Organic and inorganic selenium in Aseel chicken diets: Effect on hatching traits

Abstract

A study was conducted to evaluate the effect of dietary selenium (Se) sources (organic and inorganic Se at 0.30 ppm and basal diet at 0 ppm level of supplemented Se) on hatching traits in four varieties of Aseel chicken, Lakha, Mushki, Peshawari, and Mianwali. In total, 84 adult molted hens (50 wk old), 21 from each variety, were randomly assigned to 12 treatment groups in a 3 (Se diets) × 4 (Aseel varieties) factorial arrangement under a randomized complete block design. Each treatment was replicated 7 times with individual hens in each. Settable egg, fertility, hatch of fertile eggs, hatchability, A-grade chick, and embryonic mortality parameters were evaluated. The results indicated that the birds fed an organic Se supplemented diet had greater (P < 0.05) settable eggs, fertility, hatch of fertile eggs, hatchability, and A-grade chicks and reduced embryonic mortality than those fed inorganic or no Se. Among varieties, Mushki had lower (P < 0.05) fertility, hatch of fertile eggs, hatchability, and A-grade chicks than rest of three varieties. Interaction of Se sources and varieties indicated that dietary organic Se supplementation improved (P < 0.05) hatch of fertile eggs in Peshawari and Mianwali, whereas hatchability only in Peshawari variety and reduced embryonic mortality in Mianwali. It was concluded that dietary supplementation of organic Se could be used to improve hatching traits as well as reduce embryonic mortality in native Aseel chicken.

Effects of dietary supplementation of different sources and levels of selenium on the semen quality and reproductive performance in aged broiler breeder roosters

“…However, dietary supplementing 0.4 mg/kg of mineral selenium or zinc-selenomethionine to Cobb broiler breeder hen and rooster from 22 to 53 wk of age did not improved fertility rate ( Urso et al, 2015 ). Genetic, dosage and type of the supplemented Se may affect fertility outcome in poultry ( Khan et al, 2017 ).…”

Effect of Microbiota-Selenoprotein on Meat Selenium Content and Meat Quality of Broiler Chickens

“…Khan et al [ 37 ] revealed that supplementation of Se-enriched probiotic improved breast meat quality and enhanced the antioxidant capacity by increasing GSH-Px and SOD activity with MDA reduction. Also, a significant reduction in breast muscle lipid peroxidation and drip loss was observed when Se was supplemented as a nano-Se form in broiler chickens [ 38 ].…”

Effects of selenium supplementation on the growth performance, slaughter characteristics, and blood biochemistry of naked neck chicken

“…Selenium has been demonstrated to be one of the essential nutrients that birds require for optimum growth and reproduction ( Khan et al, 2017 , 2018 ). It performs a range of activities connected to chicken rearing and production.…”
