Abstract
An experiment was conducted to assess the effect of dietary incorporation
of ayurvedic pharmaceutic residues on growth performance of Malabari kids for a
period of three months. Four ayurvedic pharmaceutic residues, viz., dhanvantharam
kashayam, vilvadi lehyam, panchagavya gritham and kottamchukkadi thailam,
were tested in vitro by in vitro gas production technique (IVGPT) to estimate
metabolisable energy (ME), digestible organic matter (DOM) and in vitro
degradable nitrogen (IVDN) and were ranked on the basis of a six point scoring
system. Panchagavya gritham residue which obtained the highest aggregate score
was selected as the best ayurvedic pharmaceutic residue and was used for further in
vivo study.
Three isonitrogenous and isocaloric rations (24 per cent CP and 70 per cent
TDN), T1, T2 and T3 with 0, 10 and 20 per cent panchagavya gritham residue,
respectively, formulated as per BIS (2012) were fed to kids so as to meet the
requirements of ICAR feeding standards (ICAR 2013). Fifteen healthy Malabari
kids were selected and divided into three groups of five each and allotted randomly
to above three experimental rations and subjected to a feeding trial of 90 days
duration. Data on body weight gain, daily dry matter consumption, feed conversion
efficiency, digestibility coefficients of nutrients, haemato-biochemical parameters
and economics were estimated to evaluate the rations.
The average daily body weight gain and total average weight gain of kids
were 57.51, 67.47, 53.04 g per day and 5.18, 6.07, 4.77 kg, respectively in groups
T1, T2 and T3, with the values being significantly higher (P<0.01) in kids of T2 as
compared to those of T1 and T3 with T1 and T3 being similar (P>0.01). The average
daily dry matter intake was 0.39, 0.43 and 0.39 kg per day, for kids in groups, T1,
T2 and T3, which was similar (P>0.05). The average values of feed conversion
efficiency of kids fed on rations T1, T2 and T3, were 4.06, 3.42 and 4.04, with the
values being similar (P>0.05).
There was no significant (P>0.05) difference in digestibility coefficients of
nutrients except ether extract which was significantly higher (P<0.01) in T2 than
85
T1 and T3 with T1 and T3 being similar (P>0.01); NDF and ADF which were
significantly higher (P<0.01) in T2 and T3 than T1, with T2 and T3 being similar
(P>0.01). All the haemato-biochemical parameters were similar among the three
groups and the values were within the normal range for kids. The cost per kg body
weight gain was Rs. 157.53, 122.88 and 128.87 for kids in groups, T1, T2 and T3,
respectively.
An overall critical evaluation of the results obtained in the present study
revealed that kids in groups T2 and T3 fed on rations containing panchagavya
gritham residue at 10 and 20 per cent level, respectively had similar DMI,
fortnightly body weight, FCE, haemato-biochemical parameters, digestibility
coefficients of nutrients and lower cost per kg body weight gain than those of group
T1. Among the two gritham residue supplemented groups better results could be
achieved at 10 per cent level of incorporation as indicated by the lower and better
FCE, significantly higher total weight gain and average daily gain, significantly
higher EE, NDF and ADF plus lower cost per kg gain in kids of group T2, fed on
10 per cent panchagavya gritham residue when compared to those of T3, fed on 20
per cent.
Therefore, it can be concluded that incorporation of ayurvedic pharmaceutic
residues such as panchagavya gritham, in kid starters in place of costly conventional
feed ingredients will help in the preparation of cost effective kid starters, without
compromising on nutritional quality. This will in turn help in reducing the feed cost,
thereby ensuring better economic returns to the farmers
