Feed additive based on vegetable raw material waste for poultry feeding
This paper highlights the results of the use of a coniferous energy supplement (CES) in the amount of 0.8%, by weight of feed in the compound feed of Lohmann Brown male chicks. A scientific and economic experiment to study the effectiveness of a coniferous energy supplement was carried out in the vivarium conditions of the Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine according to a standard methodology. When the birds reached the age of 70 days, the coniferous energy supplement was included in the complete feed of the birds of the experimental group. There was a tendency to increase the live weight of males by 2.7% relative to the control value. Using a coniferous energy supplement at the age of 90 days resulted in the increased live weight of the experimental birds by 6.3% (P≥0.95) relative to the control indicator. The inclusion of a coniferous energy feed additive in the diets for male chicks in the amount of 0.8% by weight of the compound feed contributed to an increase in gross live weight gain by 7.1% compared to the control. The introduction of a coniferous energy supplement into the complete feed for males contributed to an increase in the average daily gain in their live weight by 7.2% compared to the control. The survival rate of the poultry population when using a coniferous energy supplement reached 100.0%, which exceeded the control value by 2.7%. The average daily feed consumption by the chickens of the experimental group was slightly higher by 2.4%. For the entire period of the experiment, males that received a coniferous energy supplement consumed a little more feed - by 2.7%. At the same time, the feed conversion rate per 1 kg of live weight of males was reduced by 6.5%.Keywords: Poultry farming, male chicks, coniferous energy supplement, live weight gain of poultry, survival rate, feed conversion rate.
