Abstract
Two-hundred ten head of predominantly British and/or British x Continental cross heifers were assigned to six implant/reimplant treatment groups (five pens/treatment). In addition, melengestrol acetate (MGA) was provided to four treatment groups from day 28 until 48 hours prior to slaughter. Heifers not fed MGA had the greatest number of immature ovaries, although they were also the most efficient in feed conversion (lower feed to gain ratio). Heifers fed MGA and implanted with Finaplix were the least efficient in feed conversion
