| Keywords: | In an experiment to determine the effect of feeding varying levels of Water Hyacinth Meal (WHM) supplemented with and without exogenous enzymes (Maxigrain®) on the gut morphology, meat yield and sensory properties of laying hens, a total of 216 laying hens aged 24 weeks and 4 weeks in lay were used. Six experimental diets were formulated based on the Completely Randomized Design model using a 2 x 3 factorial arrangement made up of two levels of enzyme (No enzyme, With enzyme) and three dietary inclusion levels of WHM (0, 10 and 20 %). At the end of the feeding trial, two birds per replicate were randomly selected, kept off feed for 12 hours, slaughtered, defeatheded, eviscerated and dressed. The meat of the breast and thigh of each replicate sample were then selected for sensory evaluation. All parameters were expressed as percentage of live weight. Results showed that there were no significant (p>0.05) differences in live weight (LW), slaughter weight (SW), defeathered weight (DW), eviscerated weight (EWT) and dressed weight (DW) between birds fed diets supplemented with exogenous enzymes and those without exogenous enzyme supplementation; and between birds fed the varying dietary inclusion levels of WHM (0, 10 and 20 %). Also, there were no significant (p>0.05) differences in the weight of the head, neck, breast, back, thigh, drumsticks, wings and shanks between the birds fed diets supplemented with exogenous enzymes and those without exogenous enzyme supplementation; and between the birds fed the varying dietary inclusion levels of WHM (0, 10 and 20 %). Of all the internal organs assessed, only the gizzard weight was significantly (p<0.05) higher for the non-enzyme-supplemented diets than for the enzyme-supplemented diets. There were no significant (p>0.05) differences in appearance, flavour, juiciness, tenderness and overall acceptability between the meat of birds fed diets supplemented with exogenous enzymes and those without exogenous enzyme supplementation; but the meat of birds fed 10 and 20 % dietary inclusion levels of WHM had significantly (p<0.05) higher scores for tenderness and general acceptability than the meat of birds fed the 0 % dietary inclusion level of WHM. Hence, WHM can be included up to 20 % in layer diets for optimal meat yield, gut morphology and sensory properties. Key words: Gut morphology, water hyacinth, laying hen |

| Abstract: | This study was conducted to determine the effect of varying aqueous Moringa oleifera leaf extracts (AMOLE) on the gut morphology and pH of Hubbard broiler chickens. A total of 240 Hubbard broiler chickens were randomly allocated into six treatments with four replicates in a completely randomized design. The treatments were positive control (AMOLE ), negative + control (AMOLE), AMOLE (60mL of the extracts per litre), AMOLE (90mL of the extracts 60 90 per litre), AMOLE (120mL of the extracts per litre) and AMOLE (150mL of the extracts 120 150 per litre). Data on gut morphology weight and length and their pH were measured and analyzed by one way analysis of variance. The results showed that dressed, crop, large intestine, kidney and lung weights of birds were influenced (P<0.05) by the treatments. Birds in the control treatments (94.67 %, 94.93 %) had the higher (P<0.05) dressing percentage. Birds on the AMOLE had the higher (P<0.05) crop and large intestine weights (4.47 60 and0.23 %, respectively). The birds on the AMOLE treatment had the largest kidney weight 90 of 0.33 %. Absolute crop and caecum length were influenced by aqueous Moringa oleifera leaf extracts while the relative caecum length was the only relative organ length that was influenced by aqueous Moringa oleifera leaf extracts treatment.The pH of the internal organs showed that the gizzards, duodenum, jejunum, ileum, caecum, kidney and lung were influenced (P<0.05) by the treatments. Birds on positive control treatment had higher pH values in most of the parameters measured. Birds on the AMOLE had the lowest (P<0.05) 120 duodenum, jejunum and lung pH. This study revealed AMOLE had influence on the gut morphology and pH of broiler chickens. Therefore, it can be concluded that the substitution of antibiotics as a growth promoter with aqueous Moringa oleifera leaf extracts up to 120 ml improved the gut morphology and pH of the intestinal segments in broiler chickens. Thus, is recommended that farmers, poultry producers and nutritionists to administer between 60 and 120 mL/litre of AMOLE in the drinking water of broiler chickens to nourish them for good gut morphology and optimum pH of their internal organs. |
