Broiler chickens features of growth with application of a water-soluble phytobiotic growth stimulator on the basis of a combination of essential oils

Abstract

These observations were conducted to study the effect of the complex phytogenic water-soluble stimulator "VATAGANIMAL", the main active substance of which is essential oils of corn, cumin, sesame, rosemary, garlic, thyme on health, feed consumption, features and nature of growth and development of broilers of different sex, as well as the dynamics of changes in physiological processes in chickens in the in the research process on hematological parameters. For the experiment, 200 heads of chickens-broilers of "Cobb-500" cross-breed were selected in the age of 1 day, they were divided according to the principle of analogues into 2 groups – control and experimental. The groups were divided by gender into quantitative chick subgroups. In accordance with the annotation, for the experimental bird group was given the above noted phytoadditive added to the water at a dose of 3 g per 10 liters of water during the growing period of 42 days. All the tested poultry population was kept in the same conditions on deep litter throughout the observation period. The diet for broiler chickens of both groups throughout the growing period was based on complete ration feeds that included starter, growth and fattening periods. Thanks to better growth energy, preservation of broilers from the experimental group, the 7.7% reduction in feed consumption per unit of growth was observed. Beginning from 7 days of age, experimental chickens had 4.5 g (2.45%) higher live weight (188.5 ± 2.70 g) compared to peers of the control group (184.0 ± 2.88 g). The average pre-slaughter live weight of broilers in the experimental group was 2682,1 ± 39,31 g, whereas in the control group this figure was lower – 2472,2 ± 35,16 g. In the six weeks of observation, the average live weight of chickens from the experimental group was almost 8,5% (P<0.001) higher than in peers of the control group. This tendency was characteristic of all sex subgroups.
