RESUMEN

Os efeitos do uso de minerais complexados durante o pré-parto sobre a ocorrência de retenção de placenta foram avaliados em 135 vacas Holandesas de dois ou mais partos: grupo mineral iônico (69 animais) e grupo mineral complexado (66 animais). Em 55 desses animais foram também avaliadas as concentrações séricas da imunoglobulina G (IgG), Zn, Cu e a qualidade do colostro. O experimento foi realizado em delineamento inteiramente ao acaso, em arranjo em parcelas subdivididas. As concentrações séricas de IgG e dos microminerais foram avaliadas por análise de variância, sendo utilizados, respectivamente, os testes de Duncan e Fisher. A taxa de erro α admitida foi de 7%. Não foram observadas diferenças entre os grupos para ocorrência de retenção de placenta, qualidade do colostro, concentrações séricas de Zn e IgG (P>0,07), sendo observada diferença para a concentração de Cu (P<0,07). As concentrações de IgG foram diferentes nas semanas pré-parto avaliadas (P<0,07).


The effects of the use of complex minerals on the occurrence of retained placenta during pre-partum were valued on 135 Holstein cows from two or more deliveries. The animals were divided in two groups: ionic mineral (69 animals) and complexed mineral (66 animals). In 55 of these animals serum concentrations of imunoglobulin G (IgG), Zn and Cu and colostrum quality were also evaluated. The experiment was conducted in complete randomized split-plot design, serum IgG and trace minerals were evaluated by analysis of variance and used, respectively, Duncan's test and Fisher. The α error rate of 7% was accepted. There were no differences between groups for the occurrence of retained placenta, colostrum quality and serum concentrations of Zn and IgG (P>0.07), a difference was observed for Cu (P<0.07) concentrations. The IgG concentrations were different on the weeks pre partum evaluated (P <0.07).

RESUMEN

During paediatric dental treatment, non-collaboration and fearful reactions are frequently observed in the child client. The dentistry student must be prepared to cope with these reactions, particularly considering the importance of the relationship between dentists and patients in the promotion of oral health. The present study aimed to assess undergraduate dentistry students' perceptions of their ability to cope with non-collaboration situations in paediatric dentistry. A Likert-style questionnaire was used to analyse students' self-confidence levels, and proposed solutions to 10 problem situations the students would be likely to encounter were recorded. The questionnaire was administered to two undergraduate dentistry student groups from two different Brazilian Public Faculties, comprising 122 respondents. The self-confidence analysis indicated that it varied according to the extent of the child's reaction and the invasiveness of the procedure. Responses to the open-ended questions were categorised by solution proposed, and the analysis indicated that the most frequent responses were categorised as follows: tranquilising, explanation and restriction. Significant differences were found in tranquilising (with higher values for Faculty 2 than 1, and higher values for female students than male students at Faculty 2) and restriction (with higher values for female students compared with male student at both Faculties). The results and discussion focused on the aspects of training dentistry students' social and behavioural management skills.

RESUMEN

Quarenta e oito bezerras da raça Holandesa, de um a 60 dias de idade, foram utilizadas para avaliar os efeitos da adição ou não de Lactobacillus acidophillus, Bifidobacterium bifidum e Enterococus faecium ao leite sem resíduo de antimicrobiano (L) e ao leite de vacas em tratamento de mastite (LTM), sobre o consumo de alimentos, ganho de peso e incidência e duração de diarréia. O consumo de concentrado e água foi medido diariamente, e o ganho de peso semanalmente. Utilizou-se um delineamento inteiramente ao acaso, em esquema de parcelas subdivididas, com 12 repetições. Os tratamentos consistiram de um arranjo fatorial 2 x 2 (L ou LTM e ausência ou presença de probiótico). A adição de probiótico reduziu o número de dias com diarréia no grupo de animais que recebeu leite sem resíduo de antimicrobiano (P<0,05), mas não houve efeito sobre os animais que receberam leite de vacas em tratamento de mastite. Também não houve efeito do probiótico sobre os consumos de concentrado e de água, e sobre o ganho de peso e a incidência de diarréia.


Forty-eight Holstein calves from birth until 60-day-old were used to evaluate the effect of commercial probiotic Biobac® (Lactobacillus acidophillus, Bifidobacterium bifidum, and Enterococcus faecium) in addition to milk without antimicrobials residue or milk from mastitis treatead cows on theoccurrence and the length of diarrhea. Consumption of concentrate and water were daily measured and the weight was weekly measured. The experiment was carried out according to a random sample design with 12 repetitions for each treatment, arranged in a split plot. The plots were composed by four treatments combined in a factorial arrangement of 2x2. Subplots were composed by the evaluation times. The addition of probiotic was beneficial to reduce the diarrhea period in the calves fed milk without antimicrobial residue. The consumption of concentrate, water, and the weights of the calves were not different among the groups, irrespectively of probiotic supply.
