Clustering Limousin Candidate Bulls Based on Their Measured Production Traits and Genomic Scores | Chapter 9 | Emerging Issues in Agricultural Sciences Vol. 5

 This unit aimed to outline type categories of Limosin breeding bulls by cluster reasoning, based on their main performance test results, both calculated in the test station and obtained by DNA money. Production control and performance tests are inevitable, main parts of the breeding project. Various techniques maybe applied during these, but it is clear to use accurate, fast, and standardised means for all traits important in accordance with the breeding aim. The result of purebred Limousin candidate bulls (n = 40) were analysed betwixt 2018-2020. Candidate bulls were kept in limited groups (2-9) at the test station, fed with grassland hay, alfalfa at one's pleasure and dosed food. Traits studied were the following: finishing live pressure, daily burden gain during the test (g/day) and genomic scores (GS) for 8 result and reproduction characteristics (growth vigor, brawn, frame size, calving trouble, bone, milk result, pelvis). Different types within breeds can produce otherwise in various atmospheres, suitable for different pick criteria and either and animal is used in sire line or in motherly one further depends on type. The animals arranged into the first cluster showed high progress capacity and superior growth intensity accompanying good frame size, but as long as with slightly less benign bone excellence. The frame size of the individuals owned by the second and third groups is not superior, however, their cartilage fineness is remarkable. Applying of the K-way cluster analysis can specify the breeders fast and useful information. These types of studies can help to understand the friendships among given parts of the type.
