Title : Effect of broilers chicken diet supplementation with peat additive on growth performance and quality of produced breast meat


The current trends in the production of broiler chickens indicate the need to look for natural solutions that affect the efficiency of production and the quality of meat. The aim of the study was to evaluate the growth performance and quality of broiler chicken meat with the addition of a peat feed additive (PFA) in feed. In this experiment, 1000 pieces of one-day-old Ross 308 broiler chickens were used. Broilers were divided into five groups, each containing 200 birds. The first experimental diet was supplemented with 0,50% of PFA, the second - 0,75%, the third - 1,00%, and the fourth was supplemented by 1,25% PFA. The control group of broilers (CG) was fed a basal diet without the addition PFA supplement. The slaughter yield and the percentage of carcass elements were calculated. Breast muscles were analyzed qualitatively (pH, colour, water-holding capacity, chemical composition). No significant differences were found in growth performance carcass or water-holding capacity features. Addition of peat to feed had a positive effect on higher protein content and lower intramuscular fat in the breast muscles. This demonstrates the potential for the practical use of peat in the production of broiler chickens as a feed additive.

What will audience learn from your presentation?

  • Feed peat additives are of great interest for animal husbandry because they contain organic acids, including humic acids, which, when used in poultry farming, can make a great contribution to the profitability of poultry farming and provide people with healthy and organic poultry products.
  • The addition of peat additives represents a good potential for a significant increase in the quality of the organic meat produced, as well as for a potential improvement in the growth parameters of the poultry.
