Effect of different levels of sunflower meal and multi-enzyme complex on performance, biochemical parameters and antioxidant status of laying hens

Thanks to the authors for an interesting publication, but I think that the practical priority in the matter belongs to the research center of Danisco AS. 25 years ago they formulated the working concept "Sunflower + Enzyme = Soy". The employees of my company supported this idea, because in Ukraine (the number 1 country in the world in the production of sunflower oil and sunflower meal), the cost of sunflower meal at that time was three times cheaper than soybean meal. We did not pay attention to the legal restrictions that set in Europe the maximum allowable level of input of sunflower meal in the feed of laying hens is about 13%. A few years later, all poultry farms switched to diets with 25% - 30% sunflower meal, without reducing productivity. Of course, it was necessary to add some lysine, but this did not really affect the final cost of the feed.

Kindly share the metabolizable energy prediction equation of sunflower meal for broiler and layer. Thanks.
