dc.description.abstractThe aim of the current study was to evaluate the effect of different forms of soybean lipids on enteric methane emission, intake, performance, digestibility and meat quality of 40 young Nellore bulls (initial body weight (BW) 444 ± 10.2 kg and 24 ± 2.1 months). The dietary treatments were as follows: NF = no dietary additional fat (46.0 g ether extract (EE)/kg diet), SO = soybean oil (62.0 g EE/kg diet), SB = soy beans (without any processing; 62.0 g EE/kg diet) and RPF = rumen-protected fat based on soybean oil (62.0 g EE/kg diet). The intake of dry matter (DM), organic matter (OM), crude protein (CP) and neutral detergent fibre (NDF) was greater in the SO diet than those fed with NF. The SO diet decreased digestibility of NDF when compared with the NF and RPF diets. The diets did not affect digestibility of DM, OM, CP or emission of enteric methane. Animals fed with SO had greater average daily gain and feed efficiency in relation to the other diets tested. The SO diet increased hot and cold carcass weights and subcutaneous fat thickness of carcasses when compared with the NF diet. The proportions of saturated and unsaturated, mono and polyunsaturated, and n-3 and n-6 fatty acids were not affected significantly by treatments. The SO diets were demonstrated to be more beneficial for animal performance compared with diets without supplemental fat.en
