The influence of probiotic additives or multienzyme composition on blood biochemical parameters and milk quality of Lithuanian Black-and-White cattle

Abstract

The aim of the study was to determine the effect of Saccharomyces cerevisiae, multienzyme composition supplementation on milk yield, quality, blood biochemical parameters of Lithuanian-Black-and-White cows. For this reason 28 cows were divided into four groups (three experimental and one control) each with seven cows fed balanced ration (control group) and following experimental groups: addition of 40g supplement of live yeast with organic selenium (group A); 40g supplement of live yeast with aromatic additives (group B); and 0.2g supplement of multienzyme composition (group C) during a 90 days period. The study showed that milk yield was 2.64%, 1.75%, 1.4% higher in groups A, B, C respectively, comparing with the control group. The milk SCC in experimental groups were lower comparing to the control group. The percentage of milk fat was significantly higher in group A -0.33%, B -0.31% and C -0.16% comparing with the control group. All used additives ensure positive dynamics of investigated biochemical parameters in cattle blood. The results indicated that probiotic additives and multienzyme composition supplementation to dairy cows increased cows productivity and milk fat as well. Probiotic additives supplementation decreased SCC values in milk. Palavras-chave: vaca leiteira, probiótico, fermento, produção de leite, sangue

Positive effects of dietary supplementation of three probiotics on milk yield, milk composition and intestinal flora in Sannan dairy goats varied in kind of probiotics

“…In particular, live probiotic bacteria are thought to have many positive impacts on animal health, such as reducing susceptibility to pathogen infection (Piewngam et al, 2018), increasing body weight (Hu et al, 2019), improving the digestibility coefficients of nutrients (Bhatt, Sahoo, Karim, & Gadekar, 2016) and increasing feed intake (Du et al, 2018). Furthermore, Dailidaviciene et al (2018) reported that dairy cows fed probiotic additives had significantly higher milk fat than control group animals. For example, studies of cows indicate that supplementation with probiotics may increase milk yield (Piva, Belladonna, Fusconi & Sicbaldi, 1993;Salvati et al, 2015).…”

Messias et al (2018) found that probiotics significantly increased the levels of milk protein in treated animals compared with controls.…”
