Animal genetic resources in Brazil: result of five centuries of natural selection

Brazil has various species of domestic animals, which developed from breeds brought by the Portuguese settlers soon after their discovery. For five centuries, these breeds have been subjected to natural selection in specific environments. Today, they present characteristics adapted to the specific Brazilian environmental conditions. These breeds developed in Brazil are known as Crioulo, local, or naturalized. From the beginning of the 20th century, some exotic breeds, selected in temperate regions, have begun to be imported. Although more productive, these breeds do not have adaptive traits, such as resistance to disease and parasites found in breeds considered to be native. Even so, little by little, they replaced the native breeds, to such an extent that the latter are in danger of extinction. In 1983, to avoid the loss of this important genetic material, the National Research Center for Genetic Resources and Biotechnology (Cenargen) of the Brazilian Agricultural Research Corporation (Embrapa) decided to include conservation of animal genetic resources in its research program Conservation and Utilization of Genetic Resources. Until this time, they were only concerned with conservation of native plants. Conservation has been carried out by various research centers of Embrapa, universities, state research corporations, and private farmers, with a single coordinator at the national level, Cenargen. Specifically, conservation is being carried out by conservation nuclei, which are specific herds in which the animals are being conserved, situated in the habitats where the animals have been subjected to natural selection. This involves storage of semen and embryos from cattle, horses, buffaloes, donkeys, goats, sheep, and pigs. The Brazilian Animal Germplasm Bank is kept at Cenargen, which is responsible for the storage of semen and embryos of various breeds of domestic animals threatened with extinction, where almost 45,000 doses of semen and more than 200 embryos exist presently. An important challenge for this program is to make the different segments of society realize the importance of the conservation of animal genetic resources.

What's on the menu? Options for strengthening the policy and regulatory framework for the exchange, use and conservation of animal genetic resources

This paper addresses major issues and challenges for Animal Genetic Resources (AnGR) and the livestock sector, as well as options for further development of policies or regulatory approaches. Three main areas were identified, i) how we can halt the further erosion of genetic diversity and promote sustainable breeding and use, ii) whether there is a need to regulate the exchange of genetic material and iii) how to balance different systems of rights (e.g. sovereign rights of nations, intellectual property rights, communal rights or rights of livestock keepers). To halt further erosion, complementary ex-situ and in-situ conservation approaches are needed and breeding and marketing of local breeds should be strengthened. Secondly, recognizing the importance of the exchange of AnGR, broad access and responsible and equitable exchange mechanisms should be further promoted. Thirdly, regarding intellectual property rights, there is a need to adapt the application of the patent system to the special circumstances inherent in animal breeding. Moreover, possible sui generis systems should be further explored in order to better balance different rights systems. Rather than developing a new or adapted internationally legally binding framework, the intergovernmental process under FAO may instead wish to focus, in the first instance, on the development of voluntary instruments to strengthen national policies and the implementation of action at national levels. Debates and developments related to international agreements in the crop sector have also tended to frame the debate for AnGR. However, before launching into a discussion on whether or not an ‘FAO Animal Treaty’ would be needed, one should first of all clarify the problems to be dealt with and regulated via an international regime.

ANIMAL GENETIC RESOURCES CONSERVATION PROGRAMME IN BRAZIL

The Brazilian Agricultural Research Corporation (EMBRAPA), through the National Research Centre for Genetic Resources and Biotechnology (CENARGEN), created the National Research Programme for Genetic Resources in 1974, but at that time only plant resources were included. A few years ago, the need for conservation of animal genetic resources in Brazil became clear, and the lack of necessary documentation and evaluation was recognized. Finally, in 1981, CENARGEN decided to include animal genetic resources in its Research Programme. In the case ofcattle, actions are being taken to save the “Criollo” before it is too late as it is rapidly disappearing by indiscriminate crossbreeding. There is already considerable information on the “local” livestock breeds, strains and varieties in Brazil. A number of these breeds, strains or varieties that are in danger of extinction have been identified, and are being documented and specifically evaluated, particularly to determine if they possess any unique or special inherited characteristic that would warrant their conservation. Until such evaluation is completed, steps are being taken to ensure preservation of these populations. More recently, the programme ineluded other species such as: buffaloes, pigs, sheep, goats, horses and donkeys.
