Question:
“Abstract” the influence of grinding size of the main cereal of the diet on the production and egg traits was studied in brown hens from 33 to 65 weeks of age. The experiment was completely randomized with 6 treatments arranged as 3x2 factorial with 3 main bowls of cereal (barley, corn, and wheat)and 2 grinding sizes of the cereal (6- and 10-mm screen). Each treatment was replicated 11 times (10 hens/replicate). Diet was is nutritive and contained 2740 Kcal/Kg AMEn and 16.8% CP. Egg production ADFI, egg weight, and feed conversation ratio (FCR) were determined period (4 weeks) and for the entire experiment. Egg quality traits (percentage of undergrads, Haugh units, thickness, strength, the color of the shell, and proportion of albumen, yolk, and cereal of the diet were observed for any of the traits studied. Feed intake, egg production, and BW gain were not affected by the diet of grinding size. Eggs were heavier (P<0.01) in hens fed barely than in hens of fed corn or wheat, probably because of the higher fat content of the bare diets. Also, FCR tended to improve in hens fed barely compared with hens fed corn or wheat (P = 0.07). Diet did not affect any of the egg traits studies. Consequently, the inclusion of one or other cereal in the primary on their relative cost diet will depend on the range studied, the screen size (6 vs 10 mm) limited effects on hen production.
