“…It is reported that MOS can alter the gut microbial population in nonruminants in a desirable manner by selectively binding to the micro-organisms in the gut (Spring et al, 2000, Shane, 2001Newman et al, 1994). Therefore favorable microorganisms like lactobacilli will be able to further suppress the growth of harmful micro-organisms in the chicken gut (Vandevoorde et al, 1991;Hinton et al, 1992;Pascual et al, 1999) thus improving the feed digestibility and nutrient utilization (Schneitz et al, 1998) which in turn results a better performance of the animal. In the present study, MOS had significantly reduced the cfu of duodenal coliform bacteria (Table 4) thus avoiding their negative effect on the performance of birds.…”

Two bio-assays were conducted to evaluate turmeric root powder and mannan-oligosaccharides (MOS) as alternatives to feed antibiotics for broilers. In one trial, one hundred and eighty 19-days old broilers assigned to 18 groups of 10 were fed on one of six experimental diets with three replicates during four weeks. The diets included a basal feed without additives and with either virginiamycin, MOS, or turmeric at 1, 2 and 3 g/kg, respectively. In the second trial, one hundred and forty four 21-days old broilers arranged in 16 groups of nine were fed on the first four diets with four replicates for a similar period. Virginiamycin, MOS and turmeric (1 g/kg) in the first trial generally improved the weight gain of broilers by 3.4, 6.2 and 5.3%, respectively. In the second trial they increased the weight gain significantly (p<0.05) by 8.8, 8.0 and 15.1%, respectively. Additives improved the feed efficiency up to 15.1% and carcass recovery up to 3.1% (p<0.05). Virginiamycin, MOS and turmeric (1 g/kg) markedly reduced the abdominal fat content from 1.91% BW in the control to 1.44, 0.97 and 1.2% BW, respectively, in the first trial. The corresponding values obtained in the second trial were 1.01, 0.55 and 0.6%, respectively as compared to 1.22% in the control group. All additives showed a remarkable inhibition of duodenal coliform bacteria, yeast and mould in the caecum, and all viable microbes in the ileum. A significant (p<0.05) improvement in energy and protein utilization could be recorded with supplemented diets except for high turmeric diets. Dietary 2 and 3 g/kg addition of turmeric reduced energy and protein utilization as well as fat deposition. Present results reveal that turmeric and MOS are satisfactory alternatives to antibiotics in broiler feeds. Both MOS and turmeric possess an antimicrobial effect in vivo. Turmeric may also depress fat deposition in broilers.

“…Lactobacilli play a distinctive role in the microbial balance of the chicken gut. In experiments simulating the chicken crop, the antagonism of lactobacilli against Enterobaeteriaceae and S. typhimurium was demonstrated and was attributed to lactic acid production -( Van de Voorde et al, 1991) The present study aimed to investigate the effect of dietary lactic acid bacteria with or without enzymes supplementation on live performance, carcass characteristics and meat quality.…”

Two hundreds and twenty-five male Hubbard broiler chicks at one day old were divided into five groups (45 chicks each.). Each group was assigned for one of five experimental diets. The first group was fed starter diets (0-2 week), grower diets (2-4 week) and finisher diets (4-7 week) as a control diets. However, the groups 1,2,3 and 4 were fed on the control diet with the addition of Micro-Bac (LA), Avi-Bac (LAE), LA + LAE and LAE + LA respectively. At the 7 th week of age, nine birds of each group (Three per each replicate) were slaughtered and blood samples were taken at slaughtering to determine serum cholesterol. Representative samples of fresh white breast meat were analyzed for chemical composition. The pH and plasticity of meat (breast and thigh) were determined after slaughtering at 0.5, 2, 4, 6, 24, and 48 h during storage at 4°C and cooking loss of meat was determined after 24 h. Contents of digestive tract were collected to determine the total bacterial count, total lactic acid bacterial count, L.acidophilus count, Coli form bacteria, Salmonella viable count and Staphilococcal viable count. Supplementing the basal diet with either LA or LAE gave no significant differences in body weight gain, feed intake and feed conversion at 2, 4 and 7 weeks of age. However, there were improvement in body weight gain and feed conversion in chicks fed LA+LAE at 2, 4 and 7 weeks of age by 9.0, 4.7, 2.8% and 1.5, 8.2 and 10.6, respectively.On the other hand, LA supplementation and/or LAE to broiler has been shown to decrease the mortality rate compared to the control group. No significant differences were observed in the percentage of dressing, and abdominal fat between chicks fed basal diet (control group) and these of other treatments.The meat of supplemented treatments were lower tender as indicated by lower plasticity values when compared with control diet. The lowest value of cooking loss was that of the control supplemented treatments tended to decrease the total cholesterol, triglycerides, HDL, and LDL in meat and serum cholesterol. All supplemented treatments inhibited bacterial growth of pathogenic bacteria.
