Experimental diets consisted of 4 diets containing each test ingredient as a sole source of nitrogen and a nitrogen-free diet. In experiment 1, 416 male broiler chickens with a mean initial body weight (BW) of 705 \u00b1 100 g were allotted to 5 diets with 8 replicate cages per diet in a randomized complete block design with BW as a blocking factor at day 18 posthatching. After 5 d of feeding experimental diets, birds were euthanized by CO2 asphyxiation, and ileal digesta samples were collected from distal two-thirds of the ileum. In experiment 2, 10 barrows with a mean initial BW of 22.1 \u00b1 1.59 kg were surgically fitted with T-cannulas at the distal ileum and allotted to a duplicate 5 \u00d7 4 incomplete Latin Square design with 5 diets and 4 periods. Each period lasted for 7 d including 5 d of adaptation and 2 d of ileal digesta collection. Data from experiments 1 and 2 were pooled together and analyzed as a 2 \u00d7 4 factorial arrangement with the effects of species (broiler chickens or pigs) and 4 experimental diets (HFM, FDPP, PM, or MBM). There were interactions (P &amp;lt; 0.05) between experimental diets and species in the SID of His, Lys, Thr, Trp, Val, and all dispensable AA except Tyr. In broiler chickens, the SID of Lys in FDPP (73.3%) was greater (P &amp;lt; 0.05) than in HFM (55.7%) but was lower (P &amp;lt; 0.05) than in MBM (86.5%), which was not different from PM (78.7%). In pigs, however, the SID of Lys in FDPP and PM (70.0 and 70.1%, respectively) were greater (P &amp;lt; 0.05) than in HFM (39.0%) but were lower (P &amp;lt; 0.05) than in MBM (79.2%). Broiler chickens fed FDPP and PM had lower (P &amp;lt; 0.05) SID of His, Thr, and Trp than those fed MBM; however, there was no difference in the SID of His, Thr, or Trp among pigs fed FDPP, PM, or MBM. The SID of Val in MBM was greater (P &amp;lt; 0.05) than in the other test ingredients for broiler chickens, but there was no difference in the SID of Val among test ingredients for pigs. Pigs had greater (P &amp;lt; 0.05) SID of Ile and Met than broiler chickens. In conclusion, the pattern of differences in the SID of His, Lys, Thr, Trp, and Val, but not the other indispensable AA, among poultry by-products and MBM were different between broiler chickens and pigs.<\/jats:p>","DOI":"10.1093\/jas\/skaa223","type":"journal-article","created":{"date-parts":[[2020,7,15]],"date-time":"2020-07-15T14:33:22Z","timestamp":1594823602000},"source":"Crossref","is-referenced-by-count":16,"title":["Comparative amino acid digestibility between broiler chickens and pigs fed different poultry by-products and meat and bone meal"],"prefix":"10.1093","volume":"98","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6294-3854","authenticated-orcid":false,"given":"Chan Sol","family":"Park","sequence":"first","affiliation":[{"name":"Department of Animal Sciences, Purdue University, West Lafayette, IN"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Victor Daniel","family":"Naranjo","sequence":"additional","affiliation":[{"name":"Evonik Nutrition & Care GmbH, Hanau-Wolfgang, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John Kyaw","family":"Htoo","sequence":"additional","affiliation":[{"name":"Evonik Nutrition & Care GmbH, Hanau-Wolfgang, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olayiwola","family":"Adeola","sequence":"additional","affiliation":[{"name":"Department of Animal Sciences, Purdue University, West Lafayette, IN"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2020,7,15]]},"reference":[{"key":"2020082817424034000_CIT0001","doi-asserted-by":"crossref","first-page":"420","DOI":"10.3382\/ps.2013-03495","article-title":"Standardized ileal amino acid digestibility of meat and bone meal and soybean meal in laying hens and broilers","volume":"93","author":"Adedokun","year":"2014","journal-title":"Poult.
