In this study, the microclimate changes in silvopastoral systems are quantified at different time and spatial scales and compared with single-pasture systems. The study was conducted in a silvopastoral system in São Carlos, Brazil (22°01? South and 47°53? West). The silvopastoral system consisted of grass pastures [Urochloa (sin. Brachiaria) decumbens cv. Basilik] lined with strips of native trees spaced at 17 m. Continuous microclimate measurements (air temperature, relative humidity, wind speed, and incident photosynthetically active radiation) were carried out from September 2010 to September 2012 at two positions of the silvopastoral system (2.0 and 8.5 m from the rows of trees) and at a pasture under full sunlight, located in an adjacent area. The soil moisture was monitored weekly from 24 March 2010 to 1 April 2012 at distances of 0.0, 2.0, 4.75, and 8.5 m from the rows of trees. The rows of native trees reduced wind speeds (46% reduction) and changed the photosynthetically active radiation incidence pattern on the pasture (up to 40% reduction of incidence at the point nearest to the trees). The combined action of these factors promoted thermal and air humidity changes on the pasture at the different points measured. With respect to soil moisture, there was greater soil moisture removal at the sampling points near the rows of native trees under the silvopastora system, mainly due to enhanced exploration by tree roots at greater depths in dry spells or early dry periods, when compared with the midpoints between the rows.

Abstract: This study assessed the effectiveness of penetrating (PCB; 190 psi; N = 363) and non-penetrating captive bolt guns (NPCB; 210?220 psi; N = 92) to stun a total of 455 cattle (Zebu and Zebu Cross). Physical bolt parameters (momentum, kinetic energy and energy density) were evaluated. Clinical indicators of brain function were recorded after stunning (GR), after being hoisted (HO) and at the bleeding rail (BL). Physical bolt parameters (bolt velocity, momentum, kinetic energy, energy density and sectional density) were significantly higher (P < 0.001) for PCB. The need for two or more shots was more frequent for NPCB (210?220 psi; 29% vs. 12%, P < 0.001). Cattle were more likely to collapse at first shot with PCB (190 psi; 99%) compared to NPCB (91%; P < 0.002) which can be attributed to the higher values of bolt physical parameters. Incidence of eyeball rotation (5% vs. 1%) and righting behaviour (7% vs. 1%) were higher (P < 0.001) for NPCB (210?220 psi) at GR than PCB. The NPCB with 210?220 psi had a higher frequency of response to nostril stimulation (2% vs. 0%; P < 0.001) than PCB. Rhythmic respiration was more frequently found for NPCB with 210?220 psi at GR, HO and BL. Therefore, PCB with 190 psi was more effective in ensuring unconsciousness in cattle. Resumo: Este estudo avaliou a eficácia de pistolas de ar cativas penetrantes (PCB; 190 psi; N = 363) e não penetrantes (NPCB; 210?220 psi; N = 92) para atordoar um total de 455 bovinos (Zebu e Zebu Cross ). Parâmetros de parafusos físicos (momento, energia cinética e densidade de energia) foram avaliados. Os indicadores clínicos da função cerebral foram registrados após o atordoamento (GR), após serem içados (HO) e no trecho sangrante (BL). Parâmetros de parafusos físicos (velocidade do parafuso, momento, energia cinética, densidade de energia e densidade seccional) foram significativamente maiores (P <0,001) para PCB. A necessidade de dois ou mais tiros foi mais frequente para NPCB (210-220 psi; 29% vs. 12%, P <0,001). Bovinos foram mais propensos a colapsar no primeiro tiro com PCB (190 psi; 99%) em comparação com NPCB (91%; P <0,002), o que pode ser atribuído aos valores mais altos dos parâmetros físicos do parafuso. Incidência de rotação do globo ocular (5% vs. 1%) e comportamento de endireitamento (7% vs. 1%) foram maiores (P <0,001) para NPCB (210-220 psi) na GR do que na PCB. O NPCB com 210-220 psi teve uma maior freqüência de resposta à estimulação da narina (2% vs. 0%; P <0,001) do que a PCB. Respiração rítmica foi mais freqüentemente encontrada para NPCB com 210-220 psi em GR, HO e BL. Portanto, a PCB com 190 psi foi mais eficaz para garantir a inconsciência no gado.
