| 초록 | This study was designed to investigate the effect of feed selenium-lysine (Se-Lys) supplementation on serum biochemical indices in dairy cattle. A total of twenty four 36 months old dairy cattle (750 ± 6.0 kg body weight) with similar dry matter intake (DMI), milk yield and parity were randomly selected and subjected in this study, divided into four groups with six replicates in each group. The dairy cattle in the control group receive rice hulls (10 g/ day) only, and did not receive Se-Lys; cattle in the treatment group 1, 2, and 3 were fed 0.8, 1.6 and 2.4 ppm of Se-Lys /herd/ every day respectively. The experiment was set up for 2 months. The milk was collected, and its compositions analyzed every week. Results showed that significantly increased milk production when compared with control group cattle (P<0.05). Also, Se-Lys treatment not significantly changed the milk protein content, citrate, FFA, fat, lactose, total solids and urea content as compared with control group cattle (P<0.05). However, the somatic cell counts were significantly lower in the Se-Lys treated group than in the control group (P<0.05). In conclusion, feed Se-Lys supplementation can increase milk yield with its components of milk protein, fat, lactose, total solids and urea content without adverse effects on milk production traits | ||
