    The experiment was conducted to iovestigate the effects of floor space per head on the growth rate and carcass characteristics of feeder male lambs during the last 2 months period. Twenty Suffolk male lambs at 8 months of age were used for the experiment. Five were allotted to each of four groups;
    group (1) with 2.4m2 of floor space par head, group (2) with 1.8m2, group (3) with 1.2m2 and group (4) with 0.6m2.
    There was no significant difference between the groups in daily live-weight gain, the feed conversion ratio and the dressing Percentage. In order to keep healthly condition, however, it would be required to improve the management and equipment for sheeps with 0.6m2 of floor space.

    1. To study the effects of water, salt and sunshade at pastures on body weight changes and carcass characteristics of lambs, Finnish Landrace (F) ×Suffolk (S) male lambs were grazed on a pasture with water, salt and sunshade (pasture I) and another pasture without those (pasture II). 5 lambs were investigated for 95 days, respectively. Corridale (C) male lambs also were grazed on both pastures for first 28 days.
    2. F×S lambs on pasture I drank water of 1.4kg/ head daily, licked salt of 1, 2g/ head daily. They utilized sunshade very frequently on sunny days in summer and their utilization was remarkably increase than that of C lambs.
    3. The body weight changes of lambs on pasture II were influenced seriously by weather conditions.F×S lambs on pasture I were heavier than F×S lambs, on pasture II by 20g of daily gain or 1.6kg of final body weight. There was, however, on difference in carcass characteristics between two pastures, and both were suitable for fat-lamb production.
