“…The significant positive correlations between egg weight and egg width observed in indigenous chickens are consistent with previous reports (Yakubu et al, 2008;Yousif and Eltayeb, 2011;Kgwatalala et al, 2016;Markos et al, 2017). Significant and positive correlation coefficients between egg weight and other external egg quality traits, such as egg width, egg length, and shell weight indicate that selection for higher egg weight in indigenous chickens could result in simultaneous positive improvements of the other traits but might negatively influence the shell ratio of local chicken ecotypes that is negatively correlated with egg weight.…”

Indigenous chickens were evaluated for their egg production, growth performances, and external and internal egg quality parameters across three agro-ecologies. For experiment 540 (180 male and 432 female) chickens were distributed to the three agro-ecologies (lowland, midland, and highland) at their 20 weeks age. Body weight was recorded from each chicken during distribution, 4th week, and 8th week after distribution into pre-selected households. Egg production potential was identified from the indigenous chickens across different agro-ecologies. Moreover, egg quality traits were evaluated from randomly selected 270 (90 from each agroecology) eggs. Egg production of indigenous chickens in the highland was 47.7 which was highly significantly (P = 0.0001) lower number than of midland (54.2) and lowland (51.4). Except for Shell weight, all the external egg quality parameters evaluated were exhibited significant differences across different agro-ecologies. Among the internal egg quality parameters only albumen weight had a significantly (P = 0.007) higher in midland than highland. Most of the variation in egg weight was due to the positive correlation with egg length (69%), and egg width (67%). There was a variation for performance and egg quality traits of indigenous chickens in different agro-ecologies, especially better in midland, which might be resulted from the variation in environment, feed resources availability, and better management followed by households.

“…Naked neck chickens laid heavier eggs with higher mean length and width than the present white leghorn strain at 40 weeks of age [ 9 ]. There were also reports of lower mean values in comparison to the present findings for egg length (54.39±0.11 mm) and width (39.92±0.07 mm) [ 7 ]. The shape index reported under the study (73.53±0.18) falls within the “normal” range of 72-76 [ 10 ] and is lower than the earlier reports [ 8 , 9 , 11 ].…”

Aim:The experiment was carried out to evaluate different external and internal egg quality traits and to figure out their mode of inheritance from a set of hierarchically classified data.Materials and Methods:The data collected from 548 progenies (1 egg from each progeny) of 282 dams mated to 47 sires (1 sire mated to 6 dams) of a White Leghorn flock were used in the present study. Phenotypic means and their standard errors were calculated for all the quality traits. Heritabilities were estimated for these traits separately from “sire,” “dam” and “sire+dam” (full-sib) components of variance using Statistical Package for Social Sciences-17 program.Results:External quality traits such as; egg weight, length, width, shape index, surface area, shell weight, shell thickness, shell ratio, and internal quality traits such as; length, width, height, and weight of albumen and yolk, albumen index, albumen ratio, Haugh unit (H.U.), yolk diameter, yolk index, yolk ratio, and yolk albumen ratio were measured in 548 eggs of the experimental White Leghorn flock. The eggs were found to have optimum weight (57.78±0.20 g), shape index (73.53±0.18) and shell characteristics (6 g, 0.32 mm) as per its genetic potential. Higher values for albumen height (8.41±0.04) mm and H.U. (92.00±0.19) are attributable to the freshness of eggs and proper age of hens. Heritability estimates from “sire” component of variance were higher than “dam” and “sire+dam” components for the traits like egg weight, length, width, shape index, surface area, albumen width, albumen index, H.U., yolk width, yolk height, yolk weight, and yolk index whereas for rest of the traits the values estimated from “dam” component were higher. Estimates from “sire+dam” component were intermediate to the estimates derived from “sire” and “dam” components.Conclusion:The heritability estimates from different egg quality traits were moderate to high. Since most of the traits have high heritability values, these traits can be improved by mass selection.

“…Yeasmin and Howlider (1998) and Yeasmin et al (2003) where they found hen day egg production of IDC were 33.50 and 43.26%, respectively. Rate of lay of native dwarf chicken of Kenya, Benin and Sudan was 36, 33 and 39.32 % respectively reported by Njenga (2005), Dakpogan et al (2012) and Yousif and Eltayeb (2011), respectively. Findings of these above studies support the present investigation.…”

The study was conducted to investigate the phenotypic features, morphometry and production potentialities of indigenous dwarf chicken (IDC) of Bangladesh under intensive management condition. A total of 48 females and 12 males were collected from different districts and the experiment was performed at BAU Poultry farm for a period of 75 weeks. The predominant plumage and skin color were black and white, respectively. The average shank length, shank circumference and live weight (28 weeks) in adult males and females were 7.5 and 4.69 cm, 6.28 and 3.69 cm, and 1.77±0.38 and 1.10±0.077 kg, respectively. The reduction of live weight for dwarf male and female chickens relative to their normal shanked counterparts (NSC) at same age was 12.91 and 16.91%, respectively. Hen day egg production, average egg weight, average feed intake and FCR (feed conversion ratio) of IDC were recorded 37.43%, 38.25 g, 69.57g and 4.58, respectively. The average age and weight at sexual maturity were recorded as 166.53 days and 1093 g, respectively. IDC consumed 11.13% less feed than NSC during 1-20 weeks. Survivability of IDC up to 0-8, 1-23 and 24-75 weeks of age were found 97.25, 94.90 and 95.24%, respectively. The study reveal that IDC had relatively lower adult weight and consumed less feed without affecting egg production compared to NSC under intensive management condition and could be exploited its potentiality for development of mini layer under semi-scavenging system of Bangladesh.Bang.
