“…It would appear, however, from the total heart lipid analysis of pigs (Kramer et al 1975b), monkeys (this study; Ackman and I-new 1911) and possibly rats (Hung et al 1911) that C-22 monoenes are normal fatty acid constituents present in trace amounts (Williams et al . 1912) and thus may affect their fragility (Dow-Walsh et al 1975 (Kramer et a\.…”

Male and female cynomolgus monkeys (Macaca fascicularis), equally divided as to sex, were fed, up to 24 wk, diets which contained 20% by weight of either soybean oil or Brassica napus cv. Tower rapeseed oil which contained 0.2% erucic acid. Long-chain monoenes appeared to accumulate in the cardiac lipids of both sexes fed Tower rapeseed oil. Histochemical studies suggested no myocardial damage associated with the feeding of either diet. Histopathological examination of the hearts of monkeys fed the two diets showed that only two male monkeys fed soybean oil for 24 wk had myocardial lesions, and these were multiple small foci of mononuclear cells. The results indicate that Tower rapeseed oil is indistinguishable from soybean oil in its nutritional and pathological properties.

“…1913;Rocquelin et al 1973). The accumulation of erucic acid in lipids of pigs is much lower than that observed in the rat fed the same rapeseed oil at the same level in the diet (Kramer et al 1975). Microscopic examination has shown mild lipidosis in pig hearts which declined after 45 days of feeding (Vodovar et al t913).…”

“…A species comparison of the incorporation of 20:1 and 22:1 into cardiac lipids of chickens fed Regular RSO with that in rats (Kramer et al, 1979), pigs (Kramer et al, 1975;Von U. Petersen et al, 1979; data for week 17 only), and monkeys (Beare-Rogers and Nera, 1972) fed the same or similar RSO can also be made. Such a comparison is illustrated in Figure 1.…”

A total of 384 male Single Comb White Leghorn chicks of the Hyline strain were randomized in 24 Petersime battery units of 16 birds per unit. Four replicate pens were fed either a basal (control) diet containing no added oil or a diet supplemented with 20% by weight of either soybean oil or rapeseed oil (RSO) from cultivars Tower, Candle, Regular, or R-500. Levels of crucic acid (22:1) in the RSO's ranged from .1 to 51.6%. Four birds from each unit were killed at 4, 8, 12, and 16 weeks for cardiac lipid analysis and pathology. Feeding RSO had no consistent effect on body weights, heart weights, or the heart-to-body weight ratio. Only the diet containing R-500 (51.6% 22:1) consistently increased cardiac lipid levels as measured gravimetrically. Maximum deposition of the long-chain monoenes (22:1) and eicosenoic acids (20:1) occurred in the cardiac lipids by 8 weeks, and the levels remained high throughout the 16-week trial. The relative concentration of these long-chain monoenes in the cardiac lipids was positively correlated to the dietary levels of these acids. The incidence of lesions found in heart, liver, and skeletal muscle was significantly higher in chickens fed RSO's high in 22:1 than in chickens fed control or soybean oil, and the incidence significantly correlated to the level of 22:1 in the diet. The incidence of heart and muscle lesions and sinusoidal distention in chickens fed RSO's low in 22:1 was not significantly different from that of chickens fed the control diet or soybean oil, but the incidence of hepatic necrosis was significantly higher for chickens fed RSO's low in 22:1 compared to those fed the control diet or soybean oil.
