Abstract
The aim of the study was to determine the effectiveness of the use of various forms of garlic supplementation in broiler chicken rearing. The study involved broiler chickens kept in standard rearing conditions. From the total number of birds in the hen house, 150 one-day-old chicks were selected and assigned to 3 experimental groups (50 birds per group). Each group consisted of 5 replicates of 10 chickens. The birds were weighed at the beginning of the experiment and marked with individual wing tags. The chickens were reared for 42 days. The birds were fed ad libitum with suitable mixtures for the different rearing periods, i.e. starter (day 1-21), grower (day 22-35), and finisher (day 36-42) with unlimited access to water. The addition of two forms of standardized garlic formulation, i.e. garlic granulate administered in the mixture (DG group) and garlic water extract supplied in drinking water (DC group), was the experimental factor. During the experiment, the body weight of the birds was assessed four times: at the beginning of the experiment and at the end of each phase in the nutrition scheme (individual rearing phases). The level of feed consumption, the Feed Conversion Ratio per 1 kg of body weight gain (FCR), and the European Production Efficiency Factor (EPEF) were determined. The mean body weight of the chickens on day 21 was similar. In the subsequent rearing periods, the mean values of body weight differed between the groups. On day 35, significantly higher mean body weight values (p <0.05) were exhibited by birds receiving the garlic supplementation, compared to the non-supplemented control group. Similarly, the slaughter weight (rearing day 42) was higher in the groups receiving the experimental supplement. The increase in the body weight in this period was significant (p <0.05) only in the group supplemented with the garlic water extract. The weight gains in the individual rearing periods differed between the groups. The birds from the DC group achieved the highest gains. The highest mean feed conversion ratio per kg of gain throughout the rearing period was recorded in the control group; it was significantly higher than in the groups receiving garlic, regardless of its form. The calculated European Production Efficiency Factor (EPEF) had the highest value in the group of chickens receiving the garlic water extract. It was by 11.2 and 5.7% higher than in the control group and the experimental group receiving the garlic granulate in the diet, respectively. The garlic supplementation improved the production indices in the broiler chickens. Optimal values of the production parameters were noted in the variant of garlic extract supplementation in drinking water, and this form can be considered suitable for increasing the efficiency of broiler chicken production.
