主 题：Duck egg storage period quality.
摘 要：The present study was conducted in each 20 eggs stored at 65 °F with 75% relative humidity, for a period of 5 weeks （T-I） 4 weeks （T-2）, 3 weeks （T-3）, 2 weeks （T-4） and 1 week （T-5） with broad end up. The external qualities of eggs like egg weight, length, width and volume were measured. After recording the external qualities the eggs were broken on a glass plate for studying the internal qualities. Storage period had no statistically significant effect on egg weight （g）, egg volume （%）, shell thickness （mm）, shell weight （g） and shell percentage. Egg weight values determined in this present study was between 61.10 and 64.91 g. The egg volume （%）, egg shell thickness （mm）, shell weight （g） and shell percentage for different storage periods were 87.46 and 98.52, 0.28 and 0.34 5.29 and 5.98; and 8.16 and 9.44 respectively. Yolk weight （g）, yolk percentage and albumen percentage was significantly affected （P 〈 0.01） by storage period and the values ranging between 32.20 and 36.40, 48.59 and 58.53 and 32.01 and 43.24 respectively. Storage period had no statistically significant effects on egg shape index and specific gravity. The storage periods on yolk index, yolk colour, albumen index and Haugh unit were statistically significant （P 〈 0.01）. Yolk index value decreased significantly when storage period was lengthened. This study concluded that yolk index, yolk colour, albumen index, albumen percentage and Haugh unit were decreased with increase in storage time.
