| Popis: | Bu çalışma, miyostatin mutasyonunun belirteç yardımlı aktarım yöntemi ile Teksellerden Ramlıç koyunlarına geçirilmesi sırasında F1 ve G1 kuzularda büyüme ve ultrasonografik karkas özelliklerindeki değişimi belirlemek amacıyla yapılmıştır. 2015 - 2017 sezonlarında doğan F1 (n = 51) ve G1 (n = 99) kuzularda canlı ağırlık, vücut ölçümleri ve belgözü kasının (Musculus longissimus dorsi) ultrasonografik değerlendirmeleri üzerine kimi faktörlerin etkileri araştırılmıştır. Varyans analizi sonuçları, genotipin sütten kesim öncesi ve sonrası büyüme özellikleri üzerinde önemli (P The aim of the study was to evaluate live weights, body measurements, and real-time ultrasound carcass traits of F1 and BC1 genotypes in a marker assisted introgression (MAI) process. Effects of some factors on live weight and body measurements including ultrasonographic assessments in Musculus longissimus dorsi (MLD) were investigated at the F1 (n=51) and BC1 (n=99) cross lambs born in 2015 – 2017 period. Variance analysis showed that genotype had significant (P < 0.001) effect on pre- and post-weaning growth characteristics. The birth type had significant (P < 0.05) effect on pre- and post-weaning growth traits. Live weights at twelve months of age were higher in heavier born lambs. The growth performance of F1 lambs was between Texel and Ramlıç. Myostatin heterozygous BC1 lambs had been potentially heavier than the non-carriers and pure Texel. MLD depth and area were also statistically higher (P < 0.05) in BC1 lambs carrying myostatin than non - carriers. As a result, the beginning phase of introgression processes implemented was found to be successful |
