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…
This article shows the difference in fat and fatty acid levels between preserved forages and grass. Grass was harvested from the same plot of land at two different stages (30 days apart) over three years and stored using six different processes. 42 samples were analysed by extraction using petroleum ether for fat and by gas…
Since some years, hay in horse diets has been partly replaced by silage with high dry matter contents, also known as haylage. There remain still some questions concerning the stability of haylage as well as the conditions during storage. In this context, the influence of dry matter (DM)-content and the addition of (oder a) silage…
Agroscope Liebefeld-Posieux Research Station ALP investigated the efficacy of the silage additives Fireguard and Sil-EM for the improvement of aerobic stability in maize silages. Beside a negative control without additives, a positive control with Luprosil was also tested. The trials were conducted with maize cv. Amadeo, harvested at 32 % and 40 % dry matter…
The use of an electronic labelling system for livestock enables the animals to be automatically identified with stationary antenna systems. In the present study, the recognition system for reading individual transponders from a group (bulk reading), already in use in other industrial sectors, was tested with fattening pigs. To evaluate different antenna systems, transponders mounted…
