280 Berseem hay for Dairy Cattle
The animals were not allowed to leave any
residue from concentrate, berseem or jowar.
The amount of food consumption and liveweight
increase of the individual animal was recorded
daily. The experiment lasted for a period of
17 weeks. The distribution of the animals into
groups and their average liveweight during the
different weeks of the tests are given in Table I.

The average age, liveweight and increase in live-
weight of each breed under different treatments
during the basal period are nearly the same. But
the variation in the total increase due to the treat-
ments is quite significant. From the analysis of
co-variance and the adjusted analysis it is observed
that the effect due to treatments is significant to
a level of one per cent. The final adjusted live-
weights are 579, 548 and 528 lb. for Hissar and
587, 554 and 525 lb. for Murrah breed for group I,
group II and group III, respectively with a stan-
dard error of 5.496. The order of significance
is—group I> group II> group III for both the
breeds. Though the order due to feed is the same,
the Murrah heifers seem to be more adversely
affected than Hissar heifers when concentrates are
replaced by berseem hay. Rate of growth for
each animal due to the three treatments was
also compared by the formation of regression
