WEIGHT GAIN, g (1-21 days): NORMAL QUALITY CORN -During the period of 1 to 21 days old, the chicks that received additives in their ration, presented higher weight gain when compared to basal feed (P<0.05). Among the treatments containing BIOLASE, the best results of weight gain were obtained with 500 g/ton. of product. LOW QUALITY CORN -Using low quality corn, there was an improvement on weight gain with the inclusion of pre-biotics and avilamycin, and the treatments containing 0.5 kg of BIOLASE (722g), avilamycin (718g), and 2 kg Bio-Mos (718g) stood out as the best results.

FEED CONVERSION (1-21 days): NORMAL QUALITY CORN - The usage of additives improved feed conversion (P<0.05) and the treatments containing BIOLASE 0.5kg (1.557), BioMos 2 kg (1.557) and avilamycin (1.554) were the best results. LOW QUALITY CORN - In this case the improvement on feed conversion was even more important. The best result among all was found with BIOLASE 0.5 kg.

WEIGHT GAIN, g (1-42 days): NORMAL QUALITY CORN -Using additives improved the weight gain (p<0.05), and the best performance was obtained with BIOLASE 0.5 kg, BioMos 2 kg and avilamycin. LOW QUALITY CORN -As with normal quality corn, the weight gain was higher when additives were used (p<0.05) and the best results were achieved when using BIOLASE 0.5 kg, BioMos 2 kg and avilamycin. FEED CONVERSION (1-42 days): NORMAL QUALITY CORN & LOW QUALITY CORN -Feed conversion was better when additives were used (p<0.05). The best results were achieved when using BIOLASE 0.5 kg, avilamycin and BioMos 2 kg.

YIELD FACTOR (1-42 days): (YF=DAWG x livability x alimentary efficiency x 100) DAWG= daily average weight gain, Livability = 100/mortality, Alimentary Efficiency = 1/ feed conversion Table 05 – Yield factor of broilers, 1-42 days old. Yield Factor Treatment Normal Quality Corn Low Quality Corn Average Blank Feed (BF) 289c 273c 281c BF + Avilamicine 305a 290a 297a BF + BIOLASE (.5kg/t) 303a 295a 299a BF + BIOLASE (1kg/t) 300ab 285ab 293ab BF + BIOLASE (2kg/t) 298b 281b 289b BF + BioMos (2kg/t) 300a 293a 296a Average 299A 286B CV(%) 2,74

YIELD FACTOR (1-42 days): NORMAL QUALITY CORN -The yield factor increased (p<0,05) on broilers which received diets containing additives. The best performances were obtained with usage of BIOLASE 500 g, BioMos 2 kg and avilamycin. LOW QUALITY CORN -In this case, the results for YF was even sharper. Once again the best results were obtained using BIOLASE 500 g, BioMos 2 kg and avilamycin.

CONCLUSIONS The usage of additives on broiler feeds improved the performance parameters, such as weight gain and feed conversion when compared to control treatment. The treatment containing BIOLASE 0.5 kg, BioMos 2 kg and avilamycin presented the lowest feed conversion rate (p<0.05). The treatment containing BIOLASE 0.5 kg, BioMos 2 kg and avilamycin presented the best yield factor (p<0.05). The right inclusion rate for BIOLASE is 0.5 kg per ton of feed, under present test conditions.
