In addition, a low protein diet supplemented with essential amino acids was found to be useful tool to maintain performance and immunity of chickens when other nutrients were met (7375). Global poultry farming has aggressively selected for traits that focus on maximum poultry production and improving feed utilization and farming profits. Data on the effect of dietary fiber have been gaining importance due to the use of grains for ethanol production and the search for feed alternatives that could help in sustainable and cost-effective broiler production. This strategy included improving the educational background of workers through continuing education and training programs, improving biosecurity and hygienic measurements for poultrymen, slaughterhouses, and feed plants, and in farm biosecurity and hygiene. Recently, Moawad et al. (2016) 44:8798. Eur Poult Sci. It is used to sustain physiological function, immunity, health, and product quality (97101). Zn homeostasis is closely connected with the normal operating of both eukaryotic and prokaryotic cells, and thus many pathogens are indirectly or directly influenced by perturbations in Zn homeostasis. Pak Vet J. It should be prospective and incorporate emerging zoonotic diseases that may require new vaccines for their control.

Rahman M, Amin R, Mst IRB, Fries R, Husna A, et al. Disease control is the key element for improving animal production and food safety and, thus, human well-being. Poultry, defined as domesticated birds kept either because of their meat, feathers or eggs, constitute a fascinating and diverse group of animals, which can be integrated into many farming systems throughout the world for the mutual benefit of animals and the humans involved. Coronavirus disease 2019 (COVID-19) pandemic, lessons to be learned! Professional egg producers can increase the output of laying hens to nearly 300 eggs per year, twice the average during the middle of the 20th century. Additionally, studying the biological methods and genes responsible for conveying inherent resistance to different infections will lead to enhanced vaccination response to different viral and bacterial disease and/or establish disease-resistant poultry flocks (44, 55). Nat Immunol. (2007) 86:23240. doi: 10.3382/ps/pew186, 133. It also considers the economic, social, and ethical concerns, as well as the methods required to accomplish a high level of hygiene and safeguard the environment (31, 35). Smallholder poultry production has an important role to play in feeding the world and, to maximise the benefits, it should be accompanied by improvements to local health services and holistic programs that highlight the links between poultry production, human health and nutrition and sustainable ecosystem services. doi: 10.1177/1040638712463692. A prevention strategy to control the spread of COVID-19 is a lockdown, blocking transmission pathways, and educating the public to increase their awareness of the disease and decrease trade activities (40). Beneficial microbiota can also help maintain animal health (87, 88). The World Health Organization (WHO) and the Food and Agriculture Organization (FAO) risk assessment definitions encompass the scientific assessment of potential adverse health and known negative effects. An important part of raising chickens is feeding - feeding makes up the major cost of production and good nutrition is reflected in the bird's performance and its products. Ital J Anim Sci. Yausheva E, Miroshnikov S, Sizova E. Intestinal microbiome of broiler chickens after use of nanoparticles and metal salts. The Mineral Nutrition of Livestock. doi: 10.3382/ps/pez573, 70. Hence, meeting per capita consumption and welfare to humans necessitates continuous efficient and goal-oriented healthcare to control disease spread and decrease the application of antibiotics (1). Besides, useful education programs should be employed to markedly raise public awareness about the essential measurements required to safeguard against zoonotic diseases (54). Sci. Birds may have the required daily feed intake, but are we ensuring that their distribution provides a completely balanced diet. Why are new antibiotics not being marketed? World Poult Sci J. In a future study, improvements in laboratory diagnosis will offer sensitive, fast, and precise disease diagnosis, and early mediations will be a reality (4547). Korish MM, Attia YA. The bursa of Fabricius is divided into follicles; it is occupied with B lymphocytes that produce specific antibodies, which circulate in the bloodstream. 2. The improved immunity of broilers supplemented with canola oil concurred with an increased villus height-to-depth ratio. If you are still at the planning stage, it is worthwhile to get familiar with best poultry management practices and have a clear idea whether your priority is egg production or raising chickens for meat. Increase the self-sufficiency ratio of broiler chickens by 4260%; 2. Recent advances in poultry nutrition have focused on three main areas: Practical poultry diets are formulated from a mixture of ingredients, including cereal grains, cereal by-products, fats, plant protein sources, vitamin and mineral supplements, crystalline amino acids and feed additives.

However, perhaps the most important lessons are the need to boost natural immunity as the first line of defense and that the health of the world must be considered as one unit that cannot easily be disentangled. National Research Council (NRC). Attia YA, Bovera F, Abd-El-Hamid EA, Tag EL-Din AE, Al-Harthi M A, Nizza A, et al. It also assists in the synthesis of body tissue, for that renovation and growth of the body. doi: 10.1093/ps/86.2.232, 33. Applying an inefficient feeding strategy can have negative implications on long-term results and the birds ability to cope with field challenges. also influenced by the housing system and, to the extent that we consider alternative systems, where they express natural behavior patterns such as digging-foraging (often misdirected) and increased movement. More information on this topic, as well as detailed advice on meeting HACCP standards, is available. Antibiotic tolerance in humans and animals (especially bacteria) is now a common topic, and it is expected to be a continuous public health hazard (12, 13). Coconut fat ameliorates broiler digestion of lipid and raised productive performance during the course of coccidiosis infection (82). The mucosae comprise several defined lymphoid tissues that reply exactly to the used antigens, and this immune reaction can be either humoral or cellular (138140). (2020) 6:510. doi: 10.3389/fvets.2020.00436, 74. Lymphocyte, splenocyte, and heterophil proliferation, maturation, and cytokine production are affected by omega fatty acids. The objective is to obtain a correct corporal development, uniformity and to promote the intestinal health of the birds that will be key for the future of the flock. Infectious diseases and health disorders are mostly connected to negative economic impacts. Using crystalline amino acids to supplement broiler chicken requirements in reduced protein diets. The main functions of selenoproteins are control of redox of biochemical function, antioxidant balance systems, thyroid hormone anabolism and catabolism (106), anticancer protection (108), and immune function booster (117, 118). 17:115. (13, 124126) concluded that vitamins E and C have a great effect on productive performance and immune response of animals exposed to heat stress. Omega-3 and omega-6 fatty acids in poultry nutrition: effect on production performance and health. Gut Pathog. (2020) 92:47990. Hence, future strategic plans are required to decrease contamination of chickens before their dispatch to processing plants and to ensure there is an adequate focus on the reduction in the availability of feed ingredients for animal feeds in view of the COVID-19 pandemic's effects on the food chain and feed industry around the world. Curr Opin Biotechnol. Heritage breeds are those raised by our farming ancestors. (2019) 103:95968. Van den Berg T, Lambrecht B, Marche S, Steensels M, Van Borm, et al. (2003) 61:25667.

The use of nano-minerals in trace mineral nutrition increases their bioavailability, decreases antagonism between minerals at intestinal sites, and reduces excretion and, hence, trace-minerals related pollution. Evolution of productive capacity in LB Classic and LSL Classic. Br J Nutr. Some important findings include the following: In addition, the public health hazards from consuming foods with high antibiotic residues will remain a critical issue. Attia YA, Hamed RS, Bovera F, Abd El-Hamid AE, Al-Harthi MA, Shahba HA. Compared to the countries with the highest meat and egg production countries, Saudi Arabia imports most of the broiler meat its citizens consume, with production accounting for less than 58% of the consumed meat (4). The tolerance to metronidazole, sulfamethoxazole/trimethoprim, nalidixic acid, ciprofloxacin, and tetracycline was 58 (76.3%), 58 (76.3%), 51 (67.1%), 53 (69.7%), and 42 (55.3%), respectively. Inert digestibility index markers such as titanium dioxide are universally accepted to provide simple measurement of digestive tract retention and relative digestibility in poultry feeding trials. The emerging disease should give maximum attention. The research and development in poultry disease identification and control should not be limited to currently known diseases. (103) found that the degree of cutaneous hypersensitivity to phytohemagglutinin (PHA) at 21 and 35 days of age was greater in broilers given organic Fe, and Gumboro antibody titers at 35 days of age are increased in broilers offered iron chelator, but at 42 days of age, the differences are diminished among broilers. Baby fowl need proper environment, nutrition and protection. Improve the innate animal immunity as the frontline of disease prevention and control. doi: 10.3923/ijp.2017.907.915, 105. More countries must be able to achieve self-sufficiency in production, an endeavor that requires increased investment after the COVID-19 pandemic ends. The health of animals is mediated by immunity and the risk of infection and invading pathogens. Dietary fish oil markedly increases antibody titers and the relative spleen and bursa weights compared to the control group (81). The effect of Zn on chickens' immunity is also well-documented in the literature (112). In order to control the recent outbreak, a global strategy must be developed and applied worldwide. Potential interventions for novel coronavirus in China: a systematic review. Front. The technical storage or access is required to create user profiles to send advertising, or to track the user on a website or across several websites for similar marketing purposes. Immunity is the frontline of defense and birds have several non-specific defense mechanisms such as intact skin and cilia in the respiratory system, as well as the low pH and intestinal flora in the gut system (4850). We often talk about the composition and homogeneity of feed, ignoring the influence it has on: We must provide them with a nutritionally balanced feed and an effective feeding program that meets their requirements . doi: 10.5455/javar.2020.g412. Occasionally, nutritional deficiencies can trigger undesirable behaviors, manifesting even during the rearing phase. 99.

(1996) 75:87580. There is no proof for either horizontal or vertical transmission from one flock to another with regard to a known poultry house contamination. They enable cycling of nutrients through feed, manure, and soil. (2017) 223:4252. (111) revealed that substituting FeSO4 with iron-glycine chelate at the identical dietary Fe concentration cannot enhance the broilers' productive criteria. These benefits are critical for broilers and laying hens to prevent cage layer fatigue and poor eggshell quality (100102). 8. 6. Front Immunol. This section also contains information on water quality, disinfection steps, water tanks, and water lines. Jameel YJ, Sahib AM, Husain MA. However, this use may increase the threat of antibiotic-resistant bacteria and the negative impact of antibiotics on the environment, such as cross-resistance and carryover influences. (2003) 4:83542. This goal is achieved by supplementation with industrial amino acids such as methionine, lysine, arginine, tryptophan, and threonine to ensure adequate intake of limiting essential amino acids (6870). Essential fatty acids, principally n-3 polyunsaturated fatty acids, are essential for human and animal health and immunity. Detection of Avian coronavirus infectious bronchitis virus type QX infection in Switzerland.

However, adaptive immunity is also implicated in allergic responses and for the rejection of transplanted tissue, which may be considered a harmful foreign invader (53). doi: 10.1002/jmv.25707, 63. Use of anticoccidial medications and vaccines in poultry production. Generally, vaccination does not prevent infection; rather, it only leads to a reduction in the number of outbreaks. (2019) 12:42433. In addition, avian influenza and Newcastle disease antibody titers were sustainably increased due to enriching a broiler diet with 1.5% coconut fat. Finally, rural impact, economic effects, and bio-diversity are also considered. The productive potential of the bird is the same regardless of the system that we consider, although the alternative systems require more attention since there are more factors that influence productivity compared to cage systems. Vitamin D supplementation of initially vitamin D-deficient mice diminishes lung inflammation with limited effects on pulmonary epithelial integrity. (2000) 79:9941004. Front Immunol.
