The birds were weighed and randomly allotted to seven treatment groups with three replicates, each having 10 birds. The experimental design was a (2 X 3) + 1 augmented factorial arrangement in a completely randomized design. Diet D1 (control diet) was a maize-soybean meal-based; diets D2, D3, and D4 comprised 10, 20, and 30% DCA without exogenous enzyme supplementation, whereas diets D5, D6, and D7 included 10, 20, and 30% DCA treated with exogenous enzyme. Data were collected on growth performance, total tract digestibility, and gut morphology. Collected data were analyzed using SAS (2002) and separation of means was done using Duncan's Multiple Range Tests of the same statistical software. The difference was set at p < 0.05. The study found that birds fed diets containing 10% DCA, with or without enzyme supplementation (D2 and D5), had a significantly higher Average Daily Gain (ADG) compared to those fed the control diet (D1). The ADG of birds fed diets D3 and D6 was similar to that of birds fed the control diet (D1). However, a significant decrease in ADG was observed as the dietary inclusion level of DCA increased to 30%, as seen in birds offered diets D4 and D7. In addition, a significant linear rise (p < 0.05) in Average Daily Feed Intake (ADFI) was seen when DCA was included in the diet. In addition, birds that were given diets containing DCA showed significantly higher nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1), except for birds that were given a diet containing 30% DCA without enzyme supplementation (D4), which showed significantly lower nutrient digestibility (p < 0.05) compared to birds that were given the control diet (D1). Ultimately, birds that were given meals containing DCA exhibited a significant enhancement in GIT development compared to birds on the control diet. Based on the findings of this study, it can be concluded that including DCA in the diet of broiler chickens at a level of up to 20% does not have any detrimental effects on their performance.

The pigs were grouped into four treatments with eight replicates each. Diet C0 was the basal diet (control). Diets C1, C2, and C3 contained the basal diet with 1g/kg, 2g/kg and 3g/kg of ascorbic acid respectively for seven weeks. The weight of liver, kidney, spleen, heart, and lungs were significantly different (p<0.05) with pigs offered ascorbic acid-supplemented diet having higher values. Also, the villus height, villus width and muscle thickness were significantly influenced (p<0.05) with pigs fed diet C3 having the highest value for villus height and width. The organoleptic properties did not differ significantly (p>0.05). The jejunum villi histology showed that pigs fed diets C0 and C1 were essentially normal while those fed diets C2 and C3 had moderate enteritis. No observable lesions were recorded in the structure of the nephron. Moreover, the hepatic histology of pigs fed diet C1 was essentially normal while those fed diets C2 and C3 showed normal hepatocytes but with moderate sinusoidal congestion. It can be concluded that ascorbic acid supplementation caused increased organ weight, aided villus height and width, and reduced muscle thickness with moderate sinusoidal congestion at up to 3g/kg with no deleterious effects on organoleptic attributes.

Growth performance, economic indices, haematological parameters, serum biochemistry and carcass characteristics were measured. After 49 days, the pigs on diet with ascorbic acid at 2 g.kg-1 had significantly higher daily feed intake (1.54 kg per pig) (p < 0.05). The feed cost per kg increased significantly (p < 0.05) across the diets from the control (Nigerian naira, ₦ 97.60) to basal + ascorbic acid at 3 g.kg-1diet (₦ 103.50). Significantly higher (p < 0.05) red blood cell, haemoglobin, haematocrit and mean corpuscular volume values were recorded in pigs fed ascorbic acid at 2 g.kg-1 diet, while pigs fed ascorbic acid at 3 g.kg-1 diet had the hig...

The feeding trial lasted for 21 days. 180 day-old Marshal strain unsexed broiler chicks were used for this experiment. There were 6 dietary treatments of 30 birds per treatment and 3 replicate of 10 birds each in a complete randomized design. Each differently processed Jatropha curcas kernel meals were used to replace one-third of the soybean meal in the control diet. Data on average daily feed intake (ADFI) of birds fed control (D1) was significantly (P 0.05). Birds fed the D6 diet had the highest total mortality rate (P<0.05) from others except for those fed with the D5 diet which had a similar mortality rate. The result suggests that the processing methods improves the nutrients, however, heat treatments reduced the antinutrients with minimal effect on the saponin and phorbol esters present in the Jatropha curcas kernel meals, which resulted in low feed intake in the diets 2-6. ADFI, ADWG, FGR and total mortality were adversely affected by the dietary treatments as observed by the depressed growth rate and high mortality in birds fed Jatropha curcas meals. However, further experiment should be carried out to examine the performance of broiler chicks on bio-treated samples of the processed Jatropha curcas kernel meals.

A total of 180 day-old Marshal strain unsexed broiler chicks were used for this experiment. There were six dietary treatments of 30 birds per treatment and 3 replicate of 10 birds each in a complete randomized design. Each differently processed Jatropha curcas kernel meals were used to replace one-third of the soybean meal in the control diet. The results suggest that Heat treatment showed superior impact in reduction of atinutritional factors, however, with minimal effect on the saponin and phorbol esters present in the Jatropha curcas kernel meals. Varying levels of villi erosion, loss of mucosal glands and infiltration by inflammatory cells was observed in the small intestine while the nephro-histopathology showed varying levels of necrosis, disruption and degeneration of kidney cells. It can be concluded that broiler chicks cannot tolerate 10.33% inclusion level of differently processed Jatropha curcas kernel meals However, further experiment should be carried out to examine the performance of broiler chicks on bio-treated samples of the processed Jatropha curcas kernel meals.

Castor seeds from four different locations in Nigeria were sampled and investigated for physical and chemical properties. The seeds size ranged from 0.08-0.9 g by weight and 0.8-1.9 cm by height. Since size is a continuous variation, the seeds were categorized into the small seeded variety (SSV) and the large seeded variety (LSY). More time and energy were expended in dehulling the SSV beside a considerable amount of kernel that were lost to the hull during processing. A tonne of castor seed generated about 53% of kernel for LSV compared to 49% kernel in SSV indicating a higher waste stream for SSV. The fibrous seed coat of 25% was obtained in LSV compared to 31% in SSV. The oil content ranged from 35-37% with higher oil yield in SSV. The energy values and the protein content showed numerical differences in the two seed types. Crude protein content of 26.7% and 24.6% and crude fat of 47.3% and 49.4% and gross energy values of 6.59 kcal/g and 6.89kcal/g were obtained for LSV and SSV respectively. The anti nutritional factors measured revealed that the lectin component of 4.7HU mg/ml obtained for LSV and 3.1HUmg/ml obtained for SSV was lower in LSV because more of the material was required to produce positive agglutination. Values of O.41% and 0.48% phytate and 0.94% and 0.79% oxalate were obtained in LSV and SSV respectively. Different processing methods were attempted on the seed meal samples to neutralize the antinutrients present in them. Lectin were better inactivated with extraction with lye water, pH 9.5 and moist heating at 100°C for 20 min. Phytate levels were slightly decreased by fermentation for 3-day. Handling and nutrient profile favoured LSV over SSV and may have higher preference in livestock feeding system when treated with lye.

Jatropha curcas kernels were subjected to five different processing methods, namely: Raw Defatted Fermented Meal (RDFM), Toasted Defatted Fermented Meal (TDFM), Cooked Defatted Fermented Meal (CDFM), Lye treated Defatted Fermented Meal (LDFM) and Sand roasted Defatted Fermented Meal (ZRFM) for a 21 day period in a completely randomized design model. Six (6) dietary treatments were formulated such that Diet 1 contained 0% Jatropha curcas kernel Meal while diets 2, 3, 4, 5 and 6 contained 10.33% (one-third replacement of soybean meal) inclusion level of RDFM, TDFM, CDFM, LDFM and ZDFM. It was observed that Fermentation had little effect on the CP though there was an increase in RDFM, meanwhile the antinutrients increased except for phorbol esters. The improved average daily feed intake, average daily gain and mortality in birds fed...

This study assessed the demographic characteristics of the livestock farmers, type of livestock kept, type of feed used, energy and plant protein feedstuffs used in feed compounding, level of awareness of pigeon pea seed utilization as livestock feedstuff and constraints to the use of pigeon pea seed as livestock feedstuff. The survey results revealed that the respondents were mostly part time livestock farmers, married-middle aged men (?̅?=40 years) with an average 5 years farming experience, who kept majorly poultry and pigs (55-80%) amongst other livestock. Compounded rations (53-83%) were commonly used with maize (66-100%) as the main energy feedstuff while soybean meal (87-90%), groundnut cake (77-100%) and palm kernel cake (8692%) were the major plant protein ingredients. Majority of the respondents (70-82%) were unaware of the po...

These substrates were fed to a total of 120 1-d old broiler chicks at 50 and 100% replacement for soybean. Five experimental diets were formulated with maize-soybean based diet as the control in a Completely Randomized Design in a 42-day feeding trial. Each treatment consisted of 3 replicates, with 8 birds per replicate. The results showed that there were significant (p<0.05) differences among treatments in average daily feed intake (ADFI), average daily gain (ADG) and feed conversion ratio (FCR). The ADFI and ADG were depressed in birds fed 100% FAYB compared with those fed 50% of either of the two legumes while the FCR of those fed 50% of the substrates compared favourably with the control. Birds fed diets containing 100% FPP had higher digestibilities of Ether Extract and ash comp...

The birds were randomly assigned to five (5) experimental diets of four (4) replicates each at ten (10) birds per replicate in a completely randomized design in a forty-two day feeding trial. Diet D1 contained 100% maize; D2 and D3 contained 50% and 100% red sorghum variety (RSV) while D4 and D5 contained 50% and 100% white sorghum variety (WSV) respectively as replacement for maize. The RSV had higher tannin content than WSV. Birds fed WSV based diets had higher (P≤0.05) weight gain with better feed conversion ratio than those fed RSV based diets. The sorghum based diets had a more digestible ether extract and nitrogen free extract (P≤0.05) than those fed D1. Conclusively, WSV could completely replace maize because of the lower (condensed) tannin le...

The chemical composition of PKM showed that it has crude protein (CP) concentration of 14-18% and moderate energy value (10.6 MJ/kg DM) (Kim et al., 2016; Sathitkowitchai et al., 2018). These values are dependent on processing techniques which affect the ether extract and crude fibre content (Ojediran et al., 2020). However, PKM has high levels of non-starch polysaccharides (NSP) such as mannan, xylan which limits its utilisation as feed for non-ruminant animals (Adeola and Cowieson, 2011; Sharmila et al., 2014). The cell wall components of PKM consists of 58% mannan, 12% cellulose and 4% xylan (Sathitkowitchai et al., 2018). Furthermore, PKM is coarse-textured, gritty in appearance and high viscosity which tend to decrease nutrient absorption (Ojediran et al., 2020).

This study assesses the characteristics of the livestock farmers, type of livestock kept, type of feed used, energy feedstuffs used in feed compounding, quantity of feed used daily, level of awareness of cassava peel utilization as livestock feedstuff, factors affecting the utilization of the identified potential energy feedstuff and constraints to the use of cassava peel as livestock feedstuffs. The survey results revealed that the respondents were mostly part time livestock farmers, middle aged men with less than 10 years farming experience, who kept majorly poultry and pigs amongst other livestock such as goat, sheep and mini-livestock. Compounded rations were commonly used with maize as the main energy feedstuff and the quantity of feed used daily indicated that they were small-scale farmers. Majori...

A total of 144 day old broilers (Arbor-acre strain) were used for this study. They were completely randomized and divided into four treatment groups. Each group had three replicates of twelve birds per replicate. Four experimental diets were formulated such that control had maize and treatment 2, 3, and 4 had 5, 10, 15% inclusion of BD respectively at both starter and finisher phases. The responses of the broilers to dietary treatments were measured by feed intake (kg/bird), final weight (kg/bird), feed conversion ratio (FCR), carcass and organ characteristics and nutrients utilization. There were significant differences (p<0.05) across the treatments with treatment 3 and 4 (10 and 15%BD) having the highest values of 104.01 g/bird and 104.63 g/bird daily feed intake and treatment 1(T1) having the least value of 98.17 g/bird/day. For the final live weight, treatments 4, 5 had similar (p>0.05) weight gain (2.55 kg/bird) while treatment 1 had the least (2.25kg/bird). Addition of BD reduced the cost per kg weight gain by approximately 10% at 15% inclusion level. The nutrient digestibility were not significantly affected (p>0.05) across the treatments except the dry matter and nitrogen free extract digestibilities. The carcass weights expressed as a percentages of live weight (LW) were not significantly (p>0.05) affected except neck, wings and thigh. The relative organs weights showed that there were no significant (p>0.05) differences in the liver, gizzard, heart and spleen except kidney weights. It was concluded that biscuit dough can be used to replace 15% maize in broiler diets at both starter and finisher phases without negative effect on performance characteristics of broiler chickens.

Jatropha curcas kernels were subjected to five different processing methods, namely: Raw Defatted Fermented Meal (RDFM), Toasted Defatted Fermented Meal (TDFM), Cooked Defatted Fermented Meal (CDFM), Lye treated Defatted Fermented Meal (LDFM) and Sand roasted Defatted Fermented Meal (ZRFM) for a 21 day period in a completely randomized design model. Six (6) dietary treatments were formulated such that Diet 1 contained 0% Jatropha curcas kernel Meal while diets 2, 3, 4, 5 and 6 contained 10.33% (one-third replacement of soybean meal) inclusion level of RDFM, TDFM, CDFM, LDFM and ZDFM. It was observed that Fermentation had little effect on the CP though there was an increase in RDFM, meanwhile the antinutrients increased except for phorbol esters. The improved average daily feed intake, average daily gain and mortality in birds fed the dietary treatments could be attributed to the reduced phorbol esters during fermentation while the varying levels of hepatic degeneration can be attributed to the residual antinutrients in the meals. It can be concluded that the birds cannot tolerate the 10.33% inclusion level.

level of Jatropha seed cake (JSC) fermented for different number of days in broiler
starter diets on the production performance in order to recycle this by-product and
prevent pollution. Diet 1 (Control diet) contained no JSC. Diets 2, 3, and 4
contained 4% JSC fermented for 7, 11 and 15 days respectively while diets 5, 6
and 7 contained 6% JSC fermented also for 7, 11 and 15 days respectively. The
diets were fed to seven groups of forty birds each in a completely randomized
design with four replicates per treatment. Data were collected on production
performance, nutrient utilization, carcass characteristics, blood profile and
production economy. Data collected were analyzed by ANOVA. The results
revealed that birds that received JSC containing diets had lower (P<0.05) weight
gain, live weight, dressed weight, carcass yield and nutrient digestibility than the
control irrespective of the level and length of fermentation. Feed cost decreased
with increase level of JSC in the diets while production cost was higher in birds
that received JSC. Feed conversion by the birds that received JSC was poor
compared to that of the control while feed intakes, mortality, gizzard weight, blood
components except ALT were unaffected. Birds that received diets that contained
JSC had smaller (P<0.05) liver and pancreas but higher ALT value than the control.
It was concluded that broilers cannot tolerate 4% nor 6% JSC fermented for 15
days or less.

Differently processed bean meals namely dehulling (DUMM), dehulling and cooked (DCMM), soaked and cooked (SCMMI) prolonged soaking and cooking (SCMMII) and toasting (TMM) mucuna meals were fed to two hundred and seventy 1 – day old broiler chicks of Anak strain. The birds were divided into six groups of 45 birds per group. Each group was further sub divided to 3 replicates of 15 birds and allocated to six dietary treatments in a completely randomized design. Maize – soybean meal served as control diet. Processed mucuna meal was added to the diet 200g/kg of feed at the expense of soybean meal in the control diet. All diets formulated were isocaloric and iso-nitrogenous. Feed intake was not influenced by the dietary treatments (P>0.05). Average daily gain (ADG) was significantly (P<0.05) influenced by the dietary treatments. Growth was depressed in birds fed dehulled mucuna meal compared to other dietary treatments. Compared with DUMM, there was significant improvement in ADG in bird fed heat treated mucuna meal. Feed conversion efficiency was significantly improved (P<0.05) in birds fed aqueous heated meals (DCMM, SCMMI and SCMMII) compared with those that received DUMM and TMM diets. Dietary treatments significantly (P<0.05) affect blood cellular components. The PCV, Hb, and RBC of broilers chickens fed DUMM were reduced with increased MCV and MCH values compared to other treatments. Serum total protein and globulin were affected by the dietary treatments (P<0.05). Values obtained in birds fed SCMMI, SCMMII, DCMM and TMM were similar and significantly lower than those that received the control and DUMM diets. The result of this study revealed that aqueous heat treatment (cooking) was more effective in improving the nutritive values of mucuna bean meals compared to dehulling and toasting.

characteristics and economic indices of broilers fed low protein diets fortified with synthetic lysine.
Study Design: All data generated were subjected to analysis of variance in a complete randomized
design.
Place and Duration: The experiment was carried out at the Teaching and Research Farm of the
Ladoke Akintola University of Technology, Ogbomoso, Nigeria, between November and December
2014.
Methodology: One hundred and eighty unsexed Abor Acres strain day old broiler chicks were used
in a seven-week feeding trial. Five experimental diets were formulated. Diets 1 and 2 were negative
and positive control respectively with 22.23% crude protein while diets 3, 4 and 5 contained 18.2%
each at the starter phase and 17.8% at the finisher phase. They all had recommended level of
methionine with varying levels of synthetic lysine inclusion ranging from 0.40% in diet 1 to 0.65% in
diet 5 at the starter phase and 0.40 to 0.60% at the finisher phase.
Results: The result indicated that birds on diet 3 with 18.26% crude protein (CP) and high lysine
inclusion had a higher (P<0.05) daily gain and least feed to gain ratio at the starter phase, although,
the birds on low protein diets had a numerical increase in feed intake but weight gain decreased as
the lysine inclusion increased beyond diet 3. The fortification with lysine resulted in a least cost input
but an increased profit, economic efficiency of growth, live weight and thigh.
Conclusion: From this study, the objective of the poultry farmer to achieve optimum production with
least input is possible using a low crude protein diet supplemented with lysine. This will result in
increased profit, economic efficiency of growth, live weight and thigh size.
