Therefore, the objective of this study was to assess the effects of restricted availability of drinking water on blood characteristics and constituent concentrations in different breeds of hair sheep from various regions the USA. For this study, 45 Dorper (initial age = 3.7 \u00b1 0.34 yr), 45 Katahdin (3.9 \u00b1 0.36 yr), and 44 St. Croix (2.7 \u00b1 0.29 yr) sheep from 45 farms in 4 regions of the USA (Midwest, Northwest, Southeast, and central Texas) were used. Ad libitum water intake was determined during wk 2 of period one, with 75% of ad libitum water intake offered during wk 2 of period two, and 50% of ad libitum water intake offered for 5 wk (i.e., wk 5\u20139) in period three. Water was offered at 07:00 or 07:30 h, with blood samples collected at 08:00 and(or) 14:00 h in wk 1, 2, 3, 4, 8, and 9 for variables such as hemoglobin and oxygen saturation and wk 2, 4, 6, 8, and 9 for concentrations of glucose and other constituents. The blood oxygen concentration at 08:00 h was 4.86, 4.93, and 5.25 mmol\/L in period one and 4.89, 4.81, and 5.74 mmol\/L in period three for Dorper, Katahdin, and St. Croix, respectively (SEM = 0.160; p = 0.001). Blood oxygen at 14:00 h was 4.37, 4.61, and 4.74 mmol\/L in period one and 4.66, 4.81, and 5.46 mmol\/L in period three for Dorper, Katahdin, and St. Croix, respectively (SEM = 0.154; p = 0.003). St. Croix were able to maintain a higher (p &lt; 0.001) blood oxygen concentration than Dorper and Katahdin regardless of water availability. The pattern of change in blood concentrations with advancing time varied considerably among constituents. However, concentrations of glucose (55.3 and 56.2 mg\/dL; SEM = 0.84), lactate (24.1 and 22.5 mg\/dL; SEM = 0.79), total protein (7.08 and 7.17 g\/dL; SEM = 0.0781), and albumin (2.59 and 2.65 g\/dL in wk 2 and 9, respectively; SEM = 0.029) were similar (p &gt; 0.05) between periods one and three. Conversely, concentrations of cholesterol (56.2 and 69.3 mg\/dL; SEM = 1.33) and triglycerides (28.6 and 34.5 mg\/dL in wk 2 and 9, respectively; SEM = 0.98) were greater (p &lt; 0.05) in period three vs. 1. In conclusion, water restriction altered almost all the blood variables depending upon severity and duration of restriction, but the hair sheep breeds used from different regions of the USA, especially St. Croix, displayed considerable capacity to adapt to limited drinking water availability.<\/jats:p>","DOI":"10.3390\/ani12223167","type":"journal-article","created":{"date-parts":[[2022,11,17]],"date-time":"2022-11-17T03:26:04Z","timestamp":1668655564000},"page":"3167","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of Restricted Availability of Drinking Water on Blood Characteristics and Constituents in Dorper, Katahdin, and St. Croix Sheep from Different Regions of the USA"],"prefix":"10.3390","volume":"12","author":[{"given":"Ali Hussein","family":"Hussein","sequence":"first","affiliation":[{"name":"American Institute for Goat Research, School of Agriculture and Applied sciences, Langston University, Langston, OK 73050, USA"},{"name":"Department of Animal and Food Sciences, Oklahoma State University, Stillwater, OK 74078, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1410-0902","authenticated-orcid":false,"given":"Amlan Kumar","family":"Patra","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, School of Agriculture and Applied sciences, Langston University, Langston, OK 73050, USA"},{"name":"Department of Animal Nutrition, West Bengal University of Animal and Fishery Sciences, Kolkata 700037, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1824-4436","authenticated-orcid":false,"given":"Ryszard","family":"Puchala","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, School of Agriculture and Applied sciences, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Blake Kenyon","family":"Wilson","sequence":"additional","affiliation":[{"name":"Department of Animal and Food Sciences, Oklahoma State University, Stillwater, OK 74078, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0466-8900","authenticated-orcid":false,"given":"Arthur Louis","family":"Goetsch","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, School of Agriculture and Applied sciences, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"19","DOI":"10.1016\/0921-4488(89)90013-8","article-title":"Influence of Water Restriction on Some Serum Components in Yankasa Ewes","volume":"2","author":"Aganga","year":"1989","journal-title":"Small Rumin.
