Abstract
The main
objective of the present study was to compare the effects of feeding value of
silages from whole crop maize (WCM) and maize Stover (MS) on dry matter intake
(DMI), milk yield and its composition in lactating Sahiwal cows. Eight cows
nearly of the same age, weight and lactation stage were randomly divided into 2
equal groups. A and B, Two rations viz I and II were randomly allotted to these
groups. Both the rations were based on 60% test materials (WCM or MS silage)
added with 40% concentrates. Each ration was offered ad libitum twice
daily. The experiment lasted for 20 days, allowing 10 days of adaptation period.
The data were statistically analyzed using completely randomized design. Non
significant differences were observed between both the groups of cows fed WCM or
MS silage for DMI, milk yield and its components such as fat and solid-not-fat,
total solids, crude protein and casein contents, Based on the findings of this
study. it was concluded that the overall response of the experimental cows to
the silages from MS and WCM was similar. Therefore, it was suggested that on the
commercial scale. for feeding dairy animals during drought season, conversion of
the maize stover into silage should be encouraged rather than whole crop maize.
