Effectiveness of Phytogenic Feed Additive as Alternative to Bacitracin Methylene Disalicylate on Hematological Parameters, Intestinal Histomorphology and Microbial Population and Production Performance of Japanese Quails

摘要: This study was conducted to evaluate the effects of phytogenic additive and antibiotic growth promoter in laying Japanese quails. One hundred sixty five quails were divided into three groups 5 replicates 11 (8 females 3 males) each replicate. Treatment 1 fed control diet, treatment 2 diet supplemented with 0.05% bacitracin methylene disalicylate as 0.1% feed (PFA) for two periods weeks from 37 42 age. Results showed that egg production, eggshell strength, weight, villus height crypt depth ratio significantly (p≤0.05) increased consumption, conversion ratio, albumen, Haugh unit, cholesterol, low-density lipoprotein, alanine transaminase, gamma glutamyltransferase, alkaline phosphatase, high-density triglyceride, number goblet cell, intestinal bacterial population Coliforms, Salmonella E. coli decreased PFA group. It is concluded addition containing phytomolecules organic acids main ingredients could improve production parameters general health an alternative promoters.
