Abstract

This study aimed to determine the effect of dietary creeping wood sorrel powder (Oxalis corniculata) and chromium supplemented to broilers (1-42 days) exposed to heat stress, on their performance and on the intestinal and caecal microbiota.

Area of study: Ilfov, Romania

Material and methods: The feeding trial was conducted on 60, day-old Cobb 500 broilers, divided equally in two groups, each group with six replicates (5 chicks/ replicate). The broilers were housed in an experimental hall at 32° C constant temperature and 23h light regimen. Unlike the dietary control diet (C), the experimental diet (E) was supplemented with 1% creeping wood sorrel powder and 20 mg chromium picolinate/ kg premix. One bird from each replication was slaughtered on days 28 and 42, and samples of caecal and intestinal content were collected for bacteriological analysis.

Main results: The dietary creeping wood sorrel powder and chromium supplements for heat-stressed broilers had no significant influence on their growth performance (1-42 d). Overall, E diet had a beneficial effect on the balance of the caecal microflora; however, in the intestine, E diet had a positive influence on the balance of the intestinal microflora, only for the samples collected at 28 days.

Research highlights: Dietary creeping wood sorrel powder and chromium supplements can be an efficient tool for maintaining a proper balance of intestinal microflora in heat-stressed broilers.
