Original language name
The egg quality indicators and relationship of shortening and strength of eggshell of three initial laying lines (hybrid moravia bsl)
Original language description
The highest ratio of abnormal eggs was found in both Bar Plymouth Rock lines (BPR A and BPR B) -- 7.5% and 8.3% resp. The lowest ratio was found in lines Rhode Island Red (RIR C) -- 2.1%. The correlations between shortening of egg and total number of eggs were negative. The correlations between shortening and cracks was significant in RIR C rp= -0.46 (P<0.01).The relationships between strength of eggshell and shortening of egg are characterized by positive correlations, significant for BPR B rp= 0.55 (P<0.01). Correlations between strength of eggshell and ratio of eggshell were significantly positive (P<0.01) for all three lines. Negative correlations were found out between strength of eggshell and number cracked eggs (from rp= -0.14 to rp= -0.29) . Negative correlations existed between strength of eggshell and total number of abnormal eggs (from rp= -0.13 to rp= -0.21).
