a Mammary gland differentiation in 6-week-old animals as assessed by the percent of the mammary gland structure representing terminal end buds (TEB) and alveolar buds (AB) in the 4th abdominal gland for the different treatment groups (60, 180, or 540 mg flaxseed per kg diet referred to as low, middle, and high diet, respectively). Bars indicate the mean ± SD (n = 10). P > 0.05 (Dunnetts test). b Mammary gland differentiation in 10-week-old animals assessed by the percent of the mammary gland structure representing terminal end buds (TEB) and alveolar buds (AB) in the 4th abdominal gland for the different treatment groups (60, 180, or 540 mg flaxseed per kg diet referred to as low, middle, and high diet, respectively). Bars indicate the mean ± SD (n = 10). P > 0.05 (Dunnetts test)
