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.

An experiment to determine the relationship between egg weight, hatch weight and subsequent body weight of the Japanese quail was conducted. A total of 607 eggs collected over 6 days from an existing flock at the Animal Pavilion of the University of Ilorin were used for the experiment. Eggs were individually numbered, weighed and grouped into small (S) medium (M) and large (L) sized eggs based on the mean and standard deviation of the eggs. Mean egg weight were correlated and regressed with mean hatch weight and subsequent weight. Average egg weights were 10.23± 0.84g, 8.49± 0.72g and 6.94± 0.93g for the large, medium and small group respectively. The result showed relationship between egg weight and hatch weight were positive and highly significant (P < 0.01) with values of 0.973, 0.977 and 0.967 for small, medium and large groups, respectively. Relationship between hatch weights and weekly body weights were also positive and significant (P<0.01) for the medium and large groups only but decreased with age. Linear regression equation showed a significant coefficient of determination for weekly body weight using the values for small, medium and large egg weight values. The results of the study showed that egg weight can be reliably used for estimating body weight in Japanese quail and may be used as criteria for early selection of Japanese quail for body weight.

The aim of the study was to evaluate egg production in three heavy Japanese quail populations created and reared in the Poultry Breeding Unit of the Trakia University – Bulgaria, marked as WG, GG and GL. In the experiments, 160 female birds from populations WG and GG, and 96 female birds from population GL were tested up to the 6th production month. The main egg production traits were controlled. The highest egg production for the period was demonstrated in group GL (79.84±4.46%), followed by group GG (76.33±3.40%) and group WG (72.11±4.16%). Quails from the WG group were outlined with least efficient feed conversion per egg (74.49±1.21 g feed), while those from the GL group: with the most efficient one – 64.93±1.41 g (p<0.01). The highest average egg weight in descending order was observed in the WG group (14.04±0.32 g), GG group (13.65±0.27 g) and GL group (12.79±0.29 g). The Japanese quail populations created and maintained at the Trakia University showed a potentially good egg production for the production type they belonged to, which makes them attractive for use in interline hybridisation schedules, including for production of autosexing stock layers.
