Bottom Line: It is concluded that birds can be fed with maize replaced with up to 50% hydrolyzed cassava peel in chicken feeds without serious deleterious effects and that the wastes have useful products in animal nutrition.Also, the replacement added economic in chicken production.The hydrolysis has led to a reduction in the potency of cyanide in the peel thereby making it a safe and possible candidate in the production of chicken feeds.

ABSTRACT
The purpose of this study is to investigate the effect of hydrolysed cassava peel inclusion as a replacement for maize in broiler chicken feedstuff on the histology of the internal organs of broiler chickens. Thirty six, two weeks old unsexed broiler chickens were used for the study in a feeding trial of forty two days. The chickens were randomly allocated to six dietary treatments A - F using a completely randomized design. Each treatment group contained two replicates of three broiler chickens. Group A chickens (A1 and A2) were fed with the control diet (0% hydrolyzed cassava peel as main carbon source). Groups B-E (in replicates 1 and 2) were administered with experimental diets containing 25%, 50%, 75%, 100% of hydrolyzed cassava peels respectively replacing maize while group F (F1 and F2) were fed with diet containing 100% unhydrolyzed cassava peels replacing maize as the main carbon source. Feed and water were supplied ad libitum for the six weeks feeding trials period. Vaccine and drugs were administered as at when due. At the end of the third week, two replicate per group were fasted for twelve hours and slaughtered. Samples of liver, kidney and heart were collected and tissue samples were taken for histological examinations. All the chickens in group F that fed on unhydrolyzed cassava peel recorded 100% mortality within the first six days of the feeding trials while those in groups A to E recorded 0% mortality. Histology of the kidney, heart and liver showed increasing mark of coagulative necrosis, degeneration of the hepatocytes and vacuolations due to the shrinking of the hepatocellular and cardiac tissues as the cassava inclusion level increases in feed. It is concluded that birds can be fed with maize replaced with up to 50% hydrolyzed cassava peel in chicken feeds without serious deleterious effects and that the wastes have useful products in animal nutrition. Also, the replacement added economic in chicken production. The hydrolysis has led to a reduction in the potency of cyanide in the peel thereby making it a safe and possible candidate in the production of chicken feeds.

Mentions: The photomicrograph of the organs (Kidney, Liver and the Heart) of the control birds and those fed on experimental feeds 0%, 25%, 50%, 75% and 100% for groups A to E respectively are as shown on pages 10–12. Group A chickens were fed control diets while Groups B – E were fed experimental diets respectively. The kidneys of the birds fed with control diet in A were normal with black arrows showing glomerulus and vein as shown on Figure 1 while photomicrographs of Figures 2 and 3 reveals normochromic, mildly degenerated, hypercytic kidney tissues with black arrows showing degenerating glomeruli while white arrows are showing vacuolations due to the shrinking of the internal organelles. Figures 4 and 5 show degenerating glomeruli in hyperchromic, mildly degenerated, hypercytic kidney tissue with white arrows showing more visible vacuolations and black arrows showing degenerating glomeruli. Photomicrograph of the liver in Group A chickens revealed normal hepatocellular tissue with radiating hepatic cords and intact intestinal mucosa, muscle wall and serosa without any visible damage (Figure 6). Figures 7, 8, 9 and 10 however reveal mildly to moderately degenerating hepatocellular tissues with black arrows showing vacuolations while white arrows show the degenerating cells. Figure 11 shows the photomicrograph of the heart of chicken fed control diet A with normal cardiac muscle. Figures 12, 13, 14 and 15 show the photomicrographs of the heart of chickens fed experimental diets in groups B to E respectively revealing normochromic, normocytic tissue (Figures 12 and 13) and hyperchromic mildly degenerated cardiac tissues (Figures 14 and 15). The arrows indicate more visible vacuolations in the heart tissues.Figure 1
