COMPARATIVE EFFICACY OF SYNTHETIC PROBIOTICS AND YOGURT ON EGG PRODUCTION, BODY WEIGHT AND HEMATOLOGICAL PARAMETERS OF LAYER

Abstract

The study was carried out to compare the efficacy of yogurt from synthetic probiotic on egg production, body weight and hematological parameter in layer at the about age of 80-85 weeks Hi Sex Brown breed. The study was conducted under the department of Physiology and Pharmacology. At 80 weeks of age, forty Hi Sex Brown breed were randomly divided into 4 groups (T0, T1, T2 and T3) and each group remain 10 hens. Group T0 was kept for control, Group T1 was treated with Probiotics (ProtexinR ) with water at a dose of 1.5gm, Group T2 were treated with Yogurt (Sour curd), Group T3 was treated with combination of both probiotic(ProtexinR ) and Yogurt. Over the course of the trial, observations were recorded for egg production, body weight and, hematological parameter. Egg production were increased significantly (p<0.05) in all treated groups in respect to the control group and highest was recorded in combine Group D treated with Probiotic and Yogurt Body weight gain were not significantly increase with compare to the treated group. Hematological parameter no significant (p>0.05) differences were observed among ESR (Erythrocyte Sedimentation Rate) and TLC (Total Leucocyte Count) of the treatment groups in case of hematological values in respect to the control group after treatment. But hematological parameter were significantly different between the PCV (Packed Cell Volume) at the level of (p>0.05) and Hb (Hemoglobin) level were significantly different (p>0.01). The present study reveals that combine Probiotic and Yogurt treatment (Group T3) was the best effective on egg production and profitability without making any health hazard of aged breed among all the treated groups.
