Abnormal haemoglobin in Finnsheep.

Area of Science:

• Veterinary Science
• Animal Genetics
• Biochemistry

Background:

• Hemoglobin variants can impact animal health and productivity.
• Previous reports indicate specific hemoglobin types in Norwegian and Merino sheep breeds.

Purpose of the Study:

• To report the identification of an abnormal hemoglobin type in Finnish sheep.
• To compare this novel hemoglobin type with known variants in other sheep breeds.

Main Methods:

• Hemoglobin analysis was performed on affected Finnish sheep (ewe and lamb).
• Comparative analysis with documented hemoglobin types, including HbC, was conducted.

Main Results:

• An abnormal hemoglobin type was detected in one Finnish ewe and one of her lambs.
• The identified hemoglobin appears similar to HbC previously reported in Norwegian and Merino sheep.

Conclusions:

• A novel abnormal hemoglobin type exists in the Finnish sheep breed.
• This finding suggests a potential shared genetic basis or convergent evolution of hemoglobin abnormalities across different sheep populations.
