“…But our experiment results are in disagreement with the finding of Koppenol et al [4] , who reported that supplementation of broiler breed-ers' diet with DHA and EPA does not have significant effect on incubation parameters (p>0.05). Also Pirsarayi et al [21] suggested that adding of different levels of tallow in broiler breeders' diet did not have a significant effect on livability, fertility, and hatchability. It was also reported that laying quails' diet containing flax seed oil could improve the productive traits and this might be attributed to hormone metabolism regulation, mainly estrogen [22].…”

The present trial was conducted to determine the influence of different dietary fatty acid (omega-3 and omega-6) sources on reproductive performance of female broiler breeders and growth performance and carcass traits of their progeny. Methods: Two hundred and twenty, 25 weeks old Ross-308 male (20) and female (200) broiler breeders were used in the experiment for the period of 6 weeks. All birds were randomly divided into four dietary treatments (containing 2% soybean oil, 2% sunflower oil, 2% flaxseed oil, and 2% fish oil) each with five replicates of one male and ten females. Throughout this experiment hatching performance of broiler breeders, progeny growth performance and carcass parameters were recorded. Results: The results showed that the inclusion of different fatty acid sources in female broiler breeders diet had no significant effects (p>0.05) on number of fertile eggs, post-hatch mortality, and fertility rate. The soybean oil supplemented group had significantly (p<0.05) higher late embryonic mortality compared to other three treatments. Conclusion:It was concluded that inclusion of 2% of different sources of omega-3 and omega-6 fatty acids (especially 2% flax seed oil) in broiler breeders' diet can reduce late embryonic mortality. The other reproductive characteristics of parents and growth and carcass characteristics of progeny remained unaltered by dietary sources of omega-3 and omega-6 fatty acids.

“…These results were in agreement with those obtained by other researchers. (An et al (2010), Ansari Pirsaraei et al (2011), Al-Daraji et al 2010 reported that adding of different omega-3 and omega-6 fatty acids source in broiler breeders and layer quails' diets have a significant effect on egg weight, egg yolk weight, egg shell weight, egg albumen and egg yolk weights, yolk index, and egg yolk colour. However, these results were in disagreement with other studies.…”

The present study was conducted to evaluate the effect of different dietary oil sources (omega-3 and omega-6 fatty acid) in female broiler breeders’ diets on laying performance, egg quality and yolk fatty acids composition. Ross-308 breeders (220; 25 weeks old) were used in this experiment for 6 weeks. Birds were placed in a complete randomized design with 4 dietary treatments (containing 2% soybean oil, 2% sunflower oil, 2% flaxseed oil, and 2% fish oil) and 5 replications containing 1 male + 10 females in each pen having a similar body weight (3,424 g) and egg production (86%). Results indicated that different sources of dietary oil had no significant effect on body weight gain, feed conversion ratio, and egg production but had a significant effect on egg weight. Also feeding the diets containing 2% of different fatty acids had a significant effect on some egg quality parameters and egg yolk fatty acids composition. It was concluded that inclusion of 2% flaxseed oil can improve laying performance, egg quality, and egg yolk fatty acids composition parameters in broiler breeders.

“…With advancing breeder age, egg production rate decreased (Tumova and Gouus, 2012), and egg number also decreased (Rayan et al, (2013) .While egg weight, egg volume and surface area were increased with increasing of the hen's age ( El-Sheikh et al, 2014) . Tona et al, (2004) reported that the weight of 18 d old embryo increased with parental age .Eggs from older hen breeder characterized by higher yolk weight and lower white weight on average when compared with hen at the onset of egg laying, in addition to quality of egg yolk deteriorates as the reproductive season of broiler breeder progress (Pirsaraei et al, (2011). Moreover, albumin characteristics including (albumin index and Haugh unit) and egg shell traits including (weight and thickness) deteriorated as hen aged (Akyrek and Okur, 2009).…”

This study was conducted to investigate how ducks age (Dumyati strain) could affect on some productive traits, egg quality and performance of their offspring. Egg number, egg weight egg mass, Egg production % ,feed consumption and feed conversion to egg was investigated during three periods at (24-32)wk ,(32-40) wk and (40-48) wk. While 30 eggs were collected for determination egg quality at 4 different ages (24 ,32 ,40,48) wk old including (egg weight, egg shape index % (ESI) , shell % and thickness , albumin % ,Haugh unit (HU ) ,yolk % , yolk index and yolk color and shell % and thickness, while a total of 2016 eggs were set in the incubator (504 egg /age ) at the same intervals to determine egg hatchability traits. After complete hatching, (30) duckling-one day old-from each age weighed (initial body weight) and raised for 10 wk old through this period body weight (BW) ,body weight gain (BWG) ,feed consumption (F.C) and feed conversion ratio (FCR) were recorded bi-weekly. The Results of this investigation revealed that, egg production % and egg number significantly decreased with age, while egg weight significantly increased .but egg mass and FCR during 3 different periods didn't show any significant difference. Some egg traits (egg weight, ESI%, yolk % and shell thickness) were significantly increased with advancing ducks age. However, albumin proportion significantly decreased as the productive season progress, but shell % didn't show any significant difference between different ages. HU and yolk index show deterioration with age.Fertility % of eggs significantly increased with age advancing, While early mortality % was significantly higher at the begging of laying season (24 wk old), also total embryonic mortality% showed significant increase in eggs from young ducks breeder, however hatchability of total egg % didn't show any significant difference. Ducklings weight at hatch showed a significant increase with age, but this did not reflect on final body weight or BWG, which significantly decreased with age. Older breeder (48) wk old showed the lowest F.C and 40 wk old breeders had the lowest FCR. No-doubt that age of ducks in this study had a clear effect on some productive traits, egg traits and somewhat performance of offspring. Although of that we can't ignore environmental temperature changes with aging of ducks flock.
