研究旨在探讨在哺乳犊牛饲料中添加不同水平的硒,直接作用于皱胃时犊牛免疫系统的增强和生长性能的提高是否优于瘤胃。选用75日龄的新生犊牛(荷斯坦×新泽西州)30头,随机分配成3组:C组为对照组(不补充硒,硒源只来源于牛奶中);Se A组为皱胃0.80 mg·头-1·d-(1注射);Se R组为瘤胃0.80 mg·头-1·d-(1口服)。犊牛在30日龄时,两个试验组犊牛血液中硒的浓度极显著高于对照组(P=0.001)。两个试验组犊牛的巨噬细胞的吞噬活性高于对照组,其中Se A组极显著高于Se R组(P=0.007)。在犊牛30日龄期间,各组间犊牛的中性粒细胞和血细胞比容的氧化活性无显著差异。30日龄Se R组的哺乳犊牛的干物质采食量(P=0.059)和胸围增益(P=0.059)均显著高于Se A组(P<0.01)。与对照组相比,补充硒可有效提高犊牛的饲料转化率(P=0.075)。30日龄各组犊牛的体增重(P=0.059)、高度和长度均无显著差异。在75日龄时,补充硒的犊牛的血液中硒含量(P=0.079)和胸围(P=0.088)呈现增加的趋势。在哺乳犊牛的牛奶中补充有机硒0.80 mg可增加血清中硒含量,并增强其30日龄时的免疫机能。对犊牛皱胃补充硒其免疫反应优于对犊牛瘤胃的补充。此外,补充硒可减少对动物生产中腹泻。补硒不能哺乳犊牛生长,但可以提高哺乳期间的免疫功能。

We analyze the two flavor version of the Nambu-Jona-Lasinio model with a repulsive vector coupling (GV), at finite temperature and quark chemical potential, in the strong scalar coupling (Gs) regime. Considering GV = 0, we review how finite Nc effects are introduced by means of the Optimized Perturbation Theory (OPT) which adds a term to the thermodynamical potential. This 1/ Nc suppressed term is similar to the contribution obtained at the large-Nc limit when GV ≠ 0. Then, scanning over the quark current mass values, we compare these two different model approximations showing that both predict the appearance of two critical points when chiral symmetry is weakly broken. By mapping the first order transition region in the chemical potential-current mass plane, we show that, for low chemical potential values, the first order region shrinks as μ increases but the behavior gets reversed at higher values leading to the back-bending of the critical line. This result, which could help to conciliate some lattice results with model predictions, shows the important role played by finite Nc corrections which are neglected in the majority of the works devoted to the determination of the QCD phase diagram. Recently the OPT, with GV = 0, and the large-Nc approximation, with GV ≠ 0, were compared at zero temperature and finite density for one quark flavor only. The present work extends this comparison to finite temperatures, and two quark flavors, supporting the result that the OPT finite
