Abstract

Aims of this present study were to investigate the effects of dietary rumen-protected choline (RPC) on lactation performance and plasma parameters in early lactation cows. Four healthy, multiparous Holstein cows with similar parity, expected calving date, body weight and milk yield were used in a 4×4 Latin square experiment. The four cows were fed diets supplemented with 0, 30, 60 or 90 g/d RPC (the contents of choline were 0, 7.5, 15.0 and 22.5 g), respectively. The experiment was divided into four 15-day periods. The results showed that milk yield, lactose and milk protein contents and those yield were not influenced by RPC supplementation level (P>0.05). Milk fat percentage was increased with the PRC supplementation level increasing (P<0.05), and the higher milk fat percentages were observed when 30 and 60 g/d RPC were supplemented, but there were no significant difference between them (P>0.05). PRC supplementation did not affect glucose, high-density lipoprotein, β-hydroxybutyric acid, triglycerides and cholesterol content in plasma (P>0.05), and had a trend to increase plasma low-density lipoprotein content (P>0.05). PRC supplementation decreased plasma non-esterified fatty acids content (P=0.05), and when PRC supplementation was 60 g/d, plasma non-esterified fatty acids content was gotten to the lowest level, and significantly lower than that of the control (P>0.05). Results of the present study indicate that dietary PRC for early lactation cows may increase the output of the liver fat, enhance the metabolism of fatty acids in the peripheral tissue, and then contributes to milk fat synthesis and reduces the risk of fat deposition in the liver.

Key words： dairy cows; choline; supplementation level; milk fat; plasma non-esterified fatty acids
