In: Egyptian Journal of Nutrition and Feeds 2003.v6 (2)Summary: Thirty-four newly born calves were assigned to two similar groups, 17 in each (10 males and 7 females). The first group was given non-supplemented diet and whole milk (control) until weaning at 90 kg live body weight (LBW); The second one received whole milk supplemented with 2g Acid-Pak 4 way (AP)/liter and 2kg Lacto-Sacc (LS) I ton calf starter until 70 kg LBW (early weaning), thereafter they were fed on starter supplemented with LS up to 90 kg LBW. Results showed that total weight gain (1WG) and average daily gain (ADG) insignificantly increased in treated calves as compared to control during the growth interval from birth to 70 kg LBW (the 1st interval), and from birth up to 90 kg LBW (overall interval) while ADG was signifIcantly higher from 70 to 90 kg LBW (the 2nd interval).
