| Sand, compost and recycled manure solids are used on some commercial farms as bedding material in cubicles as an alternative to conventional straw mattresses or soft rubber mats. The aim of the present studies was to evaluate these bedding materials in dairy-cow cubicles in terms of process engineering, animal welfare, hygiene, work economics and farm management. From an animal welfare and hygienic point of view, these mentioned materials are recognized as safe. Where sand is used as bedding, the working-time requirement for cubicle maintenance is comparable to that for soft rubber mats; where compost and recycled manure solids are used, it is comparable to that for straw mattresses. The material costs for sand are high, whilst those for compost... |

| Fazit: Die durchgeführten Versuche zeigen, dass durch die Biogasgärung die Keim-fähigkeit von Samen beeinträchtigt wird und somit die Verbreitung von Unkrautsamen vermindert werden kann. Neben Faktoren wie Mikroorganismenaktivität, Schadgasen, die beim Abbau von organischer Substanz entstehen, und dem Samenfeuchtig-keitsgehalt spielten hierbei vermutlich vor allem die Temperatur des Substrats und die Verweildauer der Samen in der Biogasanlage eine Rolle. Berücksichtigt man dies bei der Betriebsweise einer Biogasanlage, kann man davon ausgehen, dass der Unkraut-druck durch die Verbreitung der Unkrautsamen über die Gülleausbringung gesenkt werden kann. |

| There was a lack of up-to-date statistics on the working time requirements in suckler cattle farming under Swiss production conditions. A combination of final and causal methods for recording working time was used to determine working-time input and working-time requirements, to survey influence variables and draw up working-time models using a model calculation system. The total working time spent on suckler cattle farming varied between 28 and 120 hours per cow per year, with an average of 66 hours per cow per year. Over half of this time was spent on routine work, 20 % on management work, 19 % on other non-daily work and 3 % on direct marketing, animal care and animal handling, respectively. The larger the herd size, the lower the time spent on... |
