ANTINUTRITIONAL FACTORS INTAKE IN LAYING HENS FED COCOYAM (Xanthosoma sagittifolium) BASED DIET
ANTINUTRITIONAL FACTORS INTAKE IN LAYING HENS FED COCOYAM (Xanthosoma sagittifolium) BASED DIET
The study was conducted to evaluate the effect of cocoyam-based diets processed by either boiling or sun
drying on anti-nutrient intake of laying hens. A total of 160 day old commercial chicks (Shika Brown)
were allotted to seven dietary treatments (n=20 birds per treatment) in a 2×3+1; 2 factorial arrangement: 2
factors (raw and boiled cocoyam), 3 levels (25, 50 and 75%) and 1 control (0%; n=40) in a completely
randomized design, with 80 chicks for raw sun dried (RS) cocoyam and 80 chicks for boiled sun dried
(BS) cocoyam. The cocoyam inclusion rates comprised 4 diets from RS and 4 from BS cocoyam, each
replacing maize at 0, 25, 50, and 75%. During the 12-months experimental period, the birds were given
feed based on their nutritional requirements and water ad libitum, routine vaccinations and medications
were administered appropriately. Data collected on anti nutritional factors (oxalate, phytate, tannin,
saponin, cyanide and hydrogen cyanide) were subjected to analysis of variance and significant differences
among treatment means were compared using pair wise difference method (P diff test) at 5% level of
significance. The results indicated a significant (P<0.05) reduction in intake of the antinutritional
components in the BS diets compared to the RS diets. The inclusion levels showed significant (P < 0.05)
differences across all parameters. It was concluded that processing cocoyam by boiling resulted in lower
antinutritional factor intake, with the 50% inclusion level having the lowest values and thus
recommended.
Growth Performance, Carcass traits, and Economic Implications of Replacing Soybean Meal with Moringa Leaf Meal in Japanese Quail Diets
Growth Performance, Carcass traits, and Economic Implications of Replacing Soybean Meal with Moringa Leaf Meal in Japanese Quail Diets
This study evaluated the effects of partially or completely replacing soybean meal (SBM) with
moringa leaf meal (MOLM) on growth performance, carcass characteristics, and feed cost in Japanese
quail. A total of 60 unsexed quails with initial body weight of 22.7 g were randomly assigned to five
diets: T1 (20% SBM, 0% MOLM), T2 (15% SBM, 5% MOLM), T3 (10% SBM, 10% MOLM), T4
(5% SBM, 15% MOLM), and T5 (0% SBM, 20% MOLM) with 12 quails per treatment, replicated
four times in a Completely Randomized Design and study lasted for four weeks. The parameters
evaluated included growth performance, carcass yield and organ weights, and cost analysis. The
results showed that growth performance decreased significantly (P<0.05) with increasing MOLM
inclusion, particularly at 15–20%. Birds fed 5% MOLM had comparable performance to control,
whereas ≥10% inclusion depressed growth. Feed cost/kg declined as MOLM increased, but feed
conversion ratio (FCR) and cost per unit weight gain worsened. Carcass traits followed similar trends,
with lower dressing weight and breast yield at higher MOLM levels. The study therefore concluded
that MOLM can partially replace SBM in quail diets at up to 5% without adverse effects on
performance and profitability, while higher levels compromise growth efficiency despite lowering
feed cost.
