Influence of feeding the probiotic Pioneer PDFM® to growing lambs on performances and blood composition

Abstract

The research has been conducted on 48 weaned lambs divided into two groups (C-control and E-experimental) and lasted for 35 days. To lambs in group E the probiotic PIONEER PDFM® was added to the fodder. Lambs in group E had larger average body weights, greater daily weight gain, increased average daily intake and a better feed efficiency, compared to group C.However, differences between groups have not been statistically significant. The concentration of calcium in the blood serum of group E (2.16 mmol/l) on the 35 th day has been statistically lower (P<0.01) compared to group C (2.38 mmol/l). The concentration of chloride was statistically higher in group E (P<0.05) on the 19 th day (104.75:103.38 nmol/L) and statistically lower (P<0.05) on the 35 th day (106.00: 107.33 mmol/L). The concentration of iron in the blood serum was statistically higher (P<0.05) on the 19 th and the 35 th day in group E (26.29 and 33.00 mmol/l) than in group C (21.97 and 29.15 mmol/l); concentrations of phosphorus and potassium in the blood serum were statistically higher on the 35 th day in group E (2.74 and 4.95 mmol/l) than in group C (2.41 and 4.65 mmol/l). Lambs in group E had in the blood sera statistically lower (P<0.01) concentrations of glucose and urea. The activities of the enzymes ALT, AST and CK measured on the 35 th day of fattening were lower (P<0.01) compared to group C. The concentrations of total bilirubin and triglycerides were statistically higher in group E than in group C.

Using ruminally protected and nonprotected active dried yeast as alternatives to antibiotics in finishing beef steers: growth performance, carcass traits, blood metabolites, and fecal Escherichia coli1

“…More net glucose can be transferred from the small intestine to the liver if more starch is digested in the small intestine. Similar blood glucose concentration among the other treatments is consistent with several studies carried out with lambs fed diets containing LY (Antunovic et al, 2005;Ding et al, 2008). Similar blood NEFA concentrations for steers fed yeast and control was expected, but the greater serum NEFA concentration in steers supplemented with ANT may have been caused by lower DMI due to monensin addition.…”

Lactational performance and nutrients digestibility response of dairy buffaloes fed diets supplemented with probiotic (Streptococcus spp.) and fibrolytic enzymes

“…There is conflicting and disputed published material regarding the effects of probiotics on the hematological and blood biochemical parameters of small ruminants. In terms of protein metabolism, sheep fed a probiotic‐supplemented diet had lower blood urea nitrogen (BUN) and urea concentrations (Antunović et al, 2005; Chiofalo et al, 2004; Dimova et al, 2013). It's possible that lamb fed diet supplemented with probiotic lowered BUN levels as a result of better ruminal bacteria's ability to use nitrogen (Bruno et al, 2009).…”

“…Because improved fibre digestion results in increased acetic acid and reduced propionic acid production in the rumen, probiotic supplementation can lower blood concentrations of glucose (Bruno et al, 2009; Zvonko et al, 2005). On the other hand, Sayed (2003) found that probiotic supplementation significantly increased the glucose concentration in lamb and nursing ewes.…”

Use of Lactobacillus farciminis to improve antioxidant status of Tuj lambs

“…Typical probiotics are live bacteria, fungi and yeasts, characterized as being mostly gram positive, and facultative anaerobes that take up residence in the digestive tract and are not absorbed by the host animal. They have antagonistic effects against pathogenic microorganisms (Antunovic et al, 2005). Probiotics have proven their efficacy when utilized as dietary factors for the regulation of gastrointestinal functions.…”
