Acetate and stearate utilization by lactating cows fed high grain-restricted roughage rations

, : Acetate and stearate utilization by lactating cows fed high grain-restricted roughage rations. Journal of Dairy Science 55(10): 1481-1486

For 6 to 8 weeks 2 Holstein cows were given a control diet of maize silage, long hay and concentrate in ratio 50:15:35 or a diet of long hay and concentrate 15:85. Intravenous infusions of acetate-14C and stearate-3H were given for 6 to 8 h and blood, milk and adipose and liver tissues were analysed. Compared with the control the experimental diet decreased milk fat content, increased activities of 14C and 3H in milk and adipose tissue and decreased the triglyceride content of milk lipids. The experimental diet increased the percentages of 14C and 3H in polar lipids and cholesterol and decreased those in triglycerides of milk fat. In liver lipids free fatty acids decreased and polar lipids and cholesterol increased slightly in cows given the experimental diet. Triglycerides of serum lipids decreased when the experimental diet was given. The control and experimental diets had different effects on the distribution of milk fatty acids.
