Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda
Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.
This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...
Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs
Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.
Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...
Dustbathing, pecking and scratching behaviours of laying hens in furnished cages are enhanced by the presence of rubber mats and litter distribution
Contributor(s):: Guinebretiere, M., Michel, V., Arnould, C.
Furnished cages for laying hens exist in a wide variety of sizes and designs and should be equipped to allow hens to express some of their behavioural priorities. European Council Directive 1999/74/EC stipulates that litter must be provided for pecking and scratching but the type of litter and...
Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas
Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de
Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...
Retracting inconclusive research: lessons from the Seralini GM maize feeding study
| Contributor(s):: Resnik, D. B.
In September 2012, Gilles-Eric Seralini and seven coauthors published an article in Food and Chemical Toxicology claiming that rats fed Roundup-resistant genetically modified maize alone, genetically modified maize with Roundup, or Roundup for 2 years had a higher percentage of tumors and...
Effects of stage of gestation at mixing on aggression, injuries and stress in sows
| Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.
Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...
Density-dependent diet selection and body condition of cattle and horses in heterogeneous landscapes
| Contributor(s):: Cornelissen, P., Vulink, J. T.
For some decades, grazing by cattle and horses is used as a management tool to achieve different nature management goals. For managers there are still questions to be answered about the effects of herbivore densities on their performance, vegetation development and biodiversity. This study...
Behavioural assessment of dental pain in captive Malayan sun bears ( Helarctos malayanus)
| Contributor(s):: Fleming, M., Burn, C. C.
Captive bears are prone to developing dental pathology for reasons including longevity in captivity, inappropriate diet, trauma, and stereotypical bar biting. If not detected, this can cause pain and suffering, with negative welfare consequences. As animals cannot verbally express feelings,...
Behaviour and welfare of veal calves fed different amounts of solid feed supplemented to a milk replacer ration adjusted for similar growth
| Contributor(s):: Webb, L. E., Bokkers, E. A. M., Engel, B., Gerrits, W. J. J., Berends, H., Reenen, C. G. van
Veal calves in Europe are typically fed large quantities of milk replacer and small amounts of solid feed, a diet known to lead to the development of abnormal oral behaviours in these animals. These abnormal oral behaviours are thought to be an indication of frustration, chronic stress, and...

A framework for the ethical analysis of novel foods: the ethical matrix
| Contributor(s):: Mepham, B.
The paper addresses the issue of how in democratic societies a procedure might be formulated to facilitate ethical judgements on modern biotechnologies used in food production. A framework for rational ethical analysis, the Ethical Matrix, is proposed. The Matrix adapts the principles described...
Coexistence of plants and coexistence of farmers: is an individual choice possible?
| Contributor(s):: Binimelis, R.
The introduction of genetically modified organisms (GMOs) in Europe has been characterized by controversy. In 2002, the European Union introduced the concept of "coexistence" as a compromise solution that, through the establishment of science-based technical measures, should allow the market to...
Environmental risks of pesticides versus genetic engineering for agricultural pest control
| Contributor(s):: Paoletti, M. G., Pimentel, D.
This paper discusses the environmental risks of pesticides as compared to the risks associated with the application of genetic engineering and biotechnology in agricultural pest, plant pathogen and weed control. It is suggested that in terms of environmental and public health impacts, pesticides...
