Abstract
A study was conducted to assess the effect of dietary incorporation of raw
banana peel silage on growth performance, nutrient utilisation and techno economics of production, in weaned Malabari kids. Based on the preliminary
laboratory trial, it was found that the combination of raw banana peel with three
per cent jaggery, ensiled for 24 days gave good quality silage with yellowish
brown colour, fruity odour and pH of 3.90. The above method was used for
preparation of silage in bulk and was used for subsequent in vivo study, viz.,
feeding trial.
A feeding trial of 60 days duration was conducted in eighteen Malabari kids,
divided into three groups of six each, as uniformly as possible with regard to body
weight, age and sex and randomly allotted to three groups T1, T2 and T3 and fed
on the respective isonitrogenous and isocaloric rations, on DM basis, so as to meet
the requirements as per ICAR feeding standards (ICAR 2013); viz., T1 was fed
with concentrate mixture and green fodder, T2 with concentrate mixture, green
fodder and 100 g raw banana peel silage and T3 with concentrate mixture, green
fodder and 200 g raw banana peel silage. Data on body weight gain, dry matter
intake (DMI), feed conversion efficiency (FCE), digestibility coefficient of
nutrients and cost per kg gain were employed for the evaluation of the work.
The average daily gain and the total average weight gain of kids were 55.97,
59.32, 56.80 g per day and 3.36, 3.57, 3.41 kg, respectively in groups T1, T2 and
T3, with both ADG and total average weight gain of kids in T2 being significantly
higher (P0.05) to both T1 and
T2. The average daily DMI of kids in groups, T1, T2 and T3 were 0.56, 0.58 and
0.60 kg per day, respectively and were similar. The average values of FCE of kids
fed on rations T1, T2 and T3, were 5.26, 5.02 and 5.39, respectively, with the
values being similar (P>0.05).
The digestibility coefficient of DM, CP, NFE, NDF and ADF of T1 and T2
were significantly higher (P0.01). The digestibility coefficient of EE was similar (P>0.05) whereas that of
CF was highest (P<0.01) in T2 followed by T1 and T3 in descending order. The
cost per kg body weight gain was Rs. 238.33, 226.04 and 246.74 for kids in
groups, T1, T2 and T3, respectively.
An overall critical evaluation of the results of the present study showed
that kids fed on a diet containing raw banana peel silage at 100 g level on DM
basis (T2), ie., 10 per cent level, had similar DMI, FCE and digestibility
coefficients of nutrients as that of an unsupplemented control diet (T1). Both T2
and T1, were better than T3, the diet containing raw banana peel silage at 200 g
level on DM basis, ie., 20 per cent level, in all aspects. Among T1 and T2 which
were more or less comparable and statistically similar, T2 was better than T1 as it
elicited a better production performance by way of significantly higher ADG,
higher total weight gain, better FCE and lower cost per kg gain than T1.
Therefore, it can be concluded that raw banana peel silage can be safely
incorporated as an alternative livestock feed in the ration of kids upto 100 g on
DM basis (10 per cent), replacing green fodder, without affecting growth
performance, with economic benefits.
