A study was conducted to assess the effect of replacing chia with flaxseed as a source of α-linolenic acid in laying hen feed. Five diets, identified as T0 through T4, containing 0-0, 7-3, 9-5, 11.5-2.5 and 14-0% whole chia seed and whole flaxseed, respectively, were fed to 240 White Shaver laying hens, at 60 wk of age. No difference (P > 0.05) in egg production, egg weight, yolk weight and albumen weight were found among treatments. Total ω-3 acid percentage was higher (P < 0.05) in the yolks from the hens fed the α-linolenic acid-enriched diets, than in those fed the control diet. Of the three treatments that had any combination of chia and flaxseed comprising 14% of the diet, T2 yielded a lower (P < 0.05) ω-3 content in the yolk, than did T3 and T4. A taste panel found no difference (P > 0.05) in flavor or off-flavor among treatments; however, panel preferences were lower for eggs produced by hens fed the highest level of flaxseed (T2). This study showed no advantages to replacing chia with flaxseed to produce ω-3 enriched eggs. Greater availability of flaxseed, however, might make it more attractive in some markets.

Grass Silage

Ruminant products have been criticised for the possible adverse effects of their saturated fatty acids on human health. Conversely, the omega-3 polyunsaturated fatty acids, notably those in fish oils, have been identified as beneficial components of the human diet. Earlier studies have shown that a small, but useful, amount of forage α-linolenic acid (C18:3), an omega-3 fatty acid, appears in ruminant products (Wood and Enser, 1996). The objective of the current work was to evaluate the range of α-linolenic acid concentrations in laboratory grass silages in order to assess the opportunities to modify ensiling techniques to increase the natural delivery of omega-3 fatty acid from grass silage to milk or meat.

Chia Seed

Western diets are typically low in ω-3 fatty acids, and high in saturated and ω-6 fatty acids. There is a need to increase dietary ω-3 fatty acid content. Chia (Salvia hispanica L.) has the highest botanical source of alpha-linolenic acid (ALA) known, and recently has been receiving more attention because of this. Feeding ALA to animals has been shown to increase the ω-3 fatty acid content of the foods they produce, and hence offers consumers an easy way to increase their intake of ω3 fatty acids without altering their diet. Broilers were fed rapeseed, flaxseed, chia seed and chia meal to assess the ability of these feed ingredients to increase the ω-3 fatty acid content of the meat, and also to determine whether any negative effects on bird production would arise. Flaxseed produced significantly (P < 0.05) lower body weights, weight gains and poorer conversion ratios than did the other feeds. Except in the case of the chia meal with the dark meat, the chia seed significantly (P < 0.05) reduced the saturated fatty acid (SFA) content of the white and dark meats compared with the control diet. Adding ALA increased the ALA, LCω-3 fatty acid and total polyunsaturated fatty acid (PUFA) ω-3 fatty acid content of both meat types, except in the case of the white meat of the birds fed rapeseed. Chia seed gave the highest total PUFA ω-3 increase, yielding 157 and 200% increases for the dark and white meat, respectively, compared with the control. The ω-6:ω-3 and SFA:ω-3 ratios dramatically improved in both types of meat when chia seed, chia meal or flaxseed was added to the diet. The study also showed that not all ALA-rich seeds are biologically equivalent sources in terms of producing ω-3 enriched broiler meat. Chia proved to be superior to the other sources examined in this trial. Key words: Chia seed, flaxseed, rapeseed, omega-3, alpha-linolenic, broiler meat, fatty acid
