Association of ewe’s age, premating weight on litter size and birth weight of lambs

РЕЗЮМЕ SUMMARY Целта на изследването е да проследи влиянието на възрастта и теглото преди заплождане на овце от порода "Мис" върху живото тегло при раждане на агнетата, типа на раждане, пола и взаимодействието между тях. В проучването са изследвани 70 овце от порода "Мис" и поколението им от агнета F1 (получено от кръстоска на "Мис" х "Ил дьо Франс"). Данните за възрастта преди заплождане на овцете (PMA), тегло преди заплождане на овцете (PMW), живо тегло на агнета при раждане (LBW), тип на раждане (BT), пол на агнетата са събрани от 122 агнета. The aim was to examine the effect of premating age, premating weight of ewes Mis sheep breed on lamb’s birth weight, birth type, gender and the interaction between subject effects. 70 ewes of Mis breed of sheep and their F1 generation lambs produced (Mis x Ile de France) were used in the evaluation.
