10 days old “Cobb 500” broiler chicks were used to investigate the influence of probiotics and growth promoter supplementation on growth performance and different hemato-biochemical parameters of broilers. They were randomly divided into three equal groups (n=10). Group A was considered as control, fed only with commercial ration and group B and group C were supplemented with probiotics and growth promoter respectively for the period of 21 days. Body weights were measured at 7 days interval and selective organ weights, total erythrocyte count(TEC), hemoglobin (Hb) concentration, packed cell volume (PCV), AST and ALT values were measured at the end of experiment. Results revealed that body weight was increased significantly (p 0.05) differences were found among groups of A, B, and C in the weight of breast meat, liver, Leg meat and spleen. All weights were increased significantly (p>0.05) both in probiotics and antibiotic growth promoter treated groups as compared to that of contr...

Many alternative substances have been investigated for their potential to replace antibiotics as growth promoters. Probiotics and phytobiotics are some of the products that can be used as growth promoters in broiler. The present study was designed to investigate either single or combined effect of a probiotic and phytobiotic on serum biochemistry and growth performances in broilers. A total of 50 Cobb-500 day old chicks were divided into five groups (10 birds each). The birds of Group A were offered a basal diet (corn-soya based), Group B basal diet + 0.10% Renamycin 100 ® , Group C basal diet + 0.15% probiotic (Bio-Top ®), Group D basal diet + 0.10% phytobiotic (Galibiotic) and Group E basal diet + 0.15% Bio-Top ® + 0.10% Galibiotic. Body weight, feed intake, weight gain, feed conversion ratio (FCR) and serum biochemistry (Triglyceride, cholesterol, LDL, HDL, ALT, AST, creatinine) were recorded. Serum biochemical values differed significantly (P<0.05) among the groups. The average final live weight gain was 665grams, 686grams, 1095grams, 780grams and 1065grams in groups A, B, C, D and E, respectively. The feed conversion ratio was 2.1, 1.96, 1.72, 1.83, and 1.75 in A, B, C, D and E group, respectively. The present study revealed that supplementation of probiotic and phytobiotic in feed significantly reduced triglyceride, cholesterol and HDL values compared to value of control group (P<0.05). Probiotic or its' combination with phytobiotic has the potential to be exemplary alternatives to antibiotic as growth promoters.
The experiment was conducted to evaluate the effects of probiotics on broiler chicken to find out growth performances and hematobiochemical values. A total number of one hundred and eighty day-old-broiler chicks (Cobb 500) were allowed to take rest for 15 days for the adaptation and supplied with normal diet and water. After day 15 among the 180 birds, fifteen broiler chicks (15) were selected and randomly divided into three equal groups (n=5) and marked them as group T 0 (control group), T 1 (BIO-TOP ® treated group) and T 2 (curd treated group). All the birds of these groups were reared under standard managemental procedure for the next 23 days. On the day 38 of age body weight, weight of legs, weight of liver and weight of skin including feather of birds of treated groups (T 1 and T 2 ) increased significantly (p<0.01) as compare to control group (T 0 ). The dressed weight and breast weight are also increased in treated groups compared to control group. TEC increased significantly (p˂0.05) and ESR decreased significantly (p˂0.05) in treated groups. Hb also increased in the treated groups compared to control group. Serum triglyceride and HDL decreased significantly (p<0.01) in all the treated groups. Total cholesterol level also decreased but the alkaline phosphate increased significantly (p˂0.05) in the treated groups compared to control group. It can be concluded that the supplementation of probiotics is highly beneficial for body weight gain and health condition of broiler.

EFFECT OF DIETARY SUPPLEMENTATION OF MULTI-STRAIN PROBIOTIC ON BROILER GROWTH PERFORMANCE
The effects of a multi-strain probiotic (protexin) on broiler growth performance, carcass parameters and economic efficiency were studied. For this purpose, 270 day-old broiler chicks were randomly divided into three experimental groups A, B and C, with 90 chicks in each group having three replicates. Group A was fed commercial broiler diet without supplementation of protexin (control) and groups B and C were fed diets containing protexin 100 and 110g/t in starter and 50 and 55 g/t in finisher diets, respectively. Feed and water were offered ad libitum. The results showed that weight gain and feed conversion ratio were significantly (p<0.05) improved in chicks fed on protexin-supplemented diets compared to control diets. Weight gain of the chicks fed on diet C was significantly (p<0.05) better than chicks on diet B. Feed conversion ratio was non-significantly different in both the protexin-supplemented groups. Differences in feed intake, meat composition, dressing percentage and empty organ weights among all the diets were nonsignificant. However, abdominal fat content was reduced significantly (P<0.05) in supplemented groups. The study suggests that protexin supplementation is beneficial for better weight gains, feed efficiency and economic efficiency in broiler chicks.

One hundred and sixty 1-d-old Ross 308 broiler chickens were randomly assigned to one of five dietary treatments for six week. The dietary treatments were 1-Control, 2-Basal diets supplemented with prebiotic (1kg of ActiveMOS/ton) 3-Basal diets supplemented with probiotic (150/100/50gr of Protexin/ton of the starter, grower and final diets respectively) 4-Basal diets supplemented with synbiotic (1kg of Amax4x/ton) 5-Basal diets supplemented with acidifier (2 liter Globacid/ton). The highest body weight observed in synbiotic group, which was significantly (P<0.05) higher than control group. Prebiotic and acidifier groups showed similar body weight as synbiotic group (P>0.05) but higher than control group (P<0.05). The body weight of broilers in probiotic group was similar to control, prebiotic and acidifier groups (P>0.05). Daily weight gain were significantly (P<0.05) increased in experimental groups compare the control group. Total feed intake did not show any significant (P>0.05) difference between experimental groups. Feed conversion ratio decreased significantly (P<0.05) in synbiotic and acidifier groups compare the control group. However, there were no significant (P>0.05) differences in feed conversion ratio of broiler chickens in prebiotic and probiotic groups compared with control group. The weight of proventriculus, Gizzard, liver, and Bursa did not differ (P>0.05) between groups. Additionally, the weight of Spleen increased significantly (P<0.05) in probiotic group compared with control group.

An experiment was conducted with 120 Cobb-500 Broiler day old chicks to evaluate the effect of feeding probiotic (<em>Saccharomyces cerevisiae</em>) with or without growth promoter (GP). Birds were reared in open sided shed type house. Body weight and feed intake were measured and examined on day 0, 7, 14, 21, 28 and 32. Chicks were randomly divided into four groups having three replications. The number of birds in each replication was 10. Four diets were considered: control; probiotic (PB) @ 1ml/liter; GP @ 100g/50kg and GP plus PB (@ 1ml/liter+ 100g/50kg). The records were kept on body weight, feed intake and mortality while weight gain, feed efficiency (FE) and survivability were calculated. Temperature and humidity were recorded four times daily. At the end of the experiment, one broiler was sacrificed from each replication to determine carcass characteristics. Broiler chicks that received PB and a combination of PB+GP treatments showed significant improvement in per...
Effects of test mixture and commercial probiotic on broilers growth performance
Veterinarski arhiv, 2019
The objective of this study was to investigate the effects of test mixture or probiotic addition to drinking water on the growth performance of broiler chickens. A total of 240 one-day-old Cobb 500 chickens were distributed into three groups with eight replicates in each (10 chickens in each replicate). The control group of chickens (C) were without treatment. The chickens in experimental group E1 were treated with the commercial probiotic Probios ® and the chickens in experimental group E2 were treated with the test mixture (Lactobacillus acidophilus culture, inactivated baker's yeast, C vitamin, lactose and glucose) prepared using the authors' own recipe. Treatments of chickens were conducted during the first three days of life and for three days using the chickens' vaccination drinking water. The experiment lasted for 42 days. Feed and water were offered ad libitum during the experiment. Body weight, daily feed intake, body weight gain, feed conversion ratio (FCR), carcass weight, carcass yield and European production index (EPI) were studied in this experiment. The addition of the experimental probiotic significantly increased (P<0.05) body weight gain at 21, 35 and 42 days of age, however, the probiotic Probios ® improved body weight gain over the same period without any significant difference compared to the control group. FCR was significantly improved at 21 and 35 days of age in both E1 and E2 groups, but at the end of fattening the FCR was not affected. Feed consumption was not influenced by the treatments. The results obtained indicate that carcass weight significantly increased (P<0.05) in the groups of chickens treated by the test mixture or probiotic. It was concluded that addition of test mixture or probiotic improved body weight gain, feed conversion ratio, carcass weight and EPI.

The aim of this study was to investigate the effect of two commercially-available probiotics, based on Enterococcus faecium and Bifidobacterium genera on performance and cholesterol and triglyceride amounts of broiler chicks' sera. One hundred and fifty-six (156), day-old, Ross chicks were randomly divided into groups A, B, and C (52 each). The birds in group A received control diet during the experiment but those in groups B and C were, respectively, given control diet supplemented with Enterococcus faecium and Bifidobacterium genera probiotics based on their instruction. Each treatment had 4 replicates of 13 broilers. Twenty chicks were bled from each group on days 21, and 42 of age. The sera were assayed for cholesterol and triglyceride levels using commercial biochemical kits. Treatment effects on broiler body weight, feed intake, and feed conversion ratio were determined on a weekly basis. The results showed that in group A, the cholesterol and triglyceride amounts increased with no significant changes until 42 days of age. In groups B and C, these amounts had a non significant decline. At first and second bleeding, the cholesterol and triglyceride amounts of B and C groups were significantly lower than group A, but there was no difference between groups B and C. The administration of these two probiotics affected positively on parameters of broiler performance compared to the control group but there was no significant difference between probiotic-treated groups. It is concluded that inclusion of probiotics based on Enterococcus faecium or Bifidobacterium genera displayed a growth-promoting effect that was comparable to control diet and also decreased the cholesterol and triglyceride components of broiler chicks' sera.
The dynamics of probiotics on growth performance and immune response in broilers
2004
The research work was conducted on "Hubbard Isa Starbro" broilers to evaluate the dynamics of probiotics relating to live weight gain, carcass yield, weight of cut up meat parts and immune response. Day old broiler chicks were divided into four groups as group A (Vaccinated probiotics fed group), B (Nonvaccinated probiotics fed group), C (Vaccinated conventional fed group) and D (Nonvaccinated conventional fed group). Groups C and D were taken as control birds fed with commercial ration and groups A and B as experimental birds were fed with commercial ration with the addition of 2gm probiotics (Protexin ® Boost)/10 litres drinking water upto 6 week of age. The result evidenced the following information: (a) The th live weight gains obtained were significantly (p<0.01) higher in experimental birds as compared to control ones at all levels during the period of 2 , 4 , 5 and 6 weeks of age, both in vaccinated and nonvaccinated nd th th th birds. (b) A significantly (p<0.01) higher carcass yield occurred in broiler chicks fed with the probiotics on the 2 , 4 and 6 week of age both in vaccinated and nonvaccinated birds. The weight of leg was found nd th th significantly (p<0.01) greater for experimental birds as compared to control ones on the 2 , 4 and 6 week nd th th of age. A significantly (p<0.01) higher breast weight in broiler chicks fed with the probiotics was observed on the 4 and 6 week of age. Analogously a significantly (p<0.05) higher breast portion weight was found in th th experimental birds as compared to control ones during 2 week of age. (c) The antibody production was nd found significantly (p<0.01) higher in experimental birds as compared to control ones. Significant differences were also observed in the weight of spleen and bursa due to probiotics supplementation. The results of the study thus revealed that probiotics supplementation promoted significant influence on live weight gain, high carcass yield, prominent cut up meat parts and immune response.
