassium phenotypes are very close to the 5% significancethreshold in the adult rams and insignificant in the adult ewes. The utilization ofthe kalium system in sheep breeding of the Botoşani Karakul breed forquantitative productions must be made with accuracy because the association ofthe LK phenotype with the qualitative features of the lamb pelts and with thehealth status is better than with the HK phenotype.
