L’objectif de ce travail est de rechercher une voie alternative d’amélioration de l’alimentation et de la productivité avicole au Burkina Faso. L’étude vise à évaluer les effets de l’incorporation de la farine d’Azolla pinnata dans la ration alimentaire sur les performances de croissance des poulets de chair. Pour ce faire, une expérience a été conduite pendant 56 jours avec 120 poussins de chair âgés de 21 jours afin d’évaluer l’effet de l’incorporation de la farine d’Azolla pinnata comme ingrédient alimentaire dans la ration de poulets de chair. Le soja torréfié utilisé comme témoin a été substitué partiellement par la farine d’A.pinnata à des taux de 0, 3 et 6% correspondant à trois traitements alimentaires R0, R1, R2. A la fin de l’essai, une augmentation du poids des sujets avec les apports croissants d’A. pinnata dans les rations (R1 et R2) a été observée même si elle n’a pas été significative. Les indices de consommation n’étaient pas significativement différents. L’incorporation n’a engendré aucun effet néfaste sur le rendement carcasse des sujets nourris à base de la farine d’Azolla en comparaison aux sujets témoins. La substitution partielle du soja torréfié par la farine d’Azolla aux taux de 3% et 6% a entraîné une diminution des coûts alimentaires par kg de poids vif de poulet.Mots clés : Aviculture traditionnelle améliorée, Azolla pinnata, poussins hybrides, performance de croissance.   English Title: Effects of incorporating dried azolla (Azolla pinnata) biomass in chicken rations in improved traditional poultry farmingThe objective of this work is to look for an alternative way to improve poultry feed and productivity in Burkina Faso. The study aims to evaluate the effects of the incorporation of Azolla pinnata meal in the feed ration on the growth performance of broilers. To this end, a 56-day experiment was conducted with 120 21-day-old broiler chicks to evaluate the effect of incorporating Azolla pinnata meal as a feed ingredient in the broiler ration. The roasted soybean used as a control was partially substituted with A. pinnata meal at levels of 0, 3 and 6% corresponding to three feed treatments R0, R1, R2. At the end of the trial, an increase in the weight of the subjects with increasing A. pinnata intakes in the rations (R1 and R2) was observed, although it was not significant. The consumption indices were not significantly different. Incorporation had no adverse effect on carcass yield in subjects fed Azolla meal compared to control subjects. Partial substitution of roasted soybean with Azolla meal at 3% and 6% resulted in lower feed costs per kg live weight of chicken.

Soya bean, a conventional plant protein source in poultry feeding has become so costly and occasionally scarce resulting in high cost of poultry feed. The replacement of soya bean is therefore necessary to improve production. This study evaluated the effects of Euphorbia heterophylla (Spurge weed) leaf meal (EHLM) on the growth performance and nutrient digestibility of One Hundred and Eighty (180) Ross 308 strain of broiler chicks. They were randomly allotted to six (6) experimental diets with three replications of ten bird each and fed for 28 days. Diets were formulated such that EHLM was included as 0, 5, 10, 15, 20 and 25% levels for T1, T2, T3, T4, T5 and T6 which replaces soya bean meal in the basal diets. Data collected were subjected to analysis of variance in a completely randomized design. Results indicated that the average daily feed intake, average daily weight gain, average daily protein intake, protein efficiency ratio and average final live weight, were significantly different (P<0.05) among treatment groups while average feed conversion ratio and mortality were not affected. Digestibility coefficient of CP, CF, EE, NFE and Ash showed significant different(P<0.05) among treatment groups. However, bird fed T2, T3 and T4 digest nutrient efficiently compared with the control than T5 and T6. It was therefore concluded that upto 15% EHLM levels could be adopted for optimum growth performance and nutrient digestibility in broiler chicks aged 0-4 weeks.     Le soja, une source conventionnelle de protéines végétales dans l'alimentation de la volaille, est devenu si coûteux et parfois rare, ce qui entraîne un coût élevé de l'alimentation de la volaille. Le remplacement du soja est donc nécessaire pour améliorer la production. Cette étude a évalué les effets de la farine de feuilles (EHLM) d'Euphorbia heterophylla (euphorbe ésule) sur les performances de croissance et la digestibilité des nutriments de la souche cent quatre-vingt (180) Ross 308 de poulets de chair. Ils ont été répartis au hasard dans six (6) régimes expérimentaux avec trois répétitions de dix oiseaux chacun et nourris pendant 28 jours. Les régimes ont été formulés de telle sorte que l'EHLM a été inclus en tant que niveaux de 0, 5, 10, 15, 20 et 25 % pour T1, T2, T3, T4, T5 et T6 qui remplace le tourteau de soja dans les régimes de base. Les données recueillies ont été soumises à une analyse de variance dans un plan complètement randomisé. Les résultats ont indiqué que l'apport alimentaire quotidien moyen, le gain de poids quotidien moyen, l'apport protéique quotidien moyen, le ratio d'efficacité protéique et le poids vif final moyen étaient significativement différents (P< 0,05) entre les groupes de traitement, tandis que le taux de conversion alimentaire moyen etla mortalité n'étaient pas affectés. Le coefficient de digestibilité de CP, CF, EE, NFE et Ash a montré une différence significative (P<0,05) parmi les groupes de traitement. Cependant, les oiseaux nourris avec T2, T3 et T4 digèrent efficacement les nutriments par rapport au témoin que T5 et T6. Il a donc été conclu que jusqu'à 15 % de niveaux d'EHLM pouvaient être adoptés pour des performances de croissance optimales et une digestibilité des nutriments chez les poulets de chair âgés de 0 à 4 semaines.

Dietary Treatments

The influence of insect protein origins on broiler chicken meat parameters were studied using 135 day old Arbor acre birds subjected to three dietary treatments: Diet A comprised of a standard feed of the brand name ‘vital feed’ containing fishmeal as the major protein source (control), while Diet B and Diet C contained insect meal from African palm weevil larvae (Rhynchophorus phoenicis), respectively, winged termite (Macrotermes bellicosus) as replacement for fishmeal. Forty five broiler chicks were randomly assigned to each of the dietary treatments at the rate of fifteen chicks per replicate making three replicates per treatment in a completely randomised design. The experiment lasted for eight weeks. During this period, the birds were housed in similar cages and subjected to similar husbandry and sanitation practices, such that the only source of variation was the dietary treatments. After eight weeks of the experiment, carcass quality and organ weight measurements were analysed using appropriate statistical analysis. The result obtained showed that the broiler chickens fed insect meals performed significantly (P<0.05) better in terms of live weight gain (2,200.85±64.23 g and 2,046±58.40 g for Diet B and Diet C) compared to control. Carcass quality relating to defeathered weight and eviscerated weight also followed a similar trend with Diet B (2,187.74±62.72 g and 1,788.93±70.70 g), Diet C (2,015.83±74.62 g and 1,466.97±100.05 g), and Diet A (control; 1,526.47±47.40 g and 1,240.30±64.53 g). The records of cut-up parts and organ weight measurements were also significantly different (P<0.05) for the birds on insect meal (Diet B and Diet C) than those on fishmeal based diet (Diet A). The result showed that insect meal can effectively serve as a major source of protein in poultry feed formulation.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

The effect of vitamins, minerals and probiotics supplementation to the balanced ration of the broiler chicks on the immune response and growth performance after vaccination with BCRDV was evaluated. For this 50 broiler birds were divided into five equal groups such as A, B, C, D and E, and five types of separate treatments with normal poultry feed were provided to the indivisual experimental groups. All the birds were vaccinated with BCRDV primarily at 3 days of age and boostered at 17 days of age. The birds of group A, B, C and D were supplemented with only probiotics, mixture of probiotics and minerals, mixture of probiotics, minerals and vitamins, respectively. The birds of group E were kept as vaccinated control. Blood samples were collected at the age of 9, 12, 16, 23, 26 and 30 days sequencially. The serum antibody titres were measured by HI test and ELISA. The highest value of HI antibody titre was 384±242.65 (Mean ±SD) in group B at 23 days of age. The lowest value of HI at 23 days was 56±32.86 (Mean ±SD) obtained in group C. The ELISA antibody titre was also highest (4675.12±485.72) at 23 days in group B and obviously the lowest (2169.38±724.45) in control group E. In case of group C, the ELISA antibody titre was 3105.73±877.57 at 23 days but then the titre decreased gradually compared to control group. The highest body weight (1420±90.82) was recorded at 30 days of age in group D and the lowest value (1188±44.38) was in group B.

Feed Costs

Background: The presence of inadequate and inconsistent feeds to the chicken resulted in lower performance of chick production in Ethiopia. Broilers are meat type chickens with fast income generation and depend on high quality feed. Feed costs alone currently account for over 65-70% of poultry production in third world countries, there has been recent interest in determining the feeding value of different locally available alternative feeding resources. As fish is generally appreciated as one of the healthiest and cheapest source of protein and it is available in Gambella water bodies, this research is intended to investigate the effects of fish by-product inclusion in broiler feeds on growth performance. Two hundred and forty (240) day old broiler chicks (Cobb 500) were reared and assigned to four treatments for 42 days. Treatment one was the control without fish by-product meal, treatment 2 contained 2% fish by-product meal, treatment 3 contained 3% fish by-product meal and treatment 4 contained 5% fish by-product meal. Each treatment was replicated 3 times with 20 birds per replicate in a completely randomized design. Parameters measured for the experiment were the initial body weight, final weight, daily feed intake while weight gain and feed conversion ratio (FCR) were calculated. Data were analyzed using General linear model procedure of statistical analysis software (SAS) version 9.2. Results: This study indicated that the average daily feed intake of broiler significantly increased (P<0.05) in 3 and 5% fish by-product meal level to the diets during 11-20 days of age. At the age of 32 – 42 days the average body weight and daily feed intake at the age of 21-32 days were significantly (P<0.05) increased in 3 and 5% fish by-product meal level compared to control and 2% fishmeal diet. Conclusion: This study revealed that inclusion of fish by-product meal in the diet improved the performance of broiler. To utilize and exploit the potential of fish by-product meal as broiler feed in Gambella region, farmers should get training on preparation and utilization of fish by product.

A study on azolla as an economical substitute to soybean based poultry feed was conducted. The experiment consisted of four treatments laid out in Completely Randomized Design (CRD) with five replications. Each experimental unit consisted of three birds. For this purpose, eight-day old, unsexed Hubbard broiler chicks were weighed and randomly assigned to each treatment. Four different levels of azolla meal were incorporated in the starter and finisher ration at a level of 0%, 10%, 15%, and 20% respectively. Body weight, weight gain, feed consumption, and feed efficiency were measured. The average cumulative weekly body weight for all weeks were found to be significantly different (P<0.05) for the various treatments. Maximum cumulative body weight (1360 g) was found in broiler fed T2 ration in 5th week. Similar trend was also observed in 6th week showing highest cumulative weight (1882 g) in control diet (T1) which was at par with T2 (1841 g). Significantly highest (420.3 g) live weight gain was observed in T2 diet during 5th week. Overall mean of weekly feed consumption was recorded highest (784.33 g) in T2 diet. The economic analysis of net income/kg live weight was the highest (Rs 18.86) in T1 which was at par with T2 (Rs 18.35). Likewise, cost of production/bird was highest (Rs 124.5) in T1 and lowest (Rs 112.2) in T4. The results show that azolla meal could be utilized to substitute up to 10% soybean meal from overall production and economic point of view.Int J Appl Sci Biotechnol, Vol 3(4): 619-625

An study was conducted on "Cobb-500" broiler chicks to evaluate the effects of probiotics and enzymes supplementation on growth performance, haematological and biochemical parameters. A total of 20, fourteen days old broiler chicks were divided randomly into four groups using five broiler chicks in each group. Group A was designated as control group was given only normal broiler ration and rest of the groups were fed probiotics and enzymes, [Group B (probiotic Microguard® @ 1 gm/L), Group C (enzymes preparation Acmezyme* 1 gm/L), Group D (Microguard* g 1 gm/L and Acmezyme @ 1 gm/L)] with drinking water respectively from 1St to 21st day of study. It was observed that probiotics and enzymes supplementation enhanced the body growth rate. At the final day of experiment the body weight was significantly increased (P<0.01) in the treated groups in comparison with that of control group. Total Erythrocyte Count (TEC), Hemoglobin (Hb) concentration, Packed Cell Volume (PCV) were significantly increased (p<0.01) in treated groups than the control group. Erythrocyte Sedimentation Rate (ESR) and Serum alanine aminotransaminase (ALT) levels were decreased significantly (p<0.01) than the control group. The serum Serum aspertate aminotransaminase (AST) level was decreased significantly (p<0.01) in all treated groups except group D than the control group. It is suggests that the poultry farming may be benefited using probiotics and enzymes. DOI: http://dx.doi.org/10.3329/jbau.v11i1.18221 J. Bangladesh Agril. Univ. 11(1): 111-118, 2013

Different Levels

High ambient temperature reduces feed intake, live weight gain, and feed efficiency (Siegel, 1995), thus negatively influencing the performance of broilers. Heat stress has also been shown to suppress immune responses of broiler. Chromium is an essential nutrient required to promote the action of insulin in body tissues so that the body can use sugars, proteins and fats. Cr deficiency can disrupt carbohydrate and protein metabolism, reduce insulin sensitivity in peripheral tissues and impair growth rate (Vincent, 2000).Chromium is important in altering the immune response by immunostimulatory or immunosuppressive processes as shown by its effects on T and B lymphocytes, macrophages and cytokine production. Dietary chromium supplementation has been reported to have a positive effect on growth rate and feed efficiency of growing poultry under stress conditions (Sahin et al., 2002). Another reason for supplementing chromium is due to the fact that chromium is excreted excessively during stress (Anderson, 1994). Also the dietary requirement of livestock for chromium has not been defined yet (NRC, 1997). This study was to investigate the effects of different levels of Cr nicotinate on the growth performance and antibody titres against Newcastle and Influenza disease in broilers.

A total of 300 day-old Hubbard Classic broiler chicks were reared to investigate the effect of dietary inclusion of 2, 3, 4 and 5% of palm oil on feed consumption, growth performance and profitability of broiler. Addition of 4% palm oil in diet found to attribute additive effect on the growth of the bird from 2nd to 4th week of the trial. Broilers of 2 and 3% oil added group attained 1791g and 1777.67g live weight, respectively which was 4% and 3% higher than that of the control. Similar effect of different levels of palm oil was also observed in case of live weight gain. Dietary inclusion of palm oil improved feed consumption and significantly (P<0.05) higher feed consumption was recorded in 4% palm oil group than 5% oil group. From the economic analysis on production cost of broiler, it was found that total cost per broiler was the lowest in control group (Tk. 115.92), which was lower by Tk. 8.23, 7.46, 9.13 and 2.68 than the 2%, 3%, 4% and 5% oil added groups, respectively. Profit earned from each group (Tk/broiler and Tk/kg broiler) was statistically similar (P>0.05). It can be concluded that profitable broiler production might be possible without supplementation of palm oil.

A 21-d investigation was conducted to ascertain the effect of 50% whole millet grain replacement for milled millet on growth performance, gastrointestinal conditions and development in broiler chickens. Eighty-four one-day-old unsexed broiler chicks were randomly allotted to two treatment groups with 7 replicates of 6 chicks per replicate. Two diets; whole millet diet (WM), consisting of 50% of the millet provided as whole grain, and the ground millet diet (GM), as the control, were formulated and fed ad-libitum throughout the study period. Performance data: feed intake, daily live weight gain and feed conversion ratio were recorded weekly, i.e. at 7, 14 and 21d, while gastrointestinal assessment: jejunal, digesta pH, relative weights of the proventriculus, gizzard, pancreas and liver, and jejunal and ileal morphometry were conducted on 21d. Similarities (p > 0.05) were observed in the growth performance, digesta pH and relative weight and length of duodenum, jejunum, ileum and caeca for chickens in both treatments. A 25.7% increase in gizzard weight was observed in chickens on WM, as well as significant (p < 0.05) increases in jejunal and ileal height and jejunal villus width were recorded on the chickens. A significant reduction in flock uniformity was observed in chickens fed the whole millet diet at 14d. It could therefore be concluded that 50% whole millet grain replacement for milled millet resulted in similar growth performance and improved gastrointestinal function and activity in 21-d post hatch chickens.
