An eight week feeding trial was conducted to assess the replacement value of instant noodle waste meal (INW) on the performance characteristic, carcass and haematological parameters of broiler chickens. Ninety, one-day old Anak 2000 chicks were randomly allocated to three treatment groups namely, diet 1 (0% INW), diet 2 (50% INW) and diet 3 (100% INW) in a completely randomized design (CRD). Each treatment group had three replicates of ten chicks each. The inclusion of instant noodle in the diet did not have significant (P>0.05) effect on the performance of the broiler chickens at both starter and finisher phases. The inclusion of instant noodle waste had no significant (P>0.05) effect on the carcass traits and organ weights in broiler chickens. No significant (P>0.05) effect was observed for the packed cell volume, hematocrit, haemoglobin, leucocytes, and mean corpuscular haemoglobin concentration among the treatments. However, mean corpuscular volume and mean corpuscular haemoglobin were significantly (P< 0.05) influenced by the instant noodles inclusion, in the diets. Based on the present results INW could replace maize fraction of the diet partially or wholly without any adverse effect on performance, carcass and health status of broiler chickens.

The present study was conducted to determine the effects of L-arginine supplementation of drinking water on the kidney and liver of Sasso chickens. The study comprised 297 mixed sex Sasso chickens of twelve-weeks old raised in floor pens; the birds were randomly distributed into three treatments and three replicates with thirty-three birds per replicate. The design of the experiment is the completely randomized design (CRD). The birds were fed grower's mash and given different treatment of 0 mg/L (Treatment A at 0% supplementation), 167 mg/L (Treatment B at 50% supplementation), and 334 mg/L (Treatment C at 100% supplementation) of L-arginine supplement in drinking water of 9 L per replicate daily for a period of five consecutive weeks, after which the birds were decapitated. The kidney and liver were removed and taken to histopathology laboratory for histological analysis. The chickens administered 0 mg/L L-arginine (0%) supplementation was without lesions. However, kidney and liver of chickens that received 167 mg/L (50%) and 334 mg/L (100%) supplementation showed explicit damage. There was congestion of the vascular channels in the kidneys and liver of birds that received 167 mg/L of L-arginine and destruction of the glomeruli and tubules in the kidney and peri portal mononuclear inflammatory infiltration in the liver of those given 334 mg/L of L-arginine. This could possibly be a result of the over-expression of nitric oxide which is a vasodilator. These present findings showed that supplementing the diets of Sasso chickens with L-arginine of 50 and 100% have detrimental effect on the structure and functions of the kidney and liver.
