Abstract

The current study aimed to determine how microplastics affect domestic chickens' growth rate, body temperature, digestive enzymes, hormone levels, hematology, and serum biochemistry. In the growth and body temperature record, bird body weight gain was minimum body temperature was maximum in group three (G3) as compared to others. The hematological parameters i.e. total white blood cell count (TWBC) count and mean corpuscular volume (MCV) were highest in G3 while, total red blood cell (TRBC) count and packed cell volume (PCV) were highest in G2. The creatinine kinase (CK-NAC), aspartate transaminase (ASAT), and urea showed maximum value in G3 while cholesterol, total protein, albumin, alanine aminotransferase (ALAT), and uric acid level was highest in G2. A significant increase in the level of amylase and total protease enzymes and all hormones i.e. luteinizing hormone (LH), thyroid stimulating hormone (TSH), follicle-stimulating hormone (FSH), triiodothyronine (T3), tetraiodothyronine (T4) was observed in G3 while the production of lipase enzyme remains unaffected. Overall, the experimental groups showed higher hormonal levels and enzymatic production while decrease in body weight gain which might suggest that food contaminants eventually lower chickens' net energy intake from food they consume and their energy reserves.
