Abstract Environmental or metabolic heat can increase oxidative stress in sows and may impact suckling pig growth; yeast cell- and oil-based products are used to alleviate oxidative stress. A study was conducted to assess yeast cell and mint oil supplementation in sow lactation diets on sow anti-oxidant status and offspring performance to weaning. A total of 45 sows and gilts (240.7 ± 38.5 kg BW) were assigned to one of 4 diets: Control diet (CON), control + yeast cell at 0.2% (YC), control + mint oil at 10 ppm (MO), and control + yeast cell and mint oil (YCMO). Diets were provided from d 110 of gestation through weaning (21 ± 4 d). Variables evaluated were: sow and piglet growth, litter characteristics at birth, colostrum and milk oxidative status, sow feed intake. Data analyzed as randomized complete block with sow as experimental unit and Tukey’s adjustment as means separation test. There was no effect of maternal diet on sow BW (204.52 ± 43.5 kg) at weaning, piglet birth weight (1.44 ± 0.96 kg), litter size (13.09 ± 6 pig/sow) or sow feed intake (6.32 ± 3.05 kg). Piglets from CON females had lesser gain (P < 0.05) compared with the other groups during the suckling phase (0.23, 0.24, 0.24, and 0.24 ± 0.005 kg in CON, YC, MO, and YCMO group, respectively). Superoxide dismutase activity in sow serum (d110 and weaning), colostrum, and milk was not different among diets and was 39, 59, 45, and 10% lower at weaning than d 110 in CON, YC, MO, and YCMO sows, respectively. Milk glutathione content tended to be lower (P < 0.10) in MO than YCMO sows with CON and YC intermediate (15.2, 32.0, 20.6, and 21.1 U/ml), respectively. Overall, inclusion of yeast cell or mint oil enhanced piglet growth, which may be related to lower sow antioxidant status.

Abstract Times of high metabolic activity can lead to increased incidence of oxidative stress in gestating and lactating sows which may impact suckling piglet performance. Identifying products that could help alleviate this stress would be beneficial. A study assessed yeast cell, mint oil, and ɣ-tocopherol supplementation in gestation and lactation diets on sow antioxidant status and offspring performance to weaning. A total of 53 sows and gilts (206.2 ± 35.3 kg at breeding) were assigned to one of 4 diet regimens: Control (CON), control + yeast cell at 0.15% (YC), control + mint oil at 10 ppm (MO), and control + ɣ-tocopherol at 200 ppm (GT). Diets were provided from breeding through weaning (lactation day 21 ± 2). Control diets were formulated to meet nutrient requirements in gestation (3279 kcal ME/kg, 0.63% SID Lys) and lactation (3279 kcal ME/kg, 1.06% SID Lys). Yeast cell, mint oil and ɣ-tocopherol were added as a top dress once daily. Sow variables evaluated were weight at beginning and end of each period, feed intake, litter characteristics at birth, and antioxidant status in serum, colostrum and milk. Piglet growth during suckling was determined. Data were analyzed as randomized complete block and Tukey’s adjustment as means separation test. Maternal diet had minimal impact on gestation or lactation feed intake or sow body weight. There was no effect on litter size or piglet birth weight. Piglets from GT-fed sows tended to be heavier at weaning than YC piglets due to differences in daily gain. Glutathione content in colostrum and d14 milk samples did not differ by maternal treatment. D14 milk Glutathione content was 40%, 59%, 62%, and 51% greater in CON, YC, MO, and GT sows, respectively, compared to colostrum. No difference in superoxide dismutase content in serum and d14 milk observed. Inclusion of ɣ-tocopherol in sow gestation and lactation diets enhanced suckling piglet growth; connection to sow antioxidant status remains unclear.

Abstract Social and dietary stress at weaning can increase oxidative stress in piglets and impact performance during the early post-wean period. A study was conducted to assess yeast cell and mint oil supplementation during suckling and post-wean periods on offspring growth performance. A total of 481 piglets (6.25 ± 3.35 kg BW) from 45 sows were randomly allotted to pens balanced by weight and litter (6-8 pigs/pen) within maternal diet. Pens of pigs received the same dietary treatment as the sow during the suckling phase: control diet (CON), control + yeast cell at 0.2% (YC), control + mint oil at 10 ppm (MO), and control + yeast cell and mint oil (YCMO) for 35 d post-wean in a 4-phase feeding regimen (phase 1, d0-6; phase 2, d7-13; phase 3, d14-19; phase 4, d20-35). Performance was analyzed as randomized complete block with pen as experimental unit and Tukey’s adjustment as means separation test. Piglets from YC sows were heavier (P < 0.05) than CON with MO and YCMO intermediate at weaning (6.9, 6.5, 6.7 and 6.6 ± 0.2 kg, respectively) and day 6 post-wean (7.12, 6.68, 7.01, and 6.75 ± 0.09 kg, respectively) and no difference among groups at day 13 (9.1 ± 0.16 kg), 19 (11.3 ± 0.19 kg) and 35 (19.7 ± 0.35 kg). Overall, daily gain was greater (P < 0.05) CON-fed pigs than YCMO pigs (0.40, 0.39, 0.38, 0.37 ± 0.01 g/d in CON, YC, MO, and YCMO, respectively). Overall feed intake was greater (P < 0.05) for YCMO than MO resulting in lower (P < 0.05) gain:feed in YCMO-fed pigs vs CON and MO with YC-fed pigs intermediate (0.538 vs 0.617, 0.621, and 0.585, respectively). Exposure to yeast cell or mint oil during the suckling and early post-wean periods provided some benefit to offspring performance.

Abstract Weaning is a period of pig growth associated with increased incidence of oxidative stress which can impact post-weaning performance. Inclusion of feed additives with antioxidant activity in sow diets has been reported to improve offspring growth beyond the suckling phase. A study assessed yeast cell, mint oil, and ɣ-tocopherol supplementation in sow gestation and lactation diets has on offspring post-weaning performance. A total of 605 piglets (6.14 ± 2.53 kg BW) from 53 sows were randomly allotted to 62 pens, balanced by weight and litter within maternal diet [Control diet (CON), control + yeast cell at 0.15% (YC), control + mint oil at 10 ppm (MO), and control + ɣ-tocopherol at 200 ppm (GT)]. Pens of pigs were given a common diet for 126 d post-wean in a 9-phase feeding regimen. After d29 post-wean, performance of pigs deemed light (&lt; 5.10 kg) and heavy (&gt;7.25 kg) at weaning were followed to d126. Performance was analyzed as randomized complete block with pen as experimental unit and Tukey’s adjustment as means separation test. Pigs from CON sows tended to be lighter pigs from all other treatment groups at weaning and d29 post-wean due to differences in daily gain. Lightweight MO and GT pigs had a heavier weight at d42 (P=0.002) than CON and YC pigs (16.8, 16.7, 19.3, and 19.9 ± 0.77 kg in CON, YC, MO, and GT, respectively). At d70 post-wean, GT pigs tended to be heavier than CON pigs, with YC and MO intermediate. Lightweight pigs from MO sows had greater gain (P=0.04) during the finishing period than all other treatment groups, with GT pigs gaining less. There were no detectable differences in BW during the finishing phase among treatments in heavyweight pigs, however, CON pigs tended (P=0.07) to gain the least. Exposure to mint oil and ɣ-tocopherol during the prenatal and suckling period may provide lasting benefits to light-weight pigs post-wean.

Times of high metabolic activity in gestation and lactation, as well as periods of stress at weaning, can lead to greater incidences of oxidative stress in the dam and offspring during the suckling and postweaning period. Oxidative stress is an imbalance between prooxidant molecules and the antioxidant defense system that can negatively impact growth and/or reproductive performance. The objective of this research was to evaluate the effectiveness of whole yeast cell, peppermint oil, and ɤ-tocopherol in gestation and lactation on maternal oxidative status and offspring growth from birth to market. In study 1, 45 sows and gilts were assigned to one of four diets [control diet (CON), control + whole yeast cell (YC), control + mint oil top dress (MO), and control + yeast cell and mint oil top dress (YCMO)] provided from d110 of gestation through to weaning. A total of 481 weaned offspring were randomly allotted to pens balanced by weight and litter within maternal treatment and received the same dietary treatment as the sow for 35 days postwean in a four-phase feeding regimen. In study 2, 53 sows and gilts were allotted to four diet regimens similar to study 1 [CON, YC, MO, and control + ɤ-tocopherol (GT)] from d5 postbreeding to weaning. At weaning, 605 piglets were randomly allotted to pens, balanced by weight and litter within maternal treatment and fed a common diet for 126 days postwean in a nine-phase feeding regimen. Maternal dietary treatment did not impact sow body weight, piglet birth weight, and litter size in either study. In study 1, piglets from YC sows were heavier (p &lt; 0.05) at weaning than CON animals. In the postwean period, overall daily gain was greater (p &lt; 0.05) for CON-fed pigs than YCMO pigs, with overall feed intake greater (p &lt; 0.05) for YCMO- than MO-fed pigs, resulting in lower (p &lt; 0.05) Gain to Feed (G:F) in YCMO-fed pigs. In study 1, glutathione content in milk tended to be lower (p &lt; 0.10) in MO than in YCMO sows. In study 2, piglets from GT-fed sows tended to be heavier (p &lt; 0.10) at weaning than YC piglets. Lightweight pigs from CON sows tended to be lighter (p &lt; 0.10) than pigs from all other treatment groups at weaning and day (d) 29 postwean. Lightweight MO and GT pigs were heavier at d42 (p &lt; 0.05) than CON and YC pigs. At d70 postwean, GT pigs tended to be heavier than CON pigs. Lightweight MO pigs had greater gain (p &lt; 0.05) during the finishing period than all other treatment groups. With respect to sow oxidative status in study 2, glutathione content in colostrum and d4 and 14 milk samples did not differ by maternal treatment. Superoxide dismutase activity in sow sera, colostrum, and milk did not differ between diets in either study. Whole yeast cell and ɤ-tocopherol supplementation in sow lactation diets resulted in heavier offspring. However, pre- and postnatal exposure to mint oil benefited lightweight pigs up to market weight.

Abstract Ingestion of mycotoxins can result in many problems, including decreased growth rates and immune suppression. The present study aimed to evaluate the impact of the supplementation of a mycotoxin deactivator composed by adsorbent clay minerals, inactivated fermentation extracts of Saccharomyces cerevisiae, blend of antioxidants, organic acids and botanicals in diets containing added mycotoxins for nursery pigs on their performance and antioxidant status. Ninety pigs weaned with 24 days of age (7.12 ± 0.68 kg of BW) were used. Pigs were housed in pens of 3 animals each according to body weight, litter origin and sex. The dietary treatments consisted of feeding the pigs with: a standard control diet as negative control (NC; mycotoxin levels at accepted regulatory Brazilian Ministry of Agriculture standards Deoxynivalenol (DON): &lt;100 ug/ kg; Zearalenone (ZEA): &lt;20 ug/ kg Fumonisins (FB): &lt;1 mg/ kg); the standard diet added with mycotoxins to reach a low contamination level considered as positive low (PCL-; DON: 900 ug/ kg; ZEA: 100 ug/ kg; FB: 5,000 ug/ kg) without deactivator; a positive low added the deactivator at an inclusion rate of 1 kg/ ton (PCL+); the standard diet added with mycotoxins to reach a high contamination level considered as positive high (PCH-; DON: 4,500 ug/ kg; ZEA: 500 ug/ kg; FB: 18,000 ug/ kg) without the deactivator; and a positive high added the deactivator at an inclusion rate of 5 kg/ ton (PCH+). Pigs were individually weighed at the beginning and at the end of each phase and feed intake recorded based on daily pen intake during the experiment. On d 7, 19, 34 and 43 post-weaning blood samples were drawn for antioxidant analyses. Antioxidant enzymes (glutathione peroxidase (GPx) and total superoxide dismutase (TSOD)), vitamins (Vit A, E, and C), and malondialdehyde (MDA)) were evaluated in erythrocyte and plasma samples. Pigs challenged with mycotoxins presented lower performance traits, decrease in the efficiency of central antioxidant systems (↓GPx, ↓TSOD, ↓Vit A, ↓Vit E and ↓Vit C) and a higher oxidative damage to lipids (↑MDA) when compared to the control and deactivator associated treatments. Our findings showed that the use of a mycotoxin deactivator can mitigate the negative impacts on performance and oxidative stress when animals are subjected to diets contaminated by different levels of mycotoxins.

To determine how feeding linseed meal (LSM) during gestation influences litter size, placental weight, and piglet growth, sows (n = 30) received a phytoestrogen-free Control diet throughout gestation; 12.5% LSM diet throughout gestation (LSM114); or 12.5% LSM diet from day 1 to day 15 of gestation and control diet until parturition (LSM15). Maternal diet did not affect birth weight, placental weight, or postnatal growth. The number of fully formed piglets was increased (P = 0.05) in LSM15 sows compared with Control and LSM114 sows (13.5 vs. 10.1 and 11.6 ± 1.0, respectively). Feeding LSM during the first 2 wk after breeding may enhance litter size.

Short Time

The oxidation and antioxidant status of serum are often determined in serum samples which have been frozen for some time. The oxidative stress process is prone to fast alterations in the sample because of the possible instability of the reactants. Here one oxidation assay (ROM) and three antioxidant assays (FRAP, TAS, and BAP) have been tested on their performance and stability at short-time storage. The most commonly used temperatures for storage and handling of serum samples (+4 and +20°C) were selected. In three short-term studies in which the storage time varied between 3 and 48 hrs the performance of these assays were tested on human serum samples. The general conclusion is that most assays performed well and gave stable results during 2 days of storage of the samples at both temperatures. Only the FRAP and TAS assays showed a small deviation at some storage conditions. In conclusion, handling of serum samples at +4 and +20°C during short-time periods did not affect the quality and performance of the oxidation and antioxidant assays during day-to-day analyses.

An experiment was conducted to compare the haematology and some serum constituents and performance of broilers fed diets containing improved (addition of anti-microbial and anti-oxidant) locally produced natural vitamin premix (LPNVP), LPNVP without improvement and commercial vitamin premix (CVMP). Haematology of the birds was not affected by the dietary treatments. However, red blood cell (RBC) count was significantly high (P<0.05) for the birds fed diet containing improved LPNVP The haemoglobin, PCK, RBC and WBC values observed for birds fed improved LPNVP were 13 gm%, 32%, 246 x 1012/L and 3.1 x 1010/L respectively. Serological parameters observed in the study were not significantly different (P>0,.05) for all the dietary conditions studied. Birds fed diet containing improved LPNVP also recorded comparable serum components to control diet containing the commercial vitamin/’mineral premix. Serum calcium, phosphorus, glucose, ureate, creatinine and total protein observed for birds fed diet containing improved LPNVP were 2.32%, 0.70%, 3.60Mmo/L, 2.9Mmo/L, 0.25Mmol/L, 58Mmol/L and 66g/100ml respectively. Feed intake, weight gain and feed utilization were similar (P>0.05) for the various dietary treatments. Birds fed improved LPNVP based diets tended to record better feed intake than did the control birds on CVMP based diets and unimproved LPNVP. Generally, improvement of LPNVP tended to give better performance of broilers than did other dietary treatments.

Abstract. This study was carried out to evaluate the effects of dietary supplementation of purslane powder (PP) on performance, blood indices, and antioxidant status in broilers with triiodothyronine (T3)-induced ascites. In total, 240 one-day-old male broiler chicks (Ross 308) were randomly assigned to four treatments, with four replicates per treatment and 15 birds per replicate. The experimental diets included (i) a control diet, (ii) a control diet plus 1.5 mg kg−1 of T3 (T3 diet), (iii) a T3 diet with the addition of 1.5 g kg−1 of PP, and (iv) a T3 diet with the addition of 3 g kg−1 of PP. Feed intake and body weight were measured at 10, 24, 39, and 49 days of experiment. Blood and liver samples were collected from two birds in each replicate at 24 and 49 days of experiment. The T3-treated birds had higher (P < 0. 05) right ventricle to total ventricle (RV ∕ TV) ratio and mortality due to ascites compared with the control. In addition, during the entire experimental period (0 to 49 days of experiment) the T3-treated birds had lower (P < 0. 05) feed intake, body weight gain, and production efficiency index and higher (P < 0. 05) feed conversion ratio compared with the control. Dietary supplementation of PP reduced (P < 0. 05) mortality due to ascites and RV ∕ TV ratio, while the production efficiency index was increased (P < 0. 05) by the addition of PP to the diet. The T3-treated birds had higher (P < 0. 05) red blood cell counts, hematocrit percentage, and hemoglobin concentration compared with the control at 24 and 49 days of experiment. Dietary supplementation of PP substantially alleviated (P < 0. 05) the negative effects of T3 on hematocrit and hemoglobin values at both 24 and 49 days of experiment and on red blood cells counts at 49 days of experiment. The T3 birds showed an increase (P < 0. 05) in activities of lactate dehydrogenase, alanine aminotransferase, and aspartate aminotransferase at 49 days of experiment. However, the detrimental effect of T3 on alanine aminotransferase activity was attenuated (P < 0. 05) by dietary supplementation of PP. The plasma and liver activities of superoxide dismutase, catalase, and glutathione peroxidase were lower (P < 0. 05) in T3-treated birds compared with the control at 24 and 49 days of experiment, whereas malondialdehyde concentrations were elevated (P < 0. 05) by dietary T3 administration. Dietary supplementation of PP, especially at 3 g kg−1, increased (P < 0. 05) the plasma and liver activities of antioxidant enzymes, and reduced (P < 0. 05) the plasma and liver concentrations of malondialdehyde near to the control levels. It is concluded that the supplementation of 3 g kg−1 of PP in diet improves oxidative status and reduces ascites incidence in broiler chickens without impairing their growth performance.

Abstract Dietary fat may impact energy intake and palatability of feed, and influence energy storage. The objective of this experiment was to test the hypothesis that including a blend of short, medium, and long chain fatty acids and triglycerides (R2 Feed Energy, Pleasant Hill, IA) in lactation diets will reduce pre-weaning mortality and increase litter weaning weight. On day 114 of gestation, dietary treatments were initiated: 1) Negative control diet and 3.2% of an all-vegetable oil blend, (Trt B); 2) Control diet with replacement of oil blend with 3.2% proprietary blend of short, medium, and long chain fatty acids and triglycerides (Trt R). Sows (n = 207; L02 Cross; PIC, Hendersonville, TN) were allotted to treatment based on body condition and parity. There were 88 parity 0 and 1 sows: 45 on TRT R and 43 on TRT B, and 119 parity 2 to 6 sows: 59 on TRT R and 60 on TRT B. Average sow parity was 2.85. Sows received 1.56 kg of their assigned diet twice per day prior to farrowing. After farrowing, sows were fed ad libitum with free access to water. Data on sow ADFI, litter weaning weight, and number of piglets weaned per sow were evaluated using PROC MIXED (SAS Institute Inc., Cary, NC). Compared with B, sows fed R consumed more feed (6.44 vs. 5.90 kg/d; P < 0.025). There was no difference in weaning weight (6.1 vs. 5.9kg; P > 0.10) or number weaned per litter (11.44 vs. 11.28; P > 0.10), for treatments R and B, respectively. There was no difference in sow body condition score after weaning (2.07 vs. 1.93; P = 0.18) for treatments R and B, respectively. The addition of R2 to sow lactation diets improved sow feed intake, but not piglet growth or number weaned.
