Case Description- On 23 July 2007, a four-years-old ewe, was referred to Veterinary Clinic of Tabriz Islamic Azad University. The clinical  examination revealed lethargy, weight loss and hematuria in clinical examination. Left kidney in external palpation was painful, enlarged and abnormal. Treatment and Outcome- Laparotomy was done for exploratory diagnosis. In laparotomy the left kidney ...

Lamb growth, survival and carcass characteristics were compared for progeny of either 1/2-Suffolk, 1/2-Rambouillet (Western) ewes or 1/2-Suffolk, 1/4-Rambouillet, 1/4-Finnsheep (1/4-Finn) ewes produced over 3 yr in three different management systems. System 1 lambs were born in late fall and fed to slaughter on a concentrate diet. System 2 lambs were born in January and February and grazed pure...

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 × ...

The effects of two doses of angiotensin II (0.025 micrograms/kg per min and 0.25 micrograms/kg per min) on plasma renin activity (PRA), aldosterone concentration, creatinine clearance, and sodium and potassium excretion were studied in two groups of 2- to 3-week-old lambs. The 0.025 micrograms/kg per min dose of angiotensin II also was studied in six adult ewes. In response to the angiotensin I...

Two, 8-month-old Rambouillet half-sister ewes with signs of visual loss and decreased mentation were examined. Ewe No. 1 was necropsied at 10 months of age, and after being held under observation for a further 6 months, ewe No. 2 was necropsied at 16 months of age. At that time, the ewe was blind and severely depressed. Both ewes had deposition of an autofluorescent lipopigment, identified as c...

(Co)variance components and genetic parameters for test day ewe body weight of Lori-Bakhtiari sheep were estimated using a random regression model (RRM). The data consisted of 22153 individual body weight records, obtained from 1994 ewes (progeny of 205 sires and 1010 dams) between 371 and 3416 days of age, collected from the flock stud of Lori-Bakhtiari Sheep Breeding Station in Shahrekord, Ir...

Effects of environmental factors such as ewe age, season of exposure, and time from lambing to exposure on fertility were evaluated using records on 1,084 Dorset ewes in the STAR accelerated lambing system. The STAR program consisted of five 30-d concurrent breeding and lambing periods per year beginning on January 1, March 15, May 27, August 8, and October 20. Fertility in the flock changed in...

OBJECTIVE To evaluate long-term outcome of autotransplantation of cryopreserved hemi-ovaries into ewes. DESIGN Animal study. SETTING University fertility center, Hospices Civils de Lyon; and Ecole Nationale Vétérinaire de Lyon. PATIENT(S) Grivette ewes. INTERVENTION(S) Six hemi-ovaries from 6 ewes aged 6 to 12 months were frozen with a slow cooling protocol using 2 M of dimethyl sulfoxi...

The 5-yr attrition of 1/4 (n = 411) or 1/2 (n = 403) Finnsheep (Finn) ewes exposed to terminal sire breeds in either an accelerated or semi-intensive annual lambing system was recorded to test the effects of system and percentage Finn on flock age structure at equilibrium. Ewes were culled for discernible ailments and failure to lamb after two consecutive non-spring exposures in yr 3, 4, or 5 o...
