viz., Kochi, Kodungalloor and Kozhikode contained on an
average 21.9 per cent dry matter, 37.6 per cent crude protein,
24.4 per cent total ash, 17.4 per cent acid detergent fibre,
8.91 per cent calcium and 1.72 per cent phosphorus. Prawn
waste procured from Kochi area had higher dry matter, total
ash, acid detergent fibre, calcium and phosphorus and less of
crude protein. The results of in situ degradability studies
carried out in three rumen fistulated cows indicated that the
dry matter and crude protein degradabilities of prawn waste
ranged from 35 to 45 and 44 to 56 per cent respectively.
Prawn waste from Kochi area had lower (P<0.0l) dry matter and
crude protein degradabilities than the other two areas.
Metabolism trials conducted in adult, non-producing cattle
using standard concentrate mixtures containing 0, 10 or 20 per
cent prawn waste registered in the ration digestibility
coefficients to the extent of 53 to 56, 52 to 55, 63 to 67, 61
to 64 and 60 to 63 per cent for dry matter, crude protein,
ether extract, crude fibre and nitrogen free extract
respectively. There was no significant difference (P<0.05) in
the digestibilities of nutrients in the three treatments. The
animals on all the rations were on positive nitrogen balance.
It is inferred that prawn waste can be safely and economically
incorporated upto 20 per cent level in the concentrate
mixtures of adult non-producing cattle.
