The proximate composition, pepsin digestibility, gross energy and macro mineral contents of 12 composite samples of poultry offal meal produced in Sri Lanka were analyzed. The average dry matter, ash, crude protein, crude fiber, ether extract, in vitro pepsin digestibility and gross energy of poultry offal meal were 92.3, 6.9, 48.9, 2.1, 32.4, 83.8% and 23.6 MJ kg-1, respectively. The average Ca, P and Mg contents were 2.36, 1.10 and 0.09%, respectively. The replacement value of poultry offal meal for soybean meal and the effect of supplementation of poultry offal meal by dietary enzymes (Solid state fermentation and Lipase) on the performance of Japanese quails fed isocaloric and isonitrogenous diets were studied in two experiments. Unsexed Japanese quails (13 days old; N=200) were randomly assigned to twenty groups. In experiment 1, poultry offal meal was incorporated at 0, 2.5, 5, 7.5 and 10% of the diets and fed until 15 weeks of age. In experiment 2, the performance of Japanese quails fed with diets containing 0, 5 and 10% poultry offal meal was investigated. Enzyme effect was tested with diets containing 5 and 10% poultry offal meal. Cost benefit analyses were carried out to find out the most cost effective treatment. The quails fed with diets containing 5 and 10% poultry offal meal produced higher number of eggs (P DOI: http://dx.doi.org/10.4038/tar.v21i3.3306 TAR 2010; 21(3): 293-307 |
