The experiment was conducted to determine the effect of crystalline progesterone on external egg quality XCparameters of eighteen Lohmann Brown hens. A single factor completely randomized design was used with each treatment replicated three times. Six different doses (0, 5, 10, 15, 20 and 25 mg/bird) of crystalline progesterone were administered intramuscularly via the keel muscle twice a week for a total period of six weeks. Data obtained were analyzed using GraphPad InStat® Eighteen Lohmann Brown layers were completely randomized into six treatment groups; each group comprised three replicates. The groups were gave different levels of crystalline progesterone at 0, 0.2, 0.4, 0.6, 0.8 and 1 mg/bird designated as treatment A, B, C, D, E and F, respectively. The objective is to evaluate internal egg quality parameters in Lohmann Brown layers across crystalline progesterone treatment groups. Table 1 shows statistically significant differences across Kruskal-Wallis Test used. All median values of table 1 and 2 on internal egg quality parameters were significantly increased by crystalline progesterone administration. In conclusion, crystalline progesterone affected ovulation rate, yolk and albumen volume in Lohmann Brown hens.
