Abstract

This study investigates the effects of different diet forms and compositions on the blood parameters, intestinal histomorphometry and tibia traits of broiler chickens. A total of 180 one-day-old broiler chicks of the Indian River strain were used, with six treatments arranged in a 3x2 factorial design: three diet programs (P1, P2, P3) and two diet forms (S1: crumble/pellet, S2: crumble). Over five-weeks, blood parameters, intestinal samples and tibia traits were analyzed. Results indicated that diet form and composition significantly influenced blood parameters, intestinal morphology and tibia traits. Meanwhile, serum total protein, albumin, globulin, AST, creatinine, and uric acid showed no significant differences across diet programs. Total cholesterol was significantly higher in chicks fed p1 compared to P2 and P3. No significant differences were observed in villus height, width, or crypt depth between the diet programs or feed forms. However, p1 resulted in the lowest number of goblet cells compared to P2 and P3. All tibia bone measurements were not significantly affected by different treatments except tibia breaking strength.
In conclusion, blood parameters, intestinal histomorphology and tibia bone were not significantly affected by different feed programs, fed forms and their interaction except for total cholesterol, goblet cells number and tibia breaking strength
