ABSTRACT
The present study was conducted to evaluate the effects of feeding broilers with garlic fermented by Leuconostoc citreum SK2556. A total of 250 male broiler chicks was randomly housed into 25 floor pens. Five dietary treatments with five replicates of 10 chicks each (n=50 chicks/treatment). A corn and soybean meal based diet was used as the control diet (NC). The experimental diets were formulated by mixing the basal diet either with antibiotics (10 ppm; PC) or fermented garlic (FG) at the concentrations of 0.1% (FG1), 0.3% (FG3) or 0.5% (FG5) in diets. Daily weight gain, feed intake, and feedgain ratio were not affected by any of the dietary treatments. Average daily gain on day 21 linearly increased (p= 0.024) with increasing FG levels. The relative weight of the bursa of Fabricius showed a progressive decline with increasing the FG levels. Jejunal villus height was not influenced by dietary treatments. Villus width linearly decreased as FG levels increased (p= 0.17). Jejunal crypt depth was significantly lower (p < 0.05) in the FG1 and FG3 groups compared with the NC group. Villus height crypt depth ratio linearly increased (p= 0.018) with increasing FG levels. The population of cecal microflora was not altered by dietary treatments. Broiler chickens fed the FG5 diet exhibited (p < 0.05) higher blood levels of total protein and cholesterol compared with those fed the NC diet. Collectively, the results show that dietary FG marginally affected growth performance, especially during the first days rearing, improved intestinal morphology, and altered blood characteristics of broiler chickens.
