Effect of fermentable liquid diets based on wet brewers grains on performance and carcass characteristics by growing pigs. J. Appl. Anim. Res., 36: 271–274. To evaluate growth and carcass characteristics of pigs fed graded levels of fermentable liquid diets (FLD) based on wet brewers grains (WBG), 32 Landrace × York male pigs (32±4 d; 9.7±1.2 kg) were allotted to one of the four treatment diets containing 0, 15, 30 and 45% WBG (dry matter basis). Animals were weighed every 20 d and dry matter intake (DMI) by pen was recorded daily. At 95 kg pigs were slaughtered and carcass characteristics were measured. Average daily gain of pigs was significantly different among treatments being higher for 0% WBG (660 g day−1) followed by 15% (553), 30% (537) and 45% (507), similar trend was observed for DMI (1895 g day−1, 1881, 1823 and 1771, respectively). Moreover, carcass dressing was significantly different among treatments (71.5%, 70.1, 68.9 and 67.8, respectively). Even though, growth performance was negatively affected by FLD, feeding costs were reduced even when the fattening period was longer. It is suggested that animals may be fed on 30% WBG diets in post-weaning periods and 30 or 45% during growing and finishing periods.
