An experiment was carried out to assess the effect of feed selenium-lysine (Se-Lys) supplementation on milk compositions and serum biochemical indices in Saanen dairy goats in Korea. A total of twelve 36 months old Saanen lactating dairy goats (47±6.21 kg) fed the similar dry matter intake twice a day at 2% of BW (DMI) (10.9% moisture of concentrate and 19% moisture of roughage), milk yield (2.5 kg/d) and parity (2) were randomly selected and subjected for the present study, divided into two groups with six goats in each group. The goats in the control group received rice hulls (10 g/ day) only, and did not receive Se-Lys; goats in the treatment group were fed 0.06 g of Se-Lys with 10 g of rice hulls every day before feeding roughage for six weeks. The milk sample was collected every week, and its compositions were analyzed. The results of the present study showed that there is no significantly increased milk production in Se-Lys treated group goats when compared with control group goats. But, Se-Lys treatment significantly increased the milk protein content (3.98±0.16%), fat (3.72±0.27%), lactose (4.07±0.14%), total solids (12.51±0.28%) and urea (14.42±1.45 mg/dl) content as compared to the control group goats (p<0.05). The somatic cell counts (207,740±28.81 cells/ml) were significantly lower in the Se-Lys treated group than in the control group (p<0.05). Also, the results of the current study showed that supplementation of Se-Lys were significantly decreased the blood biochemical indices of IL-6 (34.34±6.04 pg/ml), TNT-α (0.56±0.22 ng/ml), MDA (5.07±1.03 ng/ml), GPx-1 (9.07±5.17 ng/ml), sCD4 (2.64±1.02 ng/ml) and sCD8 (5.08±2.08 ng/ml) level when compared with without addition of Se-Lys group dairy goats (p<0.05). On the other hand, the selenoprotein P (1,580.18±127.62 ng/ml) level was significantly higher in Se-Lys supplemented group than in the control group (p<0.05). Based on the study results, it was concluded that feed Se-Lys supplementation may improve milk yield with positively improved protein, fat, lactose, total solids, urea content, and biochemical indices without negative effects on milk production traits.
