Abstract
The study was carried out to know the growth potentiality of Malnad Gidda
(MG) calves by providing different levels of nutrients by dividing nine calves (Avg.
b.wt. 22 to 25 kg and age: 90 to 200 days) into three groups of three calves each in
switch over design. The calves in T1, T2 and T3 groups were fed to support 100, 150
and 200 g gain per day respectively and total DMI (g/d) and average daily gain (g/d)
in the corresponding groups were 750 and 152.30; 789 and 165.90; 872 and 181.30
respectively. The DMI on percent of body weight in the corresponding groups were
0.89, 0.95 and 1.2 respectively. There was no significant difference in nutrient and
mineral intake between the groups. The digestibility of all the nutrients increased
numerically but the difference was not significant between the groups. The DCP of
the diet in T1, T2 and T3 was 7.95, 8.70 and 9.03 % and TDN of the diet in all the
groups was around 55%. The total cost incurred in T1, T2 and T3 was Rs; 9.08, 9.76
and 12.20 per day respectively and cost of per kg body weight gain in corresponding
groups was Rs; 59.35, 58.10 and 67.40. It was concluded that the MG calves had the
potentiality of gaining only less than 180g gain per day with an average DMI of 2.0%
of body weight.
Key words: Malnad Gidda calves, weight gain, nutrient intake, digestibility,
