Evaluation of feeding Indigofera zollingeriana leaf meal and Sardinella lemuru fish oil on lipids metabolism of local ducks
Abstract: The objective of
this study was to evaluate the effectiveness usage of Indigofera zollingeriana
leaf meal (I) and Sardinella lemuru fish oil (L) in diets on the decreasing
levels of cholesterol and lipid metabolism of laying duck. One hundred and
forty-four Magelang ducks aged 20-32 weeks, laying periode, with an average
body weigth of 1,72±0,12 kg were used, which were divided into 6 groups of
experimental diets, 3 replications, and of 8 layers each. A completely
randomized design, 3x2 factorial design was used in this experiment. The first
factor was usage Indigofera zollingeriana leaf meal which replaced protein
soybean meal (0%, 5,5%, 11%). The second factor was usage Sardinella lemuru
fish oil (0%, 2%). The results showed that the treatment (I5.5L2) was highly
significant affected (P<0.01) the level of triglyceride, HDL, and LDL in the
blood. The treatment I0L2 significantly decrease (P<0.05) total cholesterol
of blood lipid profile and meat cholesterol. The treatment (I11L2) was highly
significantly decreased (P<0.01) egg cholesterol. The conclusion of this
study was that feeding Indigofera zollingeriana leaf meal 5.5% and Sardinella
lemuru fish oil 2% in laying duck’s diet could maintain the balance of blood
lipid profiles by lowering plasma triglycerides, LDL, cholesterol and raising
up plasma HDL and plays an important role on lipid metabolism of Magelang
laying ducks to produce eggs and meat with low cholesterol content.
