Apparent Nutrient Retention and Haematology of Shika Brown Pullet Chicks Fed Three Plant Protein Sources

Abstract

An experiment was carried out to determine apparent nutrient retention and haematological indices of pullet chicks fed three plant protein sources. 243 day old Shika Brown chicks were divided into three treatment groups of 81 chicks subdivided into three replicate groups of 27 chicks. Three experimental diets were formulated to contain groundnut cake (GNC) Full fat soya (FFS) and lablab seed meal (LSM) and fed to the chicks for five weeks (3-8 weeks of age). At the 8th week three chicks per replicate were kept in metabolic cage and fed for faecal sample collection. Feed and faecal samples were weighed, oven dried and analyzed for proximate and mineral composition. Blood samples were collected via wing vein from 1 chick per replicate and stored in EDTA bottles for haematological analysis. Results indicated that retention of dry matter, nitrogen free extract and calcium were similar for chicks fed GNC and FFS but significantly different (P<0.05) from those fed LSM. Crude fibre retention was higher (P<0.05) in chicks fed FFS than those fed GNC and LSM, which were similar. Magnessium and sodium retentions were similar for chicks fed FFS and LSM but significantly different from those fed GNC. Only packed cell volume (PCV) varied significantly between treatment means. Other haematological parameters were similar across treatments and within normal ranges. Nutrients in LSM could be well utilized and safely too as those of GNC and FFS.
