| Current assay evaluates the internal quality of eggs of Hy-Line W-36 hens, according to storage time, temperature and packaging. Two equal experiments, starting one day apart, were conducted with 140 eggs each. The two experiments were divided into two phases, from 1 to 9 days and from 9 to 21 days, in a randomized block design. In the 1st phase, the treatments were arranged in a factorial 2 x 3+1, packaging (with or without), time (3, 6 and 9 days), with control on the 1st day. In the 2nd phase, treatments were arranged in a factorial design 2 x 2 + 1, packaging (with or without), cooling (with or without), and control on the 9th day. Egg weight, albumen, yolk and shell percentage, yolk index and Haugh unit were evaluated. The internal quality was reduced... |

| Effects on diets with reduction of crude protein and methionine + cystine (RCP) and protease supplementation (PRO) for laying hens at different ages and their influence on the internal quality of eggs at different conditions (STO) and storage times (TM) are evaluated. Four hundred and twenty eggs from commercial Hy-Line W36 laying hens collected at 32, 44 and 58 weeks of age were used. Experimental design was completely randomized in a factorial scheme 3 x 2 x 2 x 2: RCP (control, enhancement of one and two times the enzyme protease), PRO (with and without protease), STO (room temperature and refrigerated) and TM (14 and 28 days), with seven replications of one egg per experimental unit. The factorial scheme 3 x 2 x 2 was used at 58 weeks of age, because... |
