“…Feed intake (FI) and weight gain (WG) of the birds fed probiotics were similar to those of the NC birds in all rearing stages, except for those fed PR-III in the period of 1-40 days, which WG was lower than the NC birds (p<0.05) ( Table 2). Previous studies also found similar weight gain (Vargas et al, 2001;Lima et al, 2003;Pelicano et al, 2004) and feed intake (Pelicano et al, 2004;Flemming & Freitas, 2005) in birds supplemented or not with probiotics. According to Pelicano et al (2004), the similar or lower performance of birds fed probiotics as compared to negative control groups, may be due to an unbalance of the bird's gastrointestinal microflora consequent to the high number of microorganisms as compared to the quantities normally found in the digestive tract.…”

“…The inclusion of probiotics in the diet has shown to produce contradictory results on broiler performance. Researchers have reported positive (Maiorka et al, 2001;Correa et al, 2003;Dematte Filho, 2004) none or negative effects (Vargas, 2001;Lima et al, 2003;Pelicano et al, 2004;Flemming & Freitas, 2005;Gunal et al, 2006) on broiler performance attributed to the action of probiotics. This variation in results was shown by Faria Filho et al (2006) in their literature review.…”

The objective of this study was to evaluate the effects of different additives on broiler performance and meat quality. A total of 1620 one-day-old male Cobb broilers were distributed by a completely randomized experimental design into 5 treatments: positive control - zinc bacitracin (PC); negative control - without additives (NC); probiotic 1 - 10.000 g/ton (PR-I); probiotic 2 - 500 g/ton (PR-II); and probiotic 3 - 50 g/ton (PR-III). The PC treatment promoted better weight gain (WG) than PR-II (1-28 days) and PR-III (1-14; 1-28 days), better feed conversion (1-40 days period), and the highest WG among all treatments (p<0.05). The performance of broilers fed probiotics was not different than those in the negative control group in any rearing phase, but there were performance differences among probiotic-treated birds. Hot and cold carcass yields and breast pH were not influenced by the different additives as compared to the negative control treatment. The only observed differences were in breast color (a*) and carcass yield between PR-III and the negative control group. Probiotics increased water holding capacity (except for PR-II) (p<0.05). The treatment with antibiotic promoted the highest WG. Meat quality suffered little influence from the different additives

“…Considering the total rearing period, from one to 42 days of age, none of the treatments statistically influenced the evaluated parameters, which was also observed by Lima et al (2003), who worked with Bacillus subtilis (1 × 10 10 CFU/g product), Pelicano et al (2004b), who used Bacillus subtilis, Bacillus licheniformis, Lactobacillus reuteri and Lactobacillus johnsonii, Appelt et al (2010), who tested different Bacillus subtilis feed inclusion levels, Boratto et al (2004), Junqueira et al (2006) and Silva et al, (2011). On the other hand, Santos et al (2004), including antibiotics and probiotics in broiler feeds, despite not detecting differences in body weight, weight gain or feed intake in broilers from one to 42 days of age, showed that the antibiotic product promoted better feed conversion ratio.…”

-The objective of the present study was to evaluate the influence of a probiotic product (composition:Lactobacillus acidophillus (3.5 × 10 11 CFU), Streptcoccus faecium (3.5 × 10 11 CFU) and Bifidobacterium bifidum (3.5 × 10 11 CFU)) on broiler performance. A total of 1200 one-day-old broilers were reared until 42 days of age, and distributed in a completely randomized experimental design with 3 treatments (antibiotic, probiotic and control) with 10 replicates of 40 birds each. Weight gain, feed intake, feed conversion ratio and mortality were evaluated. Concerning weight gain, in the periods of 0-7 and 0-14 days of age, the group fed the antibiotic product presented higher values as compared with the other treatments. However, in the periods of 0-21, 0-28 and 0-35 days of age, birds fed the antibiotic presented higher weight gain only in relation to the control group. Feed intake differences were detected only in the initial period of 0-7 days of age, with the group fed the antibiotic product presenting higher feed intake as compared with that fed the probiotic product, although these groups were not different from the control group. No statistical difference was detected in feed conversion ratio among treatments in any of the evaluated age intervals. Mortality was different only in the period of 0-14 days of age, which was higher in the control group as compared with that of the birds fed the probiotic product, but it was not different from the group receiving the antibiotic. Treatment with probiotic product containing Lactobacillus acidophillus, Streptococcus faecium and Bifidobacterium bifidum does not affect broiler performance.

“…The results of present study are in line with Habibi-Najafi et al 24 , who reported that dietary supplementation of prebiotic increased the WHC of meat. On the other hand, Pelicano et al 25 reported that dietary inclusion of prebiotic has no significant effect on WHC of meat during storage condition. It is remarkable to note that water loss reduces meat nutritional value because some nutrients may be lost in exudate resulting in meat becoming less tender and bad in flavour.…”

Antibiotics have revolutionized the intensive poultry production system as a feed additive by promoting growth, production and meat quality through improving gut health and reduction of sub-clinical infections during last five decades. However, currently, the usage of antibiotics in poultry production is under severe scientific and public scrutiny, because antibiotic growth promoter (AGP) has been linked to the possible development of antibiotic-resistant pathogens, which may pose a threat to human health. After European Union ban on in feed antibiotics as growth promoter in poultry, since 2006, prebiotics offer a potential substitute to in feed antibiotics. In this effort, the objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physio-biochemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. 240 day-old broiler chicks (1 d) of uniform body weight were divided into 30 replicate groups having 8 birds in each. Six corn based dietary treatments were formulated viz. T1 (control diet), T2 (T1 + Bacitracin methylene di-salicylate @ 20 mg/kg diet), T3 (T1 + 0.1% MOS), T4 (T1 + 0.2% MOS), T5 (T1 + 0.1% FOS), and T6 (T1 + 0.2% FOS). Significant (P<0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T4 (0.2 % MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase (P<0.05) in 0.1 or 0.2 % MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher (P<0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower (P<0.05) in T4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased (P<0.05) in T3 or T4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physio-biochemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.
