Shrinking membership in the American Society of Animal Science: does the discipline of poultry science give us some clues?

Concerns have been expressed by the American Society of Animal Science (ASAS) leadership about the declining membership in ASAS. I present the viewpoint that the history of the Poultry Science Association (PSA) membership and the elimination of poultry science departments from many land grant universities could be an indication of what the future holds for animal science. I suggest that the industrialization of poultry production has led to a decline in the demand for traditionally trained poultry scientists. Industrialization of swine production is proceeding rapidly, with other animal-based industries showing the same trend. If maintaining a large ASAS membership is indeed a priority, new opportunities must be developed. Equine and companion animal programs offer such possibilities, tapping into a high level of student interest.     

What does the new century offer range science in southern Africa?

Range Science, as a developing discipline in southern Africa, is reviewed over its 60 years of formal existence. The context of the African political and socia-economic environment is used as a background to examine the impact that range science has made on the agricultural and conservation arenas. The relations between organised agriculture, government, conservation agencies and the non-formal sector regarding the development of the discipline are reviewed. The role of professional societies, such as the Grassland Society of Southern Africa and the Zimbabwe Grassland Society, are seen as key to the future development of the discipline and a sustainable land-use, involving the region's rangelands, in both the resource-poor and well-resourced sectors. The need to adapt to the dynamic political and economic environment as well as the changing human- and financial-resource allocations by government is debated.

As a consequence of globalisation and improving international trade, a more environmentally conscious legislation is developing. Range Science can playa key role in the rehabilitation of areas exploited for their mineral resources. This for example requires the development of a partnership between the discipline and industry to ensure that the training of scientists equips them with the skills to operate out of the their traditional home of servicing commercial agriculture. To this must be added the re-tooling of current professionals to adapt to their new role in servicing resource-poor farmers and communal landowners. This, in turn, impacts upon the tertiary education sector and its curricula.

Strategies for making a positive and constructive contribution to the development of the regions rangeland resources and the discipline are presented.     

What's in a name? Inflammatory airway disease in racehorses in training

The term 'inflammatory airway disease' (IAD) is often used to describe the syndrome of lower airway inflammation that frequently affects young racehorses in training around the world. In practice, this inflammation is generally diagnosed using a combination of endoscopic tracheal examination, including grading of amounts of mucus present and tracheal wash sampling. However, a recent consensus statement from the American College of Veterinary Internal Medicine concluded that bronchoalveolar lavage (BAL) sampling, rather than tracheal wash (TW) sampling, is required for cytological diagnosis of IAD and that tracheal mucus is not an essential criterion. However, as BAL is a relatively invasive procedure that is not commonly used on racing yards, this definition can only be applied routinely to a biased referral population. In contrast, many practitioners continue to diagnose IAD using endoscopic tracheal examination and sampling. We argue that, rather than restricting the use of the term IAD to phenotypes diagnosed by BAL, it is important to distinguish in the literature between airway inflammation diagnosed by BAL and that identified in the field using TW sampling. We suggest the use of the term brIAD for the former and trIAD for the latter. It is essential that we continue to endeavour to improve our understanding of the aetiology, pathogenesis and clinical relevance of airway inflammation identified in racehorses in training using tracheal examination and sampling. Future studies should focus on investigations of the component signs of airway inflammation.     

ImproWin? in the treatment of gastric ulceration of the squamous mucosa in trotting racehorses

Background

Gastric ulceration is highly prevalent in horses, and there is a large commercial market for feed-additives and non-licenced products that claim effect for prevention and treatment of gastric ulceration. ImproWin® has been used as a feed additive in horses with anecdotal evidence that it may have some positive effects on gastric ulceration.The aim of this study was to investigate the effect of ImproWin® treatment on spontaneously occurring gastric ulcers of the squamous mucosa in Standardbred and Coldblooded trotting racehorses.The study was performed as a randomised, double-blinded, single centre study with stratified semi cross-over design with breed as stratification factors. The horses were clinically and endoscopically examined prior to start and after three weeks of treatment. The ulcerations were scored in accordance with Equine Gastric Ulcer Council (EGUC) recommendations on a 5 point scale and on a 10 cm Visual Analogue Scale (VAS). The patients were responder-classified after 3 weeks. Responders in need of ulcer treatment were randomly allocated to 2 or 4 weeks of additional treatment. Non-responders to placebo were crossed to ImproWin®.

Results

The 5-point EGUC score and VAS recorded score was significantly reduced (P ≤ 0.01) in both groups after 3 weeks of treatment. From 3 weeks to the end of treatment the score was further significantly reduced in the ImproWin® group (P ≤ 0.05).At the end of treatment, 78% in the ImproWin® group and 54.8% in the placebo group were classified as responders. The difference was significant (P = 0.04).

Conclusions

ImproWin® may aid the healing process of ulcers of the gastric squamous mucosa of trotters.     

Can science save the giant panda (Ailuropoda melanoleuca)? Unifying science and policy in an adaptive management paradigm

The giant panda (Ailuropoda melanoleuca David, 1869) is an iconic species for global conservation, yet field research has only recently advanced to the point where adaptive management is possible. Here, we review recent developments in giant panda conservation science and propose a strategic plan for moving panda conservation forward. Because of scientific, funding, political, and logistical hurdles, few endangered species management programs have embraced adaptive management, wherein management decisions are shaped iteratively by targeted scientific research. Specific threats, such as habitat destruction, anthropogenic disturbance and fragmented nonviable populations, need to be addressed simultaneously by researchers, managers and policy‐makers working in concert to understand and overcome these obstacles to species recovery. With the backing of the Chinese Government and the conservation community, the giant panda can become a high‐profile test species for this much touted, but rarely implemented, approach to conservation management.     

What kind of formation in the multiethnic culture of the European Union of the third millennium?

Even though occidental food production and control systems guarantee a reasonable level of safety for consumers, western countries are facing a growing phenomenon of immigration from all over the world. With this enrichment and the shuffling of cultures and customs in the same places, even alimentary habits undergo an unavoidable evolution, also influencing the commercial trends of society. The growing demand for ethnic products, often of uncertain provenance, composition and manufacturing, has motivated the appearance of illegal trade and markets or improper local productions besides the legal ones, implying a rise in hygienic risks for the consumers. These underground realities, together with the unfilled gap that still exists between different cultures and customs cause significant difficulties in carrying out efficient controls to guarantee sanitary safety for consumers. For this reason, the risks associated with this increasing globalization must be faced with proper information and a decisive formative strategy must be divided, in order to allow the operator of the whole system and control employees to be acquainted about different raw materials, manufacturing systems, alimentary habits, languages for communication and commercial dynamics which stand beyond the new alimentary trends.     

The human being from the point of view of animals or, Who knows whether the breath of men goes upwards? (Ecclesiastes 3:21)]

The question of whether animals have souls has been asked since as early as the Old Testament. Where this is believed to be true, fiction has provided interesting models in literature: The human being as seen by animals has been a popular subject since Apuleius' 'Asinus aureus' and how man appears from the perspective of a donkey or a beetle, that is to say the perspective from below, becomes controversial. Examples may be found in all languages and centuries in Jonathan Swift, Miguel Cervantes, E. T. A. Hoffmann, Ludwig Tieck, Heinrich Heine, Viktor von Scheffel, Franz Kafka and others. Résumé at the end: How does man answer this question or his own self-questioning?     

Modernizing the animal science curriculum: is change needed?

To identify an animal science curriculum is difficult because it is a "moving target" due to changing needs and demands of our society and, more specifically, to changes in the backgrounds and interests of students. Therefore, animal science curriculums not only should change, but must change, if they are to succeed. With new technological innovations and discoveries that either modify, supplement, or change basic concepts and approaches, it is paramount that changes in courses as well as in the curriculum conform. Because of the applied nature of animal science and because of the many unknowns yet to be discovered, the curriculum should be under continual scrutiny. However, we must not fix something when it is not broken. For all practical purposes, a curriculum reflects a philosophy of what subjects should be included to complete a plan of study. After a philosophy has been established the base curriculum will seldom change significantly. When it does, it will be the result of a change in people's philosophies rather than a reflection of industry needs or student interests. Teachers should not forget how to teach most effectively the material and must never lose sight of their goal of molding students into knowledgeable, wise, and responsible citizens in our society.(ABSTRACT TRUNCATED AT 250 WORDS)     

Does the Microbial Flora in the Ejaculate Affect the Freezeability of Stallion Sperm?

In an attempt to evaluate the possible relationship between the microbial flora in the stallion ejaculate and its ability to freeze, three ejaculates from five stallions were frozen using a standard protocol. Before freezing, an aliquot was removed for bacteriological analysis. Bacterial growth was observed in all the ejaculates studied. The isolated microorganisms were: Staphylococcus spp. and Micrococcus spp. (in all the stallions), β-haemolytic Streptococcus (in stallions 3 and 4), Corynebacterium spp. (in stallions 1, 3–5), Rhodococcus spp. (in stallion number 2), Pseudomonas spp. (in stallion number 1) and Klebsiella spp. (in stallions 1, 3 and 5). The presence and richness of Klebsiella and β-haemolytic Streptococcus in the ejaculate were related to two sperm variables post-thaw, namely the proportion of dead spermatozoa (ethidium+ cells; r = 0.55, p < 0.05) and the amplitude of lateral displacement of the sperm head (ALH, μm; r = −0.56, p < 0.05), respectively. The degree of growth of Corynebacterium spp. in the ejaculate was positively correlated with the percentage of spermatozoa showing high caspase activity post-thaw (r = 0.62, p < 0.05). The presence and number of colonies of β-haemolytic Streptococcus were negatively correlated (r = −0.55, p < 0.05) with low sperm caspase activity. It is concluded that the microbial flora of the equine ejaculate may be responsible for some of the sublethal damage experimented by the spermatozoa during cryopreservation.

Current status of medical and veterinary entomology in France: endangered discipline or promising science?

Following alarming statements (French Senate, Académie des Sciences) on the present situation concerning entomology and systematics in France, the Conseil Général Vétérinaire designated one of us (D.C.) to carry out a survey on the status of medical and veterinary entomology (MVE) with respect to research orientations and university curricula. Around 100 participants, including scientists, teachers and several directors of research and educational bodies, were interviewed and filled in questionnaires for this survey. On the basis of the results, it was concluded that the deterioration of MVE in France is associated with: (1) the hasty reorganisation of training and research in the life sciences, leading to the disappearance of several disciplines. Hence, the postgraduate DEA degree in entomology was eliminated, and even the name 'entomology' no longer appears in teaching programmes or on research contracts; (2) France's withdrawal from action research programmes in developing countries. Although these programmes were efficient in controlling outbreaks of major endemic diseases, integrated pest and vector management programmes have been replaced by basic health care ('Health for everyone in 2000') and vaccination programmes; (3) the general shift from field to laboratory research, focused mainly on molecular mechanisms. The survey results confirmed generally acknowledged trends concerning many points and highlighted several specific problems, such as the disappearance of systematics experts. Several potential solutions are proposed.
