The effect of Bacillus natto in feed on the sheep red blood cell antibody response in chickens.
Chickens fed 10(6) or 10(7) of Bacillus natto strain BN/g of diet from hatching through 15 or 30 days of age showed an increase in ability to produce hemagglutinating antibody titer as determined by intravenous injection of sheep red blood cells, whereas no increase in antibody production ability was observed in the chickens fed 10(7) of BN/g of diet from hatching through 10 days of age.
