Abstract This study investigated the effects of road transportation with or without homeopathic remedy (Convermax) supplementation on growth performance, nutrient digestibility, fecal microbiota, and serum cortisol and superoxide dismutase (SOD) concentrations in growing pigs. A total of 180 49-day old growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 13.17 ± 0.02 kg were randomly allotted to 2 groups based on the initial body weight, containing 18 replicates with 5 pigs (mixed sex) in each. The pigs were fed dietary supplementation of a homeopathic remedy (Convermax) (0 or 200 mg/kg of feed, as-fed) for 35 days. On day 21, forty-five pigs (70-day old; 25.25 ± 0.37 kg) were randomly selected from each group and assigned to either 2 h of road transportation or no road transportation, resulting in a 2×2 factorial design. Results showed that road transportation led to an increase in the fecal coliform bacteria counts (P = 0.023) and serum cortisol concentration (P = 0.039) and a decrease in the serum superoxide dismutase (SOD) concentration (P < 0.001). However, supplementing homeopathic remedy (Convermax) to the diet of growing pigs increased gain to feed ratio (P = 0.042), apparent nitrogen digestibility (P = 0.019), and serum SOD concentration (P = 0.007), whereas decreased serum cortisol concentration (P = 0.022). In brief, road transportation induced stress response for growing pigs and increased harmful bacteria counts in their intestines. Dietary supplementation of homeopathic remedy (Convermax) alleviated stress response, improved apparent nitrogen digestibility, and increased gain to feed ratio. However, no significant interactive effects between road transportation with or without dietary homeopathic remedy (Convermax) levels were observed on the detected parameters in growing pigs.

Homeopathic Remedy

Abstract The specialization of swine production and the market demand for pigs at different growth stages makes road transportation inevitable. However, road transportation usually causes a stress response in pigs. It is reported that homeopathic remedies supplementation could alleviate the stress response in pigs. This study investigated the effects of road transportation with or without homeopathic remedy (Convermax) supplementation on growth performance, nutrient digestibility, fecal microbiota, and serum cortisol and superoxide dismutase (SOD) concentrations in growing pigs. A total of 180 crossbred 49-d-old growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 13.17 ± 0.02 kg were randomly allotted to 2 groups based on the initial body weight, containing 18 replicates with 5 pigs (mixed sex) in each. The pigs were fed dietary supplementation of a homeopathic remedy (Convermax) (0 or 200 mg/kg of feed, as-fed) for 35 d. On day 21, 45 pigs (70-d old; 25.25 ± 0.37 kg) were randomly selected from each group and assigned to either 2 hr of road transportation or no road transportation, resulting in a 2 × 2 factorial design. We found that road transportation led to an increase in the fecal coliform bacteria counts (P = 0.023) and serum cortisol concentration (P = 0.039) and a decrease in the serum SOD concentration (P < 0.001). However, supplementing homeopathic remedy (Convermax) to the diet of growing pigs increased gain to feed ratio (P = 0.042), apparent nitrogen digestibility (P = 0.019), and serum SOD concentration (P = 0.007), whereas decreased serum cortisol concentration (P = 0.022). In brief, road transportation induced stress response for growing pigs and increased harmful bacteria counts in their intestines. Dietary supplementation of homeopathic remedy (Convermax) alleviated stress response, improved apparent nitrogen digestibility, and increased gain to feed ratio. However, no significant interactive effects between road transportation with or without dietary homeopathic remedy (Convermax) levels were observed on the detected parameters in growing pigs.

Abstract This study was carried out to assess the effects of dietary supplementation of enzymatic bio-conversion of Scuterallia baicalensis (SB) extract on the growth performance, nutrient digestibility, fecal microbiota, fecal gas emission, blood hematology, and antioxidative indicators in growing pigs. A total of 200 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight of 24.52 ± 1.99 kg were used in a 42-day experiment with a completely randomized block design. Pigs were randomly divided into 4 treatment groups with 10 replicate pens per treatment and 5 animals per pen (2 barrows and 3 gilts). There were four diet conditions: 1) CON, basal diet; 2) TRT1, basal diet + 0.1% apramycin; 3) TRT2, basal diet + 0.1% SB extract; 4) TRT3, basal diet + 0.1% enzymatic bio-conversion of SB extract. The pen was taken as the experimental unit. Tukey’s multiple range test was used for evaluation of differences among the treatments. Compared with the CON group, TRT1 or TRT3 groups had higher final body weight (BW) (P = 0.074) and average daily gain (ADG) (P = 0.075), and lower feed conversion ratio (FCR) (P = 0.054). The apparent total tract digestibility (ATTD) of dry matter (DM) (P = 0.095) in TRT1 group was higher than that in CON group. Serum glutathione peroxidase (GPX) (P = 0.047) and glutathione (GSH) (P = 0.074) concentrations in TRT3 group were higher than those in CON or TRT1 groups. However, there were no significant differences in fecal microbiota, fecal gas emission, and blood hematology among all dietary groups. A positive correlation between apramycin supplementation in the diet and ADG and the ATTD of DM were observed. A positive correlation between enzymatic bio-conversion of SB extract supplementation in the diet and ADG and the concentration of GPX and GSH in serum were also observed.

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

The Impact

Abstract The objective of this project was to determine the impact of feeding growing pigs with high wheat millrun diets supplemented with a multi-carbohydrase enzyme (amylase, cellulase, glucanase, xylanase, and invertase activities) on nutrient digestibility, growth performance, and greenhouse gas (GHG) output (carbon dioxide, CO2; nitrous oxide, N2O; methane, CH4). Three experiments were conducted utilizing six treatments arranged as a 3 × 2 factorial (0%, 15%, or 30% wheat millrun; with or without enzyme) for the digestibility experiment or as a 2 × 2 factorial (0% or 30% wheat millrun; with or without enzyme) for the performance and GHG experiments. The digestibility, performance, and GHG experiments utilized 48 individually housed pigs, 180 pigs housed 5 per pen, or 96 pigs housed 6 per chamber, respectively. Increasing wheat millrun up to 30% in the diet of growing pigs resulted in decreased energy, nitrogen (N) and phosphorus (P) apparent total tract digestibility and net energy content (P < 0.01). Overall, average daily gain (ADG) and gain to feed ratio were reduced in pigs fed wheat millrun (P < 0.05). Enzyme supplementation had minimal effects on the digestibility or performance parameters measured. Feeding diets with 30% millrun did not affect GHG output (CH4: 4.7 and 4.9; N2O: 0.45 and 0.42; CO2: 1,610 and 1,711 mg/s without or with millrun inclusion, respectively; P > 0.78). Enzyme supplementation had no effect on GHG emissions (CH4: 4.5 and 5.1; N2O: 0.46 and 0.42; CO2: 1,808 and 1,513 mg/s without or with enzymes, respectively; P > 0.51). Overall, the carbohydrase enzyme had minimal effects on parameters measured, regardless of wheat millrun inclusion (P > 0.10). Although energy, N and P digestibility, and ADG were reduced, the inclusion of up to 30% wheat millrun in the diet has no effect on GHG emissions from growing pigs (P > 0.10).

A total of 160 growing pigs (24.69 ±1.89 kg) were randomly assigned to 1 of 4 treatments in a 2 x 2 factorial design with two different levels of nutrient density diet with or without 0.3 % probiotic (Lactobacillus plantarum). Each treatment has 8 replicates with 5 pigs (3 gilts and 2 barrows) per pen. At the end of the trial, pigs fed 0.3% probiotic supplement has significantly increased the body weight, while average daily gain and gain to feed ratio was significantly increased in both probiotic and high nutrient density (HD) diet. The nutrient digestibility of dry matter was significantly increased in pigs fed HD diet whereas, nitrogen and energy digestibility and blood characters immunoglobulin and lymphocyte counts were significantly increased in both HD and probiotic groups. Inclusion of HD diet with 0.3% probiotic had significantly decreased NH3 and H2S gas emission. Moreover, nitrogen and energy showed a significant interaction between probiotic and density diet. In summary, dietary probiotics with HD diet had positively enhanced the growth performance, nutrient digestibility, blood profile and reduced gas emission. We suggest that 0.3% probiotic with HD diet could serve as an alternative feed additive to enhance the growth performance of growing pigs.

Woyengo, T. A., Akinremi, O. O., Rossnagel, B. G. and Nyachoti, C. M. 2012. Performance and total tract nutrient digestibility of growing pigs fed hulless low phytate barley. Can. J. Anim. Sci. 92: 505–511. An experiment was conducted to determine the performance and nutrient digestibility of growing pigs fed hulless low phytate (HLP) barley without or with phytase for 28 d. Twenty-four growing pigs (average initial body weight=25.3 kg) were fed three diets in a completely randomised design. The diets included a regular-hulled barley-based diet, and a HLP barley-based diet without or with phytase at 500 phytase units kg−1. Pigs fed the HLP barley-based diet without phytase had greater (P<0.05) average daily gain (0.911 vs. 0.717 kg), and apparent total tract digestibility of dry matter, energy, P, Mg, and Na were higher (P<0.05) than the regular barley-based diet. Supplementation of phytase to the HLP barley-based diet resulted in improved (P<0.05) feed conversion efficiency (0.506 vs. 0.547 kg kg−1), and apparent total tract digestibility of N, P and K. In conclusion, pigs fed the HLP barley-based diet had higher growth performance and nutrient digestibility than those fed the regular-hulled barley-based diet, indicating that the HLP barley is a better source of nutrients for pigs than regular barley. Phytase supplementation to the HLP barley-based diet can result in a further increase in nutrient utilisation by pigs.

Abstract Two experiments were conducted to determine effects of extrusion on energy and nutrient digestibility in soybean hulls. One source of soybean hulls was ground and divided into two batches. One batch was used without further processing, whereas the other batch was extruded. In Exp. 1, four diets were formulated to determine crude protein (CP) and amino acid (AA) digestibility in soybean hulls. A soybean meal-based diet in which soybean meal provided all the CP and AA was formulated. Two diets were formulated to contain 30% nonextruded or extruded soybean hulls and 18% soybean meal. An N-free diet that was used to determine the endogenous losses of CP and AA was also used. Eight growing barrows (initial body weight = 37.0 ± 3.9 kg) had a T-cannula installed in the distal ileum and were allotted to a replicated 4 × 4 Latin square design. Each experimental period lasted 7 d with the initial 5 d being the adaptation period and ileal digesta were collected for 8 h on day 6 and 7. Results indicated that extrusion of soybean hulls did not change the standardized ileal digestibility (SID) of CP and most AA with the exception that the SID of Ile and Leu tended (P &lt; 0.10) to be greater in extruded than nonextruded soybean hulls. In Exp. 2, three diets were formulated to determine energy digestibility in soybean hulls. One corn-soybean meal based basal diet, and two diets that contained corn, soybean meal, and 32% extruded or nonextruded soybean hulls were formulated. Twenty-four growing barrows (initial body weight = 59.9 ± 3.4 kg) were allotted to a randomized complete block design. Pigs were housed individually in metabolism crates and feces and urine were collected separately for 4 d after 5 d of adaptation. The apparent total tract digestibility (ATTD) of gross energy (GE) and the digestible energy (DE) and metabolizable energy (ME) were reduced (P &lt; 0.05) in diets containing nonextruded or extruded soybean hulls compared with the basal diet. However, the ATTD of GE and values for DE and ME in soybean hulls were not improved by extrusion. Likewise, extrusion did not change the concentration of total dietary fiber in soybean hulls. In conclusion, there were no effects of extrusion of soybean hulls on SID of AA, energy digestibility, or ME concentration in soybean hulls.

Fermented bamboo vinegar liquid (FBVL) was prepared through liquid fermentation of bamboo vinegar with multispecies probiotics, and its effect on growing pigs was investigated. A 42-day feeding trial with 84 growing pigs (28.0 ± 0.08 kg) was conducted to evaluate the effects of FBVL on growth performance, nutrient digestibility, faecal Escherichia coli concentration and faecal ammonia emissions. Pigs were randomly distributed to one of four dietary treatments, namely control, CTC (0.003% chlortetracycline), FBVL 0.2%, and FBVL 0.4%. Overall, the final weight and daily weight gain of the pigs in the CTC group were higher than that of pigs in the control group. Dietary supplementation with 0.4% FBVL reduced the feed intake of growing pigs, whereas the feed conversion ratio (FCR) was lower in the CTC supplemented group. The dry matter digestibility was higher in pigs fed CTC and 0.2% FBVL diets, and crude protein digestibility was improved in all treatment groups compared with control. The faecal E. coli numbers were reduced in response to CTC and 0.4% FBVL supplementation. Faecal ammonia emissions were reduced by dietary supplementation with CTC and FBVL at weeks 1, 2 and 3. In conclusion, dietary FBVL supplementation increased nutrient digestibility and reduced faecal E. coli population and ammonia emissions without negative effects on growth performance.Keywords: Chlortetracycline, digestibility, fermentation, probiotics, swine

The present experiment was to evaluate the effects of dietary Spirulina (SP) supplementation in growing pigs. A total of 140 pigs [(Landrace × Yorkshire) × Duroc, 25.32 ± 1.36 kg] were randomly distributed to one of four treatments: control, basal diet; treatment 1, basal diet + 0.025% SP; treatment 2, basal diet + 0.050% SP; and treatment 3, basal diet + 0.100% SP. Growing pigs fed 0.050% SP diet had greater (P < 0.05) body weight and fecal Lactobacillus counts compared with pigs fed basal diet. Average daily gain and gain to feed ratio were greater (P < 0.05) in pigs fed 0.050% and 0.100% SP diets as compared with pigs fed basal diet. The apparent total tract digestibility (ATTD) of dry matter (DM) and superoxide dismutase (SOD) activity for pigs fed 0.050% SP diet tended to increase compared with pigs fed basal diet (P < 0.10). Pigs fed 0.025%, 0.050%, and 0.100% SP had a higher (P < 0.05) glutathione peroxidase (GPx) activity than pigs fed basal diet. In conclusion, SP supplementation improved growth performance and ATTD of DM, increased the SOD and GPx activity, and enhanced the fecal Lactobacillus counts in growing pigs.
