本试验旨在探究黄粉虫粉对良凤花肉鸡生长性能、屠宰性能、肉品质及肌肉风味物质含量的影响。试验选取1日龄的良凤花肉公鸡600只,随机分为5组,每组5个重复,每个重复24只,对照组饲喂基础饲粮,试验组分别饲喂用3%、5%、7%和9%的黄粉虫粉替代基础饲粮中部分豆粕的试验饲粮,试验期为70 d。结果表明:1)1~28日龄时,3%、5%组平均日采食量均极显著高于对照组、7%和9%组(P0.05)。3)3%和5%组腿肌的滴水损失率(24 h)均显著低于对照组和9%组(P<0.05)。4) 3%组肌肉中天门冬氨酸(Asp)、丝氨酸(Ser)、谷氨酸(Glu)、亮氨酸(Leu)、苏氨酸(Thr)、络氨酸(Tyr)、精氨酸(Arg)含量及风味氨基酸总量、甜味氨基酸总量、鲜味氨基酸总量、芳香族氨基酸总量、必需氨基酸(EAA)和总氨基酸(TAA)含量均显著或极显著高于对照组(P<0.05或P<0.01),组氨酸(His)含量极显著低于对照组(P<0.01);3%组肌肉中肉豆蔻酸(C14∶0)含量显著升高(P<0.05)。综上所述,在良凤花肉鸡饲粮中添加3%黄粉虫粉可提高肉鸡的生长性能,提高肌肉的保水性能,增强肉鸡肌肉的营养价值、风味、鲜味等特性,降低肌肉中的不良风味水平,从而提高其肉品质。本试验条件下,建议1~70日龄良凤花肉公鸡饲粮中黄粉虫粉的添加水平为3%。

Acta Geochimica 2018年第5期37卷 691-700页

作者： Chuanwei Zhu Wenning Lu Yongsheng He Shan Ke Hongjie wu linan Zhang State Key Laboratory of Geological Processes and Mineral Resources China University of Geosciences

Here we report iron(Fe) isotopic data of three pure Fe solution standards(IRMM-014, GSB Fe, and NIST3126a) and five widely used geological reference materials(RMs) from the United States Geological Survey and Geological Survey of Japan obtained on a Neptune Plus multi-collector–inductively coupled plasma–mass spectrometer(MC-ICP-MS) in our laboratory over the past 3 years. The instrumental mass bias was corrected by three independent methods: sample-standard bracketing(SSB),Ni doping + SSB, and ^(57)Fe–^(58)Fe double spike + *** reveal that both the Ni doping and double spike methods helped calibrate short-term fluctuations in mass bias. Collectively, almost all measurements of RMs yielded δ^(56)Fe within ± 0.05 of recommended values,provided that each sample was measured four times on MC-ICP-MS. For the first time, new recommended values for NIST SRM3126a are reported(δ^(56)Fe = 0.363 ± 0.006,2SE, 95% CI; and δ^(57)Fe = 0.534 ± 0.010, 2SE).

Much attention has been paid to the stoichiometry of carbon(C), nitrogen(N), and phosphorus(P) because of their significance for plant growth and climate change. However, other nutrients, such as sulfur(S), are often ignored. In this study, we analyzed the stoichiometry of N, P, and S in leaves of 348 plant species in China's forests. The results show higher N content and higher molar ratios of N/P and P/S in Angiospermae than in Gymnospermae. At the family level, Ulmaceae absorbed more N and P from soils than other families, and Cupressaceae absorbed more S than other families. In addition,except for bamboo and other tropical forests, leaf N and P content of China's forests generally increased from low to middle latitudes and then slightly decreased or plateaued at high latitudes. Plant ecotypes, taxonomic groups, environmental conditions, atmospheric S precipitation, and soil-available N and P significantly affected the distribution and stoichiometry of leaf N, P, and S in China's *** study indicates that China's forests are likely limited by P and S deficiencies which may increase in the future.

This study investigated the impact of topography and vegetation on distribution of rare earth elements(REEs)in calcareous soils using methods of single extraction and mass balance calculation. The purposes of the study were to set a basis for further research on the biogeochemical REE cycle and to provide references for soil–water conservation and REE-containing fertilizer amendments. The results show a generally flat Post-Archean Average Australian Shale—normalized REE pattern for the studied calcareous soils. REE enrichment varied widely. The proportion of acidsoluble phases of heavy REEs was higher than that of light REEs. From top to bottom of the studied hills, dominant REE sources transitioned from limestone in-situ weathering to input from REE-containing phases(e.g., clay minerals,amorphous iron, REE-containing fluids). Our results indicate that the REE content of calcareous soils is mainly controlled by slope aspect, while the enrichment degree of REEs is related to geomorphological position and vegetation ***, the proportion of acid-soluble phases of REEs is mainly controlled by geomorphological position.
