This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

A 6 wk trial was conducted to evaluate the effects of nucleotide supplementation in improving performance, nutrient digestibility, and immune blood profiles so as to reduce foot-and-mouth disease (FMD) vaccine stress in growing pigs. A total of 120 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 25.76 ± 1.83 kg were used. Pigs were allocated to one of three treatments (eight pens per treatment; three barrows and two gilts per pen) based on BW and sex. Pigs were injected with FMD vaccine at 84 d of age (2 wk after experiment started). Dietary treatments consisted of (1) CON: corn–soybean-meal-based diet, (2) NUC1: CON + 0.5% nucleotide, and (3) NUC2: CON + 1.0% nucleotide. In the current study, the growth performance of gain:feed ratio (G:F), the apparent total tract digestibility of dry matter and nitrogen was linearly (P < 0.05) increased with the increasing level of nucleotide. After injection, the concentration of cortisol and epinephrine was decreased (P < 0.05) linearly in nucleotide treatments. In conclusion, nucleotide supplementation to FMD vaccinated pigs showed positive effects on improving performance, immune system health, and reducing vaccine stress in growing pigs.
