The effect of feed particle size in laying hens on the digestive tract morphology - a preliminary report
Original language description
The influence of feed particle size on laying hens' parameters were evaluated. Laying hens of LOHMANN BROWN CLASSIC were divided into 2 different experimental groups - coarse group and fine group. The differences between the diets was in particle size. The structure of diets was evaluated by dry sieving using a separator Retch AS 200 Control. Geometric Mean Diameter (1,339.49 vs. 564.24, respectively) and Geometric Standard Deviation (1,369.11 vs. 393,56, respectively) of diets were calculated. The different feed mixtures (coarse and fine) feeding had no influence (P > 0.05) on live body weight, blood biochemical parameters, feed consumption and most of digestive tract section of lying hens. The statistically significant difference (P < 0.05) was found on the weight of proventriculus. The bigger proventriculus was found in fine group compared to coarse group.
