  4. The ticking clock: addressing farm animal welfare in emerging countries

    Contributor(s):: Keyserlingk, M. A. G. von, Hotzel, M. J.

    Over the last decade many emerging economies, and in particular Brazil, have established themselves as major players in global food animal production. Within these countries much of the increase in food animal production has been achieved by the adoption of intensive housing systems similar to...

  5. Demographics of the owned dog population in Miacatlan, Mor. Mexico

    Contributor(s):: Orihuela, T. A., Solano, V. J.

    Information was collected on 1026 dogs in 575 households during 1993. The ratio of persons per dog was 2.63. 85% of the households had at least 1 dog. Most of the animals were intact (92.22%), adult (38.2%), mongrels (61.85%) and kept as guards (65%). Dogs were primarily received as gifts...

  6. Benefits of dog ownership: comparative study of equivalent samples

    Contributor(s):: Gonzalez Ramirez, M. T., Landero Hernandez, R.

    Owing to the inconclusive findings of research regarding the health benefits of pet ownership, we compared perceived health, stress, life satisfaction, happiness, and psychosomatic symptoms in dog owners and non-dog owners. As an attempt to overcome some earlier methodological issues, the sample...

  7. Impact of a bilingual mobile spay/neuter clinic in a U.S./Mexico border city

    Contributor(s):: Poss, J. E., Everett, M.

    There are between 4 and 10 million dogs and cats killed annually in the United States. Although there are no accurate national estimates of the number of companion animals who are sterilized surgically. Approximately 26,000 companion animals are euthanized annually in El Paso County, Texas,...

  8. Human-dog interactions and behavioural responses of village dogs in coastal villages in Michoacan, Mexico

    Contributor(s):: Ruiz-Izaguirre, E., Eilers, K. H. A. M., Bokkers, E. A. M., Ortolani, A., Ortega-Pacheco, A., Boer, I. J. M. de

    In Mexican villages, most households keep dogs that roam freely. Therefore, socialisation of village dogs occurs in a different context than that of companion dogs in developed countries. The objectives of this study were: (1) to assess village dogs' behavioural responses towards familiar and...

  9. Psychometric properties of the Lexington Attachment to Pets Scale: Mexican version (LAPS-M)

    Contributor(s):: Gonzalez Ramirez, M. T., Quezada Berumen, L. del C., Landero Hernandez, R.

    The Lexington Attachment to Pets Scale (LAPS) is perhaps the most widely used instrument to assess human emotional attachments to pets and is suitable for both dog and cat owners. However, this instrument has not been translated into Spanish. Thus, the present study aimed to assess the...

  10. Perceptions of village dogs by villagers and tourists in the coastal region of rural Oaxaca, Mexico

    Contributor(s):: Ruiz-Izaguirre, E., Eilers, C. H. A. M.

  11. Salivary cortisol in captive dolphins (Tursiops truncatus): a non-invasive technique

  12. Science and the consequences of mistruct: lessons from recent GM controversies. (Special issue: Ethics as a dimension of agrifood policy: selected papers from the 4th Congress of the European Society for Agricultural and Food Ethics)

    Contributor(s):: Scott, D.

    In 2001, it was announced that transgenic DNA had introgressed into traditional strains of maize in Mexico. A controversy 'erupted and raged' throughout 2001 and 2002. This episode represents an acute breakdown in scientific discourse. The following inquiry looks into the causes of this...

  13. Episodic-like memory in crossbred Yucatan minipigs ( Sus scrofa )

    Contributor(s):: Kouwenberg, A. L., Walsh, C. J., Morgan, B. E., Martin, G. M.

    Episodic-like memory, involving simultaneous recall of what, where and when aspects of a past event, has been demonstrated in some non-human species and is hippocampal-dependent. Our study explored episodic-like memory in pigs, a previously un-studied species that has shown evidence of highly...

  14. Grazing and browsing times of goats with three levels of herbage allowance

    Contributor(s):: Orihuela, A., Solano, J. J.

    Three adjacent mixed irrigated pastures of grass (Cenchrus ciliaris) and shrub (Leucaena leucocephala) were used. Grass height was maintained at 27, 14 and 7 cm for treatments I, II and III, respectively, while the height of bushes (6666 plants/ha) were all kept at 150 cm. DM availability was...

  15. Mating behavior of bucks and does in goat operations under range conditions

    Contributor(s):: Mellado, M., Cardenas, C., Ruiz, F.

    The objectives of this study were to characterize the mating capacity of bucks under range condition and assess the effect of mating frequency on flock fertility. Two adjacent flocks of crossbred goats (Criollo x dairy goat breeds; n = 70 does, 5 bucks and 141 does, 4 bucks) were used. The mating...

  16. Social order measured in pasture and pen conditions and its relationship to sexual behavior in Brahman ( Bos indicus ) cows

    Contributor(s):: Orihuela, A., Galina, C. S.

    The social order of 20 non-lactating, non-pregnant Brahman cows (2-6 years old) was determined by recording content and outcome of all agonistic interactions. The herd was observed at pasture for 1.5 h and in a yard for 2 h per day. This routine was undertaken every other day from 06.00 to 18.00...

  17. A note on the behavior of feral cattle in the Chihuahuan Desert of Mexico

    Contributor(s):: Hernandez, L., Barral, H., Halffter, G., Colon, S. S.

    Habitat use and behaviour of three feral cows were compared to three domestic cows in the Mapimi Biosphere Reserve, Chihuahuan Desert, where approximately 1000 feral cows were found on 151 000 ha. Feral cattle were found to represent an ecotype adapted to desert conditions. In comparison with...

  18. 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...
