PHENOTYPIC PARAMETERS IN THE TSURCANA BREED YEARLINGS FROM S.C. EXIM AGRO. OVIS MPS. SRL FIBIŞ - TIMIS COUNTY PARAMETRII FENOTIPICI LA RASA ŢURCANĂ - BERBECUŢI ŞI MIOARE, DE LA S.C. EXIM AGRO. OVIS MPS. SRL FIBIŞ - JUDEŢUL TIMIŞ
2020Co-Authors: Nistor Eleonora, Nistor G, Vasileios BampidisAbstract:Global wool production is approximately 1.3 million tones per annum of which 60% goes into apparel Unfortunately, the total percentage of wool used for textiles has shown a dramatic decline in the past decades, but this has been almost entirely due to the increasing supply of synthetic fibers and the total weight of wool produced has in fact remained fairly static. However, fortunately the demand for natural products has raised the demand for woolen garments, particularly in developed countries. Therefore phenotypic parameters like live weight, fleece weight and Staple Length have been estimated for 100 yearlings’ ewes and rams from S.C. Exim Agro.Ovis MPS. SRL Fibis. Tsurcana yearling ewes had a medium weight of 38.06-±0.165 kg, the grease fleece weight of 2.77±0.198 kg and the Staple Length of 28.49±0.170 cm. Yearling rams were lighter with only 37.57±0.25 kg, while the grease fleece weight was of 3.20±0.19 kg and the Staple Length of 19.16±0.35 cm.

PHENOTYPIC PARAMETERS IN THE TSURCANA BREEDRAMS AND DAMS, FROM S.C. EXIM AGRO. OVIS MPS. SRL FIBIŞ –TIMIS COUNTY
2007Co-Authors: Gh. Nistor, Eleonora Nistor, Vasileios BampidisAbstract:Sheep are a multi-purpose animal, raised for meat, milk, and wool. They are alsovalued for their skins and hides. Increasingly, sheep are being used to controlunwanted vegetation. Sheep can use practically all types of forage, including cropresidue and even ditch banks. An abundance of forage is one key to profitable sheepproduction. In Romania Tsurcana breed is ancient and it is still breed by thefarmers being rustic and eat almost any fodder. In the Tsurcana rams from S.C.Fibis S.A Timis County, the body weight in 2006 was on average of 59.8181-±07264 kg. The same 66 studied rams had a wool production of 3.80±0.056 kg/ ram,while the Staple Length range between 27 and 32 cm, with a mean of 29.4769±0.204cm. The lower value of the variability coefficient of only 5.60% was registered forthe Staple Length of the rams, which means that the genetic structure of thispopulation is homogeneous.

crispr cas9 mediated loss of fgf5 function increases wool Staple Length in sheep
FEBS Journal, 2017Co-Authors: Wenrong Li, Xuemei Zhang, Lei Chen, Xinrong Peng, Sangang He, Liqin Wang, Juncheng HuangAbstract:Fibroblast growth factor 5 (FGF5) regulates hair Length in humans and a variety of other animals. To investigate whether FGF5 has similar effects in sheep, we used CRISPR/Cas9 to generate loss-of-function mutations with the FGF5 gene in Chinese Merino sheep. A total of 16 lambs were identified with genetic mutations within the targeting locus: 13 lambs had biallelic modifications and 3 lambs had monoallelic modifications. Characterization of the modifications revealed that 13 were frame shift mutations that led to premature termination; the other 3 were in-frame deletions. Thus, CRISPR/Cas9 efficiently generated loss-of-function mutations in the sheep FGF5 gene. We then investigated the effect of loss of FGF5 function on wool traits in 12 lambs, and found that the wool Staple Length and stretched Length of genetically modified yearling sheep were significantly longer than that of wild-type control animals. The greasy fleece weight of genetically modified yearling sheep was also significantly greater than that of wild-type sheep. Moreover, the mean fiber diameter in the genetically modified versus wild type sheep showed no significant difference, suggesting that the increase of greasy fleece weight was likely attributed to the increase in wool Length. Our work suggests that CRISPR/Cas9-mediated loss of FGF5 activity could promote wool growth, and consequently increase wool Length and yield. This article is protected by copyright.

Effect of season and Staple Length on wool colour in Corriedale
2009Co-Authors: K. Neimaur, I. Sienra, Roberto KremerAbstract:Wool scoured colour is one of the features that must be improved in Uruguayan Corriedale wool. Yellow discolouration is the main problem and it is related to environmental conditions and individual susceptibility. The objective of this trial was to estimate the effect of season and Staple Length on wool colour through the application of an incubation technique in a Corriedale flock. 63 hoggets were sampled each 6 months during 2 years. 4 treatments were carried out considering Staple Length (short and long wool Staples) and sampling season (winter or summer). A raw wool incubation technique was applied to predict coloration and pre incubation and post incubation clean wool colours (Y-Z) were determined. The results showed a significant increase in post incubation wool colour (Y-Z= 6.98 ± 1.93) with respect to pre incubation colour (Y-Z= 1.88 ± 1.72). The samples extracted in winter with short Staple developed a significant lower colour (Y-Z = 5.69 ± 2.00) than those extracted in summer with 12 months growth (Y-Z = 8.93 ± 2.11) (P

Season of shearing and Length of wool affect wool yellowness in this Corriedale flock.
