A total of 140 growing pigs [Duroc × (Yorkshire × Landrace)] with an average body weight of 24.10 ± 1.66 kg were used in a 6 wk trial to determine the effect of dietary protease supplementation to ...

A total of 105 finishing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 51.0 ± 3.33 kg were used in a 10 wk trial to evaluate the effect of a protected blend of organic acids ...

An experiment was conducted to assess effects of Enterococcus faecium and a blend of organic acids (OAs) and medium-chain fatty acids (MCFAs) in finishing pigs. A total of 120 pigs [Duroc × (Yorkshire × Landrace); 51.04 ± 1.82 kg] were randomly assigned to five dietary treatments: CON, basal diet; BOM1, CON + 500 mg kg−1 blend of OAs and MCFAs; BOM2, CON + 1000 mg kg−1 blend of OAs and MCFAs; EBOM1, BOM1 + 20 mg kg−1 E. faecium; EBOM2, BOM2 + 20 mg kg−1 E. faecium. Pigs fed EBOM1 and EBOM2 diets had higher average daily gain and average daily feed intake (during days 36–70 and days 1–70) and greater digestibility of dry matter (days 35 and 70) compared with those fed BOM1 and BOM2 diets (P 0.05). In conclusion, supplementation with the combination of E. faecium and a blend of OAs and MCFAs was more effective in improving growth performance and nutrient digestibility than supplementation with blend of OAs and MCFAs alone in finishing pigs.

A total of 180 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an average body weight of 22.61 ± 1.23 kg were used in an 18 wk study to determine the effect of protease and bromelain in low-protein diets in grower–finisher pigs. Dietary treatments included: T1, basal diet treatment; T2, low-protein treatment; T3 (T2 + 0.2 g kg−1 protease); and T4 (T2 + 0.3 g kg−1 bromelain). Pigs fed protease- and bromelain-supplemented diets increased average daily gain and gain to feed ratio at week 18, dry matter and nitrogen digestibility at week 6, as well as energy digestibility at week 12, compared with low-protein diet (P 3) and hydrogen sulfide (H2S) emission was observed in pigs fed the dietary protease and bromelain supplementation at the 6th wk (P 3 and H2S in growing–finishing pigs.

A total of 480 one-day-old male Ross 308 broilers with an average initial body weight (BW) of 42 ± 1 g was randomly divided into four treatments (8 replicates/treatment, 15 birds/replicate) by their BW to evaluate the influence of a cocktail of protease and xylanase in different energy density of corn- and soybean-meal-based diet on broilers. This experiment lasted for 35 d and there were two phases; starter (1–18 d) and finisher (19–35 d). The experiment was a 2 × 2 factorial arrangement with two levels of metabolizable energy and the cocktail enzyme with 200 mg of protease kg−1 diet and 100 FXU xylanase kg−1 diet. Both high-nutrient density and cocktail enzyme supplementation increased (P 3) and hydrogen sulphide (H2S) emission. In conclusion, dietary supplementation of the cocktail enzyme component improved BWG, N retention, and reduced excreta noxious gas emission in broilers.

This study was conducted to evaluate the effect of Enterococcus faecium (EF) and endo-1,4-β-xylanase (XY) in finishing pigs. The pigs were randomly divided into four treatments with eight replicati...
