Abstract Two experiments were conducted to investigate the effects of a combined α-galactosidase and xylanase preparation on nutrients digestibility and growth performance in broiler chickens. Experiment 1 had 240 broilers allocated to 3 treatments with the dietary supplementation of 0, 300 and 500 g/t of the enzyme combination. Diet and amino acid (AA) digestibility were assessed. Experiment 2 was a 2 × 3 (enzyme × diet) factorial arrangement with 10 replicates of 12 male broilers per replicate. Diets were based on corn-Soybean meal (SBM) diet and had 3 nutritional levels (normal, 2% apparent metabolizable energy (AME) and crude protein (CP) reduction, and 4% AME and CP reduction). Each of these diets was fed with or without enzyme supplementation. Growth performance, chyme viscosity, nutrients digestibility, and endogenous enzymes activity were assessed. In experiment 1, enzyme supplementation improved the digestibility of Ca (P = 0.025) and ileal digestibility of total AA, Pro, Alu, Ile, Lys, His, Thr, Glu, Val, Leu, Tyr and Phe (P < 0.05), and also tended to increase the AME of diets (P < 0.10). In experiment 2, broilers fed the corn-SBM diet with 4% nutrient reduction had better growth performance (P < 0.05), jejunal digesta viscosity at 42 days (P < 0.01), and lower digestibility of gross energy (GE) (P < 0.05) when compared to those fed the normal nutrient diet. Enzyme inclusion increased digestibility of CP (P = 0.044), GE (P = 0.009), raffinose (P < 0.001) and stachyose (P < 0.001), improved average daily gain (P = 0.031), and reduced jejunal digesta viscosity at 42 days (P = 0.011). Besides, similar improvements trend in amylase, trypsin, sucrase, and maltase activity with enzyme inclusion were observed as with energy. These data support that the enzyme supplementation increased nutrients and ileal amino acid digestibility, improved performance and endogenous enzymes activity.

Abstract Previously, we reported that supplementing a water soluble zinc via drinking water (0 to 80 mg/L) to nursery pigs improved ADG and G:F. To evaluate the efficacy of higher titrated levels of this water soluble zinc amino acid complex (ProPath®Zn LQ, Zinpro Corporation, Eden Prairie, MN) on growth performance, 280 crossbred pigs (5.5 kg BW; 19 d of age) were randomly allotted to four water treatments (7 pens/treatment; 10 pigs/pen). The water treatments were 0, 40, 80 and 160 mg Zn/L of water. Pigs were fed in 4 dietary phases with complex, nutrient-dense, corn-soybean meal-based diets: Phase 1 and 2 (2,500 and 1,750 mg Zn as ZnO/kg; d 1–7 and 7–14, respectively) and Phase 3 and 4 (200 mg Cu as CuSO4/kg; d 14–23 and 23–42, respectively). Pigs and feeders were weighed weekly to determine ADG, ADFI, and G:F. Water meters were used to record and calculate water disappearance and zinc intake. Data were analyzed as a randomized complete block design. Orthogonal polynomial contrasts were used to determine linear and curvilinear effects. Water and total zinc intake increased linearly (P < 0.001) with increasing water zinc concentration. From d 0–14 when high dietary zinc was fed, there were no differences (P > 0.10) in ADG, ADFI, or G:F. However, from d 14–42 when basal levels of zinc were fed, quadratic improvements in ADG (0.545, 0.561, 0.578, 0.546 kg; P < 0.05) and G:F (0.686, 0.706, 0.723, 0.702; P < 0.01) were observed with increasing zinc via water. Similarly for d 0–42, ADG (0.435, 0.440, 0.454; 0.434 kg; P = 0.07), G:F (0.726, 0.740, 0.763, 0.749; P = 0.05) and average ending wt (23.73, 23.97, 24.55, 23.70 kg; P = 0.07) improved quadratically with increasing zinc. In conclusion, supplementing ProPath®Zn LQ via water resulted in improvements in ADG and G:F for nursery pigs.
