A Comparison between the effects of ryegrass and white clover on the iodine values and melting points of some depot fats of sheep

Abstract
1. The mean iodine values and melting points of the fats from 16-month-old Romney wethers grazed on different pasture species including: perennial ryegrass or short-rotation ryegrass alone or admixed with white clover were as follows perinephric, i.v. 41.3-46.1, M.P. 47.7-49.4°C; omental, i.v. 43.2-47.4, M.P. 46.6-47.4°C; subcutaneous, i.v. 46.4-50.4, M.P. 44.2-46.0°C and 1. dorsi muscle, i.v. 57.5-60.3, M.P. 39.7-41.5°C. The iodine values were several units higher than those obtained previously (Shorland etal. 1962) for corresponding fats from mature Romney ewes.
