Some of the recommended calf management related techniques were evaluated under field conditions of Toba Tek Singh with the support of Endowment Fund Secretariat University of Agriculture Faisalabad. The objective was technology transfer through trials as adoption trend of techniques boost through this way. For this purpose, three trials were conducted and in each trial recommended technique were compared with the traditional practice that was on going. In first trial, ten calves were fed colostrum within an hour post milking and other ten calves after dam placenta expulsion. Data related to calf health, dam health, time of placenta expulsion was recorded. Study results indicated that up to 90% calves remained healthy due to timely colostrum feeding but 50% calves in second group showed the symptoms of white scour and bloat frequently up to two months age and 30% calves died. Time of placenta expulsion decreased to a large extent due to in time colostrum feeding as 90% dams expel placenta with in 2 hour post calving. However, time of placenta expulsion increase due to delayed colostrum feeding as 50% dams expel placenta at 12 hours, 30% at 3 hours post calving and 20% showed the problem of retained placenta. Delayed placenta expulsions lead to mastitis (30%), metritis (20%) and prolaps (20%) during a study period of 2 months. In second trial, 16 calves were selected and divided into two groups. One group was fed the milk through artificial mean (bottle) an
d other group as farmer's routine (direct suckling). Data regarding body condition of calf and dam udder / teat status was recorded up to 2 months. Direct suckling was found injurious both for calf and dam. About 70% calves remained underfed and others overfed. Fifty % calves damaged the teats of dams by teeth and 30% dams showed the symptoms of mastitis. However, feeding the calves through artificial means get the exact quantity of milk (10% of body weight) and remained healthy (87.5%) and in good condition. In third trial, effect of naval cord care was determined on calves' health. For this purpose, the naval cord of eight calves was properly cut and sprayed and other group kept as such (no naval cord cut and care as farmer's routine). These calves remained under observation up to 2 months age. Trial results indicated that naval cord care kept all the calves safe from omphalitis. However, in untreated group 50% calves showed the symptoms of omphalitis and 25 % died due to septicemia.
