DIY whole grain feed mix

[pinksapphire]

Basic Check? CHATGPT overestimates Protein content - its almost 17 based on my data sources. Fiber is a little high but OK, fat is (not surprisingly) low,. No sources of non-phytate phosphorus. Most of the P in that is unusable by the birds. Met is very low - I wouldn't recommend it for any birds of any age. Lys is very good (of course it is, half the recipe is pulses and legumes). Threonine barely makes the min recommend, but it does. Tryp is a trifle low. MKe is in the acceptable range (toward the lower end, the lack of fat).

Additionally, several of those ingredients, due to antinutritive factors, should not be used at the inclusion rates suggested - Winter Peas and Field beans, the primary protein sources.

Would definitely benefit from a product like Fertrell's Nutribalancer w/ Met, but still would not be my first, second, or third choice in feeding. Also, not the worst homebrew recipe I've ever seen. ChatGPT is making this easier for people to get at least a few numbers in the right ranges.

Thank you so much for taking the time to respond to my post.
Yes I don't fully trust chatgpt so didn't want to blindly go with what it said.
Sorry the protein content is actually based on what the information the farmer has supplied me with and not chatgpt.
I soak my grain in water for 2-3 days before feeding, do you think this would be enough to remove the antinutrients from the peas and beans, or what other protein sources would your recommend?
Any recommendations on sources of non-phytate phosphorus? Unfortunately the nutribalancer you recommended is not possible as I am in Ireland.

Being a small Island with a cold climate the crop availability is limited, I am trying to not rely on imported feeds.
Your input is much appreciated

I have a question about the free-choice kelp meal. Do you provide that for your ducks as well, and if so, do they waste it or eat a lot of it? Or do they just take a nibble here and there? I'd love to provide my ducks with kelp meal, and have been pondering on how I would probably offer it (free-choice or in their feed mix).

On the note of methionine, I wonder what subbing some of the wheat or oat portion of your proposed recipe for BOSS (black-oil sunflower seeds) would do to your protein percentage / methionine levels. I've read that BOSS is a reasonably good source of methionine. Might be worth looking into? BOSS is also amazing for feathers, which you probably already know.

Best of luck with the feed mix! I've been on this journey with my flock of 12 ducks. Still adjusting and refining my recipes...I imagine I will be tweaking and testing different things for a long time. It's part of the fun!

Yes the kelp is available for the duck also, I have never noticed them wasting it, it doesn’t go very fast so I think they just take a bit now and then.
I had been looking at BOSS but can’t find a good affordable source unfortunately. I will keep looking.
Thank you for your input

Is your protein content corrected for water? Those numbers looks they are based on % dry matter. Using a hard wheat (I assumed soft wheat) would help some, there is considerable variation in winter peas, and many field peas/field beans (cow peas, crowders, black eyed peas, etc) - I used a representative figure.

Soaking the beans and peas will help with some of the anti-nutritive factors, yes - how much will depend on a lot of factors - the color of the pea flower, whether its smooth or wrinkled, are both indicators of some typical issues - but ultimately it comes down to variety f pea, soil conditions, weather that year. Same with the field peas - the more color to them, the higher they likely are in tannins, but you also have concerns w/ phytate and trypsin inhibitors. HEAT helps with those, soaking is really good just to address some of the tannins. Boiled 30-45 min, you can include maybe up to 15% by dry weight, depending on variety. Possibly slightly more with the addition of enzymes.

No, we don't have enough experienced posters from Ireland, active on this forum, who get "into the weeds" on chicken feed that I can recall anyone recommending local alternatives to some of the resources we have available on this side of the pond, sorry.

on non-Phytate Phos (and your peas actually magnify this problem) best readily available options are animal proteins "meat" and milk. @saysfaa and @Perris have both provided old time recipes from the US (think 1940-1960s) that you might want to consider - I've got a link to some here - there may be some additional threads, I've not made recent search. Otherwise, you could look to something like dicalcium phosphate or calcium diphosphate as your free choice CA source as a way to add non plant P to the diet. Sometimes those can be found in health/vitamin shops, or ordered from Amazon.

https://www.backyardchickens.com/threads/interwar-recipes-for-chicken-feed.1605509/ has some British home made feeds with what was available in the 1930s and thereabouts.

Resources in Ireland are likely very similar to what is available in the UK. The feed I make is described here https://www.backyardchickens.com/ar...eat-tears-a-calculator-or-deep-pockets.78655/ with an update here https://www.backyardchickens.com/articles/wholesome-homemade-feed-2.79307/
