國産 제2인산 칼슘 添加가 브로일러의 生産性 및 燐의 利用率에 미치는 影響 = Effects of Locally Produced Dicalcium Phosphate on the Performance and Biological Availability by Broiler Chicks

다국어 초록 (Multilingual Abstract)

This experiment was carried out to compare biological availability of phosphorus(P) in locally produced dicalcium phosphate(DCP), tricalcium phosphate(TCP) and sodium acid phosphate (SAP) with 210 broiler-type chicks(Arbor Acres). Chicks were divided into 7 treatments consisted of DCP_1(low), DCP_2(high), TCP_1(low), TCP_2(high), SAP_1(low), SAP_2(high) and Control group for a period of 4 weeks.
The results obtained are summarized as follows:
1. Liveability of Control, DCP_1, DCP_2, TCP_1, TCP_2, SAP_1 and SAP_2 were 90.0%, 96.7%, 96.7%, 93.3%, 93.3% 96.7% and 96.7%, respectively.
2. Body weight gain, feed intake and feed efficiency for 4 weeks feeding period were not significantly affected by the source of phosphorus supplements. However, it was found that chicks received DCP gained more body weight than the birds fed TCP or Control diet.
3. The relative biological availability of P in DCP, TCP and SAP fed broiler chicks were 98.1%, 94.23% and 100%, respectively. The results obtained from the present experiment indicated that the availability of P in DCP were better than that in TCP.
