Under scarcity of livestock feeds and fodder, an investigation on alternate, conventional and nonconventional
feed resources is essential. The present study was planned on crossbred heifers (HF×Kankrej)
with average body weight of 116.1±4.74 kg for twelve fortnights to study the effect of feeding rice
DDGS and a combination of straw (wheat + groundnut) on their hemato-biochemical and mineral profile.
Blood samples for hemato-biochemical and mineral profile analysis were collected from heifers at
the start of the experiment and thereafter at every fortnightly interval from the jugular vein in the sterilized
blood collecting tubes (with and without anticoagulant). Auto-hematology-analyzer Mindray (BC-
2800Vet) and Mindray BS-120 chemistry analyzer were used for hematology and serum biochemistry
analysis, respectively. The RBC counts, Hb, PCV%, MCHC, Platelet count, MPV, WBCs and Granulocytes
changed significantly (P<0.05) on feeding DDGS though their values were within normal physiological
range. On feeding mixture of straw, platelets count and granulocytes changed significantly
(P<0.05) but their values were also within normal physiological range. On inclusion of Rice DDGS,
serum total protein, urea and phosphorus and on feeding mixture of straw serum glucose, albumin, urea
and phosphorus values differ significantly (P<0.05). The serum total protein, glucose, albumin and urea
values were within normal physiological interval on feeding DDGS or mixture of straw except phosphorus
values (8.77-9.33 mg/dL) which was higher than normal range in all treatment groups irrespective of
treatment. The results showed that rice DDGS in concentrate up to 40% and feeding a mixture of groundnut
straw and cereal straw (1:1) did not adversely affect the hematology, blood biochemical parameters and
mineral profile, all parameters were within normal physiological values except serum phosphorus which
was higher than the normal physiological values.
