Abstract

The villous height to crypt depth (V:C) ratio is one of the most significant parameters which is associated with the nutrients’ absorption and greater body weight. The objective of this study was to assess the relationship between V:C ratio, gut bacteria counts and production parameters in broiler chickens. A total of 100 individual broilers were randomly selected from a farm with 40,000 Ross 308 chickens and slaughtered for sampling at three different ages including 14, 28 and 37 day old. Villous height and crypt depth were measured for each section of the small intestine to calculate V:C ratio. Intestinal score and gut microbiology including total coliforms, lactic acid bacteria and Salmonella prevalence were assessed. At day 37, besides those parameters, the carcass, breast, legs and wings were taken for weight measurements. Leg and breast color was also measured. Data were statistically analyzed by STATA software to explore the relationship between V:C and those parameters. The results showed the positive correlation between V:C of duodenum and the number of lactic acid bacteria at 28 days of age (P < 0.05). Moreover, the leg yield was negatively related to the V:C ratio of jejunum (P < 0.05). No significant correlations were found between V:C ratio and other parameters. The results indicated the potential of controlling V:C ratio to improve gut health and meat quality of broiler chickens and thus, further studies should be conducted to fully evaluate these correlations.
