A divergent Artiodactyl MYADM-like repeat is associated with erythrocyte traits and weight of lamb weaned in domestic sheep. by Michael V Gonzalez, Michelle R Mousel, David R Herndon, Yu Jiang, Brian P Dalrymple, James O Reynolds, Wendell C Johnson, Lynn M Herrmann-Hoesing, Stephen N White

“…A genome-wide association study (GWAS) was performed to investigate seven red blood cell (RBC) phenotypes in over 500 domestic sheep (Ovis aries) from three breeds (Columbia, Polypay, and Rambouillet). A single nucleotide polymorphism (SNP) showed genome-wide significant association with increased mean corpuscular hemoglobin concentration (MCHC, P = 6.2×10(-14)) and genome-wide suggestive association with decreased mean corpuscular volume (MCV, P = 2.5×10(-6)). …”

Cardiovascular consequences of maternal obesity throughout the lifespan in first generation sheep. by Christopher L Pankey, Qiurong Wang, Jessica King, Stephen P Ford

“…Therefore, we hypothesized that diet-induced obesity during gestation would result in adverse cardiovascular phenotypes in first-generation offspring that would have functional consequences in juvenile and advanced ages. Multiparous Rambouillet/Columbia cross ewes (F0) were fed a highly palatable, pelleted diet at either 100% (CON), or 150% (OB) of National Research Council recommendations from 60 days prior to conception, until necropsy at d 135 (90%) of gestation (CON: n = 5, OB: n = 6), or through term for lambs (F1: 2.5 mo. old; CON: n = 9, OB: n = 6) and ewes (F1:9 years old; CON: n = 5, OB: n = 8). …”

The Structure, Evolution, and Gene Expression Within the Caprine Leukocyte Receptor Complex by John C. Schwartz, Nicholas D. Sanderson, Nicholas D. Sanderson, Derek M. Bickhart, Timothy P. L. Smith, John A. Hammond

“…We identified conserved KIR genes common to both goats and sheep and confirm a partial sheep haplotype shared between the Rambouillet and Texel breeds. Goats and sheep have independently expanded two novel KIR subgroups, and unlike cattle or any other mammal, they do not appear to possess a functional 3DL-lineage KIR gene. …”

“…The use of byproducts such as field pea (Pisum sativum) is an alternative to feed sheep, the objective of this study was to evaluate the intake and digestibility in sheep fed different levels of field pea hay (FPH). Twenty Rambouillet lambs (with an initial BW of 26.0 ± 0.43 kg) were fed to one of four treatments of 5 animals of each (0%, 25%, 50% and 75% inclusion of PH as dry matter basis). …”

Seroprevalence and risk factors of Brucella ovis in domestic sheep in Wyoming, USA by Molly Elderbrook, Brant Schumaker, Todd Cornish, Dannele Peck, Kerry Sondgeroth

“…Aged sheep (≥ 6 years of age) had the highest seroprevalence among age groups; hence, we propose the separation of young rams from older rams to help reduce disease spread outside the breeding season. Wool breeds (Rambouillet and Merino) may be less susceptible to B. ovis infection given they had the lowest animal seroprevalence of the breed types, and large flocks (> 100 breeding rams) had the highest seroprevalence of the flock size categories, likely due to more intensive management strategies that can contribute to the introduction and persistence of B. ovis infection in sheep and flocks.…”
