The following are aspects were discussed in this chapter: Domestication of goats – checking on when the goats were first domesticated and for what purposes; Current goat industry - looking on the contribution of goats economically; Conservation of domestic animal diversity - looking on the importance of conserving indigenous animals since some of them are under threat of extinction; Male goat fertility – discussing male fertility indicators; Characterisation approaches - different approaches to be followed when characterising indigenous species; and Phenotypic and genetic characterisation of indigenous goats.

SummarySome countries have introduced a requirement for genetic impact assessments prior to granting permission for the import of new exotic livestock breeds. However, the merits of such a system are not universally accepted. During February 2007 a discussion on the subject took place on FAO's Domestic Animal Diversity Network (DAD-Net) electronic forum. This paper presents a description of how the discussion developed, and a summary of the issues raised. Arguments both for and against requiring impact assessments were put forward. Those opposing such measures focused on the risks of limiting access to animal genetic resources (AnGR), and questioned the benefits of government interference. Practical constraints to implementation and enforcement were also noted. Counter arguments pointed to the potential for avoiding the loss of valuable AnGR, and stressed governments' responsibilities to intervene where necessary to promote sustainable development, to defend the interests of the poor, or to protect national heritage. The debate ranged more widely — encompassing the respective roles of local and exotic AnGR in different regions of the world and in different production systems.

Primary Focus

In the context of domestic animal diversity, the term "breed" is conventionally used for all recognized populations. There are in total about 5000 breeds, a small proportion of which are in planned programs for genetic improvement, while about 30% are at risk of extinction. The primary focus is on the conservation of breeds, including management for better utilization (breeding programs) and conserving those at risk, with the aim of minimizing the loss of among breed diversity. The majority of the world's breeds are in the developing countries, with production environments that are low to medium input and high stress, and each may be expected to have adapted to its specific environment. Empirical evidence strongly supports the expectation that the genetic basis of population differentiation for fitness traits will be nonadditive, with different adaptive gene complexes evolved in each breed. Genetic improvement programs therefore should start with an adapted population, with selection then for production traits. As not all breeds can be conserved, priorities must be determined. Suggested criteria (breed divergence, risk of breed extinction, breed "merit," and within-breed variation) are presented and evaluated. Similar approaches may be appropriate for the conservation of genetic diversity of forest trees.

Watch List

SUMMARYThe recently published World Watch List for Domestic Animal Diversity (WWL-DAD) provides the first comprehensive list of endangered livestock breeds worldwide (FAO/LTNEP 1993). This document will function as a global early warning system to help prevent the erosion of livestock genetic resources. Seven species are covered, namely ass, buffalo, cattle, goat, horse, pig and sheep. Within these species, breeds at risk are defined as critical (The Critical Breeds List) or endangered (The Endangered Breeds List) based on the number of breeding females. Although the statistics for these seven species are still incomplete at the time of going to press, over 390 breeds are already known to be at risk.

Historic Data

Abstract. The Farm Animal Biodiversity Network (FABISnet) is a new biodiversity network for collecting domestic animal breeds data from the European countries. Data are collected on National, Regional and Global level and can be automatically transferred between the levels. As a successor of the Animal Genetic Data Bank of the European Association for Animal Production (EAAP-AGDB) and the Domestic Animal Diversity Information System (DAD-IS) of the Food and Agricultural Organization (FAO), it has taken their historic data and integrated them in a network of databases. However, the data are incomplete. For example the general description of 57% of the registered European breeds are very sparse and for more than 3900 breeds the population size and structure statistics are outdated. A set of 13 management support reports and a methodology for their application has been developed. The reports present summarized information about the degree of completeness of the breeds descriptions by country, missing or incomplete population records, reminders for updating data and the status of data translation. Various monitoring/reporting tasks of the National and Regional Coordinators for management of animal genetic resources can be organized in a systematic manner using these reports. Such an organizational scheme can reduce the time spent in completing data and improve the content of each database in the network.

Strategic Policy

These Guidelines are for use in assisting the development of Country Reports as strategic policy documentation covering the state of animal genetic resources, of the art and capacity to manage these resources, and of country needs and priorities.The Guidelines serve to help support conduct of the country-driven State of the World Process for Animal Genetic Resources, preparation for which is being co-ordinated globally by FAO. The Country Reports will serve as the formative documentation in this Process and the involvement of all stakeholders in the development of these Reports is strongly encouraged.A broad range of experts and of countries have contributed to developing the Guidelines, which are designed for use in conjunction with the State of the World Reporting Module of the Domestic Animal Diversity Information System http://www.fao.org/dad-is/ following training and in-country coordination of action.
