  1. Effect of cage type on fecal corticosterone concentration in buck rabbits during the reproductive cycle

    Contributor(s):: Cornale, P., Macchi, E., Renna, M., Prola, L., Perona, G., Mimosi, A.

    Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type and...

  2. How to train a dog to detect cows in heat-training and success

    Contributor(s):: Johnen, D., Heuwieser, W., Fischer-Tenhagen, C.

    Efficient and accurate estrus detection is a key management factor determining acceptable reproductive performance in dairy herds. Previous studies have shown that dogs can differentiate between vaginal mucus samples of cows in estrus and vaginal mucus samples of cows in diestrus with an accuracy...

  3. Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing

    Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.

    Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...

  4. Assessment: effects of porcine zona pellucida immunocontraception on oestrous cyclicity in feral horses

    Contributor(s):: Powell, D. M., Monfort, S. L.

    The following study used noninvasive faecal hormone monitoring to assess whether contraception with porcine zona pellucida (PZP) had an impact on oestrous cycle characteristics in a herd of feral horses living on Assateague Island, Maryland. The study assayed longitudinal faecal samples,...

  5. Effect of breed, cage type, and reproductive phase on fecal corticosterone levels in doe rabbits

    Contributor(s):: Prola, L., Cornale, P., Renna, M., Macchi, E., Perona, G., Mimosi, A.

    Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of...

  6. Using fecal hormonal and behavioral analyses to evaluate the introduction of two sable antelope at Lincoln Park Zoo

    Contributor(s):: Loeding, E., Thomas, J., Bernier, D., Santymire, R.

    Introductions of sable antelope (Hippotragus niger) can be difficult due to the potential ensuing aggression compounded by their large horns. The goal was to use hormonal assays and behavioral analyses to evaluate the success of an introduction of 2 adult females at Lincoln Park Zoo. The...

  7. The welfare implications of large litter size in the domestic pig II: management factors

    Contributor(s):: Baxter, E. M., Rutherford, K. M. D., D'Eath, R. B., Arnott, G., Turner, S. P., Sandoe, P., Moustsen, V. A., Thorup, F., Edwards, S. A., Lawrence, A. B.

  8. Repeated locomotion scoring of a sow herd to measure lameness: consistency over time, the effect of sow characteristics and inter-observer reliability

    Contributor(s):: D'Eath, R. B.

  9. Continuous presence of rams hastens the onset of estrus in ewes synchronized during the breeding season

    Contributor(s):: Romano, J. E., Christians, C. J., Crabo, B. G.

    90 pluriparous ewes (30 Whiteface Western, 30 Suffolk and 30 Hampshire Down) from the St. Paul Sheep Teaching and Research Unit of the University of Minnesota (USA) were divided by breed and oestrous was synchronized with intravaginal sponges. These sponges were impregnated with...

  10. Does in proestrus-estrus hasten estrus onset in does estrous synchronized during breeding season

    Contributor(s):: Romano, J. E.

    During the breeding season, 68 Nubian goats were synchronized for oestrus with intravaginal sponges impregnated with fluorgestone acetate (FGA, Chronogest, 30 mg; n=36) or medroxyprogesterone acetate (MAP, Sincrocel, 60 mg; n=32). The experiment was performed in two replicates. In each replicate,...

  11. Preliminary study of the development of the Flehmen response in Equus caballus

    Contributor(s):: Weeks, J. W., Crowell-Davis, S. L., Heusner, G.

    The flehmen response is commonly seen in most ungulates as well as in several other species (e.g. felids). The behaviour is most often thought to be part of the sexual behavioural repertoire of males. One reigning hypothesis suggests that this behaviour allows the male to determine the oestrous...

  12. The temporal estrous patterns of female alpine musk deer in captivity

    Contributor(s):: Meng, XiuXiang, Yang, QiSen, Xia, Lin, Feng, ZuoJian, Jiang, YingWen, Wang, PeiMing

    From 1996 to 2000, we collected data about rutting habits of captive Alpine musk deer (Moschus sifanicus) in the Breeding Center of Alpine Musk Deer (BCAMD) located in the Xinglongshan National Nature Reserve of China. We examined the temporal rutting patterns to determine the timing and...

  13. Consequences of different suckling systems for reproductive activity and productivity of cattle in tropical conditions. (Special issue: Suckling)

    Contributor(s):: Galina, C. S., Rubio, I., Basurto, H., Orihuela, A.

    The late onset of ovarian activity in mature cattle raised under tropical conditions is the major setback impeding sound reproductive performance needed to meet the increasing demand for livestock products in the area. The effect of suckling has been cited as one of the most important factors...

  14. Deprivation of straw bedding alters PGF<sub>2 alpha </sub>-induced nesting behaviour in female pigs

    Contributor(s):: Burne, T. H. J., Murfitt, P. J. E., Gilbert, C. L.

    Sows are highly motivated to build a maternal nest on the day preceding parturition. A model for nest building has been established in pigs, in which exogenously administered prostaglandin F2 alpha (PGF2 alpha ) may be used to elicit nesting behaviour in cyclic, pseudopregnant and pregnant pigs....

  15. Estrous synchrony in a group of African elephants (Loxodonta africana) under human care

    Contributor(s):: Weissenbock, N. M., Schwammer, H. M., Ruf, T.

  16. A quantitative study of pre-ovulatory behaviour in cattle (British Friesian heifers)

    Contributor(s):: Esslemont, R. J., Glencross, R. G., Bryant, M. J., Pope, G. S.

    24 British Friesian heifers with normal oestrous cycles were observed continuously for 24 days. The exhibition of 13 components of behaviour was recorded. The 11 most frequently seen components which involved the participation of 2 heifers were classified as aggressive (butting), investigatory...

  17. A review of historically significant publications from German speaking countries concerning the behaviour of domestic farm animals

    Contributor(s):: Sambraus, H. H.

    German language publications up to and including 1958 which concerned the behaviour of domestic farm animals are reviewed. The subjects covered include behaviour of cows on different grazing systems, and eating habits in cattle.

  18. Preliminary observations on the urinary behaviour of female Jack Russell Terriers in relation to stage of the oestrous cycle, location, and age

    Contributor(s):: Wirant, S. C., Halvorsen, K. T., McGuire, B.

    In female canids, including domestic dogs (Canis familiaris), scent-marking with urine is thought to convey information on reproductive state, yet little is known about how urinary behaviour changes across specific stages of the oestrous cycle. We measured urinary behaviour (proportion of...

  19. Intrauterine position effects in female swine: subsequent reproductive performance, and social and sexual behavior

    Contributor(s):: Parfet, K. A. P., Ganjam, V. K., Lamberson, W. R., Rieke, A. R., Saal, F. S. vom, Day, B. N.

    The sex of adjacent fetuses has been shown to affect the subsequent behaviour and reproductive performance of rodents. In the present study, sows were slaughtered at day 112 of gestation, and piglets were delivered manually. The piglets' uterine position was recorded as between 2 [female][female]...

  20. Sexual preference of mares ( Equus caballus ) for individual stallions

    Contributor(s):: Pickerel, T. M., Crowell-Davies, S. L., Caudle, A. B., Estep, D. Q.

    Eight mares were tested to determine if they remained near 1 of 2 stallions longer than would be expected if association was random. Six stallions were paired in 30 combinations and each mare was tested 30 times. The mares demonstrated a definite preference for individual stallions throughout the...
