Feed remains the most important cost in animal production. The need for feed ingredients, which will reduce the cost of production, is the basis for most livestock feed and production research. Man and his livestock are in competition for the basic ingredients. Availability of such feed ingredients thus becomes the key limiting factor in poultry production, hence the need for alternative and locally available feedstuffs. The presence of undegradable and complex carbohydrate, non-starch polysaccharides (NSPs) in some alternative and locally available feedstuffs exerts some anti-nutritional properties and thus can limit their use in livestock feeding (Yoruk et al., 2006). Worse still is the fact that chickens are not capable of hydrolyzing NSPs that mask protein carbohydrate (Petterson and Aman, 1989). Exogenous enzyme supplementation has been reported to be used in poultry diets to improve nutrient utilization, the health and welfare of the birds, product quality and to reduce pollution as well as to increase the choice and content of ingredients which are acceptable for inclusion in diets (Aderemi et al., 2006). Since most work with exogenous enzymes has been carried out to evaluate its effect on feed intake and growth characteristics of broilers, the aim of this study was to investigate the effect of graded level of feed enzyme Roxazyme-G® on the performance, carcass and meat qualities of broiler finishers.

The growing concern about the cost of feed ingredients, use of least cost feed formulation and maintenance of a reliable nutritional requirement for broiler birds irrespective of the season is almost compelling to look for alternatives. Thus, this experiment was conducted to evaluate the performance of broiler chickens fed rice milling waste (RMW) as a replacement for maize. Chemical composition of rice milling waste was determined, while eleven experimental diets each were formulated to contain RMW as replacement for maize at 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% and 100%. Three hundred (300), 7-day-old chicks were allocated to the 11 dietary treatments each having 3 replicate pens with 10 birds per pen in a Completely Randomized Design (CRD). Feed and water were provided ad libitum for 6 weeks. Growth performance, carcass yield, organ proportions and economics of production were monitored. Data were subjected to ANOVA at P<0.05. The result from the chemical composition showed that rice milling waste has 89.84% dry matter, 10.80% crude protein and 24.09% crude fibre, while the gross energy was 3789 kcal/g, this showed that RMW is suitable as feed ingredient and as well would not hinder absorption and nutrient utilization. The result of the growth performance showed that broiler chickens fed 10% - 40% RMW had greater average daily weight gain (55.33g- 47.97g), reached a greater slaughter and carcass weight (1500g – 1650g) and were more feed efficient than broiler chicken of the other treatments (P<0.05 for each). In addition, from an economical point of view birds fed 10 - 40% were superior to the other treatments where the cost/kg weight gained (N292.21K – N315.96K) were lower than the remaining treatment groups. Thus, the inclusion of RMW in diet of broiler chickens as a replacement for maize improved nutrient utilization and economic value. It can therefore be recommended that RMW can be used to replace maize between 10% -40% in the diets of broiler chickens.     La préoccupation croissante au sujet du coût des ingrédients alimentaires, de l'utilisation de la formulation d'aliments pour animaux les moins coûteux et du maintien d'une exigence nutritionnelle fiable pour les oiseaux de gril, quelle que soit la saison, est presque convaincante pour chercher d'autres solutions. Ainsi, cette expérience a été menée pour évaluer la performance des poulets à griller nourris aux déchets de fraisage du riz (le 'RMW') comme remplacement du maïs. La composition chimique des déchets de fraisage du riz a été déterminée, tandis que onze régimes expérimentaux ont été formulés pour contenir le 'RMW' comme remplacement pour le maïs à 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90% et 100%. Trois cents (300), poussins de 7 jours ont été alloués aux 11 traitements diététiques ayant chacun 3 stylos de répétition avec 10 oiseaux par stylo dans un design complètement randomisé (CRD). L'alimentation et l'eau ont été fournies ad libitum pendant 6 semaines. Les performances de croissance, le rendement de la carcasse, les proportions d'organes et l'économie de la production ont été surveillés. Les données ont été soumises à ANOVA (P<0.05) Le résultat de la composition chimique a montré que les déchets de fraisage du riz ont 89,84% de matière sèche, 10,80% de protéines brutes et 24,09% de fibres brutes, tandis que l'énergie brute était de 3789 kcal/g, ce qui a montré que le 'RMW' est approprié comme ingrédient d'alimentation et ainsi n'entraverait pas l'absorption et l'utilisation des nutriments. Le résultat de la performance de croissance a montré que les poulets a griller nourris 10% - 40% RMW avaient un gain de poids quotidien moyen plus élevé (55.33g- 47.97g), ont atteint un plus grand poids d'abattage et de carcasse (1500g - 1650g) et étaient plus économes en aliments pour des animaux que le poulet de gril des autres traitements (P<0.05 pour chacun). En outre, d'un point de vue économique, les oiseaux nourris de 10 à 40 % étaient supérieurs aux autres traitements où le coût/kg de poids gagné (N292.21 K – N315.96 K) était inférieur à celui des autres groupes de traitement. Ainsi, l'inclusion du RMW dans l'alimentation des poulets de poulet a griller comme remplacement du maïs a amélioré l'utilisation des nutriments et la valeur économique. Il peut donc être recommandé que le 'RMW' peut être utilisé pour remplacer le maïs entre 10% -40% dans les régimes des poulets à griller.

Distillers dried grains with solubles (DDGS) is a coproduct of corn-based ethanol production that can be a valuable source of energy, digestible amino acids, and available phosphorus in poultry feeds. Dietary incorporation of DDGS reduces the amount of primary ingredients such as corn and soybean meal needed to formulate poultry diets, improving the sustainability of both biofuel and poultry production. The nutritional value of DDGS has been extensively evaluated since it became increasingly available to feed producers in the early 2000s, but evolving methods of ethanol production and coproduct fractionation necessitate its continued characterization. Attempts to relate nutrient utilization of DDGS to its chemical composition have revealed that fiber content is a primary determinant of dietary energy value of DDGS for poultry. Distillers corn oil, which is extracted from thin stillage during production of distillers grains, can also be supplemented into poultry diets as an energy-dense lipid source in place of animal fats or other vegetable-based oils. Poultry feeding practices in the United States are also evolving, including increased adoption of all vegetable-based diets and reduced use of in-feed antimicrobials. Therefore, further characterization of both the nutritional value of DDGS and its impact on gastrointestinal health will support its continued use in poultry diets.

The goal of the research was to investigate the effect of dietary natural or biotic additives such as garlic, black pepper, and chili pepper powder in poultry nutrition on sustainable and economic efficiency of this type of production. A total of eight dietary treatments with 1200 broiler chickens of hybrid line Hubbard were formed, with four replicates. During the experimental period, chickens were fed with three period mixtures diets of different average costs: Starter compound mixture two weeks (0.38 €/kg in all treatments), grower compound mixture next three weeks (0.36, 0.38, 0.40, 0.41, 0.46, 0.39, 0.42, and 0.39 €/kg, respectively), and finisher compound mixture for the final week (0.34, 0.36, 0.38, 0.39, 0.44, 0.37, 0.40, and 0.37 €/kg, respectively). The experiment lasted a total of 42 days. Upon finishing the experiment, results have shown statistically significant (p < 0.05) differences regarding the European broiler index (EBI) as one of the indicators of economic efficacy. The EBI was lowest in the control treatment (220.4) and significantly higher in experimental treatments (298.6), respectively. In cost, a calculation included the cost of feed and used natural or biotic supplements in chicken nutrition. The findings of the study of economic efficiency revealed that the cost per treatment rises depends on the natural additive used. Economic efficiency analysis showed that the most economical natural additive with the lowest cost is garlic (0.68 €/kg), while the most uneconomical is treatment with black pepper with the highest cost of body weight gain (0.82 €/kg). This higher cost of the gained meat is minimal as a consequence of a much healthier and more nutritious food meant for human use, which often promotes sustainable aspects, compared to conventional and industrialized poultry production.

The main task in meat poultry production is to obtain products in a short period of fattening with the minimum feed costs. In economic terms, fodders occupy the largest share in the cost structure of poultry meat. The feed in its composition and properties should satisfy the physiological needs of the chicken, as much as possible, and this, in turn, directly depends on its usefulness and quality. In this regard, the actual issue of feeding is the use of antioxidants to improve the conservation of feed and optimize metabolism in the body of the bird. The inclusion of “Bisfenol-5” antioxidant in full-feed mixed doses in doses of 0.002-0.015% of the feed weight positively affected the growth rate of broiler chickens and feed conversion. The highest effect was obtained with the addition of “Bisfenol-5” in the amount of 0.008% to the compound feed. The use of antioxidant-enriched mixed fodder for growing chicken broilers allowed to increase meat production to 17.5%, to increase feed conversion to 12.1%, to reduce the cost of 1 kg of live weight gain to 6.99 rubles and to improve the efficiency index to 0.2 points.


It is known that today in the field of feeding animals and poultry, the use of dietary supplements, or premixes, is relevant. However, it should be noted that the premix quality mainly depends on the filler. Due to the above, the authors have performed comprehensive studies of the possibility to use fodder concentrate and the Sarepta vegetable raw material as a filler in the composition of premixes for cattle and poultry diets. In studying the nutritional value and the technological properties, the new filler was favorably different from the one traditionally used (sunflower meal). In the course of the research of using premixes and protein vitamin-mineral concentrates with the new filler in the composition of the fodder for agricultural animals and poultry, the following positive results were obtained: during the main period of experiment, milk yield of the dairy cows increased by 7.40 %; milk quality also improved, the value of byproducts from a single animal amounted to 4,928 rubles; the live weight of the dairy calves increased by the age of six months by 1.7 %, which amounted to 7,560 rubles of additional growth; during the period of experiment, egg productivity of the laying hens increased by up to 1.73 %, and the economic effect was 1,142.73 rubles; the live weight of the broiler chickens increased by 10.2 %, the slaughter yield of carcasses increased by 1.9 %, with that, the additional profit per animal was about 55.51 rubles. Based on the comprehensive research, one can recommend introducing the premix with the Sarepta concentrate to the diets of cattle and poultry to increase their productivity, improving product quality and economic efficiency of the livestock breeding industry and poultry production.

ABSTRACT  A study was conducted to determine the best means of processing cassava and soybeans together in a suitable proportion to produce a concentrate of good physical and nutritive quality for feeding to poultry. Samples of cassava and soybeans were subjected to six different processing techniques and mixed together in different proportions viz. 80:20, 60:40 or 50:50. The processing techniques were as follows; toasted soybeans and dried cassava chips were mixed together and ground in sample A while toasted soybeans and cassava were ground separately before mixing in sample B. Samples C and D included raw cassava and soybeans mashed together before being sun-dried or oven dried respectively. For samples E and F raw cassava and soybeans were boiled together before being sun-dried or oven-dried respectively. Results showed that when cassava and soybeans were boiled together and dried, the product was of good physical texture as indicated by its flaky texture. Nutritive quality was also high in terms of protein and energy contents. For these samples, sun drying was preferred to oven-drying due to the ease of the method of drying as well as the cheaper cost involved in drying. Proportions of either 50:50 or 60:40 are preferred to take advantage of both energy and protein contents of the final product.Reasonable prices have stimulated poultry production. In Nigeria, however, the major crops for livestock feeding being corn, soybeans and groundnut are widely used for human consumption... Hence there is increasing.

The development of antibiotics-resistance pathogens in poultry which poses threat to human health has necessitated the search for alternative to antibiotic growth promoters (AGPs) to improve gut microflora in poultry diets. One of the alternatives to AGPs is probiotics which are beneficial organisms. The prebiotic potentials of enzyme supplemented high fibre feedstuffs (HFFs) are not known. This study was conducted to assess the prebiotics potential of xylanase enzyme supplemented rice husk (RH) on broiler chickens (in-vivo). The study showed that replacement of maize with RH irrespective of levels supplemented with 100ppm xylanase enzyme caused a reduction in feed intake and an increase in weight gain and better FCR. It was observed that birds fed diet with 10% RH supplemented with xylanase enzyme out-performed birds fed diets with 20 or 30% RH supplemented with xylanase enzyme and closer to the birds fed the control diet which was with better FCR. Enzyme supplementation of RH helped in increasing and improving protein, ether extract and fibre digestibilities. The identification of microbes (Fungi and Bacteria) showed that dietary levels of RH (10, 20 or 30% inclusion) with supplementation of enzyme xylanase enhanced the growth of beneficial microbes which resulted in inhibition or elimination of the opportunistic/pathogenic microbes. The result of the cost benefit analysis also showed that 10% inclusion level of RH supplemented with xylanase enzyme gave the best result of a beneficiary reduction in the cost of production with the best improved broiler performance. The use of enzymes is therefore recommended when RH are required as prebiotic source in the gut of broilers.

The consumer price for poultry products in Nigeria and the expansion of the commercial poultry industry are negatively affected by the utilization of competitive and costly ingredients in making poultry diets. Consequently, the identification and utilization of locally available alternatives would greatly reduce cost of poultry production and products. In this regard, a study was undertaken to examine the effects of replacement of yellow maize (YM) with gayamba pearl millet variety as dietary energy source on carcass yield and blood parameters of broiler chickens. Three hundred (300) Ross 308 broiler chicks weighing 167.94 – 173.07g were randomly assigned to four dietary treatments of 75 birds each. Each treatment was replicated thrice with 25 birds in a completely randomized design. The experimental diets contained 0, 33.33, 66.67 and 100% gayamba millet as replacement for YM designated as diets 1, 2, 3 and 4 respectively. Full-fat soya bean and groundnut cake meal were the main vegetable protein sources used in the diets. Feed and water were provided ad libitum and the experiment lasted for 49 days. Results for carcass yield indicated a significant (P<0.05) influence of diet on live weight (1828.33 – 2316.66 g), plucked weight (1622.83 – 2132.83 g), eviscerated weight (1429.50 – 1883.47 g) and carcass weight (1277.66 – 1680.33 g) in favour of diet 3. However, dressing percentage (69.00 – 72.50%) did not differ among treatments. In the same way, most of the relative weights of organs were also not significantly affected by diet. Except for the packed cell volume (29.81 – 35.04%), none of the haematological parameters showed significant difference among the treatments. Similarly, most of the serum biochemical indices apart from total proteins, albumin and globulin, did not differ significantly among treatments. It was therefore concluded that gayamba pearl millet can completely replace yellow maize in broiler chickens' diets with no adverse effect on carcass yield and blood constituents.

In developing nations Nigeria inclusive, most of the cereals grown are for human consumption. Conventional feedstuffs use in livestock production especially in poultry enterprise has intensified the competition for available grains. Consequently, the cost of poultry production is jacked up. Since poultry provides most of the animal protein consumed either in the form of meat or egg, exploring tropical vegetables as a route of escape to reducing the cost of feeding will be a great gain in the poultry enterprise. Tropical vegetables especially the African leafy vegetables (ALVs) are economical and highly nutritive possessing good levels of vitamins, minerals, protein and essential amino acids. The mineral constituent of some tropical vegetables as well as their nutritive impact on the performance, meat quality, egg quality in broiler and laying birds as presented in this review paper. Although, the availability of ALVs all year round, its moisture content level and presence of anti-nutrients may tend to limit its usage in poultry feed, adopting irrigation techniques and improved seedlings as well as exploring the processes of enhancing the nutritional value of ALVs to combat anti-nutrients to tolerable levels by the birds make it possible to be considered as good alternative in poultry diets.

In order to save soybean meal, sunflower oil and reduce the cost of rations, new sources of raw materials can be used. In modern conditions, attention is drawn to the spring colza, the seeds of which can be used as a fat and protein supplement. A limiting factor in the use in poultry nutrition is the presence of glucosinolates in the seeds and erucic acid in the oil, which negatively affect the growth and development, especially of young animals. Breeding work aimed at improving the feed qualities of spring colza seeds contributes to a wider use in the composition of diets for poultry. In growth experiments on broiler chickens the rate of introduction of seeds of spring colza of the 'Nadezhda' variety selected by the Federal Williams Research Center of Forage Production and Agroecology. It has been established that this variety belongs to the "canola" varieties, and its seeds can be included up to 7% (by weight) in the feed composition without adversely affecting the state of the body and the rate of growth of live weight of chickens. The use of colza seeds reduces the use of soybean meal to 4.7% and sunflower oil to 2.3 % (relative). Increases the efficiency of feed in the control up to 61.93% and in the experimental groups (I, II, III, IV) – 62.18, 62.51, 63.62, 62.78%, respectively. The seeds of the spring colza variety 'Nadezhda' satisfy the bird's need for nutrients and ensure equal productivity with the control
