CHEMICAL COMPOSITION OF MUSCLE AFTER POLLEN APPLICATION IN NUTRITION OF BROILER CHICKENS

Abstract

Principle purpose of this study was to monitor the chemical composition of breast and thigh muscular part of chickens of hybrid combination Ross 308 and to verify the differences due to use of pollen extract in feed mixture at a dose of 400 and 800 mg.kg-1 during the feeding of 42 days. We did not find significant differences (P≥0.05) in followed chemical compounds of thigh muscle with the skin and subcutaneous fat between the groups with and without application of pollen extract: in contents of water (68.49-70.12 g.100g-1), protein (18.82-18.98 g.100g-1), fat (9.96-11.53 g.100g-1) and in energy value (692.20-752.36 kJ.100g-1). Significant differences (P≤0.05) were found only in protein content of breast muscle between the control group (23.96 g.100g-1) and experimental group I (23.28 g.100g-1). Values of water content (73.97-74.32 g.100g-1), fat content (1.07-1.40 g.100g-1) and energy (441.65-446.64 kJ.100g-1) in breast muscle between the evaluated groups were balanced (P≥0.05). The results show that pollen extract at the concentration used in feed mixture did not effect basic chemical composition of the most valuable parts of the chicken Ross 308 carcass and we can apply it in their nutrition. Application at a dose of 800 mg.kg-1 seems to be more positive.doi:10.5219/190
