Eggs production and quality of eggs from hens fed with concentrate containing extracted butterfly pea plant protein.

Abstract

The experiment aimed to study the effect of mixing Butterfly Pea Plant Extract (BPPE) in laying hens concentrate. BPPE was prepared by chopping whole plant with water, collection the squeezed liquid, and warmed at 60 degree C in order to collect the floated protein-fat curd for drying. BPPE had 45.1%CP and 11.5% EE. Under a completely randomized design (CRD) hens were arranged into 4 treatments using 0, 0.5, 1.0, and 1.5% BPPE in concentrates. 80 laying hens were randomly put into 4 replications using 5 hens per experimental unit. The experiment lasted for 2 months. All groups of hens consumed 84 – 93 gram feed per day and produced eggs at 63-74%, which were both not different among groups. Eggs shape index found to be 76-77%, and the internal quality (Haugh unit) were 75-84%, both were not significantly different (P>0.05). Albumen concentration indicated by the stability of albumen on glass plate showed that eggs from hens received 1.5% BPPE concentrate was higher (P<0.05) than the group fed non BPPE included concentrates. The protein content of mixed egg yolk-albumen was in the same trend, higher in groups fed BPPE included concentrates. Therefore, BPPE can be used up to 1.5 % for mixing in concentrate for laying hens. The color of eggs yolk was simultaneously improved.
