    ASBTRACT Betaine is one of feed additive as a donor of methyl groups (CH3) and can release the group at a transmethylation reaction to synthesize a variety of important metabolic substances such as carnitine, creatine, and lecithin. Betaine is a tertiary amine formed from the oxidation of choline (Wang et al., 2004) and is involved in methionine sparing, osmoprotective and fat distribution (Metzler- Zebeli et al., 2009). Methionine is an essential amino acid required for protein synthesis and fat metabolism. According to Wang et al. (2004), when the number of methionine on feed is inadequate, methionine supplementation is used for protein synthesis, while more efficient betaine as a methyl donor involved in the synthesis of carnitine, which is essential for beta-oxidation of long chain fatty acids. Based on this, the effect of betaine supplementation can be seen by looking at the levels of protein and fat in the blood profile. This study aimed to determine the effect and the most optimum level of betaine supplementation on the deficient ration of methionine to the protein amount and blood lipid quail. This research was conducted at the Livestock Poultry Cage of Animal Husbandry Department, Faculty of Agriculture, Sebelas Maret University Surakarta, located in the Jatikuwung village, district of Gondangrejo, Karanganyar for four months starting from April to July 2012. Analysis of blood profile was performed at the Laboratory of Clinical Pathology, Faculty of Veterinary Medicine, Gadjah Mada University. The material used was 340 quails of 4-weekold female quail with a mean initial body weight was 98.31 ± 8.67 g / bird and the coefficient of variation (CV) 8.82%, divided into 4 treatment groups that were repeated 5 times and each replication consisted of 17 individuals. The research was carried out experimentally using a completely randomized design (CRD). Ration composed of yellow corn, rice bran, soybean meal, fish meal, cassava, limestone, dicalcium phosphate, premix and NaCl. Treatment given was the basal ration of deficient methionine (0.3%) that was supplemented betaine as 0 (control), 0.07; 0.14 and 0.21%. Betaine supplementation performed by swapping (expense) components of cassava with betaine in accordance with the procedures of Wang et al. (2004). Basal ration formulation was made to meet the needs of quail in the production phase as recommended by SNI (2006), except for methionine content. The variables measured were total plasma protein (TPP), albumin, low density lipoprotein (LDL) and blood high density lipoprotein (HDL) quail. The results of analysis of variance showed that betaine supplementation to the level of 0.21% had no effect on all observed variables. The conclusions that can be drawn from the research was that betaine supplementation to the level of 0.21% deficient ration of methionine did not affect the levels of protein and blood lipids such as TPP quail, albumin, LDL and HDL. Keywords: quail, betaine, methionine, blood proteins, blood lipids xi
