This study evaluated the phenotypic trends for wool and growth traits of fine Merino genetic nucleus in Uruguay. Data were collected from one-year-old lambs over a twenty-year period (1999–2018). The overall aim selection flock was to reduce fiber diameter with concomitant increases fleece live weights. Traits analyzed included (FD), greasy weight (GFW), coefficient variation FD (CVfd), staple ...

a crossbreeding experiment involving four iranian fat-tailed sheep breeds, namely kurdi (k), chaal (c), afshari (a) and sanjabi (s) was carried out to determine the ram breed effects on productivity of kurdi fat-tailed ewes (k) under extensive production system. a total of 475 kurdi ewes were mated to 24 rams from four breeds producing 454 lambs including pure kurdi, kk, (116 lambs), afshari × ...

In study, it was aimed to determine the stress effects that can be caused by transporting and altitude in sheep. Karayaka sheeps were used study. are a valuable breed of meat quality fleece, which is raised Black Sea region. The live weight sheep (n = 30) while hungry determined before transport sea level. Average as 55.64 ± 4.66 kg. Blood samples collected just (sea level) after (1500 meters a...

Objective. The objective of this observational cross-sectional study was to investigate associations between farmers’ mental health scores for stress, anxiety, depression, and resilience, sheep welfare outcomes. Materials methods. Twenty-two farms in the departments Boyacá, Cundinamarca, Tolima, Meta, Colombia, were visited once. Clinical health, cleanliness, calmness randomly selected per farm...

Sixteen, 18-month old Merino rams from the SARDI Selection Demonstration Flocks (SDFs) were selected for divergent estimated breeding values (EBVs) for wool production. All sheep had similar total follicle numbers and live weights, and were fed a high-S or a low-S containing diet for 6 weeks prior to the collection of wool samples. Wool growth rate (WGR) and wool S concentration were measured. ...

Genetic and phenotypic parameters were estimated for dagginess, breech, wool, and fiber traits from approximately 29,500 progeny born in 2009 and 2010 in New Zealand dual-purpose ram breeding sheep flocks. Dagginess is adherence of fecal matter to the wool, and this study investigates the genetic and phenotypic correlations between dagginess and breech and wool traits. Estimates for heritabilit...

The adsorption of viruses from aqueous solution is frequently performed to detect viruses. Charged filtration materials capture via electrostatic interactions, but lack the specificity biological virus-binding substances like heparin. Herein, we present three methods immobilize heparin-mimicking, polymers a filter material. Two mussel-inspired approaches are used, based on dopamine or dendritic...
