Abstract
ABSTRACT The aim of the study was to evaluate the intestinal morphometry of broilers at 42 days of age fed diets containing different levels of cottonseed oil, with and without addition of ferrous sulfate. A total of 560 male Ross chickens were used in a completely randomized design with a 4×2 factorial arrangement and five replications with 14 birds. The cottonseed oil levels tested were 0%, 2%, 4%, and 6%. At 42 days of age, one bird per replicate was collected for morphometric. Analyzed variables were villus height, crypt length and muscle wall thickness. The statistical analysis was performed using SAS, P=0.05. In the duodenum and ileum, there was no significant effect of interaction between the treatments. In the jejunum, only the length of the crypt, the treatment with cottonseed oil 2%, more ferrous sulfate resulted in lower values; however, the same oil content without ferrous sulfate led to a greater length, which was also observed in the treatment with 4% oil plus ferrous sulfate. Inclusion of cottonseed oil in broiler diets at 42 days of age does not impair their intestinal morphology. Supplementation with ferrous sulfate at these levels is unnecessary, since no improvement was observed in the intestinal morphometric.
