“…In another study, 8.84 g/day EPA and 10.43 g/day DHA supplementation of mares 60 days prior to expected foaling day resulted in an increase in the n‐3 fatty acid profile of milk, mare and foal plasma (Kouba, Burns, & Webel, 2019). However, although maternal supplementation of algae‐based DHA (2 g/day) altered foal plasma DHA concentrations, there was no effect on mare colostrum or foal serum IgG, IgA and IgM (Adkin, Warren, Mortensen, & Kivipelto, 2013) and no significant effects were found with respect to passive immunity transfer in foals from either n‐3 or n‐6 fatty acid supplementation of the mare's ration (Gobesso et al., 2020).…”

“…Previous studies, as described above, have mostly focused on just the effects of fish oil supplementation in pregnant mares and their newborn foals (Adkin, Warren, & McCall, 2013; Adkin, Warren, Mortensen, et al., 2013; Duvaux‐Ponter et al., 2004; Gobesso et al., 2020; Hodge et al., 2017; Kouba et al., 2019) but have not evaluated any potential added advantage of concurrent additional vitamin E supplementation.…”

The effects of fish oil (40 ml/day) supplementation, with or without synthetic all‐rac‐alpha‐tocopherol‐acetate (2,500 IU/day), during the last 65 days before expected parturition were investigated in 15 adult mares (553 ± 24 kg BW) and their foals. Mares were assigned to one of three diets: control (n = 5), control plus fish oil and alpha‐tocopherol (n = 4; FO + AT) or control with just fish oil (n = 6; FO). Blood samples were obtained from the mares before a 15‐day dietary adaptation period (T1) and from mares and foals the first (T2) and fifth (T3) days post‐partum. Colostrum was collected at T2 and milk at T3. Routine haematological, biochemical and alpha‐tocopherol analyses were undertaken on all blood samples. Fatty acid concentrations were determined in the foal serum and alpha‐tocopherol concentrations measured in the milk and colostrum. Diet had no effect on haematology or biochemistry in the mares. Alpha‐tocopherol concentrations were significantly higher at T2 & T3 in the FO + AT mares. Foal WBCs were higher in FO (11.33 ± 2.59 × 109/l), comparing to FO + AT and control groups (9.18 ± 1.24 × 109/l and 7.26 ± 1.03 × 109/l, respectively), at T3 (p < .05). There was no significant effect of the fish oil supplementation on the foal's serum fatty acid profile. In the FO + AT group, both colostrum and milk alpha‐tocopherol concentrations (2.56 ± 0.36 and 1.36 ± 0.22 µg/ml, respectively) were higher compared than those of the FO group (1.33 ± 0.39 and 0.72 ± 0.31 µg/ml, respectively; p < .05). Additional 2,500 IU/day of synthetic alpha‐tocopherol in the last 65 days of pregnancy increased alpha‐tocopherol concentrations in colostrum and milk and the foal's serum. 40 ml/day fish oil, however, did not significantly increase serum eicosapentaenoic acid and docosahexaenoic acid concentrations in the foals.
