| Sumari: | An experiment was conducted to assess the nutritive
value of prawn waste for growth in Large White Yorkshire pigs.
Thirty female pigs with an average body weight of
31.4 kg were divided into three equal groups as uniformly as
possible with regard to age and body weight. The three groups of
pigs were maintained on three different experimental diets viz., Tl
control standard grower (16 per cent CP) and finisher ration (14
per cent CP), T2 - 25 per cent of total protein in Tl replaced by
protein from prawn waste and T 3 - 50 per cent of total protein in
T 1 replaced by protein from prawn waste.
The average daily gain recorded for the three groups
T1, T2 and T3 were 385.5, 393.3 and 381.1 g respectively. The
cumulative feed conversion efficiencies were 4.87, 4.73 and 4.89 for
the groups T1, T2 and T3 respectively.
The digestibility coefficients of nutrients were
significantly higher in T2 for dry matter (p<0.05) and crude
protein (p<O.Ol). Digestibility coefficient of nitrogen free extract
was found significantly higher (p<O.Ol) for T3 than those for Tl
and T2. The digestibility coefficients of crude fibre and ether
extract were almost similar for all the three groups.
Study of the carcass characteristics revealed that
dressing percentage, carcass length, back fat thickness, loin eye
area and ham weight were not significantly influenced by the
inclusion of prawn waste at different levels.
The cost of feed per kg weight gain of animals in
different treatments Tl and T2 and T3 were Rs. 29.95, 23.84 and
21.18 respectively.
The above results indicate that, prawn waste can be
used economically to replace the protein of the grower and finisher
rations for pigs up to 50 per cent level.
