“…Brewer's yeast or live yeast has been considered as possible candidates. Yeast has been typically included in calf diets at levels between 0.001% and 1.00%, with some positive effects on DMI, rumen pH and nutrient digestibility (Wagner et al, 1990;Quigley et al, 1992;Callaway and Martin, 1997;Kumar et al, 1997;Dann et al, 2000). Previous studies have explained the beneficial effects of yeast products as due to yeast cell components and fermented products such as organic acids, vitamins and nucleotides.…”

“…Therefore, the administration of an effective dietary immune enhancer or stress reducer may be beneficial for early development of the immune system, strengthening of immune competence and prevention of immune attenuation caused by various stressors of neonatal calves. Although the efficacy of administration of yeast (Saccharomyces cerevisiae) culture on growth performance and production traits has been studied for mature ruminants (Seymour et al, 1995;Kumar et al, 1997;Lesmeister et al, 2004;Daniele et al, 2009), studies a Both authors equally contributed as the first author of this article.…”

The effects of hydrolyzed yeast supplementation on growth performance, health and immune-physiological parameters in neonatal calves challenged with vaccine were investigated. Twelve Holstein calves were started in the experiment at 2 6 1 days of age and were studied for 35 days. Calves were randomly assigned to each of two dietary treatments, a control (CON) and hydrolyzed yeast (HY) group. The calves in the HY group received control calf starter supplemented with 0.2% HY. All calves were given calf starter ad libitum for 5 weeks starting in week 1. Calves were also given whole milk according to a step-down milking protocol. In order to induce immune responses, all calves were challenged with Hog cholera and Erysipelothrix insidiossa live vaccines by intramuscular injection at 3 weeks of age. Growth performance and feed intake were not affected by dietary treatment throughout the experimental period, except that the HY group had significantly higher ( P , 0.05) milk intake than did the CON group at 3 weeks of age. Calves in the HY group showed significantly better ( P , 0.05) fecal and health scores at 3 weeks compared to those in the control group. After vaccine challenge, neutropenia, lymphophilia and thrombocytopenia were observed in the CON group, but calves in the HY group did not show significant changes of leukocytes. The average concentration of serum haptoglobin in the HY group was significantly higher ( P , 0.05) at 1 and 3 days post-vaccine challenge (DPVC) than that of CON group. Feeding HY supplemented calf starter resulted in a higher ( P , 0.05) relative amount of bacterial and viral -specific IgA than in the CON group at 5 DPVC. Although the percentage of CD4 1 T cells was significantly ( P , 0.05) higher in the HY group than in the CON group at 22 DPVC, significant differences between groups after vaccine challenge was not observed during the experimental period. These results suggest that 0.2% HY supplementation in calf starter can improve the health status and immune-related serum protein production and affect blood cell composition in neonatal calves after vaccine challenge.

“…Yeast culture was first used as source of vitamin B in the dairy calf diet (Eckles et al, 1924). Later studies focused on the effects of yeast on the rumen environment in young and adult animals (Erasmus et al, 1992;Yoon and Stern, 1996;Kumar et al, 1997). When calves are supplemented with yeast culture, starter intake increases, which could be attributed to stabilization of rumen pH due to lower lactic acid concentrations (Williams et al, 1991).…”

The objective of this study was to compare the effects of feeding preweaning dairy calves pasteurized milk once or twice a day with or without a combination of yeast-derived products. Holstein heifer calves (n = 48) from The Pennsylvania State University dairy herd were fed 3.8 L of colostrum in 1 feeding and randomly assigned to 1 of 4 treatments (once-a-day milk feeding with or without live yeast culture and mannan-rich fraction and twice-a-day milk feeding with or without live yeast culture and mannan-rich fraction). All calves were fed 6 L of milk daily. Weekly growth measurements and blood samples were taken 3 h after the morning milk feeding for all animals. Growth measurement included body weight, hip width, and withers height. Calf starter refusal was recorded weekly, and a sample was taken to determine dry matter intake. Daily health scores were recorded for each calf using a standard scoring system. Intake, growth measurements, haptoglobin, and health scores data were analyzed using repeated measures analysis with calf included as a random variable. Preweaning average daily gain was 553.4 and 512.1 g/d for calves fed milk once and twice a day, respectively, and we found no difference between treatments. Preweaning calf starter intake was 242.3 and 198.7 g/d for calves fed milk once and twice a day, respectively, and we found no treatment differences. Preweaning calf starter intake was 224.3 and 216.6 g/d for calves fed yeast and without yeast, respectively. Withers height and hip width were similar in calves fed milk either once or twice a day; however, calves fed yeast tended to have greater withers height and hip width than control calves. Haptoglobin concentration as a measure of stress had least squares means of 4.0 and 9.5 ± 3.5 µg/mL for calves fed milk once or twice a day, respectively, and we found no difference among treatments. Scours score and total daily score were similar for calves fed milk once or twice a day. These results suggest that feeding milk once a day can be successfully applied to a calf feeding system and that yeast products may improve structural growth.

“…Agarwal et al (2002) and Tripathi et al (2008) using yeast or yeast culture could not observe improvement on growth or rumen microbial population and rumen fermentation in young ruminants. In contrast, Kumar et al (1997) by feeding yeast culture found increase in rumen bacteria numbers, which modified volatile fatty acid production. When Saccharomyces cerevisiae was included at 20 g/kg diet DM, feed intake and growth enhanced.…”
