The assessment of the nutritional value of plants rich in condensed tannins (CT) stems from the models predicting the normal nutritional value. In order to verify the effects, this study compares the nutritional value of chicory (cychorium intybus), sainfoin (onobrychis viciifolia) and lotus (lotus corniculatus) obtained with data determined using animals (in vivo, in sacco)…
A low feed intake during the first days after weaning predisposes piglets to diarrhea. Adding expensive milk byproducts such as whey or skim milk powder to their feed are used to stimulate their appetite. The effect of a diet which consisted of a piglet feed containing no milk byproducts supplemented with whole cow’s milk on…
In order to check and improve the prediction of their nutritive value, 12 maize silages were studied as a supplement to the previous trials. Two varieties (Amadeo and LG32,52) were harvested at three different stages over the course of two years. The silages were studied to determine organic-matter digestibility (OMD) in the case of sheep,…
Due to the lack of country-specific data, the so-called IPCC default values are often taken for calculating greenhouse gas budgets. The default value to be applied for Switzerland for the ultimate methane (CH4) production capacity (B0) of slurry amounts to 240 l CH4/kg volatile solids (VS). In the present study, slurry from 64 dairy farms…
In Switzerland, some farms are using chemical preservatives in order to preserve moist hay. Detailed knowledge of the DM-content as well as the correct dosage are important for the success. In a trial, the efficacy of the preservative Selko Heu was investigated with hay of two different dry matter contents and three different dosages. As…
Soiled traffic floor surfaces in cattlehousing systems represent plane sources for ammonia emissions. For emission-reduction purposes, the influence of the gradient on the drainage behaviour of water was quantified on a pilot-plant scale for seven different traffic surfaces. The surfaces were uniformly soiled with a mixture of excrements and urine. Measuring parameters were the duration…
The quality of a feedstuff is not only defined by the various nutrient contents, or by its composition in terms of raw materials, or its digestibility or its palatability, nor even by its appearance or sensory characteristics, but also by its hygienic status. This article presents a way of assessing the microbiological quality of feedstuff,…
Crossings between horses and donkeys are in nature possible and are used as mules or hinnies in agriculture. Other types of crossings are rare and scarcely investigated. Systematic experiments are only allowed with special agreements and are very time consuming and costly and therefore rare. In this report crossings between horse, Przewalski and donkey are…
Climate change is leading to higher temperatures across Switzerland, increasing the risk of heat stress in livestock. Analyzing a «Temperature-Humidity Index» at various locations, it could be shown that the risk for dairy cows already grew substantially on a daily average over the past 30 years, whereas the maximum of the index did not change…
The year 2010 was declared by the United Nations as the International year of biodiversity. During that year, the Swiss Sheep Breeding Association made herd book data of its four largest breeds available for genetic diversity analyses. Those were Brown Headed Meat Sheep (OX; n=10 858), Black Brown Mountain Sheep (BNP; n=10 964), Valais Black…
Milk output per hectare of forage surface area is a means of measuring the efficiency of dairy production. The aim of this study is to identify which factors are decisive in the variation of surface-area productivity practised in the canton of Fribourg in Switzerland. The analysis is based on a survey of 266 dairy farms…
The aim of this study was to investigate a possible relationship between acid-base parameters in urine before parturition and the calcium level in blood shortly after parturition. Hundred dairy cows kept under identical feeding and housing conditions were monitored. The diet was based on grass and corn silage and hay ad libitum. Urine samples were…
The objective of the study was to compare, within pasture-based seasonal-calving systems, the performance of Swiss Holstein-Friesian, Fleckvieh and Brown Swiss dairy cows with New Zealand Holstein-Friesian dairy cows. Within the trial, the two Holstein breeds had the best production performance, whereas the Fleckvieh cows had optimal reproductive performance. Swiss Holstein cows were efficient milk…
When using efficient silage additives the aerobic instability can be reduced. The Liebefeld-Posieux Research Station ALP tested the silage additive Schaumasil supra NK meant for improving the aerobic stability of maize silages. In addition to a negative control without additives, a positive control with Luprosil was taken into account. The trials were conducted with silage…
In a «System comparison of milk production in Hohenrain » two dairy cattle herds on an identical land area were compared over three years in different production systems. Higher individual livestock yield and intensive cowshed feeding characterised the «cowshed herd» system, while the «pasture herd» was managed with permanent access to pasture and seasonal calving…
In the years 2008 to 2010, in the project «System comparison milk production Hohenrain», two different milk production systems were compared: a pasture based system versus an indoor feeding system with a mix ration of grass and maize silage. In the present paper the results of milk quality and seasonal milk production were investigated. The…
The aim of this study was to compare barn-keeping (BK) to pasture-based-keeping (PK) systems in dairy farming. We established two herds which were kept under the same conditions and with an equal agricultural area (AA) on the same experimental farm from 2008 to 2010. The BK herd consisted of 12 Swiss Holstein-Friesian and 12 Brown…
Preservation of moist hay with preservatives In order to be able to stock hay without spoilage, it must be dry enough. The use of preservatives / additives at baling of moist hay is an alternative. In two trials, the efficacy of two products, Schaumasil supra NK and KRONI 909.01 Stabisil, was investigated with hay with…
The objective of the study was to compare, within pasture-based seasonal-calving systems, the production and reproduction performances of Swiss Holstein-Friesian (CH HF), Fleckvieh (CH FV) and Brown Swiss (CH BS) dairy cows with New Zealand Holstein-Friesian (NZ HF) dairy cows, taken as reference for such systems. From 2007 to 2009, NZ HF cows were paired…
As most European countries, Switzerland has signed the Gothenburg Protocol to abate acidification, eutrophication and ground-level ozone. The protocol puts pressure on Swiss livestock producers to implement measures to reduce their ammonia emissions. Dietary modifications (optimization of crude protein concentration) will affect, as a begin-of-pipe measure, all emission stages from barn to field. The aim…
Switzerland is a country of grasslands. The effective use of this resource is essential for the Swiss dairy industry. To ensure this, efficient milk production systems and cows suited to these systems are necessary. The existence of interactions between genotype and environment when comparing contrasting conditions of production raises the question of the suitability of…
The Eringer cattle breed is a local breed of Swiss origin. The goal objective of this study was to analyse the development of genetic diversity from 1993 to 2007 using pedigree information. In addition, 128 Eringer cows were genotyped for through the Illumina 50k Illumina beadchip method and, using this genome-wide marker information, the genetic…
Ruminant activity is considered an important non-invasive measurable parameter for the early identification of metabolic problems in ruminants. Traditional rumination sensors have drawbacks, particularly when used in the cowshed area. The newly developed ART rumination sensor incorporates a noseband sensor comprising a fluid-filled tube and pressure sensor, a data logger, and the evaluation software. The…
Der Strukturwandel in der Schweizer Landwirtschaft, unter anderem der sinkende Milchpreis, veranlasst viele kombinierte Milchvieh-Ackerbaubetriebe zur Aufgabe der Milchproduktion. Dadurch werden die Kunstwiesenjahre innerhalb der Fruchtfolge nicht mehr benötigt, was negative Konsequenzen auf die biologische Stickstofffixierung (Weissklee), die Bodenstruktur und die Erosion haben kann. Die Fleischproduktion auf Kunstwiesenflächen während der Vegetationsperiode könnte ein möglicher Betriebszweig…
Nine gilts with an initial body weight (BW) of 80 kg were fed a diet contaminated with 2 mg/kg deoxynivalenol (DON) and 0.4 mg/kg zearalenone . Their daily weight gain until 100 kg BW was reduced in comparison to the nine control animals fed the uncontaminated diet. The mycotoxins neither influenced the age at the…
The goals of these trials were to investigate the effects of different dietary amino acid concentrations and valine:lysine ratios on piglet performance and health. Two 4-week trials with 90 weaned piglets each were conducted. Both trials were set up as a block design with 3 treatments and 6 replicates per treatment (a total of 18…
Scarring of the Outside Flat’ is the expression used in Switzerland to designate a quality defect appearing on the main muscle used to produce dried meat, the Biceps femoris or gluteobiceps. This problem, already known for decades and now clearly increasing, was still yet not explained. This led the inter-branch organisation for meat to award…
