dc.description.abstract S-a studiat componenţa microflorei intestinale la puii de găină sub acţiunea unor produse cu efect probiotic şi antibiotic. Puilor de găină de rasa Rhode Island (4 loturi a câte 20 de pui fiecare) le-au fost administrate: biomasă produsă de streptomicete (1g/kg), lichid cultural de streptomicete (1ml/pui), oxitetraciclină în apa de băut(1 g/l apă) şi preparatul Immunobak (0,2 g/pui). La vârsta de o zi, 15, 55 şi 75 de zile au fost prelevate lavaje de la nivelul mucoasei intestinale şi au fost efectuate însămânţări pe medii nutritive (Bismut sulfit agar, agar peptonat, Endo, Levin) pentru evaluarea indicilor microbiologici. S-a stabilit că odată cu vârsta puilor creşte şi încărcătura bacteriană. Numărul de colonii obţinute din lavajele colectate de la pui la vârstele de 55 şi 75 de zile este aproximativ identic, cu o marjă a variaţiei nesemnificativă. Microflora intestinală este alcătuită într-o proporţie mai mare, din bifidobacterii, streptococi şi E. coli, mai puţin reprezentative fiind coloniile de tulpini de Bacteroides şi Enterococcus. en_US
dc.description.abstract The composition of intestinal microflora in chickens under the influence of some products with probiotic and antibiotic effect was studied. The chickens of Rhode Island breed (4 groups of 20 chickens each) received: biomass produced by streptomycetes(1g/kg), culture liquid ofstreptomycetes(1ml/chicken), oxytetracycline in the drinking water (1 g/l of water) and the preparation Immunobak (0.2 g/chicken). Atthe age of 1 day, 15, 55 and 75 days,lavages of intestinal mucosa were taken and inseminations on nutritive media were performed (Bismuth sulfite agar, peptone agar, Endo, Levin) with the purpose of assessing microbiologicalindicators. It was established that bacterial load increases with age of the chicks. The number of colonies obtained from the lavages collected from chickens at the age of 55 and 75 days are almost identical, with a small insignificant variation. Intestinal microflora consists of a great proportion of bifidobacteria, streptococci and E. coli, the colonies of Bacteroides and Enterococcus strains being less representative.
