“…Cetin et al (1997a) calculated the hatchability to be 62.03% during the hatching period, which produced pheasants at rate of 1♂:5♀. Deeming et al (2011) noticed that pheasants breed at a rate of 1♂:7♀ in open systems and their hatchability was over 70% in the first 5 weeks of a 10-week period, thensimilar to our studythe efficiency declined. Esen et al (2010) calculated the hatchability in their 1-, 2-and 3-year old's, at rate of 1♂:4♀, to be 63.35, 69.68 and 71.45%, respectively.…”

“…It is considered a significant factor that, among the breeding flock, nothing has been done to ensure uniformity (Table 5). Deeming et al (2011) reported early embryo death rates between 4.5 and 5%, and middle to late embryo death rates to be between 15 and 16% in total at the end of the incubation process, which lasted for 10 weeks with the pheasants they bred in an intensive system. Deeming and Wadland (2001) calculated the embryo deaths of the eggs that they produced from pheasants to be at a rate of 1♂:8♀ and 1♂:12♀, by dividing them into 6 groups on specific days (1 to 4, 5 to 8, 9 to 12, 13 to 16, 17 to 20 and 2 1 to 25).…”

Pheasant rearing is rated in three main categories: show and hobby, public interest, and stocking for game birds and edible purposes. The goal of this pheasant breeding station is to put stocking for game birds in their natural habitat, mainly in the Karadeniz region. Contribution to the issues related to incubation in this station and determination of effective reproduction age by setting production period. The aim of this study is to determine how significant performance criteria like egg production, fertility, hatchability and embryonic mortality are, depending on age and on seasonal changes. Our research has been carried out at the Gelemen Pheasant Breeding Station in Samsun. The pheasant breeds that are used on the farm are made up of 114 male and 800 female pheasants (1♂:7♀), of Hungarian and Caucasian genotypes. During the egg-laying period, which lasts for 16 weeks from the end of March (at the age of 45 weeks) to the middle of July (at the age of 60 weeks), egg production was recorded daily and evaluated once a week, and incubation yield was recorded nine times in total. Differences between weeks of age, in terms of egg production, egg and chick weights, fertility rate, incubation yield and embryonic mortality, have been found to be statistically significant. However, hatchability has been found to be statistically insignificant.

“…Deeming et al (2011a,b) observed that both male and female pheasants had better feather condition at the end of the breeding season in pens with visual barriers as compared to controls. Deeming et al (2011b) also showed that, although barriers did not affect the frequency of courtship and mating, they did reduce the frequency of aggressive pecks and chases in pheasants. Fertility was also significantly higher and persisted for longer in the pens with visual barriers as compared to the controls, similar to the findings of Leone and Estevez (2008) in broiler breeders.…”

Environmental enrichment comprises stimuli added to the poultry housing environment to enhance the biological adaptation of the birds and improve their welfare. By promoting species-typical behaviour, it has the potential to reduce the risk of harmful behaviours and health conditions, and to guide birds to use the available resources more uniformly. Environmental enrichment may also promote positive emotional states and enhance the birds’ ability to cope with unpredictable environmental changes. In this chapter, we review environmental enrichment strategies that are relevant to commercial meat poultry production, their benefits in terms of the behaviour and welfare of the birds and their potential for contributing to more efficient and sustainable production models. Potential risks or problems that may arise when environmental enrichment is not appropriately implemented are also discussed, finishing with discussion of current gaps in knowledge and concluding remarks.

“…A higher value of the trait was found in eggs laid by birds reared in aviaries. Deeming et al (2011) reported approximately 5% mortality in pheasant embryos for eggs laid in aviaries, up to day 4 of incubation. On the other hand, in eggs obtained from the aviary housing system, Ipek et al (2006) analyzed a number of dead pheasant embryos throughout the whole period of incubation in great detail.…”

“…Moreover, with the passage of the period of reproduction, a significant decline in the value of this feature was observed only in females kept in aviaries. Deeming et al (2011) analyzed the results of pheasant hatchability for set eggs laid during 10 weeks of reproduction. They reported a higher value for the parameter (69-70%) in comparison with the result obtained in the study for both housing systems.…”

A comparative analysis of reproduction parameters and hatchability results of pheasants raised under two different housing systems (cages and aviaries) was performed. In the first system the pheasants were housed in 420 cages, 3780 from the total were females. In the second housing system, 3200 pheasant hens were placed in eight aviaries, where 50 cocks and 400 hens were kept in each. The following parameters were calculated: laying rate, the percentage of hatching, small and cracked eggs, hatchability from set and fertilized eggs, dead embryos up to day 8 of incubation and, finally, dead embryos after day 8 of incubation as well as unhatched, crippled, and weak chicks. The laying rate for the whole period of reproduction in pheasants kept in cages was significantly higher in comparison with aviaries (59.6 vs 27.2%). A higher (P ≤ 0.05) percentage of small and damaged eggs ( -x = 13.6) was recorded in aviaries. The percentage of dead embryos for eggs derived from aviaries, up to day 8 of incubation, was also significantly higher ( -x = 4.7%). There were no significant differences between the housing systems with respect to the remaining features. The results of the investigation made it possible to conclude that pheasants kept in cages were characterized by a higher laying performance with fewer eggs unsuitable for incubation. A lower mortality of embryos during the incubation process was found in eggs derived from pheasants reared in cages. Although there were no significant differences between the analyzed housing systems in terms of hatchability, a higher laying rate for pheasants kept in cages implies that more chicks could be obtained from every female.
