Treasurer's Report

bradley francine new

Ah, it’s a new year and there are new record books. Faithful Branch Treasurers, I have many blank pages waiting for me to record your payments of Branch dues! The records in the 2018 record books have been compiled and forwarded to our Certified Public Accountant (CPA). Dr Mulder has also compiled the records from the Dutch accounts and those too are going in to our CPA.

It has been my pleasure to be working with some of our Latin American Branch officers. They have some exciting programmes planned for 2019, and are working to make good use of all the WPSA resources. Congratulations to our Branches in Africa and Europe who had their Speakers' Bureau and Branch Development applications approved for events happening this spring and early summer.

In mid-February I joined fellow Executive Committee (EC) Members (Drs. Mulder, Yang, and Buresh) at the International Poultry Production Exposition (IPPE) in Atlanta. We had a very productive EC meeting and started plans for this summer's Board Meeting. WPSA had a booth in Hall C at IPPE. It was an excellent opportunity to explain our organization to visitors and to greet members. Many of those individuals had travelled from around the world and included WPSA officers and members from Bolivia, Ghana, New Zealand, and many other countries.

As we look at the final page of the 2018 calendar, I send my wishes to all of you that you end the year in good health and remain active in your local Branches throughout 2019.

Dr Francine Bradley, Treasurer

Henk Hupkes

Henk Hupkes, 6 June 1947 - 25 November 2018

hupkes henk cropOn Sunday November 25, 2018 the Dutch branch of the WPSA lost her charismatic member Henk Hupkes. Henk started his poultry career at Meyn Food Processing Technology B.V. in 1982: his graduation in Mechanical Engineering from the Technical University Delft provided a good basis for his diverse tasks. Henk provided an indispensable bridge between a poultry processing equipment manufacturer and the scientific world. In 1982 became member of WPSA NL and he was member of the Board of WPSA NL from 1986 to 1992. He was member of the organizing committee of the successful WPC 1992 in Amsterdam, after which he became member and secretary of the Board of the Foundation for Promoting Poultry Science until his death in November 2018. From 1982 to 2010 he attended about all WPC’s and EPC’s, as well as the symposia of Working Group 5 (Poultry Meat). In all cases his presence was undeniable due to his eagerness to learn, his friendly and optimistic attitude, and his laughter. Since 2015 Henk suffered from cancer, a battle he couldn’t win. He finally lost the battle at the age of 71 years. Henk is badly missed by his loved ones and his many friends inside and outside the W PSA. He is remembered with respect, warmth and gratitude.

Jim McNab

Jim McNab, 5 April 1940 – 1 January 2019

mcnab cropIt is with great sadness that I have to announce the death of Dr Jim McNab, who died suddenly on January 1st. He was born in Comrie, Perthshire to Mary and Donald, in April 1940, and was much loved by his parents and his sister Mary. 
Jim excelled in school, at Morrison’s Academy in Crieff. Outside studies he played for the school’s 1st rugby team and enjoyed playing the clarinet. He was also an ‘extra’ in the 1953 film ‘Johnny on the Run’. 
From 1958 to 1965, Jim attended the University of Edinburgh with great enthusiasm and enjoyment. According to his good friend Dennis, academic issues were never a problem. After graduating with an Honours Degree in Chemistry he moved on to do his PhD in 1962, adopting three ‘Objectives’, the same ones most Graduate students pursued in the 1960s, namely a PhD in three years, a post-doctoral appointment in North America and finding the love of one’s life. He achieved the last of these when he met Carol during the first month of his PhD. He duly graduated in 1965 and set out for Boulder, Colorado, returning briefly for his marriage with Carol in October 1966. After a year in Colorado, they returned home and Jim spent a year back at Edinburgh University before he joined the Nutrition Department at the Poultry Research Centre (PRC) in Edinburgh in October 1968. His research covered many aspects of poultry nutrition, including the digestion of carbohydrate and protein and developing methods for feedstuffs evaluation. He studied feed quality enhancement and assessments of non-traditional feeds. 
In 1993, Jim became the head of the large Department of Nutritional and Environmental Studies at Roslin Institute, the successor to PRC. The work of his department included behaviour, welfare and other environmental topics, as well as nutrition. He gave good leadership to this widely-based department and battled hard at senior staff meetings at the Institute where the essentially applied nature of his department’s work was regarded somewhat less favourably than some of the seemingly more exotic sciences carried out in others.
Owing to increasing pressure on government research funding, the idea of expanding commercial income from aspects of Jim’s research was proposed, including his methods for feedstuff evaluation assays. In 1997, Roslin Nutrition, a spin-out company from Roslin Institute, was born. Jim and Doug Currie were charged with managing the company, which in 2002 became a completely independent research company, which is still thriving today.
Jim was a well-known and popular figure in the poultry nutrition world and a regular speaker at industry and scientific conferences. His other activities at work included responsibility for many national and some international projects, supervising numerous PhD students, co-editing British Poultry Science for 10 years and, for a shorter period, editing World’s Poultry Science Journal. He was very active in the UK branch, organising symposia and conferences. Jim retired from the Roslin Institute in 2001 and from Roslin Nutrition in 2005.
Outside work, Jim enjoyed playing rugby, squash and bridge. He was a keen vegetable gardener and latterly an enthusiastic cook. He was a proud and loving father to his two sons, Donald and Scott and he adored his four grandchildren
When his wife Carol was asked for her thoughts she said: Jim is remembered as having a great sense of humour: being reliable, generous, loving; positive, honest and forthright; a good man, a great dad; an intellectual, wise, clever man; a kind patient and a wonderful person.
On a personal note, Jim was a mentor during my PhD, training me in various ME measurements and becoming a good friend, as well as being a previous editor of WPSJ. He is survived by his wife Carol and his children and grandchildren. I would like to thank Carol for her great help with preparing his obituary. Our thoughts are with the family at this difficult time.

Keel bone injury in laying hens: the prevalence of injuries in relation to different housing systems, implications, and potential solutions


Increased pressure on the poultry industry by animal-rights organisations and environmentally-conscious consumers has led to the rising popularity of cage-free housing system for hens. One of the main dangers of cage-free housing systems is the possibility for laying hens to damage their keels. Keel bone fracture incidence rate ranges up to 85%, and can lead to extensive pain in any bird, and potentially be the cause of the death for a hen in a cage-free environment. It was reported that kneel bone damage observed in flocks housed in non-cage systems was 30 to 95% while in furnished cages it was 15 to 55%. The purpose of this review is to compare the prevalence of the problem found in the three main housing systems (conventional, enriched cage, and cage-free), discuss if such damage could affect the behaviour and production of laying hens, and provide potential solutions for reducing the prevalence of keel bone damage. Keel fractures can negatively affect a hen in its day-to-day life by causing pain and restricting its movements. The prevalence of keel bone damage varies considerably among the studies due to differences in the system design, genetic line, age and method for determining the keel damage, which makes difficult to compare the systems. The genetic selection, adequate nutrition and modifications in the house design have shown to be useful tools in reducing keel bone damage in laying hens.

Methionine: comparing methionine hydroxyl analogues for broilers, with focus on different thermal environments


Supplementation of methionine (Met) in broiler chicken diets is essential to support productive performance and optimise carcass yield. Met is the first limiting amino acid in corn and soybean-meal based diets for poultry. The DL-Met form is the main source used in broiler diets, but other sources such as acid free hydroxy-analogous methionine (HMA-FA) are available. Studies have indicated that the molar bioequivalence of HMA-FA is approximately 88% compared with DL-Met at 99% for growth traits. However, differences in absorption and metabolism between Met sources can influence their efficacy, especially when broilers are exposed to high temperatures. The substitution of DL-Met by HMA-FA is a potential strategy to mitigate the negative effects of heat stress because it is passively absorbed in the upper portion of the gastrointestinal tract. This review highlights the effects of substituting HMA-FA for DL-Met in diets for broiler chickens reared in different thermal environments.

The application of the microalgae Chlorella spp. as a supplement in broiler feed


Chlorella (vulgaris spp.; CLV) is a genus of unicellular freshwater microalgae that are fit for human consumption and are used as additives with high nutritional value in feed for agriculturally important animals. Chlorella spp. are characterised by their simple cultivation, high productivity and levels of protein and other nutrients. Investigations have shown that the growth performance of broilers can be positively affected by the addition of very low amounts of CLV biomass (0.5-1.0% of the diet) to feed. The effect of CLV on growth and development is considered to stem from its high protein content (60.6%) and nutritional value. Results have shown enhanced body weight gain (2.7%), better feed conversion ratio (lowered by 2.8%), meat colour and breast muscle weight (20.1%) in CLV-supplemented chicks compared to control birds (control breast weight 19.1%). Additionally, a significant decrease in drip loss (2.26%) from breast muscle was observed with CLV supplementation and levels of blood total protein, albumin, and high-density lipoprotein (HDL) cholesterol significantly increased (P<0.05), while the levels of liver enzymes indicative of oxidative damage (alanine aminotransferase, ALT) decreased by 23.2%, indicating better liver function. In terms of immunity, blood lymphocytes were increased in broilers fed a diet supplemented with liquid CLV (17.9 x 103/µl) compared with birds supplemented with dry CLV (13.5 x 103/µl). Additionally, the levels of IgA, IgG, and IgM were elevated by 29.7%, 69.1%, and 32.3%, respectively, in broilers that consumed feed containing CLV. Similarly, the intestinal diversity and abundance of Lactobacillus spp. were significantly increased (9.9 ± 1.88 and 8.99 log10 CFU/g, respectively) by dietary supplementation with liquid CLV compared to that in non-treated chicks (8.7 ± 1.22 and 8.51 log10 CFU/g, respectively). However, energy digestibility was increased significantly by 1.29% in CLV-treated chicks compared to the control chicks. This review highlights the findings associated with the utilisation of CLV biomass as a feed supplement and its effect on broiler growth and health.

Use of liquorice (Glycyrrhiza glabra) in poultry nutrition: Global impacts on performance, carcass and meat quality


Supplementation of poultry diets with medicinal plants containing bioactive molecules have shown promising results in promoting growth performance, enhancing feed efficiency, and improving carcass traits and meat quality. There are many studies using herbal plants and their derivatives involving liquorice (Glycyrrhiza glabra), while studies using only liquorice are very limited. Liquorice contains bioactive components such as glycyrrhizin and flavonoids, and has been linked to many pharmacological effects like immunomodulatory, anti-oxidant, antiviral and anti-inflammatory activity. Supplementation of liquorice in poultry diets had beneficial impacts on growth and performance by improving organ development. In addition, there are appetite and digestion stimulating factors in liquorice. Dietary liquorice supplementation at level of 2.5 g/kg showed the best results in broiler chicken, and demonstrated it can be safely used in poultry diets. Addition of liquorice in diets up to 0.5% inclusion before sexual maturity enhanced performance of laying hens. Furthermore, broilers receiving drinking water containing 450 mg/l liquorice under heat stress significantly improved feed conversion and economic efficiency. Abdominal fat in broiler chickens was decreased when liquorice was included at 2 g/kg in feed or 0.3 g/l in drinking water. Broiler chickens with access to drinking water containing 450 mg/l of liquorice increased the dressing percentage, with or without giblets. Carcass organoleptics were improved in birds receiving drinking water with liquorice at levels of either 1, 2 and 4 mg/ kg body weight. This review describes the chemical composition, health benefits and beneficial applications of the liquorice herb and its effect on growth and productive performance, carcasses and meat quality, which will be useful for researchers, physiologists, nutritionists, veterinarians, scientists, pharmacists, pharmaceutical industries, and poultry breeders.

In-silico investigation of genomic regions related to ascites and identifying their pathways in broilers


The importance of ascites in the poultry industry warrants a comprehensive systematic review and in-silico modelling to explain responses seen in previous studies in this field. By identifying the genes which are effective and relevant to different indicator traits of ascites in poultry, genes were separated base on chromosomes to determine the most effective chromosome in ascites. Consequently, 12 chromosomes have been discovered as containing effective regions on ascites incidence. Meanwhile, 24 genes including MPPK2, AT1, RhoGTPase, MC4R, CDH6, NOS3, HIF-1A, OSBL6, CCDC141, BMPR2, LEPR, AGTR1, UTS2D, 5HT2B, SST, CHRD, TFRC, CDH13, ACVRL1, ARNT, ACE, ACVRL1, MEF2C, and HTR1A affect ascites according to published studies. The results show that chromosome 9, with the presence of six related genes, chromosomes 1, 2 and 7 with three related genes and Z containing two genes have the most influence on the sensitivity to the ascites syndrome, respectively.

Variations of geese under domestication

  • J. KOZÁK

Man has been in interrelationship with wild water fowl for thousands of years. Yet, in that time, only two species of wild geese have been domesticated (13.3% of all true geese); the Greylag goose (Anser anser) in the fourth millennium B.C. and the swan goose (Anser cygnoides) in the second millennium B.C. From these two species, numerous breeds (181) have been developed. Compared to other domestic animals, the goose has varied less during domestication, aside from a few modifications in appearance, reproductive traits, internal organs and behaviour. It has increased in body weight, and hence became a non-migratory bird. Compare to the greylag goose (gander 2.8-4.1 kg, goose 2.5-3.8 kg body weight), the body weight of the Toulouse gander has increased by 331-421%, and the Toulouse goose by 286-364%. The African goose developed higher body weights (gander by 285-362%, goose by 292-311%) compared to the weight of the swan goose (gander 3.5 kg, goose 2.8-3.5 kg body weight). Conformation traits have changed, whereby the natural grey feather colour has changed to white in some breeds. Furthermore, sexual maturity has accelerated, and prolificacy increased. Egg production of a significant proportion of the European goose breeds has increased by 600-1000% compared to the greylag goose (5-6 eggs/goose). For example, egg production of the Chinese goose has increased by 875-1200% compare to the wild swan goose (5-8 eggs/goose), and the monogamous partnership typical of wild geese has turned into polygamous matings.

Fertility and hatchability in duck eggs: a review


The ducks are waterfowl belonging to the Anatidae family of cosmopolitan distribution. In production, obtaining ducklings at one day old is a major issue. Ducks are highly proliferating birds, and can lay between 45 to 150 eggs, white, blue or green depending on breeds. Obtaining day-old ducklings can be done by natural incubation with a broody duck or artificially in an incubator. Pekin eggs have greater hatchability than Muscovy eggs. The eggs of the Muscovy have lower values for hatchability (22.7% or less). During artificial incubation, fertility and hatchability are the most important indicators that must be controlled. Many factors are related to successful production, including environmental conditions during incubation. Among the elements determined by producers are housing and management system, season, nutrition, management of breeding stock, storage of eggs before incubation, fertility and cleaning eggs and equipment. According to some reports, laying hens have 78% hatchability compared to Pekin duck eggs in the spring, while in summer it is around 46.5%. The best hatchability is observed during the winter (57.68%), whilst during the summer it decreases to 54.14%. The reproductive characteristics of flocks, age, external and internal quality of eggs, male:female ratios, and presence of lethal genes are factors that directly involve breeders. The ratio 1:6 has been used satisfactorily in cases of shortages of males, although ratios of 1:4.3 to 1:10 cause reduced egg fertility of 75.9 to 49.6%. There are different methods used to improve the hatchability of duck eggs. Dipping eggs into some nutrient mixes (vitamins and amino acids) during the incubation period is one of the tools used to improve hatchability.

Red yeast (Phajfia rhodozyma) as a source of Astaxanthin and its impacts on productive performance and physiological responses of poultry


The red yeast Phaffia rhodozyma is considered as a useful source of astaxanthin (ASX) which is a carotenoid pigment widely used in the feed industry. Poultry cannot synthesise carotenoids, so they must obtain these pigments from diet supplementation with sources such as red yeast, as a source of ASX. Astaxanthin has health benefits including the protection against oxidative damage in cells, enhancement of the immune response and protection against diseases by scavenging oxygen free radicals. It has activities approximately 10 times stronger than that of other carotenoids and 100 times greater than α-tocopherol against reactive oxygen species. In recent years, Phaffia rhodozyma has become an important microorganism for its use in both the pharmaceutical industries and food. Dietary Phaffia rhodozyma addition at the level of 10 and 20 mg/kg in broiler diets positively increased weight gain by 4.12 and 6.41% respectively. The inclusion of ASX rich red yeast (100 mg/kg) in broiler diets for 14 days improved T-cell proliferation and IgG production by 111.1 and 34.6% respectively. However, the optimum level or feeding duration of dietary ASX rich red yeast addition for enhancing poultry productive, physiological and immunological responses has not been determined.

Heracleum persicum: chemical composition, biological activities and potential uses in poultry nutrition


Heracleum persicum (golpar) is an endemic medicinal plant that is commonly known as hogweed or Persian hogweed. It contains flavonoids and furanocoumarins that probably could stimulate both cell- and antibody-mediated immune responses. Besides, golpar has a substantial immunostimulatory effect on beta-lymphocytes and macrophages that played important role in antibody synthesis. Its extract at a supplementation level of 1- 2.5 ml/l in drinking water showed a remarkable increase in the total immunoglobulins (Ig) (70%), immunoglobulin G (IgG) (100%) and immunoglobulin M (IgM) (94%) titres and an increase in antibody titre against Newcastle disease virus (96%) in broilers. In addition, supplementation positively affected the feed intake (9.4%), weight gain (14.7%) and food conversion ratio (FCR) (8.7%) in broilers. Moreover, in several studies, it has potential as an antifungal, antidiabetic, hypocholesterolemic and growth enhancer agent; which endorsed its extensive contents of phytochemicals (terpenoids, triterpenes, furanocoumarins, volatile substances, flavonoids and alkaloids). It has a positive effect on the levels of glutathione (GSH), peroxidation lipids (MDA), the total antioxidant capacity of plasma or ferric reducing ability of plasma (FRAP) and glutathione s-transferase (GST), in addition to modulatory effects on liver enzymes including alanine transferase (ALT) and aspartate transferase (AST). After reviewing the published literature, it was apparent that golpar has multidimensional biological effects. Nevertheless, little research is available on the effects of golpar on productive performance and other health-related parameters in avian species. Hence, this review encourages veterinarians and poultry researcher to undertake further work to demonstrate the promising beneficial effects of golpar at effective levels to potentially replace the synthetic antibiotic growth promoters in commercial poultry diets.

The South Africa branch held its 36th Scientific Day in Pretoria in November 2018, with a record number of 402 attendee’s. The programme was focused on layers and breeders, and comprised a number of excellent speakers. Prof Martin Zuidhof from the University of Alberta gave two presentations on precision feeding and entertained the audience with some great video’s and anecdotes of individual feeding! Prof Maureen Bain from the University of Glasgow gave new insight into egg shell quality and ways to assess it, a topic becoming so relevant with the extended laying cycles expected of commercial layers. Peter Arts, of Hendrix Genetics, presented latest developments in breeding and also emphasized the advanced genetics in extended laying cycles and egg production achievable currently. Prof Sergio Viera from the University Rio Grande do Sul made presentation on the mineral requirements of broiler breeders, and the challenges in estimating requirements. Dr Fambies van Biljon discussed current concerns with Avian Influenza, and Dr Peter Plumstead presented his work on limestone quality and its impact on calcium and phosphorus availability and digestibility. The event provided a wonderful chance to network and catch up with old friends over lunch and tea. The AGM was also held during the day where the Barnard-Gous scholarship was presented to Sifiso Mthembu of UKZN to continue with his MScAgric in Poultry Science.

Save the date for the next Scientific Day which will be held on 30th October 2019 at the CSIR in Pretoria.
