Dietary B Vitamin Needs of Pigs Experiencing a Moderate or High Level of Antigen Exposure Stahly, Tim Cook, Doug 2018-02-13T00:37:02.000 2020-07-02T06:59:45Z 2020-07-02T06:59:45Z Wed Jan 01 00:00:00 UTC 1997 2012-08-20 1997
dc.description.abstract <p>Pigs were reared via two management schemes to create a moderate and high level of antigen exposure in the pigs. In each antigen exposure group, pigs were self-fed one of five dietary concentrations of a group of five B vitamins (niacin, pantothenic acid, riboflavin, B12, and folacin) from 22 to 61 pounds body weight. Bioavailable concentrations of the vitamins equivalent to 70, 170, 270, 370, and 470% of the current estimated need (NRC, 1988) for 11 to 22 pound pigs were provided. Pigs experiencing a moderate versus high level of antigen exposure consumed more feed (+.54 lb/day) and gained more body weight (.32 lb/day) but required similar amounts of feed per unit of gain (-.03).</p> <p>Dietary B vitamin additions at concentrations above current estimated requirements (NRC, 1988) resulted in up to 21 and 19% faster body growth rates and 10 and 6% less feed required per unit of gain in pigs experiencing a moderate and high level of antigen exposure, respectively. Based on these data, dietary concentrations of one or more of the test B vitamin equivalent to 370% of the current estimated needs (NRC, 1988) are required to optimize rate and efficiency of growth in 20 to 60 pound pigs experiencing a moderate or high level of antigen exposure.</p>
