“…But in the age after 58 week, the fertility and hatchability was decreased. Similar result from Islam et al, (2008 ) highest (P<0.05)hatchability was found in the age group between 31 to 60 weeks (77.99%) followed by 61weeks (75.49%).The same result also observed by the Pramunik (2009) andTuncer et al (2006).…”

The experiment was conducted to determine the effect of artificial insemination (AI) on different production parameter in Hubbard Classic Broiler breeder parent stock. A total number of 300 female and 30 male Hubbard Classic broiler breeder parent stock birds were used as experimental animals and parameter recorded are: Health condition and body weight of birds, % of Production, % Hatchability,% Uniformity, grade A chicks, mortality % , hatching egg % & effect of diluents use, birth weight of day old chick (DOC). Significant variation (p<0.01) was observed in number of hatched birds, % of hatchability, production of total no of Grade A chicks, total number of damaged chicks and average chick weight. In the study, hatchability (%), production (%), growth and puberty weight (g) were significantly higher during post insemination compared to pre insemination stage, where as mortality (%) and uniformity (%) were significantly lower in case of post insemination stage. Body weight and uniformity (%) of birds either both sexes were significantly (p<0.01) different in birds at pre insemination stage compared to the birds at insemination. To be mentioned that body weight of birds was negatively correlated to the uniformity. Finally it could be concluded that AI may be better in all the parameters observed in this study than natural mating. So, AI can be practiced in Hubbard Classic broiler breeder parent stock.

“…The highest fertility rate among the age of hen groups was found in middle aged hens followed by youngest group of hens and the fertility decreased with the increase in hen's age (Othman et al, 2014). Islam et al, (2008) showed that, with groups of breeder hens, the highest hatchability was found in 41 to 60 weeks and lowest in 28 to 40 weeks. There may be a distinct explanation for the higher fertility and hatchability % of eggs from peak production flocks.…”

“…The nonappearance of a significant season effect on most of the traits under consideration may probably be due to that the broiler breeder flocks are reared under partially automated close confinement housing system. The best value of hatchability percentage was observed in winter (78.6) followed by monsoon (76.7) and summer (75.8) (Islam et al, 2008). Jesuyon and Salako (2013) showed that late wet season was most favorable for hatching activities in both Bovan Nera and ISA Brown parent stock compared with the remainder seasons.…”

The present field study was conducted to determine the effects of: 1) 3 types of disinfectants ; 2) storage duration (i.e. from 1 through 6 days); 3) flock production stage (before peak, from 28 to34 weeks and at peak production stages, from 35 to 45 weeks of flock age) and 4) season (i.e. Spring and Winter) on hatchery operation quality of a Cobb broiler breeder flock. Data analyzed was comprised of about five hundred and seventy four thousand (574,000), eggs.Traits studied were percentages of on %overall (Trolley) hatchability along with fertility, clear (infertile) eggs, hatchability (%hatched chicks), %eggs losses (exploded), % Abnormal embryonic positions, %Omphalitis, %pipped eggs in addition to % early and late embryonic mortality of egg tray. The superiority in most traits has been related, generally, with Egg-Washer-Pro and Biosentry-904, followed in most traits by Virkon-S and eventually the control group. Storage period had high significant effects (P< 0.001 or P< 0.0001) on % overall (Trolley) hatchability; % apparent fertility; %infertility; hatched chicks, %late embryonic mortality and % pipped eggs traits. Results revealed generally that most hatchery measurements can be improved by storing fertile eggs for two to four days before being set in incubators. Most characteristics of incubation measurements varied significantly with flock production status (peak effect). All studied traits varied insignificantly with season effect, but % pipped eggs (P< 0.01).

“…Usually, young birds show less broodiness character. Chicken at age of 41-47 weeks may be suitable for selecting broody hens [10] as the medium aged (40-61 weeks) hens give high hatching percentage compared to early and old aged birds [11]. c) Season of broodiness: The incubation season is also important as both the farmers and broody hens prefer to incubate eggs at a particular period of the year.…”

Broodiness and Broody Hen Management During Egg Incubation

Broodiness behavior is usually seen in avian species. This behavior is dominant in wild birds and indigenous poultry compared to modern egg-laying strains. Eggs laid by indigenous chickens are usually hatched by the broody hens. Due to broodiness behavior, the broody hen sits on a clutch of eggs and incubates them to get offspring. Small-scale farmers generally depend on the broody hen to procure chicks. Like an artificial egg incubator, the broody hen controls temperature, humidity, aeration, and turning by herself. The hatchability of broody hen reported seems similar to an artificial egg incubator. The broody hen might be acknowledged as a natural incubator for operational efficiency and effectiveness. Although broodiness is associated with reduced egg production, it contributes a significant role in enhancing the rural poultry population by supplying chicks. Moreover, the loss of egg production due to broodiness can be minimized through management interventions. The importance of broodiness, broody behavior, regulation of broodiness, performances of broody hens, and their management have been discussed in this study.
