AbstractTwo experiments were conducted to investigate the use of dietary manipulation as a means of improving piglet post-weaning performance and gastro-intestinal health. In experiment 1, 144 piglets (24 days old) in a 3 × 2 factorial arrangement were offered diets containing 65, 170 and 280 g lactose per kg with or without lactic acid (16 g/kg) for 28 days. In experiment 2, 20 piglets (24 days old) (in a 2 × 2 factorial arrangement were offered the following diets for 7 days and then sacrificed: T1) basal diet; T2) basal diet + 15 g inulin per kg; T3) basal diet + 16 g lactic acid per kg and T4) basal diet + 15 g inulin per kg + 16 g lactic acid per kg. After slaughtering, tissue samples were taken from the duodenum, jejunum and ileum for morphological measurements. Digesta samples were taken from the ileum, caecum and colon for microbiology and volatile fatty acid analysis. In experiment 1, pigs offered diets containing lactic acid had improved daily gain (P< 0·01) and food efficiency (P< 0·05) from days 0 to 7 compared with pigs offered diets containing no lactic acid. There was a linear increase (P< 0·05) in average daily gain (ADG) from days 0 to 28 and a linear decrease in faecal pH (P< 0·01) with increasing lactose levels. There was a quadratic effect of lactose on food conversion ratio from days 0 to 28 (P< 0·05). In experiment 2, there was a significant interaction between inulin and lactic acid in villous height in the jejunum (P< 0·001) and the concentrations of lactobacilli (P< 0·1) andE. coli(P< 0·05) in the colon. The inclusion of inulin and lactic acid resulted in a significant increase in villous height compared with the inulin only diet (P< 0·001). However, lactic acid had no effect on villous height in pigs offered diets without inulin supplementation. The inclusion of lactic acid and inulin caused a significant increase in both lactobacilli andE. coliconcentrations compared with the inulin only diets (P< 0·05). However, neither inulin nor lactic acid had an effect on lactobacilli andE. colinumbers in isolation of the other. In conclusion, in experiment 1, lactic acid improved performance in the 1st week post weaning. There was a linear increase in ADG with increasing lactose levels. In experiment 2, the combination of lactic acid and inulin increased villous height in the jejunum and concentrations of lactobacilli andE. coliin the colon.

Diarrhea Incidence

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 &lt; 0.050) (SAS, 2009). Diarrhea incidence was analyzed by GENMOD procedure (SAS, 2009). The Kruskal Wallis test was used to compare microbial biodiversity (P &lt; 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.

This study aimed to investigate the effects of dietary LY or LY combined with ZnO supplementation on performance and gut health in nursery pigs. 192 Duroc × Landrace × Yorkshire piglets (weaned on d 32 of the age with 9.2 ± 1.7 kg BW) were allocated into four treatments with eight replicate pens, six piglets per pen. The treatments included a basal diet as control (CTR), an antibiotic plus ZnO diet (CTC-ZnO, basal diet + 75 mg/kg of chlortetracycline + ZnO (2000 mg/kg from d 1 to 14, 160 mg/kg from d 15 to 28)), a LY diet (LY, basal diet + 2 g/kg LY), and a LY plus ZnO diet (LY-ZnO, basal diet + 1 g/kg LY + ZnO). The results showed that pigs fed LY or LY-ZnO had increased (p < 0.05) average daily gain, serum IgA, IgG, superoxide dismutase, fecal butyric acid, and total volatile fatty acid concentrations, as well as decreased (p < 0.05) feed conversion ratio and diarrhea rate compared with CTR. In conclusion, pigs fed diets with LY or LY combined with ZnO had similar improvement to the use of antibiotics and ZnO in performance, antioxidant status, immunoglobulins, and gut health in nursery pigs.

AbstractA total of 384 piglets from a three-way cross Yorkshire ♂ × (Finnish Landrace ♂ × Dutch Landrace♀) ♀ in the live-weight range of 11 to 25 kg were used in a feeding trial. The effect of supplementary microbial phytase from Aspergillus niger var. Van Tieghem on performance (average daily gain (ADG), average daily food intake (ADFI) and food conversion ratio (FCR)) and apparent digestibility of total phosphorus (P), in comparison with a non-supplemented basal diet or a diet supplemented with one or two levels of monocalcium phosphate (MCP), were studied.The piglets were allotted to 12 blocks. Within each block, four experimental diets were offered ad libitum for a period of 4 weeks i.e. (1) basal diet; (2) basal diet + 1·0 g P, from MCP per kg diet; (3) basal diet + 1·9 g P, from MCP per kg diet; and (4) basal diet + 1450 phytase units (PTU) per kg diet. The diets, with added chromium III oxide as a marker, were cold pelleted without steam at a temperature not above 60°C to avoid a possible inactivation of the phytase. In all diets the ratio calcium: digestible P was intended to be constant.Adding 1450 PTU of Aspergillus niger phytase enhanced the apparent digestibility of P by proportionately 0·216 when compared with diet 1 and by proportionately 0·100 compared with diet 3. In addition, significantly higher ADG and ADFI and better FCR were noted in pigs receiving supplementary microbial phytase than in pigs on any other treatment. The content of digestible P of the diet with added phytase, however, zvas between the two levels of the diets with added MCP.

Abstract Object: The aim of this experiment was to study the effects of different levels of glutathione (GSH) on growth performance and intestinal health of piglets. Methods: A total of 180 piglets of 21-day-old (Duroc × Landrace × Large White) were randomly divided into 5 groups. The control group was fed a standard diet based on NRC 2012. The treatment group 1 - 4 was supplemented with 50, 100, 200 and 400mg/kg GSH. The experiment lasted 28 days. Results: Compared with the control group, 50mg/kg GSH significantly increased the piglet’s skin and gross color, average daily gain (ADG) and decreased feed gain ratio (F/G) (P &lt; 0.05), while the effect of 100, 200, 400 mg/kg GSH was contrary. The supplementation of 50mg/kg GSH significantly increased the mucosal villi height, the ratio of villous height to crypt depth (VH/CD) and decreased the crypt depth (P &lt; 0.05) in duodenum, jejunum and ileum (P &lt; 0.05), while the effect of 100, 200, 400 mg/kg GSH was contrary; The supplementation of 50mg/kg GSH decreased the concentration of triglyceride in plasma (P &lt; 0.05); The supplementation of 50, 100, 200, 400mg/kg GSH had no effect on the antioxidative indexes of blood, but 400mg/kg GSH increased the activities of T-AOC, GSH, SOD and decreased MDA content in jejunum and ileum; 400mg/kg GSH increased the content of T-SOD in liver (P &lt; 0.05), while 50mg/kg GSH had no effect on SOD, GSH-PX, GSH-SOD in intestine and liver (P &gt; 0.05). 50mg/kg GSH significantly increased T-AOC activity and decreased MDA content in muscle (P &lt; 0.05). Conclusion: Supplementation of 50mg/kg GSH in piglets` diet was the most appropriate and it could significantly improve skin and gross color, growth performance and intestinal mucosal morphology, it also increased the antioxidation ability in muscle of piglets.

A total of 45 sows (Landrace × Yorkshire) and their litters were used in this study to evaluate the efficacy of nucleotide supplementation on reproductive performance, growth performance, fecal microflora, and blood profiles in sows and piglets. Sows were allocated to one of three treatments (15 pigs per treatment and the average parity was 4.13). Dietary treatments consisted of (1) CON: basal diet, (2) T1: CON + 0.5% nucleotides, and (3) T2: CON + 1.0% nucleotides. In this study, the average daily feed intake during lactation and back fat at weaning day was increased linearly (P < 0.05) in sows with the increase in nucleotide supplementation levels. Sows receiving increasing levels of nucleotides had linearly increased fecal Lactobacillus counts and decreased Escherichia coli counts at weaning day (P < 0.05). Linear reduction of the epinephrine, norepinephrine, and cortisol in sows was observed at weaning day, whereas superoxide dismutase was increased linearly (P < 0.05). Body weight and average daily gain in piglets were linearly (P < 0.05) increased with the increasing levels of nucleotides. Linear increase (P < 0.05) was also observed on total piglets born, live piglets, and piglet survival. The current study demonstrated the importance of nucleotides in the diets of sows to improve sow and piglet performance.

This study investigated the effects of xylo-oligosaccharide (XOS) and flavomycin (FLA) on the performance and immune function of broiler chickens. A total of 150 ArborAcres broilers were randomly divided into three groups and fed for six weeks from one day of age in cascade cages. The diets of each test group were (1) a basal diet, (2) the basal diet supplemented with 2 mg/kg FLA, and (3) the basal diet supplemented with 2 mg/kg XOS. At 21 and 42 days, the growth performance index values and short-chain fatty acid (SCFA) concentrations in the cecum were quantified. Furthermore, immunoglobulin G (IgG) and plasma interleukin 2 (IL-2) as well as mRNA expression of LPS-Induced TNF-alpha Factor (LITAF), Toll-like receptor-5 (TLR5) and interferon gamma (IFNγ) in the jejunum were quantified. The results showed that administration of XOS or FLA to chickens significantly improved the average daily gain. Supplementation with XOS increased acetate and butyrate in the cecum, while FLA supplementation increased propionate in the cecum. An increase in plasma IgG was observed in XOS-fed 21-day-old broilers, but FLA supplementation decreased IgG in the plasma of 42-day-old broilers and increased plasma IL-2. Furthermore, FLA or XOS supplementation downregulated mRNA expression of IFNγ, LITAF and TLR5. The above data suggest that addition of XOS and FLA to the diet could improve the growth performance of broilers and reduce the expression of cytokine genes by stimulating SCFA.

Abstract It was aimed to simultaneously study standardized ileal digestible (SID) tryptophan (Trp) and lysine (Lys) for gilts. A digestibility assay was previously conducted to determine the SID amino acid in the basal diet (low levels of SID Trp and Lys). Sixty-four gilts (15.04 ± 1.44 kg) were allotted to 16 diets in a 4 × 4 factorial arrangement (1.55, 1.85, 2.15 and 2.45 g/kg SID Trp and 9.72, 11.12, 12.52 and 13.92 g/kg SID Lys) with four replicates per treatment. Performance, longissimus muscle (LM), backfat thickness (BF) and blood variables were evaluated. An interaction was observed for G:F, and by response surface model, the optimum Trp level was achieved at 2.15 g/kg (0.159 g/MJ of ME). A quadratic effect of Trp was observed on body weight (BW) and average daily gain (ADG); the daily feed intake increased linearly as Trp increased. The optimum Trp levels of 2.25 and 2.24 g/kg were estimated for BW and ADG, respectively. The BF increased with increasing levels of Trp. There was a quadratic and linear effect of Trp and Lys, respectively, on the LM, in which the optimum Trp level was determined as 2.05 g/kg in the diet. Plasma urea nitrogen decreased as Trp and Lys levels increased. Using estimates provided by response surface, maximized G:F ratio was obtained at 2.15 g SID Trp/kg of diet and at least 13.92 g SID Lys/kg of diet is necessary to optimize the G:F for 15–30 kg gilts, providing a Trp:Lys ratio of 15.4:100.

This experiment was conducted to determine the effect of dietary inclusion of phytogenic blends on the performance of sows during the gestating and lactating periods and suckling piglets. Fifty-one multiparous sows (Landrace × Yorkshire) were randomly distributed into three treatments (17 sows per treatment): T1 (basal diet); T2 (T1 + 0.05% AC blend (Astragalus membranaceus and Chinese Liquorice); T3 (T1 + 0.05% SL blend (Scutellaria baicalensis and Lonicera japonica). Feeding the sows with diets supplemented with AC and SL blends decreased (P < 0.05) bodyweight loss after farrowing to weanling. The number of piglets, average daily feed intake, backfat thickness, and oestrus interval was not influenced (P > 0.05) by diets. Suckling piglets of sows fed with AC and SL blends showed higher (P < 0.05) weanling bodyweight and average daily gain weight. Piglet survival rate and birthweight were not affected by treatments. Feeding sows with AC and/or SL blends did not significantly influence the composition of colostrum or milk. There was not any significant impact on faecal score of suckling piglets. These results indicated that supplementation of phytogenic blends to the diet of sows during gestating and lactating period led to a decline in bodyweight loss after farrowing and could improve litter performance.

Abstract An experiment was conducted to test the hypothesis that Val from a Val-containing fermentation biomass product (Val-FB; 64.4% L-Val) has a bioavailability of 100% relative to L-Val (98% Val) when fed to weanling pigs. A Val-deficient basal diet containing 0.63% standardized ileal digestible (SID) Val was formulated. Six additional diets were prepared by supplementing the basal diet with 0.08, 0.16, or 0.24% L-Val or 0.12, 0.25, or 0.37% Val-FB to create experimental diets containing 0.71, 0.79, or 0.87% SID Val. A total of 224 weanling pigs (6.87 ± 0.64 kg) were allotted to a randomized complete block design with 7 diets and 8 replicate pens per diet. Diets were fed for 21 d and growth performance was measured on a pen basis. Orthogonal-polynomial contrasts were used to determine linear and quadratic effects of L-Val and Val-FB levels on performance and the effect of Val sources. A linear regression model based on performance was used to estimate the relative bioavailability (RBV) of Val in Val-FB relative to L-Val. The final body-weight (BW) and average-daily-gain (ADG) were greater (P < 0.01) for pigs fed diets supplemented with Val-FB than pigs fed diets supplemented with L-Val (Table 1). The average-daily-feed-intake (ADFI) decreased linearly (P < 0.01), whereas gain-to-feed ratio (G:F) increased (P < 0.01) by supplementing graded levels of both Val sources to the diets. The RBV of Val in Val-FB as determined by ADG, G:F, and final BW was 146, 135, and 143%, respectively, with 95% confidence intervals of 99 to 191%, 83 to 187%, and 70 to 217%, respectively. In conclusion, the linear regression estimated a RBV of at least 100% for Val-FB relative to L-Val, and pigs fed diets supplemented with Val-FB had greater ADG and final BW than pigs fed diets supplemented with the same amount of L-Val.

AbstractFour litters produced by father-daughter matings (back crosses) resulting in 35 animals with a theoretical inbreeding coefficient of 25% were typed with 21 independent informative markers. The differences between the two founder animals were estimated, based on the marker information, and it was found that the founder boar had higher genetic potential for proportion of lean meat and lower genetic potential for groivth than the founder sow. The proportion of the genome of each offspring which was identical by descent was investigated. On the basis of these markers the realized inbreeding was found to vary between 7 and 47%. The linear decrease in weight at days 1, 26 and 136, average daily gain and proportion of lean meat regressed on the realized inbreeding were estimated to 0·6 kg, 2·4 kg, 18 kg, 95 g/day and 15 g/kg, respectively. For weight at day 88 a corresponding linear increase of 11 kg was observed. The joint effect of founder differences and realized inbreeding were as expected negative and statistically significant for all growth traits.
