Background: Recently, the use of antibiotic growth promoters has been banned in many countries due to cross-resistance among pathogens and residues in tissues, which led to search for the alternative feed additives in animal production. The aim of this study was to investigate the effects of “Kalo jeera” (Nigella sativa) powder and amino acids supplementation on the growth of broiler chicks and their blood parameters. Methods: A total of 100 day-old (Cobb® 500) chicks were randomly divided into four groups such as T0, T1, T2, T3, and each group contained 25 chicks. The group T0 was used as control and groups T1, T2 and T3 were treated group. Chicks of control group were fed with only basal diet and no supplements were supplied, and chicks of treatment group including T1, T2 and T3 were supplemented with amino acids, Nigella sativa powder and combination of Nigella sativa and amino acids, respectively. Body weight was recorded on 7th, 14th, 21th, 28th and 35th day of age. Haematological tests were performed at 15th, 25th and 35th day of age. Results: The results showed that net weight gain and feed conversion ratio were improved in the treated groups than that of the control group. Among the treated groups, the significant level of improvement was achieved in the T3 group followed by T1 and then T2. Total erythrocyte count, packed cell volume and haemoglobin concentration were significant (p<0.01) in the treated groups as compared to control. Conclusions: The results suggest that better growth performance could be achieved in broilers supplemented with Nigella sativa and amino acids in combination and those can be used as growth promoters.

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.

Experimental Trials

Introduction: Various types of feed additives have been evaluated under commercial conditions and in experimental trials with the aim to achieve improvements on growth performance and the best economic return. Herbs, including Sesame indicum leaves, spices and various plant extracts/essential oils can be used as alternatives to replace antibiotic growth promoters as they are rich in phytochemicals (active compounds) that can be used to stimulate growth and health of the animals. The uses of all these herbs should be studied in relation to the blood and serum indices of the animals in order to determine their harmful level of consuming them by the animals. Therefore, the aim of the study is to determine the effect of different dietary inclusion levels of Sesame indicum leaves on haematology and serum parameters of broiler chickens at both starter and finisher phases. Methods: A total of one hundred and fifty 1-day old, unsexed (Marshal) broiler chicks were randomly divided into five experimental groups at rate of 30 birds per group. Each group was further subdivided into three replicates at the rate of ten chicks per replicate in a Complete Randomized Design. A maize-soybean basal diet served as control while the Sesame indicum leaves was added to the basal diets at level (0g, 10g, 20g, 30g and 40g/kg) resulting in five formulae, respectively. At the end of the 4th and 8th weeks respectively, six birds were randomly selected from each of the replicate and blood samples were collected from the jugular vein of birds for haematology and serum. Results: The results indicated that all the haematology and serum parameters were significantly (p < 0.05) affected by the different inclusion levels of S. indicum leaves but the value obtained were within the recommended range while birds fed with the diet containing 40g/kg of S. indicum leaves had the highest values. Conclusion: Inclusion of S. indicum leaves in the diets appear not to have detrimental effect on the haematology and serum parameters of the experimental birds. The study recommended that 40g/kg inclusion level be adopted as it improved growth performance and general well-being of broiler chickens.

Effects of different available commercial probiotics on growth performance and blood parameters were evaluated. To achieve the objectives, a total of 198 one-day-old Hubbard Isa Starbro broiler chicks were raised over 28 days. Chicks were wing-banded, weighed individually and randomly allocated into six equally major groups each having three replicates. Broilers of group T1 (control group) were fed the starter and finisher diets. The broilers of groups T2 was fed the control starter and finisher diets supplemented with antibiotic and groups T3-T5 were fed 4 different commercially available probiotics (T3-Guardizen-M, T4-Protexin and T5-Poultry star sol in drinking water. Weekly body weight, feed consumption and feed conversion were recorded during experimental period. Blood parameters at 4 weeks of age including packed cell volume (PCV), haemoglobin (Hb), total protein, albumin, triglycerides, high density lipoprotein (HDL), uric acid, cholesterol, glucose, intestinal microflora, pH and color properties of meat were determined. All birds were kept under similar environmental, managerial and hygienic conditions. Probiotic supplementation significantly increased the body weight and daily weight gain of broiler chicks at 28 days (p<0.05). Improved feed conversion was noticed in birds fed a diet supplemented with probiotic. The effects of probiotics on carcass and some internal organs were measured and results shows that feeding broilers with probiotics have significant effects (P < 0.05) on dressed carcass weight, abdominal fat, breast, thigh and liver while it appeared insignificant on gizzard (P> 0.05). The lower percent of abdominal fat and the higher percent of dressed carcass, breast and thigh were observed in experimental probiotic(s) groups. pH and meat color did not affect among treatments. There was lower mortality rate in probiotics among groups. Moreover, there was no significant change for Hb, PCV, total protein and albumin concentrations among different groups. Also, total protein, lipids and albumin concentrations were not affected by probiotic(s) supplementation. In addition, different probiotics showed a significant decrease (p<0.05) in triglycerides, cholesterol and uric acid concentration compared to control group. Birds supplemented with probiotics had higher number of lactobacilli but lower number of colibacilli compared to the control. It can be concluded that use of selected commercial probiotic(s) resulted in improved growth performance and carcass yields, and reduced serum cholesterol and uric acid in broiler chickens. Moreover, supplementation of the probiotic(s) to broilers had no detrimental effect on their growth performance and blood parameters. Therefore, usage of these probiotic(s) bacteria as antibiotic alternatives in poultry nutrition can be recommended. Progressive Agriculture 29 (4): 359-370, 2018

Abstract As an alternative to antibiotic growth promoters, live yeast supplementation has proven useful in reducing weaning stress and improving health and performance of piglets. The objective of the study was to evaluate the effect of a high concentrated live yeast product (20 billion CFU/g) supplemented in post-weaning piglet diets without antibiotics. A total of 144 pigs Pietrain × [LW×Landrace] (average initial BW = 8.55 ± 1.5 kg) weaned at 28 days of life were used for a 6-week growth study to determine post-weaning performance. Pigs were assigned to 2 treatments; 0 (Control group; CT) and 1 g of live yeast/kg (Yeast Supplemented group; YS) feed to 12 replicate pens of 6 pigs (3 barrows; 3 gilts). Average daily gain (ADG), feed intake (ADFI) and feed conversion ratio (FCR) were evaluated in pre-starter (days 0–14), starter (days 14–42) and in the whole nursery (days 0–42) periods. Data were analysed with ANOVA using PROC MIXED of SAS according to the completely randomized design. The model included initial BW as a covariant. Differences were deemed statistically significant when P ≤ 0.050 using a one tailed t-test. Live yeast supplementation improved ADG in starter (5.8%; P = 0.034) and in the whole nursery periods (7.0%; P = 0.045) compared with the CT group. Consequently, final BW was also higher in supplemented animals than in the CT (4.5%; P = 0.034). Differences in ADG were associated with differences in ADFI, higher in YS than in the CT group, both in starter (6.4%; P = 0.023) and in the whole nursery period (6.5%; P = 0.030). No differences were observed for FCR, mortality rate, and health incidences between dietary treatment groups. Therefore, supplementation of a live yeast to post-weaned piglets improved growth performance, confirming this product as an alternative to reduce antibiotic usage in nursery piglets.

This study was conducted with Thai broiler chicken (KKU 1) to investigate the effect of citric acid by-products from rice (CABR) on growth performance and villi histology. A total of 192 broiler chicks were subject to three dietary treatments, including 0% CABR, 3% and 6% of dry matter. Body weight gains, feed intake, feed conversion ratio, survival rate, and production index (body weight gain, feed intake, feed conversion ratio, survival rates, and productive index, respectively) were considered for growth performance evaluation. Villi height (µm), crypt depth (µm), and villi: crypt ratio were recorded for the villi histological measurement. The performance did not show a significant effect when compared with the control group during at ages ranging from 1 to 56 days. Villi histology indicate a significant effect on villi height (µm), crypt depth (µm), and villi: crypt of broiler chicks compared with the control group. Also, the use of 3% CABR caused a reduction microbial contamination in chicken fecal matter. In conclusion, supplementation of CABR had no negative effects on growth performance of Thai broiler chicken (KKU 1). Also, the addition of 3% CABR to the feed might help reduce fecal microbial contamination and affect the villi histology of Thai broiler chickens (KKU 1).

Aim: This study aimed to examine the effect of dietary Spirogyra jaoensis in starter feed on growth performance, pectoralis muscle (PM) growth, and small intestine morphology of broiler chickens. Materials and Methods: One hundred twenty one-day-old Cobb-500 broilers (body weight 46±2.6 g) were divided into four equal groups with 3 replicates in each group and given basal feed supplemented with dried S. jaoensis at doses of 0%, 0.5%, 1%, or 2%. The treatment was carried out until the chickens were 18 days old to examine growth of broiler chicks at starter period (8-21 days old). Results: Supplementation with S. jaoensis at doses of 0.5% and 1% resulted in increased weight and improved feed conversion ratio compared to the control group. At the end of treatment, chickens fed with 0.5% and 1% S. jaoensis weighed 428.3±47.8 g and 426.9±31.8 g, respectively, and were significantly heavier than the control group (373.1±44.1 g). Furthermore, parameters related to PM growth and small intestine morphology of chickens supplemented with 0.5% S. jaoensis in basal feed were improved compared to the control group. Conclusion: The results of this research indicate that S. jaoensis at a dose of 0.5% improves growth performance, PM growth, and small intestine morphology in broiler chickens. Keywords: broiler chicken, feed supplement, pectoralis muscle growth, small intestine, Spirogyra jaoensis.

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.
