Abstract

This research project aimed to generate basic data for specifying the trace mineral requirements of Fleckvieh (German Simmental) bulls. Hence, the concentrations of the trace minerals iron (Fe), zinc (Zn), copper (Cu), and manganese (Mn) in the empty-body and body tissue fractions of growing Fleckvieh bulls slaughtered at 120-780 kg live weight were determined. Results were used to calculate trace mineral accretion rates. Fe and Zn represented the largest shares in the animals' bodies. The Zn accretion increased, while Mn accretion steadily declined during cattle growth. Fe accretion attained a maximum at 400 kg live weight. Cu accretion declined until 600 kg live weight and then increased slightly afterwards. The provided data may be used to adjust the recommendations with respect to the trace mineral requirements of growing Fleckvieh bulls.

生长中的Fleckvieh（德国西门塔尔）公牛空体和身体组织中的微量矿物质浓度和吸积率。

该研究项目旨在为确定Fleckvieh（德国西门塔尔）公牛的微量矿物质需求量提供基础数据。因此，在120-780屠宰的生长中的Fleckvieh公牛的空体和身体组织部分中微量矿物质铁（Fe）、锌（Zn）、铜（Cu）和锰（Mn）的浓度 kg活重。结果用于计算微量矿物的堆积率。铁和锌在动物体内所占比例最大。在牛生长过程中，锌的积累量增加，而锰的积累量稳步下降。Fe吸积在400时达到最大值 kg活重。铜的吸积一直下降到600 kg活重，之后略有增加。所提供的数据可用于调整关于生长中的Fleckvieh公牛的微量矿物质需求的建议。

期刊介绍： Archives Animal Breeding is an open-access journal publishing original research papers, short communications, brief reports, and reviews by international researchers on scientific progress in farm-animal biology. The journal includes publications in quantitative and molecular genetics, genetic diversity, animal husbandry and welfare, physiology, and reproduction of livestock. It addresses researchers, teachers, stakeholders of academic and educational institutions, as well as industrial and governmental organizations in the field of animal production.
