Abstract
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.
