The effect of graded levels of poultry offal in the diet of <i>clarias gariepinus</i>
Abstract
The effect of inclusion of graded levels of poultry offal in the diet of Clarias gariepinus on growth performance and cost effectiveness was determined. Group A (control) was fed with 100% concentrate ration while test group B was fed with concentrate at graded level of inclusion of poultry offal.
There was no significant difference (p<0.05) in the performance of the two groups in terms of growth rate (GR), specific growth rate (SGR), feed conversion ratio (FCR), feed efficiency ratio (FER) and cost effectiveness (CE). Group A however had a higher final mean live weight and total length of 720gms and 47 cm relative to Group B with 465gms and 37cm respectively.
Assessment within group B using FCR, FER, GR, SGR and CE as indices shows that the performance varies within the group. Our study shows that poultry offal is a viable alternative to the more expensive conventional animal protein in fish feeds. An investigation into means of presenting it in an aesthetically acceptable way is hereby recommended.
