INFLUENCE OF Azadirachta indica L AS PHYTOGENIC FEED SUPPLEMENT ON THE GROWTH PERFORMANCE AND IMMUNO

This research looks at Azadirachta indica (neem leaf) as a phytobiotic feed addition to synthetic antibiotics in broiler chicken production. A total of 300 Arbor-Acre day-old broiler chicks were randomly assigned to six different food treatments, each with fifty birds. Each treatment was repeated five times, with each replicate including ten birds. There were six isocaloric and isonitrogenous diets created. Diet 1 (0 percent NLM; +ve control), diet 2 (0 percent NLM; -ve control), diet 3 (0.50 percent NLM), diet 4 (1.00 percent NLM), diet 5 (1.50 percent NLM), and diet 6 (1.50 percent NLM) were the basal diets supplemented with neem leaf meal (NLM) (2.00 percent NLM). When compared to those on diet 1 (+ve control), NLM supplementation boosted body weight gain by 2.29-5.41 percent at 1-3 weeks of age and 2.51-4.98 percent at 1-6 weeks of age (P = 0.05). Broiler chicken slaughter, dressed weights, white blood cell (WBC) counts, heterophil, monocytes, and platelets all improved (P = 0.05), while aspartate aminotransferase (AST), alanine aminotransferase (ALT), alanine phosphatase (ALP), glucose, low density lipoprotein (LDL), cholesterol, and triglycerides all decreased significantly (P = 0.05). In conclusion, Azadirachta indica leaf meal revealed to be a viable alternative to synthetic antibiotics in broiler hens, improving weight gain, immune system function, and overall health.
