Abstract
A study was conducted to evaluate the effects of feeding processed kidney bean meal (PKBM) by replacing soybean meal (SBM) on fertility, hatchability, embryonic mortality and chick quality of white leghorn (WL) hens. A total of 225 white leghorn hens (195 layers and 30 cocks) with uniform body weight (BW) and age were randomly distributed into 15 pens and assigned to five treatments (i.e., T1, T2, T3, T4, and T5). A total of 360 eggs collected from all the treatment birds were used for the analysis. The feeds of the treatments were SBM substituted 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 the fertility, hatchability, embryonic mortality, chick length, chick weight, and chick quality by visual score. As no difference is observed, 100% replacement of SBM by PKBM (dosed at 100 g/kg concentrate diet) is possible.
Highlights
The cost of poultry feed is very high and it rest treatments
Visual assessment of chick quality is lower for accounts for 60-70% of the layer production cost Wilson treatments containing higher proportion of PKBM than and Beyer (2000)
The price of treatments containing lower proportion of PKBM. As it affects the quality of chicks at 100% replacement, it is only up to 75% replacement of soybean meal (SBM) by PKBM is possible without having significant negative effect on chick quality
Summary
The results of the chemical analysis of on the quality standards described by North (1984). ingredients used and nutritional composition of the a chick that was not malformed, physically ration for each treatment are given in Table 3 and 4 active, stands up well, and looks live has been taken as respectively. The chick’s length was taken of kidney bean used in the present study was by stretching the chicks on the table and taking the comparable to that reported by Arija et al, (2006), length from the tip of the beak to the middle toe by a Emiola (2011), Sai-ut et al, (2009), Audu and Aremu ruler. For this reason, the energy content decreased with indicated that visual scoring of chicken was not increasing level of processed kidney bean. Energy and protein content of all rations assessment showed that the quality of chicken is better ranged within the recommended level for layers. The energy of compound ration is inactive at their day old age This assessment was the same with that used by Zebiba (2012) and Senayt et supported by length and weight of chicks that indicated al., (2011) in their experiment for the same bird in the significant differences among treatments.
