This study was developed with the aim of evaluating recombinant bovine somatotropin (rbST) on non-carcass components of goat kids of three genotypes. It was used 23 male goat kids of three genotypes, being 8 Alpine, 4 ½ Boer + ½ Alpine (½ BA) and 11 ¾ Boer + ¼Alpine (¾ BA), from which 12 received rbST e 11 control. The growth hormone used was the recombinant bovine somatotropin (rbST) and animals of treatment 1 received the hormone in the amount of 0.3 mg/kg live weight, from 45 days, adjusted in intervals of 14 days. Animals of treatment 2 (control) received saline solution in the same dosage and interval. The ½ BA goats presented a higher proportion of external non-carcass components (head, feet and skin) in relation to Alpine goats. Regarding the vital organs, such as lungs, kidneys and spleen, and the non-carcass components blood, internal fat and perinephric fat, Alpine goats presented higher values than ¾ BA goats. The administration of recombinant bovine somatotropin (rbST) did not produce effect on proportions and weight of non-carcass components. Proportions and weight of non-carcass components varied in function of genotypes, although animals were slaughtered at similar live weight.

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.

Better knowledge of the anthropogenic soils can help create future scenarios for the Amazon region through information that supports the sustainable planning. The aim of this study was to evaluate the spatial variability of soil physical anthropogenic and not anthropogenic in the region of Manipur, AM. In the study area we selected two, one with no anthropogenic soils (native forest) and another with anthropogenic soils (black earth archaeological). In each area, we established a grid measuring 70 x 70 m and the soils were sampled at the points of intersection of the grid with regular spacing of 10 by 10 feet, making a total of 64 sampling points in each landscape. Soil samples were collected at a depth from 0.0 to 0.10 I did the analyzes physical (texture, bulk density, macroporosity, microporososidade, porosity and aggregate stability). Then, the data were subjected to descriptive statistics and geostatistics. It was found that the anthropogenic and non-anthropogenic soils showed different behaviors in relation ace their spatial structures. The spatial variability that prevailed in anthropogenic and non-anthropogenic soil was moderate and weak indicating that these soils are strongly linked to changes in the soil by extrinsic factors. The soil was observed anthropogenic best results for total porosity, microporosity and bulk density, showing superior characteristics compared for agronomic soil not anthropogenic. And the range of values found in the above two areas were used in the mesh, showing greater spatial continuity in these environments.
