(1996) who found no differences between feeding levels in terms of fertility traits in cows. But negative energy balance and metabolic stress are significantly related to a lower pregnancy rate (Bertoni et al., 2009). Generally, there is very little literature on the relationship of concentrate feeding and animal health. Milk yield and milk protein content in the first 100 days of lactation decreased slightly. Broderick (2003) observed an increasing milk yield and milk protein concentration if dairy cows are fed with higher amounts of dietary energy. The risk of rumen acidosis (FPR< 1.1) was diminished when concentrate feeding was restricted or given up. Bramley et al. (2008) described that dairy cows fed with highly fermentable carbohydrates showed a high milk yield but also a very low FPR and rumen pH. Suggestions to tackle the future challenges of organic animal husbandry One of the challenges of future organic farming will be the site and animal adapted production without concurrence to human alimentation. Furthermore the use of antibiotics and other synthetic drugs should be reduced in organic farming with holistic animal health concepts including prevention on herd level and the use of complementary medicine.

Abstract RAHMANN G & GODINHO D (Ed.) (2012): Tackling the Future Challenges of Organic Animal Husbandry. Proceedings of the 2 nd OAHC, Hamburg/Trenthorst, Germany, Sep 12-14, 2012 Knowledge and interest of the Brazilian veterinary class in organic husbandry: preliminary survey ANGELA ESCOSTEGUY AND MELISSA BOSSARDI Welfare Institute. Brazil.www.ibembrasil.org. Email: angela@ibembrasil.org and beebossa@hotmail.com The Brazilian Society of Veterinary Medicine submitted a survey within the veterinary class to evaluate their degree of knowledge and interest in organic husbandry and food. The survey also intended to generate statistic data to provide recommendations to government, educational institutions and professional bodies to the possible need of introduction of this subject in the curriculum of veterinary courses. Two hundred and fifteen people from sixteen regions of Brazil answered the questionnaire with closed questions, from October 16 th to December 09 th , 2011. Though the survey reviled a high level of interest in the suject, the results showed that level of knowledge is low. Key words: organic husbandry, veterinary medicine, survey, curricula Introduction In Brazil, the consumption of organic food is growing, including foods of animal origin (Moraes, 2011). The market demand stimulates organic husbandry across the country creating a growing need of veterinarians with knowledge in this area. However, as it is a recent methodology it is not included in the curriculum in most schools of veterinary medicine (Mitidiero, 2010). The Vet.Org - Organic Livestock Commission linked to the Brazilian Society of Veterinary Medicine - seeks to generate information on the degree of interest, knowledge and attitude of the veterinary class concerning organic husbandry and food consumption. The goal is to generate data to support the hypothesis that this issue should be more stimulated and be included in the curricula of veterinary medicine schools in the country. Material and methodology A questionnaire was developed consisting in two parts. The first part consisted of five closed questions to obtain information about the general knowledge on the subject and habits of consumption of organic foods. The second part was formed by 15 True or False statements related to Brazilian standards. The objective of this second part was to test the knowledge concerning standards of organic husbandry production established by Brazilian legislation. From October 16 th to December 09 th , 2011, a total of 500 copies of the questionnaire were offered randomly in four locations where there was concentration of students and veterinarians. The chosen places were: two schools (one public and one private) of Veterinary Medicine and the headquarters of the Regional Veterinary Council, both in the city of Porto Alegre; and in the Brazilian Congress of Veterinary Medicine, in the city of Florianopolis. Two hundred and fifteen people from 21 to 50 years old - 101 professionals and 114 students of veterinary medicine - from 16 regions of Brazil answered anonymously the questionnaire. One hundred and fifteen questionnaires were completed by participants of the Brazilian Congress of Veterinary Medicine, 21 were answered by professionals from the Regional Veterinary Council seat and the other 79 were completed by students from the veterinary colleges. 137
