REDUCE DIET COSTS WITH


NITROSHURE UREA A new encapsulated urea supplement is proving a cost-effective replacement for soya in the diet of lactating dairy cows – but without compromising the quality of feed. Nitroshure, manufactured by Balchem in the US and marketed in the UK and Ireland by AB Vista, is a rich source of both nitrogen and protein for ruminants. As a slow-release nitrogen supplement,


Nitroshure enables dairy nutritionists and producers to take a more flexible approach to feed programming. What’s more, its high protein density allows for a greater variety of ingredients in the diet, in place of other protein supplements. Mi c h a e l No o n a n , Bu s i n e s s


Development Manager for AB Vista’s GB and Ireland team, said: “We are delighted that we can now make this supplement commercially available to our customers in the UK and Ireland at a time when diet costs are at a record high”. “Nitroshure supplies cows with the


same amount of protein as traditional protein supplements. The cost of Nitroshure is equivalent to soya at a price of around £300/T. Therefore, a significant saving is possible based on current (and rising) soya prices of around £450/T. Dairy producers can make considerable savings by replacing soya in the diet with Nitroshure, while maintaining the quality and other nutritional benefits of the feed.”


NEWFEEDADDITIVEGIVES COWS


NUTRITIONAL BOOST Dairy farmers across the British Isles can now make sure herds get the very best from their diet, thanks to a new feed additive distributed by AB Vista. ReaShure is the first fully protected choline product to go on sale in the UK and Ireland, and can help improve cow health, milk production and reproduction. Choline is a vital nutrient for cows –


but, unprotected, it quickly degrades in the rumen before it can be properly absorbed.

As a fully protected choline, ReaShure will help cows get the nutrition they need during the pre- and post-calving transition period, for general health and milk production. By increasing choline availability to the


animal, ReaShure can maintain optimal liver function by reducing the accumulation of liver fat. As well as improving energy levels in transition cows, it should help improve herd fertility and minimise metabolic problems – giving an 8:1 return on investment in even the best-managed herds. Derek McIlmoyle, Technical Director


for AB Vista in GB & Ireland, said: “When it comes to providing nutrients, rumen microbes alone just cannot meet the demands of today’s high-producing cows. As the UK and Ireland’s first commercially available, fully protected choline product, ReaShure has been shown, through robust research, to offer the high levels of rumen protection and bioavailability that dairy herds need for optimum nutrition.”


NOVE L INSECT PROJ ECT COULD PROVIDE PROTEIN FEED


SOLUTIONS A project to develop novel insect-derived feed protein that could help replace expensive soyabean meal and fishmeal in poultry and pig diets has been announced by ABN’s parent company AB Agri. The project involves entomologists,


biochemists and nutritionists, combining the expertise within ABN with that of scientists at the Food and Environment Research Agency (Fera). Insect larvae will be grown on organic waste materials, then processed for use in animal feeds and initially evaluated in poultry. “With global protein supply currently


struggling to keep up with worldwide demand, and protein prices sky-high this year as a result, there’s a real need to develop new, sustainable alternatives,” explains ABN technical director Angela Booth. “This project is an exciting opportunity to see if the highly digestible protein in insect larvae could help meet that need.


“As a bonus, the organic waste substrate


is reduced in mass by around 50%, and can be used as a valuable fertiliser.” The aim is to have a viable pilot-scale


production system up and running by the end of the three-year project, which is jointly funded by AB Agri and the Technology Strategy Board. In addition to overcoming the technical production challenges, a strong focus will be placed on evaluating the feed’s nutritional value and its suitability for use as an animal feed, especially in relation to consumer acceptability.


DULCOAP E T ENT E S - 4 0 0 INCREASES INTAKE IN MEDICATED


FEED Appetence and feed palatability are key issues to achieve optimal performance, with smell and taste being the main factors affecting feed intake. While smell governs appetence, taste determines the acceptance or refusal of feed. The mechanisms involved in taste recognition are the same for all mammals, however, interpretation may differ by species or individual. Thus, a substance may result tasty for the human being but not for an animal. Aspartame is a good example, as it is sweet for humans but insipid for pigs. Interpretation also depends on previous experiences. For instance, bitter is a taste connected to discomfort. Its sensitivity is more marked than other tastes, being responsible for most of feed refusals. It is common to find bitter taste in vegetable raw materials and medicines. In the wild, bitter substances are usually harmful; in fact, many of lethal toxins found in poisonous plants are described as bitter alkaloids. In order to face this situation, Norel has created Dulcoapetente S-400, especially designed to mask the bitter taste and promote adequate feeding behaviour. In medicated feed for weaned piglets and when compared to a control group, daily feed intake was improved by 20.3%, average daily gain by 36.8%, and conversion index by 12.0%.
