“…There were no differences in weight due to the use of different prebiotics. Nevertheless, no differences were seen in carcass yield due to the use of probiotics and prebiotics, and these results were similar to findings reported by Maiorka et al (2001), Moreira et al (2001) andVargas Jr. et al (2002).…”

“…Many studies have confirmed the viability of using such products to improve animal production indexes (Besnard et al, 2000;Maiorka et al, 2001 andPelicano et al, 2004). Nevertheless, the utilization of these additives must be better evaluated not only as growth promoters, but also based on their effect on the production of prime cuts and high-quality meat.…”

This study evaluated the use of different probiotics, prebiotics and symbiotics on the quality of carcasses and meat of broiler chickens. One hundred and eight day-old Cobb male broilers were used (n=108) in a completely randomized design according to a 3x3 factorial, with 3 probiotics in the diet (no probiotics, probiotics 1, probiotics 2) and 3 prebiotics in the diet (no prebiotics, prebiotics 1, prebiotics 2). There were nine treatments with 4 replicates and 3 birds per replicate. The results showed that the carcass and cut yields, color (L* -lightness, a* -redness, and b* -yellowness), pH, cooking losses, shearing force and sensory analysis were not affected by the use of different growth promoters at 42 days of age. It was concluded that growth promoters supplemented to the diet did not affect the studied quantitative and qualitative parameters of the carcass and breast meat of broiler chickens.

Evaluation of the use of probiotic (Bacillus subtilis C-3102) as additive to improve performance in broiler chicken diets

et al. 2012

-The objective of this experiment was to evaluate the use of probiotic based upon Bacillus subtilis C-3102 (BS) in broiler diets containing or not conventional additive growth-promoter (AGP). A total of 1,824 one-day-old chicks of the Cobb-500 strain were used and distributed into 48 plots (1.50 × 2.00 m). A completely randomized design with four treatments and 12 repetitions was adopted. The treatments evaluated were: 1-Negative Control -AGP-free diet (NC); 2 -Positive Control, with AGP halquinol 30 mg/kg diet (PC); 3 -NC + BS (3x10 5 cfu/g diet); and 4 -PC + BS (3x10 5 cfu/g diet). The diets were on corn, soybean meal and meat and bone meal basis, formulated according to the nutrient allowances of the Strain Cobb Guide, following a feed program with three diets (starter, grower and finisher). At 21 and 42 days of age, feed intake, weight gain and feed conversion were evaluated, and carcass yield characteristics were determined at 42 days of age. Throughout the trial period (starter and total phases), better feed conversion was found for broilers fed diet with both additives (AGP and BS) combined. At the end of the experiment (1 to 42 days), the highest weight gain also occurred in broilers fed diets with a combination of the two additives. In present study, the use of BS or AGP alone in diets did not affect the performance of broilers. The carcass yield was not influenced by the use of the additives and beneficial effects of supplementation of BS and AGP combined in the diet on broiler performance were observed.

“…Maiorka et al (2001) supplemented a basal diet to broilers with additives and observed that the chicks fed a non-supplemented diet had better feed conversion results.…”

Performance of broilers experimentally inoculated with Salmonella Typhimurium and fed diets with addition of lactulosis

et al. 2012

-The objective of this experiment was to evaluate the influence of lactulose on performance as well as its ability to prevent colonization by Salmonella Typhimurium in broilers orally inoculated with this pathogen. The design adopted was completely randomized, with 630 one-day-old male chicks distributed into six treatments, with seven replications and 15 birds per experimental unit. The treatments comprised the following procedures: T1 (control group) -no S.Typhimurium inoculation or supply of lactulosis; T2 -only inoculation of S. Typhimurium; T3 -only lactulosis supply; T4 -supply of lactulosis and S. Typhimurium inoculation on the first day of life; T5 -supply of lactulosis 48 hours before S.Typhimurium inoculation; and T6 -supply of lactulosis 48 hours after inoculation of S. Typhimurium. Performance variables were evaluated on the seventh, 14th, 21st and 28th days of age; fragments of the duodenum and jejunum were collected and sent to histomorphometric assessment at 14 days of age, and S. Typhimurium excretion was verified in cloacal swabs on the 10th, 24th and 35th days of age. Performance data were analyzed by ANOVA and Tukey's test (5%) and fecal excretion data were assessed by non-parametric chi-square test. Better weight gain and feed conversion were observed in groups fed lactulosis with or without challenge of S. Typhimurium up to 21 days of age. Reduced duodenum villous height was verified on the 14th day in groups challenged with the pathogen. Reduction of S. Typhimurium fecal excretion was verified in broilers fed lactulosis from the first day of life on and 48 hours before receiving S. Typhimurium directly into the crop. Lactulosis increases broiler performance up to one week after its inoculation, influences duodenum villous height and reduces the fecal excretion of Salmonella Typhimurium.
