Abstract
Astudy was conducted to assess the growth and feed cost
in lambs fed rations containing different roughage to
concentrate ratios during January to May 2019.Eighteen male
Mecheri lambs (3 months old and 11.80± 0.16kg body weight)
were randomly distributed into three groups of six each.
Sorghum stover was the roughage and roughage: concentrate
fed ad libitum to lambs in 50:50, 60:40 and 70:30 ratios for a
period of 120 days. The body weight gain, average daily gain,
growth rate and feed conversion efficiency were significantly
(p<0.001) higher in lambs fed 50% concentrate followed by 40
and 30% respectively. Higher proportion of concentrate in the
ration significantly (p<0.05) influenced the serum cholesterol
and inorganic phosphorus concentration. Feed cost/kg live
body weight was lower in lambs fed 50% concentrate (Rs.
35.58/kg gain) followed by 40 (Rs. 42.43/kg gain) and 30%
concentrate (Rs. 56.98/kg gain). Feeding of roughage and
concentrate in 50:50 ratio was found ideal for better growth
and feed efficiency in lambs.
