Corn particle size variation effects on broiler performance, organ weights, and nutrient digestibility during the early growout period (day 1 to 21)

Nutritional evaluation of soybean meals varying in particle size

“…When comparing the current results for SBM to those obtained in a study with corn, Downs et al (2023) observed no significant treatment effects for BW or feed conversion among broilers fed diets containing 832, 1,432, or 2,036 μm corn. It was observed, however, that FCR worsened with increasing particle size ( Downs et al 2023 ).…”

“…When comparing the current results for SBM to those obtained in a study with corn, Downs et al (2023) observed no significant treatment effects for BW or feed conversion among broilers fed diets containing 832, 1,432, or 2,036 μm corn. It was observed, however, that FCR worsened with increasing particle size ( Downs et al 2023 ). The latter results and the results of the current study suggest that particle size for corn may have larger effects on broiler growth performance than SBM particle size because there were no significant differences between the diets containing 809 and 1,174 μm SBM for growth performance in the current study.…”
