dc.description.abstractIn the present experiment the effects of clutch size on egg production in Japanese quail (Coturnix coturnix japonica) was investigated. In total, 131 six weeks old female quails were kept in individual cages and daily egg productions and egg weights were recorded over a period of six months. At the end of the production period the analyzed phenotypic correlations between clutch numbers, clutch size, pause numbers, pause size, hen-day egg production and egg weight were calculated. The average age at first egg laid and the age at 50% egg production were determined as 45.2 +/- 0.64 and 74.5 +/- 0.89 days, respectively. Clutch lengths ranged between I and 34 days and percentage of clutches consisting of only one egg was 10.3% of whole clutches. In addition, clutch lengths with 1-5 eggs, 6-10 eggs, 11-15 eggs and >16 eggs amounted to 44.4%, 33.1%, 16.4% and 6.09%, respectively. During egg production it was observed that the majority of intervals between clutches (pauses) were one-day periods (70.4%). At the end of the experiment the mean numbers of clutches per hen were determined as 18.8 +/- 0.33 and the mean clutch length was determined as 7.69 +/- 0.17 days. The mean number of laying pauses was 18.4 +/- 0.38 and the mean pause length was 1.40 +/- 0.04 days. A significant negative correlation was determined between numbers of clutches and hen-day egg production of -0.438 (P < 0.01). This indicates that hen-day egg production is higher for lower numbers of clutches. Further significant correlations were calculated for egg weight and numbers of clutches (0.254; P < 0.01), clutch length (-0.303; P < 0.01), number of pauses (0.236; P < 0.01), hen-day egg production (-0.172; P < 0.05).en_US
