Usability of Fermacto prebiotic in feeds for common carp (Cyprinus carpio L.) fry
Summary. The studies have determined the effect of Fermacto prebiotic addition in feeds, on the growth and food conversion ratio in common carp fry. Four types of granulated experimental feeds were prepared, from which three feeds contained different amounts of Fermacto prebiotic (F1 – 1.0 g/kg, F2 – 2.0 g/kg, F3 – 3.0 g/kg) and a control feed K – without a prebiotic. During a 50-day growth test, the fish receiving prebiotic feeds showed significantly higher mean individual body weight (p ≤ 0.05) in comparison with the control group. The best effects have been obtained in the variant F3, where the specific growth rate (SGR) was 2.44%, feed conversion ratio (FCR) was 1.21, protein efficiency ratio (PER) was 2.18, and the values significantly differed from the remaining variants. The values of the coefficients of feed protein retention were contained in the interval: 2.80-4.53%, while the values of fat retention coefficients ranged from 8.97 to 15.07%. During the growth test, no fish losses were recorded. Feeding of carp fry with feeds containing an addition of Fermacto prebiotic improves the rearing results; the optimal addition of prebiotic is 3 g of the preparation per 1 kg of feed.
