Regarding the need for choline in feeds, some points must be considered: 1. The content of choline in the base feed is not known exactly. It depends on its content in each feed ingredient. 2. Also, the availability of choline in the feed ingredients is mostly unknown (although supposedly high). In soybean meal we published a study demonstrating that the availability for broilers is 100%: MENTEN et al. A new method for determining the availabilityof choline in soybean meal. Poultry Science, v. 76, p. 1292-1297, 1997. 3. The requirement published in NRC (199%) has been conformed in a recent study we conducted. This requirement must obviously be met: LIMA et al. Estimate of choline nutritional requirements for chicks from 1 to 21 days of age. JOURNAL OF ANIMAL PHYSIOLOGY AND ANIMAL NUTRITION, v. 102, n. 3, p. 780-788, 2018.

Dear prof. Mentem. Thank you for sharing the experimental data your group has generated. It's very useful for these discussions. On internal trials in our company, (broilers between 1-21 d of age) with a similar set of diets and total calculated choline levels between 400 and 500 ppm, responses to added choline were quite similar and birds on the most deficient levels also developed perosis. This is a good model to test alternative natural sources of choline, since, as you have shown, it's quite easy that practical diets won't show any response to added choline. Simply replacing choline chloride by a substitute and by the lack of difference in performance to conclude that the product was as effective (if not higher) as it is not right. If you can not show a clear response to added choline, you can not make that conclusion. I agree 100% with Dr. Luc Goethals considerations.

Choline is good source in methylation reaction in liver, Prevent from fatty liver in both broiler and layer during high energy diets. good quality choline gives perfect results when oil content is high in layer diet.
