Figure 1From: Gene networks driving bovine milk fat synthesis during the lactation cycleDe novo vs. imported FA and Δ9 desaturase indexes. De novo FA synthesis (Synthesized) vs FA import (Imported) analysis (Top panel) and Δ9 desaturase indexes during lactation (Bottom panel). Synthesized = FA with 4÷14 carbons except 11:1; pooled SEM = 0.34. Imported from blood = FA with carbon chain >16 plus 15:0 and 11:1; pooled SEM = 0.31. Synthesized/Imported, pooled SEM = 0.10. Pooled SEM for Δ9 activity on 14:0, 16:0, 18:0, and trans 11-18:1 was 0.008, 0.007, 0.02, and 0.06, respectively. Statistical effect of time: P < 0.05 for all measurements except Synthesized FA (P = 0.24) and Δ9 activity on 18:0 (P = 0.77).Back to article page
