“…The latter two acids are relatively common in some plant oils and it is important to make sure they are absent from the diet. Their presence can be reflected by the reduced A9-desaturase activity with saturated fatty acids in the hen's liver, which explains why such diets are not successful in breeding healthy chicks (Donaldson 1967;Pearson et al 1972;Vogtmann et al 1974). Neither of these undesirable fatty acids were detected in the kakapo diets so they cannot be involved in reducing the survival of the kakapo in their natural habitat.…”

“…However, provided substantial food is present even with low levels oflipid extract from the leaves and stems rich in 18:2 or 18:3, if an adequate volume of foliage is consumed, satisfactory quantities of essential fatty acids will be available. The direct effect that dietary fatty acids have on the fatty acid content of the egg yolk was demonstrated when domestic hens were fed diets including (i) fish meal (Edwards & Marion 1963;Navorro et al 1972), (ii) rapeseed oil (Vogtmann et al 1974;Vogtmann & Clandinin 1975), or (iii) cottonseed oil (phelpsetal.1965;Abou-Ashour&Edwards 1970). The egg yolk fatty acids of these hens were enriched with either (i) W3-poly-unsaturated, (ii) erucic (22:1 W9), or (iii) cyclo-propene fatty acids.…”

“…We attempted to determine whether adequate levels of essential fatty acids were available in the diet and Downloaded by [Universitat Politècnica de València] at 01:19 20 November 2014 eggs for normal chick development, and to detect the presence of undesirable dietary fatty acids in the kakapo's diet, such as erucic or cyclopropene fatty acids, that could affect detrimentally the health of chicks (Donaldson 1967;Pearson et al 1972;Vogtmann et al 1974). This information on lipid composition and quantity ofkakapo food and eggs from Stewart Island may be useful in future efforts to conserve the species through supplementary feeding.…”

The lipid compositions from yolks of a clutch of four infertile kakapo eggs were determined and compared with those of other species. The principal components were triacylglycerols (64%) and phospholipids (23%), made up mainly of phosphatidyl choline (16%) and phosphatidyl ethanolamine (3%). Studies of the individual fatty acid compositions of these lipids were undertaken and the stereospecific distribution of the saturated and polyunsaturated essential fatty acids in the major phospholipids reported. These results, together with those for the fatty acid compositions of lipids extracted from the dietary intake of plant material available for the kakapo, indicated that there is adequate linoleic acid in the birds' diet. Also, no toxic fatty acids occurred.

“…Similarly, egg weight was not significantly different between 3% and 5% canola oil addition groups (Rowghani et al, 2007 ). However, Vogtmann et al ( 1974 ) showed that feeding Leghorn hens with 15% high (26.2%) erucic acid rapeseed oil decreased feed intake and egg production in comparison with 15% low (4.1%) erucic acid soybean oil. In a similar study, the effects of different levels of canola oil (0, 2.0, 4.0 and 6.0%) on the performance of laying hens were investigated and it observed that the use of increasing levels of canola oil decreased egg production, egg weight, and daily feed intake but did not affect the feed conversion (Gul et al, 2012 ).…”

Effects of supplementation with different rapeseed oil sources and levels on production performance, egg quality, and serum parameters in laying hens

This study was to determine the effects of rapeseed oil on production performance, egg quality, and serum parameters in laying hens. A total of 1,080 hens (33-wk-old) were randomly divided into a 1 plus 4 × 2 factorial design including four different rapeseed oil sources [high erucic acid of Mianyang city (MH); high erucic acid of Deyang city (DH); low erucic acid of Mianyang (ML); low erucic acid of Deyang (DL)] at two levels (2% and 4%) for 12 wk. The egg production and egg weight were decreased (P < 0.05) during 9 to 12 wk and 1 to 12 wk, while the average daily feed intake (ADFI) and feed conversion ratio were decreased (P < 0.01) in all phases compared to the control group. Adding ML as oil source had higher (P < 0.05) egg weight compared to DH in all periods in spite of levels. Meanwhile, layers fed 4% rapeseed oil decreased (P < 0.01) egg production compared with 2% in all phases except 1 to 4 wk. Regardless of rapeseed oil sources, hens fed 4% oil decreased (P < 0.05) egg weight in contrast to 2% during the whole experiment except 5 to 8 wk. The ADFI was lower (P < 0.01) in 4% oil inclusion groups compared with 2% during overall phase. Rapeseed oil decreased the yolk color (P < 0.01) and yolk ratio (P = 0.02) and increased (P < 0.01) the albumen height and Haugh unit at 12 wk. Dietary rapeseed oil supplementation resulted in a decreased total triglyceride (TG; P < 0.01) and increased high-density lipoprotein cholesterol (P = 0.02). Regardless of rapeseed oil levels, layers fed MH had higher TG (P < 0.01), TC (P < 0.05), low-density lipoprotein cholesterol (P < 0.05), alanine transaminase (P < 0.01) than those fed other sources. Taken together, the addition of rapeseed oil decreased laying performance, reduced TC and TG in the serum, and increased Haugh unit, with low erucic acid or 2% group showed more pronounced results among all treatments.

“…Per cent egg production was influenced significantly by the kind of oil in the diet. Significantly lower egg production was noted when hens were fed a diet containing 15% HEAR oil compared to hens receiving 15% soybean oil; the production being intermediate with LEAR oil (Vogtmann et al., ).…”

Erucic acid is the trivial name of the fatty acid cis-13-docosenoic acid and occurs at high concentrations mainly in the seeds of species of the Brassicaceae (e.g. rape seed or mustard seed). The European Commission requested EFSA to deliver a scientific opinion on the risks for animal and human health related to the presence of erucic acid in feed and food. For most humans, the main contributor to dietary exposure to erucic acid was the food group 'Fine bakery wares'. In 'Infants', 'Food for infants and small children' was the main contributor to exposure. The heart is the principal target organ for toxic effects after exposure. Myocardial lipidosis was identified as the critical effect for chronic exposure to erucic acid. This effect is reversible and transient during prolonged exposure. A tolerable daily intake (TDI) of 7 mg/kg body weight (bw) per day for erucic acid was established, based on a no observed adverse effect level of 0.7 g/kg bw per day for lipidosis in young rats and newborn piglets. Mean chronic exposure of the different groups of the population did not exceed the TDI. The two highest 95th percentile dietary exposure levels were observed for infants (ranging from 1.7 to 7.4 mg/kg bw per day, minimum lower bound (LB) -maximum upper bound (UB)) and other children (ranging from 2.1 to 9.5 mg/kg bw per day, minimum LB -maximum UB), the last max UB estimate being above the TDI. This may indicate a risk for young individuals with high erucic acid exposure. In pigs, levels of erucic acid are unlikely to represent a health concern. However, for poultry, the small margin between the lowest observed adverse effect level (LOAEL) and the estimated exposure may indicate a health risk where maximum inclusion rates are applied. Due to the absence of adequate data, the risk for ruminants, horses, fish and rabbits could not be assessed.
