Pengaruh penambahan kolin klorida pada pakan terhadap kadar kolesterol dan lipoprotein darah sapi perah laktasi

The purpose of this study was to evaluate the effects of choline chloride addition in feed on cholesterol, low density lipoprotein (LDL), and high density lipoprotein (HDL) levels in blood of lactating dairy cow, as indicator of lipid anabolism in the body. Eight of lactating dairy cows (61 to 91 days in milk; 2 nd lactation period and 456 ± 31 kg of BW average as equal to 99 ± 5 kg BW 0 . 75 ) were fed total mixed diet containing Napier grass and concentrate (40:60) and additive 30 g/d choline chloride 60% corn-cob as 18 g/d choline chloride (as equal to 0.02 % BW 0 . 75 ). The experiment was set as cross-over designs with two experiments and eight replications. The treatments were T 0 = 0 g/d choline chloride and T 1 = 30 g/d choline chloride, within 2 periods in which each period was 4 weeks and the data was analyzed using analysis of variance (ANOVA). The results showed that the addition of 30 g/d choline chloride in feed did not affect (P>0,05) the cholesterol, LDL and HDL levels in blood of lactating dairy cows. The conclusion of this study was the choline chloride addition in feed did not increase cholesterol, LDL, and HDL levels in blood of lactating dairy cows as the indicator of lipid anabolism.
