Context Dietary supplementation of essential oils or in combination with a Bacillus probiotic was investigated as an antibiotic growth promoter for weaned pigs. Aims To evaluate the effect of essential oils (i.e. thymol and carvacrol mixture) or in combination with a probiotic strain (i.e. Bacillus subtilis PB6) on the growth performance, diarrhoea incidence, ammonia emission and serological profiles of weaned pigs. Methods A total of 96 crossbred ([Yorkshire × Landrace] × Duroc) weaned pigs were randomly allotted to one of six treatments based on sex and initial bodyweight. Each group was distributed into four replicates with four pigs each according to a randomised complete block design. The treatments were: (i) positive control, basal diet supplemented with colistin 150 g/tonne and amoxicillin 200 g/tonne; (ii) negative control, basal diet without supplementation; (iii) T3, basal diet supplemented with essential oils 300 g/tonne; (iv) T4, basal diet supplemented with essential oils 600 g/tonne; (v) T5, basal diet supplemented with essential oils 1000 g/tonne; and (vi) T6, basal diet supplemented with essential oils 300 g/tonne diet and Bacillus probiotics 1000 g/tonne. Key results The piglets fed with supplements had a significantly higher average daily gain and lower incidence of diarrhoea than the piglets in the negative control (P = 0.001). Feeding the essential oils alone or in combination with probiotics significantly reduced faecal ammonia emission (P = 0.027) and blood urea nitrogen (P = 0.039), while markedly increasing the serum immunoglobulin G concentration of weaned pigs compared with the negative control treatment (P = 0.014). The difference in time of blood collection had significant effects on blood urea nitrogen and immunoglobulins (P = 0.001). However, no significant differences emerged in average daily feed intake, gain: feed ratio, feed efficiency and antibody against swine fever among the treatments. Conclusions Diet supplementation with essential oils or in combination with probiotics improved growth performance and immunity, and lowered ammonia emissions and diarrhoea incidence of weaned pigs. Implications These findings provide a basis for the application of phytogenic compounds and probiotics as antibiotic growth promoter alternatives in post-weaning diets for pigs.

Abstract This study was conducted to investigate the effects of a direct-fed microbial (DFM) product (Bacillus subtilis strain DSM 32540) in weaned pigs challenged with K88 strain of Escherichia coli on growth performance and indicators of gut health. A total of 21 weaned pigs [initial body weight (BW) = 8.19 kg] were housed individually in pens and fed three diets (seven replicates per diet) for 21 d in a completely randomized design. The three diets were a corn-soybean meal-based basal diet without feed additives, a basal diet with 0.25% antibiotics (neo-Oxy 10-10; neomycin + oxytetracycline), or a basal diet with 0.05% DFM. All pigs were orally challenged with a subclinical dose (6.7 × 108 CFU/mL) of K88 strain of E. coli on day 3 of the study (3 d after weaning). Feed intake and BW data were collected on days 0, 3, 7, 14, and 21. Fecal scores were recorded daily. On day 21, pigs were sacrificed to determine various indicators of gut health. Supplementation of the basal diet with antibiotics or DFM did not affect the overall (days 0–21) growth performance of pigs. However, antibiotics or DFM supplementation increased (P = 0.010) gain:feed (G:F) of pigs during the post-E. coli challenge period (days 3–21) by 23% and 24%, respectively. The G:F for the DFM-supplemented diet did not differ from that for the antibiotics-supplemented diet. The frequency of diarrhea for pigs fed a diet with antibiotics or DFM tended to be lower (P = 0.071) than that of pigs fed the basal diet. The jejunal villous height (VH) and the VH to crypt depth ratio (VH:CD) were increased (P < 0.001) by 33% and 35%, respectively, due to the inclusion of antibiotics in the basal diet and by 43% and 41%, respectively due to the inclusion of DFM in the basal diet. The VH and VH:CD for the DFM-supplemented diet were greater (P < 0.05) than those for the antibiotics-supplemented diet. Ileal VH was increased (P < 0.05) by 46% due to the inclusion of DFM in the basal diet. The empty weight of small intestine, cecum, or colon relative to live BW was unaffected by dietary antibiotics or DFM supplementation. In conclusion, the addition of DFM to the basal diet improved the feed efficiency of E. coli-challenged weaned pigs to a value similar to that of the antibiotics-supplemented diet and increased jejunal VH and VH:CD ratio to values greater than those for the antibiotics-supplemented diet. Thus, under E. coli challenge, the test DFM product may replace the use of antibiotics as a growth promoter in diets for weaned pigs to improve feed efficiency and gut integrity.

Abstract This study was performed to investigate the effects of dietary supplementation with garlic and turmeric powder as growth promoter agents on performance, carcass traits, serum biochemistry, and antioxidant enzyme activities of growing rabbits. A total of 112 New Zealand White rabbits (NZW) at 5 weeks of age were randomly assigned to seven treatments with four replicates. The dietary treatments consisted of 7 groups as follows; the basal diet as control, phytogenic additives groups were supplemented with 2, 4, and 6 g/kg garlic or turmeric powder added to the basal diet. There were no linear and quadratic differences (P<0.05) in growth performance after garlic or turmeric supplementation at all studied ages. Compared with the control group, supplementation of diets with garlic or turmeric linearly and quadratically elevated immunity biomarkers such as total protein (TP), albumin (AL) and immunoglobulin (IgG) levels and decreased (linearly and quadratically, P<0.05) aspartate aminotransferase (AST), alanine aminotransferase (ALT ), triglyceride (TG) and total cholesterol (TC) levels in rabbit serum. However, TP, AL, globulin (GL), IgG and IgM levels were linearly and quadratically enhanced with increasing turmeric levels versus the control diet. Hepatic superoxide dismutase (SOD), catalase (CAT ) and glutathione peroxidase GSH-Px activities as well as reduced glutathione (GSH) concentrations were linearly and quadratically (P<0.05) improved in garlic or turmeric additives fed groups. While MDA concentration was statistically (linearly, P= 0.022) reduced in comparison with the control group. It could be concluded that garlic or turmeric supplementation (2, 4 and 6 g/kg) did not linearly and quadratically affect growth performance but improved the immunity responses and lowered the lipid profile in blood and lipid peroxidation in liver and increased hepatic antioxidant activity in treated rabbits.

The efficacy of yeast-based mycotoxin detoxifiers on health and growth performance of newly-weaned pigs (27-d-old) fed diets naturally contaminated with deoxynivalenol was investigated. Sixty pigs were individually assigned to five treatments for 34 d: NC (negative control, 1.2 mg/kg of deoxynivalenol); PC (positive control, 3.2 mg/kg of deoxynivalenol); CYC (PC + clay/yeast culture-based product, 0.2%); CYE (PC + clay/yeast cell wall/plant extracts/antioxidants-based product, 0.2%); and CYB (PC + clay/inactivated yeast/botanicals/antioxidants-based product, 0.2%). Blood and jejunal mucosa were sampled, and data were analyzed using Proc Mixed of SAS with pre-planned contrasts. Deoxynivalenol reduced the average daily gain (ADG) in phase 3. Pigs fed CYC had greater overall ADG, average daily feed intake during phase 3, and gain to feed ratio during phase 2 than PC. At d 14, deoxynivalenol reduced blood urea nitrogen/creatinine and tended to reduce blood urea nitrogen. Pigs fed CYB tended to have greater aspartate aminotransferase than PC. At d 34, pigs fed CYC and CYB tended to have lower serum creatine phosphokinase than PC. Pigs fed CYE had lower blood urea nitrogen/creatinine than PC. In jejunal mucosa, deoxynivalenol tended to increase malondialdehydes and decrease glutathione. Pigs fed CYE and CYB had lower malondialdehydes, pigs fed CYB had greater glutathione and tended to have lower immunoglobulin A than PC. Pigs fed CYC and CYE tended to have lower interleukin 8 than PC. In summary, deoxynivalenol challenge (1.2 vs. 3.2 mg/kg) mildly compromised growth performance and increased the oxidative stress of pigs. Mycotoxin detoxifiers could partially overcome deoxynivalenol toxicity enhancing liver health, whereas CYE and CYB reduced oxidative stress, and CYC and CYB reduced immune activation. In conclusion, yeast-based detoxifiers with functional components as clay/inactivated yeast/botanicals/antioxidants had increased detoxifying properties in newly-weaned pigs challenged with deoxynivalenol, potentially by enhancing adsorbability, immune function, gut health, and reducing oxidative stress.

This experiment was conducted to evaluate the effects of copra meal (CM) inclusion level on the growth performance, apparent total tract digestibility (ATTD), blood urea nitrogen (BUN) concentrations, and pork quality of growing-finishing pigs fed diets containing β-mannanase. Eighty crossbred pigs with average body weight (BW) of 27.22 ± 0.09 kg were allotted to five dietary treatments with four pigs per pen and four replicates per treatment based on sex and BW. The dietary treatments were: (1) NC: negative control, corn-soybean meal (SBM) based basal diet, (2) PC: positive control, basal diet + 0.10% β-mannanase (800 IU/ kg diet), (3) CM6: PC diet with 6% CM inclusion, (4) CM12: PC diet with 12% CM inclusion, and (5) CM18: PC diet with 18% CM inclusion in a three-phase feeding program (growing: 0–6 weeks, finishing I: 7–9 weeks, and finishing II: 10–12 weeks). The quadratic responses were observed in the BW at six weeks (p < 0.05), ADG in the growing phase (0–6 weeks; p < 0.05), and ADFI in the finishing phase with a tendency (7–12 weeks; p = 0.06) as the inclusion level of CM increased. However, the BW at 12 weeks (linear, p < 0.05 and quadratic, p = 0.06), the overall ADG (0–12 weeks; linear and quadratic, p < 0.05), and the G:F ratio in the finishing (7–12 weeks; linear, p < 0.05) and overall (0–12 weeks; linear, p < 0.05) phases decreased with increasing levels of CM in the diets. The ATTD of crude protein (linear, p < 0.05), crude fiber (linear, p < 0.05), and ash (linear, p < 0.05) decreased linearly as the inclusion level of CM increased. The BUN concentrations increased linearly with increasing levels of CM in the diets at 12 weeks of the experiment (p < 0.05). As the inclusion level of CM increased, TBARS value at d 3 post-mortem (linear, p = 0.07) tended to increase, whereas initial loin pH at 1 h post-mortem decreased (linear and quadratic, p < 0.05) with no difference in ultimate loin pH at 24 h post-mortem. These results indicated that CM inclusion up to 12% in the growing-finishing pig diets with β-mannanase did not affect growth performance, nutrient utilization, and pork quality whereas 18% CM inclusion to the diets could negatively impact nutrient digestibility, BUN concentrations, and thereby growth performance.

This study was conducted to investigate the effects of dietary supplementation with different organic acid (<b>OA</b>) mixtures on growth performance, nutrient digestibility, and gut morphology in weaned pigs. A total of 56 weaned pigs (7.93 ± 1.04 kg body weight) were assigned to four dietary treatments with seven replicates per treatment for a 35-d study conducted over two phases; phase 1 (d 1 to 14) and phase 2 (d 14 to 35). Diets consisted of 1) a corn-soybean meal-basal diet without any additive (negative control, <b>NC</b>); 2) NC + formic and propionic acids (<b>TRT1</b>); 3) NC + butyric, formic, and propionic acids (<b>TRT2</b>); and 4) NC + antibiotic (positive control, <b>PC</b>). During the overall period, the gain to feed ratio of pigs fed the PC and TRT1 diets tended to be higher (<i>P</i> = 0.059) than that of the NC diet. However, OA supplementation had no effects on nutrient digestibility. Jejunal villus height to crypt depth ratio was higher (<i>P</i> < 0.05) in pigs fed the TRT1 diet than those fed the NC diet. In conclusion, dietary OA supplementation tended to increase overall feed efficiency and improved gut morphology in weaned pigs.

A study was conducted at AFU livestock farm, Rampur, Chitwan in 2017-18 to determine the effect of dietary supplementation of garlic and ginger in different combination on feed intake, growth performance and economics by using commercial Cobb 500 broilers. A total of two hundred, 11-day-old chicks were allocated randomly to five different treatments. The experiment was designed in a Completely Randomized Design, each treatment with four replication and each replication had 10 birds. They were fed isoproteinous and isocaloric Basal diet (BD) and BD supplemented with four different levels of garlic and ginger such as T1 (BD only), T2 (BD + 1% garlic); T3 (BD + 1.0% ginger); T4 (BD + 0.5% garlic and 0.5% ginger) and T5 (BD + 1% garlic and 1% ginger). Weekly average body weight, weight gain, feed consumption, and feed efficiency were recorded up to sixth week of age. All data were statistical analyzed using Completely Randomized Design. The results showed that overall feed consumption was significantly (P≤0.05) higher for broiler fed diet supplemented with 0.5% garlic and 0.5% ginger (T4) followed by T5 (basal diet with 1% garlic and 1% ginger). On the other hand significantly higher (P≤0.01) cumulative weekly live body weight and body weight gain (g/bird) was found for the treatment with supplemented 1% garlic powder (T2), followed by broiler fed diet supplemented with 0.5% garlic and 0.5% ginger powder (T4). Similarly, feed conversion ratio was significantly (P≤0.01) better in broiler fed basal diet with supplementation of 1% garlic (T2) followed by basal diet with supplementation of 0.5% garlic and 0.5% ginger (T4). The maximum benefit was obtained from the broiler fed basal diet with supplementation of 1% garlic (T2). The findings revealed that broiler fed basal diet with supplementation of 1% garlic powder had helped as a growth promoter contributing to the better growth performance, feed efficiency and higher benefit: cost ratio. Thus, addition of 1% garlic powder can be safely recommended as a growth promoter in broilers.

Abstract The objective of this study was to investigate the effects of dietary botanical supplementation on growth performance and frequency of diarrhea of weaned piglets experimentally infected with a pathogenic F18 Escherichia coli (E. coli). Sixty weaned piglets (around 21 days old; 7.15 ± 0.97 kg) were individually housed and randomly allotted to one of five dietary treatments (n = 12): negative control (NC), positive control (PC), high dose of botanicals blend 1 (BB1, 100 ppm), low dose of botanicals blend 2 (BB2, 50 ppm), and high dose of botanicals blend 2 (BB2, 100 ppm). The experiment lasted 28 days: from day -7 to +21 relative to E. coli inoculation. All piglets except the pigs in the NC group were orally inoculated with F18 E. coli (1010 cfu per dose, 3 doses) for 3 consecutive days. Growth performance was recorded throughout the experiment and diarrhea scores were recorded daily. Data were analyzed by ANOVA using PROC MIXED of SAS with a randomized complete block design. E. coli challenge reduced (P &lt; 0.05) pig body weight and growth rate throughout the experiment. Pigs supplemented with high dose BB1 or BB2 tended (P &lt; 0.10) to have greater body weight (19.52 and 19.10 vs. 18.00 kg) on d 21 PI and greater average daily gain from d 0 to 21 PI (554 and 557 vs. 515 g/d) than PC. No differences were observed in pig performance between high dose BB1 or BB2 in comparison with NC. Supplementation of high dose BB1 or BB2 also reduced (P &lt; 0.05) frequency and severity of diarrhea of challenged pigs during the entire experimental period. In conclusion, dietary supplementation of botanicals reduced diarrhea and tended to improve growth performance of weaned pigs infected with E. coli.
