Abstract
The current study was conducted to evaluate the
potential impact of dietary selenium nanoparticles (SeNPs) alone, in combination
with chitosan or loaded to chitosan on pectoral muscle quality and tibia bone
morphology in broilers. Two-hundred-and-forty day-old chicks were raised in five
groups, each group having eight replicates (n=6/replicate). The control group
received a basal diet whereas the other four groups received basal diet
supplemented with selenium nanoparticles (SeNPs-0.5mg/kg), chitosan
(COS-200mg/kg), SeNPs+COS (0.5mg/kg+200mg/kg) or SeNPs loaded to COS
(SeNPs-L-COS-200mg/kg), respectively. On day 35, two birds/replicate were
euthanized to collect blood, tibia bone, and pectoral muscle. Muscle pH,
selenium and calcium concentrations were significantly higher (P<0.05) in
broiler fed SeNPs+COS and SeNPs-L-COS while drip loss percentage was
significantly lower (P<0.05) in broilers fed SeNPs-L-COS when compared with
birds in the control group. Dietary SeNPs-L-COS resulted in significantly higher
(P<0.05) water holding capacity, muscle, fiber diameter and cross-sectional area
when compared with the control group. Bone weight and weight/length index were
higher (P<0.05) in broilers fed SeNPs+COS and SeNPs-L-COS compared to birds in
the control group. Diaphysis-diameter was higher (P<0.05) in broilers fed SeNPs
and SeNPs-L-COS groups in comparison with birds in the control group. Phosphorus
concentration was higher (P<0.05) in tibia bone in broilers fed SeNPs+COS and
SeNPs-L-COS when compared to birds in the control group. Thus, we conclude that
supplementation of SeNPs-L-COS improves breast muscle histology, tibia bone
health, mineral retention in tissue, and resulting meat quality in broilers.
