Vitamin E Supplementation

The present study was carried out to investigate the effect of dietary vitamin E on growth performance, cellular immunity, carcass characteristics, and meat quality in geese. Sixty-four one-day-old male geese were selected from 1200 goose chicks with the same average body weight (92.5 ± 2.5 g) and subjected to two treatments (basal diet or control and basal diet plus 120 mg/kg vitamin E supplement) with 4 replicates (8 geese per replicate) for 8 weeks. After slaughter, goose meat was aerobically packed in polyethylene packages and stored at 4 °C for 9 days. The results showed that vitamin E supplementation improved the growth performance, carcass yield percentage, and immune response of goose (p < 0.05). The addition of vitamin E in the diet significantly increased the protein and fat content of goose meat but decreased the moisture and ash content with respect to those obtained from the control diet. During storage, meat from the vitamin E treatment showed higher phenolic content and lower thiobarbituric acid reactive substances (TBARSs) and total volatile nitrogen (TVB-N) values than those from the control treatment. Vitamin E supplementation increased the saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), and polyunsaturated fatty acids (PUFAs) in goose meat. However, goose meat supplemented with vitamin E displayed a significantly (p < 0.05) higher PUFA/SFA ratio than those of the control group. Based on the results, it was concluded that vitamin E could be used to improve the growth performance of goose, the meat composition in terms of the protein and fat content, the nutritional value in terms of the fatty acid composition, and the shelf life.

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.
