World’s Poultry Congress 2020 Paris, France
The World’s Poultry Congress, 7-11 August 2022 in Paris, France, is WPSA’s most important meeting. Having been postponed for two years, the organization of the event is now well on track. Important dates include: 7 August, with the opening session that will include a celebration ceremony for the inductees into the International Poultry Hall of Fame, plus the announcement of the winners of WPSA’s Paul Siegel and Education Awards, and the winners of the Cliff Carpenter International essay competition. The 9th of August will include the Council Meeting for the membership, with its election of new WPSA Board officers and directors for the years 2022-2026 (who will conduct and oversee the operation of WPSA during those years), and the selection of the country and venue for the next World’s Poultry Congress that will be held in 2026. It is hoped that current hostilities and travel restrictions, will not prevent your participation in WPC 2022.
For more info on the World’s Poultry Congress please consult www.wpc2022.org.
The world is re-opening slowly for meetings and exhibitions. The Mediterranean Poultry Summit, 8-10 June in Cordoba, Spain, is the first meeting in June, 2022, followed by an International Symposium in Bangladesh and Pakistan. Next week, one of the largest in-person exhibitions, VIV Europe in Utrecht, The Netherlands, will stake place. WPSA will be present, and we also plan to be present at Victam Asia; at the Animal Nutrition and Health meeting in Bangkok, Thailand; as well as at the Poultry Africa meeting that will be held in Kigali, Rwanda. Please check wpsa.com for more details related to these meetings.

Treasurer's Report
I have a quick, but important reminder for all who plan to apply for WPSA Travel Grants. If you wish to have a competitive and accepted application, you must follow the very clear guidelines on the WPSA website. We transact all business in US dollars. When you are finding your low cost, economy air fare, click the Currency Button to ‘US$’, or if you are using a travel agent, instruct him/her that the quote must be in US$. You cannot get a quote in a foreign currency and then list your request in US$, without showing a conversion. The easiest method is to let the airline website and/or travel agent do the work for you.
If you do not have personal funds to cover a trip to a WPSA event, be FRUGAL in how you plan your trip expenses. Do not book a room at the most expensive host hotel! Do not ask for funds for daily lunch when it is already included in your registration fee.
Major professors and Branch secretaries: please carefully review all of the applications coming from your students and/or other Branch members. If the application has not followed the guidelines, it will not be accepted.
WPSA is dedicated to assisting members (especially students) attend WPSA conferences and congresses. However, it is very disheartening to us when poorly completed applications are submitted, and then have to be rejected.
I look forward to seeing you in Paris. I will be especially pleased to congratulate in person our successful Travel Grant recipients.

Evaluation of light emitting diode characteristics on growth performance of different poultry species: A review
O.M. OSO, K. METOWOGO, O.E. OKE and K. TONA
Agriculture and climate are highly interdependent. Light-emitting diode (LED) is a climate-2 friendly bulb that has been considered as a promising replacement for conventional lighting in 3 poultry production due to its efficient energy utilisation. Poultry responds to different light 4 characteristics such as source, intensity and wavelength. The review on the effect of LED bulb on 5 different species of poultry birds revealed that there is a knowledge gap on the effects of LED 6 bulbs characteristics on turkeys. Also, there is a dearth of information on the impact of LED on 7 ducks, geese and quails. However, studies on broiler production showed that the effect of LED 8 light on birds can be influenced by wavelength, correlated colour temperature (CCT), age, sex and 9 season of the year. LED bulbs can safely be used as a replacement for conventional lights since no 10 advert effect of LED light has been highlighted in the literature. It has generally been observed 11 that monochromatic green and blue light colour accelerate growth performance in broiler birds. 12 Green and blue colour mixing/switch at certain stages of production further boost the growth 13 performance compared to single colour lighting. The effect of light spectrum in poultry has not 14 been fully explored. Future researches can bridge the knowledge gap on the effect of ultraviolet 15 light spectrum on different poultry species and the use of poultry-specific LED adapted for avian 16 spectral sensitivity can be further researched.
Influence of LED bulb on reproductive and production performance of different poultry species: A review
O.M OSO, K. METOWOGO, O.E OKE and K. TONA
Light is the most critical factor in the poultry environment due to avian spectral sensitivity which greatly differs from that of humans. The review on the reproductive and production responses of poultry birds to LED reveals a paucity of information on ducks, geese and quails. Limited studies exist on the effect of LED on guinea fowl, turkeys and breeder birds. Reproduction in poultry birds appears to be more influenced by wavelength rather than other LED characteristics. Poultry birds are critically sensitive to wavelength. Red LED improves sperm quality in roosters and egg production in laying hens and quails without a significant impact on egg qualities while blue LED also appears to favour production in ducks. Studies are needed on how best shorter wavelength (ultraviolet light) can be maximized in poultry. Further research should focus more on making the scientific information available on the impact of LED on guinea fowl, turkeys and breeder birds.
A comparison of the various equations published for the estimation of characteristics of hen’s eggs, the importance of reporting the compression rate for shell strength measurements, and the distinction between specific gravity and density in relation to eggs
R.M.G. HAMILTON
Prediction equations allow the estimation of dependent variable from the value obtained from the measurements of an independent variable. Comparisons of estimates obtained for of 85 equations that were published for the prediction of shell strength parameters were made. Egg weight, specific gravity, length, width and thickness were the independent factors use to estimate surface area (SA), egg volume (EV), shell weight, percent shell, sphericity, thickness, compression and impact fracture strength, and shape index. Values (n = 5 to 20) from published results were used to create a data set for the testing of these equations.
Comparisons, based on coefficient of variation (CV), among the calculated estimates obtained with the majority of the equations (72) showed the variability was small, especially those for SA and EV, However, the CV for other equations (7) showed their estimates varied over wide range; whereas, the estimates for the remainder (6) were outside the expected acceptable range. Ten equations, as published, required an ‘adjustment factor’, either multiplication or division, in order to produce an estimate that was within the expected range.
It is essential that the rate of compression used to measure compression fracture strength of egg shell be reported because, since the egg shell is a brittle material, the value obtained when fracture strength is measured by compression is dependent on the compression rate. Without knowing the compression rate, it is not possible to establish whether the difference among published shell strength measurements is actual or due to differences in compression rates.
There is a need to clarify that the ‘saline flotation method’ measures the density of the egg, NOT specific gravity. Also, the use of various abbreviations for the same shell strength variable causes confusion that could be clarified by the development of standardized abbreviations. Finally, more care is needed to ensure the original authors are cited when reporting the sources of prediction equations.
A meta-analysis comparing the composition and quality differences between chicken meats produced under the free-range and conventional systems
P. DAVOODI, A. EHSANI, R. VAEZ TORSHIZI and A.A. MASOUDI
Inconsistent results about the effects of free-range and conventional systems on economic carcass characteristics and the chemical composition of chicken meat have been reported. Free-range chicken meat has been presumably known as more nutritious and healthier than conventionally meat products so it has become highly present in the marketplace. In this study, due to an extensive systematic review plus meta-analysis, the effect of conventional and free-range rearing systems on meat quality and carcass traits have been evaluated based on thirty-nine included studies. A high level of heterogeneity was seen among studies, therefore, statistical analyses of random-effect models have been conducted to calculate summary statistics for the standardized effect size of the difference between free-range and conventional rearing systems. As a result, free-range significantly influenced abdominal fat yield, meat yellowness, protein, and fat content of breast meat. However current meta-analysis showed that free-range had no significant negative effect on carcass weight, breast yield, leg yield, initial/ultimate pH, meat redness, cooking loss, drip loss, water holding capacity, and ash. In addition, two subset analyses according to sex (male, female, and both sexes) and comparison type (slow-growing, fast-growing) clarified a part of sources of heterogeneity. Eventually, this study reported conclusive results that free-range significantly increased meat-related traits typically yellowness and protein of breast meat and conversely decreased abdominal fat yield, and fat content of breast meat. In conclusion, free-range meat products can be characterized by different appearances due to the lower proportion of abdominal fat and yellower breast meat, also healthier and more nutritious because of lower fat concentration and higher protein content.
Nutritional and non-nutritional factors affecting egg yolk pigmentation
D. ZURAK, P. SLOVENEC, Z. JANJEČIĆ, D. BEDEKOVIĆ, J. PINTAR and K. KLJAK
The colour of the egg yolk is one of the most important sensory characteristics among consumers and is often perceived as a health and quality component of the product. Carotenoids found in hen diet are the main components contributing to the yolk pigmentation, and therefore, nutrition is a major factor influencing the yolk quality and colour. The ratio of yellow and red carotenoid pigments is of great importance in achieving the desired yolk colour. The difficulties associated with the optimum carotenoid concentration in the diet arise from the considerable variation in amounts in feeds and bioavailability from the sources used, synthetic or phytochemical. In addition, the carotenoid content in phytochemical sources is not always constant, and it is necessary to consider their interaction with other components in the diet, as well as denaturation during processing or loss during prolonged storage. Laying hens are unable to synthesise carotenoids de novo and depend on their supply through the diet. For this reason, pigmentation can decrease due to reduced diet intake, which a number of factors can influence. The housing system affects yolk pigmentation due to differences in applied nutritional management. In addition, reduced diet intake, carotenoid utilisation for health defence and reduced absorption occurs in response to stress conditions and various diseases. The objective of this review was to summarise the recent findings in available literature data on nutritional and non-nutritional factors affecting egg yolk pigmentation.
Guajolote – A poultry genetic resource native to Mexico
R. PORTILLO-SALGADO, J.G. HERRERA HARO, J. BAUTISTA-ORTEGA, A.J. CHAY-CANUL and F.A. CIGARROA VÁZQUEZ
The Guajolote is a native North American poultry, originally domesticated in Mexico, from where it was exported to Europe, and from there to the rest of the world, becoming the genetic base of the breeds and varieties of turkeys that are known in the present. However, the phenotypic and productive characteristics of Guajolotes have been poorly studied, which has limited its racial recognition. This review describes the current knowledge on the historical distribution, morphological, morphometric, and phaneroptic characteristics of Guajolotes, as well as the productive performance and quality attributes of Guajolote meat and eggs. Due to the long process of evolution, Guajolotes have a good capacity for adaptation and high rusticity that allows it to reproduce under different environmental and management conditions. It has unique morphological peculiarities and great variability in terms of its morphometric and phaneroptic descriptors. This bird has a marked sexual dimorphism in favour of males. Females are excellent natural incubators, they start laying from between 6 and 8 months of age, laying an average of 16.7 ± 3.6 eggs per laying season. Males have a good capacity to convert food into meat and can reach a live weight of between 5499 ± 148 to 5835 ± 173 g at week 30 of age, having a carcass yield of 79%. The nutritional quality of meat and eggs of Guajolote is even higher than that of chicken. In conclusion, Guajolotes are poultry with characteristics of high biological and productive value; however, better management strategies are required to maximize its genetic potential for the benefit of the food security of small and mid-size producers that depend on this poultry genetic resource.
Signature of Indian native chicken breeds: A perspective
M. KANAKACHARI, H. RAHMAN, R.N. CHATTERJEE and T.K. BHATTACHARYA
Native chicken in India assumes a significant role in contemplating rural economy. The local birds play major role in providing subsidiary income and nutritional security to the people of India. A total of 19 native chicken breeds have been reported and registered in India by ICAR-National Bureau of Animal Genetic Resources, Karnal, India, which is the nodal agency of Government of India for registering breeds of livestock and poultry. At present, the Indian native chicken population is 37.2% of the total poultry population, which contribute around 17.8% of the total egg production in the country. The Indian birds have many unique traits such as natural broodiness to hatch chicks, better adaptability to hot and humid tropical climate, resilience to some of the deadly diseases such as Newcastle disease, IBD etc., black coloured meat of Kadaknath chicken, running fast and flying, fighting habit to protect themselves from the predators, tenderness of meat similar to red meat, low mortality at high temperature and humidity when exotic birds mostly die, survival on scavenging and perform at low input diet. The major objective of this paper is to compile the characteristics of Indian native chicken breeds comprehensively so that by going through this article, the stakeholders may categorize any birds of India in a particular indigenous breed group or any other group or non-descript groups. In this article, we reviewed signature of Indian chickens to differentiate them from the exotic and other breeds of chicken. We have delineated phenotypes and molecular parameters of Indian chickens along with their performances. We have deciphered genetic distance of some of the Indian chickens from the exotic chickens revealing their unique position in the cluster. It is concluded that the breed signature has potential to distinguish Indian chicken population from exotic ones for the breed identity.
Impact of chitosan on productive and physiological performance and gut health of poultry
S.S. ELNESR, H.A.M. ELWAN, M.I. EL SABRY, A.M. SHEHATA and M. ALAGAWANY
The general trend in the poultry industry considers animal welfare and the quality of final products. The prevalence of antibiotic resistance, along with increased public concern about superbugs, resulted in considerable interest in the use of natural and safe alternatives in poultry production to lessen the risk of resistance transfer to humans via the food chain. Some feed additives such as chitosan may confer additional cytoprotective impacts. Chitosan is a biosynthetic polysaccharide that is the deacylated derivative of chitin. Chitosan is one of the promising natural polymers and additives that has attracted great attention due to its biological properties such as biocompatibility, biodegradability, antioxidant, antimicrobial, non-toxicity and anti-inflammatory activity. Chitosan has been shown in recent publications to be an effective feed additive for poultry health and an antibiotic growth promoter alternative. Thus, it can be concluded that chitosan is one of the natural feed supplements expected to enhance the overall health and productivity of different poultry species. This review contributes to updating our knowledge on producing chitosan, its characteristics, and dietary chitosan influences on the productive performance and gut health of poultry.
The role of early feeding in improving performance and health of poultry: herbs and their derivatives
M.A. ARAIN, F. NABI, Q.A. SHAH, M. ALAGAWANY, S.A. FAZLANI, M. KHALID, F. SOOMRO, F.M. KHAND and M.R. FARAG
The key objective of poultry husbandry is to provide safe and nutritious food for the growing population. The technique of delivering various nutrients, nutraceuticals, vaccines, immunostimulants, phytochemicals and medicinal herbs via the in ovo route is gaining wide attention among scientists worldwide for improving poultry productivity, boosting immune response and safeguarding the health. Embryonic growth in poultry has been manipulated through direct administration of biological compounds into embryonated eggs during the mid and late phase of incubation. This shows potential to enhance hatchability, superior nutritional status, higher chick quality, improve post-hatch performance and ultimately reduce the challenges associated with infections and oxidative stress, as well as minimize the use of synthetic antibiotic growth promoters in poultry production. In the last two decades, several studies have demonstrated that the in ovo supplementation of herbs and their derivatives such as chicoric acid, rosmarinic acid, astragalus polysaccharides boost immunity, upregulates antioxidant defence, and improves the health status and production output of poultry birds, making herbal compounds an alternative to antibiotic growth promoters. In ovo injection of herbs and their phytochemicals has shown diverse advantages, including improvements in weight gain, feed efficiency, growth rate, decreased morbidity and mortality of embryos, boosted immunity, and improved health status of poultry birds. Furthermore, in ovo injection of herbal compounds has shown better protection against a number of infectious pathogens than post-hatch supplementation. The current review aimed to provide a promising insight for the promotion of in ovo technology in order to supply natural biological compounds/phytochemicals directly into the developing embryo to achieve an improvement in post-hatch growth, immune responses, antioxidant defence and highlights the future of in ovo technology as a strategy to minimize the use of AGPs and improve the health status and production performance of poultry.
Current status of dietary Moringa oleifera and its application in poultry nutrition
NORHIDAYAH MOHD TAUFEK, SITI NUR NABILA ZAINOL ARIFFIN, NORHAFIZA MOHD ARSHAD and MOHD SHAHMI HAKIMI MAZLISHAH
The increasing demand for poultry products has driven the utilisation of more conventional crops as poultry feed. To achieve economically viable and environmentally friendly poultry production, attempts have been employed to incorporate medicinal plants such as Moringa oleifera in their diet. The high nutritional factor, including high protein content, the abundance of micronutrients and various phytochemicals has contributed to the rapid use of M. oleifera in the poultry diet. Notably, its application has a significant impact on poultry health and husbandry. The following paper reviews M. oleifera on their efficacy, potential limitation and effect on target poultry species. Furthermore, recognising the impact of utilising different processing methods on this plant could offer poultry and feed producers considerable benefits.
Nutrigenomics and nutrigenetics in poultry nutrition: An updated review
M. ALAGAWANY, S.S. ELNESR, M.R. FARAG, K. EL-NAGGAR and M. MADKOUR
Nutrition has long been recognized to cause metabolic changes in muscles, such as tissue remodelling, increased protein turnover, and muscular atrophy. From a production standpoint, these modifications have an impact on production efficiency and meat quality. As a result, they are extremely valuable economically. Nutritional constraints related to specific dietary components and management measures can be difficult to determine quickly. Nutritional Genomics describes the nutrient-gene interactions, as it includes two areas; nutrigenomics and nutrigenetics. The term ‘nutrigenomics’ refers to the study of the effects of nutrients/bioactive foods on an individual's gene expression. In the other hand, nutrigenetics describes that the genetic profile has impact on the response of body to bioactive food components by influencing their absorption, metabolism, and site of action. The inclusion of nutrients and nutraceuticals in poultry production can enhance gene expression of different genes related to health, metabolism, growth, immunity, and antioxidants. This review aims to shed the light on the definition of nutrigenomics and nutrigenetics in poultry nutrition.
