Three 4x4 Latin square experiments of methane emissions by different oils supplementation to Lai Sind male cattle were carried out. In Exp 1 average live weight of Lai Sind male cattle was 180 ±11.2kg (X±Std) and 4 treatments were rice straw and concentrate, rice straw, concentrate + 1% fish oil, rice straw, concentrate + 2 % fish oil and rice straw, concentrate + 3% fish oil corresponding to the CFO0, CFO1, CFO2 and CFO3 treatments. In Exp 2 the average live weight of Lai Sind male cattle was213±27.6kg (X±Std) and4 treatments were rice straw and concentrate (CCO0), rice straw, concentrate + 1% coconut oil (CCO1), rice straw, concentrate + 2 % coconut oil (CCO2) and rice straw, concentrate + 3% coconut oil (CCO3). In Exp 3 the average live weight was 267 ± 31.2 kg (X±Std) and the treatments were rice straw + concentrate ground nut oil (GO_0), rice straw, concentrate + 1% ground nut oil (GO_1), rice straw, concentrate + 2 % ground nut oil (GO_2) and rice straw, concentrate + 3% ground nut oil (GO_3). In all three experiments, rice straw was fed ad libitum, while concentrate (14.4 % CP and 3000 Kcal/kg DM) was fed at a level of 1 kg per 150 kg LW. The experimental period was 14 days with 7 days for adaptation and then 7 days for sampling. CH 4 and CO 2  production, which will be measured over a 24 h period with two consecutive days, while the cattle heads were in ventilated hood. Concentrations of CH 4 and CO 2 in chamber were automatically recorded during the measurement period by using Infrared Gas Analyzer, Model IR200, Style: S3; YOKOGAWA, Japan. The results indicated that in Exp 1 Supplementing catfish oil to basal rice straw diets of cattle from 1 to 3 % (DM basis) was gradually reduced methane production and did not cause any negative effects on feed intakes, nutrient digestibility and rumen parameters. The studies of supplementation of catfish oil more than 3 % in the cattle diets should be considered to evaluate GHG emissions and growth performance for farmers’ practices. In the second experiment the supplementation of coconut oil to cattle diets from 1 to 3 % (DM basis) gradually reduced methane production and did not have any negative effects on nutrient digestibility, however a reduction of feed and nutrient intake was found. However, in Exp 3 we did not find any significant difference in methane production and nutrient digestibility among the 0, 1, 2 and 3% ground nut oil treatments. For three experiments the CO 2 emissions were proportionally linear relationship with CH4 production. The conclusion was that supplementation of fish oil and coconut oil should be considered to reduce methane production in cattle raising.
