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.
