  1. A colostrum feeder for newborn lambs

    Contributor(s):: Fraser, D., Rushen, J.

    Newborn lambs were studied in 6 experiments to identify simple cues that elicit teat-seeking behaviour, and to incorporate these cues into a device that would guide lambs to find and suck from a colostrum bottle. Lambs were removed from the ewe before sucking and were observed for 10 min in a...

  2. A comparison of the calving behaviour of farmed adult and yearling red deer ( Cervus elaphus ) hinds

    Contributor(s):: Wass, J. A., Pollard, J. C., Littlejohn, R. P.

    Mortality of newborn red deer (Cervus elaphus) calves is a major concern on New Zealand farms, as perinatal losses average approximately 10% of calves born. Primiparous red deer (calving as yearlings) lose more calves than multiparous hinds (adults). We performed a study on yearling and adult red...

  3. A method of animal identification in studies on multisuckling behaviour

    Contributor(s):: Edmunds, J.

  4. A note on differences in nursing behaviour on pig farms employing individual and group housing of lactating sows

    Contributor(s):: Silerova, J., Spinka, M., Sarova, R., Slamova, K., Algers, B.

    The sow nursing behaviour may be affected by housing environment. So far, studies have focused on within-farm experimental comparisons, but data comparing nursing behaviour in a sample of commercial farms using different housing systems are lacking. This study had the following goals: (I) To...

  5. A note on nursing termination and resting behaviour of suckling piglets

    Contributor(s):: Petherick, J. C.

    Observations were carried out on 8 Large White x Landrace sows and their litters housed in either large straw-bedded pens, or conventional farrowing pens. The animals were observed for periods during the 8 days following parturition. Sows in the straw-bedded pens had built nests into which the...

  6. A note on the effects of additional sow gruntings on suckling behaviour in piglets

    Contributor(s):: Kasanen, S., Algers, B.

    The aim of this project was to determine if it is possible to stimulate suckling in piglets kept with their mother to suck by exposing them to a recorded grunting of a sow, and if so, to study if they act normally when their own mother is grunting. Finally, we wanted to find out how the piglets...

  7. A note on the effects of calf stimuli on the response of Zebu cows to Synchro-mate-B

    Contributor(s):: Quesada, Y., Estrada, S., Cubero, M., Garcia, F., Galina, C. S., Molina, R., Orihuela, A.

    The effect of Synchro-mate-B (SMB, ear implant containing 6 mg norgestomet) was measured on the oestrous response and the establishment of cyclicity using different calf stimuli. Multiparous Zebu cows, were divided in three groups. In the first, 32 animals were treated with SMB leaving the calves...

  8. A novel environment inhibits milk ejection in the pig but not through HPA activity

    Contributor(s):: Rushen, J., Ladewig, J., Passille, A. M. B. de

    Six sows (3-14 days postpartum) were placed with their piglets in a different farrowing pen (novel environment) for 2 h or were driven into the new pen then immediately returned to their own pen (control). All sows were subject to both treatments over 2 consecutive days. Nursings were recorded as...

  9. A review of the problem of milk-sucking in dairy cows

    Contributor(s):: Grommers, F. J.

  10. A simple method for fostering lambs using anoestrous ewes with artificially induced lactation and maternal behaviour

    Contributor(s):: Kendrick, K. M., Costa, A. P. da, Hinton, M. R., Keverne, E. B.

    The possibility of a simple method for using anoestrous ewes to foster orphan or triplet lambs was investigated. 22 anoestrous ewes (12 multiparous and 20 multiparous) were given vaginal sponges containing medroxyprogesterone acetate (250 mg) and oestradiol dipropionate (ODP) (25 mg) for 2 wk....

  11. A study of the development of the teat order in piglets

    Contributor(s):: Hemsworth, P. H., Winfield, C. G., Mullaney, P. D.

    The suckling and fighting behaviour of 3 litters of piglets was observed from birth to 4 h of age. Although each piglet suckled from an average of 7 teats during this early period, each piglet spent an average of 55% of its suckling time at a single teat. The development of the teat order was...

  12. A test of sows' willingness to nurse

    Contributor(s):: Thodberg, K., Jensen, K. H.

    The aim of the study was to validate a test for willingness of sows to nurse to find a test situation in which maximum variation in the nursing motivation of sows was displayed. The factors considered were the interval since last successful nursing, level of hunger of the sow and activity of the...

  13. Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective

    Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.

    Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...

  14. Allosuckling allows growing offspring to compensate for insufficient maternal milk in farmed guanacos ( Lama guanicoe )

    | Contributor(s):: Zapata, B., Correa, L., Soto-Gamboa, M., Latorre, E., Gonzalez, B. A., Ebensperger, L. A.

    While allonursing, the provision of milk to non-offspring by females, involves a potential cost to their own offspring, allosuckling, the suckling from females other than their own mother may allow offspring to compensate for previous deficiencies in maternal milk. We tested this hypothesis in...

  15. Allosuckling in cattle: gain or compensation?

    | Contributor(s):: Vichova, J., Bartos, L.

    The objective of this study was to assess the impact of allosuckling on the growth of calves in a herd of domestic cattle. We determined (i) if allosucking calves achieved a better weight gain than non-allosucking calves ingesting milk surplus to maternal milk supply or if they were compensating...

  16. Allosuckling in domestic pigs: teat acquisition strategy and consequences

    | Contributor(s):: Illmann, G., Pokorna, Z., Spinka, M.

    The aims of the study were to identify the strategies used by allosucklers and teat losers during teat acquisition; to assess how teat fidelity was affected by allosuckling and how allosuckling affected weight gain of the allosuckler and teat loser. Ten pairs of sows and their litters were used...

  17. An artificial sow to investigate the behaviour of sucking piglets

    | Contributor(s):: Jeppesen, L. E.

    A dummy sow and feeding system was developed to rear piglets from 24 h of age to at least 3 wk. The dummy sow incorporated particular features associated with the real sow which appeared to stimulate the development of normal feeding behaviour in the form of nuzzling and sucking. Good growth...

  18. An ethogram of piglet vocalizations during suckling

    | Contributor(s):: Jensen, P., Algers, B.

  19. An exploratory study on the effects of a straw dispenser in farrowing crates

    | Contributor(s):: Bulens, A., Renders, L., Beirendonck, S. van, Thielen, J. van, Driessen, B.

    The effect of a straw dispenser in farrowing crates was investigated to determine the extent to which the provision of small quantities of straw has an influence on both sows and piglets. Sows and suckling piglets are often housed in barren environments with limited opportunities to show behavior...

  20. Analysing qualitative behavioural data: a Markov chain aid

    | Contributor(s):: Hines, W. G. S., Hurnik, J. F., Mullen, K.

    Redundancy of information present in successive observations of animal behaviour can be tested for, and its effects studied, with a statistical procedure, Markov chain analysis. Efficient sampling frequency and the precision of estimators are both found to be affected by the redundancy present in...
