| Summary: | An investigation was carried out to assess the influence
of monensin supplementation in complete rations for kids.
Thirty Malabari kids of three to four months of age were
divided randomly into three equal groups (I, 11 and Ill). The
animals were maintained on isoproteimic and isocaloric
complete rations A, Band C containing eight, twelve and
sixteen per cent crude fibre respectively for a period of
13 weeks'" (91 days). The rations were supplemented with
monensin at the rate of 20 mg/kg.
The weight gained by animals during the experimental
period was highest in group I followed by groups 11 and III in
the descending order, groups I and 11 showing significantly
higher gains (P<O.Ol) than group Ill. This is suggestive of
the positive influence of monensin in rations containing lower
levels of crude fibre.
Monensin did not appear to have any effect on body
measurements viz., body length, chest girth and height at
withers.
The average daily dry matter (DM) intake of animals in
group I was significantly higher (P<O.05) than group Ill, but
there was no significant difference (P>0.05) in DM intake per
100 kg body weight between the three groups.
There was no significant difference (P>0.05) in weekly
feed conversion efficiency values between the three groups.
The cost of production per kilogram gain increased
linearly with increase in the level of crude fibre in the
ration.
The digestibility coefficients of dry matter, organic
matter, crude protein, ether extract and nitrogen free extract
did not differ significantly (P>0.05) between the three
groups. However, the digestibility coefficient of crude fibre
was significantly lower (P<0.05) in group I when compared to
groups 11 and Ill.

The gross profit declined linearly with increase in the

From an overall evaluation of the results obtained during
the course of the present investigation, it can be inferred
that, supplementing monensin in low fibre complete rations
improves growth and feed efficiency in kids reared under
intensive system of management. The gross profit that can be
expected from a kid of group I fed on ration A works out to
Rs.254 over a period of 90 days.
