Supplementation with beta-1,3-glucan improves productivity, immunity and antioxidative status in transition Holstein cows

Supplementation of Live Yeast, Mannan Oligosaccharide, and Organic Selenium during the Adaptation Phase of Newly Arrived Beef Cattle: Effects on Health Status, Immune Functionality, and Growth Performance

“…This is one of the reasons because a better antioxidant status can lead to a greater production of antibodies [ 28 ]. An increased level of antibodies was detected also in the blood of dairy cows fed with LY or yeast-derived products, with a high content of β-glucans during the transition period, testifying their beneficial role in stressful situations [ 29 , 30 ].…”

“…Furthermore, the increase in rectal temperature after the challenge was lower in treated heifers as a result of a better non-specific immune functionality [ 32 ]. The efficacy of β-glucans on non-specific immunity was highlighted also in transition dairy cows, where the direct administration of them markedly reduced serum levels of pro-inflammatory cytokines, as a result of an improved immune functionality and a reduced inflammatory status [ 30 ].…”

“…Increases in fibrolytic, cellulolytic, and lactic acid-utilizing bacteria helped to increase and stabilize the ruminal pH, thus reducing the risk of acidosis and also improving the functionality of the other bacteria, such as the propionate producers [36]. Consequently, the availability of substrates, such as acetate, increased the glucose levels as a result of the maximized digestion of fiber-based feedstuffs [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37]. Moreover, the higher level of propionate, consequent to a better functionality of the other bacteria strains in the rumen, may also play a role in increasing serum glucose concentrations in cattle [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38].…”

In fact, higher propionic acid concentrations can lead to an increased glucogenic potential of the diet of dairy cows fed with yeast derived products [38].…”

Changes in Acute-Phase Proteins in Plasma during the Periparturient Period of Dairy Goats

“…CRP can recognize damaged cells as well as their products, and it can repair the nidus via activating complement. CRP is one of the most rapid reacting APPs, it is induced primarily by IL-1, and the plasma's CRP concentration increases within 4 h after stimulation [16,17]. Lee WC et al reported that CRP can evaluate the general health status of a herd [18].…”
