The study investigated the effect of moisture loss on the Hatchability of chicken, Duck and Quail eggs. A total of 480 eggs; 120 from Rhode Island Red (RIR) chicken, 60 from Zending duck and 300 from Japanese quail were collected and set in the same incubator with 3 replications to compare hatchability results among the species. Moisture loss percentage was highest (P<0.01) in quail eggs (16.19%), intermediate in chicken eggs (7.76%) and lowest in duck eggs (7.24%). Among 3 genotypes, at all (0, 7 and 14 days) ages, eggs weight was highest (p<0.01) in Zending duck (60.50g), intermediate in RIR chicken (59.188) and lowest in quail (9.55g). Egg weight loss at 7 and 14 days of incubation were highest in quail, intermediate in chicken and lowest in duck. There was no appreciable differences of hatchability on set eggs and fertile eggs among species (p>0.05). Apparently, the hatchability on fertile eggs was similar and higher in chicken (58.3%) and quail (58.9%) and slightly lower in duck (53.7%). However, hatchability on set eggs was highest in quail (58.3%) intermediate in chicken (43.3%) and lowest in duck (40.7%). Chick weight at hatchings was highest (p<0.01) in duck (37.55g), intermediate in chicken (34.56g) and lowest in quail (5.61 g). Chick weight as per cent of egg weight was found highest (p<0.01) in duck (62.07%), intermediate in chicken (58.40%) and lowest in quail (54.24%). There were some relations among the different hatchability results depending on species. There were marked variations in moisture effect among the species. It was clear that hatchability not only affected by species but moisture loss also played an important role on hatchability. It was concluded that under similar environment, hatchability on fertile eggs were similar and higher in quail and chicken and lower in duck. But hatchability on set eggs was highest in quail, intermediate in chicken and lowest in duck. It imply that some losses of moisture with various level may be necessary to enhance egg hatchability is required to support hatching results in different species of poultry.J. Environ.

A total of three hundred (300) Japanese quail eggs were used to study the effect of oviposition time and egg weight on hatchability and post-hatch performance. The eggs were grouped into two (2) of 150 eggs based on the oviposition time of Morning and Afternoon. The eggs in each group (150) were further sub-grouped based on the egg weights of 8 to10 grams designated as small sized and 10.1 to 12 grams designated as big size in a 2 x 2 factorial design trial of 4 treatments. Each treatment had seventy five (75) eggs each with three replicates. The four treatments groups were; Big Morning, Small Morning, Big Afternoon, Small Afternoon. Each treatment group was replicated three times with each replicates consisting of twenty-five (25) eggs. Hatchability parameters were determined during incubation period of 18 days. The quail chicks were fed ad-libitum and the post- hatch performance was studied for eight (8) weeks. The data generated were subjected to a one-way analysis of variance. Oviposition time and size of the egg significantly (p<0.05) affected the average hatch weight. The effect of interaction of oviposition time and egg size on post-hatch performance did not have any significant (p>0.05) influence. Oviposition time had a positive correlation (p<0.05) with egg weight, egg weight loss, percent egg weight loss and fertility percentage but negatively correlated with average hatch weight and hatchability percentage. Meanwhile egg size had a positive significant (p<0.01) correlation with average hatch weight. It was concluded that eggs ranging between 10.1 to 12 grams will produce higher hatch weight. However, setting of Japanese quail eggs ranging between 8 to 12 grams irrespective of oviposition time could not affect post-hatch performance of the chicks.

Abstract The present study investigated the effect of the type of alternative housing system, and genotype and age of laying hens on physical traits of egg shell and contents. It was demonstrated that alternative housing system type influenced egg weight and shape, and eggshell color and yolk color intensity. Eggs from free-range system were heavier and were characterized by more intense yolk color. No effect of alternative housing system type on albumen height, value of Haugh units (HU value) and presence of meat and blood spots was noted. Hen genotype had a significant effect on egg weight and eggshell color intensity in each of the alternative housing systems tested in this study. Hy-line Brown hens laid heavier eggs than hens of native breeds. Genotype was also observed to affect egg content traits (albumen height, HU values and presence of meat and blood spots). Independently of the type of alternative housing system, most blood and meat spots were noted in eggs of hens laying brown-shelled eggs, i.e. R-11 and Hy-line Brown layers. Laying hen age significantly impacted on egg weight, yolk percentage, eggshell traits (color intensity, weight, thickness and strength) and egg content traits (HU value, yolk weight and color intensity, presence of meat and blood spots). Older hens laid heavier eggs with a greater yolk percentage but with thinner eggshell.

AbstractThe aim of the study was to analyze eggshell temperature, embryo viability, and hatchability parameters of broiler breeders at different ages (26-30, 31-35, 36-40, 41-45, and 46-64 weeks). A total of 33,150 eggs from Ross 308 broiler breeders collected from commercial flocks were used to analyze the following: egg weight and egg weight loss during 18 days of incubation; eggshell temperature controlled on days 3, 14, and 18 of incubation; number of infertile eggs including eggs with dead embryos at early stages of development, that is, in the oviduct or after oviposition; the total percentage of embryonic mortality and the percentage of embryonic mortality at different times of incubation; unhatched, dead after hatching, and culled chicks as well as hatchability percentage from fertilized eggs. The hatchability results of Ross 308 broiler breeders were high from the beginning of reproductive season till the 40th week. However, the study failed to reveal any relationships between hatchability and the egg weight, average temperature of the shell, and egg weight loss during incubation period. The oldest hens, over 45 weeks of age, had the highest mortality of chicks and the greatest share of unhatched chicks.
