Animal Nutrition and Feed Technology, 13: 15-25. A study was conducted to evaluate the effects of different probiotics i.e Lactiflora (Lactobacillus acidophilus), Provisacc (Saccharomyces cerevisiae) on the growth performance, nutrient retention and immune responses of broiler chickens. Two hundred forty day-old broiler chicks (Vencobb) were randomly allotted to one of four treatments on the basis of body weight in a randomized complete block design. Each treatment had 60 chicks arranged in 3 replicates of 20 chicks each and reared for a period of 42 days. Dietary treatments were basal diet without any probiotics (control, T1 basal diet only), T2 (T1 + Lactiflora @ 0.05%), T3 (T1 + Provisacc @ 0.05%) and T4 (T1 + Lactoiflora @ 0.05% + Provisacc @ 0.05%). Chicks were vaccinated with New Castle Disease Virus (NDV) and Infectious Bursal Disease Virus (IBDV) and antibody titer was determined to assess the humoral immune response. Blood parameters analysis and a metabolism trial of three days duration was conducted during 6th week of growing periods. Dietary supplementation of probiotics significantly (P<0.05) enhanced growth performance by improving body weight gain, performance index and protein efficiency ratio. Growth performance and nutrient retention of Lactiflora supplemented group (T2) was significantly (P<0.05) better then control (T1) and Provisacc supplemented group (T3) but comparable to combination group (T4). Broiler chickens fed diet supplemented with probiotics showed a significant decrease (P<0.05) in cholesterol concentration compared to control group. Supplementation of Lactobacillus acidophilus and Saccharomyces cerevisiae either alone or in combination improved the antibody titres to NDV and IBDV as compared to untreated control group for all period of observation. It was concluded that combined supplementation of Lactobacillus acidophilus and Saccharomyces cerevisiae supplementation at the rate of 0.05% each is beneficial in improving growth performance, nutrient utilization and immune response of broiler chicken.
A total of 90 one-day-old male broiler chicks were fed on balanced ration for 15 days and then divided into 3 equal groups. Control group fed ration probiotic free, group 2 and 3 fed ration supplemented with probiotic at concentration levels 0.5 and 1.0g/kg ration respectively for 4 weeks.It was found that probiotic improve body weight gain and feed conversion ratio. Relative organs weights were not altered in groups of birds fed ration mixed with probiotic. Serum values of biochemical parameter (AST, ALT, ALP, total protein, A/G ratio, Ph) were not significantly changed in comparison to control group. Probiotic enhance the immune response of broiler chickens in a dose dependent relation as documented by increasing the serumNDHI antibody geometric mean titres to ND vaccine, phagocyte percentage and phagocytic index of peripheral blood monocyte of broiler chickens. We concluded that probiotic composed of 3 strains of bacteria (Pediococcus acidilactici, Pediococaoccus pentosaceus and Bacillus Amylolique-faciens) in addition to 2 strains of yeast(Pichia farinose and Dekera anomala) enhance body weight gain, feed conversion, growth performance and Newcastle disease antibody titres in broiler chickens. Moreover, probiotic was safe as proved by serum biochemical profile and relative organ weight of male broiler chickens.

A 42-d trial was conducted to compare the effects of probiotic, prebiotic and synbiotic supplements on growth performance, morphology of the jejunum, serum lipid profile and antibody response of broiler chickens. A total of 400 one-d-old male broiler chicks were randomly divided into four treatment groups of four replicates (25 birds per replicate) and fed corn-soybean meal diets. The dietary treatments consisted of a basal diet without any feed additive (control diet), a basal diet with added probiotics (diet Pro), a basal diet with added prebiotics (diet Pre), and a basal diet with added synbiotics (diet Syn). The birds fed diet Syn exhibited higher body weight gain (BWG) and better feed conversion ratio (FCR) than those fed the control diet during the entire experimental period (P<0.05). Feeding diets Pro, Pre and Syn significantly increased the villus height and villus height:crypt length ratio in the jejunum of broilers at 42 d of age (P<0.05). The birds fed any of the ex...
Effects of Commercial Probiotics on Productive and Physiological Performance of Broiler Chickens
2014
A study was undertaken to test the effect of three commercially available probiotics on productive and physiological performance, immune organ weights, duodenum histomorphology and intestinal microbial examinations of broiler chickens. A total number of 240 oneweek-old Cabb500 broilers were randomly divided into 4 groups with 3 replicates each group. 20 broiler chickens were placed in each replicate and the experiment lasted 6 weeks after start. Results revealed that supplementation of broiler diets with different types of probiotics have positive effects (numerically but insignificant) on both body weights and feed conversion ratio. Results of immunocompetent organ weights indicated significant differences in the weights of some lymphoid organs among the experimental groups. Results of total serum protein (STP), serum albumin (SA), serum globulin (SG) and serum immunoglobulin type M (SIgM) at 5 weeks of age revealed a significant (P≤ 0.05) increase in STP, SA, SG and SIgM of the tr...

Abstract: Among the alternative options of antibiotics as growth promoters (AGP) to reduce the antimicrobial resistance, probiotics are the attractive alternative which needs to compare at different doses with AGP on the intestinal health of Japanese quail. For this, a total 75 Japanese quails were equally assigned to five treatment groups having three replicates in each group (n=5). In addition to basal diet (control), four other groups were supplemented by AGP and probiotics at the dose of 0.015 gm/bird, 0.03 gm/bird, and 0.045 gm/bird. The results revealed, 0.03 gm/bird probiotics group had significantly (p<0.05) lower mean on gizzard and intestine relative weights (gm/kg) of 23.68 and 35.61; and the relative length (cm/kg) of duodenum, jejunum and ileum were 51.06, 137.30 and 101.95, respectively. Additionally, the villus height (VH) of jejunum and ileum had significantly (p<0.01) higher mean in 0.03 gm/bird probiotics group of 599.25 and 417.25 µm, respectively. Although, there was a quadratic relationship in VH of jejunum (p<0.001) and ileum (p<0.01), CD (p<0.01) and VH:CD (p<0.05) of duodenum with the probiotics dose, but only VH of jejunum and ileum (p<0.001) showed a linear interaction. The enumeration of intestinal bacteria was lower in AGP group but did not differ significantly (p>0.05) with 0.03 gm/bird probiotics group in which the E. coli, Salmonella, Staphylococcus and TBC mean was 5.160 log10, 4.440 log10, 2.923 log10 and 6.972 log10 CFU/gm, respectively. However, the highest pH was recorded in ileum in each group without any significant differences. In a short of, probiotics are effective substitute to AGP and having the potential effects on intestinal health especially for 0.03 gm/bird.
Effect of supplementation of multi-species probiotic on production performance of Japanese quail
An experiment was conducted to study the effect of multi-species probiotic on production performance of Japanese Quails. Three hundred Japanese quail day old chicks were randomly divided into a control and three treatment groups with three replicates of 25 each and reared in cages for six weeks. The basal diets were supplemented with multi-species probiotic to control, T1, T2, and T3 diets @ 0, 0.005, 0.01, and 0.02 % level respectively. The parameters such as biweekly body weight, FCR, and livability were recorded and analyzed. The groups supplemented with multi-species probiotic at 0.01, and 0.02 % level had resulted in significantly (P < 0.01) higher mean body weight (185.62±2.51g and195.05±2.12g), better FCR (2.84±0.03 and 2.69±0.04) respectively than other groups. It can be concluded that the supplementation of multi-species probiotic in diet at 0.01, and 0.02% levels were found to be beneficial for higher production performance of Japanese quail.
