These days, especially in organic piglet production, it is necessary to reduce the production costs to be competitive on the market. A large proportion of the production costs are caused by labor and construction costs to ensure a high level of animal welfare. The farrowing pen of Wels, currently existing in prototype form, was designed to fulfill organic farming requirements, improve animal welfare, and minimize the costs for construction and labor. The housing system is characterized by four separate functional areas: the lying area, the excretion and moving area, the feeding area for the sow, and a piglet nest. To identify the working time requirements of routine and special tasks, a time study, based on the work element method and an electronic time recording system (ortim b3) (a Pocket PC with time recording software), was conducted. The influencing variables and the time measurements were collected by directly observing work processes in the farrowing unit, which had 5 farrowing pens, over a period of 21 days at the “LFZ Raumberg Gumpenstein.” The data were descriptive and statistically analyzed to obtain planning data on the element basis. The time requirement was modeled according to the related task and in total over the suckling period. The routine tasks consisted in transporting the feed to the pen, feeding the sows, monitoring the sows and piglets, mucking out the dung corridor with a tractor and sprinkling straw in it, as well as filling up the hay rack. The labor input was 3.99 AKmin per sow and day in total. The special tasks included inoculating the piglets, marking with ear tags, castrating the male piglets, cleaning the whole pen and the dung corridor, and preparing the farrowing pen for the next sows. Special work required 25.9 MPmin per sow over the keeping period of 21 days. The total working time requirements over the period of 21 days were 1.82 MPh per sow. Overall, the farrowing pen of Wels has low time requirements and can be seen as a good alternative to the existing organic pens. © 2013, Copyright E. Quendler et al.

Four different slurry application techniques (drag shoe = SH, drag hose = SC, chisel injector = D and deflector plate = PT) and one control plot (N = zero slurry) were tested on grassland within the catchment of lake Waging-Taching in order to investigate phosphorus losses into tile drains. Slurry (20 m 3.ha-1) was applied onto the grassland directly above tile drains. Then rainfall simulations were carried out, discharge from the tile drains was collected and analysed for phosphorus concentration (total P) and sediment concentration. The relation between sediment concentration and P concentration was almost linear for all tested slurry application techniques and P concentrations did not vary significantly within the tested variants (p > 0.05). However by pooling the near ground application techniques (SC, SH and D) a significant difference compared to PT could be shown (p = 0.03).

High application rates of farmyard manure on grasslands generally results in nitrogen (N) losses and a shift in N isotope composition. The aim of this study was to elucidate to which degree the 15N signatures of miscellaneous N pools at two different levels of management intensity may be used to reproduce the N level of various grassland farms in practise, i.e. beyond the control of experimental plots. We hypothesized that (i) higher δ15N values in soil, plant and animal samples can be found with intensified grassland farming and high N-input management, (ii) that the 15N signature originating from manure application is influenced by application technique and (iii) that it declines with increasing distance from stable to field. To test these hypotheses, we monitored different N pools on nine different farms (dairy, suckler, beef production) in grassland dominated regions of North Rhine-Westphalia, Rheinland-Palatinate (Germany) and Styria (Austria). Samples were taken from 0 to 5cm soil depth and aboveground biomass at each of five sub-sites on farm, as well as from feed components, fertilizers, and cattle product and tissue like milk, hair, faeces and urine.The results indicated a considerable variation in δ15N values of the top soil (1.47‰ to 7.91‰) and of harvested plant material (-2.18‰ to 6.79‰). On average, δ15N values of samples from high N-input grasslands were elevated by 2.8 delta units relative to those of low N-input grasslands. For the soil and plant samples, the δ15N values were thus closely correlated with the overall N balance as well as with stocking rate and fertilizer input (r2=0.71 to 0.85). Respective trends for the isotopic signatures in milk, hair and faeces were also evident but less apparent. Furthermore, low emission application techniques of organic fertilizer and increasing distances from the stable to the field exhibited lower δ15N values of top soils and plants, but only in the low input system. We conclude that high N-input on grassland farms systematically changes the δ15N values of soils and above ground biomass and thus also the N signature in animal tissues. Application of N isotope technique to these N pools thus allows for tracing back intensity of fertilizer management regardless of high natural δ15N variations in terrestrial environments. © 2013 Elsevier B.V.

The present article illustrates the economic results of an experiment, where different measures for an open-keeping and cultivating of extensive grassland areas were investigated. In this process suckler cows, sheep as well as technical procedures (mulching, substantial and energetic use) were employed. The mulching was the most reasonable measure costing € 128,- - € 205,- per ha for all slopes. The pasturing of the areas with sheep or cattle is most intensive in terms of costs and time (cattle: € 823,- - € 1,485,-; sheep: € 1,260,- - € 1,485,-). However, from an ecological lens this is the most convenient for cultivating and open-keeping. From a slope of more than 35% it is shown that none of the measures pays for itself and therefore a public support will be necessary for the preservation of an intact cultural landscape.

This article deals with the economical effects of a feed supplement with low-input dairy grazing systems based on a feeding experiment, which was figured out by the LFZ Raumberg-Gumpenstein. The aim of the project was to equalize possible disadvantages of the low-input grazing system - e.g. the decrease of the milk yield and the variability of the milk ingredients - by specific supplementary feeding. The results show that the pure low-input grazing system results in a milk yield of about 6,400 kg in the inner-alpine regions. This yields a profit margin of € 1,851. The additional feeding of maize-silage adds up in an additional benefit, whereas the addition of concentrate or hay leads to negative effects on the economical results. Every supplement reduces the intake of cheap pasture and therefore the portion of pasture in milk production. It can be shown that the maximisation of the grazing portion yields to a reduction of production costs. Furthermore it results in a more stabilized cost-situation in comparison to conventional producers.
