Choline and Choline Metabolite Patterns and Associations in Blood and Milk during Lactation in Dairy Cows
Figure 4
Relationship between plasma phosphatidylcholine concentration and either yield of phosphatidylcholine (A) or phosphocholine (B).
Each symbol represents either early ( ♦), mid (▪) and late (▴) lactation. The standards errors for the intercept and linear terms in (A) were 0.58 and 0.00007. The equation was y = a+b exp−cx with the standard errors for the fitted parameters in (B) were 0.133, 0.230, and 0.000046 for a, b and c, respectively.
