Relations among ewes? nutritional status at mating and their subsequent reproductive performance
Original language description
The aim of study was to determine relations among ewe?s live weight (LW, kg), body condition (BCS) or backfat thickness (BT, mm) at mating, and lambing rate (LR, %), litter size (LS, lambs) or total litter weight at birth (TLWB, kg) by correlation analysis. The number of 608 Suffolk ewes bred in 4 flocks was observed during a 2 year period. Ewes were weighed and their BCS or BT was evaluated subjectively or by ultrasound at the beginning of the mating period. Directly after lambing, the lambs (n = 930)were weighed and basic reproductive traits were assessed: LR, LS and TLWB. Statistical analysis was performed using SAS 9.3., CORR procedure. LW was correlated with all the reproductive traits (r = 0.211 to 0.247; p < 0.01). BCS did not correspond significantly to LR or LS traits, but it correlated signifi- cantly to TLWB (r = 0.101; p < 0.05). There was no significant correlation between BT and LR, while significant correlations (p < 0.01) were detected between BT and LS (r = 0.125) as
