Abstract
Three biological trials were carried out at the Department of Poultry Science,
Veterinary College, Hebbal, Bangalore to study the effect in ovo and early chick feeding
of nano trace minerals viz. nano zinc, nano copper and nano chromium on broiler
performance. Early chick feeding was done with commercial diet, diet with nano zinc (40
mg/kg), nano copper (8 mg/kg) and nano chromium (0.5 mg/kg); in ovo feeding with 0.5
ml of normal saline, 40, 12 and 0.5 μg/egg of nano zinc, nano copper and nano
chromium, respectively into the amniotic fluid of 18 days old embryos and both in ovo
and early chick feeding with same level of nutrients described above. In each trial, after
hatching, 240 day old straight run broiler chicks were allocated into five treatment groups
each consisting of four replicates with twelve chicks each and all birds were fed as per
NRC (1994). The results revealed that in ovo feeding of nano trace minerals significantly
(P≤0.05) improved serum total protein, globulin, intestinal histomorphometry, lymphoid
organs weight and increased antibody titers against NDV and IBDV. Early chick feeding
or in ovo followed by early chick feeding of nano trace minerals significantly (P≤0.05)
improved over all body weight, feed efficiency, serum total protein, globulin, intestinal
histomorphometry, intestinal and lymphoid organs weight and increased antibody titers
against NDV and IBDV. In ovo and early chick feeding of nano zinc improved the
production performance and nano chromium improved the serum biochemistry and
immune response than other trace minerals
