In Chile, cow carcasses present the highest bruise prevalence compared with other cattle categories; however, the causes of the bruises are frequently unknown. In this study, 52 cull cows were transported to the slaughterhouse in three batches under identical transport conditions. A combination of direct observation and video analyses was used to determine moment, pre-slaughter stage and cause ...
This paper aims to contribute to the development of a cost-effective alternative to expensive on-farm animal-based welfare assessment systems. The objective of the study was to design an animal welfare index based on central database information (DBWI), and to validate it against an animal welfare index based on-farm animal-based measurements (AWI). Data on 63 Danish sow herds with herd-sizes o...
This paper summarizes the major advances in farm animal assisted reproduction in the last 20 years with particular attention to the contributions of the authors. A main emphasis is on the biology of the oocyte, including a description of methods for isolation of developing follicles and culture of the corresponding oocytes. Milestones that have led to optimization of procedures for maturation o...
All farm animals will experience some level of stress during their lives. Stress reduces the fitness of an animal, which can be expressed through failure to achieve production performance standards, or through disease and death. Stress in farm animals can also have detrimental effects on the quality of food products. However, although a common assumption of a potential effect of stress on food ...
Antibiotics and antibiotic resistance made news on several fronts in the past year. Many public health organizations, including the CDC, used terms such as "crisis", "catastrophic consequences", and "nightmare scenario" to highlight the rapid emergence and spread of antibiotic resistance. A report from the Pew Commission on Industrial Farm Animal Production, on the fifth anniversary of the publ...
This paper summarises the current status of comparative mapping in farm animals. For most of the major farm animal species, a wide range of genomic tools are now available to create high-resolution genetic and physical maps of the genome. For many farm animals, the use of radiation hybrid panels and sequence data from expressed sequence tag (EST) projects has accelerated the development of high...
To evaluate the current status of farm animal behavioral research in North America, we searched and analyzed the scientific literature, consulted the national Agricultural Library and the Current Research Information System of the USDA and sought advice from several authorities. We than sent letters to 78 North American behavioral researchers, inviting them to supply information about their cur...
Introduction The need to conserve farm animal biodiversity is accepted by many countries through the ratification of the Convention of Biological Diversity (CBD, 1992). Although farm animal breeds are not well defined in general terms, they are the typical unit for conservation. Based on an inventory of the actual breeds (on the global scale this is done by FAO through the world watch list, Sch...
Draft animal power (DAP) has been identified as an environmentally friendly technology that is based on renewable energy and encompasses integration of livestock and crop production systems. Draft animal technology provides farmers with a possibility to cheaply access and use manure from the draft animals and farm power needed to apply renewable practices for land intensification. Compared to m...
Animal-assisted therapy (AAT) with farm animals for humans with psychiatric disorders may reduce depression and state anxiety, and increase self-efficacy, in many participants. Social support by the farmer appears to be important. Positive effects are best documented for persons with affective disorders or clinical depression. Effects may sometimes take a long time to be detectable, but may occ...
