Due to scarcity and high cost of conventional feedstuffs, there is a renewed interest in the use of non-conventional cheap and easily available feedstuffs on ducks feeding. This study was conducted to evaluate health status of ducks fed fermented cassava root-leaf meal blend as a replacement for maize. One hundred and fifty, one day- old unsexed Mallard ducklings were used for the experiment. Ducklings were randomly distributed into 5 groups of 30 ducklings per treatment. Each treatment was further subdivided into 3 replicates with 10 ducklings per replicate in a completely randomized design (CRD). The study is made up of 5 dietary treatments consisting of the control (Treatment 1), fermented cassava root-leaf blend used to replace maize at 25% (Treatment 2), 50% (Treatment 3), 75% (Treatment 4) and 100% (Treatment 5) levels respectively. The packed cell volume (26.50-38.33%) and haemoglobin (9.35-14.07g/dl) levels increased as Fermented cassava root-leaf meal (FCRLM) inclusion increased in the diet (0-75%). Uric acid values decreased (5.30-4,27mg/dl) as well as cholesterol values (91.70-56.70mg/dl) as level of (FCRLM) increased in diet. The results obtained showed that FCRLM at (300:1000 ratio) of leaf to root could replace maize at 50% inclusion level without any detrimental effects on health status of ducks.

Aim: This study is to evaluate the effects of using bread waste fortified with moringa leaf meal on broiler chickens. Methodology: Bread wastes were sun-dried and moringa leaves air-dried. The two dried products were milled separately. Thereafter, the meals were mixed in ratio 9:1 (9 kg Bread Waste + 1 kg Moringa Leaf) to produced fortified bread wastes. Four broiler starter diets and four finisher diets were formulated using fortified bread waste at graded levels of 0, 5, 10 and 15% and designated diets I, II, III and IV, respectively. Two hundred chicks were assigned to four dietary treatments of five replicates and ten chicks per replicate in a Completely Randomized Design. Diets and water were fed to the broilers ad libitum from 0 - 28 days as starter phase and 29 - 56 days as finisher phase. Results: Highest final weight gain and total weight gain (2.12 kg/bird and 2.07 kg/bird) and least feed conversion ratio (2.32) were observed in bird fed Diet I. The dressed weight, eviscerated weight, head, chest, drumstick, wing, thigh, back and shank were influenced significantly (P˂0.05) by the dietary treatments. Highest dressed weight (92.64%), eviscerated weight (79.52%), head (25.34 g/kg body weight), chest (206.53 g/kg body weight) and wing (83.10g/kg body weight) were recorded in bird fed Diet I. Only lymphocyte was influenced (P < .05) by the dietary treatments. Erythrocyte sedimentation rate varies: 2.33 - 3.33 mm/hour, packed cell volume: 26.67 - 28.67%, haemoglobin concentration: 9.23 - 9.88 g/100 ml and mean cell haemoglobin concentration: 34.41 - 34.61%. Cholesterol and alkaline phosphatase were influenced (P < 0.05) by the dietary treatments. The cholesterol: 22.57 - 32.78 mg/dl and alkaline phosphatase: 144.17-150.98 IU/I. Conclusion: From the results obtained in this study, it can be concluded that increasing levels of fortified bread wastes in broiler chicken diets up till 5% inclusion level can be practiced.

Abstract Background Twenty-four West African Dwarf (WAD) goats with average weight of 6.57 ± 0.56 kg were used in investigating the effect of microbial-treated maize cob and husk diets on blood profile. The goats were assigned to six dietary treatments replicated four times in a completely randomized design. Chopped maize cobs and husks were sterilized for 60 min to eliminate any form of contamination and then inoculated with mixture of 15 ml each of Lactobacillus delbrueckii and Neurospora crassa and incubated anaerobically for 5 days and then air-dried. The treated maize cob and husk were incorporated in the diets at the rate of 0% (diet), 20% (diet B), 30% (diet C) [maize cob diets], and 0% (diet D), 20% (diet E), 30% (diet F) [maize husk diets], respectively. The animals were acclimatized for two weeks while the experimental period lasted for 56 days. A completely randomized design was adopted. Results The results showed that the dietary treatments significantly (P < 0.05) influenced the erythrocyte sedimentation rate which ranged from 0.50 to 1.00 mm/hr. Significant (P < 0.05) differences were observed in the globulin (28.16 g/dl diet A—59.26 g/dl diet B), aspartate aminotransferase (48.00 u/l diet E—128. 25 u/l diet C) and alanine aminotransferase (8.20 u/l diet A—33.33 u/l diet D). Serum electrolytes values were significantly (P < 0.05) influenced by dietary treatments. Conclusion Based on the findings of this study, microbial-treated maize cob and husk diets supported erythropoiesis did not induce any liver damage and the serum electrolytes of the animals were improved. Hence, microbial-treated maize cob and husk can be a suitable alternative feed source at 30% incorporation in a complete diet for WAD goats as adverse implications on the health of the animals was not observed.

This study was carried out to investigate the effect of equi-protein replacement of soybean meal with groundnut cake on immune status, haematology and serum biochemical parameters of broiler chickens. A total of One hundred and twenty (120) Cobb’s day old chicks were randomly allocated to five (5) dietary treatments of three (3) replicates and eight (8) chicks per replicate in a completely randomized design. The Diet I was the control diet with 100% SBM as the major plant protein source while in other diets, SBM was replaced with 25, 50, 75 and 100% GNC in equi-protein basis and designated as Diets II, III, IV and V respectively. Feed and water were provided ad-libitum throughout the experimental period of 56 days. Newcastle disease (ND) vaccines were administered following a stipulated regime. At the end of the experiment two birds were randomly selected from each replicate and slaughtered. Blood and serum was collected for haematological analysis, serum bioassay and HA/HI tests to determine antibody titres against ND vaccines. All data collected were subjected to one-way analysis of variance using SPSS software package. Results showed that haematological parameters were significantly influenced by the dietary treatments in which birds fed 50% equi-protein replacement of SBM with GNC had better PCV, basophil, MCH and MCHC values compared to that of birds in the other dietary treatments. The antibody titres of experimental birds were not significantly different among treatment groups. The diet with 50% equi-protein replacement of SBM with GNC elicited the highest antibody titres of Log28 and Log210 after the 1st and 2nd ND vaccinations when compared to the other diets. The serum total protein, globulin, albumin, and glucose were significantly influenced by the dietary treatments. The present result indicate that 50% equi-protein replacement of SBM with GNC in diets is not detrimental to health status of broiler chickens.

The quest for sustainable poultry production using alternative feed ingredients is imperative. This study was conducted to assess the growth performance and blood profile of broiler chickens fed neem leaf meal (NLM) based diets with or without enzyme supplementation. Two hundred and eighty-eight, one-week old chicks (with an average weight of 98.44g) arranged in a completely randomized design with twelve birds/ replicate and three replicates/ treatment were fed NLM at 0, 1.5, 3 and 5% with or without Polyzme® to form eight experimental treatments. Data on initial body weights, weekly body weights and feed intake were taken during the trial which lasted for eight weeks and feed conversion ratio calculated. Blood was also collected for haematological studies at the 4 and 8 week by humanely severing the jugular vein. Results indicated that total weight gain at starter phase decreased progressively with increase in NLM inclusion and addition of Polyzme did not significantly (P>0.05) affect performance. At the finisher phase, growth performance was not significantly (P>0.05) influenced by NLM or enzyme addition. Furthermore, NLM with/without Polyzyme did not elicit any significant influence on the packed cell volume and haemoglobin concentration of the chickens. In conclusion, broiler chicks could tolerate up to 3% NLM and finishers up to 5% based on growth performance. The use of polyzyme at 400g/tonne in this study did not improve the utilization of NLM by the chickens.    La recherche de la production de volaille durable utilisant des ingrédients d'alimentation alternatifs est impérative. Cette étude a été réalisée pour évaluer la performance de la croissance et le profil sanguin des régimes à base de feuilles neem (NLM) avec ou sans supplémentation en enzyme. Deux cent quatre-vingt-huit poussins âgés d'une semaine (avec un poids moyen de 98,44 g) disposés dans un design complètement randomisé avec douze oiseaux / répliqués et trois répliqués / traitement ont été nourris à 0, 1,5, 3 et 5% avec ou sans Polyzme pour former huit traitements expérimentaux. Les données sur les poids corporels initiaux, les poids corporels hebdomadaires et l'apport alimentaire ont été pris au cours de l'essai qui a duré huit semaines et le ratio de conversion alimentaire calculé. Le sang a également été collecté pour des études hématologiques à la 4ème et 8ème semaine en coupant humainement la veine jugulaire. Les résultats ont indiqué que le gain de poids total à la phase de démarrage a diminué progressivement avec l'augmentation de l'inclusion de NLM et l'addition de polyzme n'a pas significativement (p> 0,05) affecter les performances. À la phase de finition, la performance de la croissance n'était pas significativement (p> 0,05) influencée par l'addition NLM ou enzyme. De plus, la NLM avec / sans polyzyme n'a suscité aucune influence significative sur le volume de la cellule emballé et la concentration en hémoglobine des poulets. En conclusion, les poussins de chair pourraient tolérer jusqu'à 3% de NLM et des finisseurs jusqu'à 5% sur la base de la performance de la croissance. L'utilisation de polyzyme à 400 g / tonne dans cette étude n'a pas amélioré l'utilisation de NLM par les poulets.

The effect of raw jackfruit (Artocarpus heterophyllus) seed meal (JFM) on performance, nutrient utilization and economics of production was investigated using 144 broiler chickens.The birds were divided into four dietary treatments of 3 replicates and 12 birds per replicate in a completely randomized design. Diet one was soybean based (control) while raw JFM meal was added to diets 2 (T ), 3 (T ) and 4 (T ) at 10, 20 and 30% levels of inclusion 2 3 4 of soybean meal in the control diet respectively. At 8 weeks, 2 birds per replicate were used to evaluate nutrient utilization. The growth performance was generally depressed with increased inclusion of raw JFM in the diets. The feed to gain ratio of birds placed on control diet (2.55) and T (2.56) were the same (P>0.05) and are significantly better (P < 0.05) than 2 other treatments. Nitrogen, ether extract and ash retention were virtually the same for birds fed T T and T while energy retention was higher (P<0.05) in birds fed T (2,82MJ/Kg ME) 1, 2 3 1 than those fed T , T and T .The cost per Kg feed was higher in T (? 131.59) and decreased 2 3 4 1 with increase in inclusion of raw JFM; T (? 127.17), T (? 123.66) and T (? 123.24). Cost per 2 3 4 Kg weight gain, revenue and gross margin were the same for birds fed control and those fed with T . From the foregoing raw JFM is a potential feed resource and could be included in the 2 diet of broiler chicken up to 10% level of inclusion of soybean meal in a control diet.

The blood profile and histology of selected tissues (kidney, lungs, intestine, and epididymis) of Balami Sheep fed Shea Cake meal supplement was investigated. A total of thirty-two (32) sheep of the average weight range of 11.75-14.75kg comprising an equal number (16) of males and females were randomly allotted to four dietary treatments in a completely randomized experimental design with eight sheep per treatment for twelve weeks duration. Treatment 1 (T1) was a control diet and had zero inclusion level of Shea cake meal (SCM), while treatments 2,3, and 4 had 10%,15%, and 20%  inclusion of SCM, respectively. At the twelfth week of the experiment, two blood samples of 5ml each were taken from each animal from the jugular vein. The first set was preserved in Ethylene Diamine Tetra Acetic Acid (EDTA) bottle for haematological parameters, while the second samples were preserved without EDTA for serum examination. Representative samples of tissues were randomly selected and slaughtered for gross microscopic examination. There was a significant difference (P<0.05) at various levels of inclusion for parameters investigated. The white blood cell (WBC), Red blood cell (RBC), and Packed cell volume (PCV) recorded the highest values at T3 (15% inclusion level) (13.42 x109/L), 2.92x1012/L, 3.75%, respectively). The serum parameters were significantly(p <0.05)different among the treatments. Total protein ranges from 54.78(mg/dl) (T1) - 60.51(mg/dl) (T2), Cholesterol70.15(mg/dl) (T1) - 78.00(mg/dl) (T4). Iron ranges from 58.15(ug/dl) (T1) - 62.88(ug/dl) (T3).The histopathology of tissues (kidney, lungs, intestine, and epididymis) showed no alteration across the treatments (P= .05) in the gross microscopic examinations. No lesion was observed in the lungs, kidney, epididymis, and intestine. The results showed that shea cake meal posed no health risk to Balami sheep and as such recommended as a good supplement in the diets of the sheep.

Enzyme supplementation in diets based on corn and soybean meal can improve the productive performance of broilers. Thus, we aimed to evaluate the effect of the inclusion of different levels of an enzyme complex consisting of phytase, protease, xylanase, ?-glucanase, cellulase, amylase, and pectinase, for diets based on corn and soybean meal, on the parameters of carcass yield and meat quality of broilers. Six hundred broiler chicks were used, and the animals were females with one day of age, from the Cobb 500 strain, and distributed in a completely randomized design, with five levels of inclusion of the enzyme complex (0, 100, 200, 300 and 400), and six repetitions, with twenty animals each. The carcass yield and meat quality were evaluated at 35 and 42 days of age. We evaluated the characteristics of weight loss by cooking (WLC), shear force (SF), water holding capacity (WHC), pH, lightness (L*) and color (a* and b*). The parameters of performance, carcass yield and carcass parts, and meat quality were not affected by the enzyme supplementation of diets fed to broiler chickens (P >0.05), except for the performance characteristics of the breast and the wings at 42 days of age (P < 0.05).
