PSXVI-42 Dietary soybean meal level and β-mannanase supplementation affected serum biochemical constituents in nursery pigs.

Ruminal acidosis is an important clinical emergency in small ruminants. In this study, eight healthy farm goats and 24 goats presented at TVCC of the college of Veterinary Sciences and A.H., Anand with clinical signs of ruminal acidosis and having rumen liquor pH below 6 were examined for alterations in the ruminal fluid and serum biochemical parameters. Among various rumen fluid parameters evaluated, the mean values of rumen fluid pH decreased significantly (4.71±0.11 vs. 6.90±0.10), while sediment activity time (46.67±1.20 vs. 24.50±0.78 min) and methylene blue reduction time (29.50±0.73 vs. 10.03±0.27 min) increased significantly in acidotic goats. The normal greenish, aromatic viscous color, odour and consistency of rumen fluid of healthy goats also changed to milky grey/creamy, sour/pungent watery in acidotic goats. The rumen protozoal activity decreased to nil in acidotic goats as compared to the healthy goats. Among various serum biochemical constituents, the mean values of glucose (92.43±1.37 vs. 74.13±1.83 mg/dl), BUN (26.49±0.47 vs. 22.63±1.19 mg/dl), serum creatinine (01.01±0.02 vs. 00.83±0.02 mg/dl) and albumin (03.22±0.03 vs. 03.05±0.05 g/dl), ALT (56.75±1.55 vs. 27.88±1.14 IU/L) and AST (93.25±1.82 vs. 54.00±1.75 IU/L), increased significantly, while there was significant decrease in serum calcium (09.09±0.14 vs. 10.29±0.08 mg/dl) in acidotic goats. The mean values of alkaline phosphatase (IU/L) in acidotic goats increased non-significantly from the base values of healthy goats.

Abstract Feed enzymes may ameliorate reduced nutrient and energy digestibility in nursery pigs. The objective was to test effects of super-dosing phytase and fiber-degrading enzymes on digestibility of DM, GE, CP, AA, and Ca. We tested supplementing a super dose (added 1,500 FYT/kg) of phytase (Ronozyme Hi-Phos) with or without carbohydrase cocktail that contained 85 FXU β-xylanase/kg, 587 U/g endo-1,4-β-glucanase, 513 U/g endo-1,3(4)-β-glucanase, 15,000 U/g hemicellulases, and 3,000 U/g pectinases in corn-soybean meal diets in a 2 × 2 factorial arrangement. Diets included 68% corn, 17% SBM, and a basal level of 500 FTU/kg of phytase, and were formulated to contain 2.50 Mcal/kg NE and 5.10 gSID Lys/Mcal NE. Eight ileal-cannulated nursery pigs (initial BW 10 kg) were fed 4 diets at 3.0 × maintenance DE (110 kcal per kg of BW0.75) for four 9-day periods in a double 4 × 4 Latin square. Apparent hindgut fermentation (AHF) was calculated as apparent total tract digestibility (ATTD) minus apparent ileal digestibility (AID). Interactions between super-dosing phytase and carbohydrase cocktail were observed. Supplementing either carbohydrase cocktail or super dose phytase, but not their combination, increased (P < 0.05) diet AID of DM, GE, CP, and most AA by 4–5%-units. Supplementing super dose phytase increased (P < 0.05) AID of P by 16%-units and ATTD of P by 10%-units. Supplementing super dose phytase or carbohydrase cocktail did not affect AID of Ca and ATTD of GE, CP, and Ca, and diet DE value. Supplementing carbohydrase cocktail without super dose phytase decreased (P < 0.05) diet AHF of DM, GE, and CP. In conclusion, dietary inclusion of super dose phytase or carbohydrase cocktail increased ileal digestibility of nutrients in nursery pigs, and thereby reduced protein entering the large intestine. Additive or synergistic effects of carbohydrase cocktail and super dose phytase were not detected.

Main Effects

Abstract Four experiments were conducted to determine the effects of increasing soybean meal (SBM) in diets with or without 25% DDGS on growth performance of nursery pigs. Treatments were arranged in a 2 × 3 factorial with main effects of SBM (27.5, 32.5, or 37.5%) and DDGS (0 or 25%). A total of 296, 2,502, 4,118, and 711 pigs, initially 10.6, 11.7, 12.5, and 12.3 kg, were used and there were 10, 16, 13, and 12 replicates per treatment in Exp. 1, 2, 3, and 4, respectively. Experimental diets were fed for 21 d. Pigs were weighed and feed disappearance measured to calculate ADG, ADFI, G:F, and caloric efficiency (CE). Data were analyzed using the GLIMMIX procedure of SAS with block as random effect and treatment as fixed effect. The average cull rate was 0.7, 0.5, 0.2, and 0% and the mortality rate was 0.7, 0.3, 0.4, and 0% in Exp. 1 to 4, respectively. There were interactions (P ≤ 0.039) between SBM and DDGS for G:F and CE in Exp. 2 and for ADG and ADFI in Exp. 3. These were mostly driven by increasing SBM negatively affecting performance in a greater magnitude when diets contained DDGS compared to diets without DDGS. The main effects of DDGS and SBM were more consistent across experiments. Pigs fed diets with 25% DDGS had decreased (P ≤ 0.001) ADG and ADFI in all experiments as well as poorer (P ≤ 0.028) G:F and CE except for Exp. 3. Feeding increasing amounts of SBM generally did not result in any major impact in ADG, but consistently improved (linear, P ≤ 0.078) G:F and CE across experiments. The mechanism for this response is unclear but could be driven by intrinsic components of SBM or underestimating the energy value of SBM.

Abstract The objectives were to determine the digestible energy and standardized ileal digestibility of amino acids (AA; Exp. 1) and to determine growth performance (Exp. 2) of 2 sources of dietary spray-dried plasma protein (SDPP) in nursery pigs. In Exp. 1, twelve nursery barrows (9.8 ± 0.9 kg) were assigned to a quadruplicated 3 × 2 Latin square design with 3 diets and 2 periods. Each period consisted of 5 days of adaptation, 2 days of fecal sampling, and 2 days of ileal collection. A basal diet was composed of corn, soybean meal, whey, and sucrose as the sole energy and AA sources. Experimental diets were prepared by replacing 15% of the energy and AA sources in the basal diet with SDPP 1 (manufactured in the USA; 78.2% crude protein and 4,862 kcal gross energy/kg as-is) or SDPP 2 (manufactured in Korea; 74.3% crude protein and 4,636 kcal gross energy/kg as-is). Spray-dried plasma protein 1 had greater digestible energy (P < 0.05), but less (P < 0.05) standardized ileal digestibility of Lys, Met, Trp, and Thr compared with SDPP 2. In Exp. 2, eighty-four nursery pigs (7.9 ± 0.7 kg) were allotted to 3 dietary treatments in a randomized complete block design with 7 replicate pens and 4 pigs per pen. Three corn-soybean meal-whey-based diets contained fish meal (6% and 3.5% for d 0 to 14 and d 14 to 28, respectively), SDPP 1 (4.5% and 2.7%), or SDPP 2 (5.0% and 3.0%) to maintain same energy and nutrient concentrations. During d 0 to 14 and overall period, pigs fed the diets containing SDPP gained more weight (P < 0.05) than those fed the fish meal diet with no difference between 2 SDPP sources. In conclusion, SDPP 1 contains greater digestible energy but less AA digestibility compared with SDPP 2. Growth-promoting effects of both SDPP sources in nursery diets have been clearly demonstrated in this work.

In Exp. 1, twelve nursery barrows (9.8 ± 0.9 kg) were assigned to a quadruplicated 3 × 2 Latin square design with 3 diets and 2 periods. Each period consisted of 5 days of adaptation, 2 days of fecal sampling, and 2 days of ileal collection. A basal diet was composed of corn, soybean meal, dried whey, and sucrose as the sole energy and AA sources. Experimental diets were prepared by replacing 15% of the energy and AA sources in the basal diet with SDPP 1 (manufactured in the US; 78.2% CP and 4,862 kcal GE/kg as-is) or SDPP 2 (manufactured in Korea; 74.3% CP and 4,636 kcal GE/kg as-is). Spray-dried plasma protein 1 had greater digestible energy (4,799 vs. 4,469 kcal/kg as-is; P < 0.05), but less (P < 0.05) standardized ileal digestibility of lysine, methionine, tryptophan, and threonine compared with SDPP 2. In Exp. 2, eighty-four nursery pigs (7.9 ± 0.7 kg) were allotted to 3 dietary treatments in a randomized complete block design with 7 replicate pens and 4 pigs per pen. Three corn-soybean meal-whey-based diets contained fish meal (6% and 3.5% for d 0 to 14 and d 14 to 28, respectively), SDPP 1 (4.5% and 2.7%), or SDPP 2 (5% and 3%) to maintain same energy and nutrient concentrations. During d 0 to 14 and overall period, pigs fed the diets containing SDPP gained more weight (P < 0.05) than those fed the fish meal diet with no difference between 2 sources of SDPP. Overall, 2 sources of SDPP have different energy concentrations and AA digestibility, but similar growth promoting effects in nursery pigs.

The effects of dietary replacements of fish meal with soybean meal on growth performance, heamatology and serum biochemistry in juvenile Labeo cubie were evaluated. Four hundred and fifty (450) apparently healthy juvenile Laboe cubie were distributed into one of fifteen 1000 L tanks divided into five groups and fed any of diets A (0% soybean meal); B (30% soybean meal); C (40% soybean meal); D (45% soybean meal) and diet E (75% soybean meal) for 56 days. At set time points day 7, 14, 28 and day 56, five fish were randomly selected per tank for growth assessments, heamatology and serum biochemical evaluations. Growth performance indices decreased significantly (p < 0.05) along the gradient of soybean meal inclusion and the duration of feeding. The erythrocytes count increased significantly (p < 0.05) at day 14 in fish fed soybean meal diets and decreased significantly (p < 0.05) beginning at day 28 in fish fed soybean meal-based diets. The haematocrit of fish fed diets D and E were significantly (p < 0.05) lower at day 28 compared to day 56. There were no significant variations in haemoglobin concentration and the leucocytes counts (p > 0.05). The proteins, blood glucose and the transaminases increased significantly (p < 0.05) along gradient of dietary inclusion and duration of feeding in the first 28 days while creatinine kinase activity, blood urea nitrogen and uric acid concentration remained significantly elevated (p < 0.05) in fish fed the soybean meal-based diets. The results of the study show juvenile L. cubie may tolerate up to 40% dietary inclusion of soybean meal as replacement for fish meal.

Abstract Two experiments were conducted to determine the effects of soybean meal (SBM) level in diets with or without distillers dried grains with solubles (DDGS) on growth performance of late nursery pigs. A total of 1,064 and 1,011 pigs (PIC 280×1050; initially 10.5 ± 0.36 and 10.9 ± 0.22 kg) were used in Exp. 1 and 2, respectively, with 21 to 27 pigs per pen. Pens were assigned to treatments in a randomized complete block design with 7 replicates per treatment per experiment. Treatments 1 to 3 were diets with 23% DDGS and 21, 27, or 35% SBM. Treatments 4 and 5 were corn-SBM diets with 27 or 35% SBM. Diets were balanced to 1.30% standardized ileal digestible lysine and 2,606 kcal of net energy/kg. Data were analyzed with the GLIMMIX procedure of SAS with pen as the experimental unit and block as random effect. There was no evidence for treatment × experiment interactions, thus data from both trials were combined. Feeding diets with 23% DDGS decreased (P = 0.033) ADFI and improved (P = 0.033) G:F compared to corn-SBM diets, which may indicate underestimation of DDGS net energy. When analyzed as a factorial with or without DDGS, pigs fed diets with 35% SBM had a tendency (P = 0.052) for increased ADG and improved (P = 0.001) G:F compared with diets with pigs fed 27% SBM. As SBM increased from 21 to 35% in diets with DDGS, ADG (linear, P = 0.001) and G:F (quadratic, P = 0.007) improved. In summary, feeding diets with increasing SBM improved growth performance in late nursery pigs.
