Cocks and pullets from each of 4 genotypes; Redbro (RbRb), Naked neck (NaNa), Redbro dwarf (Rbdw) and Naked neck dwarf (Nadw) were crossed reciprocally for egg production trial. Egg quality (egg weight, egg diameter, egg length, shell thickness, membrane thickness, membrane weight, shell weight, % of shell, yolk color score, albumen diameter, albumen height, yolk diameter and yolk weight) were compared among 4 genotypes. Daily feed intakes, almost related to respected body size were reduced in Rbdw and Nadw hens by 7.41 and 19.89% than in normal sized RbRb hens. The feed conversion and hen day egg production were highest in Rbdw, intermediate in RbRb and Nadw and lowest in NaNa. Naked neck (Na) and dwarf genotypes had favorable effect on egg fertility and hatchability. Parents in both Na and dw inheritance had favorable shell thickness, shell membrane weight (%), albumen height and diameter, yolk height and diameter, albumen weight and albumen weight (%) and yolk weight, while NaNa had highest yolk weight (%). Both egg weight and chick weight percent were highest in RbRb x

Effect of pasteurization of shell egg on its quality characteristics under ambient storage

2010

Three thermal processes viz. dry (55°C, 2 h), moist (57°C, 5 min) and microwave (power 9, 20 sec) were studied to determine their efficacy for the pasteurization of intact chicken eggs based on the extent of inactivation of artificially inoculated Salmonella typhimurium (ST) in the yolk of shell eggs and alteration in albumen protein solubility (APS). Moist heat treatment was superior to others as it brought about 2 log cfu/ml reduction of inoculated ST in much less time than dry heating but changes in APS were not significant. Subsequent quality evaluation of normal (uninoculated) eggs subjected to moist heat pasteurization during 15 days of ambient (35°C, 36% RH) (35 ± 0.5°C, 36 ± 2% RH)storage revealed no significant effect on percent loss in egg weight, albumen pH, viscosity of albumen and yolk and thiobarbituric acid values between pasteurized and unpasteurized eggs. Pasteurization had no adverse effect on foam volume and foam stability of albumen during storage in comparison to those of raw eggs. Naturally occurring aerobic mesophilic bacteria, coliforms, staphylococci, yeast and moulds on the egg shell surface and in egg contents got markedly reduced by pasteurization of shell eggs and their multiplication also retarded during storage. Both pasteurized and raw eggs remained fairly acceptable sensorily up to 10 days of storage at ambient conditions.
