Material type: materialTypeLabelBookPublisher: 2008Subject(s): Department of Poultry ProductionDDC classification: 1018,T Dissertation note: The live weights of different groups (A, B, C, D and E) gave non significant (p<O.05) results but numerically group D and E gave higher values, like wise, dressed weight were higher in group D and E. The dressing % of different groups (A, B, C, D and E) were also non significant (P>O.05). The liver weights of different groups (A, B, C, D and E) at 35 days of age were non significant (P<O.05). However within these groups, birds fed on control diet & DCP imported (group A & D) showed higher liver weights. Similarly there was n0 significant difference (p>O.05) in the heart and gizzard weights of different experimental groups. The result obtained in the course of this study highlighted an invaluable lesson. Regardless of the potential availability of the phosphorus in a feed phosphate, dietary factors and bird condition may result in a dramatically lower effective utilization of the phosphorus. It became evident that the availability of phosphorus was not an inherent property, characteristic of the material being assayed alone, but an experimentally determined value which reflects the absorption and utilization of the phosphorus ingested under the condition of the test.
