| Abstract | An experiment was conducted with 32 week-old 470 ISA-Babcock B380 laying hens, housed in floor pens with wheat-straw litter, to study the replacement of the antibiotic growth promoter (bacitracin zinc 30 ppm) with sodium butyrate (300 g/ton) in the diet. Results in 24 weeks of experimentation were similar between treatments (P > 0.05), in: egg production (92.6 and 91.9%), egg weight (63.0 and 62.9 g), egg mass / bird / day (58.4 and 57.7 g), feed consumption / bird / day (123.6 and 124.3 g), feed conversion (2.11 and 2.15), egg albumen quality (Haugh Units 82.9 and 83), yolk color DSM fan (10.3 and 9.9), shell thickness (0.392 and 0.394 mm) and weight of the shell (6.26 and 8.03 g). According to information obtained in 24 weeks with 32 week old hens, the addition of sodium butyrate to feed as a substitute for the growth promoter (bacitracin zinc), was similar in the productive performance and egg quality.Keywords : Sodium butyrate; layer performance; egg shell quality. |
