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.

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.

This study aims to determine the correlation between hatching egg weight with egg weight loss and DOC weight of Bangkok male crossbreed chickens with Pelung broodstock. This research uses a unit of automatic digital hatching machines (temperature regulation and automatic turning). The research material is Bangkok rooster chicken, amounting to two tails and four Pelung broilers. The chicken is crossed, and then the eggs are collected to be hatched eggs. This study uses digital camera tools, digital scales, and calculators. The coded eggs are hatched for 21 days. The parameters measured in this study were: Hatching egg weight (grams), egg weight of day 18th hatching, egg weight loss (%) / egg shrinkage, DOC weight, the correlation value between the weight of hatching eggs with egg weight loss, the correlation value between the weight of hatching eggs with the weight of DOC. Data analysis using correlation. The results obtained were the average hatching egg weight of 45.91 ± 3.75 grams, the average of hatching eggs on the 18th day 41.13 ± 3.43 grams, egg weight loss 10.40 ± 0.56%, weight DOC 35.36 ± 3.33 grams, correlation of hatching egg weight to DOC0.98 weight, hatching egg correlation with egg weight loss -0.25. Based on the results of the study,  it can be concluded that the characteristics of Bangkok crossbreed hatching eggs with Pelung brooders are in the normal range.  The correlation of hatching egg weight with very high DOC weight and positively correlated, correlation of hatching egg weight with low egg weight loss and negatively correlated.
