Main Effects

Abstract A total of 360 pigs (DNA 200′400, initially 5.0 kg) were used in a 45-d growth trial to determine the effects of fiber source and crude protein (CP) level in diets without pharmacological levels of ZnO on nursery pig growth performance and fecal dry matter (DM). Pigs were randomly assigned to 1 of 8 treatments with 5 pigs/pen and 9 pens/treatment. Treatments were arranged in a 2×4 factorial with main effects of CP (21 or 18%) and fiber source [none, coarse wheat bran (CWB), oat hulls, or cellulose (Arbocel, J. Rettenmaier USA, Schoolcraft, MI)]. Fiber source was added to equalize the level of insoluble fiber contributed from 4% CWB, resulting in the addition of 1.85% oat hulls or 1.55% cellulose. Diets were fed in two phases (d 0 to 10 and 10 to 24) followed by a common diet (d 24 to 45). The 21% CP diets contained 1.40% SID Lys in phase 1 and 1.35% SID Lys in phase 2. Treatment diets were formulated to a maximum SID Lys:digestible CP level of 6.35%, thus SID Lys decreased in the 18% CP (1.25% SID Lys) diets. Data were analyzed using the lmer function in R. No fiber source × CP level interactions (P >0.05) were observed. Decreasing dietary CP decreased (P = 0.05) ADG, G:F, and d 24 BW. Overall, ADG and d 45 BW decreased (P < 0.05) for pigs fed 18% CP diets. No main effects of fiber source were observed for growth performance throughout the study. Fecal DM increased (P < 0.05) for pigs fed added cellulose compared to pigs fed no fiber or CWB in the experimental period. In conclusion, reducing dietary CP decreased growth performance and the inclusion of cellulose improved fecal DM of nursery pigs.

Abstract A total of 2,304 newly weaned pigs (5.8±0.06 Kg BW, ~21-day old, DNA Genetics) were used in a RCBD to evaluate the effect of a direct-fed microbial (DFM) program on pig performance and survivability, under commercial pig production. Pigs were housed in 2 barns (blocking factor) with 36 pens each (32 pigs/pen, mixed-sex), and pens randomized to treatments: Control or DFM program (36 pens/treatment). The program consisted of a DFM (blend 1) delivered through drinking water (1.32x108 CFU/pig/day) from day 0 to 7, followed by another DFM (blend 2) in feed (1.5x105 CFU/g of feed) from day 7 through 49. Those DFM consisted of spore-forming Bacillus sp. selected to inhibit enterotoxigenic E. coli growth (blend 1) and reduce local inflammation (blend 2). The feeding program included phases 1 and 2 (7 days each) in pellet, and phases 3 (11 days) and 4 (24 days) in meal. Phase 1 feeds included antibiotics Chlortetracycline and Tiamulin; both phase 4 feeds included Carbadox. A severe diarrhea outbreak was observed in week 3; antibiotic therapy (Neomycin, Sulfadiazine or Trimethoprim) throughout drinking water was used in both treatments alike between days 19 and 28. Pig and feed weight were recorded by pen; ADG and ADFI were calculated on pig-days. Pigs removed included mortality and those ill, nonresponsive to antibiotics. Performance data were analyzed by ANOVA, using the GLM procedure. Pigs removed did not follow normal distribution and was analyzed using a parametric survival option with days as time variable (JMP v14.2.0). No differences were detected through day 25. Pigs in DFM consumed less feed (923 vs. 951 g/d; SEM=10.33; P=0.05) and were more efficient (0.61 vs. 0.59 kg/kg; SEM=0.004; P< 0.05) from days 25 to 49. Total pigs removed were reduced (P< 0.05) by 23% in DFM vs. Control (Table 1). In conclusion, the DFM program improved nursery pig survivability and late performance, under commercial pig production that included a diarrhea outbreak and antibiotic therapy.

Abstract Pharmacological concentrations of zinc (Zn, 2000-3000 ppm) are commonly fed to nursery pigs. However, diet manufacturing errors can result in supra-pharmacological concentrations of Zn (>4000 ppm) being fed. Clinical and phenotypic data reflective of Zn associated morbidity in modern genotype pigs are poorly defined. Therefore, the study objective was to characterize the effect of dietary Zn overload on nursery pig performance, body mineral concentrations and pathologic changes. Fifty-five 21 d old weaned pigs (4.50 ± 0.2 kg BW) were randomly assigned to one of five Zn diet treatments for 21 d. Diets included: 1) Control no additional Zn (NC), 2) 6000 ppm Zn for 21 d (Zn6), 3) 6000 ppm Zn for 7 d plus 4000 ppm Zn for 14 d (Zn64), 4) 3000 ppm Zn for 7 d and no additional Zn for 14 d (Zn3), and 5) 3000 ppm Zn for 7 d plus 2000 ppm for 14 d (Zn32). All pigs were bled and weighed at d 0, 7 and 21, and ADFI and G:F were determined for the overall 21 d test period. Thereafter, all pigs were necropsied for histopathology and serum, tissue and feed trace mineral concentrations were determined. Data were analyzed by one-way ANOVA with Tukey-Kramer adjustment in JMP. Overall pig ADG, ADFI and G:F was not statistically different between treatments. Feeding greater than 6000 ppm Zn increased pancreatic Zn concentrations compared to other groups (P < 0.001), and pancreatic apoptosis was more frequent in pigs fed supra-pharmacological levels of Zn (P < 0.0001). Hepatic and serum Zn levels were highest in diet 2 and 3 pigs compared to the other diets (P < 0.0001 and P = 0.0003 respectively) and only pigs from these treatments had serum Zn >2.0 ppm or hepatic Zn >500 ppm. Accordingly, these mineral levels should warrant further feed analysis if expected inclusion rates are 3,000 ppm Zn or less.

Abstract The objective was to evaluate the independent and additive effects of Cordyceps mushroom powder and carbadox to pharmacological copper+zinc in nursery pig diets. Two hundred-ten crossbred weanling pigs [(Duroc × (York × Landrace)] avg. 19 d of age and 5.8 kg were used in a 33 day growth trial. Pigs were alloted by weight, sex, ancestry, and assigned to body weight (BW) blocks. Within BW blocks, sex ratios were constant in each pen. Pen was the experimental unit and growth performance was analyzed using BW, ADG, ADFI, and G:F. There were 7 pigs/pen and 6 pens/treatment. Treatments were: 1) a negative diet (NC); 2) positive control (PC; Carbadox, 55 ppm); 3) NC+300 ppm Cordyceps mushroom powder (NC+MP); 4) PC +300 ppm mushroom(PC+MP); 5) supplemental copper sulfate (125 ppm) and zinc oxide (3000 ppm d 0-7, 2000 ppm d 7-35), CuZn. Dietary treatments were fed in a four-phase feeding program (d0-7, d7-14, d14-21, and d21-33). There were no interactions between MP and Carbadox at any time point (P > 0.10). Pigs fed the PC, PC+MP and CuZn treatment had increased BW (P < 0.05), ADG (P < 0.05), ADFI (P < 0.10) and G:F (P < 0.05) over the NC at the end of phases 1, 2, and 3, with no main effect of MP treatment. During Phase 4, pigs fed MP, PC, and CuZn diets all had increased ADG (P < 0.05; 431, 477, 455, 505, 486 g/d, diet 1-5, respectively) and ADFI (P < 0.05) over the NC fed pigs. Overall, d0-33, PC diets and CuZn supplemented pigs had increased ADG (P < 0.05) and ADFI (P < 0.05), with pigs fed MP tending to have increased ADFI (P < 0.08) over NC fed pigs. Feeding nursery pigs pharmacological levels of Cu+Zn and carbadox have economical value to increase nursery pig performance with MP may increase pig ADFI and final BW through potentially complimentary modes of action.

Abstract Two 47-d experiments were conducted with 21-d-old weaned pigs (PIC 1050, initially 6.1 kg) to determine the effects of feeding low or high doses of chlortetracycline (CTC) and antibiotic alternatives (Cu, Zn, and essential oil [EO]), alone or in combination, on growth performance. On d 5 postweaning, pens of 5 pigs were allotted to diet treatments with 8 (exp. 1) or 7 (exp. 2) replicate pens per treatment. In exp. 1, treatments were fed from d 5 to 26 postweaning and arranged in a 2 × 3 factorial with main effects of added ZnO (0 vs. 2,500 ppm of Zn) and CTC (0, 55, or 441 ppm). In exp. 2, treatments were fed from d 5 to 33 and structured in a (2 × 2 × 2) + 2 factorial with main effects of added CuSO4 (0 vs. 125 ppm Cu), added ZnO (0 vs. 3,000 ppm Zn from d 5 to 12 and 2,000 ppm Zn from d 12 to 33), and Regano EX (0 vs. 0.1% Regano EX containing 5% Origanum oil). The 2 additional treatments were subtherapeutic (55 ppm) and therapeutic (441 ppm) levels of CTC. Following the treatment period, a common diet without antimicrobial was fed until d 47. All diets contained 16.5 ppm Cu and 110 ppm Zn from the trace mineral premix. In exp. 1, no ZnO × CTC interactions were observed. Feeding ZnO increased (P &lt; 0.05) ADG, ADFI, and BW during the treatment period and increased (P &lt; 0.05) ADG and ADFI overall (d 5 to 47). Pigs fed CTC had increased (linear, P &lt; 0.05) ADG, ADFI, and BW during the treatment period and had marginally significant increases (linear, P &lt; 0.10) in overall ADG and ADFI, but overall G:F tended (quadratic, P = 0.070) to increase then decrease as CTC increased. During the treatment period in exp. 2, EO did not affect ADG or ADFI, whereas pharmacological levels of Cu, Zn, and CTC increased (P &lt; 0.05) ADG with coinciding increases (P = 0.055, 0.006, and linear 0.079, respectively) in ADFI. Copper, Zn, and CTC did not affect G:F. EO decreased (P = 0.009) G:F. Diet treatments had minimal carryover effects on subsequent nursery pig growth performance. Overall from d 5 to 47, Cu increased (P = 0.018) ADG, Zn increased (P &lt; 0.05) ADG and ADFI, and EO tended to decrease (P = 0.086) G:F. In conclusion, increased dietary Cu, Zn, or CTC improved weanling pig performance while EO elicited no growth benefits. The benefits of added Zn from ZnO and CTC were additive and could be included together in diets to maximize growth performance of weaned pigs.

Abstract A total of 320 barrows (DNA 200×400, initially 11.3 ± 0.65 kg BW) were used in a 21-d growth trial evaluating the effects of feeding Trp biomass (CJ America-Bio, Downers Grove, IL) as a source of Trp on nursery pig performance. Pigs were weaned at approximately 21 d of age, placed in pens based on initial BW, and fed a common diet. On d 21 after weaning, pigs were weighed and pens were allotted to 1 of 4 dietary treatments with 5 pigs/pen and 16 replicates/treatment. Dietary treatments included a negative control (16% SID Trp:Lys), positive control (21% SID Trp:Lys from crystalline L-Trp), or diets containing Trp biomass to provide 21 or 23.5% SID Trp:Lys (included at 0.104 or 0.156% of the diet, respectively). Diets were corn-soybean meal based and contained 1.25% SID Lys with other AA set to meet or exceed NRC (2012) requirement estimates. The Trp biomass contained 69% Trp. Growth data were analyzed as a randomized complete block design using PROC GLIMMIX of SAS with pen as the experimental unit. Overall (d 0 to 21) pigs fed 21% Trp from L-Trp or Trp biomass had increased (P < 0.05) ADG compared to the control, with pigs fed the 23.5% SID Trp biomass intermediate. Pigs fed the 21% Trp from Trp biomass had improved (P < 0.05) G:F compared to the control with others intermediate. In conclusion, Trp biomass is a viable alternative to crystalline Trp, but further evaluation at higher inclusion levels is needed.

Abstract Automatic Ultrafiltration Portable is used to produce clean and ready-to-consume water from a water source in peatlands. Water is one of the factors that really supports the community, including the process of cooking, bathing, washing, and toilet (MCK). The villagers of Jambu Burung and Jambu Raya at the new lucky sub-district use rainwater as drinking water and river water and pond water (well) to meet their daily needs, one of which is in the consumption sector. However, the water in the river that is used by the community is cloudy and smelly, so it is dangerous to health if it is continuously consumed by humans. The quality of clean water is very influential on the results of the quality of human life. The use of river and well water by the guava and guava community has been going on for years, so it is estimated that there are no other alternatives to get proper clean water. So, Automatic Ultrafiltration Portable is one solution to solve this problem. This tool is made based on the need for a portable tool because the size is 40x80x30 cm, practical, and economical, but has good performance (discharge 1 - 5 liters / minute) and can be increased. .

Abstract Weanling pigs (n = 360, DNA 200 × 400, initially 5.90 kg) were used to evaluate pharmacological levels of Zn (ZnO), diet acidification (sodium diformate; Addcon, Bitterfeld-Wolfen, Germany), and crude protein (18 or 21% CP) on pig performance. At weaning, pigs were assigned to treatments with 5 pigs/pen and 9 pens/treatment. Treatments were arranged in a 2×2×2 factorial with main effects of Zn (110 mg/kg from d 0 to 21 or 3,000 mg/kg from d 0 to 7, and 2,000 mg/kg from d 7 to 21), diet acidification (without or with 1.2% sodium diformate), and dietary CP (21 or 18%). The 21% CP diets were formulated to 1.40 and 1.35% SID Lys in phase 1 and 2, respectively, and 18% CP diets were formulated to 1.20% SID Lys. Experimental diets were fed from d 0 to 21 with a common diet from d 21 to 42. Fecal samples were collected weekly to determine fecal dry matter (DM). Data were analyzed using R Studio as a RCBD. From d 0 to 21, ADG and G:F increased (P &lt; 0.05) for pigs fed pharmacological Zn, and sodium diformate. Overall, ADG tended (P ≤ 0.069) to increase for pigs fed added Zn or sodium diformate. Pigs fed 21% CP had increased (P &lt; 0.05) ADG and G:F from d 0 to 21 and overall G:F compared with those fed 18% CP. Feeding 18% CP diets increased fecal dry matter on d 7 when pharmacological Zn and sodium diformate were not in the diet (Zn×acidifier×CP interaction, P &lt; 0.05). From d 21 to 42, there was no evidence of difference in growth performance. In conclusion, reducing CP without acidification increased fecal DM when pharmacological Zn were not in the diet, but had little effect when it was in the diet. Adding sodium diformate and pharmacological Zn independently improved nursery pig growth performance.

Occurrence of perchlorate (ClO4−), chlorate (ClO3−) and bromate (BrO3−) in public drinking, open well and surface water sources at 20 locations in the South-West coastal state of Kerala (India) is reported. The analysis was performed by high performance liquid chromatography interfaced with tandem mass spectrometry (HPLC–MS/MS). Irrespective of water source (public tap water, open well water and surface water) all the analyzed samples contained high levels of ClO4−, indicating its contamination throughout the region. The highest ClO4− level found was 91.4 μg/L, which is 3.7 times higher than US EPA recommendations. ClO3− and BrO3− were also detected in the samples, with highest concentrations of 177 and 5.34 μg/L respectively in tap water samples. Regression analysis showed moderate positive correlation between ClO4− and bromide (Br−) in tap water (r2=0.659) and open well water (r2=0.485) samples, respectively. Similar correlation was also observed between ClO4− and Cl− (r2=0.591) concentrations in well water samples, indicating sea water could be one of the probable sources in addition to ClO4− manufacturing in the area. This is the first report of high levels of ClO4− and ClO3− and detectable BrO3− in water samples from anywhere in India.

Abstract Trials suggest short and medium chain fatty acids can be used as alternatives for ZnO; however, US studies are limited. Therefore, the objective of this study was to evaluate the effects of a short and medium chain fatty acid product (Monomix, Quality Technology International, Inc., Elgin, IL) added alone or in combination with pharmacological levels of ZnO on nursery pig performance. A total of 354 pigs (DNA 200×400, initial BW=5.9 kg) were randomized to pens (5 pigs/pen) and pens were allotted to 1 of 4 treatments with 18 replicates/treatment. Treatments were arranged in a 2×2 factorial with main effects of added ZnO (0 vs. 3,000/2,000/0 ppm of Zn in phases 1, 2, and 3 respectively) and Monomix (0 vs. 0.4% in phases 1, 2, and 3). Treatment diets were formulated in three phases fed from d 0 to 7, 7 to 18, and 18 to 35 post-weaning with all diets containing 110 ppm Zn from the trace mineral premix. Data were analyzed as completely randomized design using the PROC GLIMMIX procedure of SAS with pen as the experimental unit. No ZnO × Monomix interactions (P=0.399) were observed. Feeding Monomix decreased ADFI (P=0.002) and ADG (P=0.012) from d 0 to 7, resulting in decreased d 7 BW (P=0.015) but there was no evidence for other differences. Feeding ZnO from d 0 to 7 and 7 to 18,increased ADG (P&lt; 0.001), ADFI, and BW, and improved G:F. Overall from d 0 to 35, pigs fed diets with added ZnO in phases 1 and 2 had increased (P&lt; 0.05) ADG, ADFI, and d 35 BW, with no evidence for differences in performance in pigs fed diets with Monomix. The addition of Monomix failed to improve pig performance, whereas pharmacological levels of ZnO improved ADG and ADFI.
