Astragalus membranaceus Additive Improves Serum Biochemical Parameters and Reproductive Performance in Postpartum Dairy Cows

Abstract

The purpose of the study was to assess the recovery, immune function, and breeding efficiency of postpartum dairy cows fed Astragalus membranaceus (AM) as a feed additive. The experiment used a completely randomized design. Cows were randomly assigned to two groups: (1) Control group fed total mixed ration (TMR; CON group, n = 15); (2) AM group fed TMR and AM (AM group, n = 15). The AM group was fed 675 g/day. The experimental results showed that compared with the CON group. The breeding interval of the AM group of dairy cows had a tendency to shorten (0.05 < p < 0.1). Plasma viscosity (PV), Plasma fibrinogen (FIB), the red cell aggregation index (TRCAI), Calcitonin (CT), Immunoglobulin M (IgM), and Luteinizing hormone (LH) results of AM group showed a time-treatment interaction (p < 0.05). Furthermore, the result of the study revealed that feeding AM as feed additives to dairy cows during the postpartum period had positive effects on wound recovery, immune function, endocrine regulation, and breeding efficiency.

Grape Seed Extract as a Feed Additive Improves the Growth Performance, Ruminal Fermentation and Immunity of Weaned Beef Calves

“…The serum contents of TP, ALB, GLB, and UN are essential indexes of protein metabolism, and changes in GLU, TG, and NEFA concentrations in serum are closely related to lipid and energy metabolism. Moreover, the ALP, ALT and AST concentrations in serum reflect hepatic functions [38]. In this study, the serum concentrations of TP, ALB, GLB, UN, ALP, ALT, and AST were similar between two groups, suggesting that Gse supplementation did not have negative effects on protein metabolism and the hepatic function of weaned beef calves.…”

“…As important parameters associated with the health of animals, serum biochemistry reflects the physiological metabolism of the body and changes in various organ functions [38]. The serum contents of TP, ALB, GLB, and UN are essential indexes of protein metabolism, and changes in GLU, TG, and NEFA concentrations in serum are closely related to lipid and energy metabolism.…”

Replacing alfalfa hay with amaranth hay: effects on production performance, rumen fermentation, nutrient digestibility and antioxidant ability in dairy cow

“…The changes of serum biochemical parameters which are closely related to the health of animals can be used to evaluate the physiological metabolism of the body and changes in various organ function [ 27 ]. The TP, ALB, GLB, and SUN concentrations in serum reflect protein metabolism, and the serum GLU and TG contents are associated with lipid and energy metabolism.…”

“…The TP, ALB, GLB, and SUN concentrations in serum reflect protein metabolism, and the serum GLU and TG contents are associated with lipid and energy metabolism. Additionally, the ALP, ALT, and AST concentrations in serum are indicators of hepatic function [ 27 ]. In this experiment, the serum concentrations of TP, ALB, GLB, GLU, TG, ALP, ALT, and AST were similar among three groups, indicating that amaranth hay replacement did not have negative effects on health of dairy cows.…”

Effects of Bile Acid Supplementation on Lactation Performance, Nutrient Intake, Antioxidative Status, and Serum Biochemistry in Mid-Lactation Dairy Cows

“…These natural bioactive substances include polyphenolic compounds, antioxidant enzymes, vitamins, etc., which possess strong antioxidant abilities. They can neutralize excess ROS and alleviate the severity of oxidative stress [9][10][11].…”
