    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...

    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...

    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.

    Topic of the Week - "Off-grid" Feeding - Homemade feeds, etc.

    Thank you for suffering thru the whole video. I trust your judgement. I sampled a couple seconds before pulling out my soap box.

    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...

    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...

    Depends on Age and breed (purpose). Here are the old NRC recommends for hens and broilers p3 and 4. Metastudy for layers. and here is what Cobb says about their own broilers.

    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...

    Chicken feed

    ...are forced to do so. We also know that - given options - they are reasonably good at selecting from a range of feeds to balance their amino acid needs. However, absent nutrtionally dense options, chickens wil prioritize crude protein over balanced amino intake, and can suffer nutritional...

    Thin egg whites

    ...supposed to raise birds, mostly by people selling something, or by people who themselves have bought in to what was being sold. The key amino acid in membrane formation is Threonine. There are others, but almost all of them are amino acids the hen can make on its own. Threonine, however...

    Things I don't feed my chickens😊

    ...its daily protein intake for repair, for growth (if it is not yet full grown), for feather replacement, and a few other functions. The amino acids it can't use during that metabolic cycle it excretes - that's the primary source of the nitrogen in their deposits. If they are short another...

    Best whole grain feed

    ...eaten with the grains. There is no combination of common whole grains, which will meet a chicken's dietary needs - particularly certain amino acids making up the total crude protein - without either requiring that they eat far more feed than they typically would consume, grossly exceed their...

    Cornish X on 18% feed from start to finish - the results

    I offered only because you had asked "I still need to do the math on how economical is was compared to buying feed, but I think it was comparable and they sure seemed healthy." and I had the math relatively handy. Cat food near me is usually $1 - $1.30/lb, getting 28# for $8 is QUITE the...

    old chicken recipie/ or help with what to add for them,

    I only calculated your grain mix. I didn't calculate with the meat addition because I didn't know what meats, in what quantities, and whether fresh (in which case its 75-80% water) or dried to some extent. and again, because different meats, while similar, have differing CP and AA profiles when...

    Looking into Poultry nutrition- Fertrell Questions

    ...Fertrell ALSO has a pre-Mix w/ added Methionine (synthetic, dl-Methionine, allowed for use in "organic" feeds). Since Met is an Amino acid, its both a crude protein booster AND a booster of the most critical amino acid in chicken development. Using that product may well improve rate of...
