Biologically active amino acids synthesised through cell pathway synthesis have shown considerable growth promotion as extra cellular transcription factors by increasing mRNA thus enhancing metabolic mechanisms from within nucleus and reaching DNA, it has increased immunity and reduced the feed requirement without compromising the regular growth parameters.These factors have increased the milk output by 10%, fat by 15% as per trials conducted in Mexico. In poultry trials reduction in the usage of antibiotics, broilers growth period less than 42 days, reduction in feed, increase in immunity, maintaining normal egg production by minimising the stress/shcok effects have been observed. aliabiosys@gmail.com

for mr robert gauthier , you are correct only if these xylanases are fungal xylanse but we can only use bacterial xylanse enzyme very succesfully on corn - soya diets as the bacterial xylanses are the only xylanase which can work on the non soluble part of the arabinoxylanse but the fungal xylanase can not do any effect over it asaadsabbagh@yahoo.com
for mr robert gauther , you are completly correct if you use fungal xylanase becuse it has no effect on insoluble part of arabinoxylanse ,and as the highest proportion of ax fiber in corn are insoluble so we have to use only the bacterial xylabse , it is the only type of xylanase enzyme which can act on the insoluble part of ax fiber so can give a good resultes with corn - soy rations
The use of enzymes in poultry diets is very useful tool to improve performance when barely, wheat and triticale are the main carbohydrate source. However, there are some interesting results about the role of enzymes in maize-soybean based diets, although, full and consistent responses was not almost achieved. There are also results about the use of enzymes in broiler and layers diets, however, direct experiments to compare their response is missing (to the best of knowledge), however, common believe is that broiler is more affected than layers and birds of younger ages are more influenced than older ones. The use of enzymes should always depends on diet composition and the match between enzymes activity of the cocktail and substrate (target substance) in the diet.
enzymes are substrate specific and one have to choose enzyme combinations based on the raw materials he is using in his formulations.Enzymes can increase the undigested percentage of any ingredient to some extent and using enzymes over the dose indicated may not yield good result. how can i check the enzyme activity after the feed is pelleted.
Arabinoxylanes forms also the major NSP fraction in Corn. However they are completely insoluble. So an enzyme (only Xylanase!) will have only effect if it is able to cut the insoluble fraction ! It is known that the bacterial Xylanase has a significant effect !
Developing enzyme preparations for animal nutrition is done by matching the appropriate enzymes to the substrate present in the avialable feedstuffs. There are ample opportunities in legumes such as soy-bean meal. Impextraco has developed a multi-component enzyme preparation for use in maize/soy diets and other diets rich in legumes. Zympex 008 contains alfa-galactosidase, beta-mannanase, pectinase, beta-glucanase, xylanase, protease, amylase and cellulase activity. alfa-galactosidase breaks down the antinutritional galacto-oligosaccharides; beta-mannanase splits mannan-polymers to mannan-oligosaccharides (MOS). Supplementing corn/soy diets with Zympex 008 gives significant improvements in growth rate, FCR, energy and ileal amino acid digestibility in broilers. More information is available on request. www.impextraco.com
in my opinion The use of corn-soybean mael-based enzymes such as beta mananase in the poultry feed is very important for digestibility of manann and other oligosaccharide and reduce viscosity of digestive tract.in my country Iran recently we use some enzyme for corn-soybean meal-based diet on broiler feed and the result of these enzyme was very good. mehdiebrahimii@gmail.com
I am a poultry nutrionist and consultant in Namakkal,Tamilnadu,India.I am using multienzyme in diet of both layers and broilers and giving good results.Let me know, How much amount of enzymes can be used in one ton of feed.At present I am using 500g of enzymes per ton of feed.If i use more than 500g is it useful.
Dear Dr. Yegani I'm PhD student in poultry nutrition. would you please send me a copy your paper. and if possible a copy of "Enzymes for the feed industry: past, present and future Author: CHOCT, M.1 Source: World's Poultry Science Journal, Volume 62, Number 1, March 2006 , pp. 5-15(11)" Naser Tehran Iran
I think enzymes will show the beneficial effects when add in the diets (corn-soybean based diets) for young chicks. Adding enzymes in adult poultry probably will not show the beneficial effects. Anyway, it will show the good result for adult poultry when the nutritonal content of diets are decreased from the standard recommendation. Since enzyme additional can increasing digestibility of nutrient but poultry requirement is limitted.
