SILVA,Evandro Oliveira Onofre e; NESPOLO,Cássia Regina; Sehn,Carla Pohl; Pinheiro,Franciane Cabral; Stefani,Lenita MouraAbstract This study aimed to isolate lactic acid bacteria from sheep milk products and to characterize these microorganisms with a focus on their antimicrobial, proteolytic and lipolytic activities. Raw milk, pasteurized milk, pasteurized cream, and butter samples were collected, lactic acid bacteria were isolated and their proteolytic, lipolytic and antimicrobial activities were evaluated. Lactic acid bacteria...
Eucalyptus oil to mitigate heat stress in broilers
Petrolli,Tiago Goulart; Sutille,Maria Aparecida; Petrolli,Osmar José; Stefani,Lenita Moura; Simionatto,Anderson Tiecher; Tavernari,Fernando de CastroABSTRACT The objective of this study was to evaluate performance, hematological parameters, leukocyte counts, and respiratory microbiota of broilers under heat stress receiving eucalyptus oil supplementation. Cobb broilers (n = 1200) were randomly distributed on the first day of life in a factorial arrangement with additional treatment (2 × 2 + 1) with two periods of oil administration via drinking water (daily...
Sources and levels of selenium on breast meat quality of broilers
Boiago,Marcel Manente; Borba,Hirasilva; Leonel,Fábio Roberto; Giampietro-Ganeco,Aline; Ferrari,Fábio Borba; Stefani,Lenita Moura; Souza,Pedro Alves deQualitative characteristics of breast meat of broilers fed diets supplemented with different concentrations (0; 0.3 and 0.5mg kg-1) of selenium in the form of selenomethionine and sodium selenite were analyzed. A total of 1050 one-day-old male Cobb broiler chicks were arranged factorially at random to five treatments (two concentrations x two sources + control diet without addition of selenium) with 7 replicati...
Occurrence of antibodies to Toxoplasma gondii in rheas (Rhea americana) and ost...
Almeida,Amanda Brentano; Krindges,Michelle Mayara; Barros,Luiz Daniel de; Garcia,João Luis; Camillo,Giovana; Vogel,Fernanda Silveira FloresThis study aimed to verify the occurrence of antibodies againstToxoplasma gondii in rheas (Rhea americana) and ostriches (Struthio camelus) commercially breeding in Brazil. Blood samples from 20 rheas and 46 ostriches (young and adults) were serologically tested using a technique known as modified agglutination test (MAT) at an initial titration of 1:16 for ostriches and 1:25 for rheas. Antibodies against T. go...
