Answer 2

Answer:

The breeding of dairy cows around the world is very much focused on improving production factors. Choosing only breeding methods will result in deterioration of functional markers (see review by Rauw et al., 1998), which conflicts with animal welfare (Sandøe et al., 1999). However, in the meantime, the process of dairy cows has focused on the complete inclusion of breeding and breeding purposes with a clear emphasis on functional characteristics (Mark, 2004). Although the reproductive purpose of measurement with an emphasis on functional features, the degradation of functional characteristics is not necessarily permitted (Christensen, 1998b).

Traditionally, economic values ​​in reproductive policy are obtained using profit margins (Brascamp et al., 1985; Dekkers and Gibson, 1998). When obtaining economic prices, the first objective is to increase the profitability of farmers for a dairy cattle breeding program, which is based solely on the commercial economy (e.g., Groen, 1989). In view of the increasing public concern for animal health and well-being, it is also important to include the social and behavioral aspects of animal reproduction when defining breeding policy (Groen et al., 1997; Olesen et al., 2000). Sustainable livestock production can be defined as natural production, which takes nature and biodiversity into consideration and is economically and economically viable (Torp Donner and Juga, 1997). The stability criterion can be defined by measuring each element in the breeding policy at a rate known as a nonmarket value (NV) and at a price that is traditionally obtained (commercial economic markets, EV) (Olesen et al., 2000). NV is a benefit of responding to animal and social ecological progress through the interpretation of breeding purpose. NV deductions are complex because they have to be taken at the industry level with a detailed process for the entire dairy herd from producer to consumer. Alternatively, the category level can be estimated by examining the effect of NV input by analyzing sensitivity using index calculations (Olesen et al., 2000). Although NV tools have been proposed (Olesen et al., 1999), the publication shows how to assign NV to dairy cows.
