| This study was designed to investigate the effect of vitamin E supplementation on vitamin E depots and immune responses in weaned pigs after an E. coli inoculation. The design was a 2×2 factorial with vitamin E supplementation (150 mg/kg RRR-α-tocopheryl acetate versus a control diet containing 60 mg all-rac-α-tocopheryl acetate) and E. coli 0 149 inoculation (inoculation of 1×108 CFU on day 2 and 3 after weaning versus inoculation of vehicle). The pigs were housed individually during the experiment which lasted for 10 days from weaning at 7 weeks of age. Blood was sampled on day 1 (day of weaning) and 9 of the experiment, and serum was analyzed for α-tocopherol concentration. On day 10 of the experiment, pigs were killed and samples of liver, heart,... |

| Four dietary factors (ad libitum versus feed restriction, control versus protein restriction at ad libitum feeding, control versus inclusion of lupine as a protein source at ad libitum feeding, and control versus extra vitamin E at ad libitum feeding) were tested in four separate experiments for the effect on diarrhoea. To introduce a diarrhoea-like condition, half of the piglets were challenged with an inoculation of an E. coli O 149 dose of 1 x 108 colony forming units on day two and three after weaning (day of weaning = day one). All piglets were susceptible since the dams were tested mono-zygotic susceptible to the attachment site of E. coli O 149 in the intestines. Each of the four experiments included 32 piglets from 4 sows. The design was 2 x 2... |

| Virkningen af ekstra E vitamin på fravænningsdiarré blev undersøgt i tre økologiske svinebesætninger. Ved fravænning blev grisene i disse besætninger delt i to hold hvoraf det ene hold fik ekstra naturligt E vitamin i foderet (100 mg/kg), mens kontrolholdet fik samme foderblanding uden ekstra E vitamin. Foderblandingerne i de tre besætninger havde i forvejen et ret højt E vitamin indhold (55-150 mg alfa-tocoferol pr. kg). Gødningskarakter og vægt blev registeret på fravænningsdagen samt 5 dage og ca. 5 uger efter fravænning. Der var stor forskel i graden af diarré i de tre besætninger, men hverken i to problemfrie besætninger eller i en besætning med udbredt fravænningsdiarré havde den ekstra E vitamin nogen virkning på tilvækst og diarré.... |
