Abstract
Twelve Gir heifers were divided into three groups of four
animals each and alloted to three dietary treatments as follows:
All the animals were offered Pasture grass hay ad lib + 5 kg
green Jowar. In treatment-1 (Ti), Gir heifers were fed
Concentrate to meet the DC? requirement while those in
treatment-2 (T2) were fed as per the Ti group but 10%
concentrate was replaced by Groundnut haulms on
isonitrogenous basis and animals of treatment-3 (T3), were fed
as per the Ti group but 20% concentrate was replaced by
Groundnut haulms on isonitrogenous basis.
The average total live weight gain (kg) and average daily
gain (g) in live weight were 28.8, 29.75, 30.2 kg and 479 10
484.60 and 503.19 g, respectively for T,, Tj, and T3 group. Non
significant differences were observed for average total gain (kg)
and average daily gain (g) in live body weight.
The daily DM intake kg per day and kg per 100 kg body
weight were 3.70, 3.77 & 3.88; and 2.70, 2.80 & 2.91
respectively in Ti, T2. and T3 group. Non significant differences
(P>0.05) were observed for daily DM intake kg per day and kg per
100 kg body weight basis between the groups. The CP(g), DCP (g)
and TDN (kg) intakes were 450.45, 460.85 8s 475.23; 307.58
315.16 8s 324.11 and 2.35, 2.40 8s 2.45 respectively in Ti Ta
and T3 group in which treatment differences were nonsignificant.
The digestibility of DM, OM, CP, EE, OF and NFE was
47.03%, 46.43%, 65.65%, 51.97%, 50.78% and 46.43%,
respectively in Ti.The corresponding values in Ta were 44.66%.
47.54%, 66.84%, 52.74%, 52.54% and 47.57% while in T3 they
were 47.74%, 48.87%, 67.82%, 52.00%, 53.87% and 48.87%
Overall the treatment differences were non significant (P>0 05)
The differences in digestibility coefficient for DM, CM, EE
CP, CP and NFE were non significant (P>0.05) among the
different treatment groups.
Feed conversion ratio (DMI per kg live body weight gain)
was non significantly different among the different groups. The
cost of feeding per kg live weight gain was lowest in T3 group (Rs
47.17) and highest in Ti (Rs. 57.28).
Overall findings of the present investigation indicate that
partial replacement of concentrate mixture with groundnut
haulms does not exhibit any adverse effect on dry matter intake,
growth, biometry changes and digestibility of nutrient in the
growing heifers. Additionally, it also reduces the cost of feeding
to the extent at level of 8.91o/„. Therefore, it is beneficial to
replace concentrate mixture with groundnut haulms at 20% level
in the ration of Gir heifers.
