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.

This study evaluated the effect of phytogenic feed additives (Lemon peel, LP and Orange peel, OP) added singly or in combination to basal diets on the performance, gut morphology, haematology, serum biochemistry and lipid profile of broiler chickens. Four nutritionally adequate Corn-Soybean based diets were generated by the addition of LPand/or OPto basal diet. A total of 320, 1-d-old Marshall strain broiler chicks were given the basal diet supplemented with no additive (T1), 500g/tonne of LP (T2), OP (T3), or LP+OP (T4) in a study which lasted for 42 days. Growth performance was assessed weekly while gut and blood samples were collected at d 42 for examination. Data generated were analyzed using ANOVA with a P<0.05 level of significance. Results showed that chickens fed diets supplemented with LP and OP had similar (P>0.05) growth performance compared with the control group. Higher (P<0.05) duodenal and jejunal villus height were observed in chickens fed LP and OP, respectively. Phytogenics inclusion caused reduced (P<0.05) laminal propria depth at the ileum segment. Higher (P<0.05) PCV (30.00%), total protein (6.89 g/L) and albumin (3.67 g/L) were observed in chickens on LP+OP. Haemoglobin concentration (Hb) and RBC were not affected by the treatments imposed. Serum creatinine, uric acid and liver enzymes (AST and ALT) activity were reduced (P<0.05) with inclusion of LP and OP in broiler diets. Increase (P<0.05) HDL and decrease total cholesterol, LDL and triglycerides were observed in broilers fed LP and OP. Dietary inclusion of LP and OP had positive influence on gut morphology, RBC production, plasma protein reserves and lipid profile of broiler chickens.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Intestinal Lesion

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

Abstract An experiment was conducted on 240 one-day old male (Ross308) chicken to the effect of substitution of dried mealworm (Tenebrio molitor) with soybean meal on growth performance and carcass characteristics broiler chicks. Chicks fed in a completely randomized design with 4 replicate cages (12 birds per cage). Five dietary treatments used: 1- Control treatment: Basal diet based on corn-soybean meal without adding dried mealworm, 2- Replacement of 5% dried mealworm with soybean meal in the base diet, 3- Replacement of 10% dried mealworm with soybean meal in the base diet, 4- Replacement of 15% dried mealworm with soybean meal in the base diet and 5- Replacement of 20% dried mealworm with soybean meal in the base diet. The results of the experiment showed that 3rd and 4th treatments with a substitution of 10 and 15 percent showed a higher mean weight gain and a daily gain, but their feed intake was lower comparing other treatments, and finally, the feed conversion ratio showed a significant decrease with respect to control treatment using these replacement levels. At 21 and 42 days of age, carcass yield and relative weight of the breasts showed significant increases in treatments 3 and 4, and other characteristics of chicken carcasses were not affected by the test treatments. The experiment showed that replacing soybean meal with 10% and 15% worm powder significantly improved the performance of broiler chickens, but no significant difference was found between the two levels.

Heat stress (HS) is an environmental stressor challenging poultry production and requires a strategy to cope with it. A total of 288-day-old male broiler chicks were fed with one of the following diets: basal diet, basal with betaine (BET), or with selenium and vitamin E (AOX), or with a combination of BET and AOX, under thermoneutral and cyclic HS. Results showed that HS reduced average daily feed intake (ADFI) (p = 0.01) and average daily gain (ADG) (p < 0.001), and impaired feed conversion ratio (FCR) (p = 0.03) during rearing period (0–42 day). BET increased ADG (p = 0.001) and decreased FCR (p = 0.02), whereas AOX had no effects. Breast muscle weight was decreased by HS (p < 0.001) and increased by BET (p < 0.001). Rectal temperature was increased by HS (p < 0.001) and improved by BET overall. Respiration rate was increased by HS (p < 0.001), but BET decreased it during HS (p = 0.04). Jejunum transepithelial resistance was reduced by HS and had no effect on permeability whereas BET increased jejunum permeability (p = 0.013). Overall, the reductions in ADG of broiler chickens during HS were ameliorated by supplementation with BET, with much of the increase in ADG being breast muscle.

A total of two-hundred-and-forty day old broiler chicks were used to study the response of broiler birds to diets containing graded levels of tiger nut residue (TNR) as a replacement for maize. The diets consisted of 0, 10, 20 and 30% of TNR as a replacement for maize as T1 (control), T2, T3 and T4 respectively. The birds were allotted to four dietary treatments of 4 replicates each containing 60 and 15 birds respectively in a completely randomized design. The data obtained from the experiment were subjected to one - way analysis of variance. The results showed that average weight gain (AWG) and final weight gain (FWG) were high for birds fed 10% TNR and increased numerically than the 0, 20 and 30% groups at the starter phase. In the finisher phase the average weight gain (AWG) and final weight gain (FWG) followed the same trend. Feed intake was not significantly affected by the diet at the starter and finisher phases. In the starter phase the T1 (control) recorded the best and the lowest feed conversion ratio but in the finisher phase, the best feed conversion ratio was observed in T2. The TNR inclusion had no significant (p˃0.05) effect on live weight, dressed weight, dressing percentage, cut-parts and organs of the birds. The haematological parameters were not significantly (p˃0.05) affected by the diets. All the biochemical parameters determined; serum protein, albumin, globulin, urea, creatinine, ALT, AST, cholesterol and triglyceride were not significantly (p˃0.05) affected by the treatment diet. It was concluded that tiger nut residue (TNR) as a replacement for maize at a 30% level of inclusion did not cause any deleterious effects on the performance, carcass and blood profiles of broilers

The study investigated the effects of kaempferol on growth performance in two weeks old broilers challenged with Eimeria tenella. Sixty, one-day old broiler chicks were randomly allotted into six groups (I-VI) of ten broiler chicks each and brooded for two weeks with commercial broiler feed (vital feed®) and provided water ad libitum. At two weeks of age, broilers in group 1 were neither infected nor treated. Broilers in groups II- VI were infected 4 with Eimeria tenella sporulated oocyst (10 /mL) via oral inoculation. After infection was established, broilers in groups II-IVwere treated Per os with 1 mg/kg, 1.5 mg/kg and 2 mg/kg of kaempferol respectively. Broilers in group V were treated for five days with amprolium, 1.25 g/L in drinking water and those in group VI were administered normal saline, 5 mL/kg per os for five days. The experimental birds were examined daily for feed intake (FI), weight gain (WG) and feed conversion ratio (FCR). Data obtained were analyzed using pad prism version 5.0. There was a statistically significant (p<00.5) increase in the mean values of WG, FI and FCR in groups II, III and IV in a dose dependent fashion when compared to VI. There was also statistically significant (p<00.5) reduction in the mean values of WG in Group II and III than in Groups IV and V. Mean WG of Groups IV and V did not differ statistically, but there were statistically higher WG in Group V than in group IV. There were consequent high FCR values of 7.3, 5.71, 5.67, 6.19 and 7.08 for groups I, II, III, IV and V respectively compared to 4.9 for Group VI. Thus, the treatment with kaempferol in two weeks old broilers had ameliorated the effects of Eimeria tenella on WG, FI and FCR in this study.

This study compares between different selenium forms (sodium selenite; SeS, selenomethionine; Met-Se or nano-Se) and levels on growth performance, Se retention, antioxidative potential of fresh and frozen meat, and genes related to oxidative stress in Ross broilers. Birds (n = 450) were randomly divided into nine experimental groups with five replicates in each and were fed diets supplemented with 0.3, 0.45, and 0.6 mg Se/kg as (SeS, Met-Se), or nano-Se. For overall growth performance, dietary inclusion of Met-Se or nano-Se significantly increased (p < 0.05) body weight gain and improved the feed conversion ratio of Ross broiler chicks at the level of 0.45 and 0.6 mg/kg when compared with the group fed the same level of SeS. Se sources and levels significantly affected (p < 0.05) its concentrations in breast muscle, liver, and serum. Moreover, Se retention in muscle was higher (p < 0.05) after feeding of broiler chicks on a diet supplemented with Met-Se or nano-Se compared to the SeS group, especially at 0.6 mg/kg. Additionally, higher dietary levels from Met-Se or nano-Se significantly reduced oxidative changes in breast and thigh meat in the fresh state and after a four-week storage period and increased muscular pH after 24 h of slaughter. Also, broiler’s meat in the Met-Se and nano-Se groups showed cooking loss and lower drip compared to the SeS group (p < 0.05). In the liver, the mRNA expression levels of glutathione peroxidase, superoxide dismutase, and catalase were elevated by increasing dietary Se levels from Met-Se and nano-Se groups up to 0.6 mg/kg when compared with SeS. Therefore, dietary supplementation with 0.6 mg/kg Met-Se and nano-Se improved growth performance and were more efficiently retained than with SeS. Both sources of selenium (Met-Se and nano-Se) downregulated the oxidation processes of meat during the first four weeks of frozen storage, especially in thigh meat, compared with an inorganic source. Finally, dietary supplementation of Met-Se and nano-Se produced acceptable Se levels in chicken meat offered for consumers.

Two thousand four hundred male broiler chicks were used in three experiments to evaluate the biological and economic effects of using arsanilic acid as a growth promoter. In two experiments four treatments were (A) control diets (CD); (B) CD plus 99 mg kg−1 arsanilic acid; (C) CD plus drinking water containing arsanilic acid calculated to achieve equivalent exposure to treatment B; and (D) same as treatment C except arsanilic acid concentration reduced by 50%. A third experiment evaluated the dietary addition of arsanilic acid at 0, 33, 66 and 99 mg kg−1. Arsanilic acid supplementation had no significant (P > 0.05) effect on mortality, feed conversion, final live body weights or monetary returns at slaughter age (42 d). Analysis of breast, thigh and liver tissues using method with a sensitivity of 0.02 mg kg−1 showed a significant increase in liver arsenic residues when supplemented diets were fed to slaughter age. Withdrawal of arsanilic acid from diets 7 d prior to slaughter returned the arsenic residues to normal background (control) levels. It is concluded that the use of arsanilic acid at dietary concentrations up to 99 mg kg−1 (the maximum permissible in Canada) was ineffective in improving either the biological or economic performance of broiler chickens. Key words: Arsanilic acid, growth promoter, broiler chickens
