Abstract: the objective of this study was to estimate tissue composition of the carcass from physical composition of commercial cuts of f1 crossbred goats (boer with females of non-defined racial standard) finished on native pasture with four levels of supplementation with concentrate (0.0; 0.5; 1.0 and 1.5% of bw in dry matter). it was used 24 non-castrated animals at initial body weight of 15.52 kg and at 120 days of age. the carcass was sectioned in the half, and from the lefthalf carcass, the following cuts were detached: leg, loin, ribs, shoulder and neck, which were dissected in muscle, bone and fat. carcass weight and yield were predicted from the weight and yield of tissues in the commercial cuts by regression analysis. all the cuts can be used to predict muscle and fat weight in the carcass. for the muscle, the relationship was linear and positive in the cuts leg, ribs, shoulder and neck, and cubic in the loin; for all the cuts, fat kept a linear relationship with the carcass. muscle and fat yield of all the commercial cuts showed a positive linear relationship with carcass yield, except for rib fat, for which a cubic relationship was found. considering all the results obtained and using the relationship with the highest determination coefficient, the ribs were the cut that provided the best estimate of the carcass muscle and fat yields of f1 crossbred goats (boer with females of non-defined racial standard) finished on native pasture.

Abstract: the present study aimed to assess the effect of supplementation on the performance of f1 (boer × females of no defined breed) goats finished in native pasture. the experiment was conducted at the universidade federal de campina grande, patos campus, paraíba, brazil, with twenty-four 120-day-old non-castrated f1 (boer × ndb) male goats, with a 15.52 kg live weight (lw). animals were distributed in four levels of supplementation (0.0; 0.5; 1.0; 1.5% of body) and six replicates. in order to perform the evaluation of dry matter availability, the herbaceous vegetation was divided into grass and herbaceous dicotyledon and evaluated at the beginning (5/28/2007), in the middle (7/9/2007) and at the end (8/6/2007) of the experiment. in the beginning of the experiment, the availability of grass dry matter was 1,102.89 kg/ha, and at the end of the experiment, the availability of the referred matter was greater (1,494.81); on the other hand, the opposite occurred for the dicotyledons, with a dry matter content of 1,759.46 kg/ha in the beginning of the experiment, and only 236.76 kg/ha at the end of the experiment. supplementation made it possible to estimate the increase in dry matter intake of 257.15 g/day and of 20.79 g/kg0.75/day, as well as the daily weight gain of 103 g for each percentage point increase that resulted from supplementation. the availability and nutritional quality of forage had a strong influence on the effect of supplementation on dry matter intake, with a negative response for supplementation levels of up to 0.74% of the live weight consequently, the finishing of f1 crossbred goats in a grazing area in the caatinga can be improved with the supplementation of concentrate at levels 1.0 to 1.5% of the live weight.

Abstract: the present study aimed to assess the effect of levels of supplementation with concentrate on the tissue composition of commercial cuts of goats finished in native pasture. it was used 24 non-castrated cross-bred f1 (boer × sprd) goats at the age of 120 days, with initial average body weight (bw) of 15.52 kg distributed in four levels of supplementation with concentrated feed (0.0; 0.5; 1.0 and 1.5% of body weight in dry matter) and slaughtered at 25.12 kg; 26.62 kg; 28.56 kg and 29.19 kg, respectively, corresponding to 218 days of life. the carcass was sectioned in the half, and from the left half of the carcass, the following cuts were separated: leg, loin, ribs, shoulder and neck, which were dissected into muscle, bone and fat, with the results expressed in weight and yield of the tissues in relation to the weight of the cut. supplementation incresead the muscle weight, as well as the fat weight and yield and decreased the muscle:fat relationship; however there was no influence on the proportion of muscle in the five studied cuts. therefore, in order to obtain better finished commercial meat cuts, supplementation of 1.0 and 1.5% of body weight is recommended. nevertheless, supplementation is unnecessary for obtaining lighter meat cuts with a good proportion of muscle.

Abstract: the objective of this study was to evaluate the effect of supplementation on the carcass characteristics of crossbred boer goats finished on native pasture. twenty-four boer crossbreed goats were used, 120 days old and with an initial 15.52 kg bw. the supplemental feeding was randomly assigned to the animals according to a completely randomized design with 4 supplementation levels (0.0, 0.5, 1.0 and 1.5%) and six replications (goats). the animals had access to the pasture from 7:30 a.m. until 4 p.m. throughout the experimental period and were taken to stalls to receive supplemental feeding in individual cages equipped with hods and a water. full and empty digestive tract (dt) were weighed, as well as the bladder and gall bladder to obtain the empty body weight (ebw). the visceras yield tended to be different from that observed for absolute weight, except for hoof yield that presented a decreasing linear behavior. the hot and cold carcass weights and the yields and the empty body weight and the biological yield presented positively response to the supplementation levels. regarding the participation of wholesale cuts in the carcass, only the neck yield presented linear effect in response to the increase in supplementation levels. full digestive tract and digestive content weights did not respond to the supplementation levels. the digestive content weight was decisive for the effect of supplemental feeding in the full digestive tract weight. wholesale cuts weight responded positively to the supplementation levels.

Abstract: introduction: this study evaluated the interobserver reliability of plain radiograpy versus computed tomography (ct) for the universal and ao classification systems for distal radius fractures. patients and methods: five observers classified 21 sets of distal radius fractures using plain radiographs and ct independently. kappa statistics were used to establish a relative level of agreement between observers for both readings. results: interobserver agreement was rated as moderate for the universal classification and poor for the ao classification. reducing the ao system to 9 categories and to its three main types reliability was raised to a "moderate" level. no difference was found for interobserver reliability between the universal classification using plain radiographs and the universal classification using computed tomography. interobserver reliability of the ao classification system using plain radiographs was significantly higher than the interobserver reliability of the ao classification system using only computed tomography. conclusion: from these data, we conclude that classification of distal radius fractures using ct scanning without plain radiographs is not beneficial.

Abstract: Objective: Identifying in the literature the care technologies used by nurses for people with colorectal neoplasia on Nietzsche’s conceptual perspective. Method: It consists in an integrative review of the literature held in the database: Latin-American Literature and Caribbean in medical health sciences Literature Analysis and Retrieval System Online, Database in Nursing, US National Library of Medicine, Cumulative Index to Nursing & Allied Health Literature, Scopus Info Site and Web of Science in December 2015. Results: 28 articles were selected to compose the final sample of this review, which were analyzed and categorized in management technology (86.20%), assistance technology (20.68%) and educational technology (10.34%). Studies published in the last five years have predominated (62.06%), in international territory (82.75%) and with evidence level IV (44.82%). Conclusion: Today the growth on the production about this theme has been highlighted, but there is an important discrepancy between the researches with high and low level of scientific evidence, showing the need of more studies about technologies that strengthen the experience of nursing.
