The objective of this thesis was to evaluate the effect of citrus extracts on intestinal integrity, 448 were used in laying hens of 50 weeks old of the Hy line brown. The chickens were distributed through completely randomized designed with two treatments and eight repetitions: Base diet (DB) and base diet (DBEC) being the experimental unit of 28 laying hens’ four cages of seven birds. The diets formulated to meet the nutricional requirements of hens of the Hyline Brown line in phase two comercial stance, having the same nutricional and energy value. The results were analyzed through the analysis of varience (ANOVA) and avarage compared with the turkey”s test. The results on intestinal integrity, between the measure of villus height crypt dept and villus crypt ratio in the jejunal portion in the 25 and 50% portion in laying hens 56 weeks of age; it had a significant different (P> 0.05), in favor of the diet that used citrus extracts (DBEC),having values of 890.70 and 277.15um, and a V/C ratio of 3.21for the portion of the jejumum at 25%and 173.45um and V/C ratio of 4.46, for 50%jejunal portion,therefore it is concluded that the use of citrus extracts in diets of laying hens improves intestinal integrity.
