Effects of using thyme (Thymus vulgaris L.) and enzyme (Kemine) on performance and blood biochemical parameters of laying Japanese Quails
This experiment was conducted to investigate the effects of using different levels of thyme (Thymus vulgaris L.) medicinal plant and multi enzyme (Kemine) on performance and blood biochemical parameters of Japanese quails with 240 laying bird (6 up to 12 weeks) as a 2*2 factorial include two levels of thyme (0 and 0. 75 percent) and 2 levels of Kemine enzyme (0 and 0. 05 percent) in four treatments، 4 replicates and 15 laying quails in each replicate in a completely randomized design. Interaction between thyme and enzyme did not have any significant effects on egg production performance. Whereas egg weight in birds who consume thyme، was high (P<0. 05) and amounts of blood uric acid and eggshell thickness in birds who received enzyme and thyme in diets، increased (P<0. 05). The overall results indicated that using enzyme and thyme in Japanese quails diets can be have positive effects on egg weight and eggshell thickness.
