Desempenho reprodutivo de ovelhas mestiças da raça Santa Inês em Brachiaria humidícula e efeito do sexo no ganho de peso de cordeiros

The purpose was to evaluate the reproductive performance of woolless ewes due to the feeding management of offsprings and weaning age in addition to measuring the effect of gender on weight gain of lambs. Sixty-four Santa Inês crossbred ewes were distributed in a completely randomized design in a factorial 4 x 2 x 2 - four weaning ages (56, 70, 84 and 98 days), sex and feeding management of the offspring, each treatment with four replications. The ewes were managed with the offsprings at the foot in 14 paddocks of 1,5 or 2,0 hectares, formed with Brachiaria humidícola. The offsprings were born by single birth, of Santa Inês pure of origin (PO). After the weaning of all groups, sixty-four lambs (32 males and 32 females) were randomly assigned in individual stalls and confined for 30 days. The comparison of the parameters was carried out by the adjustment of the simple linear regression model. It was verified over time addiction of the offspring feed management of + 3,7% (P<0,05) for the calving intervals and of + 1,4% (P<0,05) for the service period. There was increasing linear effect (P<0,05) of weaning age on calving intervals and service period. It was verified over time, addiction of the offspring sex of + 2,0% (P<0,05) for the calving intervals and + 0,8% (P<0,05) for the ewes service period. It was observed over time addiction of sex of + 35,2% and + 36,9% (P<0,05), respectively, for the daily weight gain of lambs from birth to weaning and post-weaning in feedlot. The supplementation of the offspring in private feeder and the anticipation of the weaning age reduce the calving intervals and the service period of woolless ewes in Brachiaria humidicula pasture. The offspring sex is the source of variation in the analysis of reproductive efficiency of ewe's mat rices and in the weight gain of Santa Inês crossbred lambs from birth to weaning, and after weaning.

Estudo comparativo das representações sociais sobre diabetes mellitus e pé diabético

The study aimed to investigate social representations of the terms diabetes and diabetic foot in different populations. Participants were divided into groups: diabetics (GD); non- diabetics (GN); and non-diabetic healthcare professionals (GP). Personal data were collected, and subjects answered two questions that were expected to evoke five words that came to mind when they thought of diabetes and then diabetic foot. The evoked material was analyzed with the software Ensemble de Programmes Permettant l'Analyse dês Èvocations. A total of 161 subjects participated, including GD (n = 72) with a mean age of 56.12 ± 5.49 years; GN (n = 38) with a mean age of 54.29 ± 7.91 years; and GP (n = 51) with 34.95 ± 7.52 years. The term diabetes evoked 297 words in GD, 172 in GN, and 235 words in GP. The term diabetic foot evoked 180 words in GD, 90 in GN, and 236 in GP. The groups proved to be anxious for more information, thus confirming the need for awareness-raising and educational programs on diabetes, covering comprehensive issues concerning the disease.

Avaliação das características do líquido ruminal, hemogasometria, atividade pedométrica e diagnóstico de laminite subclínica em vacas leiteiras

The objectives of this study were to evaluate the characteristics of ruminal fluid, blood gas analysis, pedometer activity and suclinical laminitis occurrence, through the presence of secondary foot diseases in high production dairy cows, from a commercial herd. 200 Holstein cows originating from the same farm, located in Araçatuba/SP, Brazil, were divided into four groups, which are established from the daily milk production. Initially clinical examination of the cows was procedure, followed by sampling of rumen fluid, by esophageal tube. Fluid was evaluated for pH, color, odor, consistency, sedimentation, flotation and methylene blue reduction test. Venous blood samples were also collected for blood gas analysis, in addition to collecting data from pedometrics (number of steps) and daily milk production. Data were tabulated and submitted to correlation analysis. No animal had reported changes in rumen pH. Non-acid base imbalance were found, since the values of blood pH, PCO2, TCO2, HCO3- and BE were normal during hemogasimetric analysis. The pedometric was effective as a screening method to cows with foot diseases. It demonstrated reduction in the number of steps due to pain, correlated with lower milk production. However, the identification of foot lesions was only possible through specific digital clinical examination. The occurrence of 49.5 % of herd foot problems was due to the risk factors present in the farm. The abrasive concrete and inadequate facilities, also associated with the possible occurrence of sub-acute ruminal acidosis, were observed as risk factors. However, sub-acute ruminal acidosis was undiagnosed by the methods used. The correlation between the values of ruminal pH, and blood gas analysis pedometrics showed efficient for the early diagnosis of foot diseases and also in establishing the etiology of these diseases. Subclinical laminitis occurred primarily in cow's herd, considering the multifactorial etiology of this disease, occurrence and distribution of foot diseases diagnosed.

Segurança no trabalho de aplicação de agrotóxicos com o pulverizador de pistolas em citros

The purpose of this study envisaged the quantification of skin and respiratory exposures occasioned by work conditions during pesticide spraying of citrus fruits using hand gun sprayers; the evaluation of the efficiency of individual and group protection measures for the workers; the determination of workers' most exposed body regions; and the classification of work conditions, with and without the tested work-safety protection measures as recommended for the registered pesticides used to control the main pests and diseases that attack these types of trees and fruits. The AZR protection equipment proved to be the most efficient for the tractor driver, when spraying using pistol sprayers. The two sets of individual protection equipment that were checked also proved to be efficient. The most exposed regions of the tractor driver's body were the thighs, the front of the legs, the feet and hands. The most exposed regions of the individual sprayer working on foot were the hands and feet.

Influência de calços na orientação postural de indivíduos com escoliose idiopática

INTRODUCTION: The relationship between the orientation of the segments and the adjustments that can be triggered by shoe lift and insoles in scoliotic patients during maintenance of standing position is unclear. OBJECTIVE: To verify static changes and those associated with unilateral manipulations of shoe lift in the postural orientation in people with idiopathic scoliosis. MATERIALS AND METHODS: Experimental group composed of ten patients with idiopathic scoliosis with double curve (less 10°) and control group with ten participants without scoliosis (aging from 13 to 24 years). Participants were videotaped in upright stance, standing with no, low (1 cm), and high (3 cm) shoe lift, which were placed under right and left shoe. In each condition, the participant maintain upright stance for 15 seconds and reflective markers were affixed on specific anatomical places. Postural angles were obtained: high thoracic; medium thoracic; thoracolumbar; and lumbar, as well segmental angles: shoulder; scapula; pelvis; and knee. RESULTS: In the no shoe lift condition, differences were observed between groups for high and medium thoracic angles and for shoulder. With low and high shoe lift under the right foot, difference was observed between shoe lift heights for high thoracic, for pelvis and knee angles. With low and high shoe lift under the left foot, differences between groups were observed for thoracolumbar angle and between shoe lift heights for pelvis and knee angles. CONCLUSIONS: The shoe lift promotes reorientation in the lower regions of the spine and segments of pelvis and knee. It might be suggested that in the scoliosis with double curves, manipulation in the basis of support changes the alignment of the trunk that might promote structural reorganization and the search of new adjustments among segments in individuals with idiopathic scoliosis.
