Abstract

The study evaluated the effectiveness of neem and bitter leaf extract as a natural feed additive for broiler chicks, focusing on feed intake, body weight gain, carcass parameters, and sensory evaluation of meat and its composition. A total of 122 unsexed Sasso chickens were randomly assigned to four treatments with three replications in a Completely Randomized Design (CRD). Feed intake, Average daily gain (ADG), and Feed Conversion Ratio (FCR) were analyzed for starter (1-21 days), finisher (22-42 days), and entire experiment periods (42 days), comparing daily offers and refusals. Four broilers were slaughtered and treated with bitter and neem leaf extract in water for different treatments (0 ml, 2 ml, 4 ml, and 6 ml per liter of water for T1, T2, T3 and T4 respectively), evaluating carcass evaluation at the end of the trial. The CP and ME content of neem leave powder (NLP) and bitter leave powder (BLP) were 22.90% and 2680.96 Kcal/Kg DM and 21.95% and 3020.85 Kcal/Kg DM respectively. The average daily feed intake (ADFI) during the entire period was 104.49,116.07,118.65,122.32 g/bird (SEM=2.03) for T1, T2, T3 and T4 respectively, and it was significantly higher (p<0.05) for T4 compared to other treatment groups. The body weight gain (BWG) during the entire experimental period was 45.95, 56.72, 57.92, and 61.95 g/bird/day (SEM=1.88) for T1, T2, T3 and T4 respectively, and significantly higher in T4. The Feed conversion ratio (FCR) during the entire period was 2.28, 2.04, 2.04, and 1.97 (SEM = 0.04) for T1, T2, T3 and T4, respectively and best for T4. Carcass's weight was 1331.96, 1622.01, 1674.27 and 1899.70gm (SEM=65.58) for T1, T2, T3 and T4, respectively, and it was higher in T4 than other treatments. The giblet organs and crop were significantly higher (P˂0.05) for T4. The serum cholesterol (SC) and white blood cell (WBC) of broilers in the experiment period were significantly (P˂0.05) lower for T4 as compared to other treatment. But Total protein (TP) was significantly (P˂0.05) higher in T4 among treatment groups which showed that the addition of extract in drink water of broiler had positive effect on the chicks’ blood. The study recommends a combination of neem and bitter leaf extract in 6ml/1lt of drink water as a beneficial natural feed additive for Sasso Chicken production.
