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.

There have been a number of reports that voluntary feed intake (VFI) of modern pig genotypes may be the limitation to their growth performance. It has been suggested that selection for leanness (Fowler et al. 1976) and breeding for faster growth may have reduced appetite.In addition there is only limited information about the effect on VFI, performance and carcass characteristics of pigs fed ad libitum to liveweights greater than 100kg. A study was therefore undertaken to compare VFI and energy intake of improved genotypes with predicted intakes based on earlier genotypes (ARC, 1981). The associated effects on performance and carcass characteristics at heavier slaughter weights were also studied.

Abstract Two experiments were conducted to compare the standardized ileal digestibility (SID) of AA by growing pigs in European distillers dried grains with solubles (DDGS) produced from wheat, maize, or wheat–maize mixtures and to test the effect of increasing the inclusion levels of wheat DDGS on growth performance of growing-finishing pigs fed diets balanced for NE and SID Lys. In Exp. 1, 12 barrows (initial BW: 23.0 ± 2.2 kg) were surgically equipped with a T-cannula in the distal ileum and randomly allotted to a replicated 6 × 6 Latin square design with six diets and six periods. Five sources of European DDGS were used: wheat DDGS from 2011, wheat DDGS from 2012, wheat-80 DDGS (80% wheat and 20% maize), wheat-70 DDGS (70% wheat and 30% maize), and maize DDGS. Each diet contained one source of DDGS as the sole source of AA and an N-free diet was used to determine basal endogenous losses of AA. Results indicated that the SID of CP was greater (P &lt; 0.05) in maize DDGS compared with wheat DDGS from 2011, wheat DDGS from 2012, and wheat-70 DDGS. The SID of all indispensable AA except Trp was also greater (P &lt; 0.05) in maize DDGS compared with all other DDGS sources used in this experiment. For Trp, the SID in wheat-80 DDGS, wheat DDGS from 2011, and wheat DDGS from 2012 were not different from maize DDGS, but were greater (P &lt; 0.05) than in wheat-70 DDGS. The SID for all indispensable AA except Ile and Trp in wheat-70 DDGS were not different from the values calculated for wheat DDGS from 2011 and wheat DDGS from 2012, and no differences between SID values for AA in wheat DDGS from 2011 and wheat DDGS from 2012 were observed. In Exp. 2, 36 growing pigs (initial BW: 38.3 ± 1.97 kg) were randomly allotted to one of four dietary treatments (one pig/pen and nine replicate pigs/treatment) in a 2-phase feeding program (35 to 65, and 35 to 105 kg BW). The four dietary treatments included diets containing 0%, 10%, 20%, or 30% wheat DDGS. Results indicated that there was no effect of wheat DDGS on pig growth performance or carcass quality. However, addition of wheat DDGS increased linearly (P &lt; 0.015) the indole concentration in the carcasses of the pigs. In conclusion, the SID of AA in maize DDGS produced in Europe is greater than in European wheat DDGS and DDGS produced from mixtures of wheat and maize, but inclusion of 30% wheat DDGS in diets fed to growing-finishing pigs did not affect growth performance or carcass quality.

Abstract The present study was undertaken to determine the effects of different flavours (apple and anise) on growth performance, nutrient digestibility, blood profiles and carcass quality in growing-finishing pigs. A total of 96 pigs [(Landrace × Yorkshire) × Duroc] with an average initial BW of 28.2 ± 0.7 kg were assigned to 1 of 3 dietary treatments. The treatments consisted of (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavour; (3) ANF, basal diet + 0.05% anise flavour. There were 8 replications (pens) per treatment and 4 pigs per pen (2 barrows and 2 gilts). The flavour was added at the expense of corn (0.05%). The experiment lasted for 15 wks. The data were analyzed by ANOVA using the GLM procedure of SAS (SAS Institute Inc., Cary, NC, USA) with the pen as the experimental unit. Variability in the data was expressed as the standard error of means (SEM) and a probability level of p &lt; 0.05 was considered to be statistically significant. During week 0-5, pigs fed ANF diets had greater (p &lt; 0.05) ADG and ADFI than those fed CON and APF diets. Dietary ANF treatment increased (p &lt; 0.05) ADG during 0-15 week compared with CON treatment (Table 1). At the end of 5 week, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p &lt; 0.05) compared with that in CON treatment (Table 1). There were no differences (p &gt; 0.05) in the red blood cell and white blood cell counts or lymphocyte percentage among treatments. In conclusion, anise flavour supplementation could lead to significant improvement in ADG and N digestibility in growing pigs and the ADG was also higher in finishing pigs fed anise flavour supplemented diet. Furthermore, apple flavour supplementation had minor effect on growth performance, nutrient digestibility, blood profiles or carcass quality in finishing pigs.
