NEW BOOK PROVIDES FRESH INSIGHT INTO THE USE OF


ENZYMES IN SWINE FEED Feed additive enzymes are set to play a key role in shaping the future of pork production efficiency, according to the contributing authors of a newly published book. Members of the senior research team


from animal nutrition technology company AB Vista were asked to contribute a chapter to Volume 2 of Achieving Sustainable Production of Pig Meat, a reference book which aims to provide the latest insight for researchers and anyone involved in supporting the industry. “Our contribution is essentially an


update on the use of three classes of enzymes - NSPases, phytases and proteases - in pig nutrition,” said Dr Mike Bedford, Research Director for AB Vista, who produced the chapter in conjunction with the company’s Senior Research Manager Dr Carrie Walk. One of the key messages is that there


is more than one way to use phytases, he said. “In the past, phytases have simply been used to extract phosphorus out of the diet, but we think that people should also be looking at them as a way of maximising nutrient extraction from feed.” The potential for reducing antibiotic use


by adding NSPases to feed is also covered in the chapter by Dr Bedford. As well as chapters on nutritional


topics, such as the use of exogenous enzymes, growth promoters and probiotics, the book, published by Burleigh Dodds Science Publishing, covers pig breeding and the practical use of the pig genome mapping for molecular breeding techniques.


NEW RESEARCH HIGHLIGHTS OPPORTUNITY TO IMPROVE THE


IRON STATUS OF PIGLETS Iron deficiency could be reducing the performance of piglets post-weaning, despite the routine use of iron injections and feed supplements. Recent data from Canada shows that,


of approximately 1,000 pigs tested on 20 commercial farms using standard iron protocols, around 30% had low iron status or anaemia at weaning. This was associated with a loss in performance post-weaning. Dr Peter Wilcock, North America


Commercial Manager, AB Vista explained that a more wide-ranging perspective was needed, in order to bring about solutions for pig producers: “To address the wider issue of anaemia on-farm, and investigate ways to mitigate the problem, a more holistic approach is required, considering other possible ways of boosting iron intake.” The new study showed that adding high levels of phytase to starter feeds could


increase the iron status of piglets, improving FCR and daily gain. This research is particularly important


as economic pressures change the way pigs are produced, said Dr Wilcock. “The move away from animal protein


based starter feeds in favour of those based more on vegetable sources may meet regulatory requirements and help to contain costs, but it also increases the level of dietary phytate. With phytate being well recognised as binding iron, it will reduce the availability of iron to piglets… Combined with the trend towards larger, faster growing litters, this means that the risk of iron deficiency in piglets is increased.” Dr Wilcock explained that the addition


of high doses of phytase to starter feeds can achieve near complete breakdown of phytate and its lower isomers, increasing available iron and resulting in improved post-weaning performance. In this particular study, weaner pigs


were given different doses of modified E. coli phytase with high phytate affinity, to break down the phytate component of the vegetable protein. Assessment of iron status 21 days after weaning showed that, as the dose of phytase was increased, the iron status of the piglets improved in proportion. This in turn was reflected in improved growth and FCR.


NUTRIAD LAUNCHES MYCOGUT


ACADEMY Multinational feed additives producer Nutriad received customers and distribution partners in Belgium for the inaugural sessions of the MycoGut Academy. In close cooperation with the University of Ghent an interactive poultry focused program was designed, that included practical and class rooms sessions. The international group of industry professionals from the Middle East that attended this first edition rated the event highly. As consumers and governments across


the world push for a restriction on the use of antibiotic growth promoters in animal production, Nutriad is taking the lead in offering high quality solutions that address bacterial challenges. As there is no single additive that replaces antibiotics, Nutriad promotes a combination of products from different platforms. Radka Borutova, Business Development


Manager Mycotoxin Management, presented on Clostridium Perfringens induced necrotic enteritis, highlighting the importance of focussing on predisposing factors that can influence the severity of the challenge, such as Mycotoxicosis. Dr. Gunther Antonissen from the


University of Ghent made a valuable contribution by elaborating on Deoxynivalenol and the development of necrotic enteritis in


broilers. The practical session at the veterinary


faculty of the University of Ghent was one of the highlights of MycoGut. It allowed attendees to learn more on identifying necrotic enteritis and different types of mycotoxins, but also to see the incremental effect of mycotoxicosis on bacterial challenges.


ZETADEC CELEBRATES ITS 10 YEAR BIRTHDAY WITH MINI SYMPOSIUM


“FROM PLANT TO PELLET”. The Dutch research company Zetadec celebrated its 10 year anniversary with a mini symposium entitled “From plant to pellet”. Zetadec was founded in 2007 by Menno Thomas and over the past 10 years has steadily grown into a worldwide acclaimed company in research and development in compound animal feed and fertilizer production. The symposium was chaired by


Jacqueline Wijbenga, chief-editor of De Molenaar. Ate Ludwig, director of N-xt Fertilizers discussed the degradation of arable soils and the resulting loss in quality of human food and animal feed. Professor Wouter Hendriks, Wageningen University and Research and Utrecht University addressed recent results with respect to the effects of technological treatments in relation to the nutritional value of feed ingredients. “Standard feed manufacturing technology is not well suited for breakdown of recalcitrant fibres.” Menno Thomas discussed fundamental


aspects of feed production which up till now did not receive proper attention. ”Further understanding and subsequent use of physical processes in feed production will lead to improved nutrient utilisation in the animal and a better efficiency of the feed production process. “ In addition, the new company style was presented to the symposium attendants.
