“…It is also reported that SC influences the rumen microbial population, resulting in changes in the level of volatile fatty acids (VFAs), which leads to an increase in DMI, milk yield and composition of lactating ruminants (12). DMI and milk production traits were found to be higher in some finding trials (13)(14)(15)(16) and lower in others (17)(18)(19). The use of meta-analytic methods to aggregate published studies with variable results has gained attention in the field of animal agriculture in recent years (20,21).…”

The results of investigations on the impact of Saccharomyces cerevisiae (SC) on performance characteristics of lactating goats are inconsistent. Thus, this study aimed to summarize available evidence on the effect of SC supplementation on dry matter intake (DMI), milk yield and composition in lactating goats using meta-analysis. A systematic search performed on Scopus, Google Scholar and PubMed databases yielded 1,368 studies of which 18 were used for the meta-analysis. Subgroup and meta-regression analyses were performed to explore the sources of heterogeneity in response to dietary SC supplementation. A random-effects model showed that SC had a moderate effect on milk yield [standardized mean differences (SMD) = 0.51; 95% CI: 0.20 to 0.82, p = 0.001] and milk fat (SMD = 0.30; 95% CI: 0.05 to 0.55, p = 0.02) in lactating goats when compared to the controls. Subgroup analysis by SC type indicated that live SC had a large to moderate effect on milk yield (SMD = 1.46; 95% CI: 0.96 to 1.96, p < 0.001) and milk fat (SMD = 0.51; 95% CI: 0.19 to 0.84, p = 0.002), whereas dead SC had a large negative effect on DMI (SMD = −0.82; 95% CI: −1.28 to −0.7, p < 0.001) and a moderate reduction effect on milk yield (SMD = −0.55; 95% CI: −0.99 to −1.96, p = 0.015). We found significant heterogeneity across studies that evaluated the effect of SC treatment on DMI and milk yield in lactating goats and meta-regression analysis explained most of the sources of heterogeneity. In conclusion, pooled results showed that dietary SC supplementation increased milk yield and fat in lactating goats. In addition, subgroup analysis revealed that both live and fermented SC increased milk yield and fat in lactating goats, while dead SC reduced DMI and milk yield.

“…cerevisiae has capable of reducing mycotoxins under soft conditions without using any chemical substances, by binding mycotoxins to its cell wall (Karazhyan, 2017). Many researchers (Aazami, Nasri, Mojtahedi, & Battacone, 2019) have previously reported that S. cerevisiae is able to change the chemical bonds between AFs and food proteins by binding toxins to its own cell wall polysaccharides (such as mannose and glucan) and to transform AFs into less toxic substances by releasing degrading enzymes, lactic acid, ethanol, and CO 2 . This supposition was validated by Shetty, Hald, and Jespersen (2007).…”

“…Based on this information, bread flour can be used as animal feed because the aflatoxin content is still within the safe limits allowed. Aflatoxin content of 25 ppb in feed can still maintain the number of saanen goat leukocytes in a normal state [12]. The number of leukocytes is not too different from the results of research, ranging from 16.60-21.90 thousand/µL [13].…”

This study aims to determine the maximum level of the use of bread waste as a substitute for concentrates on feed utilization by livestock through blood profiles consisting of the amount of hemoglobin, erythrocyte numbers, hematocrit levels and leukocyte numbers. The material used in this study was 15 lactating Etawa crossbreed goats. The experimental design used was a randomized complete block design with 3 treatments and 5 replicates. The feed treatment given was forage and concentrate with a composition of 20:80 with ration treatments namely P1 = Silages 20% + Concentrates 64% + Bread waste 16% + Zeolite 2%, P2 = Silages 20% + Concentrates 56% + Bread waste 24% + Zeolite 2%, P3 = Silages 20% + Concentrates 48% + Bread waste 32% + Zeolite 2%. The observed variables were hemoglobin level (g/dL), erythrocyte count (million/μL), hematocrit level (%) and leukocyte count (thousand/μL). Data were analyzed using analysis of variance. The results showed that the treatment had no significant effect (P>0.05) on the blood profile which included hemoglobin levels, erythrocyte numbers, hematocrit levels and leukocyte numbers. Substitution of 24% bread flour in the ration gave the highest blood profile calculation results among the three treatments. The amount of Hemoglobin (g/dL) of P1, P2 and P3 were 8.88; 10.05 and 8.94. Erythrocyte numbers (million/μL). P1, P2 and P3 were 14.23; 15.92 and 14.59 respectively. Hematocrit levels (%) P1, P2 and P3 were 28.3; 30.98 and 28.72. Leukocyte numbers (thousand/μL) of P1, P2 and P3 were 13.68; 18.00 and 17.3. The conclusion of this study is that bread flour can be used as a substitute for concentrate up to 32% level in the ration and can maintain the blood profile of lactating Ettawa crossbreed goats in a normal state.
