This experiment was conducted to investigate
the effects of treatment of wheat straw with aqueous ammonia
on its digestibility and feed intake and weight gain of
beef ca tt/e fed two /eve/ of concentrate mixture.
About five tones ~eat straw stack treated with 40 g
aqueous ammonia contains 25 % NH3 per kg straw for 30
daysalter co vering the stack with plasüc sheet.
The digesübilities of untreated and treated straw was determined
with tour Merino ram s. The digesübilities of dry mat- . ter, crude protein, crude tibre, organic matter were 4Z 74,
58.80, 58.83 and 49.22 % for untreated straw and 49.59,
73.42, 63.35, 52.92 % for treated straw, respectively. . In the feeding experiment, 28 bul/s were allocated to fovr
groups each of 7 bul/s. Two /eve/ of concentrate mixture and
two straw (treated and untreated) were given with a 2x2 factorial
arrangement. The ammonia treatment decreased straw intake.
No differences in the live weights gain were found
among the groups.
