“…However, high utility values for body size were reported from results of other discrete CEs conducted elsewhere (e.g. Kassie et al, 2009 in cows in central Ethiopia;Zander and Drucker (2008) for bulls in southern Ethiopia and bulls and cows in southern Ethiopia and northern Kenya; Ouma et al (2007) for bulls and cows in central Ethiopia and northern Kenya; Omondi et al (2008a) for bucks in Kenya;and Roessler et al (2008) for pigs in Vietnam). Therefore, sheep breeders in the production systems studied would undoubtedly benefit from incorporation of body size in any sheep genetic improvement schemes.…”

“…There are distinct breeds and breed groups suitable for diverse purposes in the different production environments/ecological zones. Furthermore, farmers in different production systems may have different trait preferences (Roessler et al, 2008) and they may also follow as diverse strategies as the agro-environments within which they perform (Reece and Sumberg, 2003). Understanding farmers' trait preferences provides insights into which traits are particularly important in their agro-ecosystem and how these can be incorporated in the design of sustainable breeding programs.…”

Identification of breeding objective traits pertinent to specific production environments with the involvement of target beneficiaries is crucial to the success of a breed improvement program. A choice experiment was conducted in four locations representing different production systems and agro-ecologies that are habitat to four indigenous sheep breeds (Afar, Bonga, Horro and Menz) of Ethiopia with the objective of identifying farmers'/pastoralists' preferences for sheep breeding traits. Following a synthesis of secondary information and diagnostic surveys, two communities per location consisting of 60 households each having at least four breeding ewes were identified. Producers' priority attributes used in the choice sets were identified through in-depth production system studies conducted from December 2007 to March 2008. On the basis of prior information, four to seven attributes were used to design choice sets with different profiles in order to capture results that mimic real life of the different communities. The attributes and levels chosen for the sheep profile were as follows: body size (large/small), coat color (brown/white/black), tail type (good/bad) for both rams and ewes; horn (polled/horned) and libido (active/poor) for rams; and lambing interval (three lambings in 2 years/two lambings in 2 years time), mothering ability (good mother/bad mother), twinning rate (twin bearer/single bearer) and milk yield (two cups per milking/one cup per milking) for ewes. A fractional factorial design was implemented to construct the alternatives included in the choice sets. The design resulted in a randomized selection of 48 sheep profiles (24 sets) for both sexes, which were grouped into four blocks with six choice sets each. An individual respondent was presented with one of the four blocks to make his/her choices. Results indicate that producers' trait preferences were heterogeneous except for body size in rams and mothering ability in ewes where nearly homogeneous preferences were investigated. In the pastoral production system, attention was given to coat color of both breeding rams and ewes, favoring brown and white colors over black. Ram libido influenced producers' decisions in Bonga, Horro and Menz areas. The influence of milk yield and twinning on respondents' decision making was high in Afar and Horro, respectively. Breeders in all areas attempt to combine production and reproduction traits as well as they can in order to maximize benefits from their sheep. The elicited measurable objective traits were used to design alternative community-based sheep breeding plans for the four indigenous sheep breeds in their production environments that have been implemented since.

“…For the theoretical approach see Olesen et al (2000) and Roosen et al (2005). This method was, for example, applied with pigs in Vietnam (Roessler et al 2008), llamas in Bolivia ) and Ankole cattle in Uganda (Wurzinger et al 2008). These user-defined breeding goals are the starting point for setting up community breeding programmes.…”

Development of organisation and planning in animal breeding: II. A review on breeding planning

et al. 2012

Breeding planning resp. planning of breeding measures as scientific discipline within animal breeding science has developed in close connection to quantitative genetics in the middle of the last century. From the beginning, breeding planning was mainly focussed on macroeconomic resp. national targets. This viewpoint has been maintained until today. This is in conflict with existing business oriented organisational structures in animal breeding. The present study gives an overview on the development of breeding planning. Based on five recent works on breeding planning it is shown that approaches have already been developed that allow for taking micro-and macroeconomic aspects into account when looking into the organisational structures. Building on these examples, the study aims at working out further approaches to breeding planning based on enterprise resource, supply chain and value added chain planning. Breeding planning combined with consideration of organisational structures and, where necessary, with organisational analysis allows to take the requirements of the private and the public sector into account. Thereto new research fields open up within animal breeding science.

“…Few studies have applied DCE in Vietnam in the domain of animal science (Costales et al, 2008;Roessler et al, 2008;Zhang et al, 2014) and its use in animal health surveillance is even more lim-ited. DCE provides quantitative evidence of the relative importance of factors influencing individual decision-making, and clarifies the trade-offs between given attributes, thus predicting the probability of uptake in specified alternatives (WHO, 2012).…”

a b s t r a c tA discrete choice experiment (DCE) is carried out to value socio-economic factors influencing the farmer's decision to report swine diseases and to assess the willingness of farmers to report swine diseases. Data were collected between March and July 2015 in two provinces in the Red River Delta, Northern Vietnam, from 196 pig producers by face-to face interview. A conditional logit model is used to measure the relative importance of the socio-economic factors and calculate the expected probability of disease reporting under changes of levels of these factors. Results of the study indicated that the likelihood of compensation and the type of culling implemented (all or only unrecovered pigs) are the two most important factors influencing farmer reporting. Compensation level, movement restriction and delay in compensation payment also have significant impacts on farmer's decision to report animal disease but they are not as important as the above factors. Three different scenarios including changes in six different factors (attributes) are tested to predict probability of animal disease reporting. Under the current situation (uncertainty of being compensated), only 4% of the farmers would report swine disease outbreak to the official surveillance system if the culling policy involves all pigs in affected farms. This number is increased to 26% if culling in affected farms is restricted to unrecovered pigs only. Ensuring certainty of compensation increases reporting probability by up to 50% and 90% if all or only unrecovered pigs are destroyed, respectively. The results of this study are important for improving the performance and sustainability of swine disease surveillance system in Vietnam.
