Fatty acids in the milk of goats after cessation of lactation.
Regular hand milking of six goats was discontinued after 32-35 weeks of lactation. A few days after milking out ceased, the concentration of triglyceride in peripheral blood plasma increased. Over a period of weeks, the concentration of triglyceride in small samples of fluid taken from the teat canal fell gradually. Lipase activity of the milk fluid was temporarily reduced shortly after milking out ended, but, despite this, its concentration of free fatty acids increased. It is suggested that free fatty acids are released during clearance of milk triglyceride from residual fluid in the mammary gland after cessation of lactation.
