Fenugreek (Trigonella foenum-graecum) seed meal is rich in bioactive phytochemicals that can enhance growth and health. The present study aimed to evaluate the effects of graded dietary levels of fenugreek seed meal on growth performance, carcass traits, haematology parameters, lipid profile, liver function, and thyroid hormones in broiler chickens.
Materials and methods: A total of 256 day-old broiler chickens were divided into four dietary treatments, replicated four times with 16 chickens per replicate. The groups included the control diet (T1), diet containing 100 g/kg of fenugreek seed meal (T2), 200 g/kg of fenugreek seed meal (T3), and 300 g/kg of fenugreek seed meal (T4). The study lasted 49 days, and at the end of the study, growth performance, carcass traits, and haematological parameters were measured. Serum lipid profile, including total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and liver enzymes, including alkaline phosphatase (ALP), alanine transaminase (ALT), and aspartate aminotransferase (AST), were analysed. Thyroid hormones, including thyroxine (T4) and triiodothyronine (T3), and thyroid-stimulating hormone (TSH), were measured by enzyme-linked immunosorbent assay.
