Abstract: This experiment was conducted to evaluate the effect of Keji beling leaf extract on growth performance and fat accumulation in broiler chickens. Twenty one-day old female broilers were divided into 2 groups with 4 replicates of 2 broilers each. Broilers were kept in cages and supplemented with the extract for 21 days. Treatment 1 was control with no keji beling addition, and treatment 2 was 50 g leaf extracted with one liter of water. The extract was supplemented to drinking water. Water and feed were fed ad libitum. The results showed that keji beling extract had no effect on body weight, feed intake, feed conversion ratio, the weight of carcass, heart and intestine (P<0.05), but it reduced spleen weight, fat accumulation in the body, liver and abdomen (P<0.05) and increased the weights of liver and gizzard (P<0.05). It was concluded that keji beling extract was effective for reducing fat accumulation in broilers without disturbing their growth characteristics (Jurnal Peternakan dan Lingkungan, 6 (2): 10-14, 2000)

Abstract: The effect of tu-chung (Eucommia ulmoides, Oliver) leaf meal on reducing lipid accumulation in chickens fed 1% cholesterol containing diet was studied. Forty female White Leghorn chickens aged 56 days were weighed and divided into four groups of ten chickens, and fed diets with or without 1% cholesterol which were supplemented with 0 and 5% tu-chung. Tu-chung supplentation to the diet without cholesterol increased acetyl-CoA carboxylase (P<0.01) but decreased 3-hydroxy-3-methylglutaryl-CoA reductase activities (P<0.01) with no effect on fatty acid synthetase activities. However, its supplementation to the diet with cholesterol had no effect on these three enzyme activities as compared with the cholesterol containing diet without tu-chung. Tu-chung supplenetation to the diet without cholesterol increased hepatic triglyceride (P<0.01), whereas its supplentation to the diet with cholesterol decreased it (P<0.01). Tu-chung supplementation to the diet with cholesterol decreased plasma cholesterol ester, free cholesterol, phospholipids (P<0.05) and triglyceride (P<0.01) as compared with the cholesterol containing diet without tu-chung. Supplementation of tu-chung to the diet without cholesterol decreased plasma free cholesterol (P<0.05). It concluded that tu-chung leaf meal reduced an increase in lipid accumulation in chikens stimulated by 1% cholesterol feeding (Asian-Aust. J. Anim. Sci., 13 (12): 1758-1763, 2000)
