Natural Betaine benefits broiler chicks

Interesting. Question- Met and TSAA level in feeds.Bigger egg weight suggest partial replacement of Meth; additional vs.control. Breeders-even 2 kg/t feed looks economically efficient; just simple calculation: 2% more eggs hatched (of eg.200 eggs)=4 chicks more/hen, feed=60 kg/hen and additional cost (Betafin)is 0,6$.Not much. 4 chicks for 60 cents. I understand that the result is obtained due to betaine accumulation in egg yolk (as shown in trial 1- commercial layers).What was the level of betaine in yolk (both groups)? Similar results as in trial 1? Other egg measurements?

Very good points by Piotr but what you expect from Betaine contents of the yolk. My question with the author, if the betaine was used as replacement of Met or Choline or added on top? What is the cost to benefit ratio?

Tariq,I expect,that betaine accumulated in yolk is able to protect the embryo against various stress during incubation;temperature change, humidity.The benefit depends on chick price and betaine price.As you coud calculate (above) the 2% better hatchability is profitable with price 5$/kg Betafin.I'm afraid that the synthetic form (eg.HCl) will not work as good as natural (eg.solubility,osmoprotection).

Hi Piotr The yolk is a feed for last stages of chicks, so I don't think if betaine contents in yolk will not surpass your expected outcome. Regarding your comments on synthetic type of betaine, there are many good researches available and published in peer reviewed journals which shows that HCl form is as good as anhydrous form if supplemented on the basis of betaine contents (not replaced one product with other product) as Betaine HCl is ~78% pure betaine compared to ~98% in anhydrous basis.
