Effect of mannan oligosaccharides and enzyme utilization on broiler bone parameters
Mineral levels, weight, morphometry, breaking resistance and density of tibia from broilers fed on diets, supplemented or not with mannan oligosaccharides (MOS) and/or enzymes, were evaluated. Seven hundred and fifty birds were used in a completely randomized design and factorial arrangement: 2 x 2...

| description | Mineral levels, weight, morphometry, breaking resistance and density of tibia from broilers fed on diets, supplemented or not with mannan oligosaccharides (MOS) and/or enzymes, were evaluated. Seven hundred and fifty birds were used in a completely randomized design and factorial arrangement: 2 x 2 + 1 – two MOS levels (0 and 0.1%/0.05%, from 1 to 21/22 to 42 days) x two enzyme levels (0 and 0.05%) + positive control diet with antibiotics, totalling five treatments with five replicates. At 42 days of age, 50 birds were sacrificed for tibia analyses. There was no effect (P >0.05) of positive control x factorial or MOS x enzyme interactions on P and mineral matter levels, length and distal epiphysis density. MOS inclusion increased Ca levels (P <0.05). Enzymatic supplementation reduced (P <0.04) the weight, diameter and breaking resistance of tibia. Positive control x factorial interaction was significant (P <0.01) for diaphysis and average density, and birds fed diets with no additives had tibia with lower densities than those from the control treatment. It was concluded that diets with reduced crude protein and metabolizable energy of 2%, supplemented with MOS, can be used for broilers with no negative effects on the bone quality. |
