초록

The study was conducted to evaluate effects of dietary phytase on growth performance, meat quality, nutrient digestibility and phosphorus utilization in broilers. Breeding experiment, a total of 480 Arbor acre broilers chicks of 2 days old were randomly divided into 3 treatments with 8 replicates of 20 birds each. The treatments were CON(basal diet), LP(Low phosphorus diet) and CP(Low phosphorus diet+0.05% coated phytase). Metabolism experiment 2, a total of 96 Arbor acre broilers chicks of 5wks old were randomly divided into 4 treatments with 8 replicates of 3 birds each. The treatments were CON(basal diet), LP(Low phosphorus diet), NP(Low phosphorus diet+0.05% normal phytase) and CP(Low phosphorus diet+0.05% coated phytase). Weight gain was significantly increased in CON treatment than LP and CP treatments(P<0.05). F/G in CON and CP treatments was improved than LP treatment(P<0.05). Calcium contents in blood was increased for CP treatment compared to LP treatment(P<0.05). However, Phosphorus in blood was higher in CON treatment compared to LP treatment(P<0.05). Carcass and CIE a* of breast meat were significantly increased in CON treatment than LP treatment(P<0.05). WHC of breast meat was improved for CON and CP treatments compared to LP treatment(P<0.05). Digestibilities of dry matter and nitrogen were higher in CON treatment compared to LP treatment(P<0.05). Crude ash was greater in CON treatment than CP treatment(P<0.05). Calcium was improved for broiler fed CON and CP treatments compared with LP treatment(P<0.05). Digestibility of phosphorus was significantly reduced in LP treatments than CON and CP treatments(P<0.05). CP treatment was significantly increased their dry matter intake, calcium intake and nitrogen retention compared to LP treatment(P<0.05). CON treatment was significantly increased their phosphorus intake and phosphorus retention compared to other treatments(P<0.05). Calcium retention was higher in CON and CP treatments than LP treatment(P<0.05). Phosphorus excretion was significantly reduced in NP treatment than CON and LP treatment(P<0.05). Nitrogen and calcium excretion were significantly reduce in CON treatment than other treatments(P<0.05). In conclusion, Phytase treatment improved performance and decreased calcium and phosphorus excretion in broilers.

Breeding experiment, a total of 480 Arbor acre broilers chicks of 2 days old were randomly divided into 3 treatments with 8 replicates of 20 birds each. The treatments were CON(basal diet), LP(Low phosphorus diet) and CP(Low phosphorus diet+0.05% coated phytase). Metabolism experiment 2, a total of 96 Arbor acre broilers chicks of 5wks old were randomly divided into 4 treatments with 8 replicates of 3 birds each. The treatments were CON(basal diet), LP(Low phosphorus diet), NP(Low phosphorus diet+0.05% normal phytase) and CP(Low phosphorus diet+0.05% coated phytase). Weight gain was significantly increased in CON treatment than LP and CP treatments(P<0.05). F/G in CON and CP treatments was improved than LP treatment(P<0.05). Calcium contents in blood was increased for CP treatment compared to LP treatment(P<0.05). However, Phosphorus in blood was higher in CON treatment compared to LP treatment(P<0.05).

Calcium was improved for broiler fed CON and CP treatments compared with LP treatment(P<0.05). Digestibility of phosphorus was significantly reduced in LP treatments than CON and CP treatments(P<0.05).
