Effect of Hen Weight on Egg Production and Some Egg Quality Characteristics in Pheasants (Phasianus colchicus)

Effect of different egg storage times on some egg quality characteristics and hatchability of pheasants (Phasianus colchicus)

“…Water loss from the egg or movement of water from albumen to the yolk is the most likely reason this finding. Albumen index values in the present study were greater than reported values (Kırıkçı et al, 2003a(Kırıkçı et al, , 2004Kırıkçı et al, 2005;Günlü et al, 2007). Tilki and Saatçi (2004) found the opposite for partridge eggs even though partridges are in the same family as pheasants.…”

“…The yolk index values were similar to those was determined in the literature (Kırıkçı et al, 2003a(Kırıkçı et al, , 2004(Kırıkçı et al, , 2005Kuzniacka et al, 2005;Günlü et al, 2007). For example, yolk index was reported as 43.19 by Kırıkçı et al (2003a) and 41.76 to 44.29 for eggs from pheasants of various weights by Kırıkçı et al (2004).…”

“…The yolk index values were similar to those was determined in the literature (Kırıkçı et al, 2003a(Kırıkçı et al, , 2004(Kırıkçı et al, , 2005Kuzniacka et al, 2005;Günlü et al, 2007). For example, yolk index was reported as 43.19 by Kırıkçı et al (2003a) and 41.76 to 44.29 for eggs from pheasants of various weights by Kırıkçı et al (2004). Yolk index determined in the present study was also found to be similar to those recorded in partridges by Tilki and Saatçi (2004) for 1, 7, 14, 21, and 28 d storage time at 49.37, 48.77, 48.07, 47.01, 45.87, and The differences between values with different superscript letters in the same column are significant (P < 0.05).…”

“…Although shell weight was significantly different across storage times (P < 0.05), there is no consistent trend. Shell weight was reported as 3.03 g by Tserveni-Gousi and Yannakopoulos (1990), 3.22 g by Kırıkçı et al (2003a), 3.14 to 3.35 g by Kırıkçı et al (2004), 3.21 and 3.17 g, respectively, for brown and green pheasant eggs by Kırıkçı et al (2005), 2.80 to 3.30 g by Kuzniacka et al (2005), and 3.08 to 3.49 by Günlü et al (2007). Kırıkçı et al (2005) found that blue and white pheasant eggs had lesser shell weights at 2.79 and 2.77 g, respectively.…”

“…The shape index of pheasant eggs was determined as approximately 80% in various studies (Tserveni-Gousi and Yannakopoulos, 1990;Kırıkçı et al, 2003aKırıkçı et al, , 2004Kırıkçı et al, , 2005Kuzniacka et al, 2005). Shell weight is affected by egg color and hen age in pheasants (Kuzniacka et al, 2005;Günlü et al, 2007).…”
