  2. Sow behaviour towards humans during standard management procedures and their relationship to piglet survival

    Contributor(s):: Lensink, B. J., Leruste, H., Bretagne, T. de, Bizeray-Filoche, D.

    Piglet crushing remains a major problem in pig production and is partly related to sow behavioural traits. The sows' responses to the presence of humans around farrowing could partly contribute to piglet crushing through increased reactivity and getting up and lying down behaviour. The aim of the...

  3. The combined effects of milking frequency and feeding level on dairy goat welfare and milk emission characteristics in late lactation

    Contributor(s):: Komara, M., Giger-Reverdin, S., Marnet, P. G., Roussel, S., Duvaux-Ponter, C.

    This study investigated the combined effects of once-daily milking and feeding level (ad libitum or adjusted) on goat welfare and milk emission characteristics in late lactation. Forty dairy goats housed in individual pens were managed under twice-daily milking and fed ad libitum during a...

  4. A review of environmental enrichment for pigs housed in intensive housing systems

    Contributor(s):: de Weerd, H. A. van, Day, J. E. L.

    This paper critically reviews the literature concerning environmental enrichment for weaner, grower and finisher pigs housed in intensive (indoor) production systems. The thesis of our review is that successful enrichment should meet four criteria of success: (1) it should increase...

    Contributor(s):: Calamari, L., Calegari, F., Stefanini, L.

    Two experiments were carried out on 56 lactating dairy cows in an experimental free stall barn comparing four different lying surfaces: straw bedded pack (ST), rubber mat (RM), mattress (MA) and sand (SA). In the first experiment (26 days) cows were allowed to choose between free stalls with each...

  6. Effects of social learning on foraging behaviour and live weight gain in first-season grazing calves

    Contributor(s):: Hessle, A. K.

    When livestock are turned out to semi-natural grasslands, an effective onset of grazing is important both for animal productivity and for defoliation of the sward, which preserve the biodiversity of the vegetation. The aim of this study was to investigate whether foraging behaviour of naive...

  7. Estimates of genetic parameters for hunting performance traits in three breeds of gun hunting dogs in Norway

    Contributor(s):: Brenoe, U. T., Larsgard, A. G., Johannessen, K. R., Uldal, S. H.

    Breeding of gun dogs in Norway is partially based on field hunting tests. Dogs are tested individually and performances of seven traits are judged by scores from 1 to 6. The traits are hunting eagerness, speed, style, independence, seeking width, ability to work in the field and cooperation. In...

  8. Physiological and behavioural responses of cows from two beef breeds submitted to different suckling strategies

    Contributor(s):: Alvarez-Rodriguez, J., Sanz, A.

    This experiment was designed to study the effects of avoiding calf contact and genotype on the metabolic, behavioural and reproductive traits of beef cows during lactation. Fifty-two multiparous cows, 25 Parda de Montana (PA) and 27 Pirenaica (PI), fed at maintenance were assigned from the day...

  9. The effect of different degrees of 'positive' human-animal interaction during rearing on the welfare and subsequent production of commercial dairy heifers

    Contributor(s):: Bertenshaw, C., Rowlinson, P., Edge, H., Douglas, S., Shiel, R.

    A 3-year study tested the hypotheses that brushing each heifer for 5 min per week in the weeks preceding calving (long term positive treatment: PT) while the heifers were unrestrained, is sufficient to improve subsequent parlour behaviour and production, and this could be influenced by the extent...

  10. Too hungry to learn? Hungry broiler breeders fail to learn a Y-maze food quantity discrimination task

    Contributor(s):: Buckley, L. A., McMillan, L. M., Sandilands, V., Tolkamp, B. J., Hocking, P. M., D'Eath, R. B.

    Choice tests may aid determining whether qualitative dietary restriction improves the welfare of feed-restricted broiler breeder chickens (Gallus gallus domesticus). However, hunger-stress may reduce competency to choose by impairing learning. The effect of chronic feed restriction on the ability...

  11. Assessment of animal welfare in 80 dairy cow herds in cubicle housing # animal health and other animal-related parameters

    Contributor(s):: Rouha-Mulleder, C., Palme, R., Waiblinger, S.

    Introduction: With growing concerns about farm animal welfare (e.g. by consumers; WILDNER, 1998), knowledge about the actual situation with regard to animal welfare on farms is important. Valid assessment of animal welfare requires the use of animal-based parameters, while environmental...

  12. Effect of different litter material on performance and behavior of broiler chickens

    Contributor(s):: Toghyani, M., Gheisari, A., Modaresi, M., Tabeidian, S. A.

    Two experiments were conducted to investigate the effects of alternative litter materials on growth performance and behaviors of broiler chicks. Chicks were raised from 1 to 42 days of age, during the summer with an average temperature of 31 degrees C. In experiment 1, three hundred broilers...

  13. Effects of intra- and interspecific competition on diet, growth and behaviour of Labeo calbasu (Hamilton) and Cirrhinus cirrhosus (Bloch)

    Contributor(s):: Rahman, M. M., Verdegem, M.

    Effects of intra- and interspecific competition on diet, growth, grazing, swimming, resting and social behaviour of two carps calbasu (Labeo calbasu) and mrigal (Cirrhinus cirrhosus) were examined in single and mixed species treatments. Three treatments (tanks with 4 L. calbasu, 4 C. cirrhosus or...

  14. Influence of weaning age and an experimental Haemonchus contortus infection on behaviour and growth rates of lambs

    Contributor(s):: Schichowski, C., Moors, E., Gauly, M.

    Four groups of 20 lambs each, differing in weaning age (6 or 13 weeks) and infection with Haemonchus contortus (infection after weaning or simultaneous to weaning), were observed and compared regarding the behaviour before, during and after these procedures. Furthermore the influence on...

  15. Swimming, grazing and social behaviour of rohu Labeo rohita (Hamilton) and common carp Cyprinus carpio (L.) in tanks under fed and non-fed conditions

    Contributor(s):: Rahman, M. M., Verdegem, M. C. J., Nagelkerke, L. A. J., Wahab, M. A., Verreth, J. A. J.

    Fish behaviour was monitored in 1-m2 tanks each stocked with three 67-g rohu (Labeo rohita). In addition, 80-g common carp (Cyprinus carpio) were stocked at 0, 1 or 2 fish per tank. All tanks were fertilized prior to stocking to stimulate natural food production. In addition, half of the tanks...

    | Contributor(s):: Froberg, S., Gratte, E., Svennersten-Sjaunja, K., Olsson, I., Berg, C., Orihuela, A., Galina, C. S., Garcia, B., Lidfors, L.

    The aim of this study was to evaluate the effects of restricted suckling (RS) in Holstein cattle on the weight gain, health and behaviour of calves and on udder health and milk let-down in cows compared to artificial rearing (AR). The study was conducted in Mexico. The 27 cows with calves were...

  20. Physiological and behavioural responses of laboratory rats housed at different tier levels and levels of visual contact with conspecifics and humans

    | Contributor(s):: Cloutier, S., Newberry, R. C.

    Laboratory rats are typically housed in clear or opaque cages on multi-tiered racks. Clear-walled cages allow a view of the room and facilitate visual social contact with neighbouring rats but may induce anxiety due to lack of visual cover. We hypothesized that degree of visibility of humans and...
