“…Histological sections were prepared from all major organs. Five cardiac sections, one from each of the right and left ventricles and atria, and the interventricular septum, were prepared from each pig as described previously (Friend et al 1975a). Cardiac samples were also taken for lipid extraction and GLC analysis of component fatty acids as described by Kramer et al (1913) .…”

“…Arlo (15 %) plus Echo (85 %), seed varieties high in 22:1 and 20:1. The basal diet contained corn, wheat, soybean meal, corn starch, cellulose, calcium phosphate, limestone, salt, trace minerals and vitamins; further details have been described elsewhere (7,13). A total of 36 boars were used for the experiment; 5 were allotted at random to each of 3 pens per diet and 3 acting as initial controls for each dietary group were killed on day zero.…”

“…Cardiac fat and 22:1 accumulation in the heart is high, reaching a maximum within the first week and thereafter decreasing gradually but not disappearing entirely (9)(10)(11)(12). Boars fed for 20 days a diet containing 10% by weight Span RSO (B. campestris) with 4.3% erucic acid, accumulated about 0.8 % of this acid by the eighth day and its concentration was relatively unchanged by the last day of feeding (7).…”

Fully refined rapeseed oil, Brassica campestris var. Arlo plus Echo, and corn oil were fed at 20 % by weight of a basal diet to young Yorkshire boars. A serial slaughter technique was employed whereby 3 boars from each dietary treatment were killed at 0, 1, 2, 3, 4 and 8 weeks of the experiment. The fatty acid profiles of heart, liver, adrenals and testes lipids were investigated. The typical fatty acids of rapeseed oil, erucic and eicosenoic acids, were incorporated at different levels into the tissue lipids examined. After feeding the rapeseed oil diet for 1 week, the relative concentration of these fatty acids increased in the adrenals, while remaining similar in the heart, liver and testes. The relative concentration of eicosenoic acid was greater than that of erucic acid in all organs examined, except for the heart which contained equal amounts of these acids. Tissue levels of these acids in boars were compared to those found in rats fed the same rapeseed oil in previous studies.
