objectives: to assess the effect of flaxseed on rat milk creamatocrit and its contribution to offspring weight gain during lactation. methods: the study was conducted with 22 lister hooded rats divided into two groups: control group (cg, n = 11), which received a casein-based diet with 17% protein, and flaxseed group (fg, n = 11), which received a 25% flaxseed diet supplemented with 14% casein, totaling 17% protein. food consumption was controlled per individual cage and litter size. maternal milk creamatocrit and offspring weight variation until weaning age were also evaluated. results: fg was similar to cg concerning food intake (fg = 76.46㊣31.87 g; cg = 76.7㊣33.36 g; p = 0.9613) and equivalent to cg concerning litter size (fg = 4.94㊣2.34; cg = 5.5㊣3.19; p = 0.435). the same was found for milk fat content (fg = 18.4㊣4.76; cg = 15.3㊣6.03; p = 0.204) and total energy value (fg = 212.92㊣46.4; cg = 181.1㊣60; p = 0.1964). fg was similar to cg both in offspring body weight at weaning (fg = 37㊣6.96 g; cg = 32.6㊣7.5 g; p = 0.1817) and in weight gain (fg = 31.8㊣7.0 g; cg = 27.7㊣7.5 g; p = 0.2104). conclusion: a total of 25% flaxseed promoted an adequate offspring growth.
