Talazadeh F, Houshmandi KK., Effect of malt extract on lactic acid bacteria and lactobacillus in intestine and crops of Ross broilers, Onl J Vet Res., 24 (3):146-149, 2020. We determined lactic acid bacteria and lactobacillus (CFU/g102) in intestine and crop of day old Ross broilers given 0.2, 0.3 and 0.5% barley malt extract in drinking water daily for 42 days. Controls were not supplemented. At day 42, a gram of crop and ileo-cecum content were cultured on MRS for lactic acid bacteria counts. Compared with controls, the suppplement had no effect of lactic acid bacteria counts. However, malt extract increased dose related lactobacillus counts in ileo cecal content by ~49-59% and in crop contents ~64% (P < 0.05).
Keywords: malt extract, lactobacil counts, crop, intestine, broiler chickens.
