Abstract

Breed selection toward sustainable ruminant production should consider the breed that have high feed efficiency in the same time produce low methane emission. The study was conducted to evaluate the productivity and estimated methane production of six different breed of sheep fed on total mixed ration contained CP 16% and energy metabolism 2.3 Mcal/kg. The evaluation of this study involved breed of sheep developed in Indonesian Research institute for animal production (IRIAP), consisting of 1. Compass Agrinak (CA); 2. Garut Composite (KG); 3. Barbados cross (BC); 4. St Croix (SC); local Sumatera (SMT), and 6. Lokal Garut (GL) sheep. Five heads of post weaning male sheep from each breed were used in the study. Study were conducted in randomized complete block design. Feed consumption was highest (P<0.05) in BC sheep (744.62g/day), while average daily gain of KG was the highest (P<0.01). The best feed efficiency was KG sheep (0,173) which was similar to SC. Estimated methane production was similar among the sheep breeds with the average was 24.73 mol/100mol. In conclusion the best performance of the sheep breed was KG sheep, even though its methane production was similar among the breeds but it has highest ADG and feed efficiency.
