Abstract

: This work aimed to study the effects of selenium nanoparticles and nicotinamide in-ovo injection on hatchability and physiological traits of broiler chicks at hatch day. A total of 500 eggs from Arbor Acres breeder hens were weighed and distributed into five treatments with four replicates for each. At day 18 of incubation, eggs of the first group were non-injected and served as control, while the 2 nd group was injected with normal saline at 0.9 % (saline group). But, the 3 rd group was injected with selenium nanoparticles (SeNPs) (20 μg SeNPs/ egg) the 4 th group was injected with nicotinamide (NAM) (300 mM NAM/ egg) and the 5 th group was injected with their mixture (20 μg SeNPs plus 300 mM NAM/ egg). The results showed that chicks of saline and mixture in-ovo injection groups had higher significant weights at hatch compared to all other studied groups. In contrast, eggs of the in-ovo NAM injected group had higher hatch of fertile egg percentage values with insignificant differences with both control and mixture injected groups. The chicks of NAM and mixture in-ovo injected groups had significantly highest WBC values compared to all other studied treatments. The chicks of SeNPs, NAM, and mixture in-ovo injected groups have significantly higher low-density lipoprotein compared to control and saline groups. This suggested that the in-ovo injection with NAM and the mixture groups used in the present study had a considerably positive effect on hatchability percentage, chick weight, relative chick weight, white blood cell count, and blood glucose level and the activity of total antioxidant capacity (TAC). In conclusion, injection of eggs in-ovo of broiler chicks with 300 mM nicotinamide/ egg and mixture between 20 μg SeNPs plus 300 mM NAM/ egg enhanced hatchability and some physiological traits for chicks.
蛋内注射纳米硒和/或烟酰胺对肉鸡某些孵化后性状的影响
本试验旨在研究纳米硒和烟酰胺在蛋内注射对孵化日肉鸡孵化率和生理性状的影响。试验选用500只爱拔益加种鸡,称重后分成5个处理,每个处理4个重复。孵育第18天,第一组不注射卵作为对照,第二组注射0.9%生理盐水(生理盐水组)。第3组注射纳米硒(SeNPs) (20 μg SeNPs/鸡蛋),第4组注射烟酰胺(NAM) (300 mM NAM/鸡蛋),第5组注射两者混合(20 μg SeNPs + 300 mM NAM/鸡蛋)。结果表明:盐水和混合蛋内注射组雏鸡孵化时显著体重高于其他各组。相比之下,在蛋内注射NAM组鸡蛋的孵化可育蛋率值较高,但与对照组和混合注射组差异不显著。与其他处理相比,NAM和混合蛋内注射组的WBC值显著最高。SeNPs、NAM和混合蛋内注射组雏鸡的低密度脂蛋白显著高于对照组和生理盐水组。由此可见,在蛋内注射NAM和本研究使用的混合组对孵化率、鸡重、相对鸡重、白细胞计数、血糖水平和总抗氧化能力(TAC)活性均有显著的正影响。综上所述,在肉仔鸡蛋内注射300 mM烟酰胺/蛋和20 μg SeNPs + 300 mM NAM/蛋的混合物,可提高鸡的孵化率和部分生理性状。
