To evaluate pain responses to intratesticular and subscrotal injection of three local anaesthetics and their efficacy during castration a randomized controlled study was conducted. In groups of 20 piglets, procaine (2%), lidocaine (2%), or mepivacaine (2%) were administered subscrotal and intratesticularly in two different dosages: 0.5 mL of the or...
Bei der Schweineschlachtung können Prozessfehler in Bezug auf die Betäubung und/ oder Entblutung zur Folge haben, dass einzelne Tiere zwischen Beginn der Betäu-bungswirkung und Eintreten des Todes das Bewusstsein wiedererlangen und ggf. in empfindungsfähigem Zustand schmerzhaften weiteren Schlachtarbeiten ausgesetzt werden. Das ist ethisch inakzept...
1. Sufficient floor space is a fundamental precondition for poultry to perform normal behavioural patterns. To calculate and determine stocking densities, it is essential to know the absolute minimum surface area required by any given animal (body space). Additional space is required for characteristic behaviours (behavioural space) and for adequat...
Logistic maps (LM) expose a well studied phenomenom. The recursive call of the LM with
f (x n) = τ x n−1 (1 − x n−1) with {τ ∈ R | (3.83, 4.0]}; {x ∈ R | (0, 1)} (1)
will get into chaotic state at 0 < x < 1 and 3.56995 < τ < 3.82843 or 3.82843 < τ <= 4.0
In a theoretically infinite space of real numbers the LM will conserve the chaotic state ad i...

Legal requirements on space and dimensions regarding furnished cages and alternative systems in laying hen husbandry are subject of constant discussion. Further knowledge about basic measures of the hens might help to come to reasonable results in the future. Digital images of Lohmann Selected Leghorn (LSL) and Lohmann Brown (LB) laying hens, house...
Summary: The available floor space has a strong impact on the execution of various behav-iours of laying hens. Presently, in Germany detailed requirements on the housing of pullets are insufficient. In order to get a first approximation, the floor space covered by pullets was determined by the colour contrast planimetric method KobaPlan. The measur...

1. Laying hens in two aviary flocks of 1250 females and 12 males were investigated to determine if hens used the same roosting site more often than expected by chance and whether hens that roost next to each other for two consecutive nights (close groups) had fewer agonistic interactions than hens roosting far away from each other (distant groups)...

In 2008 i started automating examinations at the Tierärztliche Hochschule Hannover by developing a paper based answering system that is evaluated using image analysis. From that i developed iExam as a platform and examination system, that handles multimedia in any question format. iExam was presented at different occasions and used successful in te...
Stocking density is one of the most disputed criteria in broiler production. But little is known about the real floor space covered by a sitting or standing broiler. This paper gives realistic figures on the floor space covered by broilers in various body positions, age and weight in the course of fattening. The measurements were carried out by the...
Space allowance for laying hens is one of the most disputed criteria of modern laying hen husbandry. Fast and cheap methods to achieve reliable data about the space occupied by laying hens are missing. This studie is based on a method, that can be used to measure the space ocupied by laying hens using digital images from above. 100 hens were photog...
Feather pecking and cannibalism are serious problems in keeping Moscovy ducks. Prevention of feather pecking by regularly applied beak and claw trimming are increasingly criticised by the public. The recommendation of the Council of Europe (COE) for the keeping of Muscovy ducks in farming systems calls for environmental enrichment including water f...
Although several studies show that fresh wood shavings (FW) are not well-suited as dustbathing substrate for laying hens, little is known about the suitability of wood shavings used as litter in non-cage systems for several weeks (used wood shavings, UW) and the effect of different substrate depths. We compared FW and UW at two different depths of...
This literature review gives information about important behaviour patterns concerning feeding, reproduction and dust bathing of laying hens kept in aviary systems. The behaviour of hens in aviaries is compared to the behaviour of hens living under "close to natural" conditions. Feeding behaviour can be performed to a great extent in aviaries. The...
This literature review gives information about important behaviour categories of laying hens kept in aviary systems. Based on current knowledge, the differences in behaviour of hens in aviaries compared to the behaviour of hens living under "close to natural" conditions are assessed quantitatively and qualitatively. The focus of this first review i...
The wild ancestors of the domestic pekin and muscovy ducks are anatomically, physiologically and behaviourally well adapted to living on and at the water. The domestic ducks kept for fattening purposes still show clear preferences for open water and make use of water for foraging and feeding, drinking, for general exploration, locomotion and preeni...

As of 1 September, 2001 existing legislation regulating outdoor dog husbandry is replaced by the domestic dog welfare directive of 2 May, 2001. The new directive applies to details of housing and breeding of dogs kept indoors and as domestic companions. Thus, minimum requirements for housing, care and feeding now apply to the great majority of priv...
Recent developments in the European and national legislation regarding minimum standards for the keeping of laying hens will be causing changed conditions for egg production in the medium term. Enriched cages shall allow hens to better fulfill their needs than traditional battery cages. More space for the stretching of wings and legs, perches for r...

A device (PIGLIFT) was developed for careful conveyance and fixation of pigs for electrical stunning combined with recumbent bleeding. Special emphasis was put on critical points, such as low stress in the fixation-device, possibility to place the electrodes correctly and easy operation. The PIGLIFT was tested under practical conditions, the reacti...
Mobile slaughter is commonly discussed as alternative method to slaughter avoiding transportation stress in slaughter animals. In 1994 mobile slaughter became part of the coalition-contract between the two major parties, SPD and GRUNE, in the Department HESSEN. In the article the actual principles, problems to cope with EU-legislation and hygiene-s...
It is reported on the fatal accident of a horse due to a cross-beam too low above the door of the stable, in which the animal suffered several skull fractures and a tear of the musculus longus capitis from the base of the skull. The aim of this article is, to supply a contribution to the establishment of minimal requirements for the housing of hors...
The importance of correct handling of slaughter animals at the farm, on transport and in the slaughterhouse is described. The status of animal welfare in slaughterhouses, the relations between animal welfare, preslaughter animal condition and meat quality are discussed. Possibilities of better information exchange by integrated quality systems are...
Wenn zwischen mehreren Handlungsmöglichkeiten zu entscheiden ist, trifft oft eine Binsenweisheit den Nagel auf den Kopf: "Wer die Wahl hat, hat die Qual!" Ethische Dilemmata infolge von Konflikten zwi-schen ethischen Prinzipien können eine Entscheidung ebenso erschweren wie die Schwierigkeit, zwischen vielen Übeln das kleinste auszumachen. Eine str...

Working on Open Field Test (OFT) animal tracking, i recently noticed that there is actually -no- some )* "ground truth" published about the "normal" behavior of laboratory mice and rats in OFT. Being aware of the big influence of the specific environment in which OFT is done, nonetheless it should be possible to detect some kind of common characteristics in the animals behavior. And this may help researchers in future to evaluate their testing environment and improve their experimental settings to get more reliable results.
If you like to share video recordings of naive mice/rats for this purpose, please contact me via researchgate
)* UPDATE: there is some data at Rat Genome Database - rgd.mcw.edu . see below for the actual access information.
)* UPDATE: there is data on mice too: see Marin Jukic's answer below for the Mouse Phenome Database phoneme.jax.org
