No presente trabalho objetivou-se mensurar o rendimento de culturas anuais e forrageiras no sistema de integração lavoura-pecuária nas condições dos cerrados do Piauí. Os dados foram obtidos na Fazenda Nova Zelândia situada no município de Uruçuí, PI. Foram estabelecidas unidades demonstrativas e mensurados os rendimentos de milho e forrageiras no Sistema Santa-Fé durante a safra de 2006, 2007 e 2008, numa área de 80, 200, 200 ha, respectivamente. O rendimento do milho nos referidos anos foi de 5.400, 5.400, 7.800 kg/ha e média de 6.200 kg/ha, enquanto que o rendimento das forrageiras foi de 43, 32, 20 t MV/ha e média de 31,6 t MV/ha. Estes resultados permitem recomendar o sistema de integração lavoura-pecuária nos cerrados piauienses. |

Abstract: L-carnitine is an antioxidant and ?-oxidation stimulator substance commonly used to improve metabolic performance of oocytes and embryos in in vitro systems. However, few studies have evaluated its beneficial effects in embryos produced in vivo. This study aimed to evaluate the effect of L-carnitine supplementation into vitrification or warming solutions on the post-warming character of day 6?7 in vivo-produced ovine embryos. L-carnitine (3.72 mM) was added to vitrification (Experiment 1) or warming solutions (Experiment 2). In experiments 1 and 2, the embryos were vitrified using straw and cryo-tip protocols, respectively. In vitro culture (IVC) of warmed embryos was performed for 72 h in order to evaluate survival rates, reactive oxygen species (ROS) levels, total cell number (TCN), number of apoptotic cells, apoptotic index evaluation, and gene expression analysis of carnitine palmitoyltransferase I and 2 (CPT1 and CPT2), carnitine O-acetyltransferase (CrAT), and peroxiredoxin-1 (PRDX1). In experiment 1, survival rate, ROS levels after 24 h of IVC, total cell number at 24 h and 72 h, apoptotic cells and apoptotic index at 72 h of IVC were similar in embryos vitrified in medium supplemented with LC or not. Gene expression analysis showed no differences in CPT1 and CPT2mRNA relative abundance in embryos of both experiments compared to fresh embryos (FE); however, CrAT was downregulated (p < 0.05) in C1, and PRDX1 was downregulated (p < 0.05) in both the control (C1) and L-carnitine (LC1) groups, compared to FE. Moreover, CrAT and PRDX1 were upregulated (p < 0.05) in C2, and CrAT was downregulated (p < 0.05) in LC2, in relation to FE. Although the short-term LC supplementation at 3.72 mM did not improve survival, and quality parameters of in vivo-produced ovine embryos, it could affect their quality at a molecular level. In conclusion, further investigations with different concentrations of LC and tools are needed for improvement of the efficiency of these strategies.
