The effect of mixture of Thyme and Garlic powder on laying hen performance and some blood parameters

This study was conducted to evaluate the effect of Thyme and Garlic powder on the quantity and quality of production, and some blood parameters on 128 hens of Hyline breed, Strains of W36 at 46 weeks of age. The experimental design was Completely Randomized Design with four treatments and four replications in 12 weeks and each experimental unit contains 8 laying hens in two cages. Treatments include (1) Blank diet without thyme and garlic, (2) Diet contain of thyme 0.5% with garlic 1%, (3) Diet contain of thyme 1% with garlic 1%, (4) Diet contain of thyme 1.5% with garlic 1%, in diets based on corn and soybean meal. Studying the results of qualitative and performance traits data showed there were not significant differences between treatments (P≥0.05). Numerically the highest daily egg product mean (53.56 g) and the amount of daily feed intake (92.63 g) and egg weight mean (62.67 g) is related to the treatment No.3, while the lowest feed conversion ratio (1.72) and the highest production percentage (85.86) is related to the treatment No.1. The blood characteristics with 1 percentage of mixed thyme and garlic powder was high significant Compared to other treatments and Blank(P>0.01).In general it can be concluded that qualitative and performance traits of egg were not affected by different levels of thyme and garlic powder but unlike Uric acid blood parameters(Total protein and Albumin) showed significant improvements.
