Effect of in ovo supplementation of nano forms of zinc, copper, and selenium on post-hatch performance of broiler chicken

Abstract

Background and Aim:Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the study is to examine the effect of in ovo supplementation of nano forms of zinc, copper and selenium on the hatchability and post hatch performance of broiler chicken.Materials and Methods:Nano form of zinc at 20, 40, 60 and 80 µg/egg, nano form of copper at 4, 8, 12 and 16 µg/egg and nano form of selenium at 0.075, 0.15, 0.225 and 0.3 µg/egg were in ovo supplemented (18th day incubation, amniotic route) in fertile broiler eggs. Control group in ovo fed with normal saline alone was also maintained. Each treatment had thirty replicates. Parameters such as hatchability, hatch weight and post hatch performance were studied.Results:In ovo feeding of nano minerals were not harmful to the developing embryo and did not influence the hatchability. Significantly (p<0.05) best feed efficiency for nano forms of zinc (2.16), copper (2.46) and selenium (2.51) were observed, when 40, 4 and 0.225 µg/egg respectively were in ovo supplemented. Except in nano form of copper at 12 µg per egg which had significantly (p<0.05) highest breast muscle percentage there was no distinct trend to indicate that dressing percentage or breast muscle yield was influenced in other treatments.Conclusion:Nano forms of zinc, copper and selenium can be prepared at laboratory conditions. In ovo feeding of nano forms of zinc, copper and selenium at 18th day of incubation through amniotic route does not harm the developing embryo, does not affect hatchability.

Response of in ovo administration of zinc on egg hatchability and immune response of commercial broiler chicken

“…Yair et al (2013) In concurrence to our observation on post-hatch growth performance, most of the earlier works have reported in ovo administration of zinc did not improve growth performances of post-hatch chicks (Tako et al, 2005;Goel et al, 2012;Yair et al, 2013;Oliveira et al, 2015). On the contrary, Joshua et al (2016) reported in ovo administration of 40 μg nano zinc significantly increased body weight gain and FCR.…”

“…() observed administration of commercial diluents containing 0.5 mg of zinc along with manganese and copper reduced the hatchability (86%) compared to non‐administered control (94%). As per the recent work of Joshua, Valli, and Balakrishnan (), hatchability percentage on in ovo administration of graded levels of nano zinc (20–80 μg/egg) resulted in the hatchability of 96%–88%. The current study with either doses of nano zinc did not show any significance ( p > .05) variation on hatch weight (Table ).…”

In ovo delivery of various biological supplements, vaccines and drugs in poultry: current knowledge

“…In ovo feeding of nanoparticles of some minerals (zinc at 20, 40, 60 and 80 µg per egg, copperu at 4, 8, 12 and 16 µg per egg, and selenium at 0.075, 0.15, 0.225 and 0.3 µg per egg) did not affect the development of an embryo and hatchability percentage. There was a significant improvement in feed efficiency with zinc (2.16), copper (2.46) and selenium (2.51), when 40 µg, 4 µg, and 0.225 µg per egg respectively were used via in ovo administration . In ovo administered copper has been reported to be better utilized and less excreted than when fed post‐hatching to chicks .…”
