The paper presents a study conducted in INCDBNA –BALOTEŞTI on 840 Ross- 308
broilers from hatching to 42 days. The broilers were assigned to 3 groups (control –
C, and two experimental – GLU and GERM), with 280 broilers per group (3 groups
× 2 replicates × 140 broilers). Three compound feeds formulations were used, one
control and two experimental. The control diet was based on corn, soybean meal,
full fat soy and fish meal; in the experimental groups the fish meal was replaced by
corn gluten (GLU); in the other experimental group the full fat soy was replaced by
corn germs (GERM). All compound feeds formulations were isoprotein, isocaloric
and contained equal levels of total and digestible sulphur amino acids, lysine,
calcium and available phosphorus, in agreement with the feeding requirements
recommended for the intensive rearing of these performing hybrids. The broilers
were phased feed with diets according to their age: start (0 – 14 days), growerdeveloper (15 – 28 days) and finisher (29 – 42 days). The monitored productive
parameters were: average daily feed intake (g); body weight evolution by growth
stage (g); feed conversion ratio (g feed/g gain); stock liveability (%); slaughtering
yield and proportion of carcass parts (%), economic efficiency (%).
