This study aimed to investigate the impact of zinc oxide nanoparticles (ZnONPs) as
opposed zinc oxide to the conventional form at different levels on the growth performance,
intestinal microbiota, immune status, bone quality, kidney and liver functions, and thyroid
hormones in broilers. Total 360-day-old male chicks Arbor Acres from 1-35 days of age,
were divided into six treatment groups (6 groups x 6 replicates x 10 chicks each). Six diets
were formulated to meet Arbor Acres chicks’ nutritional requirements except for Zn,
which was given at three levels: 100% (of the strain guide required level), 50%, and 25%
of conventional or nano zinc oxide (ZnONPs).The findings indicated that chicks exhibited
superior productive performance when fed diets containing ZnONPs. There were no
statistically significant differences (P>0.05) observed within the various levels of ZnONPs.
Furthermore, the ideal characteristics of the tibia bone (Weight, length, width, and
breaking strength) recorded for chicks fed ZnONPs. Moreover, the chicks that were fed
ZnONPS had the highest levels of tibia bone ash, calcium, phosphorus, and zinc content.
Bone mineral density and concentration were evaluated in chicks fed ZnONPs using X-ray
and dual-energy X-ray absorptiometry (DXA) techniques, which demonstrated the
significant positive effect of nanoparticles in increasing bone mineral density and
concentration compared to the conventional form. No significant differences (P>0.05)
were observed in the percentages of carcass features among all treatments. Also, there
were no significant differences (P>0.05) observed among the various treatment groups in
terms of thyroid hormones level, kidney function as indicated by creatinine level, and liver
function as indicated by ALT and AST levels. Adding ZnONPs to the diets significantly
boosted (P≤0.05) the chicks' immune response to avian influenza (H5) and Newcastle
disease (ND) compared to the control group. In addition to chicks fed diets containing
ZnONPs, the growth of beneficial bacteria was enhanced while restricting the growth of
harmful types in the duodenum and cecum compared to the chicks fed the conventional
zinc.
From the current results, the inclusion of ZnONPs provided the best productive
performance and bone quality while having no adverse impacts on thyroid hormones, liver,
or kidney functions. As a result, the appropriate level of nano zinc was 25% of the
recommended level (27.5 mg/kg). هدفت هذه الدراسة إلى دراسة تأثير أكسيد الزنك في شكله النانوي مقارنةً بالشكل التقليدي، وذلك بمستويات مختلفة من كلا الشكلين، على أداء النمو، المحتوي الميكروبي للأمعاء، الحالة المناعية، جودة العظام، وظائف الكلى والكبد، وهرمونات الغدة الدرقية في كتاكيت التسمين. تم تقسيم 360 كتكوتًا من سلالة "أربور أيكرز" من عمر يوم الي 35 يومًا إلى ست مجموعات تجريبية (6 مجموعات × 6 مكررات × 10 كتاكيت لكل مجموعة). باستثناء الزنك، الذي تم إعطاؤه بثلاث مستويات هي 100% (من المستوى المطلوب وفقًا لدليل السلالة)، و50%، و25% من أكسيد الزنك التقليدي أو النانوي (ZnONPs)، تم صياغة ستة أنواع من الأعلاف لتلبية المتطلبات الغذائية لكتاكيت "أربر أيكرز". أوضحت النتائج أن الطيور أظهرت أداءً إنتاجيًا متفوقًا عند تغذيتها بأعلاف تحتوي على ZnONPs.
