Ninety standard dark male minks (8 wk of age) were used to investigate the effects of vitamin E (VE) supplementation on growth performance, antioxidative status, and some immunological blood parameters. The dietary treatments included a basal diet (containing 20.86 mg kg−1VE) supplemented with 0 (control), 50, 100, 200, 400, or 800 mg kg−1VE. The results showed that VE supplementation of 200–400 mg kg−1increased (P < 0.05) the body weight, average daily feed intake, average daily gain, and gain to feed ratio of the mink from days 1 to 30. At days 30 and 60, the minks fed diets supplemented with 400 mg kg−1VE had higher (P < 0.05) concentrations of serum superoxide dismutase, glutathione peroxidase, and catalase than either the control or the VE50 groups but had activity levels similar to those of the VE200 and VE800 groups. Feeding a high dose of VE (400–800 mg kg−1diet) resulted in a significant increase in the concentrations of α-tocopherol and a reduction in the reactive oxygen species content in the serum. Vitamin E supplementation of 200–400 mg kg−1increased (P < 0.05) the concentrations of immunoglobulin G, interleukin-2, and soluble CD4/soluble CD8and decreased (P < 0.05) the content of soluble CD8in the serum. Overall, the suitable level of VE supplementation was found to be 200–400 mg kg−1diet for growing mink.

Egg Storage

Two trials were conducted to investigate the effects of maternal and progeny dietary vitamin E (VE) supplementation on the growth performance and antioxidant status of offspring before and after egg storage. A total of 576 75-week-old Ross 308 breeder hens were assigned to three dietary VE treatments (100, 200, and 400 mg/kg) with 6 replicates of 32 hens for 12 weeks. Two trials were conducted with offspring hatched from eggs laid at weeks 9 and 12 of breeder feeding trial, respectively. Trial 1 was conducted by a 3 × 2 factorial arrangement of treatments with three levels of maternal dietary VE (100, 200, and 400 mg/kg) and two levels of progeny dietary VE (0 and 35 mg/kg). Trial 2 was conducted with three maternal dietary VE treatment (100, 200, and 400 mg/kg), and chicks were hatched from eggs stored for 14 d and received the same progeny diet with no addition of VE. Results showed that in trial 1, maternal (100, 200, and 400 mg/kg) and progeny (0 and 35 mg/kg) dietary VE supplementation did not affect the growth performance of offspring hatched from unstored eggs (p > 0.05). In trial 2, in the case of long-term egg storage, maternal dietary VE supplementation of 200 and 400 mg/kg increased the body weight (BW) of 21- and 42-d-old offspring and the body weight gain (BWG) of offspring from 1 to 21 d (p < 0.05), and decreased the feed conversion ratio (FCR) of offspring from 1 to 21 d (p < 0.05) compared to 100 mg/kg VE. As the maternal dietary VE levels increased, the liver and serum antioxidant status of offspring enhanced (p < 0.05). In conclusion, maternal dietary VE supplementation of 200 or 400 mg/kg could improve the growth performance and anti-oxidant status of offspring hatched from stored eggs, but not for that of offspring hatched from unstored eggs. The suitable VE level for the broiler breeder diet was 400 mg/kg in the case of long-term egg storage.

This experiment aimed to investigate effects of the different dietary levels of vitamin E (VE) on the growth performance, immunity and antioxidant capacity of goslings. A total of 240 1-day-old, male Jiangnan white goslings were selected and randomly divided into 6 groups. Each treatment included five replicates. The basal diet was supplemented with 6 concentrations of VE (0, 12, 24, 36, 48 and 60 mg DL-α-tocopherol acetate/kg). The results were as follows: (1) The α-tocopherol content in the serum and liver of goslings increased linearly as supplemental VE increased in diet (p < 0.05). (2) The body weight (BW) and average daily gain (ADG) increased quadratically with increasing dietary VE supplementation (p < 0.05). Dietary VE supplementation could significantly reduce the feed/gain ratio (F/G) (p < 0.05). (3) Dietary supplementation with VE could significantly improve the contents of immunoglobulin A (IgA) and immunoglobulin G (IgG) in the serum of the goslings (p < 0.05). The content of interferon-γ (IFN-γ) in the serum was significantly reduced with VE supplementation (p < 0.05). (4) Dietary supplementation with VE could significantly improve serum and liver catalase (CAT), superoxide dismutase (SOD) activities and liver total antioxidant capacity (T-AOC) (p < 0.05); Serum and liver MDA contents were significantly reduced with VE supplementation (p < 0.05). In summary, dietary supplementation with VE could improve growth performance, immunity and antioxidant capacity. Based on broken-line regression analysis, the dietary VE supplementation level for ADG was 12.51 mg/kg, but higher supplementation level should be considered to improve immunity and antioxidant capacity.

Abstract The objective of this study was to evaluate the use of dietary vitamin E (VitE) and polyphenols on growth and oxidative status of weaned piglets fed peroxidized lipids. Pigs (n = 192; 21-d of age; 6.62±1.04 kg BW) were assigned within sex and weight blocks to a 2x3 factorial arrangement using 48 pens (4 pigs/pen; 8 replications/treatment). Factors consisted of lipid peroxidation (6% human-grade soybean oil or 6% peroxidized soybean oil), and antioxidant supplementation (control diet containing 25 IU/kg dl-α-tocopherol-acetate; control with 200 IU/kg additional dl-α-tocopherol-acetate; or control with 400 mg/kg polyphenols). Peroxidation was accomplished by heating control oil at 80°C with constant air flow at 50 L/min for 12 d (initial peroxide, anisidine value, hexanal, and 2,4-decadienal concentrations were 4.1 vs. 141.6 meq/kg, 1.7 vs. 106, &lt; 5 vs. 99 mg/kg, and 8 vs. 720 mg/kg for control and peroxidized oil, respectively). Diets were fed in 2 phases (14 and 21 days). Overall, peroxidized lipids decreased (P &lt; 0.001) BW (23.16 vs. 18.74 kg), ADG (473 vs. 346 g/day), ADFI (658 vs. 535 g/day) and G:F (719 vs. 647 g/kg). Lipid peroxidation decreased serum vitamin E (P &lt; 0.001) and this decrease was larger on d35 (1.82 vs. 0.81 mg/kg) than d14 (1.95 vs. 1.38 mg/kg). Supplemental VitE, but not polyphenols, increased (P &lt; 0.002) serum vitamin E by 84 and 22%, for control and peroxidized diets, respectively (interaction, P = 0.001). Serum malondialdehyde decreased (P &lt; 0.001) with peroxidation on d14, but not d35 and protein carbonyl increased (P &lt; 0.001) with peroxidation on d35, but not d14. Serum 8-hydroxydeoxyguanosine was not affected (P &gt; 0.05). Total antioxidant capacity decreased with peroxidation (P &lt; 0.001) and increased with VitE (P = 0.065) and polyphenols (P = 0.046) in the control oil diet only. Peroxidized lipids reduced growth performance, which could not be corrected with supplemental vitamin E or polyphenols in the diet.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.
