Result: Low milk yield is a common problem among cattle in field condition and pineapple waste is found dump during peak harvest period which may be utilized as forage to animals for increase milk yield. KVK Kishanganj conducted On Farm Trail during 2015-16 to substitution of green fodder with pineapple leaves in feeding schedule of dairy animals. The feeding experiment for the period of 15 days duration was conducted on 24 lactating cows at village and divided into four groups having 6 cows each. The experimental animals were housed in ideal sheds with proper ventilation. Health Care practices like vaccination and deworming was carried out as per schedule before starting of experiment. 

The result obtained indicates that the traditional feeding schedule along with 25% substitution by pineapple leaves recorded higher milk production (11.79 lit/day) and feed intake ( 8.6 kg/day)  of T1 in comparison to 50 %, 75 % level  and farmers practices. This treatment showed higher net return and B:C ratio and  edge over farmers practices. The substitution of green fodder with pineapple leaves up to level of 25% in feeding schedule of dairy animals provides beneficial effect on increasing feed intake and milk yield.
