Abstract
|
Coccidiosis is the most common parasitic disease of poultry which causes economic
damage not only by mortality, but also by impaired growth rate,malabsorption, body weight
loss, and the negative effects on the product's yield and quality. This study was conducted
to evaluate the effect of dietary supplementation with nanocurcumin on carcass characteristics
and physical and chemical properties of broiler chicken breast meat infected with
Eimeria acervulina, Eimeria maxima, and Eimeria tenella. Fifty one-day-old chicks were randomly
assigned to five treatment groups: (1) noninfected/nonmedicated, (2) infected/
nonmedicated, (3) infected/medicated (nanocurcumin 300 mg/kg), (4) infected/medicated
(nanocurcumin 400 mg/kg), and (5) infected/medicated (antibiotic). Carcass characteristics
of Group 3 improved in comparison with Groups 4 and 2, significantly (p < .05). Groups
3 and 4 decreased drip loss and cooking loss and increased protein content in comparison
with Group 2.Groups 3 and 4 showed significantly higher a* values in comparison to Group
2 at the first and the 30th day under freeze condition. TBARS value of Group 2 was higher
than Group 1,while Group 3 had significantly lower TBARS value than Group 2. SDS-PAGE
patterns and DSC profiles do not show any differences. Nanocurcumin (300 mg/kg) can be
used as a potential promising feed additive in poultry production.
