| 总结: | Four experiments were conducted to investigate the
productive performance of Sahiwal-Friesian cows under different
feeding managements. Rotational grazing at stocking rate 6.25
milking cows ( AU ) / ha on Setaria splendida and stall- fed cut
Panicum maximum ( Guinea grass ) both with high cost concentrate
containing 5.0 % fish meal supplementations ( Experiment I) were
done following split - plot in time design , followed by
( Experiment 11 ) comparing ( t-test ) the performance of cows
grazed on splendida ( rotationally ) at low ( 4.0 AU/ha ) and high
SR (8.0 AU / ha ) with low cost concentrate (LCF) supplementation
for HSR group . A split - plot in time design was also used to
determine the effect of type of concentrates formulated based
on cost with cut Guinea grass on the performance of the cows
( Experiment III), and to evaluate the effect of machine milking with the presence and the absence of calves (Experiment
IV). |
