Abstract Feed additives are commonly used in finishing pig diets to improve growth performance and carcass characteristics; however, data is limited on the interaction of various feed additives. The objective of this study was to determine the individual and combined effects of a phytogenic feed additive (Aromex® Pro) and narasin (Skycis®) on finishing pig growth performance and carcass characteristics. The study was conducted at a commercial research facility using a RCBD with 4 dietary treatments: Control (no Aromex® Pro or Skycis®); Aromex (as Control with 90.7 g/ton Aromex® Pro); Skycis (as Control with 13.6 g/ton Skycis®); Aromex + Skycis (as Control with 90.7 g/ton Aromex® Pro and 13.6 g/ton Skycis®). Diets were based on corn, soybean meal, and corn germ meal and were fed using a 3-phase program. Diets were formulated to the same nutrient levels across treatments that met or exceeded nutrient recommendations (NRC, 2012), with the feed additive added at the expense of corn. Pigs were placed on test at 40.6 ± 4.7 kg and harvested in 2 equal groups at 122.4 ± 2.2 kg. Thirteen blocks were used with pens of 34 pigs for 1,768 total pigs. Data were analyzed using PROC MIXED of SAS with pen as the experimental unit, fixed effect of treatment, and random effect of block. There was no effect (P > 0.05) of treatment on start or end weights, overall ADG (live or carcass weight), overall ADFI, or any carcass characteristics. Overall G:F (live and carcass weight) for Aromex and Skycis was similar (P > 0.05) to each other and greater (P < 0.05) than Control. Aromex + Skycis had G:F (live and carcass weight) similar to Control and Aromex, but less than Skycis. In conclusion, including Aromex® Pro and Skycis® in finishing diets improved feed efficiency, but those effects were not additive.

Thirty-six growing-finishing pigs, with an average initial weight of 24.8 kg ± 2.6 SD, were allocated to six groups to determine the effect of fish silage and fish fat in the diet on performance, carcass characteristics and sensory quality. The treatments were either a control diet, or one of three diets containing 50 g kg−1 fish silage and different levels of fish fat (2.5, 5.5 or 9.5 g kg−1). The diets were either fed until the time of slaughter (treatments CO, FSA1, FSB1 and FSC1), or until 60 kg liveweight followed by the control diet (the diets with 5.5 [treatment FSB2] and 9.5 g kg−1 fish fat [treatment FSC2]). Pigs were slaughtered at 98.7 kg ± 4.5 SD. No significant differences in growth performance or carcass quality were found among diets. The contents of the fatty acids C20:1 and C22:6 in the subcutaneous fat was increased by the dietary inclusion of fish silage. The total level of omega-3 fatty acids were highest for the 9.5 and the 5.5 g kg−1 fish fat diets when they were fed until slaughter. High blood plasma levels of vitamin E in pigs fed diets containing fish silage and 5.5 g kg−1 fish fat may explain these differences, and thus indicate the importance of vitamin E status when feeding diets containing fish silage and fish fat. The diets containing 2.5 and 9.5 g kg−1 fish fat until slaughter caused off-flavour of bacon after both 1 and 6 mo of frozen storage, and of loin muscle after 6 mo frozen storage. Curiously, the diet with fish silage and 5.5 g kg−1 fish fat could be used in diets for growing-finishing pigs without adverse effects. Key words: Fish silage, fish fat, growing-finishing pigs, growth performance, carcass characteristics, sensory quality
