Clinical Cases

A total of 216 local crossbred sheep from 16 scrapie-affected Greek flocks and 210 purebred sheep of the milk breeds Chios and Karagouniko from healthy flocks were analysed for scrapie-linked polymorphisms in the prion protein (PrP) gene. Of the 216 sheep in this case–control study, 96 sheep were clinical cases, 25 subclinical cases (asymptomatic at the moment of euthanasia but positive by histopathology and/or ELISA detecting proteinase-resistant PrP) and 95 healthy controls (negative by all evaluations). Polymorphisms at codons 136, 154 and 171 were determined by denaturing gradient gel electrophoresis, followed by RFLP and sequencing. Scrapie, both clinical and subclinical, was associated with the genotypes ARQ/ARQ (88 of 110 sheep of that genotype), ARQ/TRQ (9 of 13), ARQ/AHQ (15 of 38) and VRQ/VRQ (9 of 17). Histopathological lesions were more severe in the clinical cases. Genotypes ARQ/ARR (26 sheep), ARQ/ARK (seven sheep), AHQ/ARR (one sheep), ARH/ARH (one sheep) and ARR/ARH (three sheep) were detected exclusively in healthy control sheep. In the purebred survey, four genotypes were present in the Chios sheep (ARQ/ARQ, ARQ/TRQ, ARQ/AHQ and ARQ/ARR) and four in the Karagouniko sheep (ARQ/ARQ, ARQ/AHQ, ARQ/ARR and ARQ/ARH).

Electrical Activities

Information regarding normal electrocardiographic features of different breeds of animals can help veterinarians to detect any abnormalities in cardiac electrical activities. The current research was conducted to present the normal electrocardiographic indices of clinically healthy Chios ewes and lambs. The electrocardiograms were recorded from clinically healthy Chios ewes (n=27; 2-3 years old) and lambs (n=20; 4-6 months old) by using base apex lead system. T and QRS-duration in lambs were significantly lower than adult Chios ewes. The electrocardiographic amplitudes in lambs were lower than ewes, non-significantly. P-R, R-R, Q-T and S-T intervals in Chios lambs were significantly lower than ewes. No normal sinus rhythm was detected in Chios lambs. The proportion of sinus arrhythmia and sinus tachycardia in lambs was significantly more than ewes. Sino-atrial block was also detected in lambs. Based on the presented data it could be stated that aging can affect electrocardiographic findings of Chios sheep. Finally, our results will provide a good basis for judging the electrocardiograms in base apex lead system of Chios lambs and ewes.

SUMMARYFriesian cattle, Chios sheep and Damascus goats have become dominant livestock breeds in Cyprus. Chios sheep were found to be superior to the indigenous Cyprus FatTailed and the imported Awassi with respect to precocity, fertility and prolificacy. Awassi performed very well with regard to milk yield and lamb viability. Crossbreds were more or less intermediate. Crosses of Chios with Cyprus Fat-Tailed have contributed substantially to the improvement of milk and meat production from sheep in the country.Damascus goats are very good in litter size and milk yield; a specific strain of the indigenous goat also appears to be a valuable genotype.

SUMMARYSeventy-two Cyprus Fat-tailed and Chios ewes with their lambs were used over a 2-year period to study the effects of three suckling regimes on the lactation performance of ewes and growth rate of lambs. The regimes studied were continuous or 24-hr a day suckling, 12-hr suckling and no suckling. The lambs were weaned at the age of 10 weeks. All the ewes, including those suckling, were handmilked throughout the trial twice daily.Highly significant differences in milk yield (milk sucked by lambs plus milk withdrawn by hand) and lactation length were found between the Fat-tailed and Chios ewes, the respective average milk yields being 159 and 265 kg and the corresponding lactation lengths, 158 and 209 days. There were no significant differences between breeds in the live weight or average daily gain of lambs up to the age of 20 weeks. Suckling for 12 rather than 24 hr a day had no adverse effects on the milk yield of ewes or the growth rate of lambs. The no-suckling regime, however, adversely affected milk yield and lactation length but the effects were less pronounced for the Chios breed.
