Very little is known about the effects of an organic or conventional diet on animal physiology and health. Here, we report the effect of contrasting crop protection (with or without chemosynthetic pesticides) and fertilization (manure or mineral fertilizers) regimes on feed composition and growth and the physiological parameters of rats. The use of manure instead of mineral fertilizers in feed production resulted in lower concentrations of protein (18.8 vs 20.6%) and cadmium (3.33 vs 4.92 μg/100 g) but higher concentrations of polyphenols (1.46 vs 0.89 g/100 g) in feeds and higher body protein (22.0 vs 21.5%), body ash (3.59 vs 3.51%), white blood cell count (10.86 vs 8.19 × 10³/mm³), plasma glucose (7.23 vs 6.22 mmol/L), leptin (3.56 vs 2.78 ng/mL), insulin-like growth factor 1 (1.87 vs 1.28 μg/mL), corticosterone (247 vs 209 ng/mL), and spontaneous lymphocyte proliferation (11.14 vs 5.03 × 10³ cpm) but lower plasma testosterone (1.07 vs 1.97 ng/mL) and mitogen stimulated proliferation of lymphocytes (182 vs 278 × 10³ cpm) in rats. There were no main effects of crop protection, but a range of significant interactions between fertilization and crop protection occurred.
关于有机或传统饮食对动物生理和健康的影响，人们知之甚少。在这里，我们报告了对比作物保护（使用或不使用化学合成农药）和施肥（粪肥或矿物肥料）对大鼠饲料成分、生长和生理参数的影响。在饲料生产中使用粪肥代替矿物肥料会导致蛋白质（18.8 对 20.6%）和镉（3.33 对 4.92 μg/100 g）浓度降低，但多酚（1.46 对 0.89 g/100 g）浓度升高；饲料中体蛋白（22.0 对 21.5%）、体灰分（3.59 对 3.51%）、白细胞计数（10.86 对 8.19×10³/mm³）、血浆葡萄糖（7.23 对 6.22 mmol/L）、瘦素（3.56 对 2.78 ng/mL）、胰岛素样生长因子 1（1.87 对 1.28 μg/mL）、皮质酮（247 对 209 ng/mL）和淋巴细胞自发增殖（11.14 对 5.03×10³ cpm）较高，而血浆睾酮（1.07 对 1.97 ng/mL）和有丝分裂原刺激的淋巴细胞增殖（182 对 278×10³ cpm）较低。作物保护没有主要影响，但施肥和作物保护之间存在一系列显著的相互作用。
