dc.description.abstract | One experiment was conducted to investigate the benefits of a multi-enzyme complex, containing carbohydrases (from Penicillium funiculosum) and
phytase (bacterial 6-phytase) activities, on the performance and bone mineralization of broiler chickens fed
corn-soybean meal diets. A total of 2,268 male broilers were allocated to 9 treatments, replicated 6 times,
in a randomized complete block design from 1 to 43
d. A positive control (PC) diet formulated to be adequate in nutrients and 4 reduced nutrient diets (NC1 to
NC4), with gradual decrease on AME, CP, and digestible amino acids (CP-dAA) and available P (avP) and
Ca contents, with or without enzyme supplementation,
were tested. The nutrient reductions applied were NC1
(−65 kcal/kg, −1.5% CP-dAA) and NC2 (−85 kcal/kg,
−3.0% CP-dAA) both with −0.15 percent point avP
and −0.12 percent point Ca and NC3 (−65 kcal/kg,
−1.5% CP-dAA) and NC4 (−85 kcal/kg, −3.0% CPdAA) both with −0.20 percent point avP and −0.16 percent point Ca. Supplementation of the NC diets
with the enzyme complex increased ADFI (P < 0.001),
ADG (P < 0.001), and reduced feed:gain (P < 0.01).
The magnitude of the enzyme effect in increasing feed
intake and weight gain was greater for the diets with
greatest reductions in avP and Ca. Enzyme supplementation increased (P < 0.001) feed intake of birds fed on
NC diets close to the level of feed consumption of the
PC. Enzyme supplementation to NC diets resulted in
all cases in lower (P < 0.05) feed:gain than the PC. Enzyme supplementation to NC1 and NC3 diets restored
bone mineralization to that of the PC, whereas ash
and Ca with NC2 and NC4 diets and P with NC4 diet
remained lower (P < 0.05). These results suggest that
the dietary supplementation with a multi-enzyme complex containing nonstarch polysaccharide enzymes and
phytase is efficient in reducing the P, energy, protein,
and amino acid specifications of corn-soybean meal diets. | ca |
