Abstract
A study was conducted to assess the effect of dietary incorporation of
ayurvedic pharmaceutic gritham residues on growth performance of Malabari kids.
Four ayurvedic pharmaceutic gritham residues, viz., indukanta gritham, tiktaka
gritham, brahmi gritham and saraswata gritham were tested in vitro by in vitro gas
production technique (IVGPT) to estimate metabolisable energy (ME), digestible
organic matter (DOM) and in vitro digestible nitrogen (IVDN) and were ranked on
the basis of a six point scoring system. Brahmi gritham residue which obtained the
highest aggregate score was selected as the best ayurvedic pharmaceutic gritham
residue which was used for further in vivo study.
Three isonitrogenous and isocaloric rations, T1, T2 and T3 without and with
10 and 20 per cent brahmi gritham residues, respectively, were formulated as per
ICAR feeding standards (ICAR 2013). Fifteen Malabari kids were selected, 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.
The average daily gain and total average weight gain of kids were 56.44,
64.66, 54.88 g per day and 5.08, 5.82, 4.94 kg, respectively in groups T1, T2 and
T3 and were similar (P>0.05). The average daily dry matter intake was 0.52, 0.56
and 0.57 kg per day, for kids in groups, T1, T2 and T3, respectively and the values
were similar (P>0.05). The average values of FCE of experimental kids fed on
rations T1, T2 and T3, were 4.62, 4.48 and 5.13, respectively, and statistical
analysis of the data showed that the FCE was similar (P>0.05). There was no
significant (P>0.05) difference in digestibility coefficient of nutrients except ether
extract which was significantly higher (P<0.05) in T3 than T1, with T2 being
similar (P>0.05) to both T1and T3 and NFE which was significantly higher
(P<0.05) in T1 and T2 than T3, with T1 and T2 being similar (P>0.05). Haematobiochemical parameters were similar among the three groups and the values were
within the normal range of kids. The cost per kg body weight gain was Rs. 171.22,
141.88 and 149.91 for kids in groups, T1, T2 and T3, respectively.
The results obtained from the present study indicate that kids in groups T2
and T3 showed similar growth as that of T1 (control), T2 being slightly better than
T3, as evinced by the lower and better FCE and lower cost per kg body weight gain
in T2 than T3.
An overall critical evaluation of the results of the present study indicate that
brahmi gritham residue can be safely incorporated in kid starter up to 20 per cent
without affecting the growth performance of kids and better results can be achieved
at 10 per cent level of incorporation. This will help in the preparation of a cost
effective kid starter instead of costly conventional ingredients, thereby reducing the
feed cost and ensuring better returns to the farmers
