The present study revealed that there was a significant (P<0.05) effect of betaine on body weight, feed intake, and feed conversion ratio (FCR) of the broiler. Productive performance and blood cholesterol level of the broiler. A total of 150-day-old broiler chicks (Cobb 500) were placed into five dietary treatment groups: T0 (control diet), T1 (0.03% betaine in water), T2 (0.06% betaine in water), T3 (0.09% betaine in water), and T4 (0.12% betaine in water). Each group consisted of three replications containing 10 birds in each. Body weight gain (BWG), mortality rates, and meat yield characteristics were recorded. The collected data were analyzed by one-way ANOVA using SPSS version 25.00 software. Above, the total body weight was significantly highest in T2 (1758.3 ± 7.61 g), followed by T1 (1602.6 ± 10.16), T3 (1632.5±12.68 g), T4 (1606 ± 22.65 g), and T0 (1425.5 ± 10.14 g), respectively. The FCR was found to be lowest in T2 (1.36) and highest in T0 (1.49), whereas the FCR of T1, T3, and T4 were 1.43, 1.39, and 1.38, respectively. It was found that there was a significant difference (P<0.05) between the dietary groups for carcass weight, live weight, thigh weight, and breast weight. It was found that there was a significant difference among the treatment groups for cholesterol levels. During the experimental period, there was no mortality among the dietary groups. The T2 group generated a much larger net profit per broiler. Betaine supplementation in broilers is advantageous for growth performance, economic benefit, and lipid profile when used at 0.06% through drinking water, according to this study's findings. In the production of broilers, it may also be the best substitute as a growth promoter, stress reliever, and immune booster.
