There were 35 multiparous and 72 primiparous sheep, with initial ages of 5.6 \u00b1 0.25 years and 1.5 \u00b1 0.01 years, respectively (average overall initial age of 2.8 \u00b1 0.20 years). Wheat straw (4% crude protein; dry matter [DM] basis) was consumed ad libitum and supplemented with approximately 0.15% initial body weight (BW) of soybean meal (LS) or a 1:3 mixture of soybean meal and rolled corn at 1% BW (HS; DM). The supplementation period was 162 days, with the breeding of animals in two sets sequentially, with the pre-breeding period 84 and 97 days, and that after breeding began at 78 and 65 days, respectively. Wheat straw DM intake (1.75, 1.30, 1.57, 1.15, 1.80, and 1.38% BW; SEM = 0.112) was lower (p &lt; 0.05), but average daily gain (\u221246, 42, \u221244, 70, \u221247, and 51 g for DOR-LS, DOR-HS, KAT-LS, KAT-HS, STC-LS, and STC-HS, respectively; SEM = 7.3) was greater (p &lt; 0.05) for HS than LS treatment during the supplementation period. Additionally, changes in body condition score during the supplementation period (\u22120.61, 0.36, \u22120.53, 0.27, \u22120.39, and \u22120.18; SEM = 0.058), and changes in body mass index based on height at the withers and body length from the point of the shoulder to the pin bone (BW\/[height \u00d7 length], g\/cm2) from 7 days before supplementation (day \u22127) to day 162 were \u22121.99, 0.07, \u22122.19, \u22120.55, \u22122.39, and 0.17 for DOR-LS, DOR-HS, KAT-LS, KAT-HS, STC-LS, and STC-HS, respectively; (SEM = 0.297) were affected by supplement treatment. All blood constituent concentrations and characteristics addressed varied with the day of sampling (\u22127, 14, 49, 73, and 162) as well as the interaction between the supplement treatment and the day (p &lt; 0.05), with few effects of interactions involving breed. Birth rate (66.7, 93.5, 84.6, 95.5, 82.8, and 100.0; SEM = 9.83) and individual lamb birth weight (4.50, 4.61, 4.28, 3.98, 3.73, and 3.88 kg; SEM = 0.201) were not affected by supplement treatment (p = 0.063 and 0.787, respectively), although litter size (0.92, 1.21, 1.17, 1.86, 1.12, and 1.82; SEM = 0.221) and total litter birth weight (5.84, 5.74, 5.92, 7.52, 5.04, and 6.78 kg for DOR-LS, DOR-HS, KAT-LS, KAT-HS, STC-LS, and STC-HS, respectively; SEM = 0.529) were greater (p &lt; 0.05) for HS than for LS. In conclusion, although there was some compensation in wheat straw intake for the different levels of supplementation, soybean meal given alone rather than with cereal grain adversely affected BW, BCS, BMI, and reproductive performance, the latter primarily through litter size but also via a trend for an effect on the birth rate. Hence, the supplementation of low-protein and high-fiber forage such as wheat straw should include a consideration of the inclusion of a feedstuff(s) high in energy in addition to nitrogen.<\/jats:p>","DOI":"10.3390\/ani13050814","type":"journal-article","created":{"date-parts":[[2023,2,24]],"date-time":"2023-02-24T03:01:01Z","timestamp":1677207661000},"page":"814","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Effects of the Level and Composition of Concentrate Supplements before Breeding and in Early Gestation on Production of Different Hair Sheep Breeds"],"prefix":"10.3390","volume":"13","author":[{"given":"Farida","family":"Belkasmi","sequence":"first","affiliation":[{"name":"American Institute for Goat Research, Langston University, Langston, OK 73050, USA"},{"name":"Department of Agriculture Sciences, University Mohamed El Bachir El Ibrahimi, El Anasser 34030, Bordj Bou Arreridj, Algeria"}],"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, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2860-7878","authenticated-orcid":false,"given":"Raquel Vasconcelos","family":"Lourencon","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, Langston University, Langston, OK 73050, USA"}],"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, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lionel James","family":"Dawson","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, Langston University, Langston, OK 73050, USA"},{"name":"College of Veterinary Medicine, Oklahoma State University, Stillwater, OK 74078, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luana Paula","family":"dos Santos Ribeiro","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fabiola","family":"Encinas","sequence":"additional","affiliation":[{"name":"American Institute for Goat Research, Langston University, Langston, OK 73050, 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, Langston University, Langston, OK 73050, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,23]]},"reference":[{"key":"ref_1","unstructured":"NRC (2007).
