“…On a day old, a clear difference in chick weight was observed in the current study; however, its direct impact in final body weight is unknown because chicks are normally slaughtered from 42 to 56 days. The LBDOC had a lower body weight on day 1, indicating a need for careful grading and selection of eggs for hatching being cognizance of management procedures that optimize egg size for incubation [14].…”

“…The length of the shank was measured from the tip of the shank to the mid-portion between the feet using the Vernier caliper. The navel score was also assessed using the Tona score for the following parameters: Navel strings, navel buttons, opened navel, closed navel, leaky navel, and unhealed navel [14]. If the navel was completely closed and clean, it was scored 1 for navel quality.…”

Background and Aim: The quality of day-old chicks is a cornerstone to successful poultry production. Chicks with a poor quality start slowly in the field and may have high feed intake, poor growth rate, and poor feed conversion ratio. The current study aimed to assess chick quality challenges encountered from day-old chicks hatched in most commercial hatcheries in Ghana. Materials and Methods: A total of 300 day-old chicks each were obtained from commercial hatcheries in Ghana and Europe. The chicks were labeled as locally hatched broiler day-old chicks (LBDOC) and foreign hatched broiler day-old chicks (FBDOC), respectively. Chicks were reared and monitored from day old to 21 days post-hatch. Sample of chicks (n=25) from each hatchery was euthanized weekly at 1, 7, 14, and 21 days and blood samples collected for analysis. The parameters measured included physical, hematological, immunological, histological, and bacteriological characteristics. All data were analyzed by SAS Proc GLM at p<0.05. Results: The live weight of chicks was higher in FBDOC compared to LBDOC on the 1st day. The chick length and shank length of FBDOC were longer than the LBDOC. The 7-day chick mortality was 6% in LBDOC as compared to 1.5% in FBDOC. The LBDOC also had a higher wet and dry residual yolk sac percentages as well as higher residual yolk sac fluid volume than the FBDOC. The rate of yolk sac disappearance of the FBDOC was higher than the LBDOC. More than half of the LBDOC had developed navel strings and leaky navel compared to FBDOC. The LBDOC recorded Escherichia coli, Proteus, Streptococcus spp., and Gram-negative bacteria in the residual yolk sac isolated through the 21 days while FBDOC recorded E. coli, Proteus, and Gram-negative bacteria. The intestinal villi count, lengths, width, and surface area were all not significantly different. The blood monocyte levels appeared higher in FBDOC than LBDOC, which give evidence of higher immunity in FBDOC than LBDOC. Conclusion: The results indicate a challenging situation in maintaining the quality of locally hatched broiler day-old-chicks compared to foreign hatched broiler-day-old-chicks. The study demonstrates that chick quality impact goes beyond the physical characteristics of chick weight and chick length, and the higher performance of FBDOC may be influenced by compliance with international hatchery standards and vaccination protocols.

“…The differences in egg length might be due to variability in genotypes and environmental conditions. Rajaravindra et al (2015) found that the egg length of synthetic coloured broiler female line chickens was 5.57 cm. In current study, egg width observed in Aseel and Kadaknath chicken was 3.85 and 3.79 cm, respectively.…”

Egg quality parameters are very crucial for the egg industry as egg configuration affects grading, price, hatchability, chick weight, and consumer preference. Current study was undertaken to assess and compare the egg quality parameters in 2 important Indian breeds Aseel and Kadaknath reared under backyard system. Different parameters of external and internal egg quality were measured. Biochemical parameters of egg yolk estimated were egg yolk cholesterol, high density lipoprotein ( HDL ), low density lipoprotein ( LDL ), and triacylglycerol. Means for external characters of Aseel eggs viz., egg weight, egg length, egg width, shape index, shell weight, shell thickness, and shell ratio were 41.7 g, 5.16 cm, 3.85 cm, 74.75%, 4.65 g, 0.35 mm, and 11.23%, and corresponding values for Kadaknath eggs were 40.59 g, 5.13 cm, 3.79 cm, 74.02%, 4.28 g, 0.34 mm, and 10.61%, respectively. Average albumin length, width, height, and albumin index were 83.73 mm, 65.4 mm, 6.02 mm, and 9.26% for Aseel eggs and 82.27 mm, 64.80 mm, 5.52 mm and 8.52% for Kadaknath eggs, respectively. Mean values for yolk length, width, height and yolk index were 43.32 mm, 40.10 mm, 15.30 mm, and 38.30% in Aseel and 42.15 mm, 38.97 mm, 14.26 mm and 36.66% in Kadaknath breed, respectively. Mean values for egg yolk cholesterol, HDL, LDL, and triacylglycerol were estimated as 9.38, 1.74, 0.17, and 1.94 mg/g in Aseel eggs and 8.38, 1.84, 0.11, and 1.76 mg/g in Kadaknath eggs, respectively. Biochemical analysis revealed that egg yolk quality of Kadaknath eggs was comparatively better than Aseel eggs.

“…The quality of an egg affects how it is acceptable to the nal consumer. It also predicts its price for both hatching and table eggs (Stadelman, 1977;Rajaravindra et al, 2015). This is in uenced by several factors one of which is the genotype of the bird.…”

A study was conducted on the effect of chicken genotypes and gene polymorphism of Insulin like Growth Factor-1 (IGFI) on reproductive and egg quality traits in five chicken genotype. A total of 250 chicken comprising 150 FUNAAB-Alpha (50 Normal feather, 50 Naked neck and 50 Frizzle feather), 50 Kuroiler and 50 Sasso were used for this experiment. The chicks were generated through artificial insemination and were raised to maturity on deep litter system. At point of lay, 30 hens per genotype were selected and transferred into a battery cage of one unit per bird to monitor their reproductive performance. Data were collected on the following at first lay; body weight of the bird (WOBAFL), egg weight (WOEAFL) and age (AAFL). For the egg quality traits, a total of 30 eggs for each genotype was collected, with the following parameters: egg (weight, length, and width), shape index, shell thickness, albumen (height, weight), yolk weight, ration of shell, yolk and albumen, and haugh unit was measured. All collected data was subject to analysis of variance using a completely randomized design, of which genotype was the interest factor. At 16 weeks, 1ml of blood was collected from each hen and extraction of genomic DNA from the blood was done. PCR was conducted using the pair of primer and condition as described by Nagaraga, et al. (2000). The PCR amplicons were digested using PstI restriction enzymes following the manufacturer’s procedure. The resulting fragments were analyzed using GenAnalyzer. GenAlEx 6.502 was used for the genetic diversity of the IGFI locus. Data for the association studies was subject to the PROC GLM of SAS 9.2. Results showed the chicken genotypes significantly (P < 0.05) affect all the egg-quality traits except the shell weight, yolk ratio and albumen ratio. The IGFI gene polymorphism had no significant effect (P > 0.05) on egg quality traits except the egg length and egg width were seen to be significantly (P < 0.05) affected. The reproductive parameters of the chickens where significantly (P < 0.05) affected by their genotypes except for the age of the bird at first lay (AAFL). IGFI gene polymorphism had no significant effect (P > 0.05) on the reproductive performance except for the WOEAFL.
