JEŘÁBEK, S., ZATLOUKAL, M., STRAKOVÁ, E.: Defective eggs and their relationship to egg yield, weight of eggs and body of hens of five initial laying lines. Czech J. Anim. Sci., 49, 2004, 51 -- 57

Popis výsledku v původním jazyce

We investigated 3985 individually housed hens of five initial laying lines of two breeds, RIR and BPR. The proportion of abnormal eggs out of the eggs laid before the age of 240 days ranged between 7.0% and 9.7%, in dependence on the line. The average number of cracked eggs ranged between 2.5% and 4.4%, double-yolk eggs between 2.2% and 3.0% and shell-less eggs between 2.0% and 2.7%. The correlation between the number of eggs laid at the beginning of the laying period and during the entire period, and the frequency of double-yolk eggs was positive (rp = 0.00 to rp = 0.21) and mostly statistically highly significant (P<0.01). On the other hand, statistically highly significant negative correlations (P<0.01) were found between the number of eggs laid during the entire period and the frequency of cracked eggs, where the correlations in the individual lines ranged between rp = -0.04 and rp = -0.23. Positive correlations, mostly statistically highly significant (P<0.01), were found between
