Effect of in Ovo injection with Nano- Selenium or Nano- Zinc on Post-Hatch Growth Performance and Physiological Traits of Broiler Chicks

Abstract

The current study was aimed to investigate the effect of in ovo injection with Nano-selenium or Nanozinc on post-hatch growth performance and physiological traits of broiler chicks under heat stress. Four hundred fertile broiler eggs from cobb500™ flock were randomly divided into four treatments (100 eggs each). First was normally without injection (control), second was injected with 15 ppm Nano-Selenium (SENPs) /egg, third treatment was injected by 15 ppm Nano-Zinc (ZnNPs)/egg and fourth treatment was injected with phosphate buffered saline (PBs) 15 ppm /egg. To study the post-hatch performance, A total number of 240 one day-old chicks were randomly distributed into 4 equal experimental treatments of 60 chicks each. Every treatment was sub-divided into three replicates (20 chicks/ each), were at lasted 5weeks. Results obtained could be summarized as follows: Nano-selenium explained higher chick's weight at hatch, chick's weight to egg weight ratio and hatchability % than all other treatments. At first week of age, the body weight (BW) in the nano-selenium treatment increased than the untreated (control) treatment, although the gastrointestinal tract weight was 0.44 % and the intestine weight was 0.8 %, this is explained by an augmentation in the length of both the length of the small intestine and the gastrointestinal tract by 12 % at 7 day of age. The highest live body weight and body weight gain and the best-feed conversion ratio were recorded with Nano-selenium than all other treatments at 35 day of age. In conclusion, under semi-arid conditions, usage the Nano-selenium are not harmful to the embryo (injected with 15 ppm) and can be used to improve the post-hatch performance of broiler under semi arid condition.

In ovo injection of nano‐selenium spheres mitigates the hatchability, histopathology image and immune response of hatched chicks

“…It plays a significant role in stimulating the hydrogen and lipid peroxides reduction hence promotes immunity against foreign invasion (Upton, Edens, & Ferket, 2008). One of the methods that can increase Se bioavailability and efficacy is using nano form through in ovo injection (Hassan, 2018;Joshua, Valli, & Balakrishnan, 2016;Lee et al, 2014;Sogunle et al, 2018). The results showed the health condition of hatched chicks, which improved by injecting LAB-nano-Se in ovo.…”

“…Furthermore, this technique ameliorated the immune response and increased the resistance against diseases, which resulted in low posthatch mortality and morbidity (Ferket, 2011). The micronutrients, vitamins, trace elements, amino acids, vaccines and functional feed additives can be injected to help the high-metabolism and fast-growing of broiler embryos (Bello, Hester, Gerard, Zhai, & Peebles, 2014;Foye, Ferket, & Uni, 2007;Goel, Bhanja, Mehra, Majumdar, & Pande, 2013;Goel, Bhanja, Mehra, Mandal, & Pande, 2016;Hassan, 2018;Lee et al, 2010;Macalintal, 2012;Pender et al, 2017;Sogunle, Elangovan, David, Ghosh, & Awachat, 2018;Zhai, Bennett, Gerard, Pulikanti, & Peebles, 2011).…”

“…Chickens are suffering from various stressors that occur on the farm, including high density, heat stress and diseases (Saleh et al, 2020). Microelements are essential in maintaining the health and growth of chicks due to its vital physiological and biological roles (Dawood, Koshio, Zaineldin, Van Doan, Ahmed, et al, 2019;Dawood, Koshio, Zaineldin, Van Doan, Moustafa, et al, 2019;Dawood, Zommara, Eweedah, & Helal, 2019;Hassan, 2018;Mahmoud, Ijiri, Ebeid, & Ohtsuka, 2016). Selenium (Se) is a vital microelement that can improve the immune and antioxidative responses by the reduction of the hydrogen and lipid peroxides, which produces during the stress and infections (Suchý, Straková, & Herzig, 2014).…”

“…It is well reported that using the nanoforms of microelements is more effective when applied in the diet formulation at adequate levels (Wang, 2009). As a result, the chicks can grow adequately without immune and health deteriorations (Boostani, Sadeghi, Mousavi, Chamani, & Kashan, 2015a, 2015bHassan, 2018;Saleh, 2014).…”

Effect of zinc nanoparticles on embryo and chicken growth, and the content of zinc in tissues and faeces

“…In Phase 1, administration of NanoZnO at the beginning of embryogenesis had no effect on BW, but increased the heart weight and decreased the liver weight of embryos at 19 days. The lack of influence on BW at hatch was also demonstrated by Josuha et al (2016), who injected NanoZnO at 18 days of incubation, and by Hassan (2018) when the injection took place at the beginning of incubation. The percentage of live embryos was lower in the NanoZnO treated groups than in the Control.…”
