However, there are limited descriptions of both the wild duck population and the purpose and size of the aquatic habitats where viruses have been detected or isolated. The objective of this study was to determine if a pond of 16 hectares (39.536 acres), used for agricultural and fishing purposes and visited by approximately 9000 wild migratory ducks consisting of nine different species during the wintering stay, is suitable to support the isolation of IAV. One influenza A virus was isolated from Pekin ducks used as sentinels during the wintering stay season from September 2007 to March 2008. Only one IAV subtype was isolated from 9 of the 88 samples collected from the sentinel ducks over seven months, and the molecular characterization of this isolate revealed an H6N2 virus subtype. Based on this information, it is suggested that a pond such as the one in this study provides a suitable biological setting to support the presence of IAV, but the minimum biological environment to isolate the influenza A virus is still unknown. <![CDATA[Non-inferiority trial of two commercial zilpaterol HCl brands in <em>Bos indicus</em> cattle under humid tropical conditions]]> Abstract Commercial availability of a generic zilpaterol HCl (ZH) premix preparation for beef cattle in Mexico motivated a non-inferiority trial vs the reference preparation. The trial was conducted on zebu-type cattle (Bos indicus) under humid tropical conditions. Meat production and basic meat quality were assessed for 810 zebu bulls, aged 18-22 months and weighing 430 to 490 kg. Bulls were randomly assigned into one of three groups: ZHg, treated with the generic ZH (Zipamix®) preparation; ZHr, treated with the reference ZH (Zilmax®) preparation, and Cg, the untreated control group. Housing, shade surface, feeding and water availability were highly homogeneous between the animals’ pens. Results for the measured productive and meat quality parameters showed that both ZH-treated groups had higher values than the Cg (P &lt; 0.05), and differences between the ZHg and ZHr groups were not statistically significant, thus fulfilling the criteria of a non-inferior ZH preparation. In this assay, ZH supplementation did not modify the amounts of moisture, fat, protein or ash in the Longissimus dorsi muscle compared with the meat from non-supplemented animals, and the overall meat acceptability was unaffected (P &gt; 0.05). <![CDATA[Sustainable Development Goal #3, “health and well-being”, and the need for more integrative thinking]]> Abstract Recently, the United-Nations adopted 17 sustainable development goals for the 2030 Agenda. The Sustainable Development Goal (SDG) 3 “Ensuring a healthy life and promoting well-being for all ages” is one of the most transversal goals, which is interconnected with the other SDGs. The health and well-being are the aim of this goal and also, they are the result of other goals that empower people to develop better in different social, economic and productive areas. The SDG 3 is a multiple and universal resource on which sustainable development policies can be based, in particular for the most needed countries, and can lead to the sustainable maintenance of well-being and health. However, SDG 3 faces a high sectorization, so there is a risk of not being able to achieve the stated objectives. Only a national and international reflection on human population and animal health surveillance devices, environmental health, implementation of appropriate indicators and specific research funding will ensure the balance between the legitimacy of society’s demands and the needs of scientific and medical excellence. The health and well-being indicators that are needed to achieve the agenda goals are based on reliable and relevant quantitative data, which are currently rare or even non-existent in some regions. Therefore, it is now necessary to initiate a more integrative international animal and public health and research strategy in order to collect new data, particularly those relating to current emerging infectious diseases that affect public and animal health, especially in developing countries.
