USING OF MOLECULAR GENETIC MARKERS TO IMPROVE THE TELEORMAN BLACK HEAD TSIGAI SHEEP BREED

Scientific Papers Animal Science and Biotechnologies, 2023
The investigation involved 66 Teleorman Black Head Tsigai sheep. The animals were monitored throughout their twelve controls determining the total amount of milk. The genetic markers considered by the investigation were the haemoglobin and transferrin. They were identified two genotypes (HbA/HbB and HbB/HbB) at the haemoglobin locus and eight genotypes

Meta-analysis of genetic parameters for growth traits in meat, wool and dual-purpose sheep breeds in the world using a random-effects model. [PDF]

Vet Med Sci, 2023
There is large variation in genetic parameters in literature for growth traits in sheep, so aggregation of different studies results by meta‐analysis can improve reliability of estimated parameters. A meta‐analysis with 221 articles was carried out. Decrease in Standard errors could indicate that aggregation of results of different studies improved ...
