Egg quality, geometry and hatching traits of indigenous Aseel as influenced by organic and inorganic selenium supplementation

Abstract

This study was conducted to evaluate the impact of selenium sources on egg and hatching traits of native Aseel chicken. Selenium-treated 21-weeks-aged 84 pullets and 12 cockerels from Lakha, Mushki, Peshaweri and Mianwali varieties (21 pullets and 3 cockerels per variety) were divided into three treatment groups A, B and C (7 pullets and 1 cockerel per group). Group A and B were experimental and C was control. Ration for group A was included 0.3 mg/kg Se-yeast, B was included 0.3 mg/kg sodium selenite and C with No selenium. Se-yeast supplementation presented increased egg weight, shell thickness, yolk index, Haugh units; enhanced egg length, breadth, volume, shape index and surface area; decreased dead germ%, dead in shell%, clear egg% and enhanced hatchability%, the hatch of fertile% and chick weight. Present study concluded that Se-yeast is a superior supplement in improving egg quality, geometry and hatching features of indigenous Aseel varieties.

Organic and inorganic selenium in poultry: A review

“…In contrast, no significant (P>0.05) impact of Se was found on final body weight of broilers (Vara et al, 2007;Yoon et al, 2007) Production performance and selenium sources: In a study, it was demonstrated that reproductive traits were improved with the inclusion of Se, while Sel-Plex supplementation improved sperm survival in the oviduct, as well as the production of more settable eggs (Robert et al, 2008). Eggs from breeder hens fed organic Se source had greater Se content than those treated with an inorganic source (Leeson et al, 2008;Zia et al, 2016a). A significant difference was observed in eggs, tissues and hatchability in the Se treated birds than the birds maintained on control diet (Brennan et al, 2011).…”

“…However, some researchers presented a different point of view and reported no correlation between Se and egg weight (Pavlovic et al, 2009). Variation in egg mass is linked with the supplementation of Se forms in the diet as it is evident from certain reports that the inclusion of SY supplementation had significantly improved the egg mass in laying hens (Gjorgovska et al, 2012;Zia et al, 2016a). Many other studies, likewise, showed positive or no effect of different Se forms on FCR/ dozen or FCR/kg egg mass in poultry.…”

“…Many other studies, likewise, showed positive or no effect of different Se forms on FCR/ dozen or FCR/kg egg mass in poultry. Literature demonstrated that SY supplementation in laying hens improved FCR/dozen (Arpasova et al, 2009;Zia et al, 2016a) and also FCR/kg egg mass (Zia et al, 2016a) compared to the hens fed control diet. Improved FCR/dozen has also been reported due to the inclusion of Se regardless of the source (Pan et al, 2011).…”

“…Many research workers demonstrated significantly positive results due to the inclusion of organic sources of Se (Zia et al, 2016a), while the other reported negative or no influences of Se addition, like, Utterback et al (2005) in a study reported that organic Se fed laying hens produced more eggs. Similarly, it was also reported that the Haugh Units (HU) in the hens received Se supplemented diets were improved (Hanafy et al, 2009).…”

Effect of in-Ovo Nano-Selenium Injection on Hatchability, Thyroid Hormones and Histological Changes of Improved Baladi Chickens

“…The degree of response to in ovo feeding may depend on genetics, egg size, breeder hen age, and incubation conditions, site of injection and doses (Uni and Ferket ,2003), however Some researchers who demonstrated that selenium sources help in increasing egg production traits as well as hatchability (Attia et al., 2010;Canogullari et al, 2010;Waseem et al, 2016).…”
