    new research debunks trad views on nutrition

    Good afternoon Texas. Its a popular topic around here, for those that get past brand name and the marketing descriptor, want to make apples to apples comparisons of feed labels. and depending on where you are in TX, you might want to check out @West Feeds . Reasonably priced, generally very...

    new research debunks trad views on nutrition

    My first thought is that waste amino acids in the droppings will overwhelmingly be the ones their diet already provides in excess - which is why they end up wasted in the first place. Not all protein is the same, and some amino acids aren't interchangeable. Those are the ones whose inclusion...

    Protein for diet advice

    Also, while I prefer a 20% CP feed, the Amino Acid profile is more important than the CP, and the performance differences between an 18% CP and a 20% CP is minimal. The differences between 20% and 21% are smaller than you will ever notice.

    Nutritional breakdown for layers

    Might I suggest: National Resource Council, Nutrient Requirements of Poultry, Revised 9th Edition (1984) Free Download. Good reading. A little behind the times, 10th edition is in the works. Most of us treat those recommends as minimums. Jump to p20 for charts. If you want to start with...

    Making a healthier feed

    ...am to attempt it. Most feed recipes you find on line don't stand up to their claims (typically re: crude protein) and almost none look at Amino Acid Balance, mKe, fat & fiber levels, non-Phytate phosphorus sources, key vitamins & minerals. Subbing corn out of a recipe is relatively easy...

    Giving chickens corn that is soaked in 5 gallon bucket of water good??

    ...nutritional excesses and deficiencies as corn. Both are low on protein and high in fat. Most likely, the bird seed lacks the balance of amino acids needed to make efficient use of what prootein it doess contain - but as there is great variety in birdseed, I can't say that with 100%...

    I'm back [and will try to return to the prior pace of Commenting]

    .3 Met and .7 Lys are the old NRC recommended minimums (jump to p5) for adult laying production hens based on a 100g/day diet. If you want to read the whole of the old paper, India maintains a copy here (slow download). Based on my readings, and my flock's purpose, my own targets are about 15%...

    All purpose feed

    ...and stock pellets are high fiber, low protein - either 10% or 12%. That protein level is WAY too low to support health chickens, the amino acid balance is wrong (methionine levels too low, often others as well), while the high fiber that the goats (with their ruminant stomachs) absolutely...

    Cost Effective, High-Protein Food Sources

    ...a commercial feed - in spite of including a Met suppliment. Under no circumstances would I feed that to my birds. Met is the hardest of amino acids to replace. and yes, as @Ridgerunner said above, you need to offer free choice calcium as well - oyster shell is the most popular choice...

    ...and waste protein is excreted daily, largely in the form of nitrates and the well known compound, Ammonia. CP, of course, is composed of amino acids. When the amino acids are well balanced to the chicken's need, there is very little waste, and thus, fewer nitrates and ammonia compounds to...

    I have been trying to make my own feed/seed mix and want to if this is good

    ...to perform similar purpose to widespread use of soy meal (here in the US) or a quality animal/insect/fish protein source to work with, target protein levels (and a good amino acid profile w/i that crude protein number) can't be achieved. And that's before considering vitamins, minerals, etc.

    Confused on different feed selections

    ...who understand that Crude Protein is an imperfect indicator of whaat we really want to know - Methionine and Lysine content, two critical amino acids. Everything else needs to be right too, of course, but Met and Lys matter. Which one matters more depends on the purpoosee of your flock...

    Fermenting Chicken Feed

    ...is used to break something down into component parts - in this case, releasing vitamins (like the B Complex), breaking proteins down into amino acids, and freeing other nutrients into more digestible, more bioavailable, forms. and it says "hatching" under your name based on your your trophy...

    Fermented feed vs crumbles/pellets

    There is a "perfect protein (Ideal Protein)" theory of chicken (and other critter) feeding, based on providing a balanced array of amino acids to minimize waste. Its a good theory, so far as it goes, but it arose at a time when Methionine couldn't be directly measured, and there were some...

    Protein content in feed

    ..."game birds" that is supposed to feed, but I certainly wouldn't feed it to my chickens or ducks. Crude protein is low, and the balance of amino acids is way off - that's about 1/3 the Methionine chickens need as a recommended minimum. Lys is about half where it should be as a minimum...

    Overwhelmed With Feed Thoughts, Please Help!

    ...Niacin content is EASILY fixed with a little nutritional yeast - which will also increase certain vitamins, total crude protein, and all amino acids, including the critical Met and Lys. Depending on how much feed you need, and the cost of nutritional yeast at your local grocer, Chick...

    Is this feed recipe healthy?

    the problem being, you can't make a healthy feed with those things. Corn is a high energy, low nutrient source. In terms of its Amino acid balance, its across the board pretty much evenly deficient, because its crude protein is very much sub par - likely the lowest of any ingredient that isn't...

    Help needed, What food do I put the flock on?

    Met and Lys are both Low. Low Met is unfortunately common in Organic feeds. Its the amino acid most associated with connective tissues - skin, digestive tract, cartilage, ligaments/tendons, etc. Because the operation of its digestive system is a substantial portion of its immune mechanisms...
