Protein And Sulfur Amino Acid Nutrition Of Hair Fiber-Producing Angora And Cashmere Goats

    May 2000 in “ Livestock production science ”

    TLDR Giving high-quality protein or methionine supplements helps improve hair growth in Angora goats and, to a lesser extent, in Cashmere goats.
    The study from 2000 investigated the impact of protein and sulfur amino acid nutrition on fiber production in Angora and Cashmere goats. It found that Angora goats had increased fiber yield and diameter with high-quality protein supplements or rumen-protected methionine, while Cashmere goats responded positively to dietary methionine but not to urea or white fishmeal. The research emphasized the importance of sulfur amino acids, particularly methionine, in hair fiber growth, suggesting that methionine could support fiber growth even without cysteine and cystine, though all three are needed for maximum growth. The study highlighted the significant role of targeted amino acid supplementation in enhancing fiber production and addressing nutritional deficiencies in these goats.

      community Can Whey Protein isolate make your AGA worse?

      in Product  10 upvotes 2 years ago
      Whey protein isolate may worsen androgenetic alopecia (AGA) due to its potential to increase DHT levels, but finasteride use has helped maintain hair. Some users suggest avoiding protein supplements due to possible contaminants and additives that could affect hair health.

      Finasteride, dutasteride, saw palmetto, caffeine, spironolactone, acetyltetrapeptides, tea tree oil, hydrocortisone, zinc pyrithione, latanoprost, melatonin, marine protein supplements, PRP, microneedling, and valproate are discussed as treatments for hair loss. DHT reduction and inflammation control are key strategies.

      community Does whey protein and creatine aggravate hair loss?

      in Research/Science  81 upvotes 1 year ago
      The conversation discusses whether whey protein and creatine worsen hair loss. Some users report hair loss with creatine use, while others do not; opinions on whey protein's effects are mixed. Treatments mentioned include PRP, minoxidil, and finasteride.

      community Whey protein and hair loss

       7 upvotes 8 years ago
      Whey protein does not cause hair loss; concerns are likely unfounded. The user is on finasteride and minoxidil but sees no improvement, so they are phasing out these treatments while continuing to work out and use whey protein.
