Eradication of Salmonella Typhimurium in broiler chicks by combined use of P22 bacteriophage and probiotic

It has been reported that the phage therapy is effective in controlling the number of colony-forming unit (CFU) of Salmonella spp. in chicken gut. This paper describes the protective effect of phage and Lactobacilli administration on Salmonella infection in 1-day-old chicks. We administered the bacteriophage P22 in a single dose and a probiotic mixture of four species of bacteriocin-producing Lactobacillus once a day for one week. Samples were analyzed every 48 hours, and intestinal eradication of S. Typhimurium was confirmed after treatments. We observed an increase in the size of duodenal villi and cecal crypts, as well as an increase in body weight in groups that received daily doses of Lactobacilli. This study confirms the efficiency of bacteriophage therapy in controlling salmonellosis in chicks and the beneficial effect of Lactobacilli mixtures in the weight gain of the birds.

Ácido fumárico e quelato de cálcio e fósforo na ração de leitões desmamados

Two experiments (E) were carried out with the objective of evaluating the effects of fumaric acid and carbo-amino-fosfo-quelato of calcium diets of weaned pigs on performance (E1) and intestinal morphology (E2). A total of 96 and 32 pigs with initial mean weights of 5,66 kg ± 0,44kg and 5,34 ± 0,45kg , in E1 and in E2, were used respectively. Randomized block designs were used in both experiments, with a 2 X 2 factorial arrangement in E1 and a 2 X 2 X 2 factorial arrangement in E2. No interaction between acidifier, source of calcium and phosphorus were found for the variables studied in the two experiments. No treatment effects were found on daily feed intake in evaluating periods. Feed conversion from 0 to 17 days was better (P<0.05) when inorganic sources of Ca and P were fed; however, no difference was observed in other periods. The averages of villus height (AV), crypt depth (PC), AV: PC relationship and mucous membrane of the duodenum and of the jejunum didn’t differ among treatments. Considering the total nursery period, no benefit was found in using an acidifier, however the carbo-amino-fosfo-quelato of calcium studied may replace the inorganic sources in the diets of piglets, with no damage to performance and to intestinal morphology.
