Resumo: 	The objective of the present study was to evaluate the effect of dietary crude protein (CP) levels and the use of a nutritive solution via drinking water on the performance of pre-starter broilers. A total of 1,224 male Avian Farm chicks, from one to 40 days of age were used. Birds were distributed in a completely randomized experimental design with a 3 × 2 × 2 factorial arrangement, consisting of three initial body weights (low: 41 g, standard: 45 g and high: 49 g; two crude protein levels at the pre-starter phase (22 and 25% CP),with or without the addition of a nutritive solution, whose nutritional level was similar to the 25% CP pre-starter diet, at a concentration of 5% of the drinking water. Each treatment included six replicates and 17 chicks per experimental unit. At the end of the pre-starter phase, all hens received a diet with 22% CP until day 21 and a diet with 20% CP from the 21st to the 40th day. The use of the pre-starter diet with higher nutritional levels and the nutritive solution enhanced broiler performance. The early nutrient supply via drinking water resulted in better broiler performance and uniformity. However, birds with low initial body weight continued to present lower body weight at market age.
