Estimation of Genetic Distances and Horse Distinguishing Factors in North Sumatra through Craniometric Analysis

Introduction

Horses have been an integral part of human society for thousands of years, serving as a mode of transportation, a source of food, and a symbol of power and status. In Indonesia, horses are an important part of the country's cultural heritage, with many breeds found throughout the archipelago. However, the genetic diversity of horses in Indonesia is a concern, with many breeds facing the threat of extinction due to factors such as habitat loss, disease, and human activities. In this study, we aim to explore the genetic distances and factors that distinguish horses in four districts in North Sumatra, namely Karo Regency, Humbang Hasundutan Regency, North Tapanuli Regency, and Samosir Regency.

Methodology

This study began in July 2016 and involved various analyzes such as descriptive analysis, discriminant analysis, canonical analysis, main component analysis, genetic distance measurement, and phylogenic tree manufacturing. The study aimed to collect data on the skull dimensions of horses in the four districts, including the length and width of the skull, as well as the length of the jaw. The data was then analyzed using various statistical methods to identify the genetic distances and factors that distinguish horses in the four districts.

Results

The results of the study showed that horses in Karo Regency have the highest skull length, while Samosir Regency recorded the lowest length of the skull. In addition, the highest width of the skull width was also found in Karo Regency, and the lowest average is in Samosir Regency. North Tapanuli Regency stands out with the highest average skull, while the lowest average is in Samosir Regency. For the length of the jaw, the district with the highest average is North Tapanuli Regency, while Samosir Regency recorded the lowest value.

The highest diversity coefficient was found in horses in North Tapanuli Regency, showing greater genetic variation compared to horses in Humbang Hasundutan Regency which has the lowest diversity. The length of the skull is identified as the main variable that distinguishes between horses in the district under study. In terms of genetic distance, the horses that are the closest genetic come from Karo Regency and North Tapanuli Regency, while the farthest genetic distances occur between horses in Karo Regency and Horses in Samosir Regency.

Discussion

Kraniometric analysis, which is used in this study, becomes a very important tool for understanding morphological variations in horses. By analyzing the skull dimension, researchers can judge how environmental factors, breeding patterns, and genetic history can affect the physical appearance of horses in the area. Horse morphology, especially the size and shape of the skull, is often related to the adaptation to the environment and the selection of humans. For example, horses with a larger skull may be better in terms of durability and strength, so it is preferred for various agricultural or sports activities.

The genetic distance found between districts also provides insight into the potential for breeding and genetic preservation. By knowing which areas have higher genetic similarities, breeding efforts can be focused on maintaining or improving the genetic quality of horse in North Sumatra. Overall, this research not only provides a clearer picture of the variation of horses in North Sumatra but also helps in informing a better conservation and breeding strategy for these animals.

Conclusion

This study provides a comprehensive analysis of the genetic distances and factors that distinguish horses in four districts in North Sumatra. The results of the study show that horses in Karo Regency have the highest skull length, while Samosir Regency recorded the lowest length of the skull. The highest diversity coefficient was found in horses in North Tapanuli Regency, showing greater genetic variation compared to horses in Humbang Hasundutan Regency which has the lowest diversity. The length of the skull is identified as the main variable that distinguishes between horses in the district under study.

The findings of this study have important implications for the conservation and breeding of horses in North Sumatra. By understanding the genetic distances and factors that distinguish horses in the four districts, breeding efforts can be focused on maintaining or improving the genetic quality of horse in North Sumatra. This study is expected to be a reference for other researchers and practitioners in the field of horse farms, as well as encouraging efforts to preserve the genetic diversity of horses in Indonesia.

Recommendations

Based on the findings of this study, the following recommendations are made:

Conservation efforts: Efforts should be made to conserve the genetic diversity of horses in North Sumatra, particularly in areas with high genetic variation such as North Tapanuli Regency.
Breeding programs: Breeding programs should be established to maintain or improve the genetic quality of horses in North Sumatra, particularly in areas with high genetic similarity such as Karo Regency and North Tapanuli Regency.
Research and development: Further research and development should be conducted to understand the genetic distances and factors that distinguish horses in North Sumatra, as well as to develop effective breeding and conservation strategies for these animals.

Limitations

This study has several limitations, including:

Sample size: The sample size of this study was limited to four districts in North Sumatra, which may not be representative of the entire region.
Data collection: The data used in this study was collected through descriptive analysis, discriminant analysis, canonical analysis, main component analysis, genetic distance measurement, and phylogenic tree manufacturing, which may not be comprehensive.
Generalizability: The findings of this study may not be generalizable to other regions or populations of horses.

Future Directions

Future studies should aim to:

Increase sample size: Increase the sample size of the study to include more districts and populations of horses in North Sumatra.
Improve data collection: Improve the data collection methods used in this study to include more comprehensive and accurate data.
Develop effective breeding and conservation strategies: Develop effective breeding and conservation strategies for horses in North Sumatra based on the findings of this study.

Conclusion

In conclusion, this study provides a comprehensive analysis of the genetic distances and factors that distinguish horses in four districts in North Sumatra. The results of the study show that horses in Karo Regency have the highest skull length, while Samosir Regency recorded the lowest length of the skull. The highest diversity coefficient was found in horses in North Tapanuli Regency, showing greater genetic variation compared to horses in Humbang Hasundutan Regency which has the lowest diversity.
