“…Stocking density has been shown to influence egg production and performance of broiler breeder hens as higher density produced fewer eggs (Mtileni et al, 2007). In addition, egg storage periods may affect fertility and hatchability in poultry chicken species (Babiker & Musharaf, 2008;Caglayan et al, 2009), and feed restrictions (Sarica et al, 2009) season, flock age and disease-vaccination conditions (Turkyilmaz et al, 2010;Holt et al, 2011) were also found to interact growing and laying performance in chickens. Recent studies have demonstrated that although maternal dietary protein level had no effect on hatchability and growth rate (Kingori et al, 2010), but age (Bekele et al, 2010) and phenotype (Haunshi et al, 2011) affected production performances of laying hens.…”

Production performance and economic efficiencies of broiler of Cobb 500, cockerel of ISA Brown, Fayoumi, and RIR (Rhode Island Red) and Sonali (derived from RIR? × Fayoumi?) available in Rajshahi were investigated. Identical care and management practices were provided to chickens of all genetic groups reared for meat and egg production. Performance of four meat purpose chickens viz., Cobb 500, ISA Brown, Fayoumi and Sonali were evaluated in terms of such important parameters as initial body weight (IBW), 5-wk rearing period (RP), achieved body weight (ABW), feed intake (FI), body weight gain (BWG) and feed conversion ratio (FCR). Performance of three egg purpose chickens viz. Fayoumi, RIR and Sonali included weight of day-old chick (WDOC), growth rate (GR), death rate (DR), fertility (FR), hatchability (HT), first laying age (FLA) and monthly egg production (MEP). Economic efficiency parameters viz., total cost (TC), gross return (GRR), net return (NR) and cost-benefit ratio (CBR) were calculated for both types. In terms of FI, FCR and BWG values, broiler of Cobb 500 was the best preferred and cockerel of ISA Brown the least preferred chicken. Conversely, in terms of the CBR values for meat producers, the cockerel of ISA White (1.58) was the best and the broiler of Cobb 500 (1.15) the worst. Taking the FLA and MEP into account, RIR topped the list (19.1 wks and 23 eggs per month) whereas Cobb 500 ranked at the bottom (25.2 wks and 16 eggs per month). CBR for egg productivity, on the other hand, was highest in Sonali (1.11) followed by RIR and Fayoumi (1.10 each) and Cobb 500 (1.09). As regards the meat productivity, significant correlations existed between TC and NR for all chickens except Sonali, which exhibited a negative correlation between the traits. Negative and non-significant associations prevailed for egg productivity in all the chickens. Although broiler of Cobb 500 was found to be the most popular for meat and RIR for egg, the cockerel of ISA Brown was the chicken that earned the maximum CBR.DOI: http://dx.doi.org/10.3329/ujzru.v31i0.15374Univ. j. zool.

“…Eggs after 1-2 days of storage were characterized by higher values of the white and yolk indices and number of Haugh units than eggs examined in 9th or 10th day of storage. On the other hand, in the investigations carried out on the rock partridge (Alectoris graeca), no significant differences were recorded in the white index and the number of Haugh units when egg quality was analysed after 1-2 and 9-10 days of storage (CAĞLAYAN et al 2009). ŞEKEROĞLU and ALTUNTAŞ (2009), when evaluating eggs (small, medium, large and extralarge) of brown-egg layer hens, reported that yolk and albumen height increased with egg size.…”

Abstract. The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – from 11.51 to 12.50 g and group XL – from 12.51 g. In experiment I, on days: 1, 3, 5, 7 and 10 of storage, the following traits were assessed in 20 eggs from each group: egg weight (g) and yolk and albumen index as well as the number of Haugh units. In experiment II, five hatches were carried out. The total of 480 eggs were incubated in each hatch (120 eggs for each group). On the 15th day of incubation, the eggs were weighed. After hatching, 30 chicks from each group were weighed. Basic hatchability indices were also determined. Eggs with the smallest weight, stored for 1 day, with the smallest yolks were characterized by their highest content contrary to the eggs with the highest weight (the biggest yolks but with their smallest percentage content). In eggs with the higher weight (groups L and XL), a certain increase in weight and proportion (%) of yolk was observed after 3, 5, 7 and 10 days. The highest albumen percentage content was determined in eggs from groups L and XL, whereas in the remaining groups the albumen content was the smallest. With the lengthening of the egg storage, the albumen weight did not undergo significant changes. After one-day storage, the yolk and albumen index as well as Haugh units were slightly higher for eggs of smaller weight than for bigger ones. Eggs from groups S and M were more spherical. Eggs from groups L and XL had smaller weight losses during hatching. Eggs from group L were characterized by the best fertilization, hatchability results and proportion of dead embryos and unhatched chicks. The heaviest chicks were obtained from eggs of the highest weight, while the lightest – from eggs of the smallest weight. The obtained results appear to indicate that Japanese quail eggs of 10.51-12.50 g are the best for hatching.

“…The authors observed that eggs stored for 1 to 2 days had higher values in white and yolk indices and Haugh units than those examined on the 9 to 10th day of storage. On the contrary, in rock partridge (Alectorus graeca), Cağlayan et al (2009) found no significant differences in white indices and Haugh units between eggs analyzed in 1 to 2 days and 9 to 10 days of storage. In Japanese quails, Nowaczewski et al (2010) reported that eggs stored 10 days recorded lower values in yolk and albumen indices than freshly laid eggs.…”

The present study was conducted to determine the external and internal egg quality of Isa Brown (Gallus gallus domesticus) chicken and Japanese quails (Coturnix coturnix japonica) as affected by storage time under room temperature in the hot weather conditions of Nigeria. Parameters evaluated included egg weight, albumen and yolk indices. For each species, a total number of twenty freshly laid eggs was collected and divided into five groups representing different days of storage (0, 7, 14, 21 and 28 days). Storage temperature and relative humidity respectively, are 28.3ºC and 75%. Analyzed results showed that storage time significantly affected egg weight, but has no effect on egg length and width in the two species. Egg weight at day 0 and 7 were higher and superior to 14, 21 and 28 days. Shell thickness in this study had significant decrease in values from day 0 to 28. The decline in this trait due to prolonged storage time was probably due to loss of water as a result of evaporation from internal egg which caused loss of viscosity. With regard to albumen indices, there was a decrease in the values of albumen weight and others with increasing age of eggs in store. Pertaining to internal egg quality, Haugh unit score which measures the freshness and quality of an egg equally recorded a gradual decline from day 0 to 14, while the values fell below standard from day 14. This implies that chicken and quail eggs are not fit for human consumption after 14 days in the hot environment unless stored in refrigerator. Yolk indices such as yolk width and height decreased with advancing age of eggs in the store. But the reverse was the case for yolk weight and ratio which recorded higher values as storage time progressed. As indicated in this study, chicken and quail eggs should not be held under room temperature for more than 14 days during hot season to maintain its freshness and quality.
