silk worm pupae meal, a by-product from sericulture industry,
on growth, feed conversion efficiency and economics of
production in growing pigs.
Twenty seven weaned Large White Yorkshire female piglets
wi th an average body weight of 16 kg were selected from
university Pig Breeding Farm, Mannuthy and were divided into
three groups of nine piglets each, as uniformly as possible
with regard to their age and body weight. The piglets were
then randomly allotted to three pens to form three replicates
per treatment. The three groups of piglets were maintained
for 90 days on three isonitrogenous and isocaloric diets T1,
T2 and T) in which protein from unsalted dried fish was
replaced by silk worm pupae meal at 0, 50 and 100 per cent
level.
The animals maintained under the three dietary treatments
T1, T2 and TJ had almost similar growth rate (P>0.05) with a
cumulative average daily gain of 481.4, 510.1 and 495.7g.
respectively.
The total feed intakes of the animals in different groups
were almost similar. There was no significant difference
(P>0.05) in cumulative feed conversion efficiency between the
II ~b?
groups, the values being 3.78, 3.63 and 3.62, respectively,
for animals in the dietary treatments Tl, T2 and T).
The digestibility coefficients of nutrients except that
of ether extract, were slightly higher for the control ration
compared to those with silk worm pupae meal.
The cost of production per kilogram live weight gain of
pigs maintained on the three dietary treatments, T1, T2 and T)
were Rs. 31.46, 29.19 and 28.20 respectively. Though there
was a slight decrease in the cost of production due to
incorporation of silk worm pupae meal in place of unsalted
dried fish in swine ration, the difference was non
signif icant (P>O. 05) .
The above results indicate that silk worm pupae meal can
be effectively included in the diets of growing pigs without
affecting growth, feed conversion efficiency and the cost of
production.
