Hematological responses to hyperimmune plasma low dose administration in foals during weaning / Respostas hematológicas da administração de baixa dose de plasma hiperimune em potros no período de desmame

Weaning is a development stage that brings maternal independence, change of management and feeding, leading to immune deficit. The objective of this study was to evaluate the hematological and biochemical parameters of foals in weaning phase after intravenous administration of hyperimmune plasma (1 mL/Kg) in low dose. Ten foal weaned from the Mangalarga Machador breed were used, being divided in control (GC; n=5) and treated group (GT; n=5). The results obtained show that hematological and biochemical parameters of foals that received low doses of hyperimmune plasma were within the reference range for the equine species.(AU)

O objetivo deste estudo foi avaliar os parâmetros hematológicos e bioquímicos de potros em fase de desmame após administração intravenosa de plasma hiperimune (1 mL / Kg) em baixa dose. Foram utilizados dez potros des-mamados da raça Mangalarga Machador, sendo divididos em grupo controle (GC; n = 5) e grupo tratado (GT; n = 5). Os resul-tados obtidos mostram que os parâmetros hematológicos e bioquímicos de potros que receberam baixas doses de plasma hiperi-mune estavam dentro da faixa de referência para a espécie equina.(AU)

Occurrence and antimicrobial resistance profile of Salmonella spp. in calves from the Mesoregion Sertão of Alagoas, Brazil / Ocorrência de Salmonella spp. em bezerros e perfil de resistência antimicrobiana na Mesorregião do Sertão de Alagoas, Brasil

The objective of this study was to verify the occurrence of diarrhea and the isolation of strains of Salmonella spp. in diarrheal feces of calves from farms located in the backwoods from the state of Alagoas municipalities, and to characterize the in vitro resistance profile of Salmonella sp. isolated against conventional antimicrobials. The study was carried out with 431 calves from 10 to 90 days old, and 111 diarrheal fecal samples from these calves were analyzed. The samples were sown in enrichment broths and selective culture media and phenotypic and molecular characterization were made. 25.75% (111/431) of the animals had diarrhea. The presence of Salmonella sp. was evidenced in 13.33% (2/15) of the studied establishments. 2.71% (3/111) strains of Salmonella sp. have been isolated and have all been shown to be resistant to Cefotaxime and sensitive to Ciprofloxacin, Gentamicin, Amoxicillin, Ampicillin and Norfloxacin. The occurrence of Salmonella sp. and other infectious agents associated with diarrhea were confirmed in calves in the backwoods from the state of Alagoas. The antimicrobial potential of the tested drugs reinforces the importance of their responsible use in the fight against Salmonellosis in these animals, thus promoting the minimization of cases of bacterial resistance in Brazil and in the world.(AU)

Objetivou-se verificar a ocorrência da diarreia e o isolamento de estirpes de Salmonella sp. em fezes diarreicas de bezerros provenientes de propriedades de municípios do Sertão Alagoano e caracterizar o perfil de resistência in vitro das estir-pes de Salmonella spp. isoladas, frente a antimicrobianos convencionais. O estudo foi realizado com 431 bezerros com 10 a 90 dias de idade, sendo analisadas 111 amostras de fezes diarreicas, semeadas em caldos de enriquecimento e meios de cul-tura seletivos e feita caracterização fenotípica e molecular. 25,75% (111/431) dos animais apresentavam diarreia. A presença de Salmonella sp. foi evidenciada em 13,33% (2/15) dos estabelecimentos estudados. Foram isoladas 2,71% (3/111) estir-pes de Salmonella sp. que revelaram-se em sua totalidade resistentes à Cefotaxima e sensíveis a Ciprofloxacina, Gentamicina, Amoxicilina, Ampicilina e à Norfloxacina. Confirmou-se a ocorrência de Salmonella sp. e outros agentes infecciosos associados a diarreia em bezerros no Sertão Alagoano. O potencial antimicrobiano das drogas testadas reforça a importância da utilização responsável das mesmas no combate a Salmonelose nesses animais, promovendo assim a minimização de casos de resistência bacteriana no Brasil e no mundo.(AU)

Efeito do dia da transferência de embrião na taxa de prenhez em éguas / Effect of the day of embryo transfer on pregnancy rate of mares

Embryo transfer in mares is a very important biotechnology to improve genetic material. The aim of thepresent study was to evaluate the best day for embryo transfer, according to the synchronization between thedonor and the recipient mare, evaluating quality and stage of the collected embryo. It was obtained an embryorecovery rate of 56.06% of the embryo flushes, a rate that was similar for D7, D8 and D9. There was nostatistical difference relating to embryo stage and quality and collection day, and neither to the pregnancy rateafter the transfer, according to the embryo age.(AU)
