Farklı Laktasyon Dönemlerindeki Damascus Keçilerinde Süt Özellikleri: 2. Yağ Asidi Profili ve Onunla İlişkili Bazı Lipogenik Genlerin Ekspresyon Seviyeleri

Bu çalışmada, laktasyon periyodundaki Damascus keçilerinde süt yağ asidi profili ve süt somatik hücrelerinde bazı lipogenik genlerin aktiviteleri değerlendirilmiştir. Ayrıca, laktasyon boyunca yağ asidi profili ile lipogenik genler arasındaki ilişki araştırılmıştır. Keçilerin laktasyon dönemleri erken, orta ve geç laktasyon dönemi olarak üçe ayrılmıştır. Yağ asidi profilinin yanı sıra sütte FASN, SCD, ACACA, SREBPF1 ve PPARy genlerinin ekspresyon düzeyleri belirlen-miştir. Süt örneklerinde yağ asidi içeriğinin laktasyon boyunca değiştiği tespit edilmiştir (P

Milk Traits of Damascus Goats at Different Lactation Stages: 2. Fatty Acid Profiles and Related Lipogenic Genes Expression Levels*

In the present study, goat milk fatty acid profile and some of the lipogenic genes activities in milk somatic cells were evaluated during the lactation periods in Damascus goats. Relationship between fatty acid profile and lipo-genic genes during the lactation were also investigated. The lactation periods of goats were divided to three stages as early, mid and late lactation. Beside fatty acid profile, FASN, SCD, ACACA, SREBPF1, and PPARγ genes expression levels were determined in milk. It was determined that fatty acid contents of milk samples changed during the lactation (P
