Název v původním jazyce

Retention of protein and fat in the meat of fast and slow-growing chickens fattened to higher age.

Popis výsledku v původním jazyce

In trial with fast growing cockerels (FG) and slow growing (SG), production parameters and content of dry matter (DM), protein (P) and fat (F) in the breast (BM) and thigh meat (BM) were investigated within the age interval from the 5th to the 18th week.Chickens were fed a mixture containing high level of CP. In FG group, changes in the content of DM, P and F in the BM, and DM and fat in TM were not significant, the content of protein in TM increased significantly with the age. In SG group significantly increased content of DM and F in BM, other values did not changed. In FG chickens, the weight of BM, TM and the P content in the BM and TM increased by 25; 20; 28; and 24 %, and in SG group by 18; 13; 26; and 14 % faster and the growth of the F contentin BM of FG and SG groups slower by 16 and 30 % than their live BW, resp. In FG group, the relative increase of fat content in TM was lower by 8 % while in SG group it was higher by 9 % than the growth rate.
