AbstractLipids (fats and oils) are concentrated source of energy in poultry diets that improves palatability, feed consistency, provides essential fatty acids and increases the absorption of fat-soluble vitamins. Fresh oil is an expensive energy source and its exposure to air, heat, metallic catalyst during storage and processing may lead to its oxidative deterioration. This review highlights the response of modern poultry to dietary oxidized oil on growth performance, nutrients digestibility, gut health, carcass characteristics, meat quality, blood chemistry and tissue oxidative status. Literature shows that in moderately (peroxide value (PV): 20 to 50 meq kg−1) and highly (PV: 50 to 100 meq kg−1 or above) oxidized oils, lipid peroxidation causes rancid odours and flavours that negatively affect feed palatability, reduces intestinal villus height that decreases the surface area available for nutrients absorption. The oxidation products also damage fat soluble vitamins (A, D, E and K) in blood resulting in an oxidative stress. The use of oxidized oil in poultry diets has no significant effect on dressing percentage, pH and meat colour, whereas carcass weight decreases and drip loss of meat increases. Overall, there is a contradictory data regarding the influence of oxidized oil in poultry feed depending on the PV and inclusion levels. The reviewed literature shows that the use of mildly oxidized (PV < 20 meq kg−1) oil in poultry feed with 4 to 5% inclusion level decreases the feed cost and ultimately cost of poultry production without compromising their growth performance. It can, therefore, partially replace fresh oil as an efficient, cost effective and sustainable energy source in poultry diets.

The use of supplementary fat in commercial poultry diets has been wide-spread since the 1960s. In addition to their value as a dense source of energy, supplemental fats are an excellent source of essential fatty acids and enhance the absorption of fat soluble vitamins. The efficiency of nutrient digestion in poultry largely depends on the microorganisms which live naturally in its digestive tract (Apajalahti et al. 2003). It has been reported that intestinal microflora influences the absorption of fats (Pesti, 2002).Today, antibiotics and probiotics are used for manipulating the gut microflora in poultry production and act as growth-promoting agents. Thus, using these growth promoters (GP) will probably affect nutrients absorption, especially of dietary fats. The aim of this study was to evaluate the effects of supplementary antibiotics and probiotics in diets containing different levels of fat on broiler performance.

Oxidative stress is inevitable in poultry production, and it affects the physiological, behavioral and biochemical status of growing chicken which ultimately deteriorates meat quality. Appearance, texture, juiciness, tenderness and odor are responsible for the overall meat quality as they are essential perceptible features, which determine the consumer’s judgment. Overproduction of free radicals including reactive oxygen species (ROS) disturbs the mitochondrial function in living cells. During high-temperature mitochondrial substrate oxidation and electron transport chain (ETC) activity increases. This increased activity results in excessive production of superoxide that oxidizes protein and lipid contents in muscle tissues. By oxidizing protein and lipid, ROS spoils the nutritive quality of chicken meat. High ambient temperature is one of the major contributing factors that enhance oxidative stress. Poultry feed with anti-oxidant supplementation and innovative processing techniques can help the poultry industry to overcome oxidative stress.

Abstract Feeding oxidized oils can cause adverse effects on the growth performance of broilers, which have largely attributed to the presence of lipid oxidation products (LOP) in oxidized oils. This study was conducted to identify the potential correlations between growth performance and aldehyde profiles of differently-prepared thermally oxidized soybean oils. Seventy-seven broilers were randomly assigned to one of seven diets containing 7.5% fresh soybean oil or thermally oxidized soybean oil (OSO), including 1) 22.5°C, 0h; 2) 45°C, 336h; 3) 67.5°C, 168h; 4) 90°C, 84h; 5) 135°C, 42h; 6) 180°C, 21h; 7) 225°C, 10.5h, respectively. Broilers were provided ad libitum access to experimental diets for 28 days. Broilers body weight (BW) and feed intake were recorded weekly to calculate the average daily gain (ADG), average daily feed intake (ADFI), and gain to feed (GF) ratio. The aldehydes in these oils were determined by the liquid chromatography-mass spectrometry (LC-MS) analysis. The correlations between individual aldehydes and ADG, ADFI, or GF were examined by partial least squares (PLS) analysis. Feeding 135°C, 42h oxidized oil significantly decreased the ADG, ADFI, and GF value compared with other groups (p < 0.001). Among 17 aldehydes identified in thermally oxidized soybean oils, C9-C11 unsaturated alkenals, including 2-decenal, 2-undecenal, 2,4-nonadienal, 4-hydroxy-2-nonenal, 2,4-decadienal, and 2,4-undecadienal, had better inverse correlations with growth performance than C5-C8 saturated alkanals in broilers, suggesting different toxic effects from these aldehydes.

Background Natural minerals have many beneficial properties in poultry production, taking into account production as well as hygiene, health, safety, and quality of broiler meat. The aim of the study was to evaluate the effect of aluminosilicates in feed and litter on the growth performance and meat quality in chickens. Aluminosilicates, including halloysite and zeolite, could be a good alternative for synthetics, as a good solution for the environment in line with the current trends. Methods Five-hundred male Ross 308 chickens were managed in 5 groups (10 replicates/group): LITTER: 1, control; 2, 0.95 kg/m2 of halloysite; 3, 0.475 kg/m2 of halloysite and 0.475 zeolite; 4, 0.95 kg/m2 of zeolite; 5, 0.25 kg/m2of halloysite and 0.7 kg/m2 of zeolite. FEED: groups 2–5, halloysite and zeolite addition (25:75 ratio; 0.5–2%). Growth performance (body weight and feed indicators), carcass, and meat quality (pH, colour, water-holding capacity, chemical composition of muscles) were recorded. The experimental setup, where the aluminosilicate additives were applied simultaneously, was proposed and approved by experts after pilot testing and on the basis of extensive literature where feed or litter additives were tested. Results Body weight and its gain were higher in groups 3 and 4 than in 1, and feed intake was higher in 4. The weight of the carcass and some of its components, including muscles and skin with subcutaneous fat, were higher in 2–4. Water loss from leg muscles was lower in 4. The content of protein in muscles was significantly higher in 3. The addition of aluminosilicates in feed and litter had a positive effect on the growth performance and some traits of carcasses and meat quality, especially in group 3. Halloysite and zeolite can be used in feed and litter (especially 0.475 kg/m2 for each mineral in the wheat litter).

Black soldier fly (BSF) larvae and pre-pupae could be satisfactorily raised on household organic waste and used as poultry feed, offering a potential sustainable way to recycle untapped resources of waste. The present study was conducted to determine if whole (non-defatted) BSF larvae and pre-pupae raised on experimental household waste could substitute soybean meal and oil as ingredients for laying hen diets. While no significant differences in feed intake and the egg-laying rate of hens were observed throughout the experiment, egg weight and eggshell thickness were greater in the pre-pupae-fed group than in the other groups. Moreover, although diversity of the cecal microbiota was significantly higher in the pre-pupae-fed than in the control group, no significant differences in bacterial genera known to cause food poisoning were observed when comparing the treatment groups. Nonetheless, Lactobacillus and Bifidobacterium populations were significantly lower in the treatment than in the control group. Fat content in BSF was possibly related with the changes in the cecal microbiota. Hence, since BSF fat was deficient in essential fatty acids, special attention should be paid to the fat content and its fatty acid composition in the case of regular inclusion of BSF larvae and pre-pupae oil as an ingredient in poultry diets.

La qualité des aliments de ponte est l’élément le plus important duquel dépendent les caractéristiques physiques et nutritionnelles des œufs. L’incorporation d’huiles végétales dans l’alimentation des pondeuses confère à cette alimentation, un apport en acides gras essentiels tel que l’acide linoléique. L’huile de soja est une huile végétale riche en acides gras polyinsaturés et a une forte concentration en acide linoléique, essentiel au bon fonctionnement de la ponte. Objectif : Ce présent travail se propose d’évaluer les effets de la supplémentation des aliments ponte à l’huile de soja sur le poids et la taille des œufs de poules pondeuses Warren. Méthodologie et résultats : L’expérience a porté sur 150 Warren de 20 semaines d’âge (entrée en ponte), scindés en 3 lots de 50 poules chacun. L’huile de soja a été introduite dans les aliments à raison de 0% (Lot 1 : Témoin), 2% (Lot 2) et 4% (Lot 3). Les aliments ainsi fabriqués ont été distribués quotidiennement aux poules. Les premières données de l’expérience ont été recueillies après un mois de ponte (25e semaine). Ces données ont permis de déterminer le poids et la taille des œufs collectés. Après 7 mois d’expérience, les résultats ont montré qu’une supplémentation de 2% et 4% d’huile de soja a permis d’améliorer le poids respectivement de 2,49 g et 1.36 g. Pour la taille des œufs, l’incorporation d’huile de soja à 2% et 4% donne des valeurs similaires mais supérieures à celles du lot témoins (0%). Conclusions et application des résultats : L’huile de soja se présente donc comme un outil d’amélioration du rendement des productions avicoles. Une application de l’utilisation de cette huile dans l’alimentation des volailles serait un atout pour le secteur avicole et permettra une amélioration du revenu des producteurs Mots clés : Aliments de ponte, huile de soja, acide linoléique, œufs.

Biosci. 2020 Influence de l’huile de soja sur le poids et la taille des œufs des poules pondeuses « Warren » 16072 Influence of soybean oil on the weight and size of the eggs of laying hens "warren" ABSTRACT The quality of the laying feed is the most important element on which the physical and nutritional characteristics of eggs depend. The incorporation of vegetable oils in the diet of the layers gives this diet a supply of essential fatty acids such as linoleic acid. Soybean oil is a vegetable oil rich in polyunsaturated fatty acids and has a high concentration of linoleic acid, which is essential for proper egg laying function. Objective: This present work aims to evaluate the effects of soybean oil laying feed supplementation on the weight and size of eggs from Warren laying hens. Methodology and results: The experiment involved 150 Warren 20 weeks old (entry laying egg), divided into 3 lots of 50 hens each. Soybean oil was introduced into foods at a rate of 0% (Lot 1: Control), 2% (Lot 2) and 4% (Lot 3). The feed thus produced was daily distributed to the hens. The first data of the experiment were recorded after one month of laying (25th week). These data allowed to determine the weight and size of the collected eggs. After 7 months of experience, results showed that supplementation of 2% and 4% soybean oil improved respectively the weight to 2.49 g and 1.36 g. For the size of the eggs, the incorporation of 2% and 4% soybean oil gives similar values but higher than those of the control lot (0%). Conclusions and application of the results: Soybean oil is therefore seen as a mean for improving the yield of poultry production. An application of the use of this oil in poultry feed would be an asset for the poultry sector and will improve the income of producers. Key words: egg laying feed, soybean oil, linoleic acid, eggs

Many fibrous ingredients incorporated in poultry feed to reduce production costs have low digestibility and cause poor growth in poultry. However, all plant-based fibers are not equal, and thus exert variable physiological effects on the birds, including but not limited to, digestibility, growth performance, and microbial fermentation. Several types of fibers, especially oligosaccharides, when supplemented in poultry diets in isolated form, exhibit prebiotic effects by enhancing beneficial gut microbiota, modulating gut immunity, boosting intestinal mucosal health, and increasing the production of short-chain fatty acids (SCFA) in the gut. Recently, poultry producers are also facing the challenge of limiting the use of antibiotic growth promoters (AGP) in poultry feed. In addition to other alternatives in use, exogenous non-starch polysaccharides digesting enzymes (NSPase) and prebiotics are being used to provide substrates to support the gut microbiome. We also conducted a meta-analysis of different studies conducted in similar experimental conditions to evaluate the variability and conclusiveness in effects of NSPase on growth performance of broilers fed fibrous ingredients. This review presents a holistic approach in discussing the existing challenges of incorporating high-fiber ingredients in poultry feed, as well as strategies to fully utilize the potential of such ingredients in improving feed efficiency and gut health of poultry.

Abstract High environmental temperature due to climate change can accelerate oxidation of feed during storage and preparation. Oxidized feed can cause elevated oxidative stress in live birds, resulting in decreased productivity and meat quality of broilers. The study was aimed to determine effects of feed containing oxidized oil on growth performance, plasma oxidative stress, and breast meat quality of broilers. Male broilers (192; Cobb500) at 21 days old were randomly allotted to 32 pens (8 pens/treatment) and raised for 21 days. The birds were fed feed containing fresh (Control) or oxidized corn oil (5%, Peroxide Value:140) with or without vitamin E (500 IU/kg feed) supplementation. Growth performance, oxidative stress markers in plasma collected at Day 42, and quality parameters of breast meat harvested at Day 43 were determined. Data were analyzed using proc glm and means were compared using Tukey’s studentized range (HSD) test. Oxidized feed and/or vitamin E supplementation did not affect growth performance and plasma DNA and protein oxidation. Oxidized feed significantly increased lipid oxidation and reduced total antioxidant capacity in plasma (P &lt; 0.05) and, interestingly, dietary vitamin E made them worse (P &lt; 0.05), indicating that oxidized lipids in feed can induce oxidative stress in live birds and vitamin E may act as a pro-oxidant in highly oxidized conditions. Although they did not affect sensory and functional properties of chicken breast meat, oxidized feed significantly increased lipid oxidation in cooked meat (P &lt; 0.05) but dietary vitamin E considerably inhibited its development (P &lt; 0.05), indicating that oxidized oil and vitamin E in feed can be accumulated in muscle and act as a pro- and anti-oxidants in meat, respectively. The results suggested that oxidized oil in feed can increase oxidative stress in live birds and susceptibility of breast meat to lipid oxidation, and dietary vitamin E can improve its oxidative stability.

The Cost

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.

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.
