The influence of mixture of essential oils Digestarom Poultry on the health status and production results of broilers

Abstract

Cilj istraživanja bio je ispitati utjecaj dodatka fitogenog pripravka “Digestarom poultry” (Biomin, Austrija), u hranu brojlera na zdravstveno stanje i proizvodne rezultate. Pokus je proveden na 120 brojlera Cobb 500 provenijencije, podijeljenih u dvije skupine po 60 jedinki. Brojleri su hranjeni standardnim smjesama po preporuci proizvođača hibrida Cobb 500. Pokusnoj je skupini u smjesu umiješan komercijalni fitogeni dodatak (E skupina – pripravak koji sadrži esencijalna ulja kima, mente, klinčića i anisa u količini od 150 g/t). Kontrolna skupina je hranjena smjesama bez dodatka fitogenog aditiva u hranu. Za vrijeme trajanja pokusa praćeni su proizvodni pokazatelji (tjelesna masa, prirast, konzumacija i konverzija hrane) i zdravstveno stanje brojlera. Mjerenja tjelesne mase i konzumacije hrane vršena su na kraju svake faze tova. Tijekom pokusa nije došlo do poremećaja zdravstvenog stanja niti su zabilježeni klinički znakovi bolesti brojlera. Korištenjem fitogenog pripravka “Digestarom poultry” postignuti su bolji proizvodni rezultati pokusne skupine brojlera u odnosu na kontrolnu skupinu. Utvrđeno je da je prosječna tjelesna masa brojlera pokusne skupine bila numerički veća od kontrolne skupine u razdoblju tova do 10. dana, a nakon 20. i 42. dana pokusa i statistički značajno veća (p<0,05). U svim fazama tova, kao i za cijeli period tova pokusna je skupina imala značajno veći prosječni prirast, manju ukupnu konzumaciju hrane i bolju konverziju hrane.

The aim of this study was to investigate the influence of the phytogenic additive, the commercial preparation “Digestarom poultry” in broilers’ diet on health and performances of broilers. The experiment was conducted on a total of 120 Cobb 500 broilers, divided into two groups of 60 individuals. Broilers were fed on standard feed mixtures as recommended by the manufacturer, of Cobb 500 hybrids. The experimental group was fed on a mixture with the commercial phytogenic additive (E group - phytogenic additive containing essential oils of cumin, mint, cloves and anise in the amount of 150 g/t), while the control group have not phytogenic additives in the feed. During the experiment, production parameters (body weight, weight gain, consumption and feed conversion) and state of health of the broilers were monitored. Control measurements of body weight and feed consumption were carried out at the end of each phase of fattening. During the experiment, there was no disturbance of health condition and/or appearance of clinical signs of disease in broilers. By using the commercial preparation “Digestarom poultry”, better production results in the experimental group were achieved compared to the control group. It was found that the average body weight of broilers of the experimental group was higher than in the control group during the 10 days of the experiment only numerically, but after 20 days and 42 days of the experiment it was significantly higher (p<0.05). At all stages and during the whole period of fattening, the experimental group had significantly higher average weight gain, lower total feed consumption and better feed/gain ratio.
