Abstract

Abstract: One hundred Landrace x Yorkshire barrows (BW Mean 9.49 kg, SD 1.18 kg) were used in a thirty-day 2 x 2 RCBD trial to study the effects of soybean meal (SBM) and β-mannanase (Hemicell XT) on major serum biochemical constituents. Treatments were SBM (220 and 370 g/kg, making dietary soluble β-mannan to 2420 and 4070 ppm, respectively) and β-mannanase (0 and 200 mg/kg). Diets were isocaloric (3200 kcal/kg ME) and equal in SID Lys (12.5 g/kg). On Day 30, six pigs per treatment were sacrificed for blood from mesenteric vein, portal vein and carotid artery for the measurements. Data were analyzed with GLM of SPSS. In mesenteric vein, SBM decreased total protein (TP) (P=0.04), creatinine (P<0.05), calcium (P=0.01) and phosphorus (P=0.03), and increased lactate dehydrogenase (LDH) (P=0.02). B-mannanase increase albumin (P<0.01), creatinine (P<0.01) and calcium (P<0.02), and decreased blood urea nitrogen (BUN) (P<0.01), alanine aminotransferase (ALT) (P<0.01) and glutamic oxaloacetic transaminase (GOT) (P<0.01). SBM x β-mannanase affected albumin (P<0.01), creatinine (P=0.03), calcium (P<0.01), LDH and GOT (P<0.05). B-mannanase improved TP, albumin, BUN, creatinine, LDH, GOT, calcium and phosphorus in high SBM diet close to the levels of low soybean meal diets. In portal vein, SBM increased GOT (P=0.01) and β-mannanase decreased BUN (P=0.03). SBM x β-mannanase affected ALT (P<0.05) and GOT (P<0.01). B-mannanase restored ALT and GOT in high SBM diet to the levels of low soybean meal diets. In carotid artery, SBM increased TP (P<0.05), albumin (P<0.01), BUN (P<0.01), LDH (P<0.05) and GOT (P<0.01), and decreased alkaline phosphatase (ALP) (P<0.01). SBM x β-mannanase affected LDH (P=0.03) and GOT (P<0.01). B-mannanase restored LDH and GOT in high SBM diet to the levels of low soybean meal diets. SBM and β-mannanase appeared to counteract on nitrogen and mineral metabolism and, as indicated by serum enzyme activities, on body cavity tissue injuries.
