The objectives were to determine effects of a hatchery byproduct mixture (HBM) on growth performance and to measure digestible energy concentrations in various HBM. In the growth performance experiment, 96 pigs (initial body weight = 9.6 ± 0.8 kg) were assigned to 4 dietary treatments in a randomized complete block design with 6 blocks. Each treatment consisted of 6 replicate pens with 4 pigs comprising 2 barrows and 2 gilts. Pigs were fed graded concentrations of HBM at 0%, 3.33%, 6.67%, and 10.00% for 14 days. In the energy digestibility experiment, 10 barrows (initial body weight = 11.5 ± 0.4 kg) were employed to determine digestible energy in HBM. A basal diet based on corn and soybean meal and 4 additional diets containing 25% of 4 different HBM were prepared. The marker-to-marker method was employed for total collection and the experimental design was a replicated 5 × 4 Latins square design. Growth performance was not compromised as the inclusion rate of HBM increased up to 10%. Digestible energy of HBM ranged from 2772 to 3887 kcal/kg as-is basis. In conclusion, HBM can be used in nursery pig diets and different energy values should be used for each HBM.

Lipid Supplement

Abstract The objective was to evaluate Yarrowia lipolytica (YL) as a lipid supplement fed to nursery pigs for the growth performance and apparent ileal digestibility (AID). Twenty-four pigs weaned at 21 d of age (12 barrows and 12 gilts with initial BW at 7.2 ± 0.6 kg) were allotted to 3 dietary treatments (n = 8) based on the randomized complete block design with sex and BW as blocks. The main effect was the dietary supplementation of YL (0, 1.5, and 3.0%, replacing poultry fat) with nutrients meeting or exceeding the requirements by NRC (2012) and fed to pigs for 21 d based on 2 phases. Feed intake and BW were recorded at d 0, 10, and 21 to calculate ADG, ADFI, and G:F. Fecal scores were recorded at every odd day from d 3 to 19. Pigs were euthanized on d 21 to collect ileal digesta for AID of nutrients in diets. Data were analyzed using Proc Mixed of SAS. There were no differences in growth performance among treatments. Whereas, pigs fed 0 and 1.5% YL had higher (P < 0.05) AID of DM (55.0 and 52.2% to 40.2%, respectively) and GE (62.1 and 60.6% to 49.8%, respectively) than pigs fed 3% YL. There were no differences in AID of DM and GE between the pigs fed 0% and 1.5% YL. In conclusion, 1.5% Yarrowia lipolytica could be supplemented in nursery pig diets reducing 0.8% of poultry fat without affecting growth performance and AID of DM and GE.

This study was conducted to evaluate the effects of dietary FVS supplementation on growth performance, nutrient digestibility, biochemical profile of serum and fecal short chain fatty acids (SCFAs) production in weaned piglets. In Exp.1, 150 weaned pigs (initial body weight: 6.89 ± 1.17 kg) were allotted to five dietary treatments. The treatment diets included a basal diet and four experimental diets supplemented with 2.5%, 5.0%, 7.5% and 10.0% FVS respectively. The animal trial lasted for 28 days. In Exp.2, 72 piglets (initial body weight: 8.20 ± 1.67 kg) were allotted to three dietary treatments. The treatment diets included a basal diet and two experimental diets supplemented with 1.5% and 3.0% FVS, respectively. The animal trial lasted for 56 days. The results showed that pigs fed dietary FVS with 3% or lower inclusion levels had no significant difference (p > 0.10) on growth performance compared with pigs fed the control diet during day 1–28 and day 1–56. Dietary FVS supplementation decreased the apparent total tract digestibility (ATTD) of nutrients on day 28, day 35 and day 56, but no significant changes (p > 0.05) of nutrient digestibility were observed on day 14. Although piglets fed diets with higher levels of FVS showed impaired growth performance and ATTD of nutrients, dietary FVS supplementation improved the fecal SCFA production, antioxidant capacity, interleukin-2 and growth hormone levels in serum, and reduced the harmful low-density lipoprotein levels in serum on day 56. In conclusion, as a promising alternative fibrous ingredient, FVS could be supplemented in diets of weaned piglets with a proportion under 3%.

This study was conducted to compare the effect of Colistin and Cap-Met supplementation in nursery pig diets on growth performance, fecal score, short chain fatty acids in the caecum and gut immunity. Seventy-two crossbred pigs (Duroc x Large White x Landrace; initial weight 6.76 ± 0.22 kg) were divided into 3 groups with 6 replications of 18 piglets each. There were 3 dietary treatments: 1) basal diet, 2) basal diet + Colistin 40 ppm and 3) basal diet + 0.2% Cap-Met. The supplementation of 0.2% Cap-Met improved FCR of piglets during 24-38 days of age. At 66 days of age, supplementing Colistin or Cap-Met increased the concentration of lactic acid in the caecum, while the IL-1 beta level in the jejunum declined. In conclusion, Cap-Met supplementation improved the FCR and showed positive immune and inflammatory responses of piglets.

Abstract This study investigated the interactive effects of Zn sources, Cu sources and phytase on growth performance in nursery pigs. A total of 288 weaning barrows (BW = 5.71 ± 0.81 kg), blocked by initial body weight, were randomly allotted to 1 of 8 dietary treatments, with 9 pens per treatment and 4 pigs per pen. The 8 dietary treatments were arranged in 2 × 2 × 2 factorial design, with 2 Zn sources [2000 ppm Zn from ZnO during phase 1 (d 1 to 14) and 2 (d 15 to 28), and 100 ppm Zn from ZnO during phase 3 (d 29 to 42); 100 ppm Zn from Zn methionine hydroxy analogue chelate (Zn-MHAC, MINTREX® Zn, Novus International Inc., St. Charles, MO) during phase 1 to 3], 2 Cu sources [150 ppm Cu from CuSO4 or Cu-MHAC (MINTREX® Cu) during phase 1, and 80 ppm Cu from CuSO4 or Cu-MHAC during phase 2 and 3], and 2 phytase inclusion levels (0, 500 FTU/kg). Results showed that there were no differences (P > 0.10) between ZnO and Zn-MHAC groups in terms of growth performance during the entire nursery period. Compared with CuSO4, Cu-MHAC tended to increase ADG (P = 0.07) and G:F (P = 0.08) during the entire nursery period. There tended to be an interaction (P = 0.09) between Cu sources and phytase on G:F during phase 2. Specifically, without phytase supplementation, there was no difference (P = 0.63) on G:F during phase 2 between Cu-MHAC and CuSO4, whereas with phytase supplementation, Cu-MHAC increased G:F during phase 2 (P = 0.05) compared with CuSO4. In conclusion, Zn-MHAC supplementation at 100 ppm could replace pharmacological level of ZnO without affecting growth performance. Cu-MHAC could improve growth performance compared with CuSO4. Cu-MHAC exerted synergistic effect with phytase on improving feed efficiency.

Abstract A total of 320 pigs (DNA 241×600; initially 10.2 kg BW) were utilized in a 21-d experiment to determine the effects of corn fractionation and pelleting technique on nursery pig growth performance. There were 5 pigs per pen, 8 pens per treatment and 8 dietary treatments in a randomized complete block design. Treatments 1–3 contained 400 µm ground corn and were fed as either mash, pelleted using a steam conditioner plus traditional vertical ring die (steam pellet) or pelleted with hot water plus a horizontal die (cold pellet). Treatments 4–6 contained corn ground to 400 µm with fines < 150 um removed and were fed as either mash, steam pellet or cold pellet. Treatments 7 and 8 contained ground corn with only fines < 150 um steam or cold pelleted prior to dietary inclusion without complete diet pelleting. Overall, pigs fed mash diets had improved (P < 0.05) ADG and d 21 BW compared to those fed steam pelleted diets with those fed cold pelleted diets being intermediate. There was no difference in G:F between pigs fed mash, steam pellet and cold pellet diets; however, pigs fed diets containing pelleted fines had decreased (P < 0.05) G:F due to an observed increased feed wastage and sorting. There was no difference in growth performance between pigs fed diets with fines removed or not. Cold pelleting was a viable option to steam pelleting in the current experiment; however, pelleting diets reduced pig performance compared to pigs fed mash diets, which was unexpected. Further research is needed to validate the response to cold pelleting when the expected response to pelleting using steam conditioning is achieved.

Abstract Benzoic acid (BA) and essential oils (EO) can minimize growth performance losses due to the removal of antibiotics and change the intestinal health of weaned piglets. The objective of this study was to evaluate the effects of BA and EO on inflammatory response, diarrhea incidence, and growth performance of the nursery phase. One hundred and twenty barrows were weaned at 23 days (6.40 ± 0.53 kg) and assigned into 3 treatments (10 replicates) in randomized block design: basal diet without additives (NC), basal diet with 200 ppm of colistin sulphate (PC), and association of 0,3% benzoic acid and essential oil (BA+EO). The feed intake and body weight were recorded at 0 and 42 days. The feces were assessed daily (per animal) and graded as normal feces (no diarrhea) or liquid or pasty stools (presence of diarrhea). On days 1, 3, and 9, blood samples were collected (5 replicates) for white blood cells (WBC) counts. Growth performance was analyzed by MIXED procedure (SAS, 2009) and the Tukey test was used to compare the means (P < 0.050). The WBC counts were analyzed by repeated-measures analysis of variance, by MIXED procedure. Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The BA+EO treatment showed a similar body weight (P = 0.014) and average daily gain (P = 0.012) than the PC group and lower feed conversion ratio (P = 0.037) compared to the NC group. The pigs of the BA+EO treatment had the lowest diarrhea incidence during the total period (P < 0.001). The supplementation with BA+EO or antibiotics reduced the counts of total WBC (P = 0.008) and neutrophils (P = 0.003). In conclusion, supplementation with BA+EO reduces the inflammatory response and the incidence of diarrhea in the nursery phase, that may be related to the improvement in the FCR.

Abstract Antibiotics growth promoting (AGP) in animal feed has been restricted. With this, several additives have been tested in order to replace AGP and ensure intestinal health. The objective of this study was to evaluate the effects of a blend of additives on growth performance, diarrhea incidence and cecal content microbiota of nursery pigs. A total of 576 weaned pigs (6.21 ± 1.16 kg) were assigned into 4 treatments (12 replicates) in randomized block design: basal diet without additives (NC); basal diet with 120 ppm of halquinol (PC); NC + 0,05% blend of lactic acid (3,5%), benzoic acid (2,5%), flavonoids (3,5%) (B5); NC+ 0,1% of same blend (B10). The pigs were weighed 0 and 42 days into the experiment. On day 10, one animal per pen (10 replicates) was euthanized for microbiota analyses. The diarrhea incidence was calculated by the percentage of visual pens with diarrhea, by day, in the period. The growth performance was analyzed by GLIMMIX procedure and the means were compared with Tukey test (P < 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P < 0.050) by statistical program STAMP. The final weight (P = 0.010) and average daily gain (P = 0.001) of B10 and PC were higher than NC. Regarding diarrhea, it was observed that the B5 and B10 had lower incidence when compared to other groups in the total period. In the microbiome analyses, it was observed that the B5, B10, and PC groups had lower (P = 0.021) biodiversity when compared to the NC piglets. However, the B5 and B10 group had higher biodiversity when compared to the PC group. In conclusion, the supplementation with 0,1% blend of additives can be a substitute for AGP.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.

The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

Abstract The objectives were to determine the digestible energy, standardized ileal digestibility of AA, and growth performance 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, 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 &lt; 0.05), but less (P &lt; 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 &lt; 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.
