ISA FOCUS International magazine for all the relations of Institut de Sélection Animale 3 - January 2010 INCUBADORA MEXICANA AN EXAMPLE OF A SUCCESS STORY Some 60 years ago in Tehuacán, Puebla (central Mexico), the Romero family started a humble, one thousand layer farm with the goal to locally produce and market table eggs. This simple beginning was the base of the unprecedented success that the Romero consortium has today in Mexico. From left to right: Ing. Alejandro Romero (IMSA - CEO), Dr. Miguel Romero Sánchez (IMSA Founder) CONTENT THE EGG DESIGNED BY NATURE MODIFIED BY MAN LEADING JAPANESE HATCHERIES CONFER WITH ISA KEY TO SUCCESS, HISEX FROM CRIMEA A FOCUS ON QUALITY Incubadora Mexicana SA (IMSA), began operations in 1968 in order to provide day-old-chicks to the family farms, and has become a leading poultry company in the distribution of commercial and parent stock layers in Mexico, with a production capacity of 30 million chicks per year. IMSA is one of the various enterprises belonging to the IDISA Group (www.grupoidisa.com) founded by Dr. Miguel Romero Sanchez in 1963. His vision was to establish integrated operations to expand the family´s businesses, and this paid huge dividends. These companies and the products and services provided are: IASA, animal health and nutrition; ALPES, specific pathogen free eggs and embryos; NUTEK, feed additives and chemical quality control; IDISA, management services. Today, under the direction of Alejandro Romero, these companies have a base in the order of 980 employees and a combined annual revenue of over US$75 million. Market share In a market surpassing 135 million layers (115 million in first cycle) of which 92% are white and 8% brown layers, IMSA through its distributors holds a market share of 55 % for the white chick market with the Bovans White and close to 50% of the brown chick market with the ISA Brown. Leadership IMSA is the only company in Mexico and Central America with Leghorn type Grandparent Stock, which in turn supplies Bovans Parent Stock for its own operations, as well as distributing throughout the main poultry producing areas in Mexico, giving the Bovans White line indisputable leadership. Current production of Leghorn white breeders is 600,000 birds per year, 60% of which are for the company’s own use, while the balance is sold in the states of Sonora, Durango, Puebla, Nuevo Leon and Yucatan. Services The role of IMSA towards the poultry farmers does not end with the delivery of replacement flocks; on the contrary, it is only the beginning of its commitment. With the help of its associated companies, and also that of ISA, it offers the most complete array of services from technical assistance in poultry management and production to chemical and biological diagnostic support; all this backed-up by the most complete sales and support department that exists in Mexico’s Poultry Industry. IMSA is constantly reemphasizing its mission to work with the poultry farmers in producing animal protein of the highest quality at the lowest cost.

BY PROFESSOR SALLY E. SOLOMON, SENIOR RESEARCH FELLOW GLASGOW UNIVERSITY THE EGG DESIGNED BY NATURE - MODIFIED BY MAN Mother hen to freshly laid egg – “in three weeks time you will hatch as a chick”. Consumer to box of six medium sized eggs – “tonight you will be an omelette, soufflé, hard boiled, scrambled, poached, separated and made into meringues, mayonnaise etc.” Professor Sally E. Solomon Culinary dreams - packaged first by the hen then mechanically sorted and packaged in a variety of light weight containers before being examined finally by the consumer prior to purchase. But do colour, size and texture accurately predict the ability of the contents to foam and set in that most demanding of laboratories – THE KITCHEN? The answer is no. Albumen Quality A thick egg white is a symbol of freshness. During storage, however the consistency of egg white changes and it becomes more liquid. It also loses its foaming capacity and so storage conditions must be addressed before and after purchase – BUT thick egg white has a more fundamental role to play in egg formation, it physically supports the membrane fibres which retain the egg contents prior to shell deposition. The egg is the end product of the complex interaction between a variety of biological systems, shells will break before use, yolks do occasionally leak into the egg white and the latter despite critical examination in the packing station will often contain a variety of inclusions (blood and meat spots). Can they be avoided? Is the perfect egg achievable? Shell structure From the point of view of shell structure, variability is to be anticipated. Over a period of twenty hours, calcium salts, derived from feed and bone turnover and assisted by a protein framework, grow onto the paired shell membranes to form the multilayered testa. In brown egg layers, the pigment component is added during the final stages of shell formation and occurs in greatest concentration in the cuticular layer. Absence of this final protective layer, a common phenomenon in both breeder and layer birds, robs the egg of its first line of antibacterial defence and leaves the gas exchange pores, which penetrate the entire thickness of the shell, patent and so a portal of entry to a variety of micro organisms from the environment. That any egg will break if it is hit hard enough goes without saying but many eggs break without undue force and cases such as these demonstrate the fact that all shells are structurally flawed to some extent. Most of these flaws initiate within the basal layer of the shell (the mammillary layer) giving rise to micro-cracks which when further impacted become unstable and migrate through the thickness of the shell. So how do the flaws originate? It is probably true to say that in a well formulated diet, calcium is rarely the limiting factor, although external conditions may reduce the bird’s appetite in which case supplementation with oyster shell may be advised. Other features of egg formation should however also be considered. Prime amongst these is ALBUMEN QUALITY as influenced by disease and environmental stress and the effects of both on the physiological status of the oviduct. The normal cuticle with a patent gas exchange pore. In the absence of such support the fibres fail to form a regular interlacing network and the nucleation sites which are of membrane origin and serve to attract calcium salts from the oviducal fluid become irregular in their distribution – the result – a wrinkled shell. Under conditions of stress the oviduct sheds patches of surface epithelium i.e. the cells partially responsible for the production of many of the proteins necessary for shell formation. Stress often encourages the bird to retain the egg in the shell gland pouch past the normal time of oviposition. When laid, the egg will display a variety of surface defects – calcium dusting, rough concretions and will inevitably be down graded. The contents, however, could still be perfectly acceptable. Meat and Blood Spots If patches of epithelium are sloughed off from the magnum as the result of a stress event, the fragments can become incorporated in the egg white. These so called meat spots vary in their appearance under the microscope and have been classified into three types a.) soft tissue, b.) tissue plus blood cells and c.) calcium salts. The latter derive from a precise sequence of events beginning with a failure in the organisation of the interlacing network of membrane fibres. The latter are normally laid down in such a way as to physically inhibit the inward migration of calcium salts, but if the egg white onto which the fibres are depositing is of a fluid consistency then the continuum of the inner membrane can be breached and calcium ions once they have reached the egg white, will in the presence of calcium binding proteins precipitate out in crystalline form. Technological advances in on-line quality control mechanisms select against most eggs with blood spots. Located as they normally are between yolk and albumen, they originate at ovulation when some of the fine blood vessels surrounding the yolk mass ► haemorrhage. Normal mammillae. The spaces in the caps were formerly occupied by the membrane fibres. Yolk Quality The lipid rich yolk mass does not escape criticism. Yolk colour, mottling and the fragility of the perivitelline membrane all give cause for concern at some point, normally after purchase. Colour is easily manipulated by diet and indeed is used to satisfy specific regional demands. As for mottling and the strength of the membrane containing the yolk mass, a two way transfer of contents must be considered i.e. fluid from egg white entering the yolk and yolk leaking into the egg white usually when the egg is broken for the purpose of food preparation. Environmental and Nutritional Influences It must be stated that rarely do all these failures in construction and composition of contents occur simultaneously but that they do occur underlines the need for the use of stringent quality control measures. In terms of environment, the identification of potential stress factors ranks number one. Analysis has shown that high temperatures and noise (e.g. overflights) can have a negative effect on egg production. The literature regarding bird housing and product quality is prodigious, but to summarise, an environment which permits the bird to express its full range of behaviours is preferred i.e. free range with access to shelter or an enriched cage system with access to perches and nest boxes are the preferred options. Even in these ‘ideal’ situations however, the bird will occasionally lay a poor quality egg demonstrating the fundamental fact that no two birds are the same and the conditions that favour the reproductive stability of one will not necessarily favour its neighbour. Within the flock situation it is impossible to treat birds individually; thus when a disease situation presents itself, all birds are treated and if the percentage of poor quality shells increases then dietary intervention is inclusive – such is the nature of the operation. The pressure to lay on average 300 eggs per annum puts a strain on reproductive performance. In general terms egg quality peaks at 30 week of bird age and slowly declines after 40 weeks. The question is can age be defied, can the effect of increasing egg size with its attendant shell thinning be offset by genetic manipulation or dietary intervention? Fewer eggs per bird per laying year would initially go some way to addressing the poorer quality at the end of lay but the financial loss might mitigate against such drastic measures. As for diet, the market place offers many solutions. Of particular interest is the use of organic selenium. It appears to have a broad spectrum effect on egg quality viz. enhanced yolk membrane strength, improved albumen height and more recently has been shown to decrease the range of structural defects in the egg shell at the end of lay. Trace minerals perform a variety of functional roles in many biological systems. In its role as an antioxidant selenium is known to mop up free radicals. In a healthier oviducal environment, cell function will be enabled and the protein expression required of the cells lining the oviduct facilitated. In The Supermarket At the point of sale, no space is created for the normal vagaries associated with the process of egg formation. In the language of the supermarket, apples are round and shiny, carrots clean and regular in shape and eggs are intact and free of external blemishes. With reference to the egg, intactness is a must but downgrading on cosmetic grounds should be discouraged. ‘Variety’ as they say ‘is the spice of life’ and the contents should not be judged on external appearance. Informed choice requires education and with education comes a degree of freedom for the consumer to select from the extensive range of shell textures and colours which the bird will lay during its short but prolific reproductive life. VIV EUROPE 2010 The Netherlands April 20 - 22, 2010 Hall 11, booth B 014 We look forward to seeing you in Utrecht, The Netherlands. For registration please visit our website www.isapoultry.com DUTCH MINISTER OF AGRICULTURE VISITS SOUTH-EAST ASIA Mrs. Gerda Verburg, Minister of Agriculture, Nature and Food Quality of The Netherlands visited South-East Asia to strenghten the relation with the key players in the market. On July 3-4, 2009 she visited Thailand and on July 5-6 Vietnam. The Ambassador of the Kingdom of The Netherlands in Bangkok, Mr. Tjaco van den Hout invited 80 VIP’s from the Food and Agricultural industries to meet with Minister Gerda Verburg. The leading companies with strong positions in Thailand were represented. ISA / Hendrix Genetics was invited, and was represented by Dr. Pornsak Hirunpatawong. ISA is the main supplier of PS for layers to Thailand with a market share of 78%. Minister Verburg appreciated the conversation she had with Dr. Pornsak Hirunpatawong and was clearly impressed with the position of ISA in not only Thailand but also in all surrounding countries. From left to right: Minister Gerda Verburg (Minister of Agriculture, Nature and Food Quality of the Netherlands), Dr. Pornsak Hirunpatawong (ISA - Area Manager SouthEast Asia) KEY TO SUCCESS - HISEX FROM CRIMEA The biggest Ukrainian breeding company “Imeni Frunze” celebrated its 80th anniversary and halfcentury in poultry. The company’s good name is well known in Ukraine and beyond its borders. “Frunze” Holds Annual Conference Recently, the breeding company held the annual conference for its clients in the Crimean resort of Alushta, which attracted representatives from 38 farms in Ukraine, Russia and Moldova. In his opening remarks, the Director of “Frunze”, Mr. Boris Yakimchik thanked the clientele for their trust, and pointed out that in the last year, the company sold 8 million Hisex White and Brown day-old chicks. This was almost half of the total volume in the country; and orders for 2009 may be even higher. Parent Stock Imports and Disease Control Twice a year, “Frunze” imports Hisex parent stock from Hendrix Genetics. Hisex is highly productive, robust and docile layer, which is perfectly adjusted for long production cycles and gives eggs with strong shell and ideal weight until the end of laying cycle. In order for the commercial farm to realize the genetic potential, the birds must be absolutely healthy. That is why “Frunze” exerts its maximum efforts to housing and transport sanitation, and to disease control. Sanitation and immunity are regularly monitored, according to Chief Veterinarian Alexey Kotov. Incidentally, the “Frunze” farms are locasted just a few hundred meters from the Black Sea, providing birds with natural iodine in the air they breathe. Clients appreciate the efforts of the company. The director of “Nikolaevskaya” farm Mrs. Tatiana Illarionova is happy with its supplier of chicks: “Last year was difficult to our company but despite these, let’s call them sub-optimal conditions, Hisex pleasantly surprised us with its livability and production higher then standards. We worked with different breeding farms and I can say without doubt, that “Frunze” provides not only an excellent bird, but the best service in the industry. From left to right: Mrs. Marina Gudima (PPZ Frunze-Ukraine Chief of Breeding Department), Mr. Boris Yakimchik (PPZ Frunze-Ukaine - director), Pavel Kolnik (ISA - Technical Manager North & Central Europe), Yaroslav Nemirovsky (ISA Area Manager CIS Russia & CIS countries) Having two hatcheries, special chick trucks and the biggest breeding flock in the Republic, the company can deliver more then a hundred thousand vaccinated day-old females at once for distances up to 2,000 km. This is very beneficial since today many farms after the reconstruction have vast flocks and the factor of uniformity became crucial. Hendrix Genetics to acquire Joice & Hill Poultry Ltd. The Shareholders of Joice and Hill have completed the acquisition of 100% of the shares of Joice and Hill by Hendrix Genetics. Hendrix Genetics held via its affiliate Institut de Sélection Animale B.V. already 40% of Joice and Hill. Joice and Hill, with Nick Bailey as Managing Director, produces and sells around 5.5 million day-old chicks per year. Together with Tom Barron hatchery, the other ISA distributor in the United Kingdom and Northern Ireland, they hold more than 40% of the market.

Hendrix Genetics (already owning 34% in Integra) has completed the acquisition of the majority shareholding of Trouw Nutrition Biofaktory in Integra in Zabcice, Czech Republic. Integra, with Petr Krul as General Manager, produces and sells around 7.5 million day-old chicks. The chicks are delivered to many Central -European countries. The market share of Integra in Czech Republic is over 60%. LEADING JAPANESE HATCHERIES CONFER WITH ISA From September 15 to 24 the Presidents and the CEO's of the leading Japanese layer hatcheries visited the USA, France and The Netherlands to have a closer look at the Hendrix Genetics / ISA company and to learn more about the performance of the ISA products in some of the leading egg markets in the world. Visit of Portuguese Egg Producers in ISA France Meetings were organized with the top management of Hendrix Genetics and ISA to talk about the specific needs of the Japanese market and to explain what ISA has done the past several years to further professionalize its company and to breed layers that are designed to meet the requirements of the Japanese layer industry. The Japanese delegation was very impressed with what they saw and heard. ISA, together with Nutroton Multiaves organized a visit of the Portugese egg producers in ISA France. Nutroton-Multiaves is our Iberian exclusive distributor of ISA Brown and Dekalb White - under the leadership of Mr. Joâo Rebello Cotta. Visits to large poultry operations with over 2 million layers were made and also visits to farms with cagefree production systems to see the performance of the products. Also visits were made to hatchery Ter Heerdt in The Netherlands and SFPA in France, ISA's distributors that successfully supply around 50% of the layers in both markets. The most important conclusions drawn after the visit were: • ISA/Hendrix is a very professional multispecies breeding company with top positions in all species they are active in. • ISA has excellent health control programs in Pure Line, GGPS and GPS, and will match all quality standards set by the Japanese poultry industry • ISA understands the specific needs of the Japanese market and has developed products that fit to these requirements. • ISA’s products are more than competitive, and in many cases better those of the competition. • All ISA's products have superior HH egg production, and show excellent performance in internal and external egg quality. Or, as shortly summarized by 1 of the participants: "ISA, the right products and the right company !" 1st row from left to right: Nobuyuki Ohata, Thijs Hendrix, Takashi Tomaru, Osamu Niinobe, Chuei Iwamura, 2nd and 3rd row from left to right: Andy Hansen, Osamu Morioka, Yukimitsu Sakakura,Yasuo Akagi, Frans van Sambeek, Arian Groot, Kazutoshi Ueno, Servé Hermans BY DR. PETER HUNTON, POULTRY CONSULTANT AND PAST PRESIDENT, WORLD’S POULTRY SCIENCE ASSOCIATION QUALITY Firm, thick albumen is a feature of the freshly laid egg, but Prof. Solomon emphasizes its role in shell formation as well. Lower quality albumen, resulting from age, disease, or other factors may result in imperfect shell formation.. While producers may have limited ability to control albumen quality, the link between it and shell quality is important. When both decline, there will be increasing incentive to divert eggs to further processing, while the eggs from younger hens exhibiting better albumen and shells are used for shell egg sales. Dr. Peter Hunton There are two types of quality attributes associated with eggs. Firstly, those that have negative connotations for consumers, such as cracked or dirty shells, internal faults like blood and meat spots, or very thin white. Then there are the positive attributes, which would include "perfect" shell colour and texture, and superior internal quality associated with freshness. The Perfect Shell? As Prof. Solomon emphasizes in her feature article in this issue of ISA Focus, we must never forget that the laying hen thinks she is creating an egg that will be incubated and hatch into a perfectly formed chick. Our use of the egg as a food item is incidental, but nevertheless, many of the quality factors that contribute to hatching success are also beneficial in terms of the consumer's concept of quality. The goal of the perfectly formed shell is one shared by hatching egg and commercial egg producers. For many years, researchers and farmers concentrated on nutritional factors like calcium, vitamin D and other nutrients. While it is clear that nutritional deficiencies can cause havoc in terms of shell quality, it is also obvious that not all flocks that receive adequate or even better nutrition produce good shells. Some of the environmental factors involved are highlighted by Prof. Solomon. While it appears from research that free-range conditions may be optimal, from a practical point of view the majority of the world's layers are still kept in conventional cages. In these circumstances, factors like floor and feeder space allowance, cage design and environmental stability, and the absence of obvious stress conditions all contribute to the ability of the hen to form an acceptable egg shell. Dr. Solomon also refers to the use of organic selenium and trace minerals to enhance shell formation. Cool Chain Needed For Optimum Quality It has long been known that the most important influence on albumen quality among eggs at retail is the time and temperature of storage. Modern egg production and marketing channels permit passage of eggs from the hen to the grocery store in 3-7 days. If eggs are held in a suitable temperature during this period, (no greater than 12ºC) they should show minimal decline in albumen quality by the time they reach the consumer. However, outside of North America, many countries still fail to manage egg storage temperatures in this way. Holding, transporting and selling eggs at room temperature, often 20ºC or higher, can seriously affect albumen quality, to say nothing of encouraging microbial growth if eggs are contaminated. Unfortunately, the producer alone cannot be responsible for all the stages in the marketing chain. But cooling eggs immediately after gathering (and grading in in-line operations), is a good start, and may provide the producer with some leverage to insist on extending the cool chain further along the marketing process. Egg quality is important to everyone in the production chain. ISA has always included shell and internal quality as important selection traits in its breeding programs. Producers are often paid on the basis of quality in terms of downgrading faults, but bonuses for superior quality are also a way of improving overall quality in table eggs. Attention to all of the factors affecting shell and albumen quality, both those detailed in this issue of Focus, and others we may deal with in the future, are mustdo parts of management. Egg marketers have an important role to play in terms of handling and storage (even short-term) to preserve the excellence that the producer has placed in the product. The development of coolchain procedures where they don't already exist could be the egg industry's greatest contribution to consumer satisfaction with egg quality in the next decade.
