Escore de condição corporal e desempenho reprodutivo de vacas leiteiras mestiças lactantes

The objective was to evaluate the effect of lactation order, racial composition and milk production in the body condition score (BCS) at prepartum and its variation at postpartum. Furthermore, evaluate the effect of BCS at prepartum and its variation at postpartum on reproductive performance in dairy cows. Data was collected, relating to 470 parturitions for two years at 3 properties in Gurinhatã-MG. Milk production was measured monthly and the evaluation of the BCS was made by a single individual in the prepartum and postpartum (from 1.0 to 5.0). Was used the conventional artificial insemination, timed artificial insemination and controlled ride. The pregnancy diagnosis was through rectal palpation from 40 days after the service. The variables were analyzed using the SAS GLIMMIX procedure. The racial composition affected the BCS at prepartum (P=0.0003). Milk production tended to affect the BCS at prepartum (P=0.0957) and its variation in postpartum (P=0.1179). The overall conception rate was 57.3% and was affected (P<0.0001) by type of service. There was no effect of the BCS in prepartum (P=0.1544) and the variation of BCS (P=0.3127) on conception rate. Had no effect of BCS interaction at prepartum (P=0.9516) and the variation of BCS (P=0.9506) with the type of service on conception rate. The BCS at prepartum affect the service period (P<0.0001). Cows with BCS less than 3.25 became pregnant earlier. The variation of the BCS affected the service period (P<0.0001). Cows with loss of ECC became pregnant earlier than cows without loss. The average loss of ECC at postpartum was -0.692 points, not enough to damage the reproductive performance of dairy cows.

Relação entre a cárie precoce da infância com o índice de Apgar e outros fatores de risco

The aim of this cross-sectional study was to investigate the association of early childhood caries (ECC) with the Apgar score (AS) and other variables related to the child (conditions at birth and medical history) and related to the child and parents and / or guardians and family (demographic, socioeconomic and behavioral). One hundred and twenty healthy children aged between 3-5 years-old treated by Pediatric Dentistry Area of Dentistry College of the Federal University of Uberlandia during 2015 were selected. To obtain qualitative and quantitative variables a questionnaire was applied as an interview to the parents and/or guardians. The 5-minute AS (interest exposure) was obtained through the record in the Child Health Handbook. To assess the prevalence of caries (clinical dependent variable), a single calibrated researcher conducted the clinical examination, according to the criteria of the World Health Organization. Caries experience was measured using the indexes dmft and dmfs. The children were classified into three groups, according to age and dmfs index: no caries (NC), with ECC and with severe early childhood caries (S-ECC). Data were tabulated and submitted to statistical analysis using the SPSS software (IBM, Inc, Chicago, Illinois, USA) 17th version. Three logistics models were carried out having the following classifications: NC and ECC, NC and S-ECC, ECC and S-ECC (p<0.05). The overall ECC prevalence, considering children with ECC and S-ECC, was 55,8% (n= 67). The AS was not a statistically significant variable. The child’s age, weaning age and recent hospitalization were variables associated with the ECC prevalence. The age of brush start and the educational level of the mother were variables associated with the S-ECC prevalence. Considering the ECC and the S-ECC groups, the child's age and the beginning of the use of fluoride toothpaste, recent hospitalization, the educational level of the mother and the father's income were associated with the S-ECC prevalence. Considering the methodology employed and the analysis of results, it was concluded that there was no association between the ECC with the AS in healthy children. However, an association was found of ECC and S-ECC with some variables related to birth and to medical history of the child (recent hospitalization), demographic (child’s age), socioeconomic (educational level of the mother and father's income) and behavioral (age of brush start, weaning age and use of fluoride toothpaste) related to children and to the parents and/or guardians.
