Low cost artificial rearing would benefict dairy or dual-purpose goat production. In Experiment I, 32 British Saanen male kids were purchased at 1 to 6 days of age, after receiving colostrum. After castration they were allocated to a 2 x 2 factorial design to compare age at wearning (4, 8 weeks) and cold milk substitute allowance (ad libitum, AL, restricted, R, 0.85 1/day). Milk powder (based on dried skim milk and 20 percent fat) was reconstituted to produce 18 percent solids milk. Water and pelleted concentrate (barley, 77.9 percent, soya-bean meal, 9.6 percent, fish meal, 8.0 percent, molasses, 3 percent, minerals and vitamins, 1.5 percent) were offered and ad libitum before and after weaning, and until animals were slaughtered at 36 kg live weight. Animals were individually penned indoors and bedded on straw. All animals completed the experiment. Overall growth rate (g/day) and slaughter age (days) respectively were 4AL, 212, 160; 4R, 177, 181, 8AL, 233, 145; 8R, 197, 162. Total intakes of milk powder (kg) and concentrates (kg) respectively were, 4AL, 7.3, 105; 4R, 4.1, 122; 8AL, 19.0, 79; 8R, 8.3, 108. Experiment II involving 42 kids given milk substitute ad libitum and weaned at 4 weeks, showed that type of milk substitute (20 percent fat powder, 12 percent fat powder) had little effect on milk intake, but intakes decreased with increasing milk dilution (percent solids, 17.0, 13.5, 10.0). Experiment III with 18 kids showed little difference in concentrate intake before and after weaning due to physical form, ie. whole barley plus supplement, milled barley plus supplement, milled and pelleted barley plus supplement, but dry matter digestibilities were affected, 83.1, 78.0, 77.7 percent. High mortalities (33 percent) post weaning occurred in Experiment II due to starvation. This is thought to due to individual penning not allowing kids to see each other readily and thus learn to consume dry food MenosLow cost artificial rearing would benefict dairy or dual-purpose goat production.

Abstract: This paper applied pedological mapping in an experimental center of APTA-Frutas in Jundia´ý, S?ao Paulo, Brazil, using morphometric parameters and GIS tools. The aim of this work was to obtain a preliminary legend of a soil map and to compare the preliminary map with maps made by the traditional soil survey methods. The area has 59 hectares and is located at a mountainous relief in the Atlantic Plateau. The original soil map of this area was made at 1:10 000. A digital elevation model (DEM) was generated with 4m spatial resolution based on a topographical map at 1:10 000 scale, where the level curves are equidistant at 5 m. Based on the DEM we generated altitude, curvature and slope maps. In order to map the hydromorphic soils it was generated a buffer around the hydrography.We also calculated frequency distribution graphics of altitude, curvature and slope maps. After the interpretation of the frequency distribution, we defined classes to predict the soils types. The curvature map was divided into two class intervals (< or = 0 and > 0), the altitude map was divided into four class intervals (690, 703, 704,714, 715, 730, and 731, 757 m), and the slope map was divided into four class intervals (0-9, 10-19, 20-44, and 45-72%). The maps were reclassified and converted to sh,ape files. The shape files were intersected with the others to generate the final preliminary soil map. The methodology was adequate for the preliminary mapping of some types of soils. |
