Description
An experiment was conducted to examine the effect of fatty acid concentrate (FAC), as a new source of energy and carnitine on performance, physiological condition and meat quality of broiler chickens. In experiment there were four groups of 80 chickens of cross Hubbard each (males: females=40:40) in age period 0-41 days. 1 group (control) received in during the periods 0-14, 15-28 and 29-41days, sunflower oil (SO) respectively 5.34%, 5.50%, and 6.10%, group 2 received the same amounts of FAC instead SO, 3 group - mixture SO:FAC (50:50), 4 group -FAC + 0,25% carnitine. Final body weight: 1 group = 2574±29 g, 2 group FAC= 2553±27 g 3 group SO + FAC = 2531±34 g., 4 group FAC+0,25 carnitine = 2520±34 g. Feed conversion, digestibility of nutrients, blood hematology and biochemistry, the condition of organs, meat quality and cutting of carcass of chickens on FAC had no any differences from the same signs in chicks on SO. Carnitine had a positive effect on chicken growth only in the period 0-14 and less 15-28 days; in the period 29-41 days daily gain was below, than that in 1-3 groups. Canitine reduced the content of liver fat. Outcome: FAC is a satisfactory source of energy, comparable with vegetable oils. The price of FAC is 30% lower in comparison with sunflower oil and soybean oils, therefore its use in broiler poultry farming instead of vegetable oils will be of great economic importance
