A pesquisa foi conduzida no campus da UFRuralRJ com o objetivo de comparar
o teor de minerais presentes nas fezes de animais que receberam a mesma dieta. O
delineamento experimental foi o inteiramente casualizado, em esquema fatorial 3 x 2, três -
grupos genéticos (bovinos Nelore, F1 Nelore x Sindi e búfalos Mediterrâneo) e duas
condições sexuais (castrados e inteiros), totalizando 24 animais. As fezes foram coletadas
diretamente do reto de cada animal e analisadas. Não houve diferença entre grupo genético e condição sexual para o teor de nitrogênio, magnésio e total de minerais nas fezes, enquanto para o fósforo, os animais castrados do grupo de bovinos apresentaram maior teor que os inteiros, 8,55 vs 6,38g/kg para o Nelore e 8,58 vs 5,39g/kg para o F 1 Nelore x Sindi, não havendo diferença dentro dó grupo de búfalos. As fezes de animais castrados apresentaram maior teor de cálcio que as de animais inteiros (21,1 vs 14,4g/kg), sendo que as de bovinos Nelore e F 1 Nelore x Sindi apresentaram maior teor de potássio do que buba1inos, 14,1 e 15,1 vs 8,8g/kg, respectivamente. Concluiu-se que, de modo geral, as fezes de bovinos são mais ricas em minerais do que as de bubalinos, bem como as de animais castrados em relação aos inteiros.

The feceswere directly collected from the rectum and analyzed. There were no differences between genetic group and sexual condition for nitrogen and magnesium content and for the whole mineral content of the feces, while for phosphorus, castrated animaIs from cattle grouppresented higher content than the non-castrated ones, 8,55 vs. 6,38 g/kg for Nellore and 8,58 vs. 5,39 g/kg for F 1 Nellore x Síndi, but there were no differences ín the buffaloes group. Feces of castrated animaIs presented higher calcium content than feces of the non-castrated (21,1 vs. 14,4 g/kg), butNellore andF 1 Nellore x Síndi cattle presented higher feces potassium contentthan buffaloes, 14,1 and 15,1 vs. 8,8 g/kg, respectively.

Oil palm is considered the crop with the highest oil production per planted area unit. This condition has driven the Brazilian government to create the Sustainable Oil Palm Production Program. Since 2009, the agroenergy production chain has used oil palm as a viable and profitable crop to recover deforested areas in the Amazon. The aim of this study was to assess hydric conditions able to indicate the potential to expand oil palm crops in the state of Maranhão, even in the Legal Amazon. The climate database used (average and extreme temperature in degrees Celsius; rainfall values; relative humidity, and vapour-pressure deficit). Water deficit values were was obtained by comparing the potential evapotranspiration of oil palm (ETc) to actual rainfall (ER). Water balance was calculated based on available water capacity of 125 mm.month-1. Evapotranspiration was obtained using the methodology according to the climate database available to calculate the evapotranspiration rate in an area planted with oil palm in this study. The water deficit values show no restriction in the soil water replacement between January and June. However, from July to December, the water deficit varies between 200 and 300 mm. The levels showed that, in the areas evaluated, oil palm crops will require irrigation. In this period, yield was estimated at 17 tons ha-1 when the water deficit was considered at 210 mm and 14 tons ha-1 for a deficit of 380 mm. This result reinforces that oil palm production may drop by more than 50% due to water deficits and the crop will greatly impact the economy and the environment if the irrigation strategy is adopted in the areas of Maranhão.
