“…Previously, we have determined crude protein and crude fat and lactose content in the study colostrum samples, of which crude protein was elevated in colostrum from SBP‐fed sows and lactose in colostrum from LNC‐fed sows (Grześkowiak et al, 2022a). In addition, we have assessed the colostrum samples for biogenic amines, immunoglobulins and C. difficile toxin‐neutralising IgG antibodies (Grześkowiak et al, 2022a). Here, total biogenic amines were higher in colostrum from sows fed SBP than LNC (Grześkowiak et al, 2022a).…”
