Influence of Prosimbiont E product on growth and haematological indices in young goats

摘要

The aim of the current study was to assess the effect of a nutritive supplement (Prosimbiont E),consisting of minerals, vitamins and live cultures (Lactobacillus plantarum, Streptococcus faecium,Saccharomyces cerevisiae) incorporated in the concentrate mixture (1.5%), on growth andhaematological indices in young goats. For the trial, four experimental groups were set up (n = 11),consisting of Carpathian breed young goats (120-160 days of age), which were ad libitum fed with tworations (R1 and R2) consisting of Lolium hay (60% in R1 and 40% in R2), and a concentrate mixture(40% in R1 and 60% in R2) with 14% crude protein. Average daily gain was significantly higher insupplemented groups compared to their controls, by 18 g (p<0.02) and 37 g (p<0.01) in R1 and R2,respectively. The nutritive supplements administration increased the number of protozoa / ml of ruminalfluid, by 153.2% in R1 and 165.3% in R2. Also, the nutritive supplement doubled the share ofDiplodinium and Dasytricha protozoa genera to the detriment of Entodinium genus. Haematologicalindices were within the reference range of the species, with values of Hgb, RBC, MCV and MCHCsignificantly higher (p<0.05) in the experimental groups compared with the controls.
