“…[10] showed that the ratio of dietary polyunsaturated fatty acids/SFAs was significantly related to the saturated and polyunsaturated content of subcutaneous adipose tissue. van Niel and Beynen also reported a strong correlation in C18:2 and C18:3 levels between diet and subcutaneous adipose tissue in cats [30], as in other species [16, 18, 20, 29]. In our previous trial [14], the fatty acid profile in subcutaneous adipose tissue in experimental and control cats also reflected the dietary fatty acid profile.…”

To evaluate the effect of overfeeding on fatty acid distribution and metabolism, especially stearoyl-CoA desaturase-1 (SCD-1) indices, 8 cats in the experimental and control groups (4 per group) were evaluated in this study. The experiments involved feeding the experimental group cats twice their daily energy requirement with a commercial diet for 4 weeks. The control group was fed the estimated daily energy requirement with the same diet. Body weight, feline body mass index, body condition score, several zoometry measurements, and plasma metabolites/hepatic injury markers were measured in all the cats before and after the experiment. In addition, the fatty acid profiles in the liver and subcutaneous adipose tissue were measured after the experiment. After 4 weeks of overfeeding, the experimental group demonstrated significant increases in hepatic C18:1, plasma triglyceride, and nonesterified fatty acid (NEFA) concentrations and in alanine aminotransferase activity. Furthermore, hepatic SCD-1 indices were positively correlated with body weight, feline body mass index, body condition score, and plasma NEFA concentration, although subcutaneous adipose tissue did not demonstrate any increase in SCD-1 indices in this study. The increase in hepatic SCD-1 indices might be enhanced by the inflow of plasma NEFA into the liver, and NEFA toxicity might stimulate C18:1 synthesis by SCD-1.

“…Van Niel & Beynen (69) found strong correlations between the intake of LA (R 0•99), ALA (R 0•99), EPA (R 0•94) and DHA (R 0•91) and their deposition in cutaneous adipose tissue in cats. Dietary concentrations of n-3 fatty acids were shown to determine their deposition in the female reproductive system (follicular fluid, granulosa cells, cumulus-oocyte complex and ovarian tissues) in cattle, ewes, mice and rats, but the biological significance of these findings remains controversial (70) .…”

DHA from microalgae Schizochytrium spp. (Thraustochytriaceae) modifies the inflammatory response and gonadal lipid profile in domestic cats

This study aimed to evaluate the inflammatory response, oxidative status, and fatty acid deposition in reproductive tissues of cats supplemented with the dried microalgae Schizochytrium spp. (Thraustochytriaceae) as docosahexaenoic acid (DHA) source. Thirty-seven cats (males, n= 21; females, n= 16; 11.5±0.5 months of age) were divided by sex into five groups. Treatment diets contained algae biomass at 4.0, 8.0, 12.0, or 16.0 g/kg replacing poultry fat (omega-6 source). Cats were fed the respective diet for 62 d and neutered on day 58. Blood samples were collected at the beginning of the experiment (day 1), before neutering (day 58), and four days after surgery (day 62) for analysis of inflammation and oxidative markers. Acute-phase protein levels were altered (P < 0•01) in the postoperative period, without any treatment effect (P > 0•05). Prostaglandin E2 (PGE2) concentrations after surgery was reduced linearly (R2 = 0.8706; P = 0•002) with microalgal inclusion. Blood platelet count was reduced (P = 0•001) after the surgery regardless treatment but, it was higher in the DHA group compared to Control (P < 0•001). The DHA deposition (testicles, R2 = 0.846; ovaries, R2 = 0.869), and the omega-6/omega-3 ratio (testicles, R2 = 0.859; ovaries, R2 = 0.955) in gonads had a pattern which fitted a quadratic model. DHA from Schizochytrium spp. modifies PGE2 response after the surgery in cats. The physiological roles of the DHA in the reproduction of cats were not investigated, but its gonadal deposition after supplementation was observed.

“…Adipose fatty acid signatures have been shown to correlate with dietary fatty acids of assorted prey species in various carnivores including mink (Mustela vison), grey seals (Halichoerus grypus), harp seals (Phoca groenlandica), harbor seals (Phoca vitulina) [Iverson et al, 2004], and domestic cat (Felis catus) [Van Niel and Beynen, 1997]. There is positive correlation between the percentages of polyunsaturated fatty acids in the diet and those in subcutaneous fat of humans, pigs, rats, rabbits, chickens, lambs, nonruminant calves, and cats [Van Niel and Beynen, 1997], although there does seem to be some modification of dietary fats before deposition in polar bears [Grahl-Neilsen et al, 2003]. The fatty acid composition of maternal diet of female mink (Mustela vison) affects the fatty acid composition in milk and kit tissue [Hansen et al, 2004].…”

This study compared the fatty acid composition of polar bear (Ursus maritimus) adipose tissue (n 5 2) to the fatty acid (FA) composition in published literature for maternal milk (n 5 3 samples) and a primary milk formula (liquid Esbilac, Pet Ag Inc., Hampshire, IL) commonly used in hand rearing, to look at possible dietary influences on ultimate body fat constituency. All tissue and commercial milk fatty acids were analyzed on a percent relative (% of fat) basis for consistency in reporting results and to make easier comparisons between samples with varying fat contents. Thirty-eight individual fatty acid profiles were measured and the results tabulated into saturated, monounsaturated and polyunsaturated fats. The tissue adipose results for the two cubs had similar patterns throughout the assay. Saturated FA totals were 30% of the total fat, monounsaturated FA represented 50% of the total fat, and polyunsaturated FA was 15%. Similar fatty acid proportions were reported when comparing adipose to published data for maternal milk of polar bears. The most striking differences were between the commercial milk replacer (liquid Esbilac) and the tissue samples and maternal milk values. Esbilac FA summaries for saturated FAs were 24%, monounsaturated were 26%, and polyunsaturated comprised 50% of the total fat. Polyunsaturated fat in Esbilac is substantially higher than the tissue and milk scores. Although lipid sources from whole cream or half-and-half are used to increase the fat concentration of milk replacers for the hand-reared polar bear cub, alternative ingredients such as fish oil may prove more suitable for this
