Green Berseem as Substitute for Economic Feeding of Dairy Cattle
It was not possible to find out the difference, if
any, between the breeds due to the inadequate
number of animals of each breed in a group. The
experiment was repeated in 1940 to determine the
effect due to breed and to confirm the above find-
ings. Nine Hissar cows and nine Murrah buffaloes
were distributed into three comparable groups,
after a basal feeding period of two weeks. The
distribution of animals into different groups is
shown in Table XIII.

The experiment was split into three periods.
The treatments, (I) full concentrates, (II) half the
protein of the full concentrate ration replaced by
green berseem and (III) three-fourth of the protein
replaced by green berseem were tried on all the
groups in cyclic order. The plan below illustrates
the lay out.

By this arrangement all the 18 animals received
all the three treatments during the test, thus
eliminating the effect due to individuality and the
stage of lactation. As the test had to be con-
cluded within the berseem season, each period of
feeding could be continued only for five weeks.
The milk yield due to the different treatments are
given in Table XIV.
The results of the statistical analyses of the milk
yield of the different groups corroborate the find-
ings of the previous experiment. The adjusted
milk yield per day with the Hissar breed is 9.95,
9.32 and 9.33 and with the Murrah breed is 15.28,
16.04 and 15.05 for T 1 , T 2 and T 3 respectively,
with a standard error of 0.3541. Hence, the
difference in the milk yield due to the different
treatments is not significant to a level of 5 per cent
either with Hissar or Murrah, but the difference
due to T 2 and T 3 with the Murrah breed is on the
verge of significance.
Effect of green berseem on the composition of milk
During the course of the experiment milk
samples from all the animals were analysed periodi-
cally for three consecutive days both morning and
evening. Analyses of fat were made after each
sampling and aliquotes were preserved for complete
analysis. There was no appreciable difference in
the composition of milk due to the different feeds.
