Toll like receptors and cytokines as immunostimulatory adjuvants in poultry vaccines: current status and future trends
S. BHADOURIYA, B.K. SHARMA, N.K. KAKKER and R. CHHABRA
In the face of reducing reliance on in-feed antibiotics, a greater emphasis has been placed on the development of vaccines. Adjuvants play important role in vaccine refinement. Apart from conventional adjuvants, others, like cytokines and toll-like receptors (TLR), have been evaluated experimentally. For example, Pam3CSK4, Polyinosinic-polycytidylic acid are used as immunostimulatory agents which upregulate the expression of type 1 IFNs against avian influenza. The use of TLR4 (lipopolysaccharide; LPS), TLR7 (Loxoribine) and TLR21 (CpG-ODN) agonists have shown good results when used as adjuvants with the avian influenza vaccine. The LPS (TLR4) was used as an adjuvant and liposome as intranasal antigen delivery system for Newcastle’s disease (NDV) antigen, which induced significant increases in secretary IgA in tracheal lavage fluid and serum IgG levels. In a challenge study it provided 80% protection against virulent challenge. When resiquimod (TLR7) was used as an adjuvant with inactivated NDV, this potentiated the protective response to 100% against virulent NDV challenge, while protection was only 80% in the vaccine alone group. When 64CpG-plasmids (TLR21) were co-administered with inactivated AIV H5N2 vaccine in chickens, it led to a higher HI titre at two and four weeks of age, and provided 100% protection against virulent challenge of avian influenza. The TLR 3 agonist (poly I:C) showed good results against NDV and avian reovirus. Other TLR agonists and cytokines used against NDV include LPS, loxoribine, CpG-ODN and ChIFN-α, IFN- γ (with an in ovo vaccine). Immunostimulatory adjuvants like LPS, chicken TLR21, have been tried with Marek’s disease vaccine, and TLR 5 agonist was used against Salmonella enteritidis and Eimeria tenella. Although the study of cytokines and TLRs in avian species is still in its infancy when compared to that of mammals, huge strides have been made in recent years. In this article, recent studies involving the assessment of immunostimulatory adjuvants in poultry are reviewed.
Machine learning application in growth and health prediction of broiler chickens
B. MILOSEVIC, S. CIRIC, N. LALIC, V. MILANOVIC, Z. SAVIC, I. OMEROVIC, V. DOSKOVIC, S. DJORDJEVIC and L. ANDJUSIC
Artificial intelligence (AI) already represents a factor for increasing efficiency and productivity in many sectors, and there is a need for expanding its implementation in animal science. There is a growing demand for the development and use of smart devices at the farm level, which would generate enough data, which increases the potential for AI using machine learning algorithms and real-time analysis. Machine learning (ML) is a category of algorithm that allows software to become accurate in predicting outcomes without being explicitly programmed. The essential principle of machine learning is to construct algorithms that can receive input data and use statistical analysis to predict an output. Exploitation of machine learning approaches, by using different training inputs, derived the prediction accuracy of growth and body weight in broiler chickens that ranged from 98 to 99%. Furthermore, a neural network with an accuracy of 100% identified the presence or absence of ascites in broiler chickens, while the support vector machine (SVM) model obtained an accuracy rate of 99.5% in combination with machine vision for the recognition of healthy and bird flu-challenged chickens. Consequently, machine learning algorithms, besides accurate growth prediction of broiler chickens, can successfully contribute to health disorders prediction. It is obvious that machine learning has a great potential for application in the future. This paper analyses machine learning applications in broiler growth and health prediction, and its ability to cope with high inputs of data and non-linearity can successfully replace common methodology.
Does magnetised drinking water influence poultry’s health and production?
K. EL-SABROUT and A. EL-HANOUN
Water makes up over 98% of all molecules in the body and it is necessary for several biological processes. Water quality has been shown to influence animal’s performance. In recent years, interest in water treatment technology has increased, particularly in poultry. Magnetised water is one of water treatment that has attracted poultry researchers and breeders, due to its low cost compared to chemical and physical water treatments. Water magnetisation changes water properties, making it become more fluid, alkaline and energised. Unfortunately, the information detailed in the literature provides opposite views on the effect of magnetised water on poultry’s performance. However, magnetised water, particularly with high gauss (more than 1000 gauss/month) could improve health (immunity), growth (approximately +4 % in weight) for broilers and enhance some egg production traits for hens, such as eggshell thickness (approximately +9 %). This review provides information detailed in the existing literature on the influence of magnetised water on poultry health and production.
When pain and stress interact: looking at stress-induced analgesia and hyperalgesia in birds
B.I. BAKER, K.L. MACHIN and K. SCHWEAN-LARDNER
Stress can exert modulatory effects on pain perception in animals, as exposure to a stressor can result in either the reduction or amplification of the perceived severity of pain. These phenomena are widely described as stress-induced analgesia (SIA) and stress-induced hyperalgesia (SIH). The two are mediated by the same underlying mechanisms, but occur due to different stressors and different responses from the pain pathway. SIA and SIH have been demonstrated with a variety of stress and pain stimuli in rodents, humans and other mammals. There is some evidence that SIA occurs in birds and that they have the neurological systems and brain regions necessary for SIH. Tonic immobility (TI) is related to SIA in mammals, and there is evidence avian brain is compatible with TI having analgesic effect, but it could have a hyperalgesic effect. This review looks at the mechanisms and evidence of SIA, SIH and TI in mammals and discusses evidence relating to the occurrence of these phenomena in birds.
The role, importance and toxicity of arsenic in poultry nutrition
M. ŽIVKOV BALOŠ, S. JAKŠIĆ and D. LJUBOJEVIĆ
Arsenic (As) is highly toxic element, even at very low concentrations in feed and drinking water. Its physiological role in poultry is well established, as it is essential for the synthesis of methionine metabolites including cysteine, even though it is a teratogenic and carcinogenic element. Paradoxically, recent studies have uncovered its nutritional value. The recommended amounts of As in poultry feed are between 0.012 and 0.050 mg/kg. Water is the primary route for the transfer of As and exposure of animals to its toxic effects. The available data on the impact of water contamination on the deposition of As in broiler tissues are rather scarce. The amount of As was 0.006-0.015 mg/kg in breast meat, 0.007-0.017 mg/kg in drumstick meat, 0.001-0.014 mg/kg in liver and 0.008-0.016 mg/kg in testicles of broilers at the end of a 42 day experiment after exposure to naturally contaminated drinking water. The toxic dose of As for poultry is between 40 and 50 mg/kg of poultry feed whereas the amount of 40 mg/kg leads to decreased egg production and the amount of 50 mg/kg leads to decreased feed consumption. Symptoms of chronic As exposure differ among individuals, populations and geographic regions, which suggests that there is no universal definition of symptoms associated with chronic As poisoning. Moreover, some individuals can tolerate high As, that is, levels that can be fatal for others. In wild birds, the content of As was the highest in meat of march hens (0.063 mg/kg), seagull muscle tissue (0.058 mg/kg), in meat from swans (0.022 mg/kg) and the white-tailed eagle (0.022 mg/kg). In this review, the essential role and toxicity of As in poultry nutrition is addressed with particular emphasis on its importance as a contaminant of poultry feed and products.
Slow-growing male chickens fit poultry production systems with outdoor access
E. FAUSTIN EVARIS, L. SARMIENTO FRANCO and C. SANDOVAL CASTRO
Slow-growing, male chickens have been found to be a nutritious protein source with 24.73% protein in breast muscle. They have an acceptable carcass quality with at least 20% less abdominal fat, 3% more breast yield, and 3% more thigh yield than the birds raised in confinement. Similarly, slow-growing male chickens grown with outdoor access have a good bone quality with femur weight, length and diameter (16.5 g, 96.7 mm, and 8.61 mm, respectively). Considering fatty acid profile as a meat quality trait, breast muscles of slow-growing birds grown with outdoor access compared to those without such access have significantly higher polyunsaturated fatty acids level (3.85 vs. 3.36%), lower n6:n3 PUFA ratio (7.8 vs. 9.22) and lower saturated fatty acids content (26.29 vs. 28.73%). Raising slow-growing male chickens in production system with outdoor access has been confirmed to be beneficial for the animals, the producers, the consumers and the environment.
