The effects of partial neutralization with sodium bicarbonate or ammonia and the feeding of blood meal on the voluntary intake of a whole-crop barley silage by sheep
Published online by Cambridge University Press: 02 September 2010
Summary
Silage made from a whole crop of barley was offered to sheep without neutralization or after partial neutralization to pH 5·4 to 5·5 with sodium bicarbonate or ammonia. In a further treatment the un-neutralized silage was supplemented with blood meal administered each day as a drench. Total organic-matter intake and nitrogen retention were significantly higher for the sheep receiving the blood meal supplement than for any of the other treatments, which did not differ significantly one from another. It is suggested that the intake of the un-supplemented silage was limited by a low uptake of amino acids from the intestine.
