 note = {ハイセックス鶏よりえた506個の鶏卵について卵殼諸形質を測定するとともに, 産卵記録より2連産(C_1∿C_2)から6連産(C_1∿C_6)に分け, 連産(クラッチ)の長さと卵殼諸形質の関係を比較検討した。クラッチ内の第1卵(C_1)はすべて午前中に, 最終卵(C_t)はすべて午後に産卵した。また, クラッチの長いものほどその最終卵は午後遅く産卵した。卵重と卵殼表面積はクラッチが長くなるにつれて小さくなる傾向がみられた。卵殼形質はすべてC_1∿C_2からC_1∿C_3で低下した。そして, C_1∿C_3からC_1∿C_6にかけて卵殼重比, 鶏卵比重, 卵殼の厚さ, SWUSAはクラッチが長くなるにしたがって増加する傾向がみられたが, 卵殼破壊強度と卵殼重の変化はわずかであった。, Experiment were conducted to determine the relationship between egg shell qualities and length of egg-laying clutches (C_1∿C_2 to C_1∿C_6) in hens. Oviposition times of all C_1 (the 1st eggs in clutches) were in the morning and those of C_t (the terminal eggs) were in the afternoon. The terminal eggs were laid later in the afternoon as length of clutches increased. Egg shell qualities of C_t were better than those of C_1. Shell qualities of C_1∿C_2 were also better than those of C_1∿C_3. In comparison of C_1∿C_3 to C_1∿C_6,egg weight and surface area of egg were decreased, but egg specific gravity, percent of shell weight, shell thickness and SWUSA were increased as length of clutches increased. However, egg shell breaking strength and shell weight were little affcted by length of clutches. These results suggest that differences on egg shell qualities observed among clutches of different length and between C_1 and C_t in a clutch is due to the oviposition times and the intervals from C_t to C_1.},
