  1. Some aspects of milk that elicit non-nutritive sucking in the calf

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

    Male Holstein dairy calves were allowed to suck a non-nutritive teat after meals of either cow milk or milk replacer, and the amount of non-nutritive sucking that occurred during the 10 min following the meal was observed. There were no differences between milk and commercial milk replacer in the...

  2. Sucking motivation and related problems in calves. (Special issue: Suckling)

    Contributor(s):: Passille, A. M. de

    Because the survival of young mammals depends on sucking success, it is assumed that sucking motivation must be strong and that sucking deprivation would result in frustration, which could have a negative impact on the animals' welfare. This concern, as well as that regarding cross-sucking...

  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. The effect of a gradual separation from the mother on later behavioral, immune and endocrine alterations in artificially reared lambs

    Contributor(s):: Sevi, A., Caroprese, M., Annicchiarico, G., Albenzio, M., Taibi, L., Muscio, A.

    The aim of the experiment was to compare the welfare and weight gains of artificially reared lambs when gradually separated from their mothers or separated from them early and immediately or gradually moved from maternal to reconstituted milk. Forty Comisana lambs were assigned to a control...

  5. The effects of conditioning to suckling, milking and of calf presence on the release of oxytocin in dairy cows. (Special issue: Suckling)

    Contributor(s):: Tancin, V., Kraetzl, W. D., Schams, D., Bruckmaier, R. M.

    The aim of this study was to record oxytocin (OT) release during milking (M) in the presence or absence of a calf, suckling (S) and calf removal just before the next milking in cows during postpartum or early lactation periods. Furthermore, the release of OT was examined during S and M in unknown...

  6. The relationship between attitudes, personal characteristics and behaviour of stockpeople and subsequent behaviour and production of dairy cows

    Contributor(s):: Waiblinger, S., Menke, C., Coleman, G.

    The relationships amongst attitudes and personal characteristics of stockpeople, their interactions with cows, the behaviour of cows during milking towards humans and average milk yield were investigated on 30 small, family-run dairy farms where cows were housed in a cubicle shed. Several...

  7. An evaluation of mattresses and mats in two dairy units

    Contributor(s):: Chaplin, S. J., Tierney, G., Stockwell, C., Logue, D. N., Kelly, M.

    In order to investigate the relative merits of mats and mattresses in terms of cow comfort, production and performance, 29 cows were housed on ethylethene vinyl acetate mats and 29 on mattresses of loose rubber crumb with a polypropylene cover, at each of 2 similar dairy units of the Scottish...

  8. Avoidance-related behavioural variables and their relationship to milk yield in pasture-based dairy cows

    Contributor(s):: Dodzi, M. S., Muchenje, V.

    The behavioural responses of Jersey, Friesland and crossbred cows to humans were determined by recording their avoidance distance scores (AD), exit speed (ES), pen score (PS), pen behaviour score (PBS), platform score (PLS), and the occurrence of kicking (KCK) and stepping (SPG) during milking in...

  9. Behaviour of Zebu and crossbred cows in restricted suckling groups. (Special issue: Suckling)

    Contributor(s):: Das, S. M., Redbo, I., Wiktorsson, H.

    The aim of this study was to investigate whether Zebu (Bos indicus) and crossbred (Bos indicus x Bos taurus) cows differ in maternal related behaviour during restricted group suckling. The behaviours of 20 Zebu and 16 crossbred cows were recorded during two 30-min sessions each day after milking...

  10. Behavioural response to humans and the productivity of commercial dairy cows

    Contributor(s):: Breuer, K., Hemsworth, P. H., Barnett, J. L., Matthews, L. R., Coleman, G. J.

    This study examined the relationships between the attitude and the behaviour of the stock-person towards cows and the behavioural response to humans and the milk yield of cows at 31 commercial dairy farms over 1 lactation. The attitude of the stock-person was measured on the basis of the...

  11. Breed and maternal effects on the intake of tannin-rich browse by juvenile domestic goats ( Capra hircus )

    Contributor(s):: Glasser, T. A., Ungar, E. D., Landau, S. Y., Perevolotsky, A., Muklada, H., Walker, J. W.

    Goat breeds differ in their consumption of tannin-rich browse, but the relative contributions of genetics and learning to these differences is unclear. The objective of this study was to differentiate between the effects of breed (nature) and rearing environment (nurture) on consumption of a...

  12. Clustered environmental enrichments induce more aggression and stereotypic behaviour than do dispersed enrichments in female mice

    Contributor(s):: Akre, A. K., Bakken, M., Hovland, A. L., Palme, R., Mason, G.

    Adding environmental enrichments to a previously resource-poor cage or enclosure can sometimes cause elevated aggression in socially housed animals, due to competition over the provided resources. Here, using female C57BL/6J mice, we investigated whether the way that environmental enrichments are...

  13. Diurnal distribution of dairy cow defecation and urination

    Contributor(s):: Aland, A., Lidfors, L., Ekesbo, I.

    This study investigated the diurnal distribution of urination and defaecation in tied dairy cows with reference to management routines and milk yield/feeding intensity. A total of 16 lactating cows and 4 heifers were videotaped during 9 consecutive 24-h periods. The cows had a mean of 16.1...

  14. Effect of a supplement rich in linolenic acid, added to the diet of gestating and lactating goats, on the sensitivity to stress and learning ability of their offspring

    Contributor(s):: Duvaux-Ponter, C., Rigalma, K., Roussel-Huchette, S., Schawlb, Y., Ponter, A. A.

    The requirements for polyunsaturated fatty acids during brain development are high and in certain situations supply may be inadequate. Numerous studies in rodents have shown that a diet rich in linolenic acid improves learning ability and modifies emotional reactivity of offspring. Thirty-two...

  15. Effect of different free stall surfaces on behavioural, productive and metabolic parameters in dairy cows

    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...

  16. Milk feeding systems for dairy calves in groups: effects on feed intake, growth and health. (Special Issue: Behaviour and welfare of cattle)

    Contributor(s):: Hepola, H.

    The number of calves reared in groups is increasing. If the calves are reared in small groups, they can be fed from buckets with or without teats or from small containers connected with teats via tubes. In big groups the simplest solution is ad libitum feeding from the containers with teats or...

  17. Performance and feeding behaviour of calves on ad libitum milk from artificial teats

    Contributor(s):: Appleby, M. C., Weary, D. M., Chua, B.

    Weight gain, milk intake, starter intake and number of days with diarrhoea were measured for individually housed Holstein calves offered milk twice daily by bucket at 5% of body weight per feeding (n=11) or ad libitum from a teat (n=12) from birth until 4 weeks of age. Mean weight gains during...

  18. 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...

  19. Predictability of nursings without milk ejection in domestic pigs

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

    Seven to 8 days after farrowing the suckling behaviour of 7 sows and their piglets (n = 8-10 per sow) was recorded for 24 h. Piglets were separated from the sows and were released into the sow's pen every 35 min to allow them to suckle. Teat massaging movements and sows' grunts were counted...

  20. Preference of dairy cows: indoor cubicle housing with access to a total mixed ration vs. access to pasture

    Contributor(s):: Charlton, G. L., Rutter, S. M., East, M., Sinclair, L. A.

    Cattle are grazing animals so it is generally assumed that pasture is a welfare friendly system as it is natural and allows the expression of normal behaviour, which may be restricted indoors. However, high yielding dairy cows may not be able to fulfil their nutritional demands from grass alone...
