Effect of Probiotic Consortium Administration in Improving Organ Function and Blood Biochemistry in Laying Chickens.

<b>Background and Objective:</b> Probiotics have been known as a potential alternative to replace antibiotic growth promotors and have many benefits for poultry health. This research investigated that how administering a combination of probiotics affects the health and physiological parameters of laying chickens. This includes understanding if and how probiotics can enhance organ function and influence blood biochemistry profiles in these birds, therefore they are used to increase the production of laying hens. <b>Materials and Methods:</b> A Completely Randomized Design (CRD) with 56 hens was used. The treatments with two consortium yogurt B1 (<i>Bifidobacterium</i> spp. and <i>L. acidophilus</i>) and B2 (<i>L. bulgaricus</i>, <i>S. thermophilus</i>, <i>L. acidophilus</i> and <i>B. bifidum</i>) consisted of a control group that was not given the same treatment as the control group (T0), Group-1 was treated with WSPE probiotic B1 2% (T1), Group-2 was treated with WSPE probiotic B2 2% (T2), Group-3 was treated with 2% probiotic B1 powder (T3), Group-4 was treated with 3% probiotic B1 powder (T4), Group-5 were treated with 2% B2 probiotic powder (T5) and Group-6 were treated with 3% B2 probiotic powder (T6), data were analyzed using Analysis of Variance (ANOVA) and followed by Duncan's multiple range test. <b>Results:</b> The giving consortium probiotics to laying hens has a significant effect on uric acid levels as well as decreased SGOT, SGPT and creatinine levels also increasing total protein, albumin and globulin levels. <b>Conclusion:</b> The use of probiotics 2% increased organ function, namely an increase in total protein, albumin and globulin levels.
