Abstract
BackgroundThe study examined the effects of Myristica fragrans seed meal (MSM) and Syzygium aromaticum leaf meal (SLM) dietary supplementation on the growth performance, health status, and meat quality of broiler chicken.MethodsA total of two hundred and forty 1-day-old broiler chickens were assigned the four dietary treatments: Diet 1/control (no supplementation), Diet 2 (0.25% MSM), Diet 3 (0.25% SLM), and Diet 4 (0.25% MSCM, i.e., MSM + SLM 1:1). The birds were fed ad libitum throughout the feeding trial.ResultsThe dietary supplementation of 0.25% MSCM resulted in higher body weight gain and lowered feed conversion ratio (p < 0.05) at the finisher stage and overall period, while feed intake was not statistically affected (p > 0.05) across the treatments. The dietary inclusion of MSM, SLM, and MSCM did not significantly influence carcass traits, relative internal organ weights, and haematological indices of the broiler chicken (p > 0.05) except mean cell volume and mean cell haemoglobin content (p < 0.05). The result further revealed that broilers fed diets supplemented with MSM, SLM, and MSCM had higher (p < 0.05) serum catalase, glutathione peroxidase and lowered serum cholesterol compared with control. The meat cholesterol levels and lipid peroxidation of the birds were significantly (p < 0.05) reduced, while glutathione peroxidase was increased by dietary MSM, and MSCM supplementation.ConclusionThe MSCM supplementation at 0.25% enhanced the body weight gain, improved serum, and meat glutathione peroxidase and catalase but reduced the broiler’s meat cholesterol level and lipid oxidation.

Summary
The study examined the effects of Myristica fragrans seed meal (MSM) and Syzygium aromaticum leaf meal (SLM) dietary supplementation on the growth performance, health status, and meat quality of broiler chicken. The recognition and utilization of herbs, spices, and their extracts as natural feed additives in poultry diets have increased in recent years due to their inherent multi-bioactive properties and ability to enhance performance traits, reduce pathogenic bacteria, and. Myristcan fragrans and Syzygium aromaticum plants are among the herbs and spices with a lot of potentials that can be utilized as feed additives in poultry production. The potential phytochemicals in Myristica fragrans plant have been reported to exert antioxidant, antimicrobial, antipain, antiobesity, and hepatoprotective activities in biological systems (Morita et al 2003; Olaleye et al 2006; Agbogidi and Azagbaekwe 2013; Yakaiah et al 2019). The dietary administration of Myristica fragrans extracts was reported to inhibit lipid digestion, absorption and accumulation of adipose tissue in the rat (Yakaiah et al 2019), reduce cholesterol level in rabbits (Sharma et al 1995), and prevent liver damage in the rat (Morita et al 2003). Despite the efficacy of Myristica fragrans seed in muscle food preparation, little or no work has been done on its dietary application in poultry production
