| Popis: | Hypothesis is that dietary ajwain (Trachyspermum copticum L.), a phytogenic feed additive, could improve the performance of broiler chickens. On a total of 200 Ross 308 male broilers, during the 42-d growing period (starter: day 1–14; grower: day 15–28 and finisher: day 29–42), varying levels of ajwain alcoholic extract (0, 150, 350 and 450 ppm) were added to the drinking water. A control treatment containing the Virginiamycin antibiotic was also studied. Within each treatment and period, the performances were evaluated and the Economic index calculated. On day 42, two birds per pen were killed and the carcase and organ weights determined. On day 42, on two birds per pen, blood samples were collected on the farm to study the serum parameters. On birds, vaccinated against sheep red blood cells at 14 and 35 days, blood samples were collected at 21 and 42 days of age to determine total Ig, IgG and IgM antibodies and, at day 42, the spleen and bursa of Fabricius were weighed. The microflora on the caecum content was counted. Ajwain extract significantly (p |
