AB  - The rate and extent of protein digestion are relevant to broiler performance and 
      health, but information is lacking on the rate of digestion and the 
      characteristics of the undigested fraction for common protein feed ingredients. 
      Therefore, this study evaluated the digestion kinetics and the distal ileum (DI) 
      digesta protein characteristics of protein meals fed to broiler chickens. Using a 
      completely randomized design, 360 male broilers at 14 D of age were assigned to 
      60 battery cages and fed semi-purified diets composed of wheat starch (N-free) or 
      wheat starch with either corn distillers dried grains with solubles (CDDGS), corn 
      gluten meal, meat and bone meal, soybean meal, fish meal (FM), porcine meal 
      (PCM), canola meal, blood meal (BM), or feather meal. At day 21, the protein 
      digestion kinetics and total and soluble protein of the DI content were 
      determined. Differences were considered significant when P </= 0.05. Protein source 
      affected the extent of amino acid (AA) and CP digestibility at the DI. The 
      results demonstrated differences in digesta mean retention time (MRT) and the 
      rate of digestion of AA and CP among protein sources. FM had the shortest MRT of 
      46 min, whereas CDDGS had the longest at 142 min. Both FM and PCM had the highest 
      digestion rates for most of the AA evaluated among the protein sources, whereas 
      CDDGS had the lowest. In turn, the total and soluble CP in the distal ileal 
      contents ranged from 54 to 1466 mg and 6 to 347 mg, respectively. In conclusion, 
      dietary protein source influences the amount and solubility of the undigested 
      protein in the DI and the digestion kinetics of AA and CP along the small 
      intestine of broilers. These parameters may contribute to the effects of protein 
      source on muscle deposition and could influence the impact protein sources may 
      have on gut health through protein fermentation.
