Abstract

A study was conducted to evaluate the effects of replacing processed kidney bean meal (PKBM) for soybean meal (SBM) on egg quality parameters of white leghorn (WL) chicken. A total of 360 eggs (24 per replicate and 72 eggs per treatment), which were collected from a total of 225 chicken (165 layers and 30 cocks) with uniform body weight (BW) and age, randomly distributed into 15 pens and assigned to five treatments, were used for analysis of egg quality. Treatments were SBM substitution by PKBM at 0, 25, 50, 75 and 100% levels for T1, T2, T3, T4 and T5, respectively. Replacement of SBM with PKBM in the diet did not affect albumen height and weight, Haugh unit, yolk index, diameter, weight and height, and shell thickness. The shell weight was significantly (p<0.05) lower for T5 than T1 but yolk color was significantly (p<0.05) higher for T5 than T1. Thus, it can be concluded that 100% (at a rate of 100 g/kg concentrate diet) of PKBM as a substitution for SBM in the diet of layers did not affect the qualities of the eggs except for yolk color and shell weight.

Key words: Egg quality, Haugh unit, kidney bean, soybean meal, yolk color.
